ABSTRACT:
A portable wound treatment apparatus, for stimulating the healing of superficial wounds, comprises a housing containing a suction pump and a canister for containing fluids drawn from the wound. The housing is supported on a harness or belt worn by the patient. The canister is connected to a porous wound dressing at the wound site via a plurality of tubes, a multi-lumen tube or a combination thereof. A rechargeable battery pack may be incorporated within the housing or provided externally thereto. In the case of an external battery pack, the pack may be shaped to balance the housing on the harness or belt. In operation, pressure transducers are provided to monitor and, if desired, report pressures at the wound site or internal to the canister. Monitored pressures may also be utilized to determine the filled state of the canister and, thereafter, either report this state to the operator or automatically discontinue suction from the wound, or both.
