Title:
BLOOD OXYGENATOR WITH AN ORGANIC MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2022/113018
Kind Code:
A3
Abstract:
The object of the invention is a device for blood oxygenation, with a membrane made of an organic material of blowing properties, characterized in that it comprises of a gas exchange chamber (1) of longitudinal shape in a form of a straight cylinder or a elliptic cylinder, with passage openings (3) made at its bases (2) and (2'), provided that on one side the chamber (1) is connected in a gas-tight manner with the expansion tank (4) feeding the gas mixture containing oxygen to the chamber (1), having the inlet opening (5) of gas mixture from the feeding installation, and on the other side the chamber (1) is connected in a gas-tight manner with the gas mixture discharging tank (6) transporting it from the chamber, having the outlet opening (7) of gas mixture, and the inner part of the chamber (1) has the membrane in the form of capillary (8) bundle made of a semi-permeable material, that is permeable to gas mixture particles and non-permeable to blood particles, ends of which are anchored in the passage openings (3) in the chamber (1) bases (2) and (2') on both sides, the capillaries (8) are tensed with a tension force of a value from 1 to 100 N, preferably 10 N, and are parallel to the longitudinal axis of the chamber (1) and to each other, or are arranged spirally, that is twisted along the longitudinal axis of the chamber (1) by the same angle falling within the range from 15 to 720 degrees, preferably by the angle from 90 to 360 degrees, in addition the side wall (9) of the chamber (1) near each chamber base has at least one inlet/outlet opening (10) of blood stream, provided that the capillaries forming the membrane have the form of tubes of external diameter from 30 to 600μm, preferably 100μm.
