Humidification apparatus having RFID tag sensor at patient end of gas pathway
First Claim
1. A breathing circuit apparatus for the delivery of heated, humidified gases to a patient for medical purposes, comprising:
- a humidifier chamber adapted to hold a quantity of water and having an inlet and an outlet to allow gases to flow through said humidifier chamber,a blower unit adapted to in use deliver a stream of pressurised gases to the inlet of said humidifier chamber,a control system configured to adjust one or more output parameters of said breathing circuit,a heater plate which in use is located adjacent to said humidifier chamber and which is adapted to heat said quantity of water in said humidifier chamber so that said gases flowing through said chamber become heated and humidified,a gases transportation pathway connected to said outlet of said humidifier chamber to convey said gases flow to said patient, said gases transportation pathway having a patient interface adapted to supply said patient with said gases flow, said gases transportation pathway having an RFID tag located at or close to a patient end of said gases transportation pathway, said RFID tag adapted to sense a parameter of said gases passing through said gases transportation pathway,wherein said gases transportation pathway comprises a breathing conduit with an integral heater wire, said heater wire configured to provide heat to the breathing conduit and also to act as an aerial for said RFID tag,and wherein said RFID tag is configured to act as a breathing circuit component identifier, said control system having an RFID interrogator adapted to interrogate and receive data from at least one RFID tag in real time, said RFID interrogator receiving data relating to said sensed parameter and said breathing circuit component identifier, said control system adjusting the output parameters of said breathing circuit according to said received data.

Abstract
A breathing circuit for delivering heated, humidified gases to a patient for medical purposes is described, comprising a humidifier chamber holding a quantity of water, a blower unit that delivers a pressurized gases stream to the chamber inlet, and a control system that adjusts output parameters of the breathing circuit, the circuit including a heater plate which heats the water in the chamber so that gases flowing through the chamber become heated and humidified, the circuit also including a gases transportation pathway and patient interface to convey heated humidified gases to a patient, the gases transportation pathway including an RFID tag located at the patient end which senses a parameter of the gases passing through the pathway, the control system including an RFID interrogator interrogating and receiving data relating to the sensed parameter from the RFID tag in real time, and adjusting the output parameters of the breathing circuit accordingly.
