  • Patent number: 11898678
    Abstract: A bag connector system includes a first coupling element, with a self-closing seal and a housing having a fluid inlet port and a fluid outlet port, and a second coupling element, with a housing having a fluid inlet end and a fluid outlet end. The fluid inlet end is configured to displace the self-closing seal when inserted into the fluid outlet port of the first coupling element. A bag connector system optionally includes a locking mechanism to maintain the first coupling element and second coupling element in a coupled state. Uncoupling of the first and second coupling elements results in minimal fluid contamination on the outer surfaces of the coupling elements. The bag connector systems provided herein are included in medical appliances for waste management.

  • Publication number: 20220054297
    Abstract: A stoma adapter is described that is especially suited to a recessed stoma or a flush stoma. The stoma adapter effectively extends the discharge passage from the stoma, protects peristomal skin, and forms a bridge at the interface between the stoma and an ostomy appliance. The stoma adapter contains a substantially unobstructed discharge passage, at least for effluent flowing in a discharge direction. The stoma adapter includes a seal for sealing against the bowel wall. The stoma adapter has collapsing, expanding, flexible and reinforced designs.

  • Patent number: 10864107
    Abstract: A stoma extender includes a first end for insertion into a stoma for diverting stomal effluent into the stoma extender before the effluent exits the stoma; a second end for remaining external of the stoma, for providing a discharge exit for stomal effluent; and a conduit portion coupled between the first and second ends for communicating stomal effluent through the stoma extender, wherein the length of the conduit portion is adjustable stably, to permit adaptation of the stoma extender to an individual's stoma.

  • Patent number: 8939952
    Abstract: A rectal appliance with a tubular member defining a communication passage for body waste, and first and second inflatable chamber portions carried on the tubular member for forming internal and external seals with respect to the anus. One or both of the inflatable chamber portions have a partly flared shape. The second inflatable chamber portion has a low external profile, and a concave sealing surface. The inflatable chamber portions are defined at least partly by a common flexible membrane that is constrained near a middle region to define a narrow waist between the two inflatable chamber portions.

  • Patent number: 8388586
    Abstract: An ostomy appliance is disclosed with an inflatable seal for sealing against the stoma. The inflatable seal has a first inflatable chamber portion for fitting inside the stoma to seal against the internal tissue. The inflatable seal also has a second inflatable chamber portion for sealing externally against the stoma and peristomal skin. In one embodiment, a tube extends through the inflatable seal to provide a communication passage for discharge of body waste without removing the inflatable seal. The tube floats with respect to an adhesive mounting member to allow a waist between the first and second inflatable chamber portions to self-locate in the stoma.

  • Patent number: 7947025
    Abstract: A drainable urine pouch includes a discharge portion that is foldable between a discharge position and a closed position. A security flap is sealed to both walls of the pouch by a through weld, to define a baffle near the discharge portion. The discharge portion includes a constriction, and a stepped profile with multiple step stages. The discharge portion has one or more bias members. A drainage adapter is releasably coupled to the discharge portion. The drainage adapter has a plug with a shoulder for abutting the constriction in the discharge portion, to locate the adapter correctly for obtaining a liquid-tight seal.

  • Publication number: 20110060300
    Abstract: An aspiration system is disclosed for removing body liquid (e.g. urine or a secretion) discharged by the human body. The aspiration system comprises a body interface device with a liquid sensor, and an aspiration unit coupled to the body interface device. The liquid sensor comprises a temperature sensor and/or a resistance bridge. The aspiration unit includes: a vacuum chamber; a pump for pre-charging the vacuum chamber with a vacuum; a valve coupled between the vacuum chamber and the body interface device; and a control circuit for controlling the valve to apply aspiration suction from the vacuum chamber to the body interface device in response to detection of body liquid at the liquid sensor.

  • Patent number: 7722585
    Abstract: A drainable ostomy pouch has an outlet. Reinforcing members at the outlet are deformable by application of manual pressure at their ends to distend the outlet. The lateral edges of the reinforcing members may be offset, which encourages the reinforcing members to consistently bend away from each other. A peelable distributed mechanical engagement fastener secures the outlet in a folded condition. The fastener parts are hook-hook type plastic extrusions, and provide a snap-engagement. A security flap is foldable under the outlet when in its folded condition. The outlet is released in two stages.
