Abstract
The invention relates to a spiral mobile protective jacket type injector. An injector, after being used, is discarded by clamping and covering a casing on a needle head, and since the casing and an injector main body are mutually separated and independent parts, fingers of a user are always pricked because of improper clamping and covering and infection accidents are easily caused. The injector comprises a needle head, an injection tube and a push rod; a transparent cylindrical outer casing covers outside the push rod; inner screw threads, namely an upper inner screw thread and a lower inner screw thread, are arranged at both upper and lower ends of the inner wall of the outer casing; and the end, close to the needle head, of the outer wall of the injection tube is provided with an outer screw thread. The injector disclosed by the invention is simple in structure and low in cost; and the needle head of the used injector can be effectively protected, so as to avoid needle-sticking injury and infection due to improper operations.
Description
Technical field
The invention belongs to medical auxiliary apparatus technical field, be specifically related to a kind of spiral and move protection shell type 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 spiral and move protection shell type 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:
Spiral moves protection shell type syringe, including syringe needle, injection tube and push rod, it is characterised in that:
Being cased with transparent cylindrical jacket pipe outside push rod, the upper and lower two ends of outer sleeve inner wall are provided with female thread, for upper female thread and lower female thread；
Injection tube outer wall is provided with external screw thread near one end of syringe needle.
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, the upper female thread of 5-, female thread under 6-.
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 spiral that the present invention relates to moves protection shell type syringe, including syringe needle 1, injection tube 2 and push rod 3, is cased with transparent cylindrical jacket pipe 4 outside push rod 3, and the upper and lower two ends of trocar sheath 4 inwall are provided with female thread, for upper female thread 5 and lower female thread 6.Injection tube 2 outer wall is provided with external screw thread near one end of syringe needle 1.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 external screw thread of injection tube 2 outer wall and the upper female thread 5 of trocar sheath 4 screw, after having injected, rotary sleeve pipe 4, the external screw thread of injection tube 2 outer wall and the upper female thread 5 of trocar sheath 4 are outwarded winding, promote trocar sheath 4, the lower female thread 6 of trocar sheath 4 is moved to the external screw thread of injection tube 2 outer wall, again rotary sleeve pipe 4, the external screw thread of the lower female thread 6 of trocar sheath 4 and injection tube 2 outer wall is screwed, trocar sheath 4 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.
