Embodiment 1

[0015] Example 1 A catheter made of a transparent and non-toxic polymer material is connected to the photosensitizer adder 2, the fluorescent irradiation bag 1, the adsorption filter 7 and the blood storage bag 10 in sequence, and the hollow part of the photosensitizer adder 2 is placed to absorb virus killers. The polyester fiber sponge body of the active agent methylene blue, the adsorption filter 7 is a flat cylinder, and the shell 14 is made of a transparent non-toxic polymer material, and is provided with microporous polyester fiber membranes 12 and 18, and the middle is The activated carbon adsorption layer 13, the liquid inlet 20 and the liquid outlet 15 are respectively located on both sides of the filter membrane, and the outsides of the two layers of microporous polyester fiber membranes are respectively provided with shunt grooves 11 and 17 made of polyester woven cloth. When the plasma to be filtered passes through the adsorption filter 7, it must pass through the l...

Abstract

This invention is a one-off virus inactivate blood transfusion filter unit, it belongs to blood processing unit technique field. It includes photosensitizer addition machine, fluorescence irradiation bag and adsorption filtration unit, and they are connected by pipe. Its feature is that the pipe communicates the three unit and blood storage bag in order. Cavernous body that can absorb virus inactivator is set at middle part of the addition machine, fiber membrane filter layer and active carbon absorbed layer is set in absorbing filter. In this invention, methylene orchid is equally added, inactivate efficiency is high, and the equipment structure is simple and reasonable. Its operation is convenient, and blood plasma pollution of each one will not happened, it can be used for medical blood filtering or blood processing in blood station.

Description

technical field [0001] The invention belongs to the technical field of blood processing devices, and in particular relates to a filter device for performing virus inactivation processing on blood plasma. Background technique [0002] Blood transfusion is one of the important means of clinical treatment. Plasma is a blood component and the main blood component in clinical blood transfusion treatment. At present, the blood plasma for clinical use in blood stations all over the country is single-serve plasma, which contains a large amount of lipid-enveloped viruses and other unstable proteins and coagulation factors, which are harmful to the health of blood recipients. In order to eliminate this hazard, the plasma must be virus inactivated. Methylene Blue (Methylene Blue) is an intravenous injection drug included in the National Pharmacopoeia. According to foreign literature reports, Methylene Blue can combine with the genome nucleic acid of the virus and the lipid envelope of...
