Claim 14:
15. A method of operating a negative pressure wound therapy apparatus, the method comprising:
receiving an activation input with a user interface;
at a first time, determining that a first sensor detects that a wound dressing is positioned over a wound;
in response to receiving the activation input and determining that the first sensor detects that the wound dressing is positioned over the wound, supplying negative pressure with a negative pressure source to the wound via a fluid flow path connecting the negative pressure source to the wound dressing;
at a second time, determining that the first sensor does not detect that the wound dressing is positioned over a wound; and
in response to determining that the first sensor does not detect that the wound dressing is positioned over the wound, preventing supply of negative pressure with the negative pressure source to the wound,
wherein the method is performed under control of a control circuitry of the negative pressure wound therapy apparatus.
