Title:
MEMBRANE OXYGENATOR HAVING BUILT-IN FILTER
Document Type and Number:
WIPO Patent Application WO/2023/284152
Kind Code:
A1
Abstract:
Disclosed is a membrane oxygenator which has a built-in filter, comprising an upper cover, a lower cover, a housing and an oxygenation structure, wherein two ends of the housing are connected to the upper cover and the lower cover respectively, and the oxygenation structure is disposed in the housing and comprises a mandrel, a filter screen, an oxygen pressure membrane and a temperature change membrane in sequence from the center to the outside. Blood flows in from an upper blood inlet of the membrane oxygenator, traverses the temperature change membrane, the oxygen pressure membrane and the filter screen in sequence, and then flows out from an blood outlet under the mandrel. During the process of transversely passing through the temperature change membrane, the oxygen pressure membrane and the filter screen, the flow rate of the blood gradually slows down, and is in full contact with the oxygen pressure membrane and the filter screen, which may improve the oxygenation effect and filtration effect of the membrane oxygenator.
