Abstract

Apparatus for generating a supply of air at positive pressure for the amelioration or treatment of a respiratory disorder, comprising: a first chamber; a second chamber; a plurality of inlet tubes structured and configured to allow ambient air to enter the first chamber; a plurality of flow tubes structured and configured to allow air to pass from the first chamber to the second chamber; a blower structured and configured to produce a flow of air at positive pressure, wherein the blower is positioned in the first chamber and structured and configured to receive air from the second chamber; an inlet end suspension to support the blower adjacent a blower inlet of the blower; and an outlet end suspension to support the blower adjacent a blower outlet of the blower, wherein the first chamber, the second chamber, the inlet tubes, the flow tubes, and the blower are arranged to form an air flow path extending from an inlet to the blower inlet of the blower and from the blower outlet of the blower to an outlet, wherein the air flow path includes a general U-shape from the inlet to the outlet.

Claims (19)

1. Apparatus for generating a supply of air at positive pressure for the amelioration or treatment of a respiratory disorder, comprising: a first chamber; a second chamber; a plurality of inlet tubes structured and configured to allow ambient air to enter the first chamber; a plurality of flow tubes structured and configured to allow air to pass from the first chamber to the second chamber; a blower structured and configured to produce a flow of air at positive pressure, wherein the blower is positioned in the first chamber and structured and configured to receive air from the second chamber; an inlet end suspension to support the blower adjacent a blower inlet of the blower; and an outlet end suspension to support the blower adjacent a blower outlet of the blower, wherein the first chamber, the second chamber, the inlet tubes, the flow tubes, and the blower are arranged to form an air flow path extending from an inlet to the blower inlet of the blower and from the blower outlet of the blower to an outlet, wherein the air flow path includes a general U-shape from the inlet to the outlet.

14. The apparatus according to any one of claims 1 to 12, further comprising a housing including an upper portion and a lower portion and defining the first and second chambers, wherein the upper and lower portions are engageable or separable in a generally normal direction with respect to an axis of the plurality of inlet tubes and/or an axis of the plurality of flow tubes.
15. The apparatus according to any one of claims 1 to 14, further comprising a flow rate sensor structured and configured to measure a first pressure in the first chamber and a second pressure in the second chamber to determine an air flow rate.
16. The apparatus according to any one of claims 1 to 15, wherein the blower is provided along a leg of the general U-shape.
17. The apparatus according to claim 16, wherein the blower is provided along an outlet leg of the general U-shape extending from the housing outlet.
18. The apparatus according to claim 17, wherein the blower includes an axis that is generally co-linear with an axis of the outlet leg of the general U-shape. JAWS Ref: 506133NZDIV1
19. A system for treating a respiratory disorder, comprising: a patient interface structured and configured to form a seal with a patient’s face; the apparatus according to any one of claims 1 to 18; and an air circuit to connect the patient interface and the apparatus.
