Patent number: 9895490Abstract: A device for delivering fluid to a user includes a housing, a drive motor assembly in the housing, a force sensor, and an electronics module. The drive motor assembly regulates delivery of fluid by actuating a piston of a fluid reservoir, and the force sensor generates output levels in response to force imparted thereto during, for example, fluid delivery operations. The electronics module processes the output levels of the force sensor to assess the operating health of the force sensor, to check for occlusions in the fluid delivery path, and to monitor the seating status of the fluid reservoir.Type: GrantFiled: May 7, 2015Date of Patent: February 20, 2018Assignee: Medtronic MiniMed, Inc.Inventors: Hsiao-Yu S. Kow, Afshin Bazargan, Ian B. Hanson, Pablo Vazquez, Juan M. Alderete, Jr., Salman Monirabbasi

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.

Publication number: 20160367751Abstract: An embodiment of a fluid infusion device includes a fluid pump mechanism having a rotor and a stator. The rotor includes a reference surface and a cam element rising from the reference surface, and the stator includes a cam element having a stator cam surface. The cam elements cooperate to axially displace the rotor as a function of angular position of the rotor. A biasing element provides force to urge the cam elements together. A drive motor actuates the rotor to pump medication fluid from a fluid cartridge module to a body, via a subcutaneous conduit. A detection circuit processes axial and angular position data of the rotor, and determines that an upstream occlusion has occurred based on detectable characteristics of the axial and angular position data.Type: ApplicationFiled: June 22, 2015Publication date: December 22, 2016Inventors: Afshin Bazargan, Juan M.
