Problems solved by technology

However, the current method of heat preservation when preparing cryoprecipitate is to use ice and ice water to maintain a constant temperature of 0°C to 4°C. This method is laborious and time-consuming, and the temperature is not easy to control, and the quality of the product is not easy to guarantee.

Abstract

The cold precipitating preparation instrument includes heat insulating refrigerator, 0-4 deg.c constant temperature control circuit, weight sensing control circuit, display circuit and alarm circuit. The using process includes turning on the power switch to start the heat insulating refrigerator, setting frozen plasma on the weight sensor and transferring bag in the plasma bag groove in the position lower than that of the frozen plasma, and transferring thawed plasma to the transferring bag owing to gravitational force and siphonage. When the residual plasma is reduced to 50 g, the weight sensing circuit and the alarm circuit operate to send out warning signal to show the finish of the cold precipitating preparation process and the relevant information is shown in the LCD. During the whole process, the temperature of plasma is controlled in 0-4 deg.c to ensure the quality and activity of plasma.

Description

technical field [0001] The invention relates to an instrument used in the preparation of cryoprecipitate, a blood product used for component blood transfusion in blood banks and hospitals. Background technique [0002] In the process of component blood transfusion in blood banks and hospitals, a special kind of component blood transfusion is the use of cryoprecipitate preparation. This cryoprecipitate is mainly used for blood component transfusion in hemophiliac patients. At present, cryoprecipitation technology is widely used in blood banks and has made great contributions to the treatment of hemophilia patients. However, the current method of heat preservation when preparing cryoprecipitate is to use ice and ice water to maintain a constant temperature of 0°C to 4°C. This method is laborious and time-consuming, and the temperature is not easy to control, and the quality of the product is not easy to guarantee. Contents of the invention [0003] The purpose of the prese...
