An automatic plasma bag cleaning and bag breaking system and cleaning method

Abstract

The invention provides an automatic plasma bag cleaning and bag breaking system and cleaning method, including: a plasma bag cleaning subsystem, a conveying mechanism, and a bag-loading and breaking bag sub-system; the plasma bag cleaning subsystem is used to clean the outside of the plasma bag, and the cleaning is completed Finally, the cleaned plasma bag is transferred to the bag breaking system through the conveying mechanism; the bag breaking system includes: bag loading machine and bag breaking machine; the bag loading machine is used to transfer plasma bags to the bag breaking machine; Bag cleaning and disinfection, sorting, sorting and automatic on-machine functions, the bag breaking machine realizes the functions of breaking the plasma bag, pouring out the plasma, collecting and transporting the liquid, and collecting the waste bag, and the whole process is automatically completed without too much human intervention. For the problem of cleaning equipment and pipelines after their own pollution, the alkali washing solution and cleaning solution can be recycled and reused, and can be rationally used according to the cleanliness of the plasma bag, avoiding waste of water.

Description

technical field [0001] The invention relates to the field of pharmaceutical equipment, in particular to an automatic blood plasma bag cleaning and bag breaking system and a cleaning method. Background technique [0002] The raw material for the production of blood products is frozen plasma stored at -20°C and below (plasma is in bags, 600g / bag). Since the storage, transfer, and selection of plasma are all carried out in ordinary environments, they are easily polluted by the external environment. Therefore, before feeding, the outer surface of the plasma bag needs to be ethanol-sterilized and cleaned to remove microorganisms and pyrogens on the outer surface of the plasma bag. Then, the plasma bag is broken open, and the plasma in the bag is melted in the melting tank and transferred to subsequent product production. Cleaning and disinfection of the outer surface of the plasma bag is a key step in the production of blood products, which affects the quality of subsequent produ...

AI Technical Summary

Problems solved by technology

The plasma bag is pre-washed with water for injection to remove surface ice residue, then fished out, placed flat on the conveyor belt of the plasma cleaning machine, and then undergoes spray rough cleaning, disinfection (75% ethanol), fine cleaning, and compressed air blowing in sequence according to the set speed. After being cleaned, it is transferred to the slurry melting room for bag breaking. The cleaning process uses a large amount of water for injection, and the equipment itself is cleaned manually, so it is difficult to guarantee the cleaning effect

[0003] In the prior art, a cleaning and disinfection machine for automatic cleaning and disinfection of blood plasma bags is mentioned, which avoids manual work. Reasonable utilization leads to waste of water for injection;

[0004] Moreover, due to the possibility of the plasma bag being broken during use, the equipment will be polluted by the plasma, and the problem of cleaning the equipment and the pipeline itself after contamination cannot be completely solved.
