Patent number: 11898646Abstract: The present invention relates to adjustable flow control valves, for example to an Adjustable Pressure Limiting (APL) valve. The adjustable valve (2) described comprises a valve body (4) comprising a valve seat (6), a valve member (10) movable relative to the valve seat (6), a first valve cap (20), a second valve cap (50) and a biasing element (30) to bias the valve member (10) away from the first valve cap (20). The first valve cap (20) is movable to increase the biasing force applied by the biasing element (30). The second valve cap (50) is engageable with the first valve cap (20) to prevent such movement of the first valve cap (20) beyond a selected position, but to allow movement of the first valve cap (20) in an opposite direction, way from said position.Type: GrantFiled: June 25, 2020Date of Patent: February 13, 2024Assignee: INTERSURGICAL AGInventors: David Simon Bottom, Christopher Edgerly Booth, Simon Robert Payne, Richard Francis Bowsher

Patent number: 11058839Abstract: A sealing cushion for a respiratory mask assembly has a patient interface portion having a resiliently deformable membrane for engagement with a patient's face, and an aperture formed therein for receiving a nasal and/or mouth region of the patient's face. An inner surface of the deformable membrane comprises a plurality of projections arranged in separate groups of projections positioned in a plurality of localized regions of the deformable membrane. The projections in each of the separate groups of projections are arranged such that each projection in the group of projections engages with an adjacent projection in the group of projections when the deformable membrane is deformed during engagement of the deformable membrane with the patient's face, in use, thereby providing the deformable membrane with an increased resistance to further deformation.Type: GrantFiled: December 23, 2014Date of Patent: July 13, 2021Assignee: INTERSURGICAL AGInventor: Richard Francis Bowsher

Patent number: 10238826Abstract: This invention relates to a respiratory mask for delivering an inhalation fluid to the airways of a wearer. The respiratory mask includes a body of generally concave shape and having a peripheral edge, the body being adapted to provide a cavity in use about the mouth and nose of a wearer such that the inhalation fluid can be inhaled by the wearer from the cavity. The respiratory mask includes a resilient seal formation depending from at least a portion of the peripheral edge. The resilient seal formation includes both an inwardly and outwardly depending lip portion relative to the peripheral edge of the body. The mask may accommodate a range of facial dimensions whilst still retaining an effective seal.Type: GrantFiled: March 27, 2012Date of Patent: March 26, 2019Assignee: Intersurgical AGInventor: Richard Francis Bowsher

Patent number: 8646449Abstract: An anti-asphyxiation valve is disclosed, which is adapted for incorporation within a breathing circuit including a ventilator. The valve comprises one or more apertures for enabling passage of gas between the breathing circuit and the atmosphere, and a valve member deformable between an open configuration in which the one or more apertures are at least partially exposed and the passage of gas therethrough is enabled, and a closed configuration in which the valve member occludes the one or more apertures and the passage of gas therethrough is substantially prevented. The valve member is adapted such that the pressure within the breathing circuit at which the valve member deforms from the open configuration to the closed configuration is greater than the pressure within the breathing circuit at which the valve member deforms from the closed configuration to the open configuration.Type: GrantFiled: November 13, 2008Date of Patent: February 11, 2014Assignee: Intersurgical AGInventor: Richard Francis Bowsher
