摘要
A blood sampling device comprises a pointed cannula (3, 23) at each end, a pre-evacuated sample container (1, 21) with a self-sealing stopper (2, 22) which can be perforated, a self-sealing membrane (8,28) which can be perforated and a blood-viewing chamber (7, 27) the walls of which are surrounded by transparent material arranged in front of the stopper (2, 22) in the direction of perforation. The chamber (7, 27) is arranged on the stopper (2, 22) and is sealed off essentially from the sample container (1, 21) by said stopper (2, 22) and from the patient by the membrane (8, 28).
