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.
Claims20
A perfusion system comprising:
- a heart lung machine;
- a blood reservoir adapted to hold a fluid, the blood reservoir having a volume determined by a geometric configuration, wherein the blood reservoir includes a communication device for communicating the geometric configuration to the heart lung machine;
- 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, the controller configured to receive the fluid level and calculate a blood volume contained within the blood reservoir, based on the fluid level and the geometric configuration;
- wherein the heart lung machine is configured to adjust an operating parameter based on the calculated blood volume.
3 more elements
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 to a level of blood within the blood reservoir;
- and
- a controller configured to receive the electrical signal from the ultrasonic sensor and output a signal indicative of a blood volume within the blood reservoir.
