Medical sample introducing apparatus in an analyzer

Input device samples (1) for the entry of medical samples, preferably blood samples from different containers sampling (10, 11) in an analyzer (3), where the transport of samples between input samples and the measuring cells (6) of the analyzer (3) is performed ducted gas permeable (5) samples, so a needle inlet (4) is arranged fixed on one side of the input samples into an analyzer (3) having an input element (8) resilient, displaceable axially by the inlet needle (4) having an orifice conical inlet (9) and is available a fastener (16) slides axially and in parallel to the intake needle (4), which releases in a first position the input element (8) and in a second position places a conical opening (17) on the input element (8) to receive a syringe plunger (11).
