DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

[0027] With reference to the drawings, the invention will now be described in more detail. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood to one of ordinary skill in the art to which the presently disclosed subject matter belongs. Although any methods, devices, and materials similar or equivalent to those described herein can be used in the practice or testing of the presently disclosed subject matter, representative methods, devices, and materials are herein described.

[0028] Referring to FIG. 1, an IV line 10 can include a distal end 12 that includes a male end 14. The male end can be a male luer end. The distal end can be attached to a female end of an IV catheter extension that then would connect to a needle and cannula that is inserted into the patient with a portion of the distal end of the tubing possibly taped to the patient near the insertion site. A distal (male) end cap 16 can be used to cap the distal end of the IV tube. A proximal end 18 can be included in the IV tube and can include a female end 20. An end cap 22 can be attached to the proximal (female) end. In use, the proximal end is connected to any number of articles including IV medication through the use of other IV connectors. Other female ends, or ports such as the female end 20 can extend from any portion of the tubing 10 to create an access point for medication administration through the IV line. It is the distal end 14 that is normally subject to reduced sterility when it is disconnected from the patient without being capped, capped incorrectly, falls to the floor, or with other exposure and the like. When the IV is attached to the end cap and the end cap is attached to the strip, the IV tube can hang from the end cap and therefore does not contact the floor. This feature can prevent the IV tube from being contaminated as well as prevent tangling of the tubes themselves.

[0029] Referring to FIG. 2, an assembly 24 is attached to a strip 26. In one embodiment, the strip hangs from the IV stand for quicker availability for nurse. The strip allows an end cap 32 to be readily accessible to the nurse for use. The open end 25 of the cap can have a tear away cover 28 with a tab 30. By providing the tear away cover, the open end of the end cap is covered and sealed to help insure sterility until the nurse is ready to use the cap. The assembly can include an end cap 32 with a central opening 34 and circumferential flanges 36 that can completely or partially surround the central opening. The central opening can include a sterilization pad or swab 29 attached to the interior of the central opening so that when the end of the IV tube is received in the central opening, the end of the IV tube is sterilized with a sterilization agent.

[0030] A swivel portion of an end of an IV tube can be received into the opening defined between the housing 38 and the end cap. In one embodiment, the swivel portion of the male end is received into the housing. The male portion of a catheter would be received into the center 34 of the end cap. The inner wall 40 of the housing can include a housing sloped portion 42 that cooperates with an end cap sloped portion 43 disposed on the outer surface of the end cap so that the IV tube cannot be removed from the end cap without the end cap being removed from the strip. The IV connector can be disposed so that when attached to the end cap, the swivel portion does not extend into the area occupied by the housing sloped portion 42 in one embodiment. The housing sloped portion and end cap sloped portion can be cooperatively associated to prevent the IV tube from being removed from the end cap unless the end cap is removed from the strip.

[0031] The end cap can include a first fastening member 44 that can be received into the opening 46 in the strip. In one embodiment the diameter of the first fastening member is larger than the opening so that sufficient force is required to deform the opening to cause the end cap to be removed from the strip. The opening can be defined in the strip or in a second fastening member 48. The first fastening member can extend through the strip and be received into the second fastening member so that the end cap is secured to the strip. In one embodiment, once the end cap is removed from the second fastening member, the second fastening member cannot be replaced preventing reuse of the end cap and promoting compliance with proper IV procedures. In one embodiment, the first fastening member and second fastening member are a ball and socket assembly. In one embodiment, when the end cap is removed from the strip, the housing remains attached to the strip. In one embodiment, the housing is attached to the strip and surrounds the end cap so that when the IV tube is attached to the end cap, the IV tube cannot be separated from the end cap without the end cap being removed from inside the housing. In one embodiment, the housing cannot be removed from the strip. In one embodiment, the second fastening member is not attached to the strip and held in place when the end cap is in place. The second fastening member drops away when the end cap is removed.

[0032] In one embodiment, a one-way fastener is included in the strip allowing the end cap to be removeably attached to the strip, but not to be replaced on the strip. A rigid ring 41 can define the opening in the strip for receiving the first fastening member. A resilient ring 47 is disposed within the housing and adjacent to the end cap when the end cap is attached to the strip. When the end cap is pulled away from the strip in a direction shown as 45, the resilient member deforms inward allowing the first fastening member to be pulled through the opening and removed from the strip. When the end cap is attempted to be replaced by pushing it in a direction opposite that of 45, the resilient member contacts the rigid member and does not sufficiently deform to allow the first fastening member to be placed through the opening in the strip, thereby preventing the end cap from being reused. The rigid portion 41 can be disposed away from end 25 in relation to the resilient member 47 in one embodiment.

[0033] Referring to FIG. 3, the open end of the housing is shown. The opening as shown allows the resilient member 47 to be exposed after the end cap has been removed. The portion shown as 47, in one embodiment, is the portion of the resilient member that can deform when the end cap is pulled from the strip.

[0034] Referring to FIG. 4, the end cap is shown without the housing. The end cap is attached by a first fastening member 44 to a resilient member 47. In this embodiment, the resilient member is attached to the strip 26 so that the first fastening member does not extend through the strip. When the end cap is pulled from the resilient member, the resilient member deforms so that the end cap can be removed. The resilient member reverts generally to its original shape preventing the end cap from being reattached to the strip to deter reuse of the end cap and increase compliance with IV procedures. In one embodiment, the resilient strip is generally a conical shape.

[0035] Referring to FIG. 5, the end caps can be positioned on the strip and can hang from the IV stand 52 from a hook 54 or another hanging element. The top housing 60 is shown after the end cap has been removed. The next housing 62 is shown with the seal removed and a IV end 18 being placed on the end cap. The next housings 64 and 66 are shown with the seals in place and ready for use.

[0036] Referring to FIG. 6, in one embodiment, the strip can include opening 60a and 60b at each end that include discontinuous area 62a and 62b. the discontinuous area allowing adjacent strips to be connected to each other in a chain 64.

[0037] This invention results in a higher rate of compliance among healthcare providers in charge of intravenous line care for both central and peripheral lines. Having a higher rate of compliance among providers translates directly to a lower rate of infection, improved patient outcomes, and lower healthcare costs for facilities providing IV care. The end cap can be firmly attached to the strip and cannot be removed without sufficient effort.

[0038] By offering an end cap attached to a strip that is hung from IV poles, nurses are provided with a safer, easier, sterile alternative to the method of looping the IV lines into themselves (found very often among nurses) while offering more ease of use and ready availability of the IV line for later use. This also allows nurses to more easily organize and identify multiple IV lines, keeping drugs for more complex patients in order, which will minimize time consumption and mistakes. Not only would hanging stationary IV caps in this manner make it much easier for nurses to comply with hospital regulations, but it would also make them much more willing to do so, which is key in solving the problem of end-user compliance.

[0039] The end cap in one embodiment must be detached from its base in order for a nurse to uncap the male portion of the IV line. The actual cap portion only covers the central, thin, male catheter portion of the line, and is attached to the cap base using a ball-in-socket type of joint. The cap is unable to be removed by unscrewing it, but must be unsnapped from its base rendering it more difficult to be reused as opposed to using a new cap from the cap strip. This functionality increases compliance with IV procedures. Also, for the instances where a nurse needs a capped line away from the IV pole, it is ready and available by simply snapping the cap off of its base.

[0040] Referring to FIG. 7, the strip can include a rear portion 66 that can include a tab 70. The rear portion can be attached to the front portion 68 and affixed to the front portion when the tab is received into a tab opening 72. The housing 38 can be attached to the front portion. The end cap 32 can be attached to the rear portion. In one embodiment, the end cap is attached to the rear portion by a breakaway connection 74.

[0041] Unless specifically stated, terms and phrases used in this document, and variations thereof, unless otherwise expressly stated, should be construed as open ended as opposed to limiting. Likewise, a group of items linked with the conjunction and should not be read as requiring that each and every one of those items be present in the grouping, but rather should be read as and/or unless expressly stated otherwise. Similarly, a group of items linked with the conjunction or should not be read as requiring mutual exclusivity among that group, but rather should also be read as and/or unless expressly stated otherwise.

[0042] Furthermore, although items, elements or components of the disclosure may be described or claimed in the singular, the plural is contemplated to be within the scope thereof unless limitation to the singular is explicitly stated. The presence of broadening words and phrases such as one or more, at least, but not limited to or other like phrases in some instances shall not be read to mean that the narrower case is intended or required in instances where such broadening phrases may be absent.

[0043] While the present subject matter has been described in detail with respect to specific exemplary embodiments and methods thereof, it will be appreciated that those skilled in the art, upon attaining an understanding of the foregoing may readily produce alterations to, variations of, and equivalents to such embodiments. Accordingly, the scope of the present disclosure is by way of example rather than by way of limitation, and the subject disclosure does not preclude inclusion of such modifications, variations and/or additions to the present subject matter as would be readily apparent to one of ordinary skill in the art using the teachings disclosed herein.
