Patent number: 11154853Abstract: An assay is performed so as to identify a pathogen in a sample taken from a patient. The identity of the pathogen in the patient sample is used to select an antimicrobial for treatment of the patient. The antimicrobial can be selected in less than 7 hours after the patient sample is taken from the patient. For instance, when the sample is blood, the antimicrobial can be selected in less than 7 hours after the patient sample is taken from the patient. When the sample is urine, the antimicrobial can be selected in less than 4 hours after the patient sample is taken from the patient.Type: GrantFiled: December 21, 2018Date of Patent: October 26, 2021Assignee: GeneFluidics, Inc.Inventors: Jen-Jr Gau, Michael Tomasek

Publication number: 20200056220Abstract: A method of data collection includes culturing a sample that was generated from a raw sample. The raw sample was taken from a patient and the sample includes a pathogen when the raw sample included the pathogen. An assay sample is generated from a portion of the sample such that the assay sample includes the pathogen when the sample included the pathogen. The sample is cultured for a time period that less than hours and greater than or equal to 0.0 hours before the portion of the test sample was taken from the test sample. The assay sample is assayed so as to determine whether the pathogen is present in the assay sample.Type: ApplicationFiled: August 16, 2019Publication date: February 20, 2020Inventors: Jen-Jr Gau, Michael Tomasek

Patent number: 9784738Abstract: A device includes multiple components that are independent from one another but are configured to be detachably coupled with one another so as to form a cartridge. One of the components is a clamp that is configured to hold the other components such that they are coupled together.

Patent number: 9274081Abstract: Performing an electrokinetic treatment on different samples includes identifying an electrical signal that is appropriate for use in the treatment of each sample. The identification of the electrical signals results in different electrical signals being identified for different samples. The electrokinetic treatment of a sample results in that sample being exposed to the electrical signal identified for that sample. Accordingly, different samples are exposed to different electrical signals. An electrokinetic treatment employs one or more electrokinetic phenomena to cause movement of one or more agents within the sample relative to the sample. In some instances, the method also includes using each of the electrokinetically treated samples to generate an electrochemical sample and then performing an electrochemical analysis on each of the electrochemical samples.Type: GrantFiled: July 8, 2013Date of Patent: March 1, 2016Assignee: GeneFluidics, Inc.Inventor: Jen-Jr Gau
