  • Patent number: 7857796
    Abstract: An ostomy appliance is described in the form of a controlled discharge device for controlling discharge from the stoma and/or an ostomy pouch for collecting discharged waste. The appliance may include one or more of: an elastomeric stoma seal for providing a seal around or directly against the stoma; a stoma occluder for occluding the stoma without passing internally into the stoma; a peristomal foam wall; a confinement seal for confining at least solid excreta to a confinement region adjacent to the stoma; a stowable collector bag; and interchangeable controlled discharge devices and ostomy pouches. The foam wall may provide a barrier to stool, but allow escape of flatus. The foam wall and/or the stoma occluder and/or the confinement seal may apply a force in a direction to increase the sealing force on the stoma seal.

  • Patent number: 7842018
    Abstract: A colostomy bag having a cleansing system wherein the bag is cleaned while in its operable position associated with the person. More specifically, the system mounts a manifold within the colostomy bag with an access to water under pressure from outside, the manifold providing a spray dispersion of fluid, or cleansing water, at the top of the bag and gravity then drips it down through the bag and out the open bottom end, with the residue of the bag being washed out by the water and passing into a toilet. The user can thus easily flush the bag to complete cleaning with all residue from the bag passing into the toilet. A water source from the toilet itself, or other suitable water supply, provides the water under pressure to the manifold inside the top of the colostomy bag.

  • Patent number: 7731702
    Abstract: A portable closed wound drainage system that uses a pouch shaped dressing which is inserted into a wound. At least a portion of the outer surface of the pouch is porous to allow exudates to enter. Exudates are removed from the pouch by flexible tubing which is secured inside the pouch at one end and secured at the other end to a portable drain/suction unit. The pouch contains porous material. The tubing can have a single or multi-lumen structure. The pouch and the tube are sealed by a flexible sealing material which is applied to the outer surface of the skin. A cosmetic cover sheet is attached to the patient's skin over the closed wound drainage system.

  • Patent number: 7585293
    Abstract: Urine collection apparatus is provided which can be used to assist bedridden and/or incontinent patients, particularly female patients. The apparatus includes a urine collector which is shaped for location against the perineal region of a patient adjacent the urethra. The urine collector comprises a hollow body having opposed ends in which an inlet for air and an outlet for air and urine are formed, respectively. The body has a central region between the end regions with a reduced cross-sectional area. This effectively creates a venturi adjacent the patient's urethra when air passes through the collector. The apparatus includes a urine receptacle with an inlet for receiving air and urine from the collector, and an outlet for air which is connectable to a source of low pressure. The source of low pressure will typically be an impeller driven by an electric motor, which creates a sufficiently strong air flow through the apparatus to entrain urine and transport it to the receptacle.

  • Patent number: 7422578
    Abstract: A connecting ostomy device for coupling a collecting bag to a fixing device (10) includes a first joining part (16) connected to the fixing device and a second joining part (12) connected to the collecting bag. The joining parts interact by adhesion in a plane practically perpendicular to the axes of orifices (14) of the collecting bag of the fixing device in such a way that the transmission of the bag weight and the impermeability thereof are ensured by adhesion. The additional fixing elements (18, 20) ensure the alignment of the orifices (14) of the fixing device (10) and the collecting bag in a position thereof which is practically determined before the removal of the protective film from an adhesive surface. The connecting device is used for ostomy.
