However, due to the structural problems of ordinary disposable syringes, some operators have used them twice or multiple times, and users' illegal operations have caused cross-infection. In order to prevent artificial recycling and reuse, people set up self-destruct devices on disposable ordinary syringes.
However, although the self-destructing disposable syringes can prevent the reuse of the syringes, the exposed needles of the syringes will cause a lot of inconvenience in the collection, transportation, and processing of the discarded syringes after use, and it is still possible to stab medical staff and others. Its related personnel, causing cross-infection of viruses and bacteria

Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 As shown, the safety injection needle includes a needle used in conjunction with each other, a needle sheath 1 , a needle seat 2 and a safety needle sheath 3 .
[0022] The body of the safety needle cover is a sleeve 9, and a hook 7 is provided at the bottom of the sleeve 9, and the bottom edge of the sleeve 9 is connected with the cylinder 5 through a shrapnel 6 to ensure that the sleeve 9 can be positioned 180 degrees above and below the cylinder 5. The position of ° moves elastically, and a clamping hole 14 is set on the cylinder 5, which is used to clamp with the hook 7 to fix the sleeve 9; the sleeve 9 is used to cover the needle and protect the needle. A square sheet 4 for holding the needle is provided, and the square sheet 4 is preferably arranged on the middle inner wall...

The invention discloses a safe entry needle comprising a needle head, a needle head jacket, a needle head seat and a safe needle sleeve, wherein the safe needle sleeve comprises a sleeve used for sleeving the needle head, and a cylinder and a slice used for locking the needle head are arranged on the sleeve; the needle head seat comprises a needle head connecting end, a safe needle sleeve connecting segment and an inner conical joint end, which are integrally connected; the needle head jacket is sleeved on the needle head connecting end; the cylinder is connected with the safe needle sleeve connecting segment; the inner conical joint end is cooperatively connected with an outer needle cylinder connecting end. The universal safe entry needle is simple and reasonable in structure, can not be used secondarily, is free of cross infection, unlikely to scratch people, easy to manufacture, low in cost, safe to use and strong in universality, and various of injectors can be matched with safe needle sleeves, so that the practicability is good.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a safety injection needle. Background technique [0002] Safe self-destructing disposable syringes are widely used in the medical field to avoid virus cross-infection caused by using unhygienic syringes. However, due to the structural problems of ordinary disposable syringes, some operators have used them twice or multiple times, and users' illegal operations have caused cross-infection. In order to prevent artificial recycling and reuse, people set up self-destruct devices on disposable ordinary syringes. . However, although the self-destructing disposable syringes can prevent the reuse of the syringes, the exposed needles of the syringes will cause a lot of inconvenience in the collection, transportation, and processing of the discarded syringes after use, and it is still possible to stab medical staff and others. Its related personnel cause cross-infection of viruses...
