Preferably, a bionic blood vessel net used for conveying colored liquid is arranged in the feedback layer, and a plurality of microfiltration holes communicated with the feedback layer are formed in the side wall of the bionic blood vessel net; above-mentioned intraformational bionical blood vessel net of feedback is so that the intraformational blood vessel of human subcutaneous tissue of simulation, make bionical blood vessel net and feedback layer can make up each other and form the subcutaneous tissue that has the oozing blood function, with the bionical human skin of simulation, make medical staff plant the hair after targetting in place, thereby feedback intraformational liquid can feed back the phenomenon of bleeding when planting the hair in real time, real-time supervision when making things convenient for medical staff to practice, the micro-filtration pore setting on the bionical blood vessel net, so that supply the intraformational liquid of feedback at any time, guarantee the stable feedback action in feedback layer.

Preferably, the bionic blood vessel net is provided with a liquid inlet communicated with a device for storing colored liquid outside; the setting of above-mentioned inlet for this bionical blood vessel net can communicate with external device, keeps the liquid in the bionical blood vessel net sufficient, prevents that liquid supply is insufficient and influence feedback work.

Preferably, the simulated epidermis layer and the simulated dermis layer are in sealed connection, and the simulated dermis layer and the feedback layer are in sealed connection; the mutual sealing arrangement among the simulation epidermal layer, the simulation dermal layer and the feedback layer ensures that the simulation epidermal layer, the simulation dermal layer and the feedback layer are mutually and tightly connected, thereby avoiding the mutual separation among the simulation epidermal layer, the simulation dermal layer and the feedback layer, influencing the hair transplantation practice, avoiding the liquid in the feedback layer from seeping out from the space between the simulation epidermal layer and the simulation dermal layer or the space between the simulation dermal layer and the feedback layer, and ensuring the normal stability of the device.

Therefore, the utility model has the characteristics of truly simulating the skin of a person, improving the hand feeling, enhancing the practice quality of practice, feeding back the hair transplantation in-place information in real time, facilitating the observation of medical staff, improving the hair transplantation simulation practice quality and the like.
