Reduced pressure therapy apparatus construction and control

A negative pressure therapy apparatus comprising:

• a housing comprising a source of negative pressure configured to be in fluidic communication with a wound dressing, the source of negative pressure configured to apply negative pressure to the wound dressing;
• a controller disposed within the housing and configured to operate the source of negative pressure;
• and
• a transmitter configured to wirelessly communicate with a remote computing device when the housing is within a coverage area so as to enable the remote computing device to determine whether the housing is within the coverage area, the transmitter being configured to function independently from operations or a power supply of the controller.

A method for applying a negative pressure wound therapy to a plurality of wounds, the method comprising, at a first time:

• determining that a negative pressure source is to apply a negative pressure wound therapy via a fluid flow path to a plurality of wounds rather than a single wound;
• activating the negative pressure source to simultaneously provide negative pressure to each of the plurality of wounds;
• determining a first rate of flow in the fluid flow path while the negative pressure wound therapy is applied to the plurality of wounds;
• and
• detecting a first blockage from a comparison of the first rate of flow and a first threshold rather than from a comparison of the first rate of flow and a second threshold different from the first threshold, the first threshold being associated with the negative pressure source applying the negative pressure wound therapy to the plurality of wounds rather than the single wound, the second threshold being associated with the negative pressure source applying the negative pressure wound therapy to the single wound rather than the plurality of wounds.
