Cryoprecipitation blood coagulation factor preparation instrument and use method thereof

Abstract

The invention discloses a cryoprecipitation blood coagulation factor preparation instrument and a use method thereof, and belongs to the technical field of medical equipment. The instrument comprisesa water circulation device, a cooling and refrigerating device, a control device and a drainage cut-off device composed of a weighing device and a peristaltic pump. The components are connected together through a control system to form complete equipment. According to the invention, batch preparation, single-bag cyclic preparation and same-batch preparation of plasma (100ml, 150ml and 200ml) withdifferent specifications can be realized, the flexibility and convenience of blood station preparation operation are greatly improved, and a large amount of time can be saved. Meanwhile, the independently-driven peristaltic pump is adopted, so that the maintenance time of equipment can be greatly shortened, and the preparation efficiency is improved.

Description

technical field [0001] The patent of the invention relates to a cryoprecipitate blood coagulation factor preparation instrument, which belongs to the technical field of medical equipment, and also relates to a method for using a cryoprecipitate blood coagulation factor preparation instrument. Background technique [0002] The invention patent uses the water bath siphon method to prepare cryoprecipitate coagulation factor, and provides a stable low-temperature water bath working environment for the preparation of cryoprecipitate coagulation factor, so as to reduce the influence of external ambient temperature on cryoprecipitate coagulation factor during the preparation process. Through the control system and related intelligent accessories, the preparation process is strictly controlled, and the operation and use methods are standardized, so as to ensure that the prepared cryoprecipitate coagulation factor has high biological activity.

AI Technical Summary

Problems solved by technology

It is very difficult for users to disassemble and install during later cleaning and maintenance. The weighing box must be taken out from the stuck spring steel ball with great force, and it is easy to use too much force to increase the possibility of personal injury.

[0010] The patent [0026] with the notification number CN105399814B has a lower water tank in the second step. During the cooling process, the water in the lower water tank is in a static state and there is no water flow, so there is a problem of slow cooling speed; the water tank contains a heating device. If the control fails, it is very easy to The temperature rise exceeds the water bath control range of 1°C to 6°C, resulting in the failure of the whole batch preparation of cryoprecipitate coagulation factor
