AI Technical Summary
Existing syringes can easily cause fingers to cross the needle when removing the shield, increasing the risk of stabbing and leading to safety accidents.
A stabbing-proof syringe is designed. By setting a connecting ring on the syringe, the connecting ring is connected to the syringe and the shield through hot melting point welding. The operator simply needs to remove the connecting ring to remove the shield to prevent his fingers from crossing the needle.
The design can remove the shield without fingers passing through the needle, which significantly improves operating safety, avoids stab injuries, and achieves the purpose of preventing stab injuries.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical syringes, and more specifically relates to a stab-proof syringe. Background Art
[0002] A syringe is a common medical device used for subcutaneous injection and intravenous infusion. It mainly uses a needle to extract or inject gas or liquid. Generally, the needle at the front end of the syringe is sharp. In order to avoid accidental punctures, a protective cover is placed on the needle. When the syringe is used, the nurse or doctor will first remove the protective cover during operation. However, during the actual operation, the nurse's finger will pass over the needle when removing the protective cover. If the nurse is not careful, the finger will not pass the needle enough and the needle will puncture the needle, resulting in a medical accident. Therefore, an anti-puncture syringe is proposed. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a stab-proof syringe, which can realize the removal of the protective cover without the need for fingers to pass over the needle, thereby improving safety, avoiding safety accidents, and achieving the purpose of stab-proofing.
[0004] The utility model discloses an anti-stab-injury syringe, comprising a syringe, a piston rod and a needle; the piston rod is movably installed in the syringe, and a sealing piston is arranged at one end of the piston rod, and the sealing piston abuts against the inner wall of the syringe to form a seal; the needle is arranged at one end of the syringe away from the piston rod, and the needle is communicated with the syringe; and a shield is also included, which is sleeved on the needle and detachably connected to the lower end of the syringe.
[0005] As a further improvement of the utility model, it also includes a connecting ring, the upper end of the connecting ring is connected to the lower end of the syringe; the lower end of the connecting ring is connected to the upper end surface of the shield.
[0006] As a further improvement of the utility model, the connecting ring, the syringe and the shield are all connected by hot-melt spot welding.
[0007] As a further improvement of the utility model, the connecting ring is an open ring structure.
[0008] As a further improvement of the utility model, a handle is provided at one end of the connecting ring, and a plurality of convex strips are provided on the outer wall of the handle.
[0009] Compared with the prior art, the advantages of the present invention are:
[0010] In the utility model, the protective cover can be dropped and removed by only pulling out and disassembling the connecting ring, and there is no need to pass fingers over the needle to pull out the protective cover, which is safer and achieves the purpose of preventing puncture injuries.

[0016] Specific embodiment 1: Please refer to Figure 1-3 A stab-proof syringe comprises a syringe 1, a piston rod 2 and a needle 3; the piston rod 2 is movably installed in the syringe 1, and a sealing piston is arranged at one end of the piston rod 2, and the sealing piston abuts against the inner wall of the syringe 1 to form a seal; the needle 3 is arranged at one end of the syringe 1 away from the piston rod 2, and the needle 3 is communicated with the syringe 1;
[0017] The syringe 3 also includes a shield 4 and a connecting ring 5. The shield 4 is sleeved on the needle 3. The upper end of the connecting ring 5 is connected to the lower end of the syringe 1 by hot-melt spot welding; the lower end of the connecting ring 5 is connected to the upper end surface of the shield 4 by hot-melt spot welding; at the same time, the connecting ring 5 is an open-loop structure. When using the syringe, the connecting ring 5 is pulled out to break the spot welding connection between the connecting ring 5, the syringe 1 and the shield 4, so that the shield 4 will fall off, and the purpose of disassembly is achieved without the need to pull the shield 4 over the needle 3 with fingers; and a handle 6 is provided at one end of the connecting ring 5, and a plurality of convex strips 7 are provided on the outer wall of the handle 6; the handle 6 is convenient for the operator to pinch the connecting ring 5 and pull it to break it, and the operation is simpler. At the same time, the setting of the convex strips 7 can increase the friction when the operator pinches the handle 6, avoid slipping when pulling the connecting ring 5, and ensure that the operator can normally disassemble the connecting ring 5.
[0018] Working principle: In the utility model, when using the syringe, the operator only needs to pinch the handle 6 at one end of the connecting ring 5 and pull the handle 6, causing the hot-melt connection between the connecting ring 5, the syringe 1 and the shield 4 to break, so that the shield 4 falls off by itself. There is no need for the operator to go over the needle 3 to disassemble the shield 4, which is safer and achieves the purpose of preventing puncture injuries.
[0019] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
