Patent ID: 8585969

Claim:
An integrated device for oxygenating and filtering blood flowing through an extracorporeal blood circuit comprising: a blood reservoir having an inlet for receiving venous blood and an outlet for supplying venous blood; a blood pump having an inlet connected to receive blood from the outlet of the blood reservoir and an outlet arranged at a top of the blood pump such that any air bubbles in the blood received from the outlet of the blood reservoir will rise and be expelled through the outlet; a heat exchanger having a blood inlet connected to receive venous blood from the outlet of the pump and a blood outlet for supplying temperature controlled venous blood; an oxygenator having an inlet connected to receive venous blood from the outlet of the heat exchanger and an outlet for supplying oxygenated blood; an arterial blood filter having an inlet connected to receive oxygenated blood from the outlet of the oxygenator and an outlet for supplying filtered oxygenated blood; and a monolithic housing including a first portion for defining the blood reservoir, a second portion for defining the blood pump, a third portion for defining the heat exchanger, a fourth portion for defining the oxygenator and a fifth portion for defining the arterial blood filter, the second portion being configured such that the outlet of the blood pump is located at a top of the second portion of the monolithic housing; wherein the second portion of the housing is transparent to permit visualization of any air bubbles within the second portion of the housing.
