  • Patent number: 10905864
    Abstract: A levelling device for positioning of a medical device in relation to a patient is disclosed. The levelling device comprises a tube having fluid communication between a first end and a second end, wherein the first end is configured for connection to the medical device and the second end is configured for connection to the patient. The levelling device comprises a control unit connected to a sensor, wherein the sensor is configured to transmit sensor data to the control unit which is indicative of a pressure difference between the first and second end of the tube, and an actuator connected to the control unit, wherein the actuator is configured to connect to the medical device and to arrange a position of the medical device in relation to the patient in dependence on said pressure difference.

  • Publication number: 20200323469
    Abstract: A biosensor for detecting a biomarker in a bodily fluid, secretion or exudation is described that includes a first electrode, a second electrode, an electrode coating and a mechanical electrode stabilizer. The biomarker is an enzyme catalyzing a chemical reaction in which a singularity or plurality of constituents of the electrode coating are chemically altered by the breaking of covalent chemical bonds when being in contact with the same. The electrode coating can be a natural or synthetic substrate of the biomarker. The first electrode and the second electrode are electrically conductive and are kept in a substantially constant and uniform distance from each other by means of the mechanical electrode stabilizer. The exposed electrically conductive surface of at least one of the first electrode and the second electrode are substantially fully covered by the electrode coating.
