AUTOMATIC INTRODUCTION OF REFERENCE FLUIDS IN AN APPARATUS FOR ANALYSIS OF PHYSIOLOGICAL FLUIDS

摘要

The apparatus for analysis has means for automatic introduction of reference fluid for the apparatus. The apparatus comprises an inlet member with a displaceable inlet tube, programmable control means for control of the introduction of fluid into the apparatus, a holder for simultaneously holding several sealed containers with reference fluid, and opening means for opening a sealed container. The apparatus further comprises first movement means for bringing a container selected by the programmable control means and the opening means into position in relation to each other, second movement means for bringing the opened container and the inlet member into position in relation to each other, displacement means for displacing the inlet tube into the reference fluid, and third movement means for removing the container and the inlet member from each other. The containers comprise a container body and a cap having a penetration part provided with a through hole and being arranged for breaking open the sealed container when the cap is moved relative to the container body. The opening means comprises a press element for moving the cap of a container relative to the container body in order to break open the sealed container by pressing the penetration part of the cap into the container.
