Pressure control pipe for autologous blood transfusion and use method for pressure control pipe

Abstract

The invention relates to an autologous blood transfusion instrument and especially relates to a pressure control pipe for autologous blood transfusion and a use method for the pressure control pipe. The pressure control pipe for autologous blood transfusion comprises a pressure control pipe main body, wherein the pressure control pipe main body comprises an anti-coagulation branch pipe, a main blood pipe and a blood outlet pipe; an inlet pipe is divided into the anti-coagulation branch pipe and the main blood pipe and is connected with a central attracting device; an anti-coagulation film and a pressure-reducing film are arranged for controlling the magnitude of pressure; under a general condition, a pressure-reducing push rod is pushed, a main blood hole is covered by the pressure-reducing film and the control of the anti-coagulation film on heparin injection is enhanced, so that only a control pipe is exchanged; the control pipe is small and the inner space of the control pipe is limited, and if a general mechanical adjusting valve is used, the cost is high and bacteria are easily generated on metal parts; the film is used in the control pipe and the disinfection is performed, so that the whole cleanliness is high, the cost is lower and the blood quality of the autologous blood transfusion is ensured.

Description

[0001] technical field [0002] 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. Background technique [0003] Because there are certain risks in clinical blood transfusion, it is recommended that hospitals use self-collection blood recovery technology. The existing blood collection device is generally used for self-extraction blood recovery, but when recycling, the general hospital uses a central suction device, although the pressure can be adjusted, but because other doctors are also using it, it cannot be passed through the total suction device. If the control is adjusted separately, the coming pressure will be relatively large, and the red blood cell membrane in the blood will be damaged due to the pressure, which will affect the quality of the blood after cleaning; and it is a single tube, without the injection of anticoagulant heparin, which w...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the first purpose of the present invention is to provide a pressure control tube that is easy to use and can be plugged into an ordinary blood storage blood filter for self-extraction blood recovery. The second purpose of the present invention is to provide this The use method of a control tube solves the problem of controlling the amount of injected heparin at the same time
