Description
Technical field
This utility model is a kind of syringe of anti-pricking wound, belongs to technical field of medical instruments.
Background technology
In prior art, have pin cap at the pinhead sleeve of syringe, for keep syringe needle clean, prevent syringe needle from stabbing people.Pin cap inwall has multiple projection, and syringe needle is provided with convex edge, when pin cap is enclosed within syringe needle slidably, described projection contacts with convex edge, and pin cap inwall is expanded, in the protruding draw-in groove moved to further on syringe needle, thus by pin cap sleeve on syringe needle, and pin cap can be limited again come off from syringe needle.But the force limited that this restriction pin cap comes off, pin cap still comes off from syringe needle with comparalive ease.
Utility model content
For the deficiency that prior art exists, this utility model object is to provide a kind of syringe of anti-pricking wound, the problem proposed in above-mentioned background technology is solved by adding Fastener, this utility model structure is simple, easy to use, can effectively prevent pin cap from coming off from syringe needle, the thing stopping scathing occurs.
To achieve these goals, this utility model realizes by the following technical solutions: a kind of syringe of anti-pricking wound, comprise empty cylinder, the nipple be communicated with described empty cylinder, be set in described Supramammillary syringe needle and be set in the pin cap on described syringe needle, described pin cap sleeve one end on syringe needle has convex edge, also comprise the Fastener for applying clamping force to pin cap be set near empty cylinder one end on nipple, described Fastener comprises the multiple claws being set in Supramammillary fixed cover and evenly arranging along described fixed cover circumference, the end of described claw has inside projection, pin cap is enclosed within the process on syringe needle movably, and described convex edge and described projection contacts also outwards strut claw, pin cap sleeve on syringe needle after, described projection can block convex edge.
Further, also comprise the bail wire that can be slidably matched with multiple described claw, described bail wire outwards struts for limiting claw.
Further, the end of described claw is provided with outside rib.
Further, described projection is semi-cylindrical.
Further, described claw is provided with 3.
The beneficial effects of the utility model: the syringe of a kind of anti-pricking wound of the present utility model, comprise empty cylinder, the nipple be communicated with described empty cylinder, the pin cap that is set in described Supramammillary syringe needle and is set on described syringe needle, described pin cap sleeve one end on syringe needle has convex edge, also comprise the Fastener for applying clamping force to pin cap be set near empty cylinder one end on nipple, described Fastener comprises the multiple claws being set in Supramammillary fixed cover and evenly arranging along described fixed cover circumference, and the end of described claw has inside projection; Pin cap is enclosed within the process on syringe needle movably, and described convex edge and described projection contacts also outwards strut claw; Pin cap sleeve on syringe needle after, described projection can block convex edge.By Fastener and bail wire, can effectively prevent pin cap from coming off from syringe needle, the thing stopping scathing occurs.Meanwhile, the syringe construction of anti-pricking wound of the present utility model is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the perspective view of Fastener of the present utility model;
Fig. 3 is the perspective view that the bail wire of this practicality is enclosed within Fastener.
Detailed description of the invention
The technological means realized for making this utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth this utility model further.
Refer to Fig. 1 to Fig. 3, this utility model provides a kind of technical scheme: a kind of syringe of anti-pricking wound, comprise empty cylinder, the nipple 1 be communicated with described empty cylinder, the pin cap 3 being set in the syringe needle 2 on described nipple 1 and being set on described syringe needle 2, described pin cap 3 one end be enclosed within syringe needle 2 has convex edge 31, also comprise the Fastener 4 for applying clamping force to pin cap 3 be set near empty cylinder one end on nipple 1, described Fastener 4 comprises the fixed cover 41 be set on nipple 1 and the multiple claws 42 evenly arranged along described fixed cover 41 circumference, the end of described claw 42 has inside projection 421, pin cap 3 is enclosed within the process on syringe needle 2 movably, and described convex edge 31 contacts with described protruding 421 and outwards struts claw 42, pin cap 3 is enclosed within after on syringe needle 2, and described protruding 421 can block convex edge 31.During use, first Fastener 4 is enclosed within nipple 1, again syringe needle 2 is enclosed within nipple 1, finally pin cap 3 is enclosed within syringe needle 2, multiple described protruding 421 and then block convex edge 31, thus be applied with a clamping force at the outer wall of pin cap 3, cooperate with the clamping force of the inwall of pin cap 3, can effectively clamp pin cap 3, prevent pin cap 3 from coming off from syringe needle 2, the thing stopping scathing occurs.
As the further improvement of such scheme, also comprise the bail wire 5 that can be slidably matched with multiple described claw 42, described bail wire 5 outwards struts for limiting claw 42.Described bail wire 5 is enclosed within the outer wall of multiple claw 42, when claw 42 blocks convex edge 31, stirs bail wire 5, is located at one end claw 42 with projection 421, so just can plays good clamping effect.
As the further improvement of such scheme, the end of described claw 42 is provided with outside rib 422, object prevents bail wire 5 from slippage claw 42.
As the further improvement of such scheme, described protruding 421, in semi-cylindrical, can facilitate pin cap 3 to be enclosed within syringe needle 2 or by pin cap 3 and pull up from syringe needle 2.
As the further improvement of such scheme, described claw 42 is provided with 3, arranges like this and can ensure to clamp effect, can save material again.
More than show and describe ultimate principle of the present utility model and principal character and advantage of the present utility model, 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, this utility model can be realized 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.
