Abstract:
1. A disposable blood analysis cartridge comprising: a sample introduction port; a sample collection reservoir for receiving a blood sample from the sample introduction port; an absorbance measurement channel including a cuvette and a first gas permeable membrane located downstream of the cuvette; an optical scattering measurement channel including a hydrodynamic focusing region and a second gas permeable membrane located upstream of the hydrodynamic focusing region; one or more valves disposed fluidly between the sample collection reservoir and the absorbance measurement channel and fluidly between the sample collection reservoir and the optical scattering measurement channel; one or more vacuum ports in fluid communication with the absorbance measurement channel through the first gas permeable membrane, and in fluid communication with the optical scattering measurement channel through the second gas permeable membrane; and wherein when a negative pressure is applied to the one or more vacuum ports, at least part of the blood sample is drawn from the sample collection reservoir, through the one or more valves and at least partially into the absorbance measurement channel and the optical scattering measurement channel.
