Abstract
The utility model discloses a self-ruined syringe, comprising a syringe body (1), a pushing rod (2) and a needle (3). The utility model is characterized in that the back of the syringe body (1) is provided with a flange (4) and the front is provided with a needle stand (6). A positioning subassembly (7) is equipped in the needle stand (6). The needle (3) and the needle stand (6) are fixedly connected. The back of the pushing rod (3) is provided with a flange (8) and the front is provided with a pushing rod fixing seat (9) which is orderly equipped with a first pyramid (10), a second pyramid (11), a fixing ring seat (12) and a clamping body (13) from the back to the front with the first pyramid (10) pressing the second pyramid (11) to form a point contact. The first pyramid (10), the second pyramid (11) and the fixing ring seat (12) are equipped inside a ring plug (14), with the first pyramid (10) clamping connected with the ring plug (14), the fixing ring seat (12) fixed to the ring plug (14) and the clamping body (13) exposed at the front of the ring plug (14). The self-ruined syringe can avoid the problem that illegal people reuse disposable syringes after recycling them.
Description
Technical field
It is a kind of syringe that this utility model relates to, particularly a kind of self-destruction syringe.The technical field that belongs to disposable syringe.
Background technology
The traditional type syringe can carry out disinfection, and then reuse after finishing using.If it is improper to occur, during use, will there be the infected danger of patient on the disinfectant link.Therefore, having occurred after a kind of use once at present is discardable disposable syringe, but this kind syringe after use, therefore the structure of whole injector syringe still can be kept perfectly, and exists the lawless person to reclaim the danger of still using behind the syringe.
The utility model content
This utility model technical issues that need to address, i.e. the purpose of this utility model is for a kind of self-destruction syringe is provided, this self-destruction syringe can solve the problem that existing disposable syringe is used by secondary.
Technical problem of the present utility model can solve by taking following measure:
A kind of self-destruction syringe comprises syringe, push rod, syringe needle, and its construction features is: back end of syringe is provided with flange, front end is provided with needle stand, is provided with a limiting component in the described needle stand, and syringe needle is fixedlyed connected with needle stand; Putting back-end can be provided with a flange, front end can be provided with a push rod holder, the push rod holder can be provided with first cone, second cone, fixing ring seat and fix body back to front in regular turn, first cone is pressing second cone to form the some contact, first cone, second cone, fixedly ring seat places in the ring taps, first cone is connected in the ring taps, fixedly ring seat and ring taps are fixed, and fix the external ring taps front end that is exposed to.
When push rod was pushed forward to the end, the limiting component in the needle stand can be clamped in the needle stand fixing body, push rod pull back in the time, first cone, second cone are separated, first cone breaks away from ring taps.
This utility model technical solution problem, can also take following measure:
Aforesaid fixing body can be provided with a guide portion, and described guide portion inwardly forms the buckle limit towards fixedly ring seat one side and outwards expansion in the guide portion bottom side.
Aforesaid syringe stack shell place can be provided with scale.
Can be provided with a hole on the aforesaid fixing body.
Aforesaid needle stand is outer can be provided with a cap, and cap can be placed in syringe needle in it.
The utlity model has following outstanding effect:
When 1, using this utility model, after the injection injection finishes in the syringe, push rod is pushed forward to the end again, the fixing body of push rod front end will be pushed in the needle stand, thereby the limiting component that fixes in body and the needle stand blocks mutually; Then, again with push rod toward pulling back, first cone will break away from ring taps, and separate with second cone, at this moment, fix body and be clamped in the needle stand, second cone in ring taps and the ring taps, fixedly ring seat all can be kept somewhere in syringe, and the push rod and first cone will be pulled out outside the syringe, and whole syringe can't be reused.Therefore this utility model can avoid unauthorized person to reclaim the drawback that reuses behind the disposable syringe.
2, this utility model is provided with a cap, and cap can be placed in syringe needle in it.Cap is placed in syringe needle and makes people in it when used syringe is reclaimed in cleaning, can avoid the personnel's of clearing up hands to be stabbed wound by syringe needle, has guaranteed the personnel's that reclaim safety.This utility model is simple in structure, and is safe, is the ideal substitute of prior art shot device.

The specific embodiment
Below in conjunction with specific embodiment this utility model is specifically described.
Specific embodiment 1:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.Present embodiment is made up of syringe 1, push rod 2 and syringe needle 3.The rear end of syringe 1 is provided with flange 4, and front end is provided with the needle stand 6 of a hollow.Be provided with a limiting component 7 in the needle stand 6, limiting component 7 is an annular projection.Syringe needle 3 is fixed in the needle stand 6.
Operation principle: when push rod 3 was pushed forward to the end, the guide portion 15 that fixes on the body 13 can be so that fix body 13 and enter in the needle stand 6.Limiting component 7 in the needle stand 6 can will fix body 13 and be clamped in the needle stand 6 at 16 places, buckle limit.Push rod 3 pull back in the time because ring taps 14 has elastic reaction, first cone 10, second cone 11 are separated, first cone 10 breaks away from ring taps 14.At this moment, because ring taps 14 is with fixedly ring seat 12 is fixing, so second cone 11, fixedly ring seat 12, ring taps 14 can and together be stuck in the syringe 1 with fixing body 13.
Specific embodiment 2:
The characteristics of this specific embodiment are: described syringe 1 stack shell place is provided with scale.Be provided with a cap 20 outside the needle stand 6, cap 20 can be placed in syringe needle 3 in it.All the other are with specific embodiment 1.
