Infant venous blood collection device

Abstract

The invention discloses an infant venous blood collection device, and relates to the technical field of venous blood collection. The device comprises a console, a groove is formed in the upper surfaceof the console, the inner wall of the groove is provided with a sponge pad, a fixing plate is fixedly connected to the upper surface of the console, an elastic band is disposed on the right side surface of the fixing plate, the right end of the elastic band penetrates through a first through hole formed in the left side surface of a casing and a second through hole formed in the left side surfaceof a clamping plate, the outer wall of the elastic band respectively contacts with and presses against the inner walls of the first through hole and the second through hole, and the upper surface ofthe clamping plate penetrates through a third through hole formed in the upper surface of the casing and is located outside the casing. The infant venous blood collection device utilizes the combination of the elastic band, the casing, the first through hole, the second through hole, the clamping plate, a telescopic rod and a first spring, thereby achieving the adjustment of the binding strength of baby arms, reduces the injury of the baby arms, and provides convenience for infant venous blood collection.

Description

technical field [0001] The invention relates to the technical field of venous blood collection, in particular to an infant venous blood 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. [0003] At present, the main equipment used by infants in venous blood collection is mainly syringes. During blood collection, the baby's arm needs to be fixed. Usually, it is bound and fixed with a cuff, and the binding streng...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a baby venous blood collection device, which solves the problem that the baby’s arm needs to be fixed when taking blood. Usually, the cuff is used for binding and fixing, and the binding strength cannot be effectively adjusted. As a result, it will cause damage to the baby's arm, and in the process of taking blood from the baby's vein, the blood vessel is not fixed and shakes randomly, which will easily lead to the separation of the blood vessel and the blood vessel, thus affecting the blood collection efficiency.
