Patent number: 10004444Abstract: The application relates to a collection assembly (1), in particular for blood samples, comprising a sample container (2) and a closure device (3) which has a closure cap (22) and a pierceable septum (26) held on the closure cap. At its open end (4) delimited by an end face (11), the sample container has a flange (13) and an annular skirt (15), the flange projecting radially beyond a side wall (7). The annular skirt (15) extends axially from a flange end (14) to a closed end (5) of the sample container (2). The sample container (2), the flange (13) and the annular skirt form a one-piece component. Between an outer surface (9) of the side wall (7) and an inner annular skirt surface (16) facing toward this outer surface, there is an approximately tubular free space (17) which is delimited in the axial direction in the region of the open end (4) by the flange (13).Type: GrantFiled: October 9, 2014Date of Patent: June 26, 2018Assignee: Greiner Bio-One GmbHInventors: Christian Bauer, Georg Kofler

Patent number: 10000790Abstract: The subject invention provides materials and methods for detecting the presence of an electron donor. In a specific embodiment, the device detects the presence of dihydronicotinamide adenine dinucleotide (NADH) via a colorimetric change output by the sensing device. In another specific embodiment, the presence of an enzyme capable of catalyzing, or an agent capable of inhibiting, the production of NADH can also be detected by a colorimetric readout using the same device. In some embodiments, dihydronicotinamide adenine dinucleotide phosphate (NADPH) can also be detected using the device provided herein. Advantageously, preferred embodiments of the subject invention provide a low-cost, sensitive device for monitoring the presence of critical biological analytes in a variety of applications.Type: GrantFiled: June 28, 2015Date of Patent: June 19, 2018Assignee: THE FLORIDA INTERNATIONAL UNIVERSITY BOARD OF TRUSTEESInventors: Pingping Liang, Haixiang Yu, Yi Xiao

Patent number: 9962704Abstract: A specimen collection container includes inner and outer tubes. The inner tube includes a bottom end, a top end, and a sidewall extending therebetween defining an interior. The sidewall includes an inner surface and an outer surface having at least one annular protrusion extending therefrom. The inner tube includes at least one funnel portion adjacent the top end for directing a specimen into the inner tube interior, and an annular ring disposed about a portion of the outer surface of the sidewall adjacent the top end. The outer tube includes a bottom end, a top end, and a sidewall extending therebetween, the sidewall having an outer surface and an inner surface defining an annular recess adapted to receive a portion of the annular protrusion therein. The inner tube is disposed within the outer tube and a portion of the top end of the outer tube abuts the annular ring.Type: GrantFiled: June 15, 2016Date of Patent: May 8, 2018Assignee: Becton, Dickinson and CompanyInventors: Benjamin R. Bartfeld, Robert G. Ellis, Robert S. Golabek, Jr., Nancy Dubrowny, Girish Parmar, Paul Holmes, Alex Blekher, Michael Delk

Patent number: 9963273Abstract: A film bag for storing a fluid, in particular a reagent or an auxiliary agent for a biochemical analysis method, includes a film, a seam, and an irreversibly destructible predetermined breaking point. The film is impermeable to the fluid and constituents of the fluid. The seam is formed in a fluid-tight manner between a first sub-region of the film and a second sub-region of the film and forms the film into a fluid-tight bag for accommodating the fluid. The bag is configured to be arranged in a chamber of a device that provides a fluid for a biochemical evaluating unit. The predetermined breaking point is formed from the film and is fluid-tight when a fluid pressure in the film bag is below a limit. The predetermined breaking point is destroyed when the fluid pressure is above the limit.Type: GrantFiled: December 2, 2013Date of Patent: May 8, 2018Assignee: Robert Bosch GmbHInventors: Michael Hortig, Yvonne Beyl, Daniel Czurratis, Sven Zinober, Lars Sodan, Martina Daub, Jochen Rupp, Holger Behrens

Patent number: 9939401Abstract: An improved disposable electrochemical test sensor designed to facilitate sampling of fluid samples. It has a fluid chamber having a novel extra wide sampling entrance. The chamber provides a reservoir from which a sample fluid can be drawn into the chamber through capillary action. The novel extra wide sampling entrance of the test sensor provided by the present invention can draw blood into the chamber not only from the front of the sampling entrance as usual in convenient sensors, but also from the top, bottom, left corner and right corner of the sampling entrance. Thus it allows easy targeting the samples with small volume, picking up smeared samples and it is more tolerant to users who jam the tip of the sensor into users' finger.Type: GrantFiled: February 20, 2014Date of Patent: April 10, 2018Assignee: Changsha Sinocare Inc.Inventors: Xiaohua Cai, Hongli Che, Shaobo Li
