WIRELESS, GAS FLOW-POWERED SENSOR SYSTEM FOR A BREATHING ASSISTANCE SYSTEM

摘要

A breathing assistance system (10) for providing breathing assistance to a patient (12) includes a gas delivery system (14) configured to generate a gas flow, a patient interface (16) configured to interface with the patient (12), a connection system (18) connected between the gas delivery system (14) and the patient interface (16) and configured to communicate the gas flow to the patient interface (16) for delivery to the patient (12), and a sensor system (20) remote from the gas delivery system and connected to at least one of the patient interface (16) and the connection system (18). The sensor system (20) may include a sensor (26) for measuring a parameter, one or more actuators (42), and a power supply based on a turbine (28) configured to be driven by the gas flow and an electrical generator (30) coupled to the turbine (28) and configured to generate electricity.
