摘要： 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.

摘要： A portable negative pressure wound therapy system includes a dressing assembly for positioning over a wound to apply a negative pressure to the wound and a canister assembly. The canister assembly includes a control unit having a vacuum source and a controller and a collection canister in communication with the dressing assembly operable to receive fluid from the wound. The collection canister has a filter assembly having a filter and a passageway between the filter and a wall of the collection canister. The collection canister also includes a canister interface having a suction port, an inlet port, and a channel. The vacuum source draws air through the suction port from the channel which draws air from the passageway connected to the channel, the air in the passageway is drawn from the collection canister through the filter, and the air in the collection canister is drawn through the inlet port.

摘要： 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.

摘要： 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.
