A device particularly suited for collecting and dispensing an arterial blood sample. A needle (1) is connected to a flexible transparent tube (5) that includes an air exit vent (7) with a nonwet filter (8) so air, but not blood, can exit the filter under arterial blood pressure. A clamp (10) on the tube (5) pinches off a segment of blood and longitudinally strips such blood segment from the tube (5). The tube (5) has an oxygen blocking coating (39) which is covered with a dry anticoagulant coating (40). |
