Abstract
A negative pressure wound therapy device can include a negative pressure source and a controller configured to activate the negative pressure source for a first duration of time to attempt to reduce pressure under the wound dressing to approximately ae negative pressure set point, subsequent to expiration of the first duration of time, deactivate the negative pressure source after pressure under the wound dressing is reduced to approximately the negative pressure set point, activate the negative pressure source for a second duration of time to attempt to reduce pressure in the fluid flow path, the second duration of time subsequent to the first duration of time, determine a pressure change in a fluid flow path over the second duration of time, and, in response to determining that the pressure change in the fluid flow path over the second duration of time indicates reduction in pressure, provide indication of a blockage.
