as shown in the exemplary drawings for the purposes of illustration , an embodiment of a support device made in accordance with the principles of the present invention , referred to generally by the reference numeral 10 , is provided for support of a standard ( non - ambulatory type ) fluid set and an infusion pump of a fluid delivery system . more specifically , as shown in fig1 ( a )-( d ) and fig2 the support device 10 includes a generally rectangular rigid body 11 which is preferably formed of rigid polymeric material or other lightweight material such as wood , metal alloy , etc . the body 11 is adapted to receive and retain an infusion pump 15 and a fluid delivery set 16 of a fluid delivery system . the body 11 forms a pump compartment 12 adapted to receive the standard infusion pump 15 , a container compartment 13 adapted to partially receive a soft bag 17 from the standard fluid set 16 , a tube channel 14 adapted to receive the tube 18 of the standard fluid set 16 , and a pinch clamp compartment 19 adapted to receive a pinch valve 20 located on the tube 18 of the fluid set 16 . the support device 10 also includes a plurality of fastening elements which are adapted for use in securing the fluid delivery system to the rigid support body 11 during use . these elements include a lid clamp 21 which is permanently affixed to a lid clamp extension 22 , a securing strap 23 , a saddle bracket 24 which is secured in a flush mount position in the bottom 25 of container compartment 13 , and a pump locking mechanism ( not shown ) formed as a part of the base 26 of the body 11 . the body 11 is also integrally formed with an elevated section 27 which cooperates with a similarly elevated section 28 to form the tube path 29 . elevated section 27 also forms part of the pump compartment 12 . finally , if desired , an extendable leg 30 may be located in elevated section 27 so as to be flush therewith when the leg 30 is in its retracted position , and to be perpendicular therewith and parallel to base 26 when in its extended position . as best shown in fig1 ( a )-( c ), the tube channel 14 of the support device 10 extends around approximately two thirds of the circumference of the body 11 . the tube channel 14 is generally u - shaped in cross - section and includes a base 31 , a front wall 32 , and a back wall 33 . the tube channel 14 is essentially a channel between the front and back portions 34 and 35 , respectively , of the body 11 , and extends from entrance opening 36 across the top and partially down the opposite side of body 11 to exit opening 37 . slightly above exit opening 37 , the channel 14 is interrupted by the pinch clamp compartment 19 which is sized to receive the standard type pinch valve 20 commonly attached to the tubing 18 of the fluid delivery set 16 . the pinch clamp compartment 19 is formed by a cut out section of body 11 , and is sufficiently large to allow the pinch clamp 20 ( see fig2 ) to rest therein when the tubing 18 is located in the tube channel 14 . the channel 14 is designed to allow accommodation of the tubing 18 of the fluid set 16 even though slight variation in tubing length may occur between sets 16 . this is possible due to the channel 14 being formed to a sufficient depth to allow some &# 34 ; snaking &# 34 ; of the tube 18 when necessary for the channel 14 to be able to accommodate its entire length . further , the channel 14 is also designed with a lip 38 which retains the tubing 18 therein once place , even though some &# 34 ; snaking &# 34 ; may occur . as best illustrated in fig1 ( c ), the forward sloping section 39 of the body 11 causes the exit opening 37 of the tube channel 14 to be positioned somewhat centrally over the pump compartment 12 . this is advantageous in that it allows the tubing 18 of the fluid delivery set 16 to exit channel 14 at exit opening 37 in the proper position for reception into the hinged pump arm 40 of the pump 30 . the support device 10 of the present invention is adapted to be able to receive and secure several different types of containers commonly used with standard fluid delivery sets 16 . for example , as best shown in fig1 ( c ) and fig3 container compartment 13 is recessed below front portion 34 of body 11 , and shaped to receive a portion of a rigid blow molded type plastic bottle 41 , with the assistance of the saddle bracket 21 . alternatively , as best shown in fig1 ( a )-( c ), the body 11 includes a lid clamp extension 22 on its front portion 34 which extends above the container compartment 13 and includes a lid clamp 21 oriented to receive the lid 42 of a soft flexible bag 17 . the lid clamp 21 operates to secure the lid 42 of bag 17 in its proper position to allow the bag 17 to be properly located within container compartment 13 . also , and more importantly , the lid clamp 21 operates to prevent the sudden application of an external pressure from inadvertently bursting the lid 42 open during use , such as may occur if the support device 10 is inadvertently dropped . as best shown in fig1 ( a ) and 1 ( c ), the lid clamp 21 includes a inner clamp jaw 44 which is permanently attached to the lid clamp extension 22 , and permanently attached through hinge 45 to an outer clamp jaw 46 . a strap 47 including a hook and pile type fastener 48 , is attached to jaws 44 and 46 . the strap 47 allows the clamp 21 to be securely fixed in a closed position . when in the closed position , the jaws 44 and 46 of the clamp 21 form a circular opening for receiving the mouth and lid 42 of the bag 17 . the circular opening of the inner clamp jaw 44 forms an inner lip channel ( not shown ), and similarly , the outer clamp jaw 46 forms an outer lip channel ( not shown ), which will receive the circumferential edges of mouth and lid 42 of the bag 17 . also , since the lid 42 generally includes an opening tab 49 thereon , the outer clamp jaw 46 is formed with an opening 50 through which the tab 49 can extend when the clamp 21 is closed about the lid 42 . the lid clamp 21 can be positioned above container compartment 13 a sufficient distance to allow the accommodation of the desired size of bag 17 . for example , as shown in fig2 the lid clamp extension 22 may be located adjacent the body 11 to allow the container compartment 13 to accept and properly position a bag 17 of standard 600 ml . volume . alternatively , as shown in fig4 the lid clamp extension 18 can be located a sufficient distance from body 11 to allow room in container compartment 13 to accept a bag 17 of the standard 1000 ml . volume . a detailed description of the support device 10 of the present invention is given in co - pending application ser . no . 679 , 886 , filed apr . 3 , 1991 , and is incorporated herein by reference . as best shown in fig5 the carrying case 51 is formed generally to conform to the exterior shape of the support device 10 and includes semi - rigid foam lined walls 52 and cover 53 . the cover 53 of the case 51 includes a visual access opening 54 , covered with a clear plastic panel 55 , which allows visual access to the bag 17 when mounted to the support device 10 for use . front 53 of the case 51 also includes a control panel opening 56 which allows visual and physical access to the control panel 57 and display 58 of the pump 30 . the opening 54 is covered by a flap 59 which is sized so as to cover the entire opening 54 in a protective manner . the flap 59 can include an opening tab 60 and a fastening means such as hook and pile fasteners 61 . control panel opening 56 also includes a flap 62 sized to completely cover the opening 56 to protect the pump 15 . flap 62 may also include an opening tab 63 and hook and pile type fastener 64 . further , flap 62 may also include a semi - rigid protection panel ( not shown ) which will supply added protection against accidental control panel activation , or damage to the pump 15 , due to an inadvertent blow to the case 51 . the case 51 can include a carrying strap for allowing the case to be carried on the shoulder , back or around the waist of the patient while ambulatory . as shown in fig6 the case 51 further includes a tube outlet 65 to allow tubing 66 ( see fig3 ) exiting the pump 15 to pass outside of the case 51 and be attached to the patient . the case 51 opens and closes in a &# 34 ; clam - shell &# 34 ; fashion , and may be secured in its closed position in any well known manner , such as by zipper 67 extending around the majority of the case &# 39 ; s perimeter . the case 51 as described above is described in more detail in co - pending u . s . application ser . no . 679 , 886 filed apr . 3 , 1991 which is incorporated herein by reference . the case 51 of the present invention further includes an extension 43 which allows the case 51 to be adapted to the particular size necessary to accommodate the support device 10 in instances where the lid clamp extension 22 has been extended away from the rigid body 11 to accommodate a large bag 17 of a fluid delivery set 16 . as shown in fig5 through 7 , the top of case 51 is formed with an opening 73 therethrough which is adapted to allow the lid clamp extension 22 to extend therethrough when in its extended position holding an enlarged bag 17 of a standard fluid set 16 . adjacent the opening 73 in diametrically opposed positions , are front side flap 74 and back side flap 75 . also adjacent opening 73 , in a position aligned with the side surfaces of the bag 51 is a central flap 76 . flaps 74 and 75 are of a length which is substantially equal to the extension length of the lid clamp extension 22 of the support device 10 . the central flap 76 is of a length which approximates the distance around the perimeter of the front and back side flaps 74 and 75 respectively . when there is no need for extending the pack 51 , e . g . when the lid clamp extension 22 is in the non - extended position relative to rigid body 11 , and a small bag 17 is located in the support device 10 , the front and back side flaps 74 and 75 are folded over the openings 73 and the central flap is then extended over the folded front and back side flaps 74 and 75 until the end 82 of the central flap 76 extends a sufficient distance around the side of the case 51 to allow end fastener 83 to attach with the closed position fastener 80 on the case 51 . when it is necessary to extend the case 51 to accommodate an extended lid clamp extension 22 and large bag 17 , e . g . when lid clamp extension 22 is in its extended position relative to rigid body 11 for purposes of receiving a large bag 17 , the front and back side flaps 74 and 75 respectively are extended vertically in the manner shown in fig9 and the front and back side flap fasteners 78 and 79 respectively are folded inwardly so as to rest on top of the lid clamp extension 22 . the central flap 76 is then extended over the lid clamp extension 22 and the central flap fastener 77 engages with the front and back flap fasteners 78 and 79 respectively . extension of central flap 76 is continued until the end fastener 83 thereof engages with the open position fastener 81 located on the side of the case 51 . in this position , the support device and the bag 17 are completely enclosed within the extension 43 of the case 51 . referring now to fig3 the method of attachment of a fluid delivery set 16 including the rigid bottle 41 , and a pump 15 to the support device 10 of the present invention is described as follows . the pump 15 is inserted into pump compartment 12 until it is locked in position by the pump locking mechanism ( not shown ). the saddle bracket 24 is lifted to its &# 34 ; pop - up &# 34 ; position and the bottle 41 is inserted into the container compartment 13 until tubing 18 thereof can extend into the tube path 29 . in this position , the bracket 24 secures the mouth and lid 68 of the bottle 41 against lateral movement . the strap 23 is then secured over bottle 41 to prevent its escape from the compartment 13 . the tube 18 is then grasped and forced into entrance opening 36 of tube channel 14 and drawn the entire length of channel 14 until the pinch valve 20 is reached . the pinch valve 20 is then adjusted along tubing 18 until it is oriented properly to be received in pinch valve compartment 15 . tubing 18 is then extended through the remainder of tubing channel 14 and allowed to extend beyond exit 37 . next , the drip chamber 69 is inserted into the open pump arm 40 of the pump 15 and pump tubing 70 is passed around the pump roller 71 until the retention ring 72 is properly positioned in a slot ( not shown ) within the arm 40 in such a manner as will cause the tube 70 to be stretched over the roller 71 of the pump 15 when the arm 40 is moved to its closed position . the hinged pump arm 40 is then rotated into its closed and operating position and the outlet infusion tube 66 is extended away from the pump arm 40 toward the patient . the support device 10 may then be inserted into the carrying case 51 with the infusion tube 66 extending through the tubing outlet opening 65 . alternatively , a fluid delivery set 16 including a soft bag 17 may be attached to the support device 10 in an manner similar to that described above with respect to the rigid bottle - type of fluid infusion set 16 , except that the saddle bracket 24 is not used , and instead , the lid 42 of the bag 17 is inserted into the lid clamp 21 to be securely clamped in place on the body 11 . similarly , a fluid infusion set 16 including a burette type container can be positioned in the support device 10 in a manner similar to that described above with the saddle bracket 24 being first rotated to its &# 34 ; snap up &# 34 ; position and the burette being placed in the bracket 24 . with each type of fluid infusion set 16 , if desired or necessary , the strap 23 may be used to secure the container and the container compartment 13 . although not shown , other standard fluid sets 16 , such as spike sets , etc . can be similarly used with the support device 10 of the present invention . when the fluid infusion set 16 and pump 30 are properly attached to the support device 10 , the entire device can then be inserted into a case 51 to simplify carrying the system during ambulatory use by the patient . as described above , the extension 43 of case 51 can be moved to its open position should a large bag 17 which requires the extension of the lid extension clamp 22 be presently attached to the support device 10 . it will be apparent from the foregoing , while particular embodiments of the invention have been illustrated and described , various modifications can be made thereto without departing from the spirit and scope of the present invention . accordingly , it is not intended that the invention be limited , except as by the appended claims .
