Abstract

The utility model provides a disposal test tube blood taking needle, and belongs to the technical field of medical appliances. The blood taking needle consists of a test tube, a seal plug, a puncture head, a guide pipe, a rubber cap, a piston and a pintle, and is characterized in that: the seal plug in the opening end of the test tube is provided with the guide pipe which is communicated with the cavity of the test tube and connected with the puncture head at outer end; the rubber cap capable of sealing the outer end of the guide pipe is connected with and fixed on the outer wall of the opening end of the test tube through a soft strip; the front end of the pintle passes through the bottom of the test tube and the through hole corresponding to the test tube, and is fixedly connected with the piston in the test tube; and a fracture groove is formed on the pintle close to the rear end face of the piston. The disposal test tube blood taking needle has a simple structure, convenience for operation and time and labor saving, so that secondary transfer is not required when the collected blood is saved or detected, a blood sample cannot be polluted, the inspection accuracy is improved, and the working difficulty of medical staff is reduced.

Description

Disposable test blood sampling tube pin

Technical field

This utility model belongs to technical field of medical instruments, specifically a kind of disposable test blood sampling tube pin.

Background technology

At present, take a blood sample with disposable syringe usually clinically, thrust veins beneath the skin to piercing needle during blood sampling; Re-inject the usefulness of test tube behind the blood sample collection, so operate cumbersomely, waste time and energy for check; But also increased the contaminated risk of blood sample; Reduced the accuracy of check, even made the check failure sometimes, had to draw blood again.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of blood sample of gathering can directly get into test tube, blood sample need not the disposable test blood sampling tube pin of secondary transferring.

The purpose of this utility model is achieved in that this disposable test blood sampling tube pin is made up of test tube, sealing-plug, piercing needle, conduit, rubber cap, piston, pintle; Sealing-plug in the test tube opening end is provided with the conduit that the outer end that communicates with the test tube inner chamber is connected with piercing needle, and test tube opening end outer wall is being fixed through soft band connection can be with the rubber cap of conduit outer end sealing; The pintle front end is fixedly linked with invisible spectro piston after passing the through hole that test tube bottom adapts with it, on the pintle near piston rear end face place, is provided with the groove that fractures.

After blood sampling finishes pintle is fractureed from the groove that fractures, unload piercing needle then, with rubber cap conduit is sealed at last, test tube can become the container that holds blood sample like this.

The utility model has the advantages that: simple in structure, easy and simple to handle, time saving and energy saving, need not secondary transferring when the blood file of collection or detection, can not pollute blood sample, improve the check accuracy rate, alleviate medical worker's work difficulty.
