Protective infectious disease blood sample collection device

Abstract

The invention discloses a protective infectious disease blood sample collection device which comprises an outer cylinder, an inner rod, an inner rod channel, a blood collection bottle connecting pipe, a piston ring, a first conical sealing ring, a first sealing ball, a first spring, a first spring ring seat, a second conical sealing ring, a second sealing ball, a second spring and a second spring ring seat. Compared with the prior art, by means of the protective infectious disease blood sample collection device, continuous blood collection is achieved through a small-specification syringe, the blood collection time is saved, a needle head is not pulled out in the blood collection process, when a needle tube stops blood collection, the part of the needle head is sealed through a sealing ball, infectious disease bacterial contamination in air is prevented, inaccurate inspection results are prevented, and application and popularization value is achieved.

Description

technical field [0001] The invention relates to a medical device, in particular to a protective infectious disease blood sample collection device. Background technique [0002] Phlebotomy is a method of drawing a certain amount of venous blood through a needle tube. Superficial veins located on the body surface are mostly used, usually the elbow vein, dorsal hand vein, medial malleolus vein or femoral vein. Children can take blood from the external jugular vein. Different types of syringes can be selected according to the amount of blood collected, and corresponding needles can be equipped. For some special examinations, in order to avoid platelet activation, plastic syringes and siliconized test tubes or plastic test tubes should be used. In the prior art, blood collection is mostly done through a syringe, and the amount of blood collection required is relatively large, so it is troublesome to collect multiple times. In addition, after the collection, the syringe is pull...

AI Technical Summary

Problems solved by technology

In the prior art, blood collection is mostly done through a syringe, but if the amount of blood collection is slightly larger, multiple collections are more troublesome. In addition, after the collection, the syringe is pulled out, and the needle part is exposed to the environment, which may be infected by airborne infectious diseases. Bacterial contamination, leading to inaccurate test results, therefore, there is room for improvement
