Patent number: 7789866Abstract: An ostomy bag with a filter assembly having a gas filter and a pre-filter for preventing or delaying solid/semisolid matter and liquid from reaching the gas filter. The pre-filter is at least substantially flat and comprises a number of constrictions, such as ribs extending along and between two inner surface parts of the channel. These constrictions/ribs form narrower and wider passages where the gas may more quickly pass a narrow passage and where the wider passages tend to receive and hold the liquid, solid matter and semisolid matter. The constrictions may be provided as a single, monolithic element, such as an extruded element.Type: GrantFiled: December 23, 2004Date of Patent: September 7, 2010Assignee: Coloplast A/SInventors: Lars Bo Poulsen, Bjarne Worsoe, Morgens Kristensen, Per Ole Nielsen, Hans Olsen

Patent number: 7367965Abstract: An ostomy appliance with a front wall and a rear wall of flexible material forming a bag, the rear wall having an opening into the bag by which waste material can enter the bag. The bag has two or more vents through which gas may escape from the bag and a filter device covering each vent. Each filter device has gas inlet and outlet openings in communication with a respective filter body so that in use gas flows through the filter device from the inlet opening through the filter body to the outlet opening. The inlet openings communicate with the inner space of the bag and are located near the border of the bag, being spaced at an angle of at least 45 degrees along radii of a circle of reference having a perimeter concentric with the waste opening of the bag.Type: GrantFiled: February 26, 2003Date of Patent: May 6, 2008Assignee: Coloplast A/SInventors: Lars Bo Poulsen, Per Ole Nielsen

Patent number: 7223260Abstract: The collecting bag has a bag member formed by a first and a second film blank, and a discharge portion that is foldable and unfoldable to bring the discharge portion from an open unfolded condition to a closed folded condition and vice versa. A first plate member is positioned on the first film blank and a second plate member is positioned on an extension of the second film blank Each plate member is formed from a relatively stiff material, and the distance between the distal edge of the first plate member and the proximal edge of the second plate member is smaller than the thickness of the first plate member. When folding the discharge portion, the distal edge of the first plate member acts as a pivot, and a stretching effect is created on the second film blank to effectively seal the discharge opening without deformation of the plate members.Type: GrantFiled: October 1, 2003Date of Patent: May 29, 2007Assignee: Coloplast A/SInventors: Soren Hansen, Lars Bo Poulsen

Patent number: 6858023Abstract: In a reusable collecting bag such as a stoma bag (1) having a narrowed discharge portion (8) including a slit-like discharge opening in the vicinity of its distal end the discharge portion (8) is brought from an open position for emptying the bag through the discharge opening (9) and a closed position of use by folding and unfolding the discharge portion (8) about at least one folding line (24) transverse to the longitudinal direction of the discharge portion (8). To avoid or reduce faecal contamination of the discharge portion (8) in connection with emptying of the bag a series (16, 18) of sequentially peelable stacked protective members (17, 19) is applied to each of two surface sections of the discharge portion (8) adjacent the discharge opening (9).Type: GrantFiled: August 14, 2001Date of Patent: February 22, 2005Assignee: Coloplast A/SInventor: Lars Bo Poulsen

Patent number: 6780172Abstract: The collecting bag comprises a bag member (1) formed by two film blanks with joined edges, an inlet opening being provided in one of said film blanks surrounded by connecting elements for connection of the bag to a body orifice. The bag is emptied through a narrowed, elongated discharge portion (8) ending in a discharge opening (9). Sealing plates (35a,35b) made from a resilient material, eg. foam, are attached to the discharge portion (8) at or near the discharge opening (9) to close the discharge opening by folding of the discharge portion (8).Type: GrantFiled: November 22, 2002Date of Patent: August 24, 2004Assignee: Coloplast A/SInventors: Hans Olsen, Lars Bo Poulsen, Birte Vestbo Andersen, Søren Hansen, Martin Von Bulow

Publication number: 20040068243Abstract: The collecting bag has a bag member (2) formed by a first and a second film blank (2,3), and a discharge portion (8) that is foldable and unfoldable to bring the discharge portion from an open unfolded condition to a closed folded condition and vice versa. A first plate member (21) is positioned on the first film blank (2) and a second plate member (22) is positioned on an extension (3a) of the second film blank (3). A locking device is provided at the discharge portion for locking the bag in the closed folded condition of the discharge portion. Each plate member (21,22) is formed from a relatively stiff material, and the distance (d) between the distal edge (21b) of the first plate member (21) and the proximal edge (22a) of the second plate member (22) is smaller than the thickness of the first plate member.Type: ApplicationFiled: October 1, 2003Publication date: April 8, 2004Inventors: Soren Hansen, Lars Bo Poulsen

The bag is emptied through a narrowed, elongated discharge portion ending in a discharge opening. A closure device provided at the discharge portion for bringing the bag from an open to a closed position of use includes a first closure means at the proximal or distal end of the discharge portion and a second closure means. The closure device is arranged for opening and closing of the bag in two distinct stages by successive operation of the first and second closure means.Type: GrantFiled: May 18, 2000Date of Patent: January 8, 2002Assignee: Coloplast A/SInventors: Hans Olsen, Lars Bo Poulsen, Birthe Vestbo Andersen, Søren Hansen, Michael Hansen
