Blood oxygenator with an organic membrane

A device for blood oxygenation, with a membrane made of an organic material of blowing properties, comprising:

• a gas exchange chamber of longitudinal shape in a form of a straight cylinder or a elliptic cylinder, with passage openings made at its bases, provided that on one side the chamber is connected in a gas-tight manner with the expansion tank feeding the gas mixture containing oxygen to the chamber, having the inlet opening of gas mixture from the feeding installation, and on the other side the chamber is connected in a gas-tight manner with the gas mixture discharging tank transporting it from the chamber, having the outlet opening of gas mixture, and the inner part of the chamber has the membrane in the form of capillary bundle, uniformly distributed inside the chamber, wherein capillaries are comprised 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 in the chamber bases on both sides, the capillaries are tensed with a tension force of a value from 1 to 100 N, and are parallel to the longitudinal axis of the chamber and to each other, or are arranged spirally, that is twisted along the longitudinal axis of the chamber by the same angle falling within the range from 15 to 720 degrees, in addition the side wall of the chamber near each chamber base has at least one inlet/outlet opening of blood stream, provided that the capillaries forming the membrane have the form of tubes of external diameter from 30 to 600 μm,
• wherein the capillaries forming the membrane are comprised of an organic material of blowing properties, anti-inflammatory properties and antithrombotic properties, the organic material consisting of:
• base in the form of polypropylene (PP) or polyurethane (PU) or polyethylene terephthalate (PET) or polycarbonate (PC) polyoxymethylene (POM) or polysulphone (PSU) or fluoric silicone or polytetrafluoroethylene (PTFE) or polyvinylidene fluoride (PVDF) or copolymer of hexafluoropropylene and tetrafluoroethylene (FEP),
• admixture of 4-(diphenylamino)benzaldehyde in the base-admixture ratio from 50÷1 to 5000÷1, and
• admixture of 1,3-indandione in the base-admixture ratio from 50÷1 to 5000÷1.
