Patent number: 11890090Abstract: An example breath collection and sampling device disclosed herein comprises a cartridge housing having a breath capture module, and a rotary valve operatively coupling a mouthpiece with the breath capture module. The rotary valve can have an open position where breath of a user can pass through the rotary valve, across capture sites of the breath capture module, and into a vacuum port, and a closed position for sealing the breath capture module from fluid passing through the rotary valve, while allowing the breath capture module to be exposed to a reagent for subsequent analysis of contents within the captured breath.Type: GrantFiled: August 25, 2022Date of Patent: February 6, 2024Assignee: Hound Labs, Inc.Inventors: Michael Scott Lynn, Joseph A. Heanue, Kevin M. Limtao, Jeffrey A. Schuster, Peter A. Holst

Patent number: 10960399Abstract: Cartridge-based thermocyclers can include cartridges that are configured to move a fluid between distinct chambers. In some cases, the cartridge-based thermocyclers can be used for thermocycling a sample fluid comprising a deoxyribonucleic acid (DNA) target to perform polymerase chain reaction (PCR). Individual chambers can be heated, cooled, and/or compressed to mix fluid within the chamber or to propel fluid in the chamber into another chamber. The cartridges can have a laminate construction. The cartridges can be configured to enable multiplexed thermocycling and/or detection.Type: GrantFiled: December 20, 2018Date of Patent: March 30, 2021Assignee: Visby Medical, Inc.Inventors: Hamilton R. Tang, Adam De La Zerda, Kenneth I. Li, Kevin M. Limtao, Alan D. Baldwin, Gregory C. Loney

Publication number: 20200245898Abstract: The present disclosure describes a single-use microfluidic cartridge that is can be utilized with a portable and handheld breath collection and analysis device to detect a presence of a target chemical in human breath. The cartridge receives an air sample of human breath, processes it to extract the target chemical in solution, and reacts the solution with chemical reagent(s) to determine a concentration level of the target chemical present in the collected breath sample. Additionally, a portion of the collected sample can be contained in a separate reservoir of the cartridge of evidence preservation. The cartridge may further contain a cryptographic computing chip to store information regarding the sample processed within the cartridge.Type: ApplicationFiled: May 29, 2019Publication date: August 6, 2020Inventors: Joseph A. Heanue, Jeffrey A. Stoll, Samartha G. Anekal, Kevin M. Limtao, Kevin Bradford Dunk, Jeffrey A. Schuster

Publication number: 20200245899Abstract: The present disclosure describes systems, methods, and apparatus for a portable and handheld mechanical breath collection device. The mechanical breath collection device collects air from a human subject, filters out saliva from the human subject, and collects aerosolized droplets from the received air via inertial impaction on an impactor surface. A target chemical is then extracted from the collected aerosolized droplets, and analyzed. In this way, a concentration of a target chemical present from the human subject can be determined by the portable and handheld device.Type: ApplicationFiled: May 29, 2019Publication date: August 6, 2020Inventors: Joseph A. Heanue, Jeffrey A. Stoll, Samartha G. Anekal, Kevin M. Limtao, Kevin Bradford Dunk, Jeffrey A. Schuster
