Patent number: 10668226Abstract: A flow sensor is provided to enable volumetric dose data to be acquired automatically by sampling flow rates of insulin measured by a flow sensor exposed to a flow manifold though which the insulin flows. The flow sensor preferably connects to a standard insulin pen on one end, and to a standard pen needle on the other end. Particular geometries and algorithms are utilized to accommodate the unique requirements of insulin flow determination during an injection event.Type: GrantFiled: July 31, 2018Date of Patent: June 2, 2020Assignee: BECTON, DICKINSON AND COMPANYInventors: Gary Searle, Andrew Burke, Peter Costello, Kenneth Focht, Francis L.

Publication number: 20200078511Abstract: A micropump according to the invention uses axially oriented pistons to define a pump volume. Translating the pistons axially with respect to each other within a pump housing draws a metered amount of fluid into the pump volume from a reservoir port for delivery to a cannula port when the space is collapsed. Radially situated seals on the pistons cooperate with the axial movement to close off and open the cannula port and the reservoir port respectively at different positions of the piston stroke.Type: ApplicationFiled: November 15, 2019Publication date: March 12, 2020Applicant: Becton, Dickinson and CompanyInventors: Kenneth Focht, Joseph Gordon, Matthew J.

Patent number: 10132308Abstract: 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.Type: GrantFiled: April 6, 2015Date of Patent: November 20, 2018Assignee: Becton, Dickinson and CompanyInventors: Kenneth Focht, Justin Fisk, Joe Gordon, Matthew Perry, Ajit D'Souza, Chris Petroff

Patent number: 9867929Abstract: An infusion pump system is disclosed for dispensing liquid medication, such as insulin. The infusion pump system includes a first reservoir for storing liquid medication, a first fluid driver for exerting pressure on the first reservoir, a second reservoir for storing liquid medication, and a second fluid driver for exerting pressure on the second reservoir. One or more valves are used to permit flow of liquid medication from the first reservoir to the second reservoir, and to permit flow of liquid medication from the second reservoir to an infusion site. Each of the valves is selectively opened or closed to fill the second reservoir with liquid medication from the first reservoir and to dispense liquid medication from the second reservoir to the infusion site. A controller and one or more sensors are used to monitor and control the system.Type: GrantFiled: August 9, 2013Date of Patent: January 16, 2018Assignee: Becton, Dickinson and CompanyInventors: Gary Searle, Roman Tunkel, William Tormey, III, Andrew Leonczyk, David Pollock, Paul Naumann, Kenneth Focht

Publication number: 20170239415Abstract: A medical device for infusing medical substances has activation buttons accessible on the exterior of the device housing. Activation buttons and corresponding electrical switches within the housing are configured to prevent inadvertent activation of the buttons and therefore inadvertent operation of the switches to initiate a process such as medical substance delivery to the user. The device employs overlap of respective time traces initiated by activation of the activation buttons to determine whether activation is intended and valid. These time traces do not have to be initiated simultaneously or in any particular sequence. The activation buttons can be elastomeric overmolded buttons set within cutouts in the housing, and, when depressed, make physical contact with respective switches.Type: ApplicationFiled: September 9, 2015Publication date: August 24, 2017Inventors: Charles George HWANG, Richard J.
