Publication number: 20240024568Abstract: 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: October 2, 2023Publication date: January 25, 2024Applicant: Becton, Dickinson and CompanyInventors: Kenneth Focht, Joseph Gordon, Matthew J. Perry, Justin Fisk

Patent number: 9782323Abstract: A compression treatment system is provided that detects the number of and type of garments connected thereto. The system includes a plurality of ports, valves connected thereto and a number of garments having one or more bladders. The bladders are in fluid communication with a fluid source in a pneumatic circuit, to provide compression therapy once a user confirms the number of and type of garments connected to the system for use by a patient. A single pressure sensor communicates with a plurality of detected bladders located in the one or more garments.Type: GrantFiled: March 17, 2014Date of Patent: October 10, 2017Assignee: COVIDIEN LPInventors: Matthew J. Perry, Mark A. Vess, Scott Wudyka

Patent number: 4678331Abstract: An improved analytical cuvette rotor assembly for use in a centrifugal chemistry analyzer comprising a disc-shaped body having a plurality of radially extending compartments for retaining fluids. Sample fluids and reagent fluids contained in the compartments prior to centrifugation are separated by a novel dam structure extending between upper and lower surfaces of each compartment such that the premature mixing of sample and reagent fluid is significantly retarded. The dam, in cooperation with the compartment walls, further defines a fluid transfer passage that permits fluids to be transferred over the dam under analyzer operating rotational speeds.Type: GrantFiled: June 21, 1984Date of Patent: July 7, 1987Assignee: Baxter Travenol Laboratories, Inc.Inventor: Matthew J.
