Abstract: A cover for protecting a tissue site may comprise a shell layer, an adhesive disposed on the shell layer, and a contact layer disposed adjacent to the adhesive. The contact layer may have a first pattern of apertures and bridges, and the shell layer may have a second pattern of apertures overlaying the bridges. In some examples, the adhesive may have a bond strength that is greater than the tensile modulus of the shell layer. The contact layer may have an open area of about 40 percent to about 50 percent of the total area of the contact layer. A release liner may be disposed adjacent to the contact layer. Perforations through the shell layer and the contact layer can define a sacrificial segment configured to be separated from the shell layer and the contact layer. A handling bar may be coupled to the sacrificial segment.

Abstract: A wound therapy system includes a canister configured to contain fluid removed from a wound site, a primary conduit having a first end coupled to the canister and a second end coupled to the wound site, and a pump fluidly coupled to the wound site via the primary conduit. The pump is configured to apply negative pressure to the wound site via the primary conduit. The system includes a pressure indicator configured to indicate a negative pressure at the pressure indicator and a secondary conduit having a first end coupled to the pressure indicator and a second end coupled to the wound site such that the negative pressure at the wound site is fluidly transmitted to the pressure indicator via the secondary conduit. A blockage in the primary conduit causes the negative pressure indicated by the pressure indicator to differ from the negative pressure applied by the pump.
