  • Patent number: 11154682
    Abstract: A ventilation tube unit (2), for connection to a medical ventilator, includes an outer tube (4) with a tubular connection device (18) with a jacket-side branch (24, 28), for connecting a medical unit such as a water trap, arranged between a first outer tube part (20) and a second outer tube part (22). An inner line (6) is arranged within and extends with the outer tube (4) between two port connectors (8). Each outer tube part (20, 22) includes a variable-length outer tube part that can be varied between a compressed state and an expanded state. The connection device (18) is displaceable in the longitudinal direction (A) relative to the inner line (6) by a compression of one outer tube part (20) and a corresponding expansion of the other outer tube part (22). A ventilation system with at least one such ventilation tube unit is also provided.

  • Patent number: 11051700
    Abstract: 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.

  • Publication number: 20210095740
    Abstract: 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).

  • Patent number: 10376152
    Abstract: A measuring device (10) has at least one sensor (16, 18), which can be applied to the skin surface (12) of a patient for detecting a measured value with the sensor (16, 18). The device (10) has two contact surfaces (20, 22) on an underside (24), which is intended for being in contact with the skin surface (12) of the patient. A current detecting (32, 34), detects a measuring current (30) resulting from a particular effective electric resistance between the contact surfaces (20, 22). A method for operating such a measuring device (10) and a system with such a measuring device (10) are also provided.

  • Patent number: 10213591
    Abstract: 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.

  • Publication number: 20170316671
    Abstract: A medical sensor extension cable includes a sensor electrical contacting interface, that receives an electrical sensor signal which indicates a physiological parameter of a patient, and a wired data interface, that connects to a data network device. An integrated circuit determines measured values of the physiological parameter based on the sensor signal, to provide an alarm limit value, to establish a presence of an alarm event as a function of a comparison of the measured values and the at least one alarm limit value, as well as to provide data elements, which indicate the measured values and the presence of the alarm event in the event of an alarm, via the data interface. A data network device includes a data connection interface for a data interface of the extension cable. A display interface provides a display signal, which indicates the measured values and the alarm limits.

The medical electrode includes an outer carrier and at least one inner carrier (3, 3?, 3?). The outer carrier and the inner carrier are connected at a defined number of geometrically distributed points (2). The points (2) form an outer edge (4) of the inner carrier and are perforated, so that the outer carrier and the inner carrier can be separated at these points (2). An adhesion area (5) is formed on the underside of the outer carrier (1) and of the inner carrier for adhering the medical electrode to the patient body surface. A contact element (7) is provided with a conductive area arranged concentrically to the contact element (7) for establishing contact with the body surface of the patient. The contact element (7) and the conductive area (8) are arranged within the inner carrier.
