Abstract:
1. A therapeutic combination of promoting tissue healing, comprising: a porous pad which is permeable to fluids; a tube having a first end in fluid communication with said porous pad; a canister for collecting fluids drawn through said tube, said canister being fluidly connected with a second end of said tube which is opposite the first end of said tube, wherein said canister is removably received in a recess in a housing; a suction pump for applying negative pressure to said tube, said suction pump being fluidly connected to said canister; at least one bacterial filter between said canister and said suction pump; an elastomeric film dressing having a pressure-sensitive adhesive in peripheral areas for securing said porous pad to tissue within a sealed space; a sensor for detecting when said canister is substantially full with fluid, said sensor being associated with said suction pump to discontinue application of the negative pressure when a substantially full condition of said canister is detected; and a switch providing a signal indicating that the canister properly resides within the recess when the switch is pressed.
