Hemodialysis container convenient for blood collection for nephrology department

Abstract

The invention discloses a hemodialysis container convenient for blood collection for the nephrology department. The hemodialysis container comprises a blood collection container, a blood discharge tube, a blood inlet tube, a telescopic mechanism, a blood drawing tube, a blood discharge mechanism, a blood drawing mechanism, a sampling mechanism, a driving mechanism and a mounting plate, wherein the upper end of the blood collection container, is fixedly connected with the blood inlet tube; the blood discharge tube is fixedly connected to the lower end of the blood collection container; the blood drawing tube is fixedly connected to the middle of the side wall of the blood collection container; the mounting plate is fixedly connected to the side wall of the blood collection container and is located over the blood drawing tube; and the blood discharge mechanism is arranged on the side wall of the blood collection container, and the position of the blood discharge mechanism corresponds to the position of the blood drawing tube. The hemodialysis container has the beneficial effects that ta piston plate slides in the blood drawing tube, and the blood in the blood collection container can flow into the blood drawing tube through a blood discharge hole, so that the blood can be conveniently sampled when the blood is subjected to extracorporeal dialysis circulation, a hemodialysis effect can be scientifically detected, and the treatment effect of hemodialysis circulation is ensured.

Description

technical field [0001] The invention relates to a hemodialysis container, in particular to a hemodialysis container for nephrology which is convenient for blood collection, and belongs to the technical field of hemodialysis medical equipment. Background technique [0002] Hemodialysis is to drain the blood from the body to the outside, through a dialyzer composed of countless hollow fibers, the blood and the electrolyte solution containing the same concentration as the body are inside and outside the hollow fibers, exchange substances through diffusion and convection, and remove the blood from the body. The whole process of removing excess water from the body and reinfusing the purified blood is called hemodialysis. During hemodialysis, blood collection containers are usually used outside the body. Temporarily collected after hemodialysis, and then delivered directly to the patient's body through a blood pump. [0003] However, in order to ensure that the blood is always in...

Problems solved by technology

[0003] However, in order to ensure that the blood is always in a sterile environment outside the body, the blood is completely in a sealed environment when it circulates and flows, which makes it impossible to sample the blood in the blood collection container for detection, so that it is impossible to scientifically detect the therapeutic effect after hemodialysis. To ensure the therapeutic effect of hemodialysis, and in order to sample and test blood, medical staff usually need to manually draw blood with special tools. Not only is it difficult to draw blood in a sealed blood collection container, but there is also the possibility of contamination of the blood
