AMBULATORY LUNG ASSIST DEVICE WITH IMPLANTED BLOOD PUMP AND OXYGENATOR

摘要

The present disclosure provides a system for oxygenating blood. The system may include an implantable blood pump that may draw a supply of blood from the circulatory system of a mammalian subject, such as a human being. The blood pump may provide the supply of blood to an adaptor, where the supply of blood may be supplied to either or both of a first branch or second branch. The first branch may lead to an external blood oxygenator. The oxygenator may oxygenate the blood, and the blood may be returned to the circulatory system of the mammalian subject. The second branch may bypass the oxygenator and may connect to the circulatory system of the mammalian subject. In this regard, while the blood is supplied to the second branch, the oxygenator may be disconnected and blood may be prevented from entering the first branch.

主权项

1. A portable lung assist system comprising:
(a) a blood pump, wherein the blood pump has an outlet and an inlet adapted for communication with the circulatory system of a mammalian subject at an inlet location, and wherein the blood pump can be carried by a subject; (b) one or more return fittings adapted for communication with the circulatory system of the subject at one or more return locations remote from the inlet location; (c) an external, portable blood oxygenator having a blood inlet releasably connectable and which is in communication with the outlet of the pump and a blood outlet releasably connectable with one of said return fittings; and (d) a bypass conduit adapted to connect the outlet of the blood pump in communication with one of said return fittings at least when the oxygenator is disconnected, wherein the portable lung assist system supplements the action of the subject's lungs.
