Noise-reducing air passage device and its components for use in ventilator systems

A noise-reducing air passage device and its components for use in ventilator systems, configured to provide pressurized gas to an airway of a patient, the noise-reducing air passage device and its components comprising:

• a housing, including at least one inlet, at least one outlet, an inner wall, and an outer wall, wherein a space enclosed by the inner wall of the housing forms a gas passage comprising at least two chambers arranged vertically to provide the space for gas accumulation and flow;
• a blower, secured within one of the at least two chambers, having at least one inlet port and at least one outlet port, and the at least one outlet port is configured to allow flow of gas into the blower from an inlet port of the blower, pressurize the gas, and deliver the pressurized gas to the at least one outlet of the housing;
• wherein the gas passage does not include foam;
• wherein the at least one inlet of the housing is perpendicular to the at least one inlet port of the blower;
• and
• wherein the housing is configured in a way such that the at least one outlet of the housing and the at least one inlet port of the blower have a height difference along a z-axis.
