Abstract

The utility model discloses a disposable injection needle comprising a needle seat, a hollow needle tube with the back end connected on the needle seat, and a protection sleeve with the front end closed and capable of being detachably sleeved on the needle tube. A con-shaped needle tip is arranged at the front end of the needle tube, and the needle seat and the needle tube are of an integrated structure and made from composite material in a one time injection molding mode. The needle seat and the needle tube integrally formed with composite material are adopted for the disposable injection needle, the danger that the needle tube is broken off in a human body can be reduced, the needle tip is burned to enable a needle hole to be closed and the needle tip to be inactivated or lost after medical workers finish injection, the possibility that residual medicine liquid in the needle tube flows out, namely disease is spread through the injection needle is fundamentally eliminated, the risk of accidental stab wound also can be reduced to a maximum extent, and the recycling utilization process of products is greatly simplified.

Description

A kind of Dispoable medical entry needle

Technical field

This utility model relates to a kind of medical apparatus, is specifically related to a kind of Dispoable medical entry needle.

Background technology

At present, the needle tubing of Dispoable medical entry needle normally adopts rustless steel to make.The Dispoable medical entry needle in clinical a large amount of uses so that clinical waste day by day increase, to hospital refuse and garbage rationally, the harmless treatment task is on the rise and urgent.For taking precautions against disposable aspiration needle by Reusability, control iatrogenic pollution and propagation, avoid causing social effects of pollution, thereby guarantee the healthy of people, in the past clinical all put into to add with the Dispoable medical syringe needle of crossing reclaim after lid container is sterilized with chlorine-containing disinfectant and ruin type.But in removal process, easily by needle sting, and need the processing of unmaking of special damaging device.

In addition, present needle tubing and needle stand are made by two kinds of unlike materials of metal and organic polymer respectively, have the hidden danger of the junction fracture of needle tubing and needle stand, so may cause fracture danger in human body of needle tubing.

Summary of the invention

The purpose of this utility model provides a kind of Dispoable medical entry needle, it can reduce fracture danger in human body of needle tubing, and after medical personnel finish injection, needle point can be burnt pin hole is closed close, needle point passivation or disappearance, so just fundamentally eliminate the possibility that medicinal liquid nubbin or disease are propagated through entry needle, and can reduce to greatest extent the risk that accident is stabbed.

The technical scheme that realizes above-mentioned purpose is: a kind of Dispoable medical entry needle, comprise that hollow needle tube and front end that needle stand, rear end are connected on the needle stand seal the sheath that also removably is enclosed within on the needle tubing, the front end of described needle tubing has a cone shape needle point, wherein, described needle stand and needle tubing are integrated and adopt the composite single injection-molded.

Above-mentioned Dispoable medical entry needle, wherein, described composite is by resin and media assemblage.

Above-mentioned Dispoable medical entry needle, wherein, described needle point forms by a ramp, a lower inclined plane that is connected with ramp and two inclined-planes, the end that are connected to the both sides of lower inclined plane, described ramp becomes the first angle α with the axes intersect of needle tubing, described lower inclined plane becomes the second angle β with the axes intersect of needle tubing, inclined-plane, the described end becomes the 3rd angle γ with the axes intersect of needle tubing, make needle point be the pointed shape of Folium Salicis Babylonicae.

Above-mentioned Dispoable medical entry needle, wherein, described the 3rd angle γ is greater than the first angle α, and described the first angle α is greater than the second angle β.

The technical scheme of Dispoable medical entry needle of the present utility model, adopt needle stand and needle tubing to be integrated, reduced fracture danger in human body of needle tubing, moreover, needle stand and needle tubing adopt composite to make, after medical personnel finish injection, needle point can be burnt pin hole is closed close, needle point passivation or disappearance, can fundamentally eliminate the possibility that remaining medicinal liquid flows out and disease is propagated through entry needle in the syringe, can also reduce to greatest extent the risk that accident is stabbed, the process that product is recycled is greatly simplified.In addition, the manufacturing of this utility model product, transportation and method of disposal are simple, economical, can substitute traditional rustless steel entry needle, be used for position liquid medicine injection, vaccine, anesthetis or venous transfusion, blood transfusion and the blood samplings such as human body is subcutaneous, Intradermal, muscle, oral cavity, also can be for the application in the fields such as animal injection.

Fig. 2 is the structural representation of the needle point of Dispoable medical entry needle of the present utility model;

Fig. 3 is the top view of Fig. 2.

The specific embodiment

In order to make those skilled in the art can understand better the technical solution of the utility model, below in conjunction with accompanying drawing its specific embodiment is described in detail:

See also Fig. 1 and Fig. 2, a kind of Dispoable medical entry needle of the present utility model comprises that hollow needle tube 2 and front end that needle stand 1, rear end are connected on the needle stand 1 seal the sheath 3 that also removably is enclosed within on the needle tubing 2, wherein,

Needle stand 1 and needle tubing 2 are integrated and adopt composite single injection-molded, this composite is by resin and media assemblage.

The front end of needle tubing 2 has a cone shape needle point 20, and this needle point 20 forms by ramp 21, a lower inclined plane 22 that is connected with ramp 21 and two inclined-planes, the end 23 that are connected to the both sides of lower inclined plane 22, makes needle point be the pointed shape of Folium Salicis Babylonicae.Ramp 21 becomes the first angle α with the axes intersect of needle tubing, lower inclined plane 22 becomes the second angle β with the axes intersect of needle tubing, inclined-plane, the end 23 becomes the 3rd angle γ with the axes intersect of needle tubing, the 3rd angle γ is greater than the first angle α, and the first angle α is greater than the second angle β.

The needle point of the pointed shape of Folium Salicis Babylonicae can improve the sharpness of needle point, reduce needle point in piercing process to the involving of patient skin tissue, thereby can reduce patient's pain.

Dispoable medical entry needle of the present utility model because needle stand and needle tubing be integrated, has reduced fracture danger in human body of needle tubing.In addition, after medical personnel finish injection, needle point can be burnt pin hole is closed close, needle point passivation or disappearance, can fundamentally eliminate the possibility that remaining medicinal liquid flows out and disease is propagated through entry needle in the syringe, can also reduce to greatest extent the risk that accident is stabbed, the process that product is recycled is greatly simplified.

Those of ordinary skill in the art will be appreciated that, above embodiment illustrates this utility model, and be not to be used as restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
