AMBULATORY INFUSION DEVICE WITH VARIABLE ENERGY STORAGE TESTING AND METHOD FOR TESTING AN ENERGY STORAGE
First Claim
1. Ambulatory infusion device which administers a drug or substance to a patient, comprising:
- an energy storage which depletes; and
a testing unit for testing the energy storage, the testing unit configured to repeatedly carry out a test during operation of the ambulatory infusion device, the test including determining a control variable, the control variable being indicative of a capability of the energy storage to further power the ambulatory infusion device, wherein the testing unit is configured to vary the testing of the energy storage in dependence of the control variable.

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.

12. A method for testing a depleting electrical energy storage powering an ambulatory infusion device, the method comprising:
-
repeatedly carrying out tests during operation of the ambulatory infusion device via a testing unit of the ambulatory device, at least one of the tests including a determination of a control variable, the control variable being indicative of a capability of the depleting electrical energy storage for further powering the ambulatory infusion device; varying, via the testing unit, the testing in dependence of the control variable, in which the testing unit reduces the testing interval for carrying out consecutive tests upon a change of the control variable that indicates a decreasing capability of the electrical energy storage for further powering the ambulatory infusion device; and triggering, via the testing unit, an alert upon a test indicating a lack of capability of the electrical energy storage for further powering the ambulatory infusion device. - View Dependent Claims (13, 14, 15, 16)
