Patent number: 10695504Abstract: A drug delivery system comprises means to create a log of expelled dose amounts of drug. Stored dose amounts determined within a given time period are combined to a single combined dose amount. The given time period is initiated by a detected expelling event taking place (i) a given amount of time after a previous detected expelling event, or (ii) after a given detected action. By this arrangement it is possible to create a log corresponding to what a user considers to be a single dose, i.e. combining “split doses” to create a single log entry for a per se split dose.Type: GrantFiled: April 3, 2014Date of Patent: June 30, 2020Assignee: Novo Nordisk A/SInventors: Preben Mikael Nielsen, Nikolaj Frogner Krusell, Jens Christian Andersen, Nikolaj Eusebius Jakobsen

Patent number: 10213554Abstract: A medial assembly comprises a logging first unit adapted to be mounted on a drug delivery device second unit from a fully un-mounted to a fully mounted position along a path. The first unit comprises a switch operatable between an off- and an on-state when the first unit is mounted on the second unit, the switch being in the on-state when the first unit is mounted within a first distance from the fully mounted position, and in the off-state when the first unit is mounted outside the first distance from the fully mounted position, and a snap lock operatable from an initial state through an expanded state to a snap-in state when the first unit is mounted on the second unit, the snap lock being in the snap-in state when the first unit is mounted within a second distance from the fully mounted position, the second distance being shorter than the first distance. By this arrangement it is ensured that the switch will be in the on-state before the snap lock is in the snap-in state.Type: GrantFiled: February 25, 2016Date of Patent: February 26, 2019Assignee: Novo Nordisk A/SInventors: Jens Christian Andersen, Preben Mikael Nielsen, Nikolaj Eusebius Jakobsen, Nikolaj Frogner Krusell

Patent number: 10183119Abstract: An add-on dose logging device for a pen device consumes energy when the sensors are operated and when the display is active. By using cap-off event to activate the sensor system only, and using cap-on event to de-activate the sensor system and activate the display for a given time to display a sensed dose, power consumption can be reduced without changing the user-interface and without adding any components apart from a switch.Type: GrantFiled: June 4, 2015Date of Patent: January 22, 2019Assignee: Novo Nordisk A/SInventors: Jens Christian Andersen, Nikolaj Frogner Krusell, Claus Bagger

Patent number: 10159797Abstract: An add-on logging device (100, 300) mounted to a drug delivery device is turned on when the cap is removed. After a given amount of time in inactivity the sensor means of the add-on device is turned off automatically to save energy. If the user takes a dose of drug this is not detected as the add-on device is only turned on when the cap is removed. According to the present invention a warning message is provided when the cap is re-mounted after the sensor means has been turned off automatically, the warning message indicating to a user that an expelled dose may not have been detected.Type: GrantFiled: June 4, 2015Date of Patent: December 25, 2018Assignee: Novo Nordisk A/SInventors: Jens Christian Andersen, Nikolaj Frogner Krusell, Preben Mikael Nielsen

Patent number: 10155090Abstract: System comprising a sensor assembly (3, 4, 5, 6) adapted to measure a magnetic field, and a moveable element (1) adapted to be moved relative to the sensor assembly between two positions by a combined axial and rotational movement, the rotational movement having a pre-determined relationship to the axial movement. A magnet (3) is mounted to the moveable element and configured to generate a spatial magnetic field which relative to the sensor assembly varies corresponding to both the axial and rotational movement of the magnet and thus the moveable element. A processor is configured to determine on the basis of measured values for the magnetic field an axial position of the moveable element.Type: GrantFiled: October 5, 2012Date of Patent: December 18, 2018Assignee: Novo Nordisk A/SInventors: Andre Larsen, Henrik Riehm Soerensen, Laurits Hoejgaard Olesen, Nikolaj Frogner Krusell, Jens Christian Andersen
