Abstract: Systems, methods, and apparatuses for forming a multi-function core for a dressing are described. The multi-function core includes a contact layer configured to be positioned adjacent to a tissue site, a wicking layer adjacent to the contact layer, an ion exchange layer adjacent to the wicking layer, an absorbing layer adjacent to the ion exchange layer, a blocking layer adjacent to the absorbing layer, and an odor-absorbing layer adjacent to the blocking layer. The contact layer, the wicking layer, the ion exchange layer, the absorbing layer, the blocking layer, and the odor-absorbing layer are coextensive and formed from a plurality of fibers disposed in a fibrous web. Methods of manufacturing the multi-function core are also described.

Abstract: Systems, methods, and apparatuses for treating a tissue site with reduced pressure are described. The system includes a manifold configured to be placed adjacent the tissue site, and a sealing member configured to be placed over the tissue site and the manifold. The system also includes a reduced-pressure source fluidly coupled to the manifold through the sealing member. The system further includes a pouch having an upstream layer having a first thickness, a downstream layer having a second thickness, and an absorbent member enclosed between the upstream layer and the downstream layer. The second thickness is greater than the first thickness. The upstream layer may have a hydrophilic side adjacent the absorbent member, and the downstream layer may have a hydrophobic side adjacent the absorbent member.

Abstract: Illustrative embodiments of new and useful systems and methods for reduced-pressure therapy are described. One example embodiment is a manually-actuated pump for applying reduced-pressure therapy. The pump generally comprises a charging chamber, a regulated chamber, and a regulator passage between the charging chamber and the regulated chamber. A valve body controls fluid communication through the regulator passage, and a regulator spring may be engaged with the valve body to bias the valve body against a differential between a pressure in the regulated chamber and an ambient pressure. The regulator passage may have a bore size adapted deflect the valve body to cause an audible indication of a leak.

Abstract: In some illustrative embodiments, a system suitable for treating a tissue site may include a dressing, a low-profile conduit, a conduit interface, and a reduced-pressure source. The dressing may be adapted for positioning at the tissue site. The low-profile conduit may be adapted for fluidly coupling to the dressing. The low-profile conduit may include a manifold and a sealing member encapsulating the manifold. The conduit interface may be adapted for fluidly coupling to the low-profile conduit. The conduit interface may be in fluid communication with the dressing through the low-profile conduit. The reduced-pressure source may be adapted for fluid communication with the conduit interface. Other systems, devices, and methods are disclosed.

Abstract: Pump cassettes, wound-treatment apparatuses and methods. In some embodiments, a pump cassette comprises: a pump body having a pump chamber, an inlet valve in fluid communication with the pump chamber, and an outlet valve in fluid communication with the pump chamber; a diaphragm coupled to the pump body such that the diaphragm is movable to vary a volume in the pump chamber; and an identifier configured to store one or more properties of the pump cassette such that the identifier is readable by an automated reader to determine the one or more properties. In some embodiments, the pump cassette is configured to be removably coupled to a wound-treatment apparatus having an actuator such that the actuator can be activated to move the diaphragm.

Abstract: A dressing for treating a tissue site with negative pressure includes a manifold having a first surface and a second surface opposite the first surface. The dressing also includes a first layer adjacent to the first surface and a second layer adjacent to the second surface. The first layer and the second layer each include a polymer film. The dressing also includes a plurality of fluid restrictions in the polymer film adjacent to at least the first surface, and a plurality of bonds between the first layer and the second layer. The plurality of bonds defines separable sections of the manifold.
