A reduced pressure treatment system includes a liquid-collection canister for collecting liquid from a tissue site to which reduced pressure treatment is applied. The canister includes a first space configured to collect the liquid from the tissue site and a filter having a frame and a non-planar filter element. The filter defines a second space within the canister separated from the first space by the filter element. The filter element substantially prevents liquid from passing from the first space into the second space. The filter element substantially allows gaseous communication between the first space and the second space when the second space is exposed to a reduced pressure.

A system and method for measuring the pressure provided by a disc pump is disclosed. The disc pump comprises an actuator mounted within the disc pump on a flexible skirt that allows the actuator to oscillate for generating air flow through the cavity of the pump and allows the actuator to be displaced with increasing pressure to a load. The actuator moves from a rest position when air begins flowing through the cavity to a biased position when the load is fully pressurized or depressurized depending on the direction of fluid flow through the cavity. The pump further comprises a sensor which measures the displacement of the actuator at any position between the rest position and the biased position as fluid begins flowing through the cavity to pressurize or depressurize the load. The pressure being delivered by the disc pump is determined as a function of the displacement of the actuator.

A hanging apparatus is provided that facilitates the attachment of a medical instrument to a support structure. The mechanism includes a generally longitudinal, telescoping assembly that extends outward from the back of the medical instrument and positions a rotatable arm to serve as one face of a clamp, opposing the back of the medical instrument as the second face of the clamp. The mechanism assembly includes a cylindrical shaft that extends outward against the tension force of a spring from a housing component of the assembly. A cam mechanism within the hanging apparatus allows for locking and tightening of the clamp against the support structure after closure of the clamp under the influence of the tensioning spring.

Systems and methods for a reduced-pressure interface for connecting a multi-lumen conduit to a distribution manifold. The interface includes a housing having a flange portion and a cavity wall portion. The cavity wall portion forms a cavity having a tissue-facing cavity opening. The interface further includes an attachment device, a conduit port, and a multi-lumen conduit. The attachment device is coupled to a tissue-facing side of the flange portion for coupling the housing to a sealing member. The conduit includes a distal end and a proximal whereby the distal end extends through a conduit aperture and past the cavity wall portion into the cavity. The conduit further includes a primary lumen and a plurality of sensing lumens. The primary lumen and the plurality of sensing lumens extend from the proximal end of the conduit to the distal end. The conduit is adapted to contact the distribution manifold.

Systems, devices, and methods for treating a tissue site on a patient with reduced pressure are presented. In one instance, a reduced-pressure interface includes a conduit housing having a cavity divided by a dividing wall into a reduced-pressure-application region and a pressure-detection region. The reduced-pressure interface further includes a reduced-pressure port disposed within the reduced-pressure-application region, a pressure-detection port disposed within the pressure-detection region, and a base connected to the conduit housing, the base having a manifold-contacting surface. The dividing wall includes a surface substantially coplanar with the manifold-contacting surface.

A disc pump valve includes an elliptical pump base having at least one aperture extending through the base. The base comprises a first end wall and a sealing surface. The pump includes an isolator overlying the base and having an isolator valve aperture extending through the isolator at or near the periphery of the isolator and partially overlying a cavity formed by the base to form an outlet. In addition, the disc pump includes a valve flap disposed between the pump base and the isolator. The flap has apertures arranged about its periphery, beyond the periphery of the cavity but underlying an isolator valve aperture. The flap seals against the sealing surface to close the pump outlet and prevent fluid from flowing from the outlet into the cavity and flexes away from the sealing surface to allow fluid to pass from the cavity through the pump outlet.
