Description

Technical Field

[0001] The invention relates to the technical field of traditional Chinese medicine diagnosis and human body simulation, in particular to a human pulse simulation device based on an elastic silicone rod and a method thereof. Background Art

[0002] The human pulse actually reflects the body's condition, and pulse diagnosis in Traditional Chinese Medicine (TCM) is based on this principle. However, in practice, TCM practitioners often lack a large number of patients to study, so beginners can only learn through simulation training. However, human body simulations often struggle to replicate the pulse fluctuations of a real patient. This is primarily due to two reasons. First, pulse fluctuations vary from person to person, and universally simulating such a wide range of pulse types places high demands on the simulation system. Furthermore, the pulse itself is a vascular fluctuation, and the human circulatory system is vast and complex, making it extremely difficult to simulate such a complex system using simple devices.

[0003] Despite these conditions, many proposals for simulating the human pulse have been proposed, primarily falling into two categories. One utilizes the vibrations of a motor to simulate the pulse. While relatively simple, this method can only simulate pulse fluctuations and cannot address certain special conditions, such as the pulse of people with arteriosclerosis. Another approach mimics the blood circulation system, using a pump to circulate liquid or air through pipes to simulate real blood circulation and thus achieve pulse simulation. This approach avoids the problems of the first approach, but comes with the system complexity and maintenance difficulties associated with liquid or air circulation. Furthermore, the device is bulky and expensive, making it difficult to scale.

[0004] Chinese patent application CN105078430B discloses a pulse wave blood pressure simulator, comprising: a blood pressure simulation device for simulating human blood pressure signals, comprising a flexible rubber tube filled with gas and capable of elastic expansion and contraction, and an extrusion assembly for squeezing the rubber tube, the rubber tube being disposed within the extrusion assembly; a pressure sensor for detecting the pressure within the rubber tube, connected to the rubber tube; a pulse wave simulation device for simulating human pulse wave signals, comprising an air pump for providing a pulsed airflow; and a controller for controlling the operating states of the blood pressure simulation device and the pulse wave simulation device and for collecting feedback information from the pressure sensor. The blood pressure simulation device, the pulse wave simulation device, and the pressure sensor are all electrically connected to the controller. This pulse wave blood pressure simulator can simulate human blood pressure and pulse signals and can be used to accurately test a sphygmomanometer; however, the overall structure is complex, bulky, costly, and inconvenient to maintain.

[0005] Therefore, in summary, there is an urgent need for a human pulse simulation device and method based on an elastic silicone rod that has a simple structure, is easy to operate, can overcome the simulation deficiencies of the traditional motor vibration method, and avoids the system complexity problems caused by liquid or air circulation; however, there is currently no report on this new type of human pulse simulation device and method based on an elastic silicone rod. Summary of the Invention

[0006] The purpose of the present invention is to provide a human pulse simulation device based on an elastic silicone rod.

[0007] To achieve the above object, the technical solution adopted by the present invention is:

[0008] A human pulse simulation device based on an elastic silicone rod comprises an aluminum block substrate, a main control circuit, a stepper motor, a threaded aluminum block, a voice coil motor, a soft silicone rod, a soft silicone pad, and an aluminum block; the aluminum block substrate is a flat aluminum block, and an aluminum block protrusion is provided on the upper right side thereof, and the aluminum block protrusion and the aluminum block substrate are an integrated structure, and a transverse through hole is provided in the middle position of the aluminum block protrusion, the threaded aluminum block passes through the through hole in the middle of the aluminum block protrusion and is connected to the stepper motor, and the stepper motor is located on the left side of the aluminum block protrusion, and its bottom surface is fixedly connected to the aluminum block substrate; a There is an aluminum block A, and the threaded aluminum block is vertically fixedly connected to the aluminum block A; an aluminum block B is also provided at the far left end of the aluminum block protrusion, and the two ends of the soft silicone rod pass through the aluminum block A and the aluminum block B horizontally respectively, and are pasted on the aluminum block A and the aluminum block B; a layer of soft silicone pad is tightly attached to the top of the soft silicone rod; a voice coil motor is provided on the right side of the aluminum block A, the bottom end of the voice coil motor is fixed on the aluminum block substrate, and the upper end thereof supports the soft silicone rod; a main control circuit is also provided on the aluminum block substrate, and the main control circuit is electrically connected to the voice coil motor and the stepper motor respectively to drive the two motors to move.

[0009] In the above-mentioned human pulse simulation device based on the elastic silicone rod, as a preferred solution, the aluminum block A is located above the aluminum block substrate and has no direct contact with the aluminum block substrate.

[0010] In the above-mentioned human pulse simulation device based on elastic silicone rod, as a preferred solution, the aluminum block B is located above the aluminum block base plate, and its bottom is fixedly connected to the aluminum block base plate.

[0011] In the above-mentioned human pulse simulation device based on elastic silicone rod, as a preferred embodiment, the shape of the through hole in the aluminum block protrusion matches the shape of the threaded aluminum block, and the size of the through hole is slightly larger than that of the threaded aluminum block.

[0012] In the above-mentioned human pulse simulation device based on the elastic silicone rod, as a preferred solution, the threaded aluminum block is parallel to the soft silicone rod and is located below the soft silicone rod.

[0013] In the above-mentioned human pulse simulation device based on the elastic silicone rod, as a preferred solution, the forward or reverse rotation of the stepper motor can control the left and right movement of the threaded aluminum block, thereby controlling the left and right movement of the aluminum block B.

[0014] Yet another object of the present invention is to provide a method for simulating human pulse.

[0015] To achieve the above second purpose, the technical solution adopted by the present invention is:

[0017] The main control circuit controls the number of forward and reverse rotation steps of the stepper motor, thereby controlling the left and right movement distance of the threaded aluminum block. Movement to the left can reduce the tightness of the soft silicone rod to simulate the relaxation of blood vessels. Conversely, movement to the right can increase the tightness of the soft silicone rod to simulate the hardening of blood vessels.

[0018] The main control circuit controls the expansion and contraction of the voice coil motor, thereby driving the soft silicone rod to vibrate. By adjusting the expansion and contraction amount and frequency of the voice coil motor, different vibration modes of the soft silicone rod can be achieved, thereby simulating different beating patterns of the human pulse, that is, different pulse conditions.
