Flow generator chassis assembly with suspension seal
First Claim
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, the chassis assembly including a first chassis portion and a second chassis portion, the seal comprising:
- a chamber sealing portion configured to seal a plurality of chambers in the chassis assembly;
a blower mount with a central axis, the blower mount being configured to receive and support a portion of a blower configured to generate the flow of breathable gas;
a blower mount suspension configured to suspend the blower mount from the chamber sealing portion; and
a plurality of separate coplanar openings in the chamber sealing portion, each of the plurality of separate coplanar openings being configured to define a different part of an airflow path through the chamber sealing portion and enable communication of the flow of breathable gas between the plurality of chambers provided in the chassis assembly,wherein a first opening of the plurality of separate coplanar openings is configured to receive the flow of breathable gas from a second opening of the plurality of separate coplanar openings, andwherein a central axis of each of the plurality of separate coplanar openings is offset from the central axis of the blower mount.

Abstract
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.
