Abstract: A valve comprises a housing in which a movable valve element having first and second valve members is disposed. A plurality of ports are disposed in the housing, and first and second seal portions are connected to the housing. At least one of the first seal portion and the first valve member is deformable such that, when only the first seal portion is in a sealed configuration with the first valve member, deformation allows the second seal portion to be brought into a sealed configuration with the second valve member, and/or at least one the second seal portion and the second valve member is deformable such that, when only the second seal portion is in a sealed configuration with the second valve member, deformation allows the first seal portion to be brought into a sealed configuration with the first valve member.

Abstract: A patient interface and a patient interface system comprise a responsive material and a method for preventing the formation of red marks due to wearing a patient interface that is pressing against the skin of a patient for a longer time and/or for reducing air leakages of the patient interface that may result from an unintended shift of the patient interface on the patient's face. The responsive material is configured for alternating the pressure exerted by the cushion element on the patient and/or the area on the patient where the pressure is exerted by the cushion element in response to a physical quantity acting on the responsive material. The formation of red marks and of air leakages can be reduced or even avoided by means of the responsive material.

Abstract: The invention provides a patient interface (10) comprising a patient interface element (12, 14, 15) for delivering breathing gas to a patient, and a forehead support (30). One of the forehead support and the patient interface element comprises a shaft (50) and the other comprises a hollow tube (51) in which the shaft is received, with the shaft slidable within the tube to permit adjustment of the position of the forehead support relative to the patient interface. The shaft and hollow tube are rotatable between a free and locked configuration. This provides a simple to use adjustment mechanism with few components.

Abstract: The invention provides a patient interface (10) comprising a patient interface element (12, 14, 15) for delivering a breathing gas to a user and a forehead support (30). One of the forehead support and the patient interface element comprises a shaft (60) and the other comprises a hollow tube (62) in which the shaft is received, with the shaft slidable within the tube to permit adjustment of the position of the forehead support relative to the patient interface element. One of the shaft and hollow tube are elastically deformable between a deformed configuration in which the shaft can be slid within the tube and a released configuration in which the sliding of the shaft within the tube is blocked.

Abstract: The present invention relates to acquisition of medical image information of an object. In order to provide a user-friendly alignment of X-ray tube and a detector, optionally combined with an anti-scatter grid, an alignment arrangement is proposed, which comprises a tube attachment with a first light projection device and a detector attachment with a second light projection device. The first and second light projection devices each generate a light pattern on a projection surface. The tube attachment and the detector attachment can be brought into a correct spatial arrangement relative to each other by bringing the first light pattern in a predetermined spatial relation with the second light pattern on the projection surface.

Abstract: The present invention relates to acquisition of medical image information of an object. In order to provide a user-friendly alignment of X-ray tube (18) and a detector (24), optionally combined with an anti-scatter grid, an alignment arrangement (200) is proposed, which comprises a tube attachment (26) with a first light projection device (28) and a detector attachment (34) with a second light projection device (36). The first and second light projection devices each generate a light pattern (30, 38) on a projection surface (32). The tube attachment (26) and the detector attachment (34) can be brought into a correct spatial arrangement relative to each other by bringing the first light pattern in a predetermined spatial relation with the second light pattern (38) on the projection surface.

Abstract: There is provided a valve (2, 102, 302, 402) which comprises a housing (4, 04, 204, 304, 404) in which a movable valve element (6, 106, 206, 306, 406) having first and second valve members (14a, 14b; 114a, 114b; 214a, 214b; 314a, 314b; 414a, 414b) is disposed. A plurality of ports (A-E) are disposed in the housing, and first and second seal portions (8a, 8b; 10a, 10b; 108a, 108b; 110a, 110b; 208a, 208b; 210a, 210b; 308a, 308b; 310a, 310b; 408a, 408b; 410a, 410b) are connected to the housing. The first and second seal portions each have a sealed configuration in which first and second pairs of ports are sealed from one another with the first and second valve members respectively.
