Abstract
The invention provides a miniature membrane oxygenator with a filtering function, which comprises a cylindrical shell, one end of the shell along the axial direction is provided with a liquid inlet, the other end of the shell is provided with an oxygen inlet and a liquid outlet, the shell is internally provided with a filtering assembly and an oxygenation assembly, and the filtering assembly and the oxygenation assembly are communicated through a liquid channel. The filtering assembly comprises an inner ring cylinder and an outer ring cylinder, a plurality of holes are formed in the wall surfaces of the inner ring cylinder and the outer ring cylinder, and a plurality of layers of filtering membranes which are arranged in the radial direction are arranged in a cavity between the inner ring cylinder and the outer ring cylinder; two ends of the outer ring cylinder, the filter membrane and the inner ring cylinder are respectively packaged by a first wall surface and a second wall surface; the oxygenation assembly comprises an inner ring wall and an outer ring wall, and the oxygenation film is wound on the inner ring wall and filled between the inner ring wall and the outer ring wall; and the outer sides of the oxygenation films at two ends between the inner and outer ring walls are respectively packaged by a third wall surface and a fourth wall surface. According to the micro membrane type oxygenator, the oxygenator and the filter are integrated, the structure is miniaturized and simple, and meanwhile the micro membrane type oxygenator has the low resistance performance.
