Patent number: 11051700Abstract: A double temperature sensor determines the body core temperature of a living being. The double temperature sensor includes a sensor block (2), which on one side carries a first temperature sensor (4) provided for placing on the skin surface and on the other side carries a second temperature sensor (5) spaced from the first. An evaluating unit calculates the body core temperature using the measured values of the first and second temperature sensors. The sensor block (2) is held in a hood-shaped housing shell (1) which is shaped in such a manner that the first temperature sensor (4) on the sensor block and the peripheral outer edge (8) of the housing shell (1) spaced therefrom lie in one plane. When the housing shell (1) is lying on the skin surface, the sensor block (2) is surrounded by an air-filled cavity closed off by the housing shell.Type: GrantFiled: March 14, 2014Date of Patent: July 6, 2021Assignee: Drägerwerk AG & Co.

Publication number: 20210095740Abstract: A clamping device (1), for coupling a sensor cable (2) to an electrical contact, has a circumferential, elastically deformable frame (3). The frame has an outer surface (5), an inner surface (6) facing an inner area (4), a first end face (7) and an opposite second end face (8). A contact device (9) is held at the frame and extends into the inner area. A counter-holding device (10), at the frame, has a counter-holding element (11). The contact device and the counter-holding device form a receiving space for holding the electrical contact in a holding position. A relative movement into a first released position is brought about by a pressing on both sides from the outside against the outer surface on a first frame axis (12). A second released position is provided by pressing on both sides against the frame outer surface on a second frame axis (13).Type: ApplicationFiled: September 25, 2020Publication date: April 1, 2021Inventor: Thomas GRAßL

Patent number: 10213591Abstract: A second part extending around a first part in a plugged-together state. The second part has snap-in element with an inwardly protruding projection for meshing with a complementary recess on an outer surface of the first part to hold the second part fixed in the axial direction on the first part. Both parts have a central passage opening. One part has an end area expanding towards the outlet opening in a connection area, and the other part is connected to an elastic section, arranged in its interior. The front end of the elastic section is pressed into contact with the expanded end area of the opposite part. The projection of the snap-in element maintains the first and second parts meshed together, so that the elastic section exerts a sealing function due to the pressure on the expanding end area.Type: GrantFiled: June 29, 2009Date of Patent: February 26, 2019Assignee: DRÄGERWERK AG & CO.
