Reduced pressure therapy apparatuses and methods of using same

A method of operating a negative pressure wound therapy device, the method comprising:

• by an electronic control circuitry of the negative pressure wound therapy device:
• distinguishing between a first leak in a fluid flow path associated with a first fluid flow rate and a second leak in the fluid flow path associated with a second fluid flow rate that exceeds the first fluid flow rate, the fluid flow path connecting a negative pressure source of the negative pressure wound therapy device to a wound dressing that covers a wound, the negative pressure source configured to provide negative pressure to the wound via the fluid flow path;
• at a first time, responsive to presence in the fluid flow path of the first leak associated with the first fluid flow rate, causing the negative pressure source to continue to provide negative pressure to the wound;
• at a second time, responsive to presence in the fluid flow path of the second leak associated with the second fluid flow rate:
• providing a first indication that the second leak is present;
• and
• responsive to expiration of a first duration of time, deactivating the negative pressure source thereby stopping provision of therapy to the wound;
• monitoring a second duration of time following an initial activation of the negative pressure wound therapy device;
• and
• at a third time, responsive to determining that the second duration of time has reached a lifetime threshold, permanently disabling activation of the negative pressure source, wherein the second duration of time comprises time during which the negative pressure source is ON and OFF.
