Description

A kind of anti-acupuncture syringe

Technical field

This utility model belongs to technical field of medical instruments, is specifically related to a kind of anti-acupuncture syringe.

Background technology

Safe re-use preventing once-used syringe is widely used in medical field, has avoided using unhygienic syringe and the viral cross infection that produces.But common disposable syringe is because the problem of structure causes certain operations person still can carry out secondary use or repeatedly use, the violation operation of user produces cross infection, though safe re-use preventing once-used syringe can prevent the repeated use of syringe, entry needle exposes and makes discarded syringe produce many inconvenience in processes such as collection, transportation, processing but syringe uses the back, still might stab medical worker and other related personnel, cause the cross infection of virus and bacteria.

Therefore, designing a kind of the use for the new disposable that entry needle is protected and prevent the acupuncture syringe, is the urgent needs in current market.

The utility model content

Goal of the invention: at the deficiencies in the prior art, the purpose of this utility model provides a kind of anti-acupuncture syringe, and it can not be used by secondary, can cross infection, in last handling process, entry needle is granted asylum, be difficult for scratching the people, be conducive to the healthy of people; Simultaneously, this anti-acupuncture syringe construction is rationally simple, easy to manufacture, cheap, can satisfy user demand.

Technical scheme: in order to realize the foregoing invention purpose, the technical solution adopted in the utility model is as follows:

A kind of anti-acupuncture syringe comprises the syringe, entry needle and the safe needle guard that are used, and described syringe is screw socket syringe or the socket syringe of being furnished with the spiral needle stand; Described safe needle guard comprises interconnective sleeve and cylinder, is provided with the thin slice of chucking entry needle in the described sleeve, and described cylinder is provided with bayonet socket; Described bayonet socket and screw socket syringe chucking, after the cooperation, described cylinder is engaged between screw socket syringe and the entry needle; Described bayonet socket and spiral needle stand chucking, after the cooperation, described spiral needle stand is connected between entry needle and the socket syringe.

Preferably, described spiral needle stand comprises needle holder, is respectively equipped with coupling and nipple at the two ends of needle holder; Be provided with thread head in described needle holder, circle being provided with screw thread in thread head, and cylindrical is provided with the outer warp with the bayonet socket interlocking of described cylinder, after the cooperation, described cylinder and thread head by bayonet socket and outward warp closely be connected mutually.

Preferably, described sleeve and cylinder junction are provided with snak link.

Preferably, described bayonet socket be in the cylinder week convex structure on axially.

Preferably, there is being trip to cooperate with grab on the sleeve above the described cylinder.

Preferably, described thin slice is located on the intermediate inner wall of sleeve.

Preferably, described thread head and needle holder are integral structure.

Preferably, described nipple and coupling are the 6:100 joint.

Anti-acupuncture syringe of the present utility model can be anti-acupuncture screw socket syringe or anti-acupuncture socket syringe; When syringe was the screw socket syringe, the screw socket syringe was provided with screw socket, did not therefore need the spiral needle holder structure; By the bayonet socket of convex structure axially is set in week in cylinder, can be with more firm being sleeved on the injector syringe of this safe needle guard; By between cylinder and sleeve, snak link being set, make sleeve to rotate and to dock with cylinder around snak link, reach the purpose of closed injection pin; By in the middle of sleeve, thin slice being set, can block entry needle, can not scratch the people when avoiding intersecting use yet.

Operation principle: after injection finishes, by sleeve around the rotation of the snak link safe needle guard that closes, trip and grab interlocking; sleeve docks with cylinder; make the thin slice in the sleeve block entry needle, cause reaching the safeguard protection purpose in entry needle is enclosed in by safe needle guard.

Beneficial effect: the anti-acupuncture syringe that this utility model is used, rational in infrastructure simple, not only can be made into the screw socket syringe and can also be made into the socket syringe, make the injector syringe of each kind can join safe needle guard and become anti-acupuncture syringe, and can accomplish can not secondary to use, can cross infection; In last handling process, entry needle is granted asylum, be difficult for scratching the people, be conducive to the healthy of people, and product is easy to manufacture, cheap, use safety, can produce good economic benefits and social benefit, have good practicability.
