Patent number: 11602596Abstract: The safety and reliability of drug delivery systems are improved by the use of smartphones for calculating safety critical delivery parameters. A drug delivery device is adapted to perform a drug delivery operation based on an unconfirmed drug delivery instructions determined by a processing unit of a control device by applying a basic mathematic operation to control device input data. The drug delivery device comprises a communication module to receive, from the control device, the basic mathematic operation and the control device input data, and a redundancy module to determine a redundant drug delivery instructions by applying the basic mathematic operation to the control device input data received from the control device. The drug delivery device is adapted to prevent execution of the drug delivery operation if the unconfirmed drug delivery instructions and the redundant drug delivery instructions are found, by a comparator module, to conflict.Type: GrantFiled: April 29, 2020Date of Patent: March 14, 2023Assignee: Ypsomed AGInventors: Bernhard Rytz, Michael Rufer, Stefan Lindegger

Patent number: 10251583Abstract: A device and method for delivering insulin to a patient is disclosed. The method includes receiving an amount of insulin to deliver to a patient and beginning delivery of the insulin to the patient. The method further includes monitoring the delivery of the insulin to determine whether the insulin pump is able to deliver the entire amount of insulin and maintaining a timer until the insulin pump recommences the delivery of the insulin.

Patent number: 9377513Abstract: An ambulatory infusion device comprising a replaceable energy storage for electrically powering its functional units is presented. Control units provide to a monitoring system data about energy consuming activities or consumed energy by the functional units. Based on this data, the monitoring system determines energy consumed by the functional units and triggers measurement of the voltage of the energy storage at a point in time which depends on the determined energy consumed in a time interval preceding the point in time. Adapting the time of measurement to the actual energy drawn from the energy storage makes it possible to detect reliably and early a low energy state of any conventional standard battery, regardless of its electrochemical design and electrical behavior.Type: GrantFiled: February 7, 2013Date of Patent: June 28, 2016Assignee: Roche Diagnostics International AGInventor: Stefan Lindegger
