Abstract

Apparatus for generating a supply of air at positive pressure for the amelioration or treatment of a respiratory disorder, comprising: at least one chamber; a blower structured and configured to produce a flow of air at positive pressure, wherein the blower is located downstream of the at least one chamber; and a plate assembly including a base plate that defines a wall of the at least one chamber, at least one tube structured and configured to allow air to enter the at least one chamber, and a blower suspension to support the blower, wherein the blower suspension includes a gusset portion structured and configured to allow flexibility and relative movement to isolate vibrations of the blower and provide shock resistance, and wherein the plate assembly comprises an integral unit in which the blower suspension comprises an overmolded connection to the base plate.

Claims (13)

1. Apparatus for generating a supply of air at positive pressure for the amelioration or treatment of a respiratory disorder, comprising: at least one chamber; a blower structured and configured to produce a flow of air at positive pressure, wherein the blower is located downstream of the at least one chamber; and a plate assembly including a base plate that defines a wall of the at least one chamber, at least one tube structured and configured to allow air to enter the at least one chamber, and a blower suspension to support the blower, wherein the blower suspension includes a gusset portion structured and configured to allow flexibility and relative movement to isolate vibrations of the blower and provide shock resistance, and wherein the plate assembly comprises an integral unit in which the blower suspension comprises an overmolded connection to the base plate.
2. Apparatus according to claim 1, wherein the plate assembly is a first plate assembly and the apparatus further comprises a second plate assembly, wherein the at least one tube of the first plate assembly is an inlet tube that allows air to enter the at least one chamber and the second plate assembly includes at least one flow tube that allows air to exit the at least one chamber.
3. Apparatus according to any one of claims 1 or 2, wherein the plate assembly is a first plate assembly and the apparatus further comprises a second plate assembly, wherein the blower suspension of the first plate assembly is an outlet end suspension to support the blower adjacent a blower outlet of the blower and the second plate assembly includes an inlet end suspension to support the blower adjacent a blower inlet of the blower. JAWS Ref: 506133NZDIV5
4. Apparatus according to any one of claims 2 or 3, wherein the second plate assembly includes a base plate that defines a wall of the at least one chamber.
5. Apparatus according to claim 4, wherein the at least one chamber includes a first chamber and a second chamber, and wherein the base plate of the first plate assembly defines a wall of the first chamber and the base plate of the second plate assembly defines a wall of the first and second chambers.
6. Apparatus according to any one of claims 1 to 5, further comprising a sealing lip along a perimeter of the base plate configured to provide a seal along an edge of the at least one chamber.
7. Apparatus according to claim 6, wherein the sealing lip comprises an overmolded connection to the base plate.
8. Apparatus according to any one of claims 1 to 7, wherein the plate assembly further comprises a pressure port structured and configured to interface or otherwise connect to a pressure sensor.
9. Apparatus according to claim 8, wherein the pressure port comprises an overmolded connection to the base plate.
10. Apparatus according to any one of claims 1 to 9, wherein the plate assembly further comprises an outlet bellows structured and configured to form a seal with an end of an air circuit.
11. Apparatus according to claim 10, wherein the outlet bellows comprises an overmolded connection to the base plate. JAWS Ref: 506133NZDIV5
12. Apparatus according to any one of claims 1 to 11, wherein the base plate of comprises a first part constructed of a relatively rigid material and the blower suspension comprises a second part constructed of a relatively soft material overmolded to the first part.
13. 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 12; and an air circuit to connect the patient interface and the apparatus.
