A wound therapy device is disclosed. The wound therapy device may include a housing for covering at least a portion of a wound and for sealing to a body surface of a patient. The housing may also include a liquid collector for retaining liquid therein and a vacuum connection for coupling to a vacuum source. The vacuum connection may be in gaseous communication with the liquid collector. The vacuum connection may be separated from the liquid collector by a liquid barrier.

A wound fluid collection system includes a canister with a chamber fluidly connected to a wound dressing in a tissue site through an inlet and also fluidly connected to a reduced pressure source through an outlet. At least a portion of the canister is collapsible and yet can be maintained in an extended state when exposed to subatmospheric pressure. The canister is releasably attachable to a supporting member.

A method and apparatus are disclosed for dressing a wound. The apparatus comprises a sealing layer comprising at least one orifice, an absorbent layer over the sealing layer, absorbing wound exude and a liquid impermeable, gas permeable filter layer over the absorbent layer.

Systems, methods, and apparatuses for generating and releasing iodine are described. Some embodiments may include a dressing member including a plurality of iodine-forming reagents and a water-swellable material. In some embodiments, the dressing member may include water-swellable fibers. The water-swellable fibers may each include a water-swellable material in which iodine-forming reagents are dispersed. As liquid comes into contact with and is absorbed by the water-swellable material, the iodine-forming reagents may come into contact with each other, causing an iodine-forming reaction to occur, producing iodine.

A filter adaptor includes a body that defines an internal passageway disposed between an inlet and an outlet, the passageway configured to permit passage of a fluid in a first direction defined by the inlet and the outlet; and a filter disposed within the passageway and oriented to define a volumetric direction that is different than the first direction. Another filter adaptor includes a body that defines an internal passageway disposed between an inlet and an outlet, and a filter disposed within the passageway, wherein the filter comprises a gelling absorbent material that, when in a dry state, is permeable to gas and that, when contacted by an aqueous fluid, converts to a gel. Such filter adaptors may be used for negative pressure wound therapy, dressing, or as syringe filters.

A wound therapy device is disclosed. The wound therapy device may include a housing for covering at least a portion of a wound and for sealing to a body surface of a patient. The housing may also include a liquid collector for retaining liquid therein and a vacuum connection for coupling to a vacuum source. The vacuum connection may be in gaseous communication with the liquid collector. The vacuum connection may be separated from the liquid collector by a liquid barrier.

A surgical drain tray assembly includes a fluid impermeable first layer and a porous second layer positioned on the fluid impermeable first layer. The fluid impermeable first layer includes a drain outlet, a basin, and a sloping surface angled toward the basin, the drain outlet being positioned within the basin. The porous second layer may be formed of a foam material and includes a top work surface. Fluids spilled onto the work surface pass through the porous second layer to the fluid impermeable first layer. The sloping surface of the fluid impermeable first layer conveys the fluids toward the basin for draining through the drainage outlet.
