Respiratory humidification system
First Claim
1. A breathing circuit component or connector for interconnection with a breathing assistance apparatus and having an interior defining a longitudinal axis for conveying respiratory gas, said breathing circuit component or connector capable of receiving an associated sensor, said breathing circuit component or connector comprising:
- a sensor entry port extending perpendicularly from said component or connector and configured to receive the sensor, said sensor entry port being defined by a wall, anda locating notch extending from said wall, said locating notch configured to receive a complementary locating tooth from the sensor, the interconnection of said notch and a tooth providing a predetermined orientation of the sensor which is fixed relative to the longitudinal axis.

Abstract
A flow probe for use in a humidification system is positioned in a humidified gases flow such as that which is provided to a patient in a hospital environment. The flow probe is designed to provide both temperature and flow rate sensing of the gases flow by incorporating two sensors into the gases flow. The flow probes are shaved and aligned within the gases flow to enable accurate gas flow readings to be taken whilst reducing the occurrence of condensation on the sensors. The flow probe can also be included in a humidification control systems to provide a patient with a desired humidity level or simplify the amount of user input required to set humidity levels. Furthermore, the flow probe can provide a controller with flow information which may then be used to determine certain conditions that could prove to be dangerous to a patient.
