Cryoprecipitation preparation instrument

Abstract

A cryoprecipitation preparation instrument comprises a cabinet body, plasma bags, transfer bags, a refrigeration device, a melting device and weight sensors. The cabinet body comprises a cabinet door. A middle space in the cabinet body forms an air chamber. The transfer bags are located on a working table in the middle of the cabinet body. The plasma bags are connected with the weight sensors and connected with the transfer bags through guide pipes. The plasma bags are higher than the transfer bags. The refrigeration device is composed of a compressor, a cooling pipe and a radiating pipe. The melting device comprises a draught fan, a suction pipe and an air outlet pipe. The air outlet pipe points to the position above the plasma bags located in the middle of the cabinet body. An opening of the suction pipe is connected with a heater. The heater is fixedly mounted on the working table. Clamps are arranged on the guide pipes between the plasma bags and the transfer bags. The clamps and the weight sensors are connected with an electrical control device. The cryoprecipitation preparation instrument is simple in structure and accurate in weighing, effective ingredients are low in attenuation, and full automation of the preparation process can be achieved.

Description

technical field [0001] The invention relates to equipment for preparing blood components, in particular to a cryoprecipitate preparation instrument. Background technique [0002] Cryoprecipitation is to use a specific method to thaw the fresh frozen plasma during the storage period at 1--6°C, then separate most of the plasma, and freeze the remaining cold insoluble substances in a solid state within 1 hour. Blood, whose main components are coagulation factor VIII and fibrinogen, is mainly used for the treatment of patients with hemophilia, postoperative bleeding, severe trauma, DIC, and fibrinogen and coagulation factor deficiency. At present, there are two main methods for the preparation of plasma cryoprecipitate: one is the centrifugation method, and the other is the water bath siphon method. [0003] Centrifugation method: Thaw the frozen plasma in a water bath or refrigerator at 4±2°C, take it out in time when there are still a few crushed ice cubes in the plasma, and ...
