Novel anti-coagulation blood sampling bag

The utility model provides a novel anti-coagulation blood sampling bag which is mainly used for blood stations of medical institutions such as hospitals. A thermal insulation cover is arranged outside a blood sampling bag body. Blue ice is placed in the thermal insulation cover so that blood in the blood sampling bag body can be kept at a certain temperature. A sealing plug is arranged at the bag opening of the blood sampling bag body. A one-way hole is formed in the sealing plug so that the extracted blood can be prevented from backflow. The inner end of the sealing plug is connected with an anti-coagulation bag. An appropriate number of blood anti-coagulation agents are contained in the anti-coagulation bag so that the preservation time of the blood can be prolonged. The novel anti-coagulation blood sampling bag is reasonable in design, convenient to use, and capable of preserving the collected blood for a long time and lowering the work difficulty of medical staff of the blood stations.
