Abstract
The invention relates to medical equipment, in particular to a thread-off prevention syringe and a syringe needle. The thread-off prevention syringe comprises a syringe, washers, barrier strips, a connecting strip and a liquid outlet, and the syringe needle comprises check strips, a needle stand, a pinhead and fins. A pair of washers is arranged on both sides of the liquid outlet symmetrically by taking the axle center of the syringe as a center, each washer is a sector plastic sheet concentric with the liquid outlet, the inner side of each washer is provided with the barrier strip which has a semicircular cross section and is arranged along the diameter direction of the washer, a pair of fins is arranged on the periphery of the bottom of the needle stand by taking the axis center of the pinhead as a center, the fins are of sector shapes on a plane, and one check strip is arranged on the outer side of the periphery in the anti-clockwise direction of each fin. The invention completely eradicates the possibility of the separation of the syringe needle from the syringe in the process of use.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly relate to a kind of anticreep syringe and entry needle.
Background technology
Conventional injector is made up of needle tubing and syringe needle; The liquid outlet of needle tubing docks through taper surface with the needle stand of syringe needle, when the patient is carried out intramuscular injection, syringe needle sometimes can occur and dock not tight with needle tubing and phenomenon that syringe needle comes off; This moment is the waste medicinal liquid easily; Butt joint possibly produce bubble once more, reduces injection efficiency, increases patient's misery.
Summary of the invention
The present invention provides a kind of syringe needle of syringe and anticreep syringe and entry needle that needle tubing comes off avoided for solving the deficiency of prior art.
The scheme that solves technical problem of the present invention is: the anticreep syringe by syringe, nest plate, blend stop, connect bar and liquid outlet constitutes, entry needle is made up of non-return bar, needle stand, syringe needle and fin.
At the middle part of the front end face of syringe be with syringe be holistic columnar liquid outlet, be that a pair of axle center with syringe is the nest plate of centrosymmetric image in the both sides of liquid outlet.Each nest plate is the fan-shaped plastic sheet with the liquid outlet concentric, and the periphery of nest plate and clockwise straight flange connect bar and arcual to connect bar bonding with the end face of syringe through rectilinear respectively.Also have in the inboard of each sheet nest plate a sliver transvers section be semicircular, along the blend stop that the diametric(al) of nest plate is provided with, blend stop and nest plate are as a whole.Fore-and-aft distance between the front end outer wall of nest plate and syringe equals 5/6 of said blend stop cross section semicircle diameter.
Syringe needle is positioned at the shaft core position of columnar needle stand, and it is the fin of centrosymmetric image that the bottom margin of needle stand is provided with a pair of axle center with syringe needle, and fin is fan-shaped in the plane.The outside at the anticlockwise edge of each fin have shape of cross section size identical with blend stop, along the diametric non-return bar of fin.The central angle of fin is less than the inward flange and the rectilinear inboard angle that connects bar of blend stop.The overall diameter of fin is less than the arcual interior diameter that connects bar.
Adopt such scheme, can reach following effect:
During use, only need be enclosed within on the liquid outlet needle stand and the needle stand that turns clockwise earlier, when two fins were threaded into two nest plates and two non-return bars respectively and arrive the clockwise side of two blend stops respectively, anticreep syringe and entry needle promptly were fixed.At this moment, two blend stops are arranged to the stopping of two non-return bars, and two nest plates fixing to two fins are arranged at longitudinal direction at in-plane, so just stopped entry needle in use with the probability of syringe disengaging.Therefore the present invention has higher reliability, can improve injection efficiency, alleviates patient's misery.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further description.
The anticreep syringe by syringe 1, nest plate 2, blend stop 3, connect bar 4 and liquid outlet 5 constitutes, entry needle is made up of non-return bar 6, needle stand 7, syringe needle 8 and fin 9.At the middle part of the front end face of syringe 1 is to be holistic columnar liquid outlet 5 with syringe 1, is nest plates 2 that a pair of axle center with syringe 1 is a centrosymmetric image in the both sides of liquid outlet 5.Each nest plate 2 is the fan-shaped plastic sheets with liquid outlet 5 concentrics, and the periphery of nest plate 2 and clockwise straight flange connect bar 4 and arcual to connect bar 4 bonding with the end face of syringe 1 through rectilinear respectively.Also have in the inboard of each sheet nest plate 2 sliver transvers section be semicircular, along the blend stop 3 that the diametric(al) of nest plate 2 is provided with, blend stop 3 is as a whole with nest plate 2.Fore-and-aft distance between the front end outer wall of nest plate 2 and syringe 1 equals 5/6 of said blend stop cross section semicircle diameter.Syringe needle 8 is positioned at the shaft core position of columnar needle stand 7, and the fin 9 that it is centrosymmetric image that the bottom margin of needle stand 7 is provided with a pair of axle center with syringe needle 8, fin 9 are fan-shaped in the plane.The outside at the anticlockwise edge of each fin 9 have shape of cross section size and blend stop 3 identical, along fin 9 diametric non-return bars 6.The central angle of fin 9 is less than the inward flange and the rectilinear inboard angle that connects bar 4 of blend stop 3.The overall diameter of fin 9 is less than the arcual interior diameter that connects bar 4.
