Abstract

The utility model discloses a self-destructive safety syringe which comprises a needle tube, a push rod, a piston, a connector and a needle seat; a jockey for position is arranged between the connector and the needle tube; the inner hole of the connector is provided with an elastic slot; the top end of the push rod is provided with a hook which can be inserted into the elastic slot; an auxiliary rotation device capable of driving the connector to rotate bacause the push rod is arranged between the connector and the push rod; the self-destructive safety syringe can be self-destructive after being used, so as to prevent lawless persons from recovering the disposable syringe, and the disposable syringe can be prevented from being re-treated and flowing into the market to be reused after being used; in addition, the destructed needle seat is retracted into the needle tube, which prevents the exposed needle tip in the follow-up treatment form stabbing the medical staff or the cleaners, and new cross infection.

Description

Self-destroy safety injector

Technical field

This utility model relates to a kind of syringe, the safety injector that can damage voluntarily after particularly a kind of injection finishes.

Background technology

For preventing cross infection, the syringe that adopts is disposable use at present.Disposable syringe is after finishing using, because syringe needle is exposed outside, exposed syringe needle very easily stings and scratches medical worker or Cleaner in processing procedure subsequently, causes new cross infection.Moreover some lawless persons are subjected to ordering about of interests might reclaim not the disposable syringe of damaging, thus disposable syringe still exist use after handle again come into the market reusable may.

Summary of the invention

In order to overcome the deficiencies in the prior art, this utility model provides a kind of safety injector that can damage voluntarily.

The technical scheme that its technical problem that solves this utility model adopts is:

Self-destroy safety injector, comprise syringe, push rod, piston, joint and needle stand, it is characterized in that being provided with positioner between described joint and the syringe, the joint endoporus is provided with the elasticity draw-in groove, the top of push rod is provided with the trip that can insert in the elasticity draw-in groove, is provided with the auxiliary rotary apparatus that joint is rotated with push rod between joint and the push rod.

As this utility model preferred embodiment, above-mentioned positioner is the screens that is arranged on the fixture block of joint lateral wall and is arranged on the syringe medial wall.

Above-mentioned fixture block is provided with two, and it is oppositely arranged on the joint lateral wall, and described screens is correspondingly provided with two, and it is oppositely arranged on the medial wall of syringe.

Auxiliary rotary apparatus of the present utility model is the reinforcement that is separately positioned on joint and push rod cooperation place.

As the improvement of the above-mentioned embodiment of this utility model, pointed shape is arranged in the end of described reinforcement.

As the further improvement of the above-mentioned embodiment of this utility model, described push rod is provided with the recess that fractures.

On the above-mentioned needle stand protecting cover is installed.

The beneficial effects of the utility model are: this utility model is provided with positioner between joint and syringe, the joint endoporus is provided with the elasticity draw-in groove, the top of push rod is provided with the trip that can insert in the elasticity draw-in groove, be provided with the auxiliary rotary apparatus that joint is rotated with push rod between joint and the push rod, this utility model is after finishing using like this, the light push rod of pressing, trip is inserted in the elasticity draw-in groove, rotate push rod simultaneously, joint rotates with push rod under the effect of auxiliary rotary apparatus, positioner between joint and the syringe is thrown off, retract push rod again, joint and needle stand are under the pulling of push rod in the retraction syringe, push rod then fractures, putting into collection box gets final product, this utility model can be damaged after use voluntarily, therefore what can prevent that the lawless person is subjected to interests orders about the recovery disposable syringe, stop the disposable syringe use after handle the reusable possibility that comes into the market again, and, needle stand after the damage bounces back in the syringe, scratch medical worker or Cleaner to prevent that syringe needle exposed in processing procedure subsequently from stinging, and then prevent the generation of new cross infection.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the disclosed self-destroy safety injector of this utility model, comprise syringe 1, push rod 2, piston 3, joint 4 and needle stand 5, protecting cover 6 is installed on the needle stand 5, between joint 4 and syringe 1, be provided with positioner, joint 4 endoporus are provided with elasticity draw-in groove 7 (as shown in Figure 7), the top of push rod 2 is provided with trip 8, syringe can make trip 8 insert in the elasticity draw-in groove 7 by light pressure push rod 2 after injection, is provided with the auxiliary rotary apparatus that joint is rotated with push rod between joint 4 and push rod 2.

With reference to Fig. 5, Fig. 6, Fig. 7, positioner is the screens 10 that is arranged on the fixture block 9 of joint 4 lateral walls and is arranged on syringe 1 medial wall; And fixture block 9 can be provided with two, and it is oppositely arranged on the lateral wall of joint 4, and screens 10 simultaneously also relative set is two, and it is oppositely arranged on the medial wall of syringe 1, and syringe fixture block and screens in use cooperatively interacts, and gets loose from syringe to prevent joint.

With reference to figure Fig. 6, Fig. 7, Fig. 8, the auxiliary rotary apparatus that this utility model adopts is the reinforcement 11 that is separately positioned on joint 4 and push rod 2 cooperation places, and pointed shape is arranged in the end of reinforcement 11, produce holding capacity when stepping down automatically to avoid injecting, reinforcement by joint and push rod cooperation place can drive the joint rotation after can making injector to inject when the rotation push rod simultaneously, so that the positioner between joint and the syringe gets loose.

Push rod 2 is provided with the recess 12 that fractures, and syringe can fracture push rod along the recess that fractures after injection finishes, to make things convenient for the damage of syringe.

When using this self-destroy safety injector, light pressure protecting cover is so that take out protecting cover, extract medicinal liquid again, after injection finishes, the light push rod of pressing, trip is inserted in the elasticity draw-in groove, simultaneously push rod is revolved and turn 90 degrees, joint revolves with push rod under the effect of reinforcement and turn 90 degrees, fixture block and screens between joint and the syringe are thrown off, the push rod of pulling back again, joint and needle stand in the retraction syringe, fracture push rod along the recess that fractures under the pulling of push rod then, putting into collection box gets final product, therefore this utility model can be damaged after finishing using voluntarily like this, and what can prevent that the lawless person is subjected to interests orders about the recovery disposable syringe, stop that disposable syringe uses after handle again come into the market reusable may, and, needle stand after the damage bounces back in the syringe, scratches medical worker or Cleaner to prevent syringe needle thorn exposed in processing procedure subsequently, and then prevents the generation of new cross infection.
