Abstract

The utility model relates to the technical field of medical instruments, in particular to a novel disposable blood taking needle. The novel disposable blood taking needle comprises a scalp needle (1), a needle head (2), a rubber bush (3), a Y-shaped three-way valve (4) and a heparin cap (5), wherein the tail part of the scalp needle (1) is connected with the Y-shaped three-way valve (4) , the heparin cap (5) is mounted at the free end of the Y-shaped three-way valve (4), the other tail end of the Y-shaped three-way valve (4) is connected with the needle head (2), and the rubber bush (3) is nested outside the needle head (2). The novel disposable blood taking needle has the characteristics that when the blood of a patient is taken, the patient suffers from the circulatory failure and macilency, or the negative pressure of a blood taking pipe is insufficient, a vacuum needle can be directly used for taking blood from the heparin cap, and the scalp needle can be fixed and then used for venous transfusion, thereby avoiding the punctures; and the novel disposable blood taking needle has the advantages of reasonable structure, simplicity in operation, time and labor conservation, and the like.

Description

A kind of novel disposable blood taking needle

Technical field

This utility model relates to a kind of technical field of medical instruments, specifically a kind of novel disposable blood taking needle.

Background technology

The disposable blood taking needle that present blood sample collection clinically uses, front end is a scalp acupuncture, end is a syringe needle, rubber case of syringe needle overcoat, after the venipuncture success syringe needle of afterbody band rubber case is inserted in the negative pressure blood taking tube during blood sampling, extract when waiting blood to flow into requirement and thrust another blood taking tube again, do not waste blood like this, operate and more convenient better effects if when especially the blood sample collection amount is more.But under special circumstances, as: the patient circulate the extreme exhaustion, become thin, situation under, under the insufficient situation of perhaps disposable blood taking tube negative pressure, blood is just to having outflowed when using the not enough blood volume of disposable blood taking needle collection, have to extract blood taking needle,, so both increase patient's misery again with disposable syringe puncture blood drawing, increased staff's workload again, brought very big inconvenience to work.

Summary of the invention

In order to overcome above-mentioned defective, this utility model provides a kind of rational in infrastructure, a kind of novel disposable blood taking needle of simplifying the operation.The technical solution adopted in the utility model is: a kind of novel disposable blood taking needle, comprise scalp acupuncture, syringe needle, rubber case, the threeway of Y shape and calparine cap, afterbody at described scalp acupuncture is connected with the threeway of Y shape, the free-end of Y shape threeway is equipped with calparine cap, the terminal syringe needle that connects of another of Y shape threeway, rubber case is equipped with in the outside of syringe needle.

This utility model will add threeway of a Y shape and calparine cap on the blood taking needle, be convenient to the staff when blood sampling as running into special circumstances, as: patient circulate the extreme exhaustion, become thin, when the blood taking tube negative pressure is not enough, can directly draw blood from calparine cap with empty needle, be used for venous transfusion after also scalp acupuncture can being fixed, avoid the repetition venipuncture, time saving and energy saving, alleviate characteristics such as patient suffering.
