Puncture exercising machine

The utility model discloses a puncture exercising machine which is composed of a simulated blood vessel model and a puncture display device. The simulated blood vessel model is composed of a protective layer, a blood vessel layer and a skin layer successively from inside to outside. The puncture display device comprises a high resistor, a low resistor, a red indicating lamp, a green indicating lamp, a display meter, a power supply and a needle head. When the needle head stabs into the blood vessel layer, the indicator of the display meter is oriented to a puncture area, puncture of the needle head into the blood vessel is represented. When the needle head penetrates through the blood vessel layer and contacts with a metal sheet, the indicator of the display meter is oriented to a penetrating area, thereby representing large penetrating strength and high depth of the needle head. When the needle head stabs the metal sheet at the bottom of the blood vessel layer, the indicator of the display meter is oriented to an oblique puncture area, thereby representing incorrect puncture direction and incorrect puncture angle of the needle head. When the needle head does not stab the blood vessel, the indicator of the display meter is oriented to a non-stabbing area, thereby representing incorrect needle head puncture position and incorrect needle head puncture direction.
