referring now specifically to fig1 , an exploded view of the urine control device 10 to be employed downstream of a catheter , such as a foley catheter 11 that has been inserted into the bladder 112 of a patient 111 as shown in fig6 . the urine control device 10 includes an upper or first lumen 82 which connects to the foley catheter 11 and forms a passageway to receive urine fluid 120 a from the bladder 112 . the lumen 82 is connected to an input port 12 of the urine control device 10 . in some embodiments , a sterile input port cover 18 is adapted to be fit atop the barbed input port 12 to keep the barbed input port 12 clean . the sterile input port cover 18 is removed and the upper lumen 82 frictionally interfits onto a central aperture 13 on the top of input port 12 . a lower or second lumen 84 is frictionally secured onto a barbed exit port 29 of the urine control device 10 and a locking cap microport cover 30 may secure the lumen 84 thereon . in other embodiments , a kit would be formed with the foley catheter 11 , and the first lumen 82 may already be secured in the input port 12 and the second lumen 84 may also already be secured to the exit of the barbed exit port 29 . first lumen 82 forms the beginning of a central passageway 86 for urine fluid 120 a to flow through the entire length of the urine control device 10 . the flow of the urine fluid 120 a is shown in fig8 a . the second lumen 84 completes the central passageway 86 from the urine control device 10 to the urine collection bag 110 . depending from the bottom of the input port 12 is a detent cylindrical element 62 having a cylindrical sidewall 63 . cylindrical element 62 includes the central passageway 86 . a sampling port 16 is provided through the cylindrical sidewall 63 of the cylindrical element 62 to provide access to the central passageway 86 and to the urine fluid 120 a therein . sampling port 16 has a self sealing silicone plug 16 a to provide access for a sample of urine when required . directly below and integral with the cylindrical element 62 is the upper , or inlet or first housing 60 and an attachable lower , outlet or second housing 14 . therewithin , magnet housing 20 is supported within first housing 60 by a friction fit . referring to fig3 and 4 , magnet housing 20 includes a top aperture 68 to receive stationary magnet 22 securely therein . stationary magnet 22 is press fit into aperture 68 and therefore is fixed in aperture 68 and does not move . to further secure stationary magnet 22 , an inwardly facing radial lip 150 is provided about the upper circular perimeter of the aperture 68 . as best seen in fig1 and fig5 a , a flap magnet retention device 26 forms a lower boundary for the movable flap magnet 24 in a region at the bottom of the magnet housing 20 . the lower magnet retention device 26 has a top opening 64 , a cylindrical sidewall 70 , a bottom opening 72 , and a pair of perpendicular narrow strips 74 . the pair of perpendicular narrow strips 74 are located at the bottom opening 72 and are connected to the cylindrical sidewall 70 forming a barrier for flap magnet 24 . this barrier formed by strips 74 prevents the flap magnet 24 from exiting magnet retention device 26 . the strips 74 of retention device 26 also serve to limit the angle of the opening of flap magnet 24 , and prevent flap magnet 24 from moving into the bowl or chamber 17 of the second housing 14 except within retention device 26 . preferably , an interior height 27 a of retention device 26 is not greater than approximately the diameter of lower magnet 24 . the first housing 60 and the exit second housing 14 are preferably manufactured from k - resin ® ( a registered u . s . trademark of chevron phillips chemical company lp ltd . of woodlands , tex . ), a polycarbonate , which has a material property of being transparent . other materials may be employed provided they have the required material properties . the magnet housing 20 is preferably manufactured from silicone . this would include medical grade silicone which has a hardness value of 4 (+/−) 1 shore a as measured on a durometer . this gives a range of about 3 - 5 shore a . other materials may be employed provided they have the required material properties . in this discussion , and best seen in fig8 a , the urine fluid flow 120 is shown passing through the urine flow control device 10 . the urine fluid flow 120 shows the flow path of urine fluid 120 a through the urine flow control device 10 . the magnet housing 20 , includes a rim or annular shoulder 80 . magnet housing 20 fits within first housing 60 such that should 80 fits into chamber 88 and against inner wall 88 a within diameter d 2 . shoulder 80 is dimensioned appropriately such that the height of shoulder 80 is slightly greater than wall 88 a such that when second housing 14 is interfit into first housing 60 shoulder 80 will be compressed to create a compression seal against the top edge 77 of magnet retention device 26 and against top edge 15 of second housing 14 . the bottom central portion of shoulder 80 includes a flat annular ring 81 . above the shoulder 80 are four openings 98 which pass through the outer sidewall 144 of the magnet housing 20 as shown in fig9 and 10a . the openings 98 must be sufficiently large to permit struvite crystals or other stones or crystals which be entrained in the urine fluid flow 120 to pass through the openings 98 . by making the openings 98 large enough , blockage by the struvite crystals or other material that may be entrained in the urine fluid flow 120 is prevented . when flap magnet 24 is in the open position as shown if fig4 and fig8 a , urine fluid 120 will flow though the four openings 98 , through aperture 105 , over flap magnet 22 and into the second housing 14 which has an ovoid internal shape , in a swirling action . this swirling action of the urine fluid flow 120 a is shown in fig8 a and fig1 . in fig8 a the vortex flow is created and is shown with a portion of the urine fluid 120 a shown in a vortex as the urine fluid 120 flows from above and against flap magnet 24 into and through the interior bowl - shaped chamber 17 of second housing 14 leading to a drain aperture 17 a at the base of chamber 17 . chamber 17 includes an internal annular wall region 17 b extending from the drain aperture 17 a towards the magnet retention device 26 . also see fig7 a . fig8 a shows a symbolic portion of the urine flow 120 in second housing 14 to illustrate the vortex , swirling or tornado effect within chamber 17 . this effect is based on bernoulli &# 39 ; s principles that for an inviscid fluid ( ideal fluid with no viscosity ) flow , an increase of speed of the fluid occurs simultaneously with a decrease of pressure . thus , when the internal body pressure of the bladder 112 and the urine flow 120 reaches a pressure in the range of 7 . 5 - 10 . 5 inches of h 2 o , flap magnet 24 releases in a hinging motion directing the urine fluid flow 120 into a direction which will optimize the direction and flow of urine 120 a such that the increased speed of the urine flow 120 will cause flap magnet 24 to remain in an open position until the magnetic attraction between stationary magnet 22 and flap magnet 24 reaches a level that the flap magnet 24 will close because of the greater attraction of stationary magnet 22 . as a result , the direction of the hinged flap magnet 24 , with bernoulli &# 39 ; s principal of the fluid flow 120 , will develop a tornado effect within chamber 17 with the urine flow 120 which will increase the speed of the urine flow 120 and maintain a steady downward force keeping the flap magnet 24 open until the bladder 112 has been efficiently voided of urine 120 . it is noted that bowl - shaped chamber 17 as shown preferably has relatively smooth internal walls , an annular wall region extending longitudinally from the drain aperture 17 a , and the bowl - shaped chamber is free of any structures , within the annular wall region that would be disruptive to a vortex flow further , chamber 17 would not include any internal structure that would disrupt or inhibit a vortex flow . in a working example , the distance between the stationary magnet 22 and flap magnet 24 is 0 . 630 inches + 0 . 005 /− 0 . 000 inches . the gauss strength of the stationary magnet 22 is 1225 . 0 +/− 10 . 0 gauss . the gauss strength of the flap magnet 24 is 635 . 0 +/− 15 . 0 gauss . the pressure of the liquid to open the flap magnet 24 is 7 . 75 - 10 . 5 inches / h 2 o . the amount of the surface area of the flap magnet subject to pressure is a =( pi )( r 2 ). the diameter of the opening 105 is 0 . 201 inches , the radius of the opening 105 is 0 . 1005 inches . the stationary magnet 22 and the flap magnet 24 are oriented in such a fashion that the magnetic fields attract . it is well known that magnets have poles , one positive or north , designated by ( n ) and one negative or south , designated by ( s ). the stationary magnet 22 may have a bottom portion 34 which is north ( n ) and a top portion 32 which is south ( s ). in this arrangement , the flap magnet 24 will have a top portion 36 which is south ( s ) and a bottom portion 38 which is north ( n ). this arrangement is best seen in fig3 and 4 . alternatively , the stationary magnet 22 may have a bottom portion 34 which is south ( s ) and a top portion 32 which is north ( n ). in this case , the flap magnet 24 must have a top portion 36 which is north ( n ) and a bottom portion 38 which is south ( s ). this alternative embodiment is not shown in the fig3 and 4 . in either of these magnet arrangements , the flap magnet 24 is attracted to the stationary magnet 22 . both the flap magnet 24 and the stationary magnet 22 are generally cylindrical with a diameter and height . the stationary magnet 22 and the flap magnet 24 may be of different or have generally the same diameter ; however , generally the height of the stationary magnet 22 is greater than the flap magnet 24 . the diameter or length l 2 of the flap magnet 24 is chosen to be greater than the distance l 1 formed starting from the inner sidewall 26 a of the magnet retention device 26 to the far side of aperture formed by the bottom of the central urine passageway 105 . this is best seen in fig8 b . in the event that flap magnet 24 gets loose , it will always close having sufficient diameter l 2 to completely arrest the urine fluid flow through the central urine passageway 105 . in a working example , stationary magnet 22 has a diameter of 0 . 361 inches and a height of 0 . 253 inches and has a gauss value of about 1225 . 00 (+/−) 10 . 0 with the north side of the stationary magnet 22 in the towards input port 12 the flap magnet 24 has a diameter of 0 . 375 inches and a height of 0 . 091 inches and a gauss value of about 635 . 00 (+/−) 15 . 0 with the same orientation of north as the stationary magnet 22 . when the pressure in the first housing 60 reaches about 7 . 75 to 10 . 5 inches of h 2 o [ pure water at 4 degrees centigrade ], the flap magnet 24 opens in a hinge like action . the opening of the flap magnet 24 is in response to sufficient pressure bearing down on the top 36 of the flap magnet 24 through aperture 105 . when the flap magnet 24 is in an open position , it directs the urine fluid flow 120 in a specific direction into the chamber 17 of second housing 14 which starts the vortex action . this is because the flap magnet 24 hingedly opens and the urine fluid flow 120 is directed against and over flap magnet 24 to one side and downward into the chamber 17 of second housing 14 . through action of bernoulli forces , the chamber 17 of second housing 14 has a lower internal pressure than the pressure in chamber 88 of first housing 60 drawing the urine fluid 120 a into the second housing 14 . the internal shape of chamber 17 of second housing 14 combined with the lower pressure in chamber 17 induces the urine fluid flow 120 to move in a vortex or swirling motion as it passes over and against flap magnet 24 and into the chamber 17 and through second housing 14 to the drain aperture 17 a . the combination of the lower pressure , the induced vortex , and the directional flow over the flap magnet 24 when flap magnet 24 is in the open position aids in draining the urine fluid 120 a more completely from device 10 and the bladder 112 . this aids in removing the old , rancid , possibly infected urine fluid 120 a which may remain in the bladder 112 when using a prior art conventional continuous flow catheter . this magnetic attraction between the stationary magnet 22 and flap magnet 24 holds the lower magnet 24 magnetically to the bottom side of shoulder 80 and to annular ring 81 . when flap magnet 24 is in a closed position , it blocks and prevents the urine fluid flow 120 through the passageway 86 and through aperture 105 towards the second housing 14 . as shown in fig3 the flap magnet 24 top portion 36 is in a closed position below central valve urine passageway 105 of shoulder 80 . however , the flap magnet 24 will move to an open position when the critical pressures exceed the magnetic attraction between the stationary magnet 22 and the flap magnet 24 . due to the magnetic field lines between the stationary magnet 22 and the flap magnet 24 , when the flap magnet 24 opens , the flap magnet 24 moves in an angular fashion creating an opening in the passageway 105 which opens passageway 86 allowing urine fluid flow 120 to continue within passageway 86 below the position of flap magnet 24 . when the critical pressure overcomes the magnetic attraction threshold between the stationary magnet 22 and the flap magnet 24 , the flap magnet 24 opens angularly as shown in fig4 . the maximum open position of flap magnet 24 will be until flap magnet 24 rests against one or more of the perpendicular narrow strips 74 of the lower magnet retention device 26 . the ability of the flap magnet 24 to open in an angular fashion is attributed to the arrangement of the fixed , unmovable stationary magnet 22 with respect to the angularly movable flap magnet 24 . in this arrangement magnetic fields are generated by the stationary magnet 22 which attract , support and hold the flap magnet 24 against the shoulder 80 and lip 81 . additionally the flap magnet 24 generates magnetic fields which attract the stationary magnet 22 . when the critical pressure is greater than , and thus overcomes , the attractive forces between the upper stationary magnet 22 and the movable flap magnet 24 then the lower stationary magnet 24 is angularly displaced until at a maximum , a portion of flap magnet 24 rests on the lower magnet retention device 26 . due to micro - discontinuities and uneven magnetic fields generated and interacting between the stationary magnet 22 and the movable flap magnet 24 , the movable flap magnet 24 will move downward in an angular fashion , with one part of the top portion 36 of the movable flap magnet 24 resting against lip 81 of shoulder 80 or magnetically closely attracted to shoulder 80 and lip 81 . the bottom portion 38 of flap magnet 24 is towards or resting against the magnet retention device 26 . the silicone magnetic housing 20 frictionally interfits into the upper housing 60 . upper housing 60 rotatably attaches the lower housing 14 to the upper housing 60 securing the magnet housing 20 by a barb 42 located on the interior of the upper housing 60 which fits into a groove 44 located in the lower housing 14 . when the barb 42 is rotated in the groove 44 the upper housing 60 is secured to the lower housing 14 . lower housing 14 has a generally ovoid shaped inner chamber 88 . depending from the bottom of the lower housing 14 is a barbed exit port 29 to receive lumen 84 . a microport hole 28 passes through the sidewall of the barbed exit port 29 . the microport hole 28 allows atmospheric air to enter the passageway 86 . the microport hole 28 is covered by a microfilter covering 28 a , which attaches by adhesive or is frictionally held to the sidewall of barbed exit port 29 to cover hole 28 . fig5 a shows three of the four microport holes 28 which provide a passageway for entry of the atmospheric air through the microport holes 28 . holes 28 covered with microport covering 28 a allow air into passageway 86 but do not allow fluid flow 120 to exit through hole 28 . hole 28 allows for pressure equalization in the device 10 and create tiny cleansing bubbles of air that travel down the passageway 86 to the collection bag 110 . cover 30 has for openings 28 b to allow atmospheric communication to hole 28 . this introduction of atmospheric air which contains approximately twenty percent ( 20 %) oxygen is biocidal to many microorganisms . the atmospheric oxygen which enters through the microfilter covering 28 a and into the microport hole 28 flows into passageway 86 and into lumen 84 . lumen 84 forms the remainder of passageway 86 and the urine fluid flow 120 continues along passageway 86 to the urine collection bag 110 . the biocidal properties of the oxygen entering through the microport hole 28 prevents bio - film from forming on the interior passageway 86 , of the second lumen 84 and the interior of the collection bag 110 . the bio - film formation is arrested due to the fact that the gaseous oxygen kills the microorganisms . this helps prevent reflux and microbiological contamination of the urine flow control device 10 and the associated catheter and urine collection bag 110 . by preventing such reflux , urinary tract infections are reduced . referring now specifically to fig2 a , a plan view of the upper portion of the urine control device 10 including the barbed input port 12 and the upper housing 60 is shown . a cylindrical element 62 is shown intermediate the barbed input port 12 and the upper housing 60 . a silicone plug 16 a is shown passing through the sidewall of the cylindrical element 62 . the self sealing silicone plug 16 a , permits access to take a sample of the urine fluid 120 a that comes from the patient for any medical tests that may be required . referring now specifically to fig2 b . a cut - away view taken along lines 2 b - 2 b of fig2 a with the silicone cylindrical plug 16 a not in place . a central aperture 13 on the top of barbed input port 12 is designed to receive the first lumen 82 of the catheter therein . a central passageway 86 passes through the center of the barbed input port 12 and then into the center of cylindrical element 62 and then into the generally bell shaped upper portion chamber 88 of the input or first housing 60 . two barbs 42 are located at the bottom 90 of the upper housing 60 , along the interior sidewall 88 b . a sample port 16 passes through the sidewall 63 of the cylindrical element 62 allows sampling of urine fluid 120 a passing through the central passageway 86 . the upper portion chamber 88 of the interior of the upper housing 60 is bell shaped and expands to a maximum diameter d 1 . below the bell shaped upper housing 60 is an interior cylindrical inner sidewall 88 a with a diameter d 2 which is somewhat larger than diameter d 1 . immediately below the interior cylindrical portion sidewall 88 a with a diameter of d 2 is second cylindrical shoulder portion inner sidewall 88 b with a diameter d 3 . diameter d 3 is somewhat larger than diameter d 2 . the internally disposed barbs 42 are located on inner sidewall 88 b , on the portion of the interior upper housing 60 which has diameter d 3 . the reason for the staggered diameters of the interior of the upper housing 60 is so that it may receive the magnet housing 20 therein such that annular shoulder 80 fits within and is frictionally held in place by wall 88 a . once the magnet housing 20 is in place , the lower housing 14 is interfit into the bottom 90 of the first housing 60 , where the barbs 42 fit into a groove 44 , which when rotated , lockably secures the upper housing 60 to the lower housing 14 and the top of second housing 14 has a compression fit against shoulder 80 of magnet housing 20 to form a leak free fit . referring now specifically to fig3 , the magnet housing 20 of urine control device 10 is shown with flap magnet 24 in the closed position . the magnet housing 20 is interfit inside the upper housing 60 . stationary magnet 22 is interfit into stationary magnet housing aperture 68 . stationary magnet housing 68 includes an interior cylindrical sidewall 140 with columns 155 . the columns having a top 142 . the stationary magnet 22 fits into the opening formed by the cylindrical sidewall 140 and rests on surface 142 . fig3 also shows the top portion 32 of the stationary magnet 22 being of a south ( s ) polarity and the bottom side 34 of the stationary magnet 22 being of a north ( n ) polarity . additionally , fig3 shows several of the urine passageways 98 in the magnet housing 20 above shoulder 80 which lead to a central valve urine passageway 105 . central valve urine passageway 105 is part of central passageway 86 and provides the opening for the urine flow 120 from above the magnet housing 20 through magnet housing 20 when the flap magnet 24 is in the open position as shown in fig4 . in fig4 , magnet 24 is shown displaced by the angle 40 . this angle is preferably 30 degrees to 45 degrees . in fig4 , the weight and pressure of the urine flow 120 from the bladder causes the flap magnet 24 to angularly displace , the displacement angle shown at 40 allowing the urine to flow to the lower housing 14 where it then flows to the urine collection bag 110 . the urine flow 120 through the urine control device 10 will be best seen in fig5 a and fig8 a , where the direction of flow is indicated by arrows and line 121 in fig5 a . at the bottom of the second housing 14 is at least one micropore hole 28 which is seen best in fig7 a . the microport hole 28 is covered by a microport filter 28 a which may be attached with an adhesive and permits outside air to enter the urine stream through microport hole 28 while not permitting the urine stream from leaving the urine control device 10 . such micro filter 28 a is manufactured by tapespec ® of new zealand . a microport cover 30 covers the micropore hole 28 and microport filter adhesive 28 a when desired which is shown in fig1 . the air introduced into the urine flow 120 is approximately 20 % oxygen which is a highly toxic gas for many types of microorganisms . the oxygen is quite lethal and creates a hostile environment which kills many microorganisms in the second lumen 84 and urine retention bag 110 . this prevents or minimizes the possibility of infection of the patient and extends the length of time before the urine retention bag 110 would need to be replaced . referring specifically to fig5 b a plan view of the urine control device 10 is shown assembled . the first housing 60 is shown connected to the second housing 14 . once the sterile input cover 18 is removed , the upper lumen 82 is fit over the barbed input port 12 . the microport cover 30 is affixed over the barbed exit port 29 . referring specifically now to fig6 , a view of the urine control device 10 placed in line with the first lumen 82 of a catheter which has been inserted into the bladder 112 of the patient 111 and a second lumen 84 connected to a urine collection bag 110 is shown . this is generally how the urine control device 10 is employed with a foley catheter 11 inserted into a patient 111 . the catheter 11 drains the urine fluid 120 a from the bladder 112 to the urine flow control device 10 . in many cases , but not all , the urine storage bag 110 may be attached to a leg by a band 110 a . a luer lock connector 110 b allows air to fill a balloon 110 c once the foley catheter 11 is inserted into the bladder 112 . when the balloon 110 c is inflated the catheter 11 will remain in the bladder 112 . referring now specifically to fig7 a a sectional view of the urine control device 10 with the flap magnet 24 in the closed position , preventing any urine flow 120 from the bladder and above second magnet 24 . central passageway 86 provides a channel for urine flow 120 . flap magnet 24 is held against a flat annular ring 81 by the magnetic attraction between first magnet 22 and flap magnet 24 . the diameter of the flap magnet 24 is chosen to be such that when flap magnet 24 is in a closed position within magnet retention device 26 , the central urine passageway 105 through the flat annular ring 81 will be completely blocked and sealed by flap magnet 24 . annular ring 81 prevents the top 36 of the flap magnet 24 from becoming vacuum locked against shoulder 80 . fig7 b is an enlarged view of the portion of the urine control device 10 shown in the circled area of fig7 a . fig7 b shows the spatial arrangements of a portion of the annular shoulder 80 , the annular ring 81 , the flap magnet 24 in a closed position , the bottom 152 of the annular shoulder 80 , the intersection of the top 27 of the magnet retention device 26 with the bottom 152 of the annular shoulder 80 , the intersection of the top 15 of second housing 14 , with both the bottom 152 of the annular shoulder 80 and the step down 160 between the inner sidewall 88 a and interior sidewall 88 b . annular shoulder 80 extends a small distance below inner wall 88 a . shoulder 80 is made of medical grade silicon or equivalent and both the magnet retention device 26 and the second housing 14 are made from a polycarbonate of a k resin type or equivalent . the medical grade silicon forms an elastic compression gasket 162 at the point of the compression of shoulder 80 by the top 15 of second housing 14 and the top 27 of retention device 26 . this elastic compression gasket 162 seals the intersection of element 15 and element 152 averting the possibility that any urine fluid 120 a may escape . in fig7 b , the compression gasket is shown in a compressed state . barb 42 is shown locked in groove 44 preferably forming a one - time connection between the first housing 60 and the second housing 14 . the urine flow control device 10 is designed for a one time use , not to be reused . if the first housing 60 and the second housing 14 are forced open , the barb 42 would fracture and it would not be possible to put the first housing 60 and the second housing 14 together again . referring now specifically to fig8 a a sectional view of the urine control device 10 with the flap magnet 24 being forced to an open position by the pressure and the weight of the urine in the bladder 112 and the first lumen 82 , allowing the urine to flow to the second housing 14 , to the second lumen 84 , and then to the urine collection bag 110 . the flap magnet 24 is hingedly displaced in an angular fashion , and is shown as the angle designated by the curved line 40 in fig4 . flap magnet 24 opens angularly as indicated by the curved line shown at element 40 . the angle may vary to any angle within the range of above zero degrees to about 60 degrees where it is stopped by the lower magnetic retention device 26 . the momentum of the urine flow 120 along the passageway 86 is caused by the pressure exerted by the bladder 112 , the weight of the urine fluid 120 a itself , and the velocity of the urine fluid 120 a in the urine flow 120 . when the momentum of the urine fluid 120 a in the urine flow 120 falls below a critical level , the flap magnet 24 moves angularly back to the closed position , closing off the urine flow 120 in the passageway 86 and the central urine passageway 105 through the center of the shoulder 80 . the urine flow 120 starts in the bladder 112 and proceeds through the first lumen 82 to the top of the urine control device 10 . the urine flow 120 exits the first lumen 82 into the upper part of the urine control device 10 where it enters a central passageway 86 and proceeds into the inside of the bell shaped first housing 60 . the central passageway 86 is the passageway for the urine flow 120 which passes through the urine control device 10 . inside the bell shaped input housing 60 is the magnet housing 20 . the flap magnet 24 blocks the urine flow 120 and causes the urine flow 120 to move to the region intermediate the inner sidewalls 125 of the bell shaped input housing 60 and the area where the magnet housing begins . this allows the urine flow 120 to flow about the magnet housing 20 . this opening between the inner sidewalls 125 of the bell shaped input housing 60 and the outer sidewalls 144 of the magnet housing 20 is part of the passageway 86 and provides for the urine flow 120 down the outer sidewalls 144 of the magnet housing 20 until the urine 120 reaches the shoulder 80 . a distance d seen in fig3 exists between the outer sidewall 144 of the magnet housing 20 and the inner sidewall 125 of housing 60 . above the shoulder 80 are the outer sidewalls 144 of the magnet housing 20 showing the four openings 98 which connect to the central urine passageway 105 which is best seen in fig9 . located on the interior side of the interior cylindrical sidewall 140 are a plurality of vertically oriented shoulders 155 . these act as a bottom support for the stationary magnet 22 . the stationary magnet 22 bottom portion 34 rests upon the top 142 of the aforementioned shoulders 155 . this , in combination with the stationary magnet securing lip 150 keeps the stationary magnet 22 in place and stationary . at the bottom of the outer sidewalls 144 of the magnet housing 20 there are four openings 98 . the urine flow 120 enters the four urine passageway openings 98 located above the shoulder 80 which lead to a central urine passageway 105 , which allows the urine flow 120 to pass from the upper housing 60 through the passageway 105 to the top portion 36 of the flap magnet 24 . at this point , the forces of the magnetic attraction between the stationary magnet 22 and the flap magnet 24 are opposed by the weight of the urine 120 , the force of pressure of the urine from the bladder , and any momentum from the urine flow 120 . when the force of the urine in the urine flow 120 overcomes the magnetic attraction force between the stationary magnet 22 and the flap magnet 24 the urine will cause flap magnet 24 to move angularly downward to an open position . at this point the urine flow 120 is through the central urine passageway 105 back to the central passageway 86 into the ovoid shaped lower exit housing 14 . the urine flow 120 takes on a vortex or tornadic path into and inside the ovoid shaped or bowl - shaped chamber 17 of second housing 14 . this vortex or tornadic path inside the chamber 17 of second housing 14 creates a low pressure area within chamber 17 , lower pressure than in first housing 60 which increases the velocity and momentum of the urine flow 120 along the passageway 86 helping to empty the bladder 112 more completely . the urine flow 120 then enters the hollow center of the barbed exit port 29 where it is connected with the second lumen 84 and finally the urine flow 120 discharges into the urine collection bag 110 after the bladder 112 has been emptied . fig8 b is an enlarged up view of the portion of the urine control device shown in the circled area of fig8 a . fig8 b shows the spatial arrangements of a portion of the annular shoulder 80 , the annular ring 81 , the flap magnet 24 in an open position , the bottom 152 of the annular shoulder 80 , the bottom 153 of annular ring 81 the intersection of the top 27 of the flap magnet retention device 26 with the bottom 152 of the annular shoulder 80 , the point of contact of outer wall 165 of the flap magnet retention device 26 and the inner wall 165 a of second housing 14 . flap magnet 24 is shown in an opened position , hingedly open at an angle shown and described by the curved line 40 . when flap magnet 24 is opened , the upper left corner 176 of the flap magnet 24 may touch a point 172 of the bottom 152 of annular shoulder 80 . additionally , point 178 on the top 36 of the flap magnet 24 may touch the point 174 on the bottom 153 of flat annular ring 81 . further , the lower 38 right corner 180 of flap magnet 24 may touch at point 182 or nearby by intersecting a point 182 on the pair of perpendicular narrow strips 74 which traverse the bottom opening 72 of the flap magnet retention device 26 . flap magnet 24 may hingedly open in any radial direction , point 172 may be anywhere in a ring of positions located on the bottom 152 of the annular shoulder 80 . fig8 b shows one possible configuration with the flap magnet 24 opened . as such , the previous paragraph describes what is shown in fig8 b . the flap magnet 24 could be oriented where the upper right corner 184 would be intersecting a point at the bottom 152 of annular shoulder 80 . in this case , the flap magnet 24 would be opening 180 degrees ( not shown ) from the orientation shown in fig8 b . fig9 is a perspective view of the magnet housing 20 showing the four openings 98 in which the urine flow 120 enters , to further pass through the central urine passageway 105 located centrally and through the shoulder 80 . the urine flows through the plurality of openings 98 , passes down through the central urine passageway 105 and comes in contact with the top 36 of the lower magnet 24 . when the urine fluid 120 a in the urine flow path 120 reaches a critical force value which overcomes the magnetic attraction between the stationary magnet 22 and flap magnet 24 , the flap magnet 24 angularly opens as if on a hinge . thereafter when the urine fluid 120 a is emptied , flap magnet 24 returns to the closed position closing the central urine passageway 105 once the forces of the urine fluid 120 a in the urine flow path 120 falls below the critical value . because of the tornado or vortex effect in chamber 17 the urine flow 120 will continue and allow the urine above flow magnet 24 to empty into chamber 17 and be discharged from the urine control device 10 . fig1 a is a side view of magnet housing 20 of the urine control device 10 . the top 151 of annular shoulder 80 connects through the four openings 98 in the magnet housing 20 to the central urine passageway aperture 105 . the top 151 of the annular shoulder 80 acts as a floor which passes into the interior of the magnet housing 20 to the central urine passageway aperture 105 . fig1 b is a top view of the magnet housing of the urine control device 10 with the stationary magnet 22 removed . it can be seen that the top 151 of the annular shoulder 80 passes into the interior of the magnet housing 20 to the central urine passageway aperture 105 . four vertical columns 155 are shown about 90 degrees apart , the bottom 34 of the stationary magnet 22 would rest on the top 142 of each of these four vertical columns 155 . an upper lip 150 is shown which would hold the top 32 of the stationary magnet 22 keeping the stationary magnet 22 fixed intermediate the upper lip 150 and the top of the four columns 155 . the upper lip 150 also ensures that the urine flow 120 does not enter the portion of the magnet housing 20 where the stationary magnet 22 resides . fig1 c is a bottom view of the magnet housing 20 of the urine control device 10 . the central urine passageway aperture 105 is shown passing through both the annular shoulder 80 and the flat annular ring 81 which depends centrally from the bottom 152 of the annular shoulder 80 . the bottom 153 of the flat annular ring 81 is shown . fig1 d is a view of the magnet housing of the urine control device taken along lines 10 d - 10 d of fig1 a . the top 151 of the annular shoulder 80 passes into the interior of the magnet housing 20 to the central urine passageway aperture 105 . four vertical columns 155 are shown in section and about 90 degrees apart , the bottom 34 of the stationary magnet 22 would rest on the top of each of these four vertical support columns 155 . fig1 e is a sectional view of the magnet housing 20 of the urine control device 10 taken along lines 10 e - 10 e of fig1 a . the first housing 60 and second housing 14 are connected with twist - lock assemblies to assure the first housing 60 and second housing 14 are connected correctly and without adhesives . the silicone magnet housing 20 acts like a gasket between first housing 20 and lower magnet 24 to prevent leakage when lower magnet 24 is in a closed position . a urine flow cycle begins with the flap magnet 24 in a closed position . when the fluid pressure reaches 7 . 75 to 10 . 5 inches of h 2 o , the fluid pressure against flap magnet 24 results in a force which overcomes the attraction between the magnet 24 and magnet 22 and opens flap magnet 24 . the force that opens flap magnet 24 is from the fluid pressure zone p 1 in the chamber 88 , which forces flap magnet 24 into an open position . once the flap magnet is open , the fluid pressure p 1 zone is above the restricted passageway of annular opening 105 . p 1 is within chamber 88 and is shown at fig8 a . fluid pressure p 2 in the restricted passageway of annular aperture or opening 105 is greater than fluid pressure p 1 within chamber 88 because of the fluid flowing through the restricted annular opening 105 . according to the bernoulli effect , the velocity of the fluid at the restricted area 105 is faster than the fluid speed in chamber 88 and the area above the annular opening 105 . just downstream and below the opening 105 , the fluid pressure at p 3 is lower or less than fluid pressure p 2 . this lower pressure p 3 causes an increase in the velocity of fluid in the chamber 17 . the bowl - shape of chamber 17 causes a vortex fluid effect in chamber 17 . this vortex can only be maintained with lower pressure p 3 and increased speed of the fluid . the low pressure area p 3 pulls the fluid from above the restricted annular opening 105 and evacuates the remaining fluid above the restricted annular opening 105 while keeping the flap magnet 24 open . the increased velocity of the fluid at the restricted annular opening 105 keeps flap magnet 24 open for a longer period of time counter to the magnetic attraction force between the stationary magnet 22 and flap magnet 24 . the force resulting from the flowing fluid at opening 105 overcomes the magnetic attraction and keeps magnet 24 open while the remaining fluid drains from the bladder and housing 60 . further , as the fluid leaves chamber 17 it pulls outside air into passageway 86 which decreases the fluid pressure which allows the fluid to drain into the collection bag pulling outside air through opening 28 which results in microscopic air bubbles being pulled into the fluid stream in passageway 86 and into collection bag 110 . when the fluid 120 above the flap magnet is drained into chamber 17 and there is little or no fluid left above flap magnet 24 , then flap magnet closes against the magnet housing 20 and the cycle starts over . new fluid enters the bladder 112 and the fluid in the bladder drains to the first housing 60 . when the fluid pressure reaches the critical value of 7 . 5 - 10 . 5 inches of h 2 o against the flap magnet 24 , the flap magnet 24 opens again . while the invention has been described in its preferred form or embodiment with some degree of particularity , it is understood that this description has been given only by way of example and that numerous changes in the details of construction , fabrication , and use , including the combination and arrangement of parts , may be made
