1. An apparatus for applying negative pressure wound therapy, the apparatus comprising:
a source of negative pressure configured to supply, via a fluid flow path, negative pressure to a wound covered by a wound dressing;
a user interface configured to receive input from a user and provide operational status to the user;
a controller; and
a memory storing instructions that, when executed by the controller, cause the controller to:
become active responsive to detection of an activation event;
responsive to a first user input received via the user interface while the controller is active, activate the source of negative pressure to supply negative pressure to the wound; and
become inactive responsive to determining that a lifetime threshold has been reached.
