Abstract

A respiratory pressure therapy (RPT) device is disclosed for treatment of respiratory-related disorders. The RPT device includes a pressure generator, a pneumatic block, a chassis and a device outlet for delivering a supply of flow of gas to a patient interface. The RPT device also comprises an integrated humidifier including a water reservoir. An RPT device is also disclosed that includes a wireless data communication interface integrated with the housing and configured to connect to another device or a network.

First claim

1 . An apparatus for use in treating a respiratory disorder, the apparatus comprising:
a housing; a pressure generator within the housing and configured to supply a flow of air; a device outlet fluidly coupled to the pressure generator and configured to be coupled to an air circuit to deliver the flow of air to a patient interface for treating a respiratory disorder; and a wireless data communication interface integrated within the housing, the wireless data communication interface configured to connect to another device or a network.

2 . The apparatus as claimed in claim 1 , wherein the wireless data communication interface is configured to connect to one or more of the Internet and a cellular telephone network.

3 . The apparatus as claimed in claim 1 , wherein the wireless data communication interface uses one or more of CDMA, GSM, LTE, Wi-Fi, Bluetooth, and a consumer infrared protocol.

4 . The apparatus as claimed in claim 1 , the wireless data communication interface comprising an antenna within the housing.

5 . The apparatus as claimed in claim 4 , the wireless data communication interface further comprising an antenna ground plane.

6 . The apparatus as claimed in claim 5 , wherein the antenna ground plane is vertically oriented.

7 . The apparatus as claimed in claim 5 , wherein the antenna ground plane comprises one or more notches.

8 . The apparatus as claimed in claim 7 , wherein the notches increase an effective total length of the ground plane.

9 . The apparatus as claimed in claim 8 , wherein the notches increase the effective total length by more than approximately 25%.

10 . A apparatus for use in treating a respiratory disorder comprising:
a housing; a pressure generator located in the housing and configured to supply a flow of air; a device outlet fluidly coupled to the pressure generator and configured to be coupled to an air circuit to deliver the flow of air to a patient interface for treating a respiratory disorder; and a muffler removably coupled to the housing, wherein said muffler further comprises a muffler body, an inlet for receiving the flow of air from the pressure generator, an outlet for delivering the flow of air to the device outlet, clips for disengaging the muffler from the housing and a muffler damper comprising a flexible material configured to reduce a noise produced by the apparatus during operation, wherein the muffler damper comprises a travel limiter configured to prevent plastic deformation of a hinge connecting the clips to the muffler body.

11 . The apparatus as claimed in claim 10 , wherein the travel limiter is formed integrally with the muffler damper.

12 . The apparatus as claimed in claim 10 , wherein the muffler further comprises a rib, and the muffler damper comprises a recess configured to engage with the rib.

13 . The apparatus as claimed in claim 10 , wherein the muffler body comprises an expansion chamber therein.

14 . The apparatus as claimed in claim 13 , wherein the expansion chamber is at least partly defined by a foam body.

15 . The apparatus as claimed in claim 14 , wherein the foam body is located in the muffler body.

16 . The apparatus as claimed in claim 10 , wherein the housing comprises a dock configured to receive the muffler.

17 . The apparatus as claimed in 16 , further comprising a sensor configured to determine a presence or absence of the muffler in the dock.

18 . The apparatus as claimed in claim 17 , wherein the muffler further comprises an identification element for detection by the sensor.

19 . The apparatus as claimed in claim 18 , wherein the identification element is a magnet.

20 . A apparatus for use in treating a respiratory disorder comprising:
a housing; a pneumatic block comprising an air path therein; a pressure generator located in the pneumatic block and configured to supply a flow of air; a device outlet fluidly coupled to the pressure generator and configured to be coupled to an air circuit to deliver the flow of air to a patient interface for treating a respiratory disorder; and a chassis configured to locate the housing, the pneumatic block and the device outlet, the chassis comprising a dock for receiving a muffler or a humidifier reservoir.
