Point of care test cartridge

A test cartridge for evaluating biological fluids can have a sensor flow cell defining a flow path for selectively passing a test fluid or biological fluid across a sensor to evaluate the sensor or the biological fluid. The test cartridge can include a sample port and at least one deformable reservoir, both formed as part of the test cartridge and fluidly connected to the flow path upstream of the sensor. A biological fluid can be manually fed into the flow path through the sample port for evaluation by the sensor. Before the biological fluid is fed through the sample port, the deformable reservoir can be manually ruptured to pass the test fluid contained within the reservoir across the sensor to first evaluate the sensor. In an example, the deformable reservoir can include a first reservoir containing a liquid quality control (LQC) fluid and a second reservoir containing a calibration fluid.

OPTOFLUIDIC DIAGNOSTICS SYSTEM
20220042919 · 2022-02-10 ·

An optofluidic diagnostic system and methods for rapid analyte detections. The system comprises an optofluidic sensor array, a test plate and an optical detection cartridge. The sensor array supports one or more distinct sensor units, each having a reactor section designed to temporarily enter a series of different kinds of wells in the test plate. One kind of well is a sample reservoir that holds reagent solution to be transferred into the reactor section. Another kind of well is a drainage chamber that removes reagent solution from the reactor section. A third kind of well is a colorant reservoir that holds a colorant reagent transferable into a reactor section. Finally, the sensor unit is transferred to the optical detection cartridge where it is placed into an isolation booth during the optical detection process so that its flat observation face is stationed in a viewing window opposite an optical detector lens.
