Venous blood sampling auxiliary device

Abstract

The invention discloses a venous blood sampling auxiliary device which comprises a box and a hand placement table. A pressurizing bandage box is arranged at the top of the box. A supporting base plateis arranged at the bottom of the inner side of the box, a supporting spring is arranged at the top of the supporting base plate, a gasket placement plate is arranged at the top of the supporting spring, a roller support is fixedly connected to the inner side of the box, a conveying roller is installed in the middle of the roller support, a blood sampling pad is placed at the gasket placement plate, a lifting regulating motor is fixedly connected to one side inside the box, a threaded shaft is installed at the output shaft of the lifting regulating motor through a coupler, and a movable sliding sleeve is installed at the outer side of the threaded shaft. The invention relates to the technical field of venous blood sampling. According to the venous blood sampling auxiliary device, the purpose of automatically replacing the blood sampling pad is achieved, due to the fact that it is quite troublesome that an execution rod replaces the blood sampling pad in the actual venous blood samplingwork, workloads of doctors can be reduced by automatically replacing the blood sampling pad, and blood sampling work can be conveniently performed.

Description

technical field [0001] The invention relates to the technical field of venous blood collection, in particular to an auxiliary device for venous blood collection. 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 collect blood from the external jugular vein, and different types of syringes can be selected according to the blood collection volume, equipped with corresponding needles. For some special examinations, in order to avoid platelet activation, plastic syringes and siliconized test tubes or plastic test tubes should be used. Now venous blood collection requires one person, one needle, one tube, and one pad. It is too troublesome to implement in actual work. Now the pad is replaced. Too much trouble.
