Pressure monitoring system for blood component separator

Abstract

The invention provides a pressure monitoring system for a blood component separator. The system includes a blood component separator (1), a controller (2) and a pressure monitoring device (3); and thepressure monitoring device (3) is provided with a pressure sensing transducer (13), the controller (2) is in electrical connection with the blood component separator (1) and the pressure sensing transducer (13) respectively, the pressure monitoring device (3) is in sealed connection with a blood collection pipeline, a fluid channel is formed in the pressure monitoring device (3), the fluid channel is in communication with the blood collection pipeline, and the pressure sensing transducer (13) collects pressure signals of the fluid channel and outputs the signals to the controller (2). According to the system, the pressure sensing transducer is used to collect the pressure signals of the fluid channel and output the signals to the controller, so that pressure change in the pipeline can beaccurately monitored in time, and the reliability of the pressure monitoring of the blood component separator is improved.

Description

technical field [0001] The invention relates to the field of pressure monitoring of a blood component separator, in particular to a pressure monitoring system of a blood component separator. Background technique [0002] Human blood is divided into a plasma layer, a buffy coat layer, and a red blood cell layer according to different densities. Among them, the buffy coat layer can be divided into a platelet layer and a white blood cell layer. Among these blood components, the least dense is the plasma layer, and the densest is the erythrocyte layer. It is precisely according to the density of blood components that blood can be divided into different components by centrifugation technology, so as to realize the apheresis of blood components, such as apheresis of plasma, apheresis of platelets, and apheresis of red blood cells. [0003] In the process of using a blood component separator to separate whole blood, it is necessary to use a pressure monitoring device to monitor th...

Problems solved by technology

If the pressure in the pipeline is too high, it may cause the rupture of the centrifuge cup and the physical discomfort of the blood donor, and even cause a safety accident; if the pressure in the pipeline is too low, it indicates that the blood pressure of the blood donor is low, and the blood donor is not suitable for high-speed To collect blood, at this time, the peristaltic pump needs to reduce the pump speed in time to ensure the safety of blood donors and the normal progress of blood separation

However, during the use of existing pressure monitoring devices, problems such as rubber aging and cracking generally exist, which seriously affect the normal use of the pressure monitoring device; at the same time, between the air interface of the pressure monitoring device and the pressure joint of the blood collection tube There are also problems such as poor sealing, so that the pressure monitoring device cannot detect changes in the pressure in the pipeline; in addition, when installing the pressure connector of the blood collection tube, the operator needs to use a lot of force to install it in place, and the long-term operation will inevitably cause damage. Causes the operator to be easily fatigued, thereby increasing the labor intensity of the operator
