Abstract

A breathing assistance unit for providing pressurized heated humidified air at to a user is configured to increase user compliance. The breathing assistance unit has means for generating positive emotional and cognitive states of a user about the therapy.

Claims

1. A positive airway pressure device configured to improve patient compliance by providing an improved user-friendliness and by reducing cognitive dissonance as a barrier to therapy, the positive airway pressure device comprising

a housing having a substantially square profile and a volume less than 0.008 m³, the housing comprising an outer surface, the outer surface comprising a front wall, a rear wall, a first side wall extending between the front wall and the rear wall and a second side wall extending between the front wall and the rear wall;

a control knob and a control display positioned on the front wall, the control display being positioned directly above the control knob, the control display comprising a clock display;

a humidification compartment having a substantially round profile disposed within the housing, an upper portion of the humidification compartment being covered by a removable lid, the lid being removably attached to the housing and defining a handhold location for carrying of the positive airway pressure device, the humidification compartment being adapted to receive a humidifier chamber, the humidifier chamber being an open top container with a heat-conducting surface and fully enclosed within the humidification compartment except for the open top of the humidification chamber;

an airflow outlet extending from one of the front wall, the first side wall, the second side wall and the rear wall, the airflow outlet being pivotable or rotatable relative to the housing, the airflow outlet being connected to one of the humidification chamber and one of the front wall, the first side wall, the second side wall and the rear wall;

an internal power supply being substantially enclosed within a substantially rectangular cuboid sub-housing disposed in a rear portion within the housing, the sub-housing integrated as part of the rear wall of the housing and including a first sub-housing wall having a first surface area, a second sub-housing wall having a second surface area, and a third sub-housing wall having a third surface area, the internal power supply comprising a power supply component board configured to be connected to a mains voltage source with a power cord; and

a fan unit disposed in a recess beneath the humidification compartment, an inlet to the fan unit being fluidly connected to ambient air and extending through at least one of the front wall, the first side wall, the second side wall, and the rear wall, the fan unit configured to cause air from atmosphere to pass over the first surface area of the first sub-housing wall, the second surface area of the second sub-housing wall, and the third surface area of the third sub-housing wall.

2. The positive airway pressure device of claim 1, wherein the clock display is time-zone adjustable.

3. The positive airway pressure device of claim 1, wherein the humidifier chamber is dishwashable.

4. The positive airway pressure device of claim 1, wherein the humidifier chamber is adapted to hold at least 420 ml of water.

5. A positive airway pressure device configured to improve patient compliance by providing an improved user-friendliness and by reducing cognitive dissonance as a barrier to therapy, the positive airway pressure device comprising

a substantially square-shaped housing comprising an outer surface, the outer surface comprising a front surface;

a control knob and a control display positioned on the front surface, the control display comprising a clock display;

a blower unit, a substantially round-shaped humidification compartment and an internal power supply all disposed within the housing, the internal power supply comprising a power supply component board configured to be connected to a mains voltage source with a power cord, the power supply being substantially enclosed in a sub-housing within the housing, the sub-housing being cuboid and integrated as part of a rear wall of the housing, the sub-housing including a first sub-housing wall having a first surface area, a second sub-housing wall having a second surface area, and a third sub-housing wall having a third surface area, the blower unit disposed in a recess beneath the humidification compartment, the blower unit configured to cause air from atmosphere to pass over the first surface area of the first sub-housing wall, the second surface area of the second sub-housing wall, and the third surface area of the third sub-housing wall; and

wherein any horizontal cross-sectional area of the housing does not exceed 40,000 mm² whereby the housing that contains the blower unit, the humidification compartment and the internal power supply occupies less than 20% of a top of a bedside stand having a width of 480 mm and a depth of 480 mm, the housing having a volume of less than 0.008 m³.

6. The positive airway pressure device of claim 5, wherein the humidification compartment is adapted to receive a humidifier chamber, the humidifier chamber being adapted to hold at least 420 ml of water.

7. The positive airway pressure device of claim 5, wherein an upper portion of the humidification compartment is covered by a removable lid, the lid being removably attached to the housing.

8. The positive airway pressure device of claim 7, wherein the removable lid defines a handhold location for carrying of the positive airway pressure device.

9. The positive airway pressure device of claim 5, wherein the housing further comprises a first side surface and a second side surface each extending rearward from the front surface, a smooth contour being formed by the front surface, the first side surface and the second side surface.

10. The positive airway pressure device of claim 9, wherein an inlet to the blower unit is fluidly connected to ambient air and extends through at least one of the front surface, the first side surface, the second side surface and a rear surface.

11. The positive airway pressure device of claim 10 further comprising an airflow outlet extending from one of the front surface, the first side surface, the second side surface and the rear surface, the airflow outlet being pivotable or rotatable relative to the housing, the airflow outlet being connected to one of the humidification chamber and one of the front surface, the first side surface, the second side surface and the rear surface.

12. The positive airway pressure device of claim 5, wherein the display comprises a smiley face shaped indicator.

13. The positive airway pressure device of claim 5, wherein the control display facilitates playing of sound or music files from a removable memory source.

14. The positive airway pressure device of claim 5, wherein the clock display is time-zone adjustable.

15. The positive airway pressure device of claim 5, wherein the humidification compartment receives a removable humidifier chamber and the removable humidifier chamber is dishwashable.
