Description
Technical field
This utility model relates to a kind of medical apparatus, and more particularly, it relates to a kind of self-destroyed syringe.
Background technology
Syringe is one of medical apparatus the most common in hospital, but mostly traditional disposable syringe can not damage after using voluntarily, some lawless persons are for trying to gain sudden huge profits, the disposable syringe of collection is reused, the health of the serious harm people, in order to solve the problem, many self-destruction syringes are disclosed a kind of Simple safe auto-disable syringe by the Chinese patent of example if application number is 201310299553.7, its syringe place is provided with self-desttruction equipment, although the self-destruction of syringe is achieved this, the syringe needle but it does not fracture, the most key point of self-destroyed syringe namely destroys syringe needle, syringe needle is briefly just extracted by the function that its structure realizes, thus make the syringe needle after extracting may be collected again to be inserted in conventional syringe by lawless person and use, again such as application number be 200410060106.7 Chinese patent openly the full self-destroyed syringe of safety and safety ruin pin needle collector, although special Aided design syringe collection box for needle or pin solves the recovery of syringe needle but to there is syringe needle itself be equally intact and self-destruction condition is restricted must could reclaim syringe needle under Aided design syringe collection box for needle or pin existence condition specially, if there is no this collection box for needle or pin out of doors at the complete rear syringe of emergency injection device even self-destruction all cannot realize saying nothing of reclaiming collect syringe needle, destroying not only piston in such as other patents makes syringe realize push-and-pull but the piston rod that I changes a same model installs not just but also can with not reaching complete self-destruction.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of safe self-breaking syringe, syringe needle can be fractureed to destroy and the syringe needle after fractureing can be made to be placed in recycling cavity not easily to drop, syringe can be made again completely to reuse.
For achieving the above object, this utility model provides following technical scheme:
A kind of safe self-breaking syringe, comprise needle stand, needle guard and syringe, described needle guard is provided with self-desttruction equipment, the inside of described needle guard is provided with collection pin chamber and pin openings, described collection pin chamber is communicated with by pin holes with pin openings, described needle guard is provided with through hole, described through hole is communicated with pin holes and arranges and be between collection pin chamber and pin openings, described self-desttruction equipment is located in through hole, described needle stand is provided with syringe needle, described syringe needle inserts pin holes and extends into collection pin intracavity, the inwall circumferencial direction of described needle stand is provided with the draw-in groove be evenly arranged, described syringe is provided with syringe nipple, the outer wall circumferencial direction of described syringe nipple is provided with the spacing fixture block be evenly arranged, described needle stand and the clamping of syringe nipple.
Pass through technique scheme, syringe needle can damage by self-desttruction equipment, and make pin base fastener be connected on locked on syringe nipple cannot taking off, thus cause whole syringe to reach scrapping can not use completely, syringe needle after fractureing can be stored in collection pin intracavity and avoid syringe needle to sting human infection pathogenic bacteria, and requisite for syringe needle guard being arranged to needle guard, to make self-destroyed syringe to be facilitated to place again syringe needle practicality after use syringe is complete high, and self-destruction is simple to operate.
As preferably, described self-desttruction equipment comprises the bent needle cutter and spring arranged in opposite directions, and described bent needle cutter is connected with pushing block, and described spring connects pushing block and needle guard.
By technique scheme, similar press-button structure is arranged to by self-desttruction equipment, by spring, the cutter that arranges in opposite directions is separated, and certain thrust must be needed to avoid maloperation encountered cutter untapped syringe is scrapped during self-destruction syringe needle.
As preferably, described pin openings is provided with slideway, and described needle stand outer wall is provided with draw runner, and described pin base fastener is connected to pin openings.
By technique scheme, transition clamping makes needle stand can not fall down when vertical, makes needle stand to be effectively placed in needle guard.
Compared with prior art, the utility model has the advantage of: needle guard is as the indispensable part of syringe, be designed to place the device that syringe needle can destroy again syringe needle, handled easily, self-destruction mainly destroys syringe needle and fundamentally destroys and avoid reusing of syringe needle, syringe needle after destruction can be stored in again collection pin intracavity and avoid syringe needle and drop out thorn avoids antibacterial infection to human body, the self-locking mechanism of needle stand is just stuck when inserting needle stand again cannot be changed in theory thus syringe cannot be reused, self-destruction effect is high, other self-destroyed syringe manufacturing costs are lower relatively, safe and reliable.
