TY - PAT T1 - United States Patent: 8980635 - Disposable cartridge for fluid analysis Y1 - 2015 A1 - Kelley, Mark A1 - Bardell, Ron A1 - Janisch, Robert A1 - Wong, Pamela A1 - Peltola, Eric AB - A disposable blood analysis cartridge may include a sample collection reservoir, an absorbance measurement channel, and an optical light scattering measurement channel. One or more valves may be disposed between the sample collection reservoir and the absorbance measurement channel and/or the optical light scattering measurement channel. A negative pressure may be applied to the cartridge to pull sample from the sample collection reservoir through the one or more valves and into the absorbance measurement channel and/or the optical light scattering measurement channel. Once the sample is pulled into the absorbance measurement channel and/or the optical light scattering measurement channel, the one or more valves may be closed. With the one or more valves closed, and in some cases, a pusher fluid may be provided to push the fluid sample to other regions of the disposable fluid blood analysis cartridge.

In use, processed sample may be introduced into a sheath fluid channel at an angle, .alpha., of approximately 90 degrees, relative to the direction of flow of the sheath fluid. In addition, delivering the sample from the side into the sheath fluid may facilitate better positioning of the core within the hydrodynamic focusing channel for measurement.

The optical absorbance measurement channel includes a plasma separation region and at least one sub channel including a cuvette that is in fluid communication with the plasma separation region and configured to receive a plasma portion of a blood sample that has been passed through the plasma separation region. A negative pressure may be applied to the cartridge to draw the sample through the plasma separation region and into the sub channel including the cuvette.

First, capillary action may be used to initially draw a sample through a sample introduction port and into a sample collection reservoir provided in the fluid analysis cartridge. Once the fluid sample has been drawn into the sample collection reservoir by capillary action, a negative pressure may be applied to the cartridge to pull the sample from the sample collection reservoir and into a sample loading channel. A valve may be disposed between the sample collection reservoir and the sample loading channel to prevent backflow of sample into the sample collection reservoir and to retain sample in the sample loading channel.
