Reduced pressure therapy apparatuses and methods of using same

A negative pressure wound therapy device comprising:

• a housing;
• a pressure source positioned at least partially within the housing and configured to be in fluid communication, via a fluid flow path, with a wound covered by a wound dressing;
• a user input interface positioned at least partially on an exterior surface of the housing, the user input interface configured to receive one or more inputs from a user;
• and
• a controller supported by the housing and configured to receive one or more indications from the user input interface associated with the one or more user inputs, the controller further configured to:
• transition from an inactive state to an active state in response to receiving a first indication from the user input interface;
• monitor a duration of time of operating in the active state;
• when in the active state, activate the pressure source to cause provision of negative pressure to the wound via the flow path in response to receiving a second indication from the user input interface;
• and
• in response to the duration of time of operating in the active state reaching a lifetime threshold, transition to an end of life state in which generation of negative pressure by the pressure source is disabled.

A negative pressure wound therapy device comprising:

• a housing;
• a pressure source positioned at least partially within the housing and configured to be in fluid communication with a wound covered by a wound dressing;
• a user input interface positioned at least partially on an exterior surface of the housing, the user input interface configured to receive one or more inputs from a user;
• and
• a controller supported by the housing and configured to receive one or more indications from the user input interface, the one or more indications associated with the one or more user inputs, the controller further configured to:
• in response to receiving at least one indication from the user input interface to provide negative pressure wound therapy:
• monitor a duration of time associated with providing negative pressure wound therapy;
• and
• activate the pressure source to cause provision of negative pressure to the wound via a fluid flow path fluidically connecting the pressure source to the wound;
• and
• in response to the duration of time associated with providing negative pressure wound therapy reaching a lifetime threshold, disable generation of negative pressure by the pressure source.

A negative pressure wound therapy device comprising:

• a housing;
• a pressure source positioned within the housing and configured to be in fluid communication, via a fluid flow path, with a wound covered by a wound dressing;
• a user input interface positioned on an exterior surface of the housing, the user input interface consisting of a single button configured to be pressed by a user;
• a controller supported by the housing and configured to receive an input from the user when the button is pressed, the controller further configured to:
• activate the pressure source upon a first pressing of the button;
• deactivate the pressure source upon a second pressing of the button subsequent to the first pressing of the button;
• and
• re-activate the pressure source upon a third pressing of the button subsequent to the second pressing of the button;
• and
• at least three indicators positioned at least partially on the exterior surface of the housing, the at least three indicators comprising:
• a first indicator configured to indicate that the pressure source has been activated;
• a second indicator configured to indicate a leak condition;
• and
• a third indicator configured to indicate a remaining capacity of a power source.
