Embodiment Construction

[0021] The following description should be read with reference to the accompanying drawings, wherein like reference numerals refer to like elements throughout the several views. The description and drawings illustrate several embodiments, which are intended to illustrate the claimed disclosure.

[0022] The present disclosure relates generally to disposable fluid cartridges for analyzing fluids, and more particularly to disposable fluid cartridges for analyzing a variety of biological fluids, including but not limited to blood, blood products (e.g., controls, , linearizers, calibrators, etc.), urine and / or other biological fluids of mammalian and non-mammalian origin. In some cases, the present disclosure can provide a sample analyzer that is easy to operate and reduces the risk of erroneous results. In some examples, the sample analyzer can be, for example, a hematology analyzer (such as a flow cytometer), a hematology analyzer, a clinical chemistry analyzer (such as a gluco...

Abstract

The present invention relates to a disposable cartridge for fluid analysis. 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.

Description

technical field [0001] The present disclosure relates generally to disposable fluid cartridges for analyzing fluids, and more particularly to disposable fluid cartridges for analyzing blood and / or other biological fluids. Background technique [0002] Chemical and / or biological analysis is important for life science research, clinical diagnostics, and a wide range of environmental and process monitoring. In some cases, sample analyzers are used to perform and / or assist in performing chemical and / or biological analyzes of sample fluids. Depending on the application, the sample fluid can be a liquid or a gas. [0003] Many sample analyzers are very large devices used by trained professionals in a laboratory setting. In order to use many sample analyzers, the collected sample must first be processed, such as diluting the sample to the desired level, adding appropriate reagents, centrifuging the sample to provide the desired Separation and so on. To obtain accurate results, ...
