A pressure control tube for autologous blood recovery and the use method of the pressure control tube

Abstract

The invention relates to a self-lifting blood recovery device, in particular to a pressure control tube for self-lifting blood recovery and a method for using the control tube. A pressure control tube for self-lifting blood recovery, including a pressure control tube body, the pressure control tube body includes an anticoagulation sub-pipe, a main blood tube and a liquid outlet tube, and the inlet tube is divided into an anti-coagulation sub-pipe and a blood main tube connected to a central suction device , the pressure is controlled by setting the anticoagulant film and the decompression film. Generally, it is only necessary to push the decompression push rod so that the decompression film covers the main hole of the blood, and the anticoagulation film is added to control the injection of heparin. Replace the control tube, the control tube is small and the internal space is relatively limited. If you use a general mechanical regulating valve, the cost is high, and the metal and other parts are easy to produce bacteria, so use such a membrane in the control tube, and then cooperate with disinfection. The overall cleanliness is high, and the cost is cheaper, which ensures the quality of blood recovered from self-extraction.

Description

technical field [0001] The invention relates to an autologous blood recovery device, in particular to a pressure control tube for autologous blood recovery and a method for using the control tube. Background technique [0002] Because there are certain risks in clinical blood transfusion, the use of autologous blood salvage technology in hospitals is advocated. The existing ones generally use blood storage hemofilters for autologous blood recycling, but when recycling, general hospitals use a central suction device, although the pressure can be adjusted, but because other doctors are also using it, it cannot pass the master control. If it is adjusted separately, the coming pressure will be relatively large, and the red blood cell membrane in the blood will be damaged under pressure, which will affect the quality of the blood after cleaning; and it is a single tube, without the injection of anticoagulant heparin, which will cause blood clots , also can affect the quality of ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the first purpose of the present invention is to provide a pressure control tube for autologous blood recovery that is easy to use and can be plugged into a common blood storage hemofilter. The second purpose of the present invention is to provide such a The method of controlling the use of the tube also solves the problem of controlling the amount of injected heparin
