Patent number: 10533986Abstract: Methods and systems for measuring and using the oxidation-reduction potential (ORP) of a biological sample are provided. The system generally includes a test strip and a readout device for determining the ORP. The measured ORP is then used to determine characteristics relating to the fertility of the sample or the subject from which the sample was derived. Some characteristics that can be determined include the quality of a sperm sample, an oocyte or a fertilized egg. The measured ORP value can also be used to determine the specific characteristics of a spermatozoa sample, such as the morphology of the spermatozoa, the motility of the spermatozoa, the number of cells in the sample and the concentration of the cells in the sample. Knowledge of such characteristics and fertility potential can be used to identify individuals that might benefit from specific fertility treatments.Type: GrantFiled: August 24, 2018Date of Patent: January 14, 2020Assignee: Aytu BioScience, Inc.Inventors: Raphael Bar-Or, David Bar-Or, Leonard T. Rael, Kimberly B. Bjugstad, Ashok Agarwal, Rakesh Sharma, Sajal Gupta

Patent number: 10281425Abstract: A multiple layer gel and method for forming a multiple layer gel are provided. The multiple layer gel includes an isolation layer and an electrolyte layer. The isolation layer provides a molecular weight screen, to prevent proteins or other molecules from contacting a reference cell covered by the isolation layer. The electrolyte layer covers the isolation layer, and provides a source of ions that place the reference cell in ionic and/or electrical contact with a fluid sample. The multiple layer gel can be used to maintain a reliable reference voltage from an associated reference cell while an electrical potential or other electrical characteristic of a sample fluid is being determined.Type: GrantFiled: May 18, 2016Date of Patent: May 7, 2019Assignee: Aytu BioScience, Inc.Inventors: Raphael Bar-Or, David Bar-Or, Leonard T.

Methods and systems for measuring and using the oxidation-reduction potential of a biological sample
Patent number: 10184931Abstract: Methods and systems for measuring and using the oxidation-reduction characteristics of a biological sample are provided. The system generally includes a test strip and a readout device. A fluid sample is placed in the test strip, and the test strip is in turn operatively connected to the readout device. The readout device provides a controlled current that is sent across the fluid in the sample chamber. In addition, the readout device identifies an inflection point or transition time at which the voltage between contacts of the test strip is changing at the highest rate. The oxidation-reduction capacity of the sample is taken as the integral of the current profile from the time at which current begins to be supplied to the sample to the identified transition time.Type: GrantFiled: May 5, 2016Date of Patent: January 22, 2019Assignee: Aytu BioScience, Inc.Inventors: Raphael Bar-Or, David Bar-Or, Leonard T.

Patent number: 10036723Abstract: The present invention provides a method of determining the overall oxidative status of a body fluid or a tissue of a patient by measuring the oxidation-reduction potential (ORP) of the body fluid or tissue. The method has been found to be useful in the diagnosis, evaluation and monitoring of patients who have suffered a trauma (such as a head injury), patients suspected of being critically-ill or who are critically ill, patients who have an infection, and patients suspected of having a myocardial infarction (MI) or who have had an MI. The method has also been found useful in monitoring and evaluating exercise performance in patients. In addition, the method has been found useful in monitoring and evaluating stored blood products and patients who will receive such a product.Type: GrantFiled: June 17, 2016Date of Patent: July 31, 2018Assignee: AYTU BIOSCIENCE, INC.Inventors: David Bar-Or, Raphael Bar-Or

Patent number: 9528959Abstract: Methods and systems for measuring the oxidation-reduction potential of a fluid sample are provided. The system includes a test strip with a sample chamber adapted to receive a fluid sample. The sample chamber can be associated with a filter membrane. The test strip also includes a reference cell. The oxidation-reduction potential of a fluid sample placed in the sample chamber can be read by a readout device interconnected to a test lead that is in electrical contact with the sample chamber, and a reference lead that is in electrical contact with the reference cell. Electrical contact between a fluid sample placed in the sample chamber and the reference cell can be established by a bridge. The bridge may comprise filter element such as a piece of filter paper that is wetted, for example by the fluid sample, or an electrolytic gel. The oxidation-reduction potential may be read as an electrical potential between the test lead and the reference lead of the test strip.Type: GrantFiled: April 13, 2015Date of Patent: December 27, 2016Assignee: AYTU BIOSCIENCE, INC.Inventors: Raphael Bar-Or, David Bar-Or, Leonard T.
