摘要： A device is provided for deliberately distributing simultaneously over the entire vertical and/or longitudinal extend of a body of aqueous containing liquid a gelation agent for the rapid containment of contaminated aqueous liquids. The device is an elongated rigid or semi-rigid body for containing an envelope or package of material immediately dissolvable in the aqueous liquids, and which contains the gelling agent prior to liquid exposure. The device includes means for exposure of its content to the liquid, once the device is positioned in or is surrounded by the liquid. The invention contemplates a conventional suction canister having the device positioned therein for receiving contaminated body fluids.

摘要： A polyurethane composition has particles of solid polyvinylpyrrolidone-iodine complex evenly distributed throughout the polyurethane matrix so that the complex does not associate with the polyurethane to any appreciable extent. In one embodiment of the composition, the polyurethane is thermoplastic for coating or molding applications. In another embodiment, the composition is a polyurethane foam particularly useful as a sponge for scrubbing which provides almost instantaneous release of the complex. The sponge may be provided in a package which includes other items useful for scrubbing.
