Cryoprecipitated antihemophilic factor preparation instrument and application method thereof

Abstract

The invention discloses a cryoprecipitated antihemophilic factor preparation instrument. The cryoprecipitated antihemophilic factor preparation instrument is characterized by being composed of three parts, i.e., a weight control part, a water temperature control and water circulation system part and a central control part, wherein the three parts are interconnected together, and the weight control part is divided into a weighing part and a control part. The cryoprecipitated antihemophilic factor preparation instrument disclosed by the invention not only can achieve the simultaneous batch preparation of cryoprecipitated antihemophilic factors, but also can implement single-bag operation, i.e., the implementation of batch preparation is not required, once a bag is completely prepared, the bag can be taken out, and then a next bag is put into the instrument to prepare, so that an effect of flow production is achieved, thereby greatly saving time.

Description

technical field [0001] The invention relates to the field of cryoprecipitate blood coagulation factor preparation apparatus, in particular to a cryoprecipitate blood coagulation factor preparation apparatus, and also relates to a method for preparing and using cryoprecipitate blood coagulation factor. Background technique [0002] Cryoprecipitated coagulation factor refers to the use of a specific method to melt the fresh frozen plasma within the storage period at 1 ° C to 6 ° C, separate most of the plasma, and freeze the remaining cold insoluble substances within 1 hour to become a solid state. Component blood. Cryoprecipitated clotting factor is mainly used in patients with blood diseases, such as congenital or acquired fibrinogen deficiency, congenital or acquired coagulation factor VIII deficiency, von Willebrand's disease, children and mild adult hemophilia A etc. Cryoprecipitated coagulation factor is separated from fresh frozen plasma from whole blood by the blood ...

AI Technical Summary

Problems solved by technology

[0013] 3. The whole operation is completed in the cabinet, which leads to the large size of the whole equipment

The air cooling in the cabinet does not play a big role, but doubles the power, causing a lot of waste of electric energy.

[0014] 4. The preparation time of the air thawing method is very long, it takes more than 10 hours, and it cannot be prepared urgently

One device can only prepare one batch a day, which cannot achieve the purpose of mass production

Moreover, the quality of cryoprecipitate products prepared by air thawing is not high, and the coagulation factors in them will be inactivated due to the long preparation time

Cooled air will cause a lot of energy loss when it passes through the air duct, and it will be very imprecise to achieve a constant temperature for plasma thawing by cooling and heating the air.
