    Abstract: The body has a fluid inlet port for receiving pressurized fluid and a fluid outlet port connected to the retention balloon. A first passage connects the fluid inlet port and the fluid outlet port. A second passage in the body is connected to the balloon fluid return path and is at the pressure of the retention balloon. A valve prevents fluid flow through the first passage when actuated. The valve includes a pressure-responsive member movable to a position to obstruct fluid flow in response to fluid pressure in the second passage exceeding the predetermined level. Flexible means such as a membrane defines a normally open portion of the first fluid passage, which is closed by the moveable means bearing on the membrane when pressure exceeding the predetermined level actuates the valve.

    Abstract: An antibacterial wound dressing is based on or derived from gel-forming fibres such as carboxymethyl cellulose or alginate fibres having silver ions linked thereto at some but not all of the exchangeable sites such that the distribution of silver ions over the exchangeable sites is substantially uniform. The silvered fibres for the wound dressing can be prepared by contacting an assembly of precursor gel-forming fibres having exchangeable sites under conditions which do not cause irreversible gelling of the fibres with an amount of a solution containing silver ions so as to link silver ions at some but not all of the exchangeable sites, the whole of the assembly of precursor gel-forming fibres being contacted essentially simultaneously with the entire solution containing silver ions.

    Abstract: A body interface device for a urine aspiration system comprises a skin contact pad with gel adhesive for adhering to the skin, and a flexible cover attached to the pad. The pad includes at least one aperture for admitting urine through the pad into the body interface device. The flexible cover has a bulged form projecting away from the gasket. The flexible cover defines a urine receiving chamber facing towards the gasket, and recess facing away from the chamber for receiving at least a portion of a non-contact liquid sensor. The recess and chamber have a wall portion in common that separates the recess and the chamber. A liquid acquisition material in the chamber receives and transports urine for rapid sensing by the non-contact sensor. An aspiration unit is responsive to the non-contact liquid sensor to apply aspiration suction to the body interface device, upon detection of urine.
