Non-hydrophilic membrane permeable machine for plasma leukocyte-removing filter

Abstract

The invention belongs to the field of medical instrument production, and particularly relates to a non-hydrophilic membrane water-permeable machine for a leukocyte-depleted filter. The non-hydrophilic membrane water-permeable machine comprises a water tank; one side of the water tank is connected with a high-pressure water pump; the high-pressure water pump is connected with a water-permeable tank through a water pipe; the bottom of the water-permeable tank is communicated with the water tank, the water-permeable tank comprises a tank body and a tank cover, the tank body is mounted on a bracket, the bottom of the tank body is communicated with the water tank, and the interior of the tank body is provided with a membrane supporting frame; two sides of the membrane supporting frame are each provided with a handle, the interior of the membrane supporting frame is provided with a silica gel pad, and the silica gel pad and the membrane supporting frame are each provided with a water-permeable hole; the top of the tank cover is communicated with the water pipe, and the bottom of the tank cover is provided with a pressure dividing plate; pressure plates are arranged around the pressure dividing plate; a sealing silica gel pad is arranged between the tank cover and the tank body. The non-hydrophilic membrane water-permeable machine can greatly reduce the labor intensity and improve the work efficiency, and meets the amount of a membrane material required one day with three hours of operation; the arranged pressure dividing plate and the arranged silica gel pads can ensure the cleaning quality; and the membrane supporting frame and the handles at two sides of the membrane supporting frame are convenient to use, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a non-hydrophilic membrane permeating machine for a plasma leukocyte-removing filter, which belongs to the field of medical equipment production. Background technique [0002] The plasma leukocyte-removing filter needs to use a filter membrane, which is a non-hydrophilic membrane. Before it is applied to the plasma leukocyte-removing filter, it must be permeable to make it a hydrophilic membrane, otherwise it will not be able to filter. . The current method is artificial permeation, that is, employees repeatedly rub 50 pieces of non-hydrophilic membranes in a bucket filled with purified water, then use a water press to squeeze out the water, and then repeat this process, which needs to be repeated eight times. Most of the non-hydrophilic membrane is permeable, but some corners are still not permeable, which increases the workload of the next process. This process takes ten minutes. According to the dosage of 8000 tablets / day,...

Problems solved by technology

The disadvantages of the existing membrane washing method are: labor-intensive: a lot of labor is required, and the daily production consumption consumes 8 people; labor-intensive: after a day of work, the employees are extremely tired; water-intensive: a large amount of purified water is consumed every day; The membrane material is easily damaged during the process

[0003] Since the plasma leukocyte-removing filter belongs to the third class of medical devices, the requirements for the equipment are quite high. After understanding, there is no relevant equipment in China or even abroad that can solve the production process. There are problems that need to be solved urgently

[0004] In order to solve the above problems, we have designed roller table water permeators, centrifugal water permeators, and even bought high-end washing machines for testing. Because of the disadvantages of polluted membranes, damaged membranes, and inability to achieve water permeability, we have not solved this problem.
