Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a disposable infusion set to prevent needle punctures. Background Art
[0002] When the patient's infusion is finished, the nurse will pull out the intravenous infusion needle. Due to hospital infection requirements, the needle is not allowed to be reinserted into the infusion bottle. Currently, most nurses will insert it into a Moffitt dropper or infusion tube. However, due to the hardness of the Moffitt dropper and infusion tube, it is very easy to get a needle stick injury during the reinsertion process. If the needle is not inserted into the Moffitt dropper or infusion tube, the needle must be held by the nurse until the infusion set is sent back to the treatment room for treatment. In this process, it is also very easy to stab yourself or others. Therefore, it is very necessary to effectively protect the needle to ensure the safety of medical staff and others.

[0017] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.
[0018] Example:
[0019] The attached drawings show a specific implementation of a disposable infusion set for preventing needle stick injuries according to the utility model. Figure 1 It mainly includes an infusion set body 1, a protective mechanism 2 fixedly connected to a bottle plug piercer 13 near the infusion set body 1, and a Figure 2 , Figure 3 The protective mechanism 2 specifically includes a left half protective shell 3 and a right half protective shell 4 that are detachably connected. In this embodiment, the tops of the left half protective shell 3 and the right half protective shell 4 are provided with symmetrically arranged threaded connectors 10, and the two threaded connectors 10 are screwed together by a nut 15. The protective mechanism 2 can be disassembled by screwing the nut 15.
[0020] A left half accommodating chamber 5 and a right half accommodating chamber are respectively provided inside the left half protective shell 3 and the right half protective shell 4. The left half accommodating chamber 5 and the right half accommodating chamber are symmetrically arranged and interconnected to form a complete accommodating chamber. The intravenous infusion needle 11 of the infusion device body 1 can be inserted into the accommodating chamber of the protective shell from the bottom.
[0021] The left half protective shell 3 and the right half protective shell 4 are also provided with symmetrical left half concave cavity 6 and right half concave cavity 7, and the left half concave cavity 6, the right half concave cavity 7, the left half accommodating cavity 5, and the right half accommodating cavity are interconnected. The left half concave cavity 6 and the right half concave cavity 7 are provided with symmetrically arranged anti-drop telescopic baffles 8, and when the intravenous infusion needle 11 is inserted, the needle handle 11a can be limited by the cooperation of the two anti-drop telescopic baffles 8 in the concave cavity.
[0022] Specifically, in the present embodiment, one end of the anti-dropout telescopic baffle 8 is elastically mounted in the protective shell by a spring, and an arc-shaped guide portion 8a is provided at the lower portion of the other end. There is a spacing between the two anti-dropout telescopic baffles 8 to facilitate the insertion of the needle handle 11a and to limit the inserted needle handle 11a to prevent it from dropping out.
[0023] A sponge 14 is also provided in the housing cavity of the protective shell. The sponge 14 can be provided in one piece and can be placed on the top of the complete housing cavity formed by the left half housing cavity 5 and the right half housing cavity, or two sponges 14 can be used and fixedly provided on the top of the left half housing cavity 5 and the right half housing cavity, respectively. The sponge 14 is used for the needle tip 11b of the intravenous infusion needle 11 to be inserted, and plays a protective role.
[0024] In addition, in this embodiment, a connecting line 9 is provided on the left half protective shell 3 or the right half protective shell 4 of the protective mechanism 2, and the other end of the connecting line 9 is connected to the infusion tube 12 below the bottle stopper piercer 13.
[0025] When the utility model is used, after the intravenous infusion needle 11 is pulled out after the infusion is completed, the nursing staff holds the needle handle 11a, and inserts the intravenous infusion needle 11 from the bottom into the accommodating cavity of the protective mechanism 2, and the needle handle 11a then enters the concave cavity. In the process of pushing the intravenous infusion needle 11 into place as a whole, the needle handle 11a is first inserted between the two anti-dropout telescopic baffles 8 along the arc-shaped guide portion 8a, and the anti-dropout telescopic baffle 8 is reset under the action of the spring, and the inserted needle handle 11a is limited to prevent it from falling out downward, thereby achieving the fixation of the entire intravenous infusion needle 11. The design of the anti-dropout telescopic baffle 8 allows the intravenous infusion needle 11 to be inserted only, but not pulled out, which greatly improves safety. If the intravenous infusion needle 11 needs to be removed, the protective mechanism 2 can be quickly disassembled by screwing the top nut 15, and the internal sponge 14 can also effectively prevent needle punctures during the process of removing the intravenous infusion needle 11, playing a secondary protection role. The infusion set of the utility model can timely and effectively protect the pulled-out intravenous infusion needle, greatly improving the safety of use, and after inserting it into the protection mechanism 2 and fixing it, Figure 4 , the intravenous infusion needle 11 and the bottle stopper puncture device 13 can be placed into the sharps box by cutting only once along the dotted line in the figure, which is safer and more convenient than the traditional operation that requires cutting the needles at two places separately.
[0026] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical solution of the utility model should be included in the protection scope of the utility model.
