Wireless, gas flow-powered sensor system for a breathing assistance system
First Claim
1. A breathing assistance system for providing breathing assistance to a patient, comprising:
- a gas delivery system configured to generate a gas flow;
a patient interface configured to interface with the patient;
a connection system connected between the gas delivery system and the patient interface and configured to communicate the gas flow to the patient interface for delivery to the patient; and
a sensor system remote from the gas delivery system and connected to at least one of the patient interface and the connection system, the sensor system including;
a sensor for measuring a parameter of the gas flow;
a turbine configured to be driven by the gas flow; and
an electrical generator coupled to the turbine and configured to generate electricity for powering the sensor such that the sensor is powered by movement of the turbine;
wherein the sensor is located upstream from the turbine such that the turbine does not significantly affect the gas flow parameter measured by the turbine-powered sensor.
