Abstract

The disclosure pertains to a perfusion system that is easy to set-up, use and monitor during a bypass procedure. In some embodiments, the disclosure pertains to a perfusion system in which 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. In some embodiments, the disclosure pertains to a blood level sensor that can be used to monitor a blood level or volume within a blood reservoir. The blood level sensor may be utilized in an integrated perfusion system in which the disposable components are configured, as noted above, to communicate with the perfusion system. In some embodiments, the blood level sensor may be utilized with a perfusion system lacking communication with disposables.

Claims

1. A method of configuring an integrated perfusion system including a heart lung machine having an RF sensor and a disposable component having an RFID tag, the method comprising steps of:

providing the RFID tag with information describing volumetric characteristics of the disposable component including sizing information;

attaching the disposable component having the RFID tag to the heart lung machine;

reading the RFID tag with the RF sensor to retrieve the volumetric characteristics of the disposable component; and

configuring operation of the heart lung machine based at least in part upon the volumetric characteristics of the disposable component retrieved by the RF sensor from the RFID tag to determine a working blood volume for the heart lung machine based on the sizing information.

2. The method of claim 1, wherein reading the RFID tag with the RF sensor comprises scanning a passive RFID tag with an RF reader.

3. The method of claim 1, wherein configuring operation of the heart lung machine comprises providing a controller, via the RF sensor, with the volumetric characteristics of the disposable component retrieved from the RFID tag by the RF sensor.

4. The method of claim 1, further comprising displaying information provided from the RFID tag to the RF sensor.

5. The method of claim 1, wherein attaching the disposable component having an RFID tag to the heart lung machine precedes reading the RFID tag with the RF sensor.

6. The method of claim 1, wherein providing the RFID tag with information describing volumetric characteristics of the disposable component includes providing the RFID tag with a minimum working volume of the disposable component.

7. The method of claim 1, wherein providing the RFID tag with information describing volumetric characteristics of the disposable component includes providing the RFID tag with a maximum working volume of the disposable component.

8. The method of claim 1, wherein providing the RFID tag with information describing volumetric characteristics of the disposable component includes providing the RFID tag with a priming volume of the disposable component.

9. A heart lung machine pack comprising:

a plurality of disposable elements including;

a tubing set having a first RFID tag secured to the tubing set, the tubing set configured for one-time use with a heart lung machine; and

a component having a second RFID tag secured to the component, the component configured for one-time use with the heart lung machine,

wherein at least one disposable element of the plurality of disposable elements has a corresponding RFID tag that contains volumetric characteristics of the at least one disposable element including sizing information to be used to determine a working blood volume for the heart lung machine; and

a housing that holds the plurality of disposable elements, wherein the housing is configured to be sealed to keep the plurality of disposable elements clean and sterile.

10. The heart lung machine pack of claim 9, wherein the component having the second RFID tag secured thereto includes one or more of a venous blood reservoir, a suction blood reservoir, a vent blood reservoir, a combined blood reservoir, an oxygenator, a heat exchanger or an arterial filter.

11. The heart lung machine pack of claim 9, wherein the first RFID tag and the second RFID tag each comprise a passive RFID tag.

12. The heart lung machine pack of claim 9, wherein the housing includes a third RFID tag that includes readable information identifying the contents of the heart lung machine pack.
