A negative pressure wound therapy system includes a wound dressing, at least one pump fluidly coupled to the fluid interface, a pressure sensor fluidly coupled to the wound dressing, a control housing, and an electrical coupler. The wound dressing includes a sealing layer, an absorbent layer adjacent to the sealing layer, and a fluid interface attached to at least one of the sealing layer or the absorbent layer. The at least one pump is configured to apply negative pressure to the fluid interface to draw fluid from the wound dressing via the fluid interface. The pressure sensor is configured to detect a fluid pressure of the wound dressing. The control housing is remote from the wound dressing. The electrical coupler is configured to removably connect the control housing to the at least one pump.
