초록 ▼

A device for treating blood in an extracorporeal blood circuit, the device including a centrifugal pump provided with a transparent enclosure that is connected, by means of an inlet duct, to the outlet of a venous reservoir, the venous reservoir having an inlet that is connected to receive blood from a patient. The transparent enclosure of the pump is connected monolithically to the base of a structure that comprises a heat exchanger and an oxygenator. The structure also supports monolithically, at the peripheral region, an arterial filter that receives the blood in output from the oxygenator and is provided with a connector for coupling to an arterial line for return of the blood to the patient.

대표청구항 ▼

1. 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; anda 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. 2. The integrated device of claim 1 wherein the blood pump comprises a centrifugal pump. 3. The integrated device of claim 2 wherein the centrifugal pump has an axis and wherein the centrifugal pump is positioned within the monolithic housing such that the axis of the centrifugal pump is horizontal. 4. The integrated device of claim 1 wherein the blood reservoir comprises a venous reservoir and a cardiotomy reservoir. 5. The integrated device of claim 4 wherein the monolithic housing comprises connection means for allowing removable connection of the first portion. 6. A system for establishing an extracorporeal blood circuit comprising: a blood reservoir;a blood pump;a heat exchanger;an oxygenator;an arterial blood filter; anda housing for incorporating and interconnecting the blood reservoir, the blood pump, the heat exchanger, the oxygenator and the arterial blood filter into a monolithic structure, the housing having an inlet for supplying venous blood to the blood reservoir and an outlet for supplying oxygenated blood from the arterial blood filter, the housing further having a portion which defines the blood pump including a blood pump inlet and a blood pump outlet, the outlet of the blood pump being located at a top of the portion such that any air bubbles in the blood will rise and be expelled through the outlet;wherein the portion of the housing defining the blood pump is transparent to permit visualization of air bubbles within the portion. 7. The system of claim 6 wherein the blood pump comprises a centrifugal pump. 8. The system of claim 7 wherein the centrifugal pump has an axis and wherein the centrifugal pump is positioned within the housing such that the axis of the centrifugal pump is horizontal. 9. The system of claim 6 wherein the blood reservoir comprises a venous reservoir and a cardiotomy reservoir. 10. The integrated device of claim 9 wherein the housing comprises connection means for allowing removable connection of the blood reservoir.
