Wound fluid collection canister with integrated irrigation fluid pump head
View Patent ↗A combined instillation fluid delivery pump head and wound fluid collection canister apparatus for use with a negative pressure wound therapy (NPWT) unit includes a body defining a wound fluid collection canister configured to collect wound exudate and defining a pump head formed by a partially cylindrical recess in a wall of the body. The apparatus includes a flexible fluid instillation conduit extending along the pump head to be compressed by a pump rotor from the NPWT unit. The apparatus includes a first conduit fluidly coupled on one end of the first conduit to a negative pressure source on the NPWT unit. The apparatus includes a second conduit having one end of the second conduit communicating with the wound fluid collection canister. The apparatus includes a third conduit fluidly coupled to one end of the flexible fluid instillation conduit.
1 . An instillation and negative pressure wound therapy apparatus comprising:
an instillation and exudate unit comprising:
a body defining a wound fluid collection canister configured to collect wound exudate and defining a pump head formed by a partially cylindrical recess in a wall of the body;
a flexible fluid instillation conduit extending along the pump head and configured to be compressed by a pump rotor, the flexible fluid instillation conduit having a first end coupled to a first port formed by the wall and a second end coupled to a second port formed by the wall, the first port and the second port on opposing sides of the partially cylindrical recess in the wall;
a first conduit disposed on an interior of the body and configured to be fluidly coupled on one end of the first conduit to a negative pressure source and on another end to a wound site;
a second conduit disposed on the body and having one end of the second conduit communicating with the wound fluid collection canister and on a second end to a wound site; and
a third conduit disposed on the body and fluidly coupled to the flexible fluid instillation conduit through the first port;
a negative pressure wound therapy unit coupled to the instillation and exudate unit,
the negative pressure wound therapy unit further comprising:
a peristaltic pump configured to pump instillation fluid through the third conduit and configured to compress the flexible fluid instillation conduit.
2 . The apparatus of claim 1 , further comprising: a port disposed on the wound fluid collection canister and configured to allow exudate to drain from the wound fluid collection canister.
3 . The apparatus of claim 1 , further comprising: an attachment mechanism configured to couple the instillation and exudate unit to the negative pressure wound therapy unit.
4 . The apparatus of claim 1 , further comprising:
a multi-lumen tube element comprising a first lumen, a second lumen, and a third lumen;
wherein the first lumen is configured to fluidly couple the first conduit to a dressing, the second lumen is configured to fluidly couple the second conduit to the dressing, and the third lumen is configured to couple the third conduit to the dressing.
