The invention discloses a training model for artery and vein hemostasis operation, which can facilitate trainees to observe vivid artery and vein hemorrhage. The training model of the invention comprises a simulated man limb, a liquid circulation system and a control circuit box, wherein, the liquid circulation system comprises a circulation branch that is formed by sequentially connecting a liquid input pipe fitting, a liquid pump, an electromagnetic valve and a liquid output pipe fitting; the simulated man limb is composed of the materials that have similar flexibility to that of human muscles, a liquid line in the limb is connected with the liquid output pipe fitting, the surface of the simulated man limb is provided with a substitutable wound, a liquid recovery box is hermetically covered on the wound and is connected with the liquid input pipe fitting, and a pressure sensor is arranged in the simulated man limb; the control circuit box consists of a single chip microcomputer system, a keyboard and a display circuit, and the single chip microcomputer system controls the liquid pump and the electromagnetic valve. The training model of the invention provides the vivid simulation of the artery and vein hemorrhage, and the flowing speed of the liquid can be controlled, thus being able to simulate the hemorrhage under traumatic conditions with different levels.
