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.

Apparatus for analysis of samples of fluids

Container for waste expelled from a blood gas analyzer or the like

A blood sampling device (10), in particular intended for arterial blood sampling and blood gas analysis, is disclosed. The sampling device is provided with valve means which in the dry state permits expulsion of gas from the sampler reservoir (18), but which automatically closes on contact with blood. The valve means comprises two mating surfaces (21, 26) retained apart by an interlayer of a porous or fluffy fibrous material (22), which collapses on contact with a liquid.
