Problems solved by technology

Due to the excessive resistance during use, the pushing force is not easy to grasp, which will cause uneven force during the injection and cause pain and injury to the patient.
There is also a disposable self-destruct type direct injection ampoule. Before the syringe is used, there is space and air between the ampoule body piston of the handle and the bottom of the injection cylinder, which will easily cause the liquid medicine to leak from the ampoule body piston valve cutout. If the storage time is long, the piston will deteriorate and age, which will affect the use
There is also a disposable self-destruct type direct injection ampoule handle. The initial state of the ampoule body is located at the bottom of the injection cylinder, which causes the self-locking state to be unable to operate.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0019] like figure 1 The disposable self-destruct type direct injection ampoule shown, said disposable self-destruct type direct injection ampoule includes: injection cylinder 5, ampoule body 6, piston 8, the front end of ampoule body 6 is provided with piston 8, and the rear end is provided with handle 1 . In order to facilitate the liquid medicine to flow out, the piston 8 is provided with a notch 9, which forms a 40-50 degree oblique angle with the top surface of the piston 8 close to the inner wall of the syringe 5. The ampoule body 6 is provided with an annular groove 4 . As shown in FIG. 2 , a partially enlarged view of a disposable self-destructing direct injection ampoule A, a restricting shrapnel base 13 is fastened around the outer wall of one end of the groove 4 away from the handle...

Abstract

A self-destroyed directly injecting ampule is composed of an injection tube, an ampule body and a piston. It features its self-destroy structure consisting of a jamming slot structure at the tail of injection tube and the elastic piece arranged in the slot ring on ampule body.

Description

technical field [0001] The invention belongs to a medical injection appliance, in particular to a disposable self-destruction direct injection ampoule. Background technique [0002] At present, the existing disposable self-destructing direct injection ampoules on the market are locked by means of a mechanical slot provided outside the injection cylinder, which must be locked with artificial force when pushed in. Due to the excessive resistance during use, it is not easy to grasp the pushing force, which will cause uneven force during the injection and cause pain and injury to the patient. There is also a disposable self-destruct type direct injection ampoule. Before the syringe is used, there is space and air between the ampoule body piston of the handle and the bottom of the injection cylinder, which will easily cause the liquid medicine to leak from the ampoule body piston valve cutout. The piston will deteriorate and age after being stored for a long time, which will aff...
