Abstract
The invention relates to a protective injection syringe with an outer sleeve. After a common injection syringe is used, a syringe needle is sleeved by a sleeve, then the injection syringe is discarded, while since the sleeve and the injection syringe body are independent parts, a user often has the finger stick injuries due to the improper sleeving operation, and consequently, infection accidents are easily caused. The protective injection syringe provided by the invention comprises a syringe needle, a syringe tube and a push rod, wherein the push rod is sleeved by the transparent cylinder-shaped outer sleeve, a limiting groove is arranged on the inner wall of the outer sleeve, and is composed of radial short horizontal groove bodies on the upper and lower ends and an axial long vertical groove body communicating one ends of the short horizontal groove bodies; one end, close to the syringe needle, of the outer wall of the syringe tube is provided with a limiting bulge clamped and embedded into the limiting groove. The protective injection syringe is simple in structure and low in cost, and the syringe needle of the injection syringe after being used can be effectively protected, so that the stick injuries and infection caused by the improper operation are avoided.
Description
Technical field
The invention belongs to medical auxiliary apparatus technical field, be specifically related to a kind of protection type trocar sheath syringe.
Background technology
Syringe use after need chuck sleeve pipe on syringe needle to abandon, be then uniformly processed as medical waste, if syringe needle is not carried out necessity protection, can cause transhipment or processing procedure in stab situation.And sleeve pipe and syringe body are individual components separated from one another, user often stabs finger because of chuck misoperation, easily causes infection accident.
Summary of the invention
It is an object of the invention to provide a kind of protection type trocar sheath syringe, install slidably sleeve pipe on the injector additional, after convenient use, syringe needle is protected.
The technical solution adopted in the present invention is:
Protection type trocar sheath syringe, including syringe needle, injection tube and push rod, it is characterised in that:
Being cased with transparent cylindrical jacket pipe outside push rod, outer sleeve inner wall is provided with stopper slot, and stopper slot is made up of the long vertical slot that the hyphen groove of upper and lower two ends radial direction is axial with connecting hyphen groove one end；
Injection tube outer wall is provided with, near one end of syringe needle, the spacing preiection that card is embedded in stopper slot.
The length of trocar sheath is less than the length of injection tube, more than the length of syringe needle.
The invention have the advantages that
Present configuration is simple, with low cost, can the syringe needle of syringe after using effectively be protected, it is to avoid stab because of what misoperation occurred and infect.
Accompanying drawing explanation
Fig. 1 is sectional side elevation of the present invention.
Fig. 2 is trocar sheath sectional side elevation.
In figure, 1-syringe needle, 2-injection tube, 3-push rod, 4-trocar sheath, 5-stopper slot.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention will be described in detail.
A kind of protection type trocar sheath syringe that the present invention relates to, including syringe needle 1, injection tube 2 and push rod 3, being cased with transparent cylindrical jacket pipe 4 outside push rod 3, trocar sheath 4 inwall is provided with stopper slot 5, and stopper slot 5 is made up of the long vertical slot that the hyphen groove of upper and lower two ends radial direction is axial with connecting hyphen groove one end.Injection tube 2 outer wall is provided with, near one end of syringe needle 1, the spacing preiection that card is embedded in stopper slot 5.The length of trocar sheath 4 is less than the length of injection tube 2, more than the length of syringe needle 1.
During injection, the spacing preiection of injection tube 2 outer wall is positioned at trocar sheath 4 inwall hyphen groove near syringe needle, after having injected, and rotary sleeve pipe 4, the spacing preiection of injection tube 2 moves to long vertical slot, promote trocar sheath 4, make spacing preiection move to another hyphen groove place, road, again rotary sleeve pipe 4, spacing preiection moves to another road hyphen groove, trocar sheath 4 stretches out from injection tube 2, covers syringe needle 1, then abandons syringe.
Present disclosure is not limited to cited by embodiment, and the conversion of any equivalence that technical solution of the present invention is taked by those of ordinary skill in the art by reading description of the present invention, the claim being the present invention is contained.
