  • Publication number: 20200279646
    Abstract: A method for controlling operation of a medical device in a medical system having a medical device, a communication device including a remote control for the medical device, and a safety device adapted for data communication with the communication device. Input data is provided and processed by a first calculation to thereby provide a first calculation result. The input data is processed by a second calculation executed separately from first calculation to thereby provide a second calculation result. The first and second calculation results are compared. When the first and second calculation results are found equal, remote control of the medical device by a medical device application running on the communication device is allowed. When the first and second calculation results are found not equal, the medical device application running on the communication device for remote control of the medical device is prevented.

  • Publication number: 20200197604
    Abstract: Disclosed is an infusion device controller, the infusion device controller being designed to control a drive for metered drug infusion out of a drug reservoir according to a set of infusion regimes. The infusion device controller is designed to control infusion in a series of scheduled infusion events and is further designed to determine, for an infusion event volume that is infused in a given scheduled infusion event, an assignment between volume fractions of the infusion event volume and infusion regimes in an interlaced manner.

  • Publication number: 20200179604
    Abstract: This disclosure concerns a medical device designed for delivering a medical fluid or designed for controlling delivery of a medical fluid, and to a method of operating such a medical device. The medical device comprises a user interface associated with an electronic circuit connected to a first port and to a second port of a controller. The electronic circuit enables the controller to detect actuation of the user interface. The controller is configured to execute the following sequence of steps: first step: configure the first port as an output port and to apply a first signal to the first port; second step: to acquire a second signal from the second port; and third step: to determine on the basis of the second signal if a short circuit has occurred and to generate a short circuit alert signal if applicable.

  • Publication number: 20200171237
    Abstract: Disclosed is a method for scheduling a refilling of a secondary reservoir of an ambulatory infusion system out of a primary reservoir storing a liquid drug. The method includes repeatedly and automatically carrying out a filling volume assessment routine. The filling volume assessment routine includes: determining, at a present point in time, an estimated filling volume of the secondary reservoir at a future estimation point in time, the future point in time being an estimation time interval after the present point in time, and determining in dependence of the estimated filling volume, if the secondary reservoir shall be refilled at the present point in time.

  • Publication number: 20200158785
    Abstract: A method and device for testing a battery that powers a body-wearable medical device. The battery is contacted via battery contacts and a capacitor is arranged in parallel with the battery contacts. During the battery test, a first capacitor voltage U1 is determined at a first time t1 and a second capacitor voltage U2 is determined at a second time t2 subsequent to time t1. A test current is drawn between time t1 and time t2. t1 is determined by the beginning of drawing the test current and time t2 is determined such that the capacitor voltage at time t2 is in a steady state and is substantially constant while the test current is being drawn. A charging state of the battery is determined from the difference in voltage between U1 and U2 and/or from a time difference between the time t1 and time t2.

  • Patent number: 10252003
    Abstract: Embodiments disclosed herein include systems and methods for administering a drug over a time period. One embodiment of a system includes an administration unit, a housing that houses the administration unit, and a controller unit adapted to receive an alarm triggering signal. Also included in some embodiments is an alarming unit that is adapted to generate an alarm signal on reception of the alarm triggering signal. Some embodiments include a patient state monitor that includes a motion-sensitive sensor unit that is reactive on patient motion. The patient state monitor may be adapted to process a sensor signal generated by the motion-sensitive sensor unit. The patient state monitor may also be adapted to transmit the alarm triggering signal to the controller unit if a patient motion level is below a predefined motion level, as determined by a length of time without patient motion.
