Publication number: 20230218820Abstract: An infusion apparatus includes a housing and a chamber configured to be connected to the housing. The apparatus further includes a weight sensor coupled to a load connector connected to the housing and an optical sensor disposed in the housing. The weight sensor is configured to generate a first signal based on a measured weight of the fluid container attached to the housing in a weight-bearing configuration. The optical sensor is configured to generate a second signal based on detecting drops of the fluid traversing the chamber. The apparatus also includes a flow control mechanism to control a flow rate of the fluid into an outlet channel. The apparatus includes one or more processing devices configured to perform operations including transmitting a control signal to the flow control mechanism to adjust the flow rate.Type: ApplicationFiled: February 24, 2023Publication date: July 13, 2023Inventors: Nathaniel M. Sims, Eric John Flachbart, Duane Edward Allen, Benjamin James Chomyn, Paul C. Henninge, Joseph Matthew Pasquence, Andrew W. Asack, Michael H. Wollowitz, Rolf E. Zuk

Publication number: 20170326293Abstract: An infusion apparatus for use with a syringe includes a housing enclosing a drivetrain. The drivetrain includes a pinion, spur gears, and a worm gear. One spur gear is arranged to engage with the pinion and another spur gear is arranged to engage with the worm gear. The housing also includes a carriage movable with respect to the housing. A frame on the carriage receives a syringe plunger. A rack on the carriage engages with the pinion to move the carriage parallel to a longitudinal axis of the housing. A pusher assembly of the housing securely engages with the syringe plunger. A motor in the apparatus rotates a worm drive that meshes with the worm gear to drive the drivetrain. A trigger of the apparatus is configured to disengage the worm drive from the worm gear to allow free movement of the carriage relative to the housing.Type: ApplicationFiled: November 12, 2015Publication date: November 16, 2017Inventors: Nathaniel M. Sims, Eric John Flachbart, Duane Edward Allen, Benjamin James Chomyn, Paul C. Henninge, Joseph Matthew Pasquence, Andrew W. Asack, Michael H. Wollowitz, Rolf E. Zuk
