  • Publication number: 20110279123
    Abstract: Included are embodiments of an ambulatory infusion device. Some embodiments include an energy storage for storing electrical energy utilized for powering the ambulatory infusion device. The energy storage may serve as a primary power source of the ambulatory infusion device. Also included is a dosing unit with an electrically powered actuator and an electronic controller, where the electronic controller controls operation of the electrically powered actuator. Some embodiments also include a testing unit for testing the energy storage. The testing unit may be configured to repeatedly carry out a test during operation of the ambulatory infusion device. Additionally, the test may include determining a control variable, the control variable being indicative of a capability of the energy storage for further powering the ambulatory infusion device.

  • Publication number: 20110160665
    Abstract: Included are embodiments of an ambulatory infusion device. Some embodiments include a battery receiving portion that receives a user-replaceable battery of variable individual characteristics. The user-replaceable battery may serve as a primary power source of the ambulatory infusion device and being successively depleted during application. Similarly, some embodiments include a dosing unit with an electrically powered actuator and an electronic controller that controls operation of the ambulatory infusion device. Still some embodiments include a testing unit that is operatively coupled to the electronic controller, the testing unit being designed to carry out a battery test, the battery test including determining an off-circuit voltage and an internal resistance of the user-replaceable battery. Still some embodiments include an alerting unit that is operatively coupled to the testing unit and/or the electronic controller to provide an alert to a device user in dependence of a battery test result.

  • Publication number: 20110060281
    Abstract: A medical infusion pump and a method for logging a power source voltage of a medical infusion pump are disclosed. The medical pump may include a power source, a processor, and a voltage supervisor which responds if a voltage (VDD) drops to a response voltage level which is above a reset voltage level of the processor. When the voltage supervisor responds, the processor start logging the voltage (Vbat) of the power source in a memory, thus generating a voltage log. The memory maintains the logged data when the power supply by the power source is interrupted, thus enabling retrospective analysis of the voltage log.

  • Publication number: 20090299296
    Abstract: A container for receiving liquids with different concentrations of an active substance that is to be administered or dosed, wherein the container includes a hollow body and a displaceable element for expelling the liquid is located for longitudinal movement in the hollow body, and wherein the cross-sectional surface area of the hollow body is inversely proportional to the concentration of the substance, such that, with identical strokes or longitudinal movements of the displaceable element, the discharged amount of active substance remains independent of the concentration of the substance in the container.
