Abstract
A wound treatment apparatus is disclosed to provide vacuum therapy to a wound associated with a patient. The wound treatment apparatus comprises a control unit comprising an alarm and a display displaying an alarm log providing information associated with each activation of the alarm. The display also displays information to instruct a user how to operate the wound treatment apparatus. A method of calibrating the control unit is disclosed.
Claims19
A control unit comprising:
- an alarm;
- a vacuum source configured to be coupled to a wound bandage such that the vacuum source is actuatable to communicate negative pressure to the wound bandage;
- a user interface including a display and a plurality of off-screen user-input controls;
- and
- a controller coupled to the alarm, the user interface, and the vacuum source;
- where the controller is programmed for:
- displaying an alarm log screen on the display, the alarm log screen including:
- information associated with prior activations of the alarm;
- first text identifying a first operation performed by an off-screen user-input control when the alarm log screen is displayed;
- and
- a first graphical representation associated with the first operation;
- displaying a second screen on the display, the second screen including:
- second text identifying a second operation performed by an off-screen user-input control when the second screen is displayed, where the second operation includes preventing for a predetermined amount of time negative pressure from being communicated from the vacuum source to a wound bandage;
- and
- a second graphical representation associated with the second operation;
- and
- displaying, responsive to actuation of the user-input control to perform the second operation, a pause screen on the display, the pause screen including:
- third text displaying a predetermined amount of time remaining during which negative pressure is prevented from being communicated from the vacuum source to a wound bandage.

A wound-treatment apparatus comprising:
- a first system including a first vacuum source and configured to be coupled to a first wound bandage such that the first vacuum source is actuatable to communicate negative pressure to the first wound bandage;
- a second system including a second vacuum source and configured to be coupled to a second wound bandage such that the second vacuum source is actuatable to communicate negative pressure to the wound bandage;
- a user interface including a display, a first plurality of off-screen user-input controls, and a second plurality of off-screen user input controls;
- and
- a controller coupled to the user interface, the first system, and the second system;
- where the wound-treatment apparatus is configured such that the first plurality of off-screen user input controls control only the first system, and the second plurality of off-screen user input controls control only the second system;
- and
- where the controller is programmed for:
- displaying a first screen on the display, the first screen including:
- first text identifying a first operation performed by at least one of the first plurality of off-screen user-input controls when the first screen is displayed;
- a first graphical representation associated with the first operation;
- second text identifying a second operation performed by at least one of the second plurality of off-screen user-input controls when the first screen is displayed;
- and
- a second graphical representation associated with the second operation.

A wound-treatment apparatus comprising:
- a vacuum source configured to be coupled to a wound bandage such that the vacuum source is actuatable to communicate negative pressure to the wound bandage;
- an irrigation mechanism configured to be coupled to the wound bandage such that the irrigation mechanism is actuatable to deliver fluid to the wound bandage;
- a user interface including a display, and a plurality of off-screen user-input controls;
- and
- a controller coupled to the user interface, the vacuum source, and the irrigation mechanism;
- where the controller is programmed for:
- displaying a first screen on the display, the first screen including:
- first text identifying a first operation performed by a first one of the plurality of off-screen user-input controls when the first screen is displayed;
- and
- a first graphical representation associated with the first operation;
- displaying a second screen on the display, the second screen including:
- second text identifying a second operation performed by the first one of the plurality of off-screen user-input controls when the second screen is displayed;
- and
- a second graphical representation associated with the second operation;
- where at least one of the first and second screens includes text identifying an irrigation operation performed by one of the plurality of off-screen user-input controls when the at least one of the first and second screens is displayed on the display, and where the irrigation operation includes actuating the irrigation mechanism to deliver fluid when the off-screen user-input control is depressed and to not deliver fluid when the off-screen user-input control is released.
