  • ROTATIONAL METERING PUMP FOR INSULIN PATCH
    Publication number: 20200360601
    Abstract: A rotary pump for a fluid metering system is provided. The rotary pump reciprocates, and is reversed by a signal from a limit switch that is deflected by an actuator arm on a rotating sleeve of the pump system. The rotary pump includes a plunger and optional stopper formed from a two-shot molding process, and including seals overmolded onto the head of the plunger and the head of the optional stopper.
    Type: Application
    Filed: August 5, 2020
    Publication date: November 19, 2020
    Applicant: Becton, Dickinson and Company
    Inventors: Alessandro E. Pizzochero, Richard Gyory, Kenneth Focht, Justin Fisk, Joe Gordon, Matthew Perry, Ajit D'Souza, Chris Petroff

  • Rotational metering pump for insulin patch
    Patent number: 10132308
    Abstract: Metering systems and methods are disclosed. A metering system is part of a larger fluidics sub-system that includes a flexible reservoir for storing insulin and a cannula assembly for delivering the insulin into sub-cutaneous tissue. The metering system draws a small dose of fluid from the reservoir and then pushes it down the cannula line and into the patient. The fluid dose is small relative to the reservoir volume, such that many pump strokes are required to completely empty the reservoir.
