Abstract
A system for applying reduced pressure to tissue includes a multi-lumen reduced pressure delivery tube having a proximate end, a distal end, a primary lumen extending through the conduit from the proximate end to the distal end, and an ancillary lumen extending through the conduit from the proximate end to the distal end. A vacuum pump is coupled to the proximate end of the primary lumen, and a reduced pressure adapter is coupled to the distal end of the reduced pressure delivery tube. The adapter includes channels to direct liquid away from the ancillary lumens and into the primary lumen.
Claims20
An adapter for reduced-pressure treatment, the adapter comprising:
- a base;
- a perimeter ring attached to the base;
- a first bearing ring within the perimeter ring;
- a sealing ring within the first bearing ring;
- a second bearing ring within the sealing ring;
- and
- a housing coupled to the perimeter ring and rotatable around the second bearing ring.
A multi-lumen reduced-pressure delivery apparatus having a first end and a second end, comprising:
- a primary conduit extending from the first end to the second end;
- and
- an ancillary conduit extending from the first end to the second end adjacent to the primary conduit;
- wherein the primary conduit has a first cross-section and the ancillary conduit has a second cross-section substantially smaller than the first cross-section.
A system for providing reduced pressure to a tissue site, the system comprising:
- a delivery lumen fluidly coupled to the tissue site;
- a reduced-pressure source fluidly coupled to the delivery lumen;
- a first measurement lumen fluidly coupled to the tissue site;
- a first pressure sensor fluidly coupled to the first measurement lumen;
- a first valve fluidly coupled to the first measurement lumen;
- a second measurement lumen fluidly coupled to the tissue site;
- a second pressure sensor fluidly coupled to the second measurement lumen;
- a second valve fluidly coupled to the second measurement lumen;
- and
- a controller coupled to the reduced-pressure source, the first pressure sensor, the first valve, the second pressure sensor, and the second valve, the controller configured to:
- receive data from the first pressure sensor and the second pressure sensor indicative of pressure at the tissue site,
- compare data from the first pressure sensor and the second pressure sensor,
- open the first valve if a response time of the first pressure sensor is greater than a response time of the second pressure sensor, and
- operate the reduced-pressure source based on the data from the second pressure sensor if the response time of the first pressure sensor is greater than the response time of the second pressure sensor.
