Pressure wound therapy status indication via external device

A negative pressure wound therapy system comprising:

• a negative pressure therapy apparatus configured to apply negative pressure to a wound of a patient, the negative pressure therapy apparatus comprising:
• a wound dressing configured to be placed over the wound,
• a negative pressure source embedded in the wound dressing and configured to apply negative pressure to the wound, and
• a first controller configured to determine operating data of the negative pressure therapy apparatus;
• a first wireless communication device configured to be communicatively coupled to the negative pressure therapy apparatus, the first wireless communication device comprising:
• a first display,
• a second controller configured to receive the operating data from the negative pressure therapy apparatus and output an indication of at least some of the operating data on the first display, and
• a first wearable housing configured to support the first display and the second controller of the first wireless communication device, wherein the first wearable housing is configured to be worn by the patient or a caregiver of the patient;
• a second wireless communication device configured to be communicatively coupled to the negative pressure therapy apparatus, the second wireless communication device comprising:
• a second display,
• a third controller configured to receive the operating data from the negative pressure therapy apparatus and output an indication of at least some of the operating data on the second display, and
• a second wearable housing configured to support the second display and the third controller of the second wireless communication device, wherein the second wearable housing is configured to be worn by the patient or the caregiver of the patient,
• wherein the second controller of the first wireless communication device is configured to handover communication with the negative pressure therapy apparatus to the third controller of the second wireless communication device,
• wherein the handover causes the operating data to be received by the third controller of the second wireless communication device but not by the second controller of the first wireless communication device;
• wherein the first wireless communication device and the second wireless communication device are configured to transmit a user input to the first controller, and the first controller is configured to receive the user input from at least one of the first wireless communication device and the second wireless communication device;
• and
• wherein the negative pressure therapy apparatus is further configured to transmit the operating data to one or both of the first and second wireless communication devices responsive to an expiration of a time interval.
