Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a needle cap for a syringe that prevents puncture wounds. Background Technology

[0002] Syringes are widely used tools in medical treatment and medical education, but needlestick injuries are common during their use, posing a major occupational hazard to healthcare workers and becoming a significant route of bloodborne infection. Nurses face an even higher risk of bloodborne infection due to the frequent injection and puncture procedures they perform.

[0003] Although the use of safety devices can significantly reduce the incidence of needlestick injuries, the design of traditional syringe needle caps, which are widely used in my country, has defects, resulting in their low usage rate. Traditional needle caps are fixed to the needle plug by friction, and a large force is required to remove them, which may lead to rebound force and increase the risk of needlestick injuries. In addition, the opening of the needle cap is small, making it difficult to align with the needle tip when reattaching, further increasing the possibility of the finger being pricked by a needle. Utility Model Content

[0004] The purpose of this invention is to provide a needle cap for a syringe that prevents punctures, thereby solving the problems of small openings and difficult removal of traditional needle caps.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A needle cap for a syringe designed to prevent punctures is provided, comprising a locking area and a fixing area. The locking area is provided with several zipper-like structures, each of which contains a needle plug inside the locking area. Each of which contains a push block outside the locking area contains a push block, with the needle plug and the push block corresponding to each other and engaging with each other. The fixing area contains several ejector pin sleeves, and the fixing area has several openings.

[0007] As a preferred embodiment of a syringe needle cap designed to prevent punctures, a skirt is provided at the front edge of the locking area, and a limiting hole is provided in the middle of each of the plurality of ejector pin sleeves.

[0008] As a preferred embodiment of a syringe needle cap designed to prevent punctures, the end of the needle plug is inclined inward.

[0009] As a preferred embodiment of a syringe needle cap designed to prevent punctures, both the snap-fit ​​area and the fixing area have smoothed edges.

[0010] The beneficial effects of this utility model are:

[0011] 1. The zipper-designed needle cap reduces the force required to remove the needle shaft and tip, making the operation easier. The open design of the needle cap solves the problem of high insertion and withdrawal force caused by traditional airtight designs, reducing the operating resistance caused by airtightness. This makes it easier for medical staff to operate, while also speeding up the operation and improving work efficiency.

[0012] 2. The needle sleeve protects the needle tip from exposure while ensuring it is not contaminated by the outside world, effectively protecting the user's safety and maintaining the cleanliness and sharpness of the needle tip. Multiple needle sleeves can be used multiple times, making the operation more efficient and safer, and significantly enhancing protective measures in the medical environment.

[0022] like Figure 1-2 As shown, this utility model provides a technical solution: a needle cap for an anti-puncture syringe, including a locking area 1 and a fixing area 2. The edges of both the locking area 1 and the fixing area 2 are smoothed. Four zipper-like structures 3 are equidistantly arranged around the center of the locking area 1. A needle plug 4 is slidably connected to each of the zipper-like structures 3 inside the locking area 1. The end of the needle plug 4 is inclined inward to adapt to the shape of the needle shaft. A push block 5 is slidably connected to each of the zipper-like structures 3 outside the locking area 1. The needle plug 4 and the push block 5 are connected to each other on the zipper-like structures 3 in a one-to-one correspondence. Three ejector sleeves 6 are arranged sequentially on the rear side inside the fixing area 2. The fixing area 2 has openings 7 symmetrically opened at the top and bottom to solve the problem of high insertion and removal force caused by the airtight design of traditional needle caps, making the needle cap easier to pull out and put on, making it easier for medical staff to operate. A skirt 8 is provided at the front edge of the locking area 1. A limiting hole 9 is opened in the middle of each of the three ejector sleeves 6 to facilitate fixing the needle tip in the ejector sleeve 6 and protect the needle tip from contamination.

[0023] Working principle: In use, grasp the skirt 8 of the snap-fit ​​area 1, then insert the needle tip into the limiting hole 9 of the ejector sleeve 6 in the fixing area 2, and then adjust the position to insert the needle shaft into the needle plug 4. At this time, push the push block 5 forward to push the needle plug 4 forward along the zipper structure 3, so that the needle plug 4 and the needle shaft fit tightly against the fixed needle shaft. When it is necessary to remove the needle shaft and needle tip, push the push block 5 backward to push the needle plug 4 backward along the zipper structure 3, so that the needle plug 4 and the needle shaft are separated. At the same time, the opening 7 on the fixing area 2 makes it easier to remove and put on the needle cap. When the needle is removed, the corresponding ejector sleeve 6 is also taken out with it to prevent the needle from being contaminated by the outside when it is removed. When the needle is in use, push the syringe gently to blow out the ejector sleeve 6 with the air in the syringe. When it is necessary to store temporarily, insert the needle shaft and needle tip into the needle plug 4 and the remaining ejector sleeve 6 in sequence and push the push block 5 to fix them. Repeat the above steps when using again.
