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: 20200352493Abstract: Disclosed is an apparatus for analyzing the composition of bodily fluid. The apparatus can include a fluid handling network including a patient end configured to maintain fluid communication with a bodily fluid in a patient and a pump unit in operative engagement with the fluid handling network. The pump unit can have an infusion mode, in which the pump unit is operable to deliver infusion fluid to the patient through the patient end, and a sample draw mode, in which the pump unit is operable to draw a sample of the bodily fluid from the patient through the patient end. The apparatus can include a spectroscopic analyzer positioned to analyze at least a portion of the sample; a processor in communication with or incorporated into the spectroscopic analyzer; and stored program instructions executable by the processor to obtain measurements of two or more properties of the sample.Type: ApplicationFiled: February 12, 2020Publication date: November 12, 2020Inventors: Jennifer H. Gable, James R. Braig, Kenneth I. Li, Mark Wechsler, Peng Zheng, Richard Keenan

Publication number: 20200352494Abstract: A fluid handling module that is removably engageable with a bodily fluid analyzer is provided. The module may comprise a fluid handling element, and a fluid component separator that is accessible via the fluid handling element and configured to separate at least one component of a bodily fluid transported to the fluid component separator. The fluid handling element may have at least one control element interface.Type: ApplicationFiled: February 21, 2020Publication date: November 12, 2020Inventors: Jennifer H. Gable, James R. Braig, Kenneth I. Li, Mark Wechsler, Peng Zheng, Richard Keenan

Publication number: 20200187839Abstract: A reagentless whole-blood analyte detection system that is capable of being deployed near a patient has a source capable of emitting a beam of radiation that includes a spectral band. The whole-blood system also has a detector in an optical path of the beam. The whole-blood system also has a housing that is configured to house the source and the detector. The whole-blood system also has a sample element that is situated in the optical path of the beam. The sample element has a sample cell and a sample cell wall that does not eliminate transmittance of the beam of radiation in the spectral band.Type: ApplicationFiled: December 9, 2019Publication date: June 18, 2020Inventors: James R. Braig, Peter Rule, Philip C. Hartstein, Bernhard B. Sterling, Jennifer H. Gable, Kenneth I. Li
