Abstract

A perfusion system is easy to set-up, use and monitor during a bypass procedure. At least some of the disposable components used with the perfusion system are configured to be able to communicate set-up and/or operational parameters to the perfusion system. A blood level sensor can be used to monitor a blood level or volume within a blood reservoir.

Claims

1. An integrated perfusion system comprising:

a disposable element, the disposable element including an RFID tag that is programmed with information describing volumetric operational settings of the disposable element; and

a heart lung machine including

a plurality of pump modules, each pump module including a control unit;

a controller in communication with each of the pump module control units;

an input device in communication with the controller and configured to accept operational settings information from a user;

an output device in communication with the controller and configured to display operational parameters of the plurality of pump modules; and

an RF sensor in communication with the controller, the RF sensor configured to retrieve the information describing volumetric operational settings of the disposable element from the RFID tag and communicate the information to the controller;

wherein the controller uses the information describing volumetric operational settings of the disposable element to determine a working blood volume for the heart lung machine.

2. The integrated perfusion system of claim 1, wherein the disposable element comprises tubing.

3. The integrated perfusion system of claim 1, wherein the disposable element comprises one or more of a blood reservoir, an oxygenator, a heat exchanger, or an arterial filter.

4. The integrated perfusion system of claim 3, wherein the blood reservoir comprises a venous blood reservoir, a suction blood reservoir, a vent blood reservoir or a combination thereof.

5. The integrated perfusion system of claim 1, wherein the RFID tag comprises a passive RFID tag.

6. The integrated perfusion system of claim 1, wherein the RF sensor comprises a hand-held RFID reader.

7. The integrated perfusion system of claim 1, wherein the input device comprises a touch screen computer.

8. The integrated perfusion system of claim 1, wherein the volumetric operational settings include a minimum working volume of the disposable element.

9. The integrated perfusion system of claim 1, wherein the volumetric operational settings include a maximum working volume of the disposable element.

10. The integrated perfusion system of claim 1, wherein the volumetric operational settings include a priming volume of the disposable element.

11. The integrated perfusion system of claim 1, wherein the RFID tag comprises a passive RFID tag.

12. The integrated perfusion system of claim 1, wherein the RF sensor comprises a hand-held RFID reader.

13. The integrated perfusion system of claim 1, wherein the input device comprises a touch screen computer.

15. The integrated perfusion system of claim 1, wherein the disposable element comprises tubing.

16. The integrated perfusion system of claim 1, wherein the disposable element comprises one or more of a blood reservoir, an oxygenator, a heat exchanger, or an arterial filter.

17. The integrated perfusion system of claim 16, wherein the blood reservoir comprises a venous blood reservoir, a suction blood reservoir, a vent blood reservoir or a combination thereof.

14. An integrated perfusion system comprising:

a disposable element, the disposable element including an RFID tag that is programmed with information describing volumetric operational settings of the disposable element, the volumetric operational settings including one or more of a minimum working volume or a priming volume of the disposable element; and

a heart lung machine including

a plurality of pump modules, each pump module including a control unit;

a controller in communication with each of the pump module control units;

an input device in communication with the controller and configured to accept operational settings information from a user;

an output device in communication with the controller and configured to display operational parameters of the plurality of pump modules; and

an RF sensor in communication with the controller, the RF sensor configured to retrieve the information describing volumetric operational settings of the disposable element from the RFID tag and communicate the information to the controller;

wherein the controller uses the information describing volumetric operational settings of the disposable element to regulate operation of the heart lung machine.
