CN201871066U - Novel injector - Google Patents

Abstract

The utility model discloses a novel injector, which comprises a needle head, a needle tube and a pushing tube, wherein the needle head is connected with the front end of the needle tube in an insertion way, the pushing tube is arranged inside the needle tube, a filter is arranged in the insertion connection part of the needle head and the needle tube, a filter screen is arranged inside the filter, the front end of the pushing tube is provided with a rubber plug, and the shape of the rubber plug and the shape of the front end of the needle tube are mutually anastomotic. The novel injector disclosed by the utility model is characterized in that the filter is clamped and arranged at the insertion connection part of the needle head and the needle tube, so residue in sucked medicine liquid is absorbed by the filter screen, the phenomenon of injection blockage can not occur, the medicine liquid can be totally injected into the body of a patient without residue during the medicine liquid injection through installing the rubber plug with the shape anastomotic with the shape of the front end of the needle tube at the front end of the pushing tube, the waste of the medicine liquid is avoided, the structure is simple, and the operation is convenient.

Description

A kind of novel injector

Technical field

This utility model relates to medical instruments field, specifically a kind of syringe.

Background technology

The present syringe that uses, form by syringe needle, needle tubing and propelling movement pipe, syringe needle and needle tubing are pegged graft, the propelling movement pipe is sheathed in the needle tubing by the rear end of needle tubing, advance the air emptying in the needle tubing by pushing pipe, by syringe needle is inserted the medicinal liquid that needs injection, pull out to push to manage and draw medicinal liquid, promote to push pipe when giving patient injection medicinal liquid is injected in the patient's blood vessel.In traditional syringe use, there are a lot of drawbacks, such as in the process that extracts medicinal liquid, being easy to be equipped with the rubber stopper of medicine bottle of medicinal liquid or the rubber slag or the glass slag of glass bottle opening also sucks in the needle tubing, some very tiny residues just might inject in the patient body in injection so, give patient's the healthy potential safety hazard that causes; Say for another example, in the process that sucks medicinal liquid and liquid medicine injection, because the features of shape of needle tubing and propelling movement pipe, be easy to residual air between needle tubing and propelling movement pipe, so just make that the suction medicinal liquid is not thorough, all medicinal liquids all can not be injected in the patient body during liquid medicine injection, cause the residual of medicinal liquid.

Summary of the invention

For solving the technical problem of above-mentioned existence, this utility model provides a kind of syringe, when avoiding injecting residue is injected in patient's body, and medicinal liquid injects the phenomenon appearance that does not thoroughly remain in the needle tubing when avoiding injecting simultaneously.

For achieving the above object, the technical solution adopted in the utility model is as follows:

This syringe includes syringe needle, needle tubing and propelling movement pipe, syringe needle is plugged in the front end of needle tubing, push pipe and be located at needle tubing inside, syringe needle and needle tubing splicing position are provided with filter, filter interior is provided with drainage screen, the front end that pushes pipe is provided with rubber closure, and the shape of the shape of rubber closure and needle tubing front end is coincide mutually.

This utility model clamps defecator at the splicing position of syringe needle and needle tubing, make sucking residue in the medicinal liquid stays and is filtered net absorption and the injected plug phenomenon can not occur, by pushing the rubber stopper that the pipe front end is installed and needle tubing front end shape matches, make to push pipe in exhaust process with the thorough emptying of air, medicinal liquid can all inject in the patient body and not have and remain in the needle tubing during liquid medicine injection, avoided the waste of medicinal liquid, simple in structure, easy to operate.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment:

Below in conjunction with the drawings and specific embodiments this utility model is described in detail:

As shown in the figure, include syringe needle 1, needle tubing 2 and push pipe 3, syringe needle 1 is plugged in the front end of needle tubing 2, push pipe 3 rear ends and be sheathed on needle tubing 2 inside by needle tubing 2, syringe needle 1 is provided with filter 4 with needle tubing 2 splicing positions, filter 4 inside are provided with drainage screen 5, and the front end of described propelling movement pipe 3 is provided with rubber closure 6, and the shape of the shape of described rubber closure 6 and needle tubing 2 front ends is coincide mutually.In the present embodiment, the front end of needle tubing 2 is taper and cylindrical combination, and then rubber closure 6 also is taper and columniform assembly, and described rubber closure 6 is just in time fitted seamless with the front inner wall of needle tubing 2.

During use, at first promote to push the front end emptying air that pipe 3 arrives needle tubing 2, in the medicinal liquid bottle of needs injection, draw medicinal liquid by syringe needle 1, promoting to push pipe 3 medicinal liquids during injection injects in the patient body, because the effect of drainage screen 4, the rubber stopper slag or the glass slag of the medicinal liquid bottle of bringing in drawing the medicinal liquid process are attracted on the drainage screen 5, and the injected plug phenomenon can not occur; Because rubber stopper 6 is fitted fully with needle tubing 2 inwalls, can be when promoting to push pipe 3 emptying gas with the thorough emptying of air, more thorough when drawing medicinal liquid like this, do not have medicinal liquid during liquid medicine injection yet and remain in the needle tubing, cause the waste of medicinal liquid.

Claims (1)

1. novel injector, include syringe needle (1), needle tubing (2) and push pipe (3), syringe needle (1) is plugged in the front end of needle tubing (2), push pipe (3) and be located at needle tubing (2) inside, it is characterized in that: syringe needle (1) is provided with filter (4) with needle tubing (2) splicing position, filter (4) inside is provided with drainage screen (5), and the front end that pushes pipe (3) is provided with rubber closure (6), and the shape of the shape of rubber closure (6) and needle tubing (2) front end is coincide mutually.
