Disposable germfree self-destruction type liquid medicine injector

Abstract

The invention discloses a disposable germfree self-destruction type liquid medicine injector. A liquid outlet head is arranged at the front end of a sleeve. A liquid outlet channel is arranged in the liquid outlet head. A piston body is arranged in the sleeve. A push-pull rod is connected with a piston head through a connecting rod. The diameter of the connecting rod is smaller than the diameter of the push-pull rod. A clamping rod extends from the front end of the piston head. A clamping head extends from the front end of the clamping rod. The diameter of the clamping head becomes larger gradually from front to back, smooth transition is achieved on the clamping head, and therefore a conical structure is formed. The diameter of the rear end of the clamping head is larger than the diameter of the clamping rod and the diameter of the liquid outlet channel. An axially penetrating groove penetrates through the clamping rod and the clamping head. Under the action of pushing force, the clamping head conducts radial shrinkage at the position of the axially penetrating groove so as to pass through the liquid outlet channel. After passing through the liquid outlet channel, the clamping head recovers in the radial direction and is clamped at the end of the liquid outlet head. Under the action of pulling force, the push-pull rod and the piston head are disconnected at the position where the push-pull rod and the piston head are connected through the connecting rod, and then self destruction is achieved. According to the disposable germfree self-destruction type liquid medicine injector, the structure is simple, injection is accurate, self destruction is thorough, and practical popularization and application is facilitated.

Description

technical field [0001] The invention relates to the technical field of self-destructing syringes, in particular to a disposable aseptic self-destructing drug-dissolving syringe. Background technique [0002] Syringes are medical devices that people often use in medical activities. In order to prevent cross-infection, disposable syringes have attracted more and more attention. At present, there are many forms of single-use syringes on the market. These syringes are discarded after use and cannot be reused. The phenomenon is very common, and the re-entry of used syringes into the medical market will cause cross-infection of injectors, seriously threatening people's lives and health. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a disposable aseptic self-destruct drug-dissolving syringe, which has a simple structure, accurate injection, complete self-destruction, and is convenient for ...
