  • Sample entry device for delivering medical samples to an analyzer
    Patent number: 7186384
    Abstract: The invention relates to a sample entry device for delivering medical samples, preferably blood samples, from diverse sample containers to an analyzer, wherein sample transfer between sample intake and measuring cells of the analyzer taking place via gas-tight sample lines. According to the invention a fixed intake needle is provided at the entry side of the analyzer, which includes an elastic intake element that is axially slideable on the intake needle and has a conical intake opening. In addition, a holding element is provided, which is axially slideable parallel to the intake needle and can be shifted relative to the intake element. In a first position the holding element exposes the intake element and in a second position places a conical opening above the intake element to accommodate a syringe.
