The blood collection zone is for storing a quantity of withdrawn blood. It also feeds an initial fraction of withdrawn blood to a communicating blood disposal chamber which has an air permeable liquid sealed end. The second branch of the bifurcated capillary tube is connected to and is in fluid communication with the blood collection zone. It terminates in an opening adapted to receive a blood withdrawal device. Also disclosed is a method of sampling blood from a patient having an artery fitted with a venipuncture device which is attached to an injection site which contains the closed blood sampling device described.
