In the simulated blood vessel 3, the flow of blood is simulated to form a simulated pulse; the part of the simulated blood vessel 3 located in the simulated arm 2 is attached to the top of the simulated blood vessel 3 by gluing; the air pump 8 is connected to the simulated arm 2, and air is filled into the simulated arm 2 to make the simulated arm 2 made of latex expand and have support; the base 1 is also equipped with a controller 9, and the controller 9 is provided with a control chip, and the control chip is a single-chip microcomputer chip with model number STC12C5A60S2, and the control chip is electrically connected to the hydraulic pump 4, and the accumulator 5 is equipped with a hydraulic sensor capable of detecting the liquid pressure in the accumulator 5, and the hydraulic sensor is electrically connected to the control chip, and the pulse valve 6 is electrically connected to the control chip, and the controller 9 is provided with a display screen for displaying the pressure of the hydraulic sensor.When the simulator is simulating, the air pump 8 is started by the controller 9 to fill the simulated arm 2 with air, so that the simulated arm 2 expands and has support, and the inflation amount is controlled to make the expansion degree of the simulated arm 2 closer to the softness of human skin; then the hydraulic pump 4 is started by the controller 9 to fill the accumulator 5 with simulated blood, so that hydraulic pressure is formed in the accumulator 5, and the hydraulic sensor in the accumulator 5 transmits the detected hydraulic pressure in the accumulator 5 to the control chip and displays it on the display screen for easy observation. According to the experience of old Chinese medicine practitioners, it is adjusted to a suitable pressure in the accumulator 5, and then the pulse valve 6 is started to open and close regularly, so that the simulated blood in the accumulator 5 is regularly pumped into the simulated blood vessel 3 under the action of hydraulic pressure to simulate the pulse; the finger is pressed on the simulated blood vessel 3 on the simulated arm 2 to simulate the pulse diagnosis. Training; when the hydraulic pressure in the accumulator 5 is lower than the preset pressure, the control chip controls the hydraulic pump 4 to input simulated blood into the accumulator 5, so that the accumulator 5 always maintains a constant hydraulic pressure, so as to form a pulse flow of constant intensity under the control of the pulse valve 6, which is convenient for trainees to learn to take the pulse; by adjusting the hydraulic pressure in the accumulator 5, the strength of the pulse pumped into the simulated blood vessel 3 can be adjusted; the pulse valve 6 is electrically connected to the control chip, and the opening and closing speed of the pulse valve 6 can be controlled to adjust the speed of the pulse in the simulated blood vessel 3; the invention can adjust the strength and speed of different pulse beats according to the experience of old Chinese medicine practitioners, and then let the trainees truly feel the pulse beats of different diseases, so that the experience of old Chinese medicine practitioners can form specific pulse images, which can greatly improve the training efficiency of Chinese medicine practitioners and enable the experience of old Chinese medicine practitioners to be efficiently and quickly inherited.

[0020] The simulated arm 2 is connected to an electromagnetic control valve 10 through an exhaust pipe, and the electromagnetic control valve 10 is connected to a control chip, and the air pump 8 is also connected to the control chip. The exhaust of air in the simulated arm 2 is controlled by the electromagnetic control valve 10, and the hardness of the surface of the simulated arm 2 can be felt based on experience. The controller 9 controls the air pump and the electromagnetic control valve 10 to inflate and deflate the simulated arm 2, so that the feel of the surface of the simulated arm 2 is closer to the feel of a real person's arm, making the pulse simulation more realistic, the simulation effect better, and the pulse training effect better.

[0021] The simulated arm 2 is provided with three adjusting devices 11 for controlling the cross sections of three positions of the simulated blood vessel 3. By adjusting the cross sections of the three positions of the simulated blood vessel 3, the flow velocity and intensity flowing through the three positions are changed, thereby simulating the pulse beating of the Cun pulse, the Guan pulse, and the Chi pulse. The adjusting devices 11 can respectively simulate the pulse conditions of the Cun pulse, the Guan pulse, and the Chi pulse, so that the trainees can feel the pulse conditions of different positions when learning to feel the pulse, thereby achieving a better learning effect.

[0022] The adjusting device 11 includes a support plate 111, a tightening belt 112, a changing pulley 113, and a tightening mechanism; the support plate 111 is elliptical and fits with the inner wall of the simulated arm 2 for support, and a notch is provided at the upper end of the support plate 111 to facilitate the passage of the simulated blood vessel 3; the middle part of the tightening belt 112 is wrapped around the simulated blood vessel 3, and the two ends are respectively passed around the changing pulleys 113 fixed on both sides of the top of the support plate 111, and the tightening belt 112 is used to tighten the simulated blood vessel 3 to both sides through the changing pulley 113 to avoid pulling the simulated blood vessel 3 downward to damage the simulated blood vessel 3, and is connected to the tightening mechanism; the tightening mechanism tightens the two ends of the tightening belt 112 to shrink the simulated blood vessel 3 and reduce the cross-section of the simulated blood vessel 3, and the tightening mechanism is relaxed to increase the cross-section of the simulated blood vessel 3. The tightening mechanism is used to tighten the two ends of the tightening band 112, so that the tightening band 112 will shrink the simulated blood vessel 3, thereby reducing the local cross-section of the simulated blood vessel 3, so that when the pulse flow passes through this position, the intensity generated on the wall of the simulated blood vessel 3 is different, thereby simulating different pulse conditions at different positions of the simulated blood vessel 3, allowing the trainees to feel the different pulse conditions of the inch pulse, the guan pulse, and the chi pulse at the same time.

[0023] The tightening mechanism includes a tightening wheel 114 installed at the inner bottom of the simulated arm 2, and a micro motor 115 connected to the tightening wheel 114, and both ends of the tightening belt 112 are fixed and wound around the tightening wheel 114. The tightening wheel 114 is driven by the micro motor 115 to rotate, so that the tightening belt 112 is tightened on the tightening wheel 114, thereby pulling the tightening belt 112 to shrink the simulated blood vessel 3 and reduce the cross section of the simulated blood vessel 3.

[0024] When the tightening band 112 is wound around the simulated blood vessel 3, one end of the tightening band 112 passes around the simulated blood vessel 3 and passes through the strip hole 116 provided on the tightening band 112. Passing the tightening band 112 through the strip hole 116 can make the tightening band 112 wound around the simulated blood vessel 3 shrink along the cross-sectional direction of the simulated blood vessel 3 when shrinking the simulated blood vessel 3, thereby preventing the tightening band 112 from bending the simulated blood vessel 3.

[0025] The micro motor 115 is electrically connected to the control chip, and the controller 9 is provided with a control button connected to the control chip for controlling the forward and reverse rotation of the micro motors 115 in the three regulating devices 11; the controller 9 is provided with a control switch for controlling the start of the hydraulic pump 4, the operation of the pulse valve 6, the start and stop of the air pump 8, and the opening and closing of the electromagnetic control valve 10. The control button on the controller 9 transmits a signal to the control chip, so that the micro motors 115 of the three regulating devices 11 rotate forward and reverse, thereby tightening and loosening the tightening belt 112, thereby adjusting the cross-sectional area of ​​the three positions of the simulated blood vessel 3, so that the three positions simulate different pulses of the inch pulse, the guan pulse, and the chi pulse, respectively, and the opening and closing and start and stop of the hydraulic pump 4, the pulse valve 6, the air pump 8, and the electromagnetic control valve 10 are controlled by the corresponding control switches of the hydraulic pump 4, the pulse valve 6, the air pump 8, and the electromagnetic control valve 10.

[0026] The pulse simulation method based on the above-mentioned traditional Chinese medicine pulse simulator comprises the following steps: S1, start the air pump 8 to fill the simulated arm 2 with air, so that the simulated arm 2 expands and has support; S2, start the hydraulic pump 4 to fill the accumulator 5 with simulated blood, so that hydraulic pressure is formed in the accumulator 5, and then start the pulse valve 6 to open and close the pulse valve 6 regularly, so that the simulated blood in the accumulator 5 is regularly pumped into the simulated blood vessel 3 under the action of hydraulic pressure to simulate the pulse; press the finger on the simulated blood vessel 3 on the simulated arm 2, so as to perform pulse diagnosis simulation training; S3, the hydraulic pressure sensor in the pressure accumulator 5 transmits the information to the control chip and displays it. By adjusting the hydraulic pressure in the pressure accumulator 5, the pulse strength pumped into the simulated blood vessel 3 is adjusted. The pulse valve 6 is electrically connected to the control chip, and the opening and closing speed of the pulse valve 6 can be controlled to adjust the speed of the pulse in the simulated blood vessel 3. S4, through the control button on the controller 9, control the tightening belts 112 of the three adjustment devices 11 to contract the simulated blood vessel 3, so that the pulse strength and the rise and fall of the simulated blood pulse flow through the three contracted positions are different, thereby simulating the different pulse beats of the Cun pulse, Guan pulse and Chi pulse when taking the pulse.

[0027] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
