FIELD: medicine, in particular, equipment for blood sampling and transfusion of blood, infusion solutions and other liquids.
SUBSTANCE: blood sampling apparatus has pipe comprising casing and inner cavity, injection needle and needle for connection to container for blood. Injection needle is connected to one end of pipe body. Pipe body comprises at least two regions having different tensile strength values and/or different values of maximal forces, which identical members of these regions may overcome without breakage. Apparatus of such construction allows blood samples to be effectively taken in case of impossibility to create pressure difference in blood vessel-apparatus-blood container system.
EFFECT: increased efficiency in blood sampling, reduced loss of blood upon sampling of small amounts of blood, enhanced reliability in operation, reduced time for blood sampling and decreased length of apparatus.
