Publication number: 20220031955Abstract: A method for enhancing data quality of a drug dose dispense data set to automatically provide dispense data reflecting actually injected dose amounts. For a given dispense session the method comprises the steps of creating a list of possible dispense patterns in accordance with a set of pattern rules and then for each pattern in the list calculate a weight allowing a winning pattern to be determined. Each dispense pattern is a particular sequence of priming events and injection events, with each dispense pattern being a possible interpretation of the dispense events in the current session. For each pattern a combined pattern weight being the product of weight factors for each dispense in the pattern is calculated, wherein each weight factor is determined in accordance with a weight factor vs dispense size function for the given dispense type and dispense size, wherein the larger the dispense size, the more likely it is to represent an injection event and the less likely it is to represent a priming event.Type: ApplicationFiled: September 24, 2019Publication date: February 3, 2022Inventors: Mark Haun, Carsten Schau Andersen, Thomas Dedenroth Miller, Ryan Scott Frazier

Publication number: 20170348486Abstract: A device for administering a fluid medicament by injection comprises a dosing portion (1) with a collapsible reservoir (10). The reservoir (10) has a maximum volume in an extended state and a minimum volume in a collapsed state. Prior to injection, the reservoir (10) is in the extended state and contains a liquid to be administered, and the reservoir (10) is biased towards the collapsed state. The device further comprises a needle (2), wherein a lumen (20) of the needle (2) is in fluid communication with the reservoir (10). The device further comprises a shield portion (3) with a plug (30). Prior to injection, the shield portion (3) is in a deployed position where the plug (30) blocks the lumen (20) of the needle (2). The shield portion (3) is adapted to move in response to an actuation force from the deployed position to a retracted position where the lumen (20) of the needle (2) is open, thereby causing the reservoir (10) to shift to the collapsed state to expel the liquid through the needle.Type: ApplicationFiled: December 22, 2015Publication date: December 7, 2017Inventors: Carsten Schau ANDERSEN, Simon RØRVIG, Steffen HANSEN
