Abstract: An external catheter, and the methods of making and using such a catheter, for a male urinary incontinence collection system, such system also including an adhesive attachment for holding the catheter in place. The catheter takes the form of a tubular sheath of thin elastic material having a cylindrical body section, a tapered neck section extending from the body section, and a reduced drainage tube section projecting from the neck section. Within the sheath, and constituting a unitary part thereof, is a tubular inner sleeve of soft elastic material having a distal end portion disposed within the neck section and a proximal end portion merging with the sheath's cylindrical body section. The sleeve tapers distally to define an annular space thereabout, and terminates in a reduced distal opening located at an intermediate point within the neck section.

Abstract: A coupling for an ostomy appliance that detachably joins an ostomy bag to a faceplate capable of being adhesively secured to a patient's skin about a stoma opening. Each coupling ring is formed of flexible and resilient thermoplastic material, with one of the rings having an axially-extending frusto-conical neck portion and the other ring having a frusto-conical collar portion detachably receiving and sealingly engaging the neck portion. Primary latching is achieved in an annular zone spaced a substantial distance radially outwardly from the area of sealing engagement between the neck and collar portions, such latching action being provided by a shoulder extending about the outer periphery of one of the rings and a latching rib, defining a shoulder-receiving recess, extending about the outer periphery of the other ring.

Abstract: A device and method for use in forming an access port, and also in forming a leakproof seal between a conduit (e.g., a catheter tube) and a thermoplastic film (e.g., the wall of an ostomy bag, wound cover pouch, or similar pouch). The device includes internal and external coupling rings adapted to be locked together with a collar of film material clamped therebetween. An elastomeric nipple has an enlarged proximal end portion similarly clamped between the coupling rings and contributes in forming fluid-tight seal between the parts. The method of use of the device is also disclosed, such method including the insertion of a piercing element into the opening of the internal ring to form a two-piece piercing assembly, followed by the step of utilizing that assembly to pierce a flexible plastic film and form a collar of plastic material about the outer surface of the internal ring.

Abstract: An expandable plastic collection bag adapted to be strapped to the leg of an incontinent patient and provided with an inlet tube for directing urine into the bag. The bag also has a clamp-equipped discharge tube to facilitate periodic draining of the bag's contents. The straps are located to exert a force urging the inner wall of the bag into conforming engagement with a wearer's leg, and side pleats allow expansion of the bag in a way that permits a relatively large portion of the inner wall to remain in surface contact with the leg. The inlet and outlet tubes are hingedly mounted for self-adjusting limited pivotal movement towards and away from the bag's outer wall to reduce possibilities that the flow passages might become kinked as the bag is filled. Such pivotal movement is facilitated by openings and by heat seal lines formed in the walls of the bag at the locations of the inlet and outlet tubes.

Abstract: A foam generating unit is adjustably mounted for longitudinal movement on a liquid sprayer having an orifice which provides a diverging liquid stream directed into the inlet of the foam generating unit. The foam generating unit includes a foam-generating section most advantageously having a pressure-reducing inlet passageway section including a preferably sharply outwardly tapering portion leading to a throat portion. Air inlet ports are provided communicating with the pressure-reducing passageway, through which ports air is drawn by the reduced pressure caused by the pressure-reducing passageway. The desired foaming action is achieved by adjusting the points of the pressure-reducing passageway section struck by the stream by moving the foam generating unit relative to the orifice.

Abstract: A sealing closure assembly for a container mouth including a closure cap and a sealing member having a sealing portion which sealingly engages with a releasable locking fit with the mouth of said container and a cap engaging portion slidably engageable by an axially outwardly facing shoulder of the closure cap. The sealing portion of said sealing member remains in place in sealing relation to the closure mouth for a portion of the rotation of said closure cap means when the same is rotated in a direction to unthread the same from the external screw thread means of the container and is forced from sealing and locking engagement with the container mouth by the shoulder of the closure cap solely by the force created by the further unthreading of the closure cap means from said external screw thread means of the closure cap means.

Abstract: A foam generating nozzle is made either as an attachment to an existing liquid spray nozzle unit or as a pre-manufactured assembly and includes a foam-generating section having a pressure-reducing passageway including a preferably sharply outwardly tapering portion leading to a venturi-forming throat portion, and adapted to receive the liquid stream issuing from an inlet orifice. Air inlet ports are provided communicating with the pressure-reducing passageway, through which ports air is drawn by the reduced pressure caused by the pressure-reducing passageway. Optimum foaming action is achieved by adjusting the point of the pressure-reducing passageway struck by the stream which is most advantageously achieved by adjusting the angle of the stream issuing from the orifice so the widest portion thereof strikes the end section of the tapering portion of the passageway.
