Abstract: An ostomy bag has a non-adhesive filter formed by a carbon fabric disc with impermeable layers on the front and back surfaces. The front layer has a central aperture whereas the rear layer is imperforate. The filter is releasably secured to an adhesive area around a vent opening of the bag with the aperture aligned with the opening so that gas can flow into the filter and radially outwards. The filter be peeled off and reversed to block escape of gas from the opening.

Abstract: A male urine collection device has a short sheath the rear end of which fits over the glans and a short part of the shaft of the penis. The device is of latex rubber and is between 0.6 mm and 1.0 mm thick at its rear end. At its forward end, the device has a outlet tube which is joined to the rear end by a bulbous surge chamber. The rear end of the sheath is everted back over the outlet tube at the mouth of the surge chamber and is self supporting so that, when it is held against the tip of the penis, the rear end can be pushed rearwardly to cause it to revert about the penis. An adhesive band around the rear end of the sheath is protected by a release sheet which can be removed as the sheath reverts about the penis.

Abstract: A valve for a urine collection bag has a base plate with a valve housing within which a valve member is displaceable. The valve member is hollow and has an aperture that aligns with an aperture in the base plate and bag when the valve member is in its lower position. The valve is opened by squeezing a finger plate on the valve member down towards a lower finger grip on the base plate. In the open position, the valve member can engage a coupling which slots between the arms of a fork projection on the base plate. The valve is closed by squeezing the finger plate up towards an upper finger grip on the base plate.

Abstract: A wc disposable ostomy bag has a wall formed from an inner layer of polyethylene and an outer layer of polyvinyl alcohol. Two flexible layers of aluminum are located between the inner and outer layers to reduce odor transmission through the wall. The material of the walls may be formed by vapor depositing the aluminum layers on respective faces of the inner and outer layers and then laminating the inner and outer layers together with the aluminum layers facing one another. Alternatively, both aluminum layers may be deposited on the same one of the inner or outer layers with a thin non-metallic layer between them to prevent the aluminum layers having common grain boundaries.

Abstract: A rig for removably mounting a plurality of fishing rods on the deck of a fishing boat centrally of the aft end thereof, such rig comprising a plurality of rod holders mounted on the outboard end of an upright shaft that is received in a mounting bracket on the deck, each rod holder receiving the butt end of a rod such that the rod extends upwardly and outwardly with respect to the upright shaft, at least one rod being disposed on the starboard side of the boat and one rod being disposed on the port side of the boat. Optionally a third rod holder is provided for positioning a rod above and in alignment with the centerline of the boat and extending upwardly and outwardly above the boat motor.

Abstract: A wc-disposable ostomy bag has an outer water soluble layer of polyvinyl alcohol and an inner relatively insoluble layer of polyvinylidene chloride. A flange of a double-sided pressure-sensitive adhesive ring has one side adhered to the outer layer only, around an opening into the bag so that the edge of the outer layer around the opening is left exposed to material passing through the opening. The other side of the flange in use is secured to the patient's skin around the stoma either directly or via a peristomal wafer.

Abstract: A dilatation catheter has a shaft comprising a tube of braided material encapsulated over a major portion of its length in an outer coating of semi-rigid inelastic material. An outer coating of elastic material extends over a minor portion of the length of the shaft at or near its distal end. An inner coating of elastic material is provided over the entire length of the inside of the tube. The distal end portion of the catheter is thereby inflatable by pressure applied from within the shaft to form a balloon. Radio-opaque markers may be provided at each end of the inflatable portion.

Abstract: A surgical drainage bag has a vent opening in a rear wall of the bag. A first mount is attached to the rear wall of the bag and has an opening registering with the opening in the rear wall. A second mount has a tubular plug which is a press fit in the opening in the first mount and communicates with a recess containing a filter element.
