Abstract
The utility model relates to the field of medical instruments, in particular to a syringe with a needle head self-unloading device. The syringe with the needle head self-unloading device is composed of a needle barrel, a piston, a pushing rod, a pushing handle, a needle seat, a needle head and a needle cap, wherein the needle seat is a frustum body with a through hole, and the needle head is connected with the needle seat through a pintle. The syringe with the needle head self-unloading device is characterized by further comprising a needle head self-unloading piece with a connection hole, a connection rod and a handle, wherein the needle head self-unloading piece is sleeved on the needle seat behind the pintle through the connection hole, one end of the connection rod is connected with one side of the needle head self-unloading piece, and the other end of the connection rod is connected with the handle. Due to the fact that the syringe with the needle head self-unloading device is provided with the needle head self-unloading piece, when the needle head needs unloading, a medical worker holds the needle barrel tightly, pushes the handle forward through a thumb, the needle head self-unloading piece is twisted on the needle seat and then automatically unloads the needle head, if the needle head self-unloading piece falls off the needle seat, the needle head self-unloading piece can not fall onto the ground under the action of a falling-prevention connection line, the operator holds the handle by hand, and enable the needle head self-unloading piece to install the needle head on the needle seat, the medical worker is completely prevented from being punctured and being infected by virus when unloading the needle head.
Description
Technical field
This utility model relates to medical apparatus and instruments, specifically a kind of easy to operate, use safety, can avoid medical personnel owing to unloading the be wounded by stabbing syringe with the self-unloading needle apparatus of the viral infection that causes of syringe needle.
Background technology
We know, the clinical medical and nursing personnel are because using syringe to cause the probability of viral infection higher, syringe is by syringe, piston, push rod, needle stand, syringe needle and pin medicated cap form, needle stand is one to be provided with the cone table of through hole, syringe needle is connected with needle stand through pintle, when needs unload syringe needle, medical personnel want one to hold tight needle tubing, another hand channel cone table cover unloads syringe needle, in operation, medical personnel be easy to careless and hands by needle sting, cause the antibacterial in the power patient blood, the viral infection medical personnel, people have invented multiple disposable syringe for this reason, but at some particular places, during such as prophylactic immunization, the medicinal liquid of a syringe will carry out multiple injection, so must change the syringe needle of syringe.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of easy to operate, use safety, fringe cost at the bottom of, can avoid medical personnel owing to unloading the be wounded by stabbing syringe with the self-unloading needle apparatus of the viral infection that causes of syringe needle.
This utility model can reach by following measure:
A kind of syringe with the self-unloading needle apparatus, by syringe, piston, push rod, push away handle, needle stand, syringe needle and pin medicated cap and form, needle stand is one to be provided with the cone table of through hole, syringe needle is connected with needle stand through pintle, it is characterized in that being provided with syringe needle with connecting hole from unloading piece, connecting rod and handle, syringe needle is on the needle stand of unloading piece after connecting hole is enclosed within pintle, and an end of connecting rod is connected with a side of syringe needle self-unloading device sheet, and the other end is connected with handle.
This utility model can be provided with the anticreep connecting line, and an end of anticreep connecting line is connected with handle, and the other end is connected with the rearward end of push rod, and is contaminated to prevent syringe needle self-unloading sheet from falling to the ground.
This utility model is owing to be provided with syringe needle from unloading piece, when needs unload syringe needle, the syringe as long as medical personnel hold with a firm grip, with thumb driving handle forward, twisting occurs from unloading piece at needle stand syringe needle is unloaded automatically in syringe needle, if syringe needle is from the unloading piece needle stand that comes off, syringe needle can not land from unloading piece yet under the effect of anticreep connecting line, the hand-held handle of operator is loaded onto syringe needle from unloading piece at needle stand with syringe needle and is got final product, have novel structure, easy to operate, use safety, increase the advantages such as cost is few, thoroughly avoided medical personnel owing to the viral infection that unloads syringe needle and be wounded by stabbing and cause.
