Abstract
The utility model provides a disposable self destructing syringe, includes cylinder, push rod, piston and needle file, be equipped with a plurality of self -destruction felting needle bottom the cylinder inner chamber it has a plurality of self -destruction groove to open on the corresponding position of piston, one side of piston is seted up flutedly, has a tapered plug in the recess, the tapered plug is interference fit with the recess, is equipped with annular boss on the tapered plug I number, the inner chamber of needle file is provided with annular boss II numbers. The beneficial effects of the utility model are that self -destruction felting needle and self -destruction groove set up the service function that can destroy the piston to realize safe and reliable's self -destruction, in addition, I number annular boss on the tapered plug can also with II numbers mutual buckles of annular boss of needle file inner chamber, the export that can plug up the needle file equally also can realize the self -destruction. Duplicate protection can thoroughly stop the possibility that the syringe secondary used so that the self -destruction is more reliable.
Description
Technical field
This utility model relates to field of medical technology, is specifically related to a kind of disposable self-destruction syringe.
Background technology
Disposable sterilized syringe connects together with hypodermic needle, for liquid being injected into bodily tissue or therefrom extracted liquid.Some evil mind businessman is by the syringe recycling after use at present, therefore, causes a lot of malpracticees.In recent years, in order to prevent the secondary of syringe from using, successively also occurred various type self-destroyed style, but all due to complex structure, cost is high and be denied.Therefore, safe and reliable in the urgent need to one, and structure is simple, cheap self-destroyed syringe.
Utility model content
The purpose of this utility model is to provide a kind of disposable self-destruction syringe, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme:
A kind of disposable self-destruction syringe, comprise syringe, push rod, piston and needle stand, described syringe intracavity bottom is provided with several self-destruction prickers, and the opposite position of described piston has several self-destruction grooves; The side of described piston offers groove, has a conical plug in groove, and described conical plug and groove are interference fit, and conical plug is provided with No. I annular boss, and the inner chamber of described needle stand is provided with No. II annular boss.
The further effect of this utility model is: the handle end of described push rod is provided with locating part.
This utility model further effect is: described self-destruction pricker is provided with 4.
This utility model further effect is: described self-destruction pricker is evenly arranged in the bottom margin of syringe inner chamber.
The beneficial effects of the utility model be self-destruction pricker and self-destruction groove the using function that can destroy piston is set, to realize safe and reliable self-destruction; In addition, No. I annular boss on conical plug can also with the mutual buckle of needle stand inner chamber No. II annular boss, the outlet of needle stand can be blocked, equally also can realize self-destruction.Duplicate protection can make self-destruction more reliable, has thoroughly stopped the probability that syringe secondary uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of this utility model conical plug.
In figure: 1-needle stand, 2-No. II annular boss, 3-self-destruction pricker, 4-No. I annular boss, 5-conical plug, 6-piston, 7-push rod, 8-locating part, 9-syringe, 10-self-destruction groove.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making under creative work prerequisite
The every other embodiment obtained, all belongs to the scope of this utility model protection.
Refer to Fig. 1 and Fig. 2, in this utility model embodiment, a kind of disposable self-destruction syringe, comprise syringe 9, push rod 7, piston 6 and needle stand 1, described syringe 9 intracavity bottom is provided with several self-destruction prickers 3, and the opposite position of described piston 6 has several self-destruction grooves 10, and self-destruction pricker 3 can pierce through piston 6, the using function of broken meeting piston 6, thus realize self-destruction; The side of described piston 6 offers groove, a conical plug 5 is had in groove, described conical plug 5 is interference fit with groove, conical plug 5 is provided with No. I annular boss 4, the inner chamber of described needle stand 1 is provided with No. II annular boss 2, No. I annular boss 4 and No. II annular boss 2 buckle mutually, pull out the exit being trapped in needle stand 1, thus realize self-destruction from the groove of piston 6 by conical plug 5.
The handle end of described push rod 7 is provided with locating part 8, and locating part 8 can guarantee the inadvertent destruct of syringe when production and assembly and in use procedure.
Described self-destruction pricker 3 is provided with 4.Described self-destruction pricker 3 is evenly arranged in the bottom margin of syringe 9 inner chamber.
This utility model in use, removes locating part 8 after extracting medicinal liquid, and then promote push rod 7, then self-destruction pricker 3 penetrates self-destruction groove 10, and the function of broken meeting piston 6, realizes self-destruction; And No. I annular boss 4 on conical plug 5 and No. II annular boss 2 buckle mutually, conical plug 5 is pulled out from the groove of piston 6 exit being trapped in needle stand 1, thus also can realize self-destruction.
To those skilled in the art, obvious this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or basic feature, can realize this utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in this utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
