Patent number: 11771827Abstract: 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.Type: GrantFiled: February 17, 2020Date of Patent: October 3, 2023Assignee: Roche Diabetes Care, Inc.Inventor: Kurt Friedli

Patent number: 11686774Abstract: 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.Type: GrantFiled: January 21, 2020Date of Patent: June 27, 2023Assignee: Roche Diabetes Care, Inc.Inventors: Kurt Friedli, Christian Wuertele, Christian-Alexander Luszick

Patent number: 11488710Abstract: 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.Type: GrantFiled: May 15, 2020Date of Patent: November 1, 2022Assignee: Roche Diabetes Care, Inc.Inventors: Kurt Friedli, Michael Mueller, Nils Danckwardt
