Abstract
A perfusion system that is easy to set-up, use and monitor during a bypass procedure includes at least some disposable components configured to communicate parameters to the perfusion system. An ultrasonic blood level sensor 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.
Claims18
A perfusion system comprising:
- a heart lung machine;
- a blood reservoir adapted to hold a fluid, the blood reservoir having a capacity determined by a geometric configuration, wherein the blood reservoir includes an RFID tag that includes information describing the geometric configuration of the blood reservoir;
- an ultrasonic sensor coupled to the blood reservoir and configured to determine a fluid level within the blood reservoir;
- and
- a controller coupled to the heart lung machine;
- an RFID receiver coupled to the controller, the RFID receiver configured to communicate with the RFID tag and receive from the RFID tag information describing the geometric configuration of the blood reservoir, the controller configured to receive the fluid level from the ultrasonic sensor and to receive the information describing the geometric configuration of the blood reservoir from the RFID receiver, the controller configured to calculate a blood volume contained within the blood reservoir based on the fluid level and the geometric configuration;
- a display coupled to the heart lung machine, the display configured to display the calculated blood volume;
- wherein the heart lung machine is configured to adjust an operating parameter based on the calculated blood volume.

A blood reservoir system comprising:
- a blood reservoir configured to hold a blood volume,
- an ultrasonic sensor securable to the blood reservoir, the ultrasonic sensor configured to provide an electrical signal indicative of a blood level within the blood reservoir;
- an RFID tag securable to the blood reservoir, the RFID tag configured to provide information describing the geometric configuration of the blood reservoir;
- and
- a controller configured to receive the electrical signal from the ultrasonic sensor indicative of the blood level within the blood reservoir and to receive from the RFID tag the information describing the geometric configuration of the blood reservoir, the controller configured to calculate and output a signal indicative of a blood volume within the blood reservoir.
