断头取血 这是较常用且简便的一种取血方法，操作时一手抓住动物，另一只手用剪刀剪掉其头部，立即将鼠颈部向下，提起动物，并对准已备好的容器（容器内事先放入抗凝剂），使鼠血快速滴入容器内。眶动脉或眶静脉取血 将动物倒持，然后压迫眼球，使其突出充血后，用止血钳迅速摘除眼球，眼眶内会很快流出血液，让血滴入加有抗凝剂的玻璃器皿内，直至血流不出为止。一般情况下可取得相当于动物体重 4%～5% 的血液量。血流完动物即死亡，此法只适用于一次性取血。

Due to the gentle temperament and easy feeding of rabbits, Mianyang is commonly used for experiments on the effects of drugs on the heart, blood pressure, and respiration, as well as for experiments on organophosphorus pesticide poisoning and rescue. It can also be used for studying the effects of drugs on the central nervous system, body temperature experiments, pyrogen tests, and research on contraceptives. Compared with rabbits, cats have strong tolerance to surgical procedures and stable blood pressure, which is why they are often used in blood pressure experiments, as well as in the study of cardiovascular and central nervous system drugs.
There are two ways to capture the mouse. One is to lift the tail of the mouse with the right hand. The Neijiang experimental mouse places it on the cage cover or other rough surface, and gently pulls it back and up. At this time, the mouse's forelimbs tightly grasp the rough surface, quickly pinch the skin on the back of the mouse's neck with the left thumb and index finger, and clamp the root of the tail with the little finger and palm to fix it in the hand. Another method is to grab the tail of the mouse with only the left hand, then pinch the neck skin with the thumb and index finger, and then clamp the root of the tail with the ulnar side of the palm and little finger. The first method is simple and easy to learn, while the second method is more difficult, but it is fast to capture and administer drugs.
Cutting off the head to take blood is a commonly used and simple method of taking blood. When operating, one hand grabs the animal, while the other hand uses scissors to cut off its head. Immediately, the mouse's neck is lowered, the animal is lifted, and the prepared container (pre placed with anticoagulant) is aligned to allow the mouse blood to quickly drip into the container. Take blood from the orbital artery or vein, hold the animal upside down, and then compress the eyeball to protrude and congestion. After that, use a hemostatic forceps to quickly remove the eyeball. Blood will quickly flow out of the orbit, allowing it to drip into a glass container filled with anticoagulants until no blood can flow out. Generally, a blood volume equivalent to 4% to 5% of the animal's body weight can be obtained. Animals die after completing blood flow, and this method is only applicable to one-time blood collection.
