Automatic plasma bag cleaning and breaking system and cleaning method

Abstract

The invention provides an automatic plasma bag cleaning and breaking system and a cleaning method. The automatic plasma bag cleaning and breaking system comprises a plasma bag cleaning subsystem, a conveying mechanism and a bag feeding and breaking subsystem; the plasma bag cleaning subsystem is used for cleaning the outer portion of a plasma bag, and after cleaning is completed, the cleaned plasma bag is conveyed to the bag feeding and breaking subsystem through the conveying mechanism; the bag feeding and breaking subsystem comprises a bag feeding machine and a bag breaking machine; the bagfeeding machine is used for conveying the plasma bag to the bag breaking machine; the functions of cleaning, disinfection, tidying, sequencing and automatic loading of the plasma bag are achieved, thefunctions of plasma bag breaking, plasma pouring, liquid collecting and conveying and waste bag collecting are achieved through the bag breaking machine, the whole process is automatically completed,excessive human intervention is not needed, the problem that equipment and pipelines are cleaned after being polluted is solved, alkaline washing liquid and cleaning liquid can be recycled, and can be reasonably utilized according to the cleanliness of the plasma bag, so that water waste is avoided.

Description

technical field [0001] The invention relates to the field of pharmaceutical equipment, in particular to an automatic plasma bag cleaning and bag breaking system and cleaning method. Background technique [0002] The raw material for the production of blood products is frozen plasma stored at -20°C or below (the plasma is packed in bags, 600g / bag). Since the storage, transfer, and selection of plasma are carried out in ordinary environments, it is easy to be polluted by the external environment. Therefore, before feeding, the outer surface of the plasma bag needs to be disinfected and cleaned with ethanol 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 slurry tank, and then transferred to subsequent product production. Cleaning and disinfection of the outer surface of plasma bags is a key step in the production of blood products, which affects the quality of subsequent...

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.
