  • Patent number: 4995868
    Abstract: A catheter, for example for bladder drainage, formed of two coaxial tubes and including near the distal end of the outer tube an expandable and contractable retention structure, for example Malecot wings, and at the proximal end of the inner tube a hollow connector for attachement to a fluid supply or drain, comprises actuating means to effect relative sliding movement of the proximal ends of the tubes so as to expand or contract the retention structure, and which means further include a housing secured to the proximal end of the outer tube and so dimensioned that when the retention structure is moved into the contracted position the hollow connector is withdrawn into the housing. This configuration of actuating means prevents both inadvertent connection of a fluid supply or drain when the retention structure is in the contracted position and attempted removal of the catheter when the retention structure is in the expanded position.

  • Patent number: 4850984
    Abstract: A one-piece connector has a stepped bore, a first end to accommodate an outlet pipe of an outlet tap of a urine drainage leg bag, and a second end to accomodate a nozzle on an inlet pipe of an overnight drainage bag.The second end includes a hand-grippable tab with an enlarged free end.The connector is removed from the nozzle by pulling the tab in a direction towards the leg bag. This pulling action on the tab reduces substantially the tension needed to separate the connector from the nozzle.

  • Patent number: 4840187
    Abstract: A sheath applicator assembly includes a tubular applicator casing, and a netting liner casing located in the applicator casing and secured to a closed end of the casing. A penile sheath is located inside the liner casing. The open end region of the casing is folded back over the casing, and the open end region of the sheath is folded back over the open end region of the casing.

  • Patent number: 4801292
    Abstract: A medical pump comprising an intake/discharge nozzle, a fluid circulator, an elongate barrel extending between and joining the nozzle and circulator, a flushing path and an efflux path peripherally about the flushing path connecting the circulator and nozzle, non-return valves within the paths providing for uni-directional flow from the nozzle through the efflux path to the circulator and from the circulator through the flushing path to the nozzle. A debris-collecting filter element is disposed within the efflux path within the barrel. The filter element and valves may be in the form of a replaceable cartridge. The valves may be constructed as a shuttle with joined oppositely operating valve plates. The valves may also comprise a resilient flap member with a flap formed therein, both the flap member and flap being independently operable and defining the two valves.

  • Patent number: 4627838
    Abstract: In a catheter (10) with wings (26,27) which are brought into a retaining disposition by pulling on a distal tip insert (11) with an actuating means (16) manipulated from the proximal end of the catheter, the retaining surfaces (10B,31) move freely into their co-operative holding disposition from a transport disposition because they are spaced from one another in the transport disposition. The actuating means (16) is preferably a trocar and has a sleeve (19) which not only drives the catheter into position but also controls liquid flow down the catheter tube. Stop surfaces (29,10C) prevent "overshoot" of the wings past the desired retaining disposition and make more positive the disengagement of latching surfaces (22,23) between the tip element (11) and the trocar (16).

  • Patent number: 4540156
    Abstract: A valve for a body fluid storage container comprises a valve body (11) and a manually operable valve member (10) rotatable in a through aperture (14) therein, between an open disposition in which a touch surface (30,31) of the valve member stands away from the fluid flow path (15) through the valve and a closed disposition in which it lies close to it. The valve member has a unitary construction in which a first limb (33) extends from an insert portion (37) of the valve member, at one end of the through aperture, to the touch surface, and a second limb extends from the touch surface to a retaining portion (40) which engages, at the other end of the through aperture, with a leading end (42) of the insert portion to hold the valve member in position in the valve body. This two-part valve provides a cheap disposable item for use with disposable containers.
