AI Technical Summary

Technical Problem

Existing respiratory treatment devices and systems face challenges related to comfort, ease of use, manufacturability, and efficacy, particularly in the design of patient interfaces and air pressure generators, which can lead to reduced patient compliance and ineffective therapy due to discomfort, complexity, and noise.

Method used

The development of a respiratory treatment apparatus with an intermediate component that couples an air delivery tube to a respiratory treatment apparatus, featuring a sound port for acoustic analysis to identify components, a humidifier system for improved comfort, and a design that allows easy cleaning and use, including a portable RPT device with acoustic noise reduction.

Benefits of technology

Enhances patient compliance and therapy effectiveness by improving comfort, ease of use, and manufacturability, while allowing for accurate identification and timely replacement of components, thus optimizing therapy delivery.

Abstract

An apparatus for treatment of a respiratory condition, the apparatus comprising: a pressure generator configured to generate a flow of breathable gas; an intermediate component pneumatically connected to an air delivery tube, the intermediate component comprising a port configured to facilitate propagation of sound outside of the intermediate component; a sensor attached externally to the intermediate component and located adjacent to the port of the intermediate component, the sensor configured to sense sound propagated through the air delivery tube; and a controller. The controller can be configured to: receive a sound signal generated by the sensor as a result of sensing sound during operation of the apparatus, analyse the received sound signal, and effect a response based at least in part on the analysing.
