Abstract
An apparatus for taking a sample blood collected in a vacuum type blood collection tube having a main tube and a cap hermetically secured to an opening of the main tube, including a suction nozzle which is inserted into the main tube through the cap and an air supply nozzle which is also inserted into the main tube through the cap. During the sample blood is sucked into the suction nozzle, an air is supplied into the main tube through the air supply tube such that a pressure inside the main tube is kept substantially at the atmospheric pressure. The sample blood may be sucked, while the main tube is moved substantially up side down. In case of removing the cap by a cap removing mechanism, the air supply nozzle is inserted into the main tube through the cap and the pressure inside the main tube is increased to the atmospheric pressure or a positive pressure. A given amount of the blood sample can be taken out of the tube without being affected by the pressure inside the tube.
