  • the disadvantage here is that a large number of adjustment processes must be carried out between the individual components of the receiving device in order to ensure proper functioning. Likewise, an intervention into the interior of the adjusting sleeve is still possible, which makes it undesirable Sting injuries can occur for the operating personnel.
  • a further safety acceptance device has become known from US 2002/0099355 AI, in which the entire needle carrier with the angularly designed puncture needle for the blood sample collection tube can be reset by the operator in a separate longitudinal guide from the use position to the disposal position.
