Abstract: 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.

Abstract: Add-on module (100) for logging the value of an expelled dose from a pen-type drug injector (200), comprising a magnetic sensor system comprising first and second sensor means (745/746) as well as a mechanical dose setting and expelling mechanism comprising a magnetic clutch element (240/740) which rotates during drug expelling. The system further comprises processor means configured to determine (i) on the basis of measured values from the first sensor means, a rotational position of the clutch element, (ii) on the basis of measured values from the second sensor means, a high-speed condition in which the rotational speed of the clutch element exceeds a given threshold level, and (iii) indicate an error state if the high-speed condition is detected.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a medical injection system comprising an injection device (100) and a dose capturing unit (20). The injection device (100) incorporates expelling means (101) for setting and expelling a set dose amount of a drug from a reservoir. The expelling means (101) further comprises mechanical energy storage unit adapted to drive the expelling movement and a movable dosing member (350). In one form the dose capturing unit (20) is configured for being releasably attached to the injection device (100). The dose capturing unit (20) comprises a dose sensor (20d) configured to capture data relating to the movement of the dosing member (350) during dose expelling. When the dose capturing unit (20) is attached to the injection device (100), the systems forms a speed limiting means (F, M) to limit the speed of the dosing member (350) during dose expelling so that a force that counteracts the force exerted by the mechanical energy storage unit is generated.

Abstract: The invention provides a kit comprising a medical accessory device and a dummy unit. The accessory device comprises first attachment means configured for releasable attachment of the accessory to co-operating second attachment means on an original device having an outer surface defining an original device space envelope. The dummy unit comprises a presentation surface on its external surface, a folded or rolled sheet, as well as dummy attachment means configured for releasable attachment of the accessory device to the dummy unit in co-operation with the first attachment means. By this arrangement the mounting of the accessory device on the original device can be demonstrated on the dummy unit in a simple and effective way.
