Patent ID: 10598675

Abstract:
The present invention relates to analytical testing devices comprising a single channel with micro-environment sensors and methods for assaying coagulation in a fluid sample applied to the micro-environment sensors, and in particular, to performing coagulation assays using a single channel with micro-environment sensors in a point of care test cartridge. For example, the present invention may be directed to a sample analysis cartridge including an inlet chamber configured to receive a biological sample and a conduit fluidically connected to the inlet chamber. The conduit includes a sensor chip including a first micro-environment sensor and a second microenvironment sensor, and a fluid lock valve. The sample analysis cartridge further includes a pump configured to push the biological sample over the first micro-environment sensor and the second microenvironment sensor to the fluidic lock valve such that the biological sample is positioned over the first micro-environment sensor and the second micro-environment sensor.
