PICC catheterization practice model

The utility model discloses a PICC catheterization practice model. The device comprises a simulation human body, a main controller, an alarm indicating lamp used for indicating successful PICC catheterization and a touch switch used for generating an alarm touch signal. Wherein the simulation human body is provided with a simulation trunk and simulation arms; a catheterization channel extending from the middle part of the inner side of the simulation arm to the central vein of the simulation trunk is arranged in the simulation arm; a catheter placing hole communicated with the catheter placing channel is formed in the middle of the inner side of the simulation arm; the touch switch is arranged at the tail end of the catheter placing channel; the alarm indicator lamp is arranged on the surface of the simulation trunk; the device has the effects that medical staff without experience can be treated; before PICC catheterization practical operation is carried out on a patient, a catheter is inserted into the cathe
