Conduit Device For Negative Pressure Wound Therapy System

A conduit device for use with a negative pressure wound therapy system, the conduit device comprising:

• a tubular structure configured to fluidly connect to each of a therapy device and a wound dressing located at a wound site, the tubular structure extending along a longitudinal axis and a lateral axis orthogonal to the longitudinal axis, the tubular structure defining a first end and a second end opposite the first end, wherein the second end is disposed proximal to the wound dressing, the tubular structure comprising:
• a first film that is fluid impermeable;
• a second film connected to the first film, wherein the second film comprising a wound port disposed proximal to the second end of the tubular structure and fluidly communicating with the wound dressing, wherein the first film and the second film together form an interior of the tubular structure, and wherein the second film is fluid impermeable;
• a third film at least partially disposed between and connected to each of the first film and the second film, wherein the third film extends along the longitudinal axis and separates the interior into a first chamber fluidly communicating with the therapy device and a second chamber, wherein the third film is fluid impermeable and fluidly separates the first chamber from the second chamber, and wherein the wound port fluidly communicates the second chamber with the wound dressing;
• a plurality of filters spaced apart from each other along the longitudinal axis, wherein each of the plurality of filters is connected to the third film and is configured to pneumatically communicate the first chamber with the second chamber, and wherein each of the plurality of filters is offset from the wound port with respect to at least one of the longitudinal axis and the lateral axis;
• and
• an absorbent disposed in the first chamber or the second chamber and offset from the wound port with respect to at least one of the longitudinal axis and the lateral axis.
