Embodiment 1

[0031] Such as Figure 1~2As shown, this embodiment provides a syringe needle protection device, which includes a syringe fixing sleeve 1, a needle protection sleeve 2 and a locking device. The syringe fixing sleeve 1 includes a sliding connection sleeve 3 and a support fixing part. The support and fixing part is fixedly connected, and the other end of the sliding connection sleeve 3 is sleeved on one end of the needle protection sleeve 2 and is slidably connected with the needle protection sleeve 2. The other end of the needle protection sleeve 2 is provided with a needle inlet and outlet 4, and the needle protection sleeve 2 is provided with a needle inlet. One end of the outlet 4 is fixed with an elastic support seat 5, and one end of the syringe equipped with a needle passes through the sliding connection sleeve 3 and extends into the needle protection sleeve 2. The supporting and fixing part is used to support and fix the syringe, and the needle protection sleeve 2 is used...

Embodiment 2

[0042] Such as Figure 6~7 As shown, this embodiment provides a syringe needle protection device. The difference from Embodiment 1 is that the locking device includes a locking block 15, which is fixedly arranged on the outer wall of the needle protection sleeve 2, and slides on the side of the connecting sleeve 3. The wall is provided with a vertical groove 16 and an upper transverse groove 17 and a lower transverse groove 18 respectively connected to the upper and lower ends of the vertical groove 16. When the needle head protrudes from the needle inlet and outlet 4, the clamping block 15 is snapped into the upper transverse groove 17 , lock the needle protection sleeve 2 and the sliding connection sleeve 3; when the needle is located in the needle protection sleeve 2, the locking block 15 is snapped into the lower transverse groove 18, and the needle protection sleeve 2 and the sliding connection sleeve 3 are locked to prevent the needle protection sleeve from 2 and the sli...

Abstract

The invention discloses a needle protection device for a syringe, which relates to the technical field of medical equipment. A syringe fixing sleeve includes a sliding connecting sleeve and a supporting and fixing part, one end of the sliding connecting sleeve is fixedly connected with the supporting and fixing part, and the other end of the sliding connecting sleeve is sleeved on the needle One end of the protective cover, the other end of the needle protective cover is provided with a needle inlet and outlet, and an elastic support seat is fixed inside the needle protective cover. To support and fix the needle cylinder, push the needle cylinder fixing sleeve to make the needle cylinder squeeze the elastic support seat and make the needle protrude from the needle inlet and outlet. Locked, after unlocking the locking mechanism, the needle can be bounced back into the needle guard. The structure is simple, the needle of the syringe can be protected, pollution and accidental injury caused by exposure of the needle can be avoided, and the cost can be reduced by being able to be reused.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a syringe needle protection device. Background technique [0002] Once the needle protective cover of the syringe commonly used in the market is pulled out, the needle is exposed, and the needle is easy to contact with other objects, which may cause pollution to the needle, and the exposed needle is easy to cause accidental injury. Therefore, needle contamination and accidental injury caused by the exposure of syringe needles is a problem that we need to solve urgently. [0003] In the prior art, such as the patent CN200580042856.4, by adding a spring to the needle at the front end of the syringe, the needle is placed in the syringe sleeve before injection. During injection, the needle is stuck on the front end of the sleeve for injection. A spring springs the needle back into the sleeve so that the needle is not exposed before or after use. However, the above-menti...
