Document Type and Number:
WIPO Patent Application WO/2024/066153
Kind Code:
A1
Abstract:
Disclosed is a membrane oxygenator blood storage tank, which comprises a housing, a cover plate, a first filter mesh bag, and a first flow guide piece. The housing is provided with a first blood storage chamber and a blood outlet. The cover plate covers an opening at the upper end of the housing. A first blood inlet is formed in the cover plate. The first filter mesh bag is arranged in the first blood storage chamber and is provided with a first blood storage cavity and a first filtering assembly arranged outside the first blood storage cavity. The first blood storage cavity communicates with the first blood inlet. The first flow guide piece is vertically arranged in the first blood storage cavity and comprises a first flow guide body and a spiral first flow guide blade arranged on the surface of the first flow guide body. The upper end of the first flow guide piece is located right under the first blood inlet. The distance from the upper end of the first flow guide piece to the first blood inlet is smaller than the distance from the upper end of the first flow guide piece to the lower end of the first filter mesh bag. The first flow guide piece can shorten a blood fall height, such that bubbles generated in the blood flowing process are reduced, the cell damage risk is reduced, and the quality of blood transfused back to a human body is improved.
