Patient treatment system with a patient interface mounted control

1. A patient interface assembly for communicating pressurized gas from a gas delivery system to a patient, the patient interface assembly comprising:

a patient interface appliance that is physically separate and discrete from the gas delivery system;

a proximate portion of a patient circuit that delivers pressurized gas from the gas delivery system to the patient interface appliance;

a headgear assembly that is physically separate and discrete from the gas delivery system, the head gear assembly being configured to mount the patient interface appliance on a user; and

a control interface configured to provide a control signal to the gas delivery system that adjusts one or more of a humidifier control, a pressure relief control, a ramp control, or an oxygen concentration level control, the control interface being provided on a leash associated with the headgear assembly and comprising a manually actuatable element provided on an exposed surface, wherein the control signal is provided by the control interface responsive to manual manipulation of the manually actuatable element.

2. The system of claim 1 , wherein the control interface enables the patient to adjust one or more of a humidifier control, a pressure relief control, or a ramp control via a wireless signal.

3. The system of claim 2 , further comprising a wireless transmitter carried by the patient interface assembly that generates a wireless output signal that adjusts one or more of a humidifier control, a pressure relief control, or a ramp control.

4. The system of claim 3 , further comprising a power source carried by the patient interface assembly and supplying power to the transmitter.

5. The system of claim 1 , wherein the patient interface assembly includes a mask, and wherein the control interface is provided on the mask.

6. The system of claim 1 , wherein the patient interface assembly includes a mask and a headgear assembly for mounting the mask on the patient.

7. The system of claim 6 , wherein the control interface is provided on the headgear assembly.

8. The system of claim 6 , wherein a patient circuit communicates the gas delivery system with the mask, and wherein the patient interface assembly includes a proximate portion of the patient circuit.

9. The system of claim 1 , wherein the patient interface assembly includes a proximate portion of a patient circuit that communicates the gas delivery system with the patient interface assembly.

10. The system of claim 1 , further comprising a gas source operatively connected to the gas delivery system in order to supply the breathable gas to the gas delivery system.

11. The system of claim 1 , wherein the gas delivery system incorporates a gas supply.

12. The patient interface assembly of claim 1 , wherein the leash is removably secured to the headgear assembly at one side.

13. The patient interface assembly of claim 1 , wherein the control interface provides the control signal by passively interacting with a non-electronic signal generated remotely from the control interface.

14. The patient interface assembly of claim 13 , wherein the non-electronic signal includes at least one of an optical signal or a pneumatic signal.

15. The patient interface assembly of claim 13 , wherein the non-electronic signal is generated at the gas delivery system.

16. The system of claim 15 , wherein a patient circuit communicates the gas delivery system with the patient interface, and wherein the non-electronic signal is carried to the control interface and/or to the gas delivery system via a signal pathway integrally formed with a patient circuit.

17. The patient interface assembly of claim 1 , wherein the control signal adjusts a control that is also adjustable via an input module disposed on the gas delivery system.

18. The patient treatment system of claim 17 , wherein the at least one aspect of the patient treatment system controlled via the input module and the controls adjustable via the control interface comprise a common aspect that is controllable via both of the input module and the control interface.
