Virus Inactivation Monitor

Abstract

The invention discloses a virus inactivation monitor, comprising a body, a host computer, a filter support device, a weighing device and a heat sealing device arranged on the body, and the filter support device is used for hanging in the plasma virus inactivation filtration process and supporting the blood bag; the upper position electromechanically connects the weighing device and the heat sealing device, and the weighing device is used to weigh the finished plasma bag according to the weighing instruction issued by the upper computer, and lock and weigh it after the weight of the finished plasma bag is stable. After the weight of the finished plasma bag is locked by the weighing device, the upper computer controls the heat sealing device to heat seal the inlet and outlet pipes of the finished plasma bag; the upper computer controls the weighing after the heat sealing device completes the heat sealing of the inlet and outlet pipes of the finished plasma bag. The unit releases the weight lock to weigh the next plasma product bag. The virus inactivation monitor of the present invention ensures the stability of weighing and heat-sealing operations, reduces the space occupied by the equipment, and improves the overall efficiency during the production process of the plasma product bag.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a virus inactivation monitor. Background technique [0002] In order to ensure the safety of blood use, virus inactivation treatment is required during the preparation of plasma. At present, the plasma virus inactivation method is the methylene blue photochemical inactivation method. The specific operation method is: first hang the original plasma bag on the hook plate of the inactivation bracket device, and connect it to the plasma transfer bag below through the catheter. There is a methylene blue powder box between them; then light is applied to the plasma transfer bag added with methylene blue, so that the virus completely loses its ability to penetrate, replicate and infect; after the light is completed, the plasma transfer bag is hung on the hook plate of the inactivation bracket device On the top, it is connected to the finished plasma bag below through a catheter, and a f...

AI Technical Summary

Problems solved by technology

This kind of weighing and heat sealing of plasma blood bags has the following disadvantages: 1. There are human errors in the weighing and heat sealing method. The finished plasma bag is taken away, and the next bag of plasma finished bag is weighed

2. The filter support device, weighing device and heat sealing device are separately installed in three different positions, which not only takes up space and is easy to cause messy placement, but also the operator needs to walk back and forth between the three all the time, which affects the overall efficiency
