Abstract
A process includes removing air bubbles from extracorporeal blood via chemical entrapment of nitrogen (N2) gas.
Claims20
An article of manufacture including a housing for treatment of extracorporeal blood, the housing comprising a blood inlet component and a blood outlet component for circulating the extracorporeal blood;
- wherein the housing contains an organometallic complex bound to a surface of a particle, the organometallic complex being a titanium complex that is capable of binding with nitrogen (N2) gas, the organometallic complex being capable of removing air bubbles from the extracorporeal blood via chemical entrapment of the nitrogen (N2) gas.
A drip chamber comprising:
- a housing for treatment of extracorporeal blood, the housing comprising a blood inlet component and a blood outlet component for circulating the extracorporeal blood;
- and
- an air bubble removal component comprising an organometallic complex bound to a surface of a particle, wherein the organometallic complex is a titanium complex that is capable of binding with nitrogen (N2) gas, the organometallic complex being configured to remove air bubbles from the extracorporeal blood via chemical entrapment of the nitrogen (N2) gas,
- wherein the air bubble removal component is disposed within the housing between the blood inlet component and the blood outlet component.
