Portable wound therapy system
First Claim
1. A portable subatmospheric pressure wound therapy system comprising:
- a wound dressing configured to be positioned over a wound;
a subatmospheric pressure source configured to be in fluid communication with the wound dressing and further configured to supply subatmospheric pressure to the wound dressing; and
a plurality of channels configured to be disposed between the wound dressing and the subatmospheric pressure source, the plurality of channels including an inlet port configured to receive exudate removed from the wound and an outlet port configured to be in fluidic communication with the subatmospheric pressure source, wherein the plurality of channels are arranged in a general parallel relation along a major portion of the respective lengths of the channels, the plurality of channels being in fluid communication with each other,wherein at least one of the plurality of channels comprises an absorbent material, andwherein the plurality of channels are made of a flexible material configured to enclose the absorbent material.

Abstract
A portable system for subatmospheric pressure therapy in connection with healing a surgical wound, includes a wound dressing dimensioned for positioning relative to a wound bed of a subject, a portable subatmospheric pressure mechanism dimensioned to be carried or worn by the subject and a container for collecting exudates from the wound bed removed under the subatmospheric pressure supplied by the subatmospheric pressure mechanism. The portable subatmospheric pressure mechanism includes a housing, a subatmospheric pressure source disposed within the housing and in fluid communication with the wound dressing to supply subatmospheric pressure to the wound dressing and a power source mounted to or within the housing for supplying power to actuate the subatmospheric pressure source.
