Patent number: 11867635Abstract: A method for performing a diagnostic test comprises generating a first visual trigger on a display screen of a mobile device responsive to activation of an application on the mobile device. An image of a diagnostic test presently viewed by a camera incorporated with the mobile device is displayed on the display screen of the mobile device. The diagnostic test has a second visual trigger thereon. The image and the first visual trigger are displayed on the display screen at a same time. An image is captured by the application of the diagnostic test responsive to alignment of the first visual trigger with the second visual trigger on the display screen of the mobile device. The captured image is processed to provide test results for the diagnostic test.Type: GrantFiled: December 4, 2020Date of Patent: January 9, 2024Assignee: Reliant Immune Diagnostics, Inc.Inventors: Jovan Hutton Pulitzer, Henry Joseph Legere, III

Patent number: 11866763Abstract: An improved system, method and interface for automated rapid antimicrobial susceptibility testing (AST) is disclosed which includes, in one aspect, a carrier population station comprising a workstation having a graphic user interface (GUI). The GUI accepts information from a lab technologist, including information related to a scope of testing to be performed on a patient sample. The GUI controls intelligent assignment of patient samples to test panels in a manner that maximize utilization of the test carrier by grouping together samples of similar tests scopes and advantageously testing those samples using one multiplexed test panel. Customizing workflow in accordance with test scope to facilitate parallel processing of multiple samples advantageously reduces laboratory waste, decreases test latencies, increases AST system throughput and efficiency, and thus lowers the costs to the AST lab.Type: GrantFiled: November 14, 2019Date of Patent: January 9, 2024Assignee: SELUX DIAGNOSTICS, INC.Inventors: Kelly Flentie, Eric Stern

Patent number: 11859734Abstract: A microfluidic device has a first substrate, a resilient diaphragm, an actuator, and a second substrate. The first substrate has an opening extending therethrough. The resilient diaphragm is secured to a second side and surrounds the opening. The actuator is secured to a first side and surrounds the opening. The first substrate, the resilient diaphragm, and the actuator cooperate to form a gas-tight chamber. The second substrate has a channel formed therein having a first end and a second end. The second substrate is secured to the first substrate. A volume of gas disposed in the gas-tight chamber pressurizes the gas-tight chamber and expands the resilient diaphragm such that the resilient diaphragm is disposed in the channel between the first end and the second end. The resilient diaphragm retracts from the channel to open the channel from the first end and the second when the gas-tight chamber is depressurized.Type: GrantFiled: November 12, 2021Date of Patent: January 2, 2024Assignee: Siemens Healthcare Diagnostics Inc.Inventor: Aaron Kauffmann

Patent number: 11852642Abstract: A method of characterizing a serum or plasma portion of a specimen in a specimen container provides an HILN (hemolysis, icterus, lipemia, normal) determination. Pixel data of an input image of the specimen container is processed by a classification network to identify whether the specimen contains plasma or serum. Pixel data representing a plasma sample are forwarded to a segmentation/classification/regression network trained with plasma samples for HILN determination. Pixel data representing a serum sample are forwarded to a transformation network, wherein the serum sample pixel data is transformed into pixel data that matches pixel data of a corresponding previously-collected plasma sample by changing sample color, contrast, intensity, and/or brightness. The transformed serum sample pixel data are forwarded to the segmentation/classification/regression network for HILN determination. Quality check modules and testing apparatus configured to carry out the method are also described, as are other aspects.Type: GrantFiled: September 19, 2019Date of Patent: December 26, 2023Assignee: Siemens Healthcare Diagnostics Inc.Inventors: Venkatesh NarasimhaMurthy, Vivek Singh, Yao-Jen Chang, Benjamin S.
