Publication number: 20190151537Abstract: Apparatus are provided for infusion devices and related control systems and methods. In one embodiment, an infusion device includes a voided portion adapted to receive a shaft portion that includes a shaft coupled to a plunger of a reservoir. The shaft portion includes a detectable feature, and the infusion device includes a sensing arrangement proximate the voided portion to sense the detectable feature. In some embodiments, a control module is coupled to the sensing arrangement to determine a remaining amount of fluid in the reservoir based at least in part on the sensed position of the detectable feature. In other embodiments, the control module identifies an anomalous condition based at least in part on the sensed position of the detectable feature.Type: ApplicationFiled: January 23, 2019Publication date: May 23, 2019Inventors: Afshin BAZARGAN, Pablo VAZQUEZ, EJMar FONACIER, Andrew E.

Patent number: 9682188Abstract: Apparatus are provided for infusion devices and related control systems and methods. In one embodiment, an infusion device includes a voided portion adapted to receive a shaft portion that includes a shaft coupled to a plunger of a reservoir. The shaft portion includes a detectable feature having an optically detectable pattern such as gray code, and the infusion device includes a sensing arrangement having an optical sensor proximate the voided portion to sense the detectable feature. In some embodiments, a control module is coupled to the sensing arrangement to determine a remaining amount of fluid in the reservoir based at least in part on the sensed position of the detectable feature. In embodiments, the optical sensor detects the sensed position of the shaft based on the detectable feature only when the reservoir is replaced and/or after each delivery of fluid to reduce power consumption.Type: GrantFiled: November 26, 2013Date of Patent: June 20, 2017Assignee: MEDTRONIC MINIMED, INC.Inventors: Bozhil Makaveev, Yongbo Wang, Ben Wu, Afshin Bazargan, Pablo Vazquez, EJMar Fonacier, Andrew E.

Patent number: 8841012Abstract: A device for delivering fluid to a user includes a housing, a drive motor assembly in the housing, other internal components in the housing, and a keypad external to the housing. The device includes a number of features and elements that enhance its operation, manufacturability, reliability, and user-friendliness. These features and elements include a shock absorbing element for a battery of the device, a keypad actuator layer that overlies a keypad assembly and forms a water resistant seal with the housing, and an offset element for a piezoelectric speaker that is located inside the housing.Type: GrantFiled: September 12, 2013Date of Patent: September 23, 2014Assignee: Medtronic MiniMed, Inc.Inventors: EJMar Fonacier, Kirk A. Allen, Chad Srisathapat, Afshin Bazargan
