The present disclosure relates to a patient care equipment support, and more particularly relates to a patient care equipment support, such as an IV rack, to support IV containers and infusion management equipment. In critical care situations, a patient care equipment support, such as an IV rack, is supported in close proximity to a patient in order to supply the patient with multiple fluids that may be required by the patient's condition. Such fluids may, for example, include antibiotics, nutrients and the like. In some critical situations, as many as twelve to fifteen IV infusions may be required. The present invention comprises one or more of the following features or elements in the appended claims or combinations thereof. A patient care equipment support comprises an equipment supporting portion configured to support patient care equipment, and at least one member rotatably coupled to the equipment supporting portion. The at least one member may comprise an arm pivotally coupled to the equipment supporting portion to support one or more items of patient care equipment. Illustratively, the arm is configured to support at least one IV container. In some embodiments, the at least one member may comprise a pair of arms pivotally coupled to the equipment supporting portion near opposite ends thereof. Alternatively, the at least one member may comprise a roller bumper rotatably coupled to the equipment supporting portion and having a peripheral portion extending horizontally beyond the equipment supporting portion. In some embodiments, the at least one member comprises a pair of roller bumpers rotatably coupled to the equipment supporting portion near the opposite ends thereof. The equipment supporting portion may defines a recess, and each arm may be configured to move between a retracted position within the recess and an extended position outside the recess. Illustratively, each arm has a plurality of hook portions spaced therealong to support a plurality of IV containers. The plurality of hook portions may be spaced at equal increments along the length of the arms. Each hook portion may comprise a disc having a circular, elliptical, oval or non-round cross section. Each arm may have a plurality of outwardly extending portions, with each outwardly extending portion supporting a hook portion at a distal end thereof. Illustratively, the hook portion extends above and below the outwardly extending portion in a common plane. The equipment supporting portion may include an upper horizontal member, a lower horizontal member and a pair of horizontally spaced vertical posts extending between the upper and lower members near the opposite ends thereof. Illustratively, the arms are pivotally coupled to the respective posts. Each arm may include a collar portion having a bore configured to receive one of the posts and a cantilevered portion extending outwardly. Illustratively, the cantilevered portions each has a plurality of hook portions spaced therealong to support a plurality of IV containers. The bore in the collar portion may be sized to provide a frictional engagement between the collar portion and the associated post. Illustratively, each post has a circumferential groove positioned below the collar portion of the respective arm for receiving a retaining ring therein. In some embodiments, the collar portion is held between two retaining rings, one above and one below the collar portion. A spring, such as a wave washer, may be held in a state of compression between each collar portion and the associated retaining ring to provide a rotational drag on the respective arm. Illustratively, the arms are located near the upper horizontal member. The upper and lower horizontal members may define a space therebetween configured to house infusion management equipment. The lower horizontal member may be configured to form a shelf or ledge to support infusion management equipment. In some embodiments, the equipment supporting portion may include a third vertical post extending between the upper and lower horizontal members and located between the two horizontally spaced vertical posts. The third vertical post may be adapted to support infusion management equipment. Illustratively, the upper horizontal member may have a pair of roller bumper-receiving spaces near the opposite ends thereof. The roller bumpers may each have at least a portion thereof received in a respective one of the roller bumper-receiving spaces in the upper horizontal member. The equipment support may include a coupler extending downwardly from the equipment supporting portion, and configured for receipt in a patient support, such as a hospital bed, or a support structure, such as a service column. The coupler may have an upper tapered portion, a lower tapered portion and a generally cylindrical intermediate portion disposed between the upper and lower tapered portions. Although the illustrative patient care equipment support disclosed herein comprises an IV rack, the patient care equipment support may very well be configured to support any one or more of the following: heart monitoring equipment, medical gas delivery equipment, equipment monitors, patient monitors, defibrillators and the like, many of which are directly connected to a patient via lines or tubes. Features of the present disclosure will become apparent to those skilled in the art upon consideration of the following detailed description of illustrative embodiments exemplifying the best mode of carrying out the present disclosure as presently perceived. The detailed description particularly refers to the accompanying figures, in which: For the purposes of promoting an understanding of the principles of the present invention, reference will now be made to a number of illustrative embodiments shown in the accompanying drawings and the following description thereof. The coupler 102 includes an upper tapered portion 104, a lower tapered portion 106 and a generally cylindrical intermediate portion 108 disposed between upper and lower tapered portions 104, 106. The upper tapered portion 104 varies in diameter from a large diameter to a small diameter in a downward direction. Likewise, the lower tapered portion 106 varies in diameter from a large diameter to a small diameter in downward direction. Illustratively, the small diameter of the upper tapered portion 104 is equal to or larger than the large diameter of the lower tapered portion 106. The diameter of the cylindrical intermediate portion 108 is equal to or smaller than the small diameter of the upper tapered portion 104 and equal to or larger than the large diameter of the lower tapered portion 106. The two stage coupler 102 facilitates transfer of the equipment support 20 between a support structure having an upper tapered socket (not shown) for receiving the upper tapered portion 104 of the coupler 102 when the equipment support 20 is supported by the support structure and the hospital bed 22 having a lower tapered socket 52 for receiving the lower tapered portion 106 of the coupler 102 when the equipment support 20 is supported by the hospital bed 22. The support structure may comprise a service column, a radial arm, a floor-supported stand, a wheeled car, a headwall, a wall of a hospital room and the like. The upper socket has an outwardly opening slot to allow the support structure to pull away from the equipment support 20 after the equipment support 20 is firmly seated in the lower socket 52 and the upper socket is lowered to a position below the upper portion 104. PCT international application publication no. WO 2004/082553 published Sep. 30, 2004, discloses an illustrative service column and is incorporated by reference herein. The hospital bed 22 illustratively includes a lower frame 30 supported on casters 32, an upper frame 34 supported above the lower frame 30 for movement relative to the lower frame 30 between raised and lowered positions, a deck 36 supported above the upper frame 34, and a mattress 38 supported by the deck 36. An elevation adjustment mechanism 40 connects the upper frame 34 to the lower frame 30. The elevation adjustment mechanism 40 may be driven by a suitable actuator to cause the upper frame 34 to move relative to the lower frame 30. The upper frame 34 includes a head-end frame member 42 configured to extend transversely along the head end of the upper frame 34 beyond the outer periphery of the deck 36. The head-end frame member 42 supports push handles 44 and rolling bumpers 46. A transversely extending rail 48 is supported by the frame member 42. A carriage 50, carrying the lower socket 52, is coupled to the rail 48 for movement along rail 48. The lower socket 52 has an upwardly opening frustoconical bore for receiving the lower tapered portion 106 of the coupler 102 when the equipment support 20 is supported by the hospital bed 22. The frustoconical bore in the lower socket 52 varies in diameter from a large diameter to a small diameter in a downward direction. The carriage 50 is lockable at any one of a plurality of locations along the rail 48. Illustratively, PCT international application publication no. WO 2005/037164 discloses such hospital bed and is incorporated by reference herein. Although the illustrative patient care equipment support in As shown in As shown in Referring to The outside posts 114, 116 extend between the flange portions 132 of the upper horizontal member 110 and the end portions 164, 166 of the lower horizontal member 112, respectively. The central post 118 extends between the central portion 142 of the upper horizontal member 110 and the central portion 172 of the lower horizontal member 112. As shown in Referring to Each hook portion 190 has portions 192, 194 that extend above and below the associated outwardly extending portion 188 in a common plane. The extension of hook portions 190 above and below the associated outwardly extending portions 188 improves the retention of the IV bags 24 and reduces the risk of accidental removal of the IV bags 24. The arms 174, 176 are symmetrical about a horizontal plane bisecting the vertical dimension of the arms 174, 176. This allows the same part to be used at both ends of the equipment support 20, which is a cost advantage. Alternatively, as shown in Reference is made to U.S. provisional patent application Ser. No. 60/592,617 filed Jul. 30, 2004, which discloses an equipment support having hook portions only at the ends of the rods, instead of having a plurality of hook portions 190 along the respective lengths of the rods 174, 176 as shown in Although the invention has been described in detail with reference to certain illustrative embodiments, variations and modifications exist with the scope and spirit of this disclosure as described and defined in the following claims. |
