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. ## Claims ### Claim 1 An apparatus for providing reduced-pressure to a tissue site through a primary lumen, the apparatus comprising: a reduced-pressure source; and a controller configured to: operate the reduced-pressure source to change pressure in the primary lumen; measure pressure through a first measurement lumen and a second measurement lumen, each of the first measurement lumen and the second measurement lumen having openings near the tissue site; monitor a response time of pressure measured through the first measurement lumen and the second measurement lumen to the pressure change in the primary lumen; and open one or more of the first measurement lumen and the second measurement lumen to a pressure greater than the pressure in the primary lumen if the response time indicates a delayed response. ### Claim 2 (depends on 1) The apparatus of claim 1, further comprising: an adapter coupled to primary lumen, the first measurement lumen, and the second measurement lumen, the adapter comprising channels configured to direct liquid away from the first measurement lumen and the second measurement lumen. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the adapter comprises: a housing having an entry surface; a primary conduit through the housing coupled to the primary lumen and terminating on the entry surface; a first ancillary conduit through the housing coupled to the first measurement lumen and terminating on the entry surface; and a second ancillary conduit through the housing coupled to the second measurement lumen and terminating on the entry surface. ### Claim 4 (depends on 3) The apparatus of claim 3, further comprising: a base attached to the housing; and guide channels on the base. ### Claim 5 (depends on 3) The apparatus of claim 3, further comprising: a base attached to the housing; and radial guide channels on the base adapted to direct liquid from a periphery of the base away from the first ancillary conduit and the second ancillary conduit. ### Claim 6 (depends on 3) The apparatus of claim 3, further comprising a base attached to the housing, wherein the housing is rotatable about the base.
