Flow generator chassis assembly with suspension seal

摘要

A seal is provided for a chassis assembly of a flow generator configured to provide a flow of breathable gas. The chassis assembly includes an upper chassis and a lower chassis. The seal includes a blower receptacle sealing portion configured to seal a blower receptacle of the chassis assembly configured to receive a blower configured to generate the flow of breathable gas; a flow sensor sealing portion configured to seal a flow sensor provided in the chassis assembly and configured to measure the flow of breathable gas; a blower mount configured to receive a portion of the blower and mount the blower to the seal; and a blower mount suspension configured to connect the blower mount to the blower receptacle sealing portion, wherein in an assembled condition the seal and the chassis assembly define a flow path from an inlet of the chassis assembly to the blower receptacle of the chassis assembly to an outlet of the chassis assembly. A flow generator for generating a flow of breathable gas includes a chassis assembly comprising a lower chassis and an upper chassis, the lower chassis and the upper chassis defining a blower receptacle; a blower provided in the blower receptacle; and the seal.

1. A seal for a chassis assembly of a flow generator configured to provide a flow of breathable gas at a continuously positive pressure with respect to ambient air pressure to an entrance of a patient's airways including at least an entrance of a patient's nares, wherein the flow generator is configured to maintain a therapy pressure in a range of about 2 cm H2O to about 30 cm H2O above ambient air pressure throughout the patient's respiratory cycle, while the patient is sleeping, to ameliorate sleep disordered breathing, the chassis assembly including an upper chassis and a lower chassis, the seal comprising:
a blower receptacle sealing portion configured to seal a blower receptacle of the chassis assembly configured to receive a blower configured to generate the flow of breathable gas; a flow sensor sealing portion configured to seal a flow sensor provided in the chassis assembly and configured to measure the flow of breathable gas; a blower mount configured to receive a portion of the blower and mount the blower to the seal; and a blower mount suspension configured to suspend the blower mount from the blower receptacle sealing portion, wherein in an assembled condition the seal and the chassis assembly define a flow path from an inlet of the chassis assembly to the blower receptacle of the chassis assembly to an outlet of the chassis assembly.
