  • Publication number: 20230390101
    Abstract: An ostomy appliance comprising: first and second walls connected to each other at or near their peripheries, the first wall having a stoma-receiving opening; a connection member connected to the first wall for attaching the appliance to a user; an aperture located in either of the first and/or second walls for permitting waste gases to exit the appliance; and a multi-layer filter positioned adjacent and covering the aperture on an exterior surface of the respective first and/or second wall. A layer of the filter is hydrophobic and the hydrophobic layer is positioned directly adjacent the respective first and/or second wall. The hydrophobic layer has a first side and a second side, where the first side is connected directly to the respective first and/or second wall, and the connection holds the multi-layer filter relative to the wall.

  • Patent number: 11678703
    Abstract: Embodiments of the present disclosure generally relate to coated substrates having, e.g., anti-viral properties, to articles including the coated substrates, and to processes for making such coated substrates and articles. In an embodiment, a mask for preventing infection by a virus is provided. The mask includes a coated substrate having a breathing resistance (95 L/min, EN 149:2001) of about 6 mbar or less and a water droplet absorption time of less than about 5 seconds. The coated substrate includes a non-woven fabric having a weight of about 120 g/m2 or less according to ASTM D3776, and mineral oxide particles, iron oxide particles, or both, coupled to at least a portion of the non-woven fabric.

  • Patent number: 11559425
    Abstract: An ostomy appliance including: first and second walls connected to each other at or near their peripheries, the first wall having a stoma-receiving opening; a connection member connected to the first wall for attaching the appliance to a user; a waste collecting chamber defined by the first and second walls for receiving waste and/or gas from the stoma-receiving opening; a further chamber defined by at least third and fourth walls which are connected to each other; a gas opening provided in either or both of the third or fourth walls for permitting waste gases to pass therethrough from the waste collecting chamber; a gas vent for permitting gases in the further chamber to escape to atmosphere; and wherein movement of the first and second walls away from each other, from waste or gases entering the waste collecting chamber, increases or at least maintains the volume of the further chamber.
