SYSTEMS AND METHODS FOR PROVIDING LOW-NOISE POSITIVE AIRWAY PRESSURE

摘要

The systems and methods described herein include a low-noise apparatus for providing positive air pressure to a patient. The systems may include a housing with an inlet port, a vibrationally isolated blower unit positioned in an acoustic chamber, and an outlet port for delivery of the pressurized air from the blower unit. The acoustic chamber may include noise attenuators, such as walls, which adjust airflow so as to reduce the overall noise output of the system.

1. A noise attenuating system for use with ventilation or other systems providing a flow of gas comprising:
an expansion chamber having a volume; an intake tube having an inlet and outlet port separated by a length, wherein a portion of the inlet port extends outside of the expansion chamber; and a noise attenuator having a bottom and protruding sidewall forming a cavity, wherein the noise attenuator is positioned over the inlet portion of the intake tube such that a portion of the intake tube extends into the cavity portion of the noise attenuator.
