Embodiment 1

[0024] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, the present invention includes an upper part 1 and a lower part 2, the upper part 1 is socketed with the needle holder 5, the lower part 2 is rotatably connected with the upper part 1, and the upper part 1 has an upper and lower A hollow square cylinder with a through hole. The lower part 2 is a hollow square cylinder with an open top and a closed bottom. The bottom ends of the two opposite sides 1a and 1b of the upper part 1 are each provided with a vertically extending downwards. Out of the legs 10, the two legs 10 are respectively provided with a shaft hole 12, and the two opposite sides 2a, 2b of the lower part 2 are respectively provided with an outwardly protruding shaft 20, and the two shafts 20 coaxial, the shaft 20 is rotatably connected to the shaft hole 12, and the shaft hole 12 is a round hole. The inner through hole of the upper part 1 is provided with four vertical ribs 11 uniforml...

Embodiment 2

[0027] like Image 6 , Figure 7 , Figure 8 , Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that: the shaft hole 12 is an oblong hole, the shaft 20 is closely matched with the shaft hole 12, and the outer edge of the annular flange 3 is provided with Circumferential vertical wall 4, the peripheral vertical wall 4 is socketed with the outer peripheral wall of the lower part of the syringe, so that the upper part 1 and the needle holder 5 are also securely socketed synchronously, and it is more difficult to fall off. At the same time, the annular protrusion The rim 3 and the peripheral wall 4 form a groove structure. After the injection operation is completed, the upper part 1 is sleeved and fixed on the needle holder 5, even if the needle is not accurately inserted into the through hole. Inside, the needle is still limited within the scope of the groove and will not prick your fingers. When packing and storing, the shaft 20 is located at th...

Abstract

A high-safety needle destroying unit for injector has an upper part which is a hollow cylindrical body with a central through hole and sleeve-jointed with needle holder, and a low part which is a hollow cylindrical body with open top end and closed bottom end, and connected with said upper part in rotary mode.

Description

technical field [0001] The invention relates to a needle damage safety device of a syringe. Background technique [0002] Syringes have always been widely used and indispensable medical devices. However, after the injection, the traditional disposable syringe is discarded without damage. If it is recycled by unscrupulous people, it will cause serious safety and health risks, especially when the undamaged needle is used for injection again without disinfection. , the consequences are even more serious; in addition, when medical waste disposal personnel are disposing of discarded syringes, they are often stabbed due to the loosening of the needle cover of the syringe, resulting in infection with blood-borne diseases. In view of the above-mentioned defects of traditional syringes, there are various needle damage safety devices for syringes, but these safety devices are generally complex in structure, cumbersome in manufacturing and assembly process,...
