The control circuit board 4 is placed inside the pulse generator 8. The control circuit board 4 adopts an L298N DC stepper motor driver board, and uses L298N as the main driver chip, which has the characteristics of strong driving ability, low heat generation, and strong anti-interference ability. Three groups of motors 3 are arranged on the inner top of the pulse generator 8, and the output end of the motor 3 is connected to a rotating shaft 10, and a fan-shaped protrusion 11 is provided on the rotating shaft 10. The motor 3 adopts a fan-shaped eccentric wheel micro-vibration motor of model CM-RK555, which has the characteristics of strong vibration, large amplitude and long life. The control circuit board 4 is connected to the motor 3 and the touch sensor 5 respectively.

[0024] The surface material of the arm model 6 is a silicone layer, which simulates the touch and appearance of a real human arm, providing learners with a realistic learning experience. Three annular bosses 12 are provided on the top of the pulse generator 8, and the touch sensor 5 is placed on the annular boss 12 to feedback the learner's pressing position and force information. The touch sensor 5 adopts an annular film pressure sensor with model RP-R24H14. The upper end of the touch sensor 5 is provided with a film 17 located on the inch ruler of the arm model 6. When the learner presses the film 17 on the arm model 6 with his fingers, the touch sensor 5 will capture the pressing position and force, and transmit this information to the control circuit board 4. After receiving the information, the control circuit board 4 will process and display the pulse data on the display 1 or other devices for the learner to observe and analyze.

[0025] A through hole 13 is provided in the middle of the annular boss 12, and a thimble 15 is provided in the through hole 13 to move in the vertical direction, the lower part of the thimble 15 is in conflict with the fan-shaped protrusion 11, and the upper part of the thimble 15 is in contact with the film 17; a limiting ring 14 is provided at the bottom of the through hole 13, and a convex edge 16 is provided in the middle of the thimble 15, and the convex edge 16 is arranged above the limiting ring 14, and the lower part of the thimble 15 is inserted into the limiting ring 14. When the motor 3 is working, driven by the eccentric wheel of the rotating shaft 10, the fan-shaped protrusion 11 can drive the thimble 15 to move in the vertical direction just below the film 17, simulating the beating of different pulses, so that learners can intuitively feel the changes in the pulse.

[0026] One side of the pulse generator 8 is provided with seven interface terminals 9 connected to the control circuit board 4. The pulse diagnosis teaching aid also includes a display 1, which is connected to the control circuit board 4 via the corresponding interface terminals 9.
