referring now to the drawings in detail and in particular to fig2 , reference character 10 generally designates a cleaning device constructed in accordance with a preferred embodiment of the cleaning device of the present disclosure . fig1 illustrates the device and operations of associated with continuous positive airway pressure ( cpap ) as a treatment for sleep apnea . the device 40 typically is typically what is referred to in the art as a human - interface . it can be a full - face mask or a partial - face mask or a nasal - like device [ as illustrated in fig1 ] which has two nasal ports 45 insertable into a user &# 39 ; s nostrils . it must be understood that the human - interface device 40 as referred to herein could be mask - like or nasal - like with nasal ports 45 . in either event , the purpose of the human - interface device 40 , whether mask - like or nasal - like , it to force air into the user . the cleaning device 10 of this disclosure is adapted to clean both types and is not limited to the nasal - like only . fig1 illustrates the human - interface 40 as nasal - like having nasal ports 45 which fit into one &# 39 ; s nostrils . attachment straps 43 on the device 40 typically fit over the user &# 39 ; s head to hold the device 40 in place while the user sleeps . this device 40 is attached to an air - flow generator 30 via a flexible hose 34 . the flexible hose 34 has attachment interfaces 33 , 35 at each end . one end , the air - flow attachment interface 33 , is connected to the air - flow port 31 of the air - flow generator 30 . the other end , the human - interface device attachment interface 35 , connects to the in - take port 41 of the nasal - interface device 40 . a person suffering from sleep apnea will don the device 40 with hose 34 attached to the device 40 and to the air - flow generator 30 . the air - flow generator 30 will then be turned on which directs a continuous flow of air through the hose 34 , into and through the human - interface device 40 and into the wearer &# 39 ; s nostrils . the air pressure is adjusted to keep the airway open during the night and assist the user in breathing thereby defeating the effects of sleep apnea . as mentioned previously , cleaning such a device 40 , whether nasal - like or mask - like , is cumbersome and many people neglect this task or , in the alternative , discontinue cpap treatment . either option is not desirable from a health - care perspective . the cleaning device of the present disclosure 10 solves this dilemma and simplifies the cleaning process associated with cleaning typical and similar human - interface devices 40 as described herein whether such be mask - like or nasal - like in configuration . the cleaning device 10 of the present disclosure has a solvent - receiving member 11 [ its base ], a hollow inner chamber 24 forward of the base and throughout terminating at the exit opening 25 . the solvent may be water , the universal solvent , or any other commercially available solvent suited for the intended purpose of conveying a solution to and through the human - interface device 40 so as to cleanse it . the base 11 has an opening 15 with two or more axial slits 13 extending outward from the opening 15 toward the perimeter of the base 11 thereby forming the flaps 14 . the opening 15 may be , but need not be , centrally located on the base . the base 11 and its flaps 14 are made of flexible material such as , but not limited to , rubber , vinyl , resilient polymers , or combinations thereof . a side wall 17 extends forward of the base 11 and may be relatively straight [ i . e ., approximately perpendicular to the base 11 ] or may be angled inward to the exit opening 25 . as illustrated , the side wall is relatively straight . an angling wall 21 , angling inward , extends forward of the side wall 17 as seen in fig3 . the angle for the angling wall 21 is referred to as angle - x . the angling wall 21 downward to the exit opening 25 resembles a cone - like structure or extension and defines an angled channel 29 therein . the angles for the angling inward and downward of this wall 21 [ angle - x ] ranges from approximately 30 ° to approximately 60 °. the optimum angles for the intended purpose ranges from approximately 38 ° to approximately 42 °. in this illustration , the angling wall 21 comes to a step or ridge 27 , followed by an tapering attachment wall 26 [ tapering to permit attachment of the flexible hose 34 thereto ] tapering inward to the exit opening 25 at the distal end of the device 10 and defining therein an exit channel 39 . this cone - like extension of angling wall 21 with exit opening 25 , with or without the tapering attachment wall 26 and exit channel 39 , nearly resembles a funnel - type device . the device 10 however , need not have the ridge 27 and , if without the tapering attachment wall 26 , the angling wall 21 should be angled such that it will accommodate attachment of the flexible hose 34 [ dimensions of tapering / angling described below for the tapering attachment wall 26 which is structured to accommodate attachment of the flexible hose 34 ]. fig3 illustrates the proximal end of the angling wall 21 as attached to the distal end of the side wall 17 and has a pre - determined outside and inside diameter which is approximately equal to the outside and inside diameter of the side wall 17 , respectively . from this point of attachment , the angling wall 21 tapers [ inward angling ] to a smaller outside and inside diameter which may continue to the exit opening 25 or to the step 27 as described above . the inner walls of this inner chamber 24 are contoured similarly as the diameters described above for the side wall 17 [ referred to as diameter - y or y ], the angled channel 29 , and the exit channel 39 . consequently , as solvent is forced through the cleaning device 10 , the decreasing inside diameters of the inner chamber 24 , in cases where it is fully angled , or angled only from the angling wall 21 forward will create a greater force of movement of the solvent through the inner chamber 24 and , concomitantly , greater cleansing power . for a greater force of movement of solvent , the inner chamber 24 has one or more elongated , inward extending and forward extending fins 22 [ extending from near to the base 11 forward to the angling wall 21 ]. the fins may extend inward approximately one - eighth to one - fourth of diameter - y and may be perpendicular to the side wall 17 or angled . angling may be diagonally off the sidewall 17 at approximately between 10 ° to approximately 30 ° as viewed from the axis of the inner chamber 24 . this angling is referred to as angle - s [ fig4 refers ]. with three or more such fins 22 inside the inner chamber 24 , a fin channel 19 is defined within the fins 22 . the fins 22 act as channel directors to keep the solvent flowing evenly and forward without causing any undue sideward movement . the more direct the movement of solvent through the device 10 , the greater the force and cleaning power of the solvent . the fins 22 may be relatively straight [ as illustrated in fig4 ] or have an angled flap 23 at the bottom toward the exit opening 25 [ as illustrated in fig3 ]. such angling should not generally be an abrupt angle with a sharp corner of demarcation but should be a curved transition into the angling as illustrated in the respective figure . such an angled flap 23 will increase the force of flow of solvent . each angled flap 23 should be angled in the same direction and such angled is referred to as angle - z . angle - z ranges from between approximately 10 ° to approximately not more than 45 ° with respect to the fin 22 to which connected . the length of the angled flap 23 should about 20 % to about 35 % of the total length of the fin 22 / flap 23 combination . as solvent flows through the inner chamber 24 and fin channel 19 and comes into contact with the angled flaps 23 , a tornado effect is created which generates even more force of flow of the solvent . there is a tapering attachment wall 26 extending downward from the bottom of the angling wall 21 to the exit opening 25 . this tapering is important and its relative decreasing downward diameters for permitting a secure fit of the flexible hose 34 and its interface 33 thereto . typically the outside diameter of the interface 33 of the flexible hose 34 is approximately 21 mm . the outside diameter of the tapering attachment wall 26 , at is distal end [ i . e ., at the exit opening 25 ] should be less than 21 mm and the diameter increases to a diameter greater than 21 mm as the tapering attachment wall 26 reaches the bottom of the angling wall 21 . therefore the outside diameter of the tapering attachment wall 26 should range from approximately 20 mm at the exit opening 25 to approximately 22 mm at a point of adjacency to the angling wall 21 . a venturi effect is caused by this configuration which in turn accelerates the tornado effect above producing greater force of flow of solvent and , consequently , greater cleansing ability . the downward end of the device 10 [ angled cone - like extension 21 , 25 , 26 generally should be resilient and flexible . in this regard , the cone - like extension 21 , 25 , 26 and in particular , the exit opening 25 , should be made of vinyl , rubber , resilient polymers , or any combinations thereof . the tapering of the angling wall 21 , the tapering attachment wall 26 , and the exit opening 25 , and their flexibility permits easy friction - fit insertion of the device 10 into the air - flow attachment interface 33 of the hose 34 such that the outside diameter of the exit opening 25 , as it inserts into the air - flow attachment interface 33 , increases in diameter until it is securely nested into the inside diameter of the air - flow attachment interface 33 . after a user of the human - interface device 40 awakens from sleep , the user will remove the device 40 and disconnect the hose 34 from the air - flow generator 30 . the user will then re - connect the hose 34 directly to the tube - like extension 21 , 25 of the cleaning device of the present disclosure 10 . the user will then attach the base 11 to any external faucet , shower head , or similar external solvent transporting mechanism or solvent discharge mechanism . as seen in fig2 , a shower head 50 is illustrated . once the cleaning device of the present disclosure 10 is attached to the human - interface device 40 and to the shower head 50 [ for example ], water is turned on . the water will forcibly course a path through the cleaning device of the present disclosure 10 , through the hose 34 , and into and through the human - interface device 40 thereby flushing out any contaminants and build - up contained therein . in this manner , both the hose 34 and the human - interface device 40 have been cleaned . after a suitable amount of time flushing , the water stream is turned off , the cleaning device of the present disclosure 10 is removed from the human - interface device 40 , and the human - interface device 40 is suitable hung such that the hose 34 and device 40 may drain out excess water and be ready for use later that evening . the present disclosure includes that contained in the present claims as well as that of the foregoing description . although this cleaning device of the present disclosure has been described in its preferred form with a certain degree of particularity , it is understood that the present disclosure of the preferred form has been made only by way of example and numerous changes in the details of construction and combination and arrangement of parts may be resorted to without departing from the spirit and scope of the cleaning device of the present disclosure . accordingly , the scope of the cleaning device of the present disclosure should be determined not by the embodiment [ s ] illustrated , but by the appended claims and their legal equivalents . applicant [ s ] have attempted to disclose all the embodiment [ s ] of the cleaning device of the present disclosure that could be reasonably foreseen . it must be understood , however , that there may be unforeseeable insubstantial modifications to cleaning device of the present disclosure that remain as equivalents and thereby falling within the scope of the cleaning device of the present disclosure .
a human - interface cleaning device for cleaning human - interface devices commonly used for the treatment sleep apnea . the cleaning device has a solvent - receiving end which connects to a solvent - delivery source such as a faucet or shower head . at the opposite end of the cleaning device is a funnel - like shaped solvent - discharge end which is tapered at its distal end and adapted to easily friction - fit into any receiving aperture of most human - interface devices . the inner chamber of the device has one or more fins each having an angled flap at their ends . as so connected to a solvent - delivery source and to a human - interface device , the cleaning device will enhance the force of the solvent being delivered through the cleaning device and more easily and effectively clean the human - interface device to which attached .
