  • Blood analyzer
    Publication number: 20030029254
    Abstract: A blood analyzer has a sensor, a sample handler having a sample container station with a sample container bed adapted for holding a sample container, and a means for linearly moving a stirring element inside the sample container when the sample container is arranged in the sample container bed, and a means for transferring a sample from the sample container to the sensor. The blood analyzer is capable of stirring blood samples.

  • Apparatus for analysis of samples of fluids
    Patent number: 5417121
    Abstract: New apparatus for measuring parameters such as pH, pCO.sub.2, pO.sub.2, and Hb content of physiological fluids, especially blood, is described. The apparatus comprises novel means for suspending reagent vessels (34, 35, 40, 45, 50) having shoulders (51, 52) and containing calibrating solutions, rinsing solutions etc., as well as for suspending a liquid waste vessel (26) by suspending the vessels between rods (53, 54) fed to the analyser. The reagent vessels are provided with caps (55, 58) at the top and include liquid reagent conduit extending from the outlet aperture of the cap down into the liquid. When the vessel is mounted on the analyser a fixed inlet tube extending horizontally outwardly from the analyser penetrates a seal across the outlet aperture and connects with the liquid reagent conduit.
