  • Patent number: 8748689
    Abstract: An absorbent article, e.g. tampons, sanitary napkins, panty liners and the like, and the process for their preparation in which a hydrophobic and/or cationactive layer is attached to a conventional absorbent layer, for the binding of microorganisms, specifically for treating or alleviating or prophylactically preventing vaginal fungal infections.
    Type: Grant

  • Publication number: 20060149196
    Abstract: Incontinence device for men formed as a pouch with an opening for insertion of penis or penis and scrotum. At one side of the pouch is one ore more elastic members located. The pouch is opened by pressing at the side edges of the elastic member so the pouch opens for insertion of penis or penis and scrotum. By the elastic restoration force of the elastic member the pouch is closed around penis or penis and scrotum and holds it in place. The elastic member is prepared so it always only bends in one direction when pressed upon from booth sides in its longitudinal direction which opens the pouch. The device is also equipped with friction layers on the inside of the pouch in order to further prevent penis from slipping out of the pouch.

  • Publication number: 20060129080
    Abstract: A wound dressing product, combining both a traditional dressing with a mounted absorbent material and a hydrophobic fabric attached thereto, which is to be placed towards the wound, and is capable of binding unwanted microorganisms. The wound dressing product protects the wound, absorbs exudate and reduces the number of pathogenic microorganisms, without using antimicrobial substances, and consists of three bonded layers: hydrophobic cellulose acetate fabric which binds microorganisms, an attached efficient absorbent material, and a backing (cover) which is preferably visually transparent, semi-permeable and self-adhesive.

  • Publication number: 20040093671
    Abstract: A hygiene mat principally consisting of a liquid absorbing layer (2, 4) with or without a liquid permeable surface layer (1) and a liquid barrier (3), consisting of expanded polymers with closed cells and low density, 5-40 kg/m3, and a specific resistance to bending of between 0.05 and 3.5 g/cm, and a thickness of between 0.2 and 3.5 mm. With this structure a hygiene mat is obtained at a low cost with very good comfort and stability.

  • Patent number: 4892535
    Abstract: An absorbent pad such as an incontinence pad comprises a liquid-impervious back sheet with spaced islands of absorbent material thereon. A liquid-pervious cover sheet has pockets formed therein, in which the islands of absorbent material are disposed. The cover sheet is secured, either adhesively or by heat sealing, directly to the impervious sheet along lines that separate the islands of absorbent material and the pockets that contain them. The pad is formed by applying a strip of cover sheet material to a rotating multi-perforate drum and forming the pockets in the cover sheet material either mechanically, or by drawing hot air inwardly through the holes in the drum in the case of a heat-deformable material such as polypropylene fibers. The drum then rotates past a pocket-filling station, where absorbent material such as cellulose fluff is drawn into the pockets by vacuum applied internally of the drum.
