Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further explained below.

Referring to fig. 1 to 3, the self-destruct vaccine syringe with improved operational stability comprises a needle 100, a barrel 200 and a core rod 300.

The front end of the needle 100 is used for injection, the inside of the needle 100 is a fluid passage 100a, the rear end of the needle 100 is mounted at the front end of the cylinder 200, the inside 200a of the cylinder 200 is a cavity, and the core bar 300 is slidably disposed in the inside 200a of the cylinder 200. The front end of the stem 300 in this embodiment is provided with a piston 310 engaged with the inside 200a of the cylinder 200.

A stabilizing member 400 is provided at the rear end of the needle 100 to improve the operational stability, and the stabilizing member 400 in this embodiment is preferably a stabilizing pad, and the stabilizing pad 400 is provided in a circular configuration. The middle of the stabilization pad 400 is provided with a groove 400 a. The groove 400a can ensure that the stabilizing pad 400 does not contact the puncture point of the needle 100, avoiding infection. The stabilizing member 400 is fixed to the front end of the cylinder 200 by the coupling structure 500. The coupling structure 500 is preferably an adhesive, and the adhesive 500 is fixed to the inner wall of the front end of the cylinder 200 and coupled to one end of the stabilizing pad 400.

The back end of the syringe 200 is provided with a syringe self-destruction button 210, the back end of the core bar 300 is provided with a core bar self-destruction button 320 matched with the syringe self-destruction button 210, and when the front end of the core bar 300 is abutted against the front end of the syringe 200, the core bar self-destruction button 320 at the back end of the core bar 300 is clamped on the syringe self-destruction button 210 at the back end of the syringe 200. The rear end side of the cylinder 200 in this embodiment is provided with a cylinder crimping portion 220 for facilitating the operation of a nurse. When in injection, a nurse clamps the index finger and the middle finger on the curled edge part 220 of the syringe, and the thumb presses the core bar self-destruction button 320 to enable the front end of the core bar 300 to be abutted against the front end of the syringe 200, so that the core bar self-destruction button 320 is clamped on the syringe self-destruction button 210 to form self-locking, and the self-destruction function is achieved.
