Abstract
A noise-reducing air passage device and its components for use in ventilator systems, including a housing with at least one inlet, at least one outlet, an inner wall, and an outer wall. The space enclosed by the inner wall of the housing forms a gas passage including at least one chamber to provide a space for gas accumulation and flow. A blower, the core component to provide positive pressure gas to the device, is secured within one of the at least one chamber. The gas passage also includes a ventilation component to divide the gas and streamline turbulent airflow. The ventilation component is among the noise-reducing components, which also include a support component to provide support and damp vibrations for the blower and an inlet component provided at the inlet.
Claims25
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 one chamber to provide the space for gas accumulation and flow;
- a blower, secured within one of the at least one chamber, wherein the blower has at least one inlet port and at least one outlet, and is configured to allow flow of gas into the blower from the at least one inlet port, pressurize the gas, and deliver the pressurized gas to the at least one outlet of the housing;
- at least one ventilation component, wherein the at least one ventilation component is provided within the gas passage and is configured to divide at least part of the gas;
- and
- at least one support component, configured as a perforated elastomer, wherein the at least one support component is provided within the at least one chamber to support the blower and to disperse vibrations during operation of the blower,
- wherein a longitudinal axis of the at least one inlet of the housing transversely intersects a longitudinal axis of the at least one outlet of the blower in a top view plane, wherein the longitudinal axis of the at least one inlet and the longitudinal axis of the at least one outlet are both only oriented horizontally, and
- wherein the housing is configured in a way such that the at least one outlet is at a higher elevation than the at least one inlet port along a z-axis.
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 one chamber to provide the space for gas accumulation and flow;
- and
- a blower, secured within one of the at least one chamber, having at least one outlet, and 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 housing is configured to be connected to the at least one outlet of the blower through at least one external component;
- wherein the gas passage does not include foam;
- and
- wherein a longitudinal axis of the at least one inlet of the housing transversely intersects a longitudinal axis of the at least one outlet of the blower in a top view plane, wherein the longitudinal axis of the at least one inlet and the longitudinal axis of the at least one outlet are both only oriented horizontally, and
- wherein the housing is configured in a way such that the at least one outlet and the at least one inlet port have a height difference along a z-axis.
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 one chamber to provide the space for gas accumulation and flow;
- and
- a blower, secured within one of the at least one chamber, 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 at least one inlet and at least one outlet of the housing are provided on different wall surfaces;
- wherein a structure of the at least one chamber is configured to divert airflow and reduce noise as the gas passes through;
- wherein the gas flow path includes a segment of a vertical path configured to be at least 20 mm;
- wherein a longitudinal axis of the at least one inlet of the housing transversely intersects a longitudinal axis of the at least one outlet of the blower in a top view plane, wherein the longitudinal axis of the at least one inlet and the longitudinal axis of the at least one outlet are both only oriented horizontally;
- and
- wherein the housing is configured such that the at least one outlet and the at least one inlet have a height difference along a z-axis.
