Safe and efficient blood component retransfusion and collection control device

Abstract

A safe and efficient blood component retransfusion and collection control device comprises a retransfusion pump and a pump pipe thereof, a blood collecting pump and a pump pipe thereof, control boxes, an ultrasonic high liquid level detector, an ultrasonic low liquid level detector, a time controller and a machine frame, wherein the control boxes are welded by a transparent polymer material to form a sealed retransfusion container and a plurality of channels; the channels are communicated with soft pipes and connectors to form a sealed disposable integral component which is installed on the machine frame; the machine frame is installed on an operating table of a blood separator, and forms an included angle of 45 degrees with the horizontal plane; the ultrasonic high liquid level detector and the ultrasonic low liquid level detector are tightly adhered to one control box through assembling holes reserved on the machine frame; the retransfusion pump, the blood collecting pump, the main body of the ultrasonic high liquid level detector and the main body of the ultrasonic low liquid level detector are installed inside the housing of the blood separator; and sensing circuits of the ultrasonic detectors and a control circuit of the time controller are serially connected and then connected with the retransfusion pump. The safe and efficient blood component retransfusion and collection control device not only can collect and return blood uninterruptedly to improve the working efficiency and the comfort of a blood donor, but also has dual protection functions and can avoid pumping air into the body of the blood donor.

Description

technical field [0001] The invention relates to a medical device, in particular to a safe and efficient blood component reinfusion and collection control device applied in the field of blood component collection. Background technique [0002] At present, human blood donation is still the main source of medical blood. When donating blood, often only one or several specific blood components are needed, such as plasma, platelets, red blood cells, etc., while other components can be transfused back to the blood donor to avoid waste of blood resources and reduce adverse reactions of blood transfusion. Therefore, in modern blood donation technology, the method of separating and collecting blood components is often used, that is, the whole blood collected by the blood donor is separated into different components, the required components are taken out, and then the remaining components are returned to the blood donor. . [0003] Existing blood component separators (such as CS-3000...

AI Technical Summary

Problems solved by technology

[0003] Existing blood component separators (such as CS-3000 and NGL XCF-3000 blood component separators) do not have reinfusion containers and high and low liquid level automatic control conversion devices, so the reinfusion, separation and collection of blood components are carried out separately and intermittently Yes, the separation of blood components cannot be carried out at the same time when unnecessary blood components are returned to the blood donor
