[0002] With the continuous development of society and the improvement of people's living standards, more and more attention is paid to the examination of cardiovascular and cerebrovascular diseases, and the number of people who die of cardiovascular and cerebrovascular diseases every year is countless. Such as coronary heart disease, cerebrovascular disease, etc. Arterial examination helps to diagnose and monitor related diseases such as hypertension and hyperlipidemia, and timely detection of arterial problems can prevent the occurrence of cardiovascular events such as myocardial infarction and stroke, and provide a basis for evaluating the effect of drugs or other treatment methods. Arterial examination is one of the important items in routine physical examination. Therefore, understanding the health status of arteries is very important for early detection and prevention of diseases.

[0003] There are many devices on the market for demonstrating arterial pulse and displaying arterial blood vessel direction. According to the search, the Chinese utility model patent with patent application number CN202020683230.3 discloses an intelligent blood circulation system demonstration instrument, which comprises a substrate and a blood circulation LED lamp strip. The substrate is provided with a blood circulation LED lamp strip and a power supply and a transformer on both sides. The blood circulation LED lamp strip comprises a systemic circulation LED lamp strip and a blood LED lamp strip. The purpose is that the intelligent demonstration instrument simulates the blood circulation system by using LED lamp strips. The lamp strip replaces blood vessels, red light simulates arterial blood, and blue light simulates venous blood. The movement of the light dynamically displays the blood circulation to students. The change of red and blue light in the lamp strip simulates the change of blood, and the adjustment of light speed simulates the change of blood flow rate of a person in different states. Students can break through learning difficulties through direct experience.

[0004] For example, the Chinese utility model patent with patent application number CN202321544294.5 discloses a pulse simulation device, which comprises a simulation skin, a cover, a base, an electromagnetic pulsation assembly, a trigger switch and a control device.

The electromagnetic pulsation assembly is arranged in the cavity and abuts against the lower surface of the simulation skin. The electromagnetic pulsation assembly and the trigger switch are electrically connected with the control device. When the simulation skin is pressed downward, the trigger switch is triggered and sends a signal to the control device. The control device sends an electric pulse signal to the electromagnetic pulsation assembly to drive the simulation skin to jump up and down, thereby realizing pulse jump simulation. The electromagnetic assembly saves space and is convenient to install and maintain.

[0018] The specific embodiments of the utility model are further described below in combination with the drawings. It needs to be explained here that the description of these embodiments is used to help understanding the utility model, but does not constitute the limitation to the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0019] In the description of the utility model, it needs to be understood that the orientation or positional relationship indicated by terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" are based on the orientation or positional relationship shown in the drawing, and only for the convenience of describing the utility model and simplifying the description, and not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, so it cannot be understood as the limitation to the utility model.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0021] like Figs. 1-2 As shown, the arterial vascular display device includes a foot liner 1, a simulated foot skin 2, a simulated pulse component 3, a flexible circuit board 4, a control module 5, and a power module 6. The foot liner 1 is installed inside the simulated foot skin 2. The simulated pulse component 3 and the flexible circuit board 4 are both installed on the foot liner 1. The simulated pulse component 3 contains a vibrator 7 and a touch sensor 8. The flexible circuit board 4 has an LED light strip 9. The power module 6, vibrator 7, touch sensor 8, and LED light strip 9 are all electrically connected to the control module 5. It is understood that the foot liner 1 and the simulated foot skin 2 can be made of silicone or similar materials. The power module 5 can be a general-purpose lithium battery or similar device, providing the power required by the control module 5 without the need for an additional power supply, facilitating model movement and portability, and suitable for different teaching scenarios. The vibrator 7 can be a general-purpose vibration motor or similar device. The touch sensor 8 can be a general-purpose pressure sensor or similar device. This arterial vascular display device is mainly used for the pulsation and display of the dorsalis pedis artery, but can also be used for other arteries, such as the carotid artery, femoral artery, radial artery, and brachial artery.

[0022] Specifically, the LED light strip 9 is equipped with several equally spaced red LED indicator lights 10. The greater the pressure applied by the finger, the higher the pulse frequency output by the control module 5, and the stronger the vibration of the vibrator 7. The control module 5 adjusts the light intensity of the LED light strip 9 and controls the order in which each red LED indicator light 10 lights up and turns off, creating a flowing illumination and extinguishing sequence. The control module 5 uses a microcontroller, such as an 80C51 chip or an STM32 chip, which is electrically connected to the power module 6, the vibrator 7, the touch sensor 8, and the LED light strip 9 via power line 11. Understandably, when a finger touches the simulated foot skin 2 and presses down, the touch sensor 8 senses the pressure signal applied to the simulated pulse component 3, converts the pressure signal into an electrical signal, and transmits it to the control module 5. The control module 5 then outputs pulses of a corresponding frequency to drive the vibrator 7 to pulsate. The simulated pulse component can only detect a pulse when touched; it does not pulsate when not touched. The greater the pressure applied during the touch, the more clearly the pulse is detected, consistent with clinical practice. The artery display can have multiple modes, indicating the direction of arteries and blood flow.

[0023] It can be understood that, in practical application process, this pressure sensor is resistance type, when there is pressure to apply its surface, internal resistance value changes, the greater the force, the greater the resistance change. The pressure sensor transmits the pressing signal to the mainboard (ie control module 5) through the wire, and the mainboard outputs a certain frequency pulse after collecting the pressing signal of the pressure sensor by AD, drives the vibrator 7 on the analog pulse assembly, thereby simulating the pulsation of pulse. The greater the pressing degree, the stronger the pulse output by the mainboard, and the stronger the pulsation of the vibrator 7. A flexible circuit board is installed directly above the analog pulse assembly, and a plurality of red LED indicator lamps are uniformly arranged on the flexible circuit board, which is used for the direction of model arterial blood flow and the position of artery in foot, the light intensity of the red LED indicator lamp is adjusted by adjusting the output PWM frequency and duty cycle of the control mainboard, and the order of each red LED indicator lamp is controlled to light up and extinguish in turn, so that the light can penetrate the simulation foot skin 2, and the outside can be clearly seen, thereby simulating the direction and position of blood flow.

[0024] It can be understood that, the utility model discloses reasonable design, unique structure, and the simulation pulse assembly 3 and flexible circuit board 4 are installed in the foot lining 1, are wrapped through simulation foot skin 2, and the whole foot structure is simulated, and the human physiological structure is met. The simulation pulse assembly 3 and flexible circuit board 4 drive the pulsation of pulse and the display of blood vessel and the direction of blood flow through control module 5, the simulation pulse assembly 3 is provided with touch sensor 8, and after the touch signal is transmitted to control module 5, control module 5 drives the vibrator 7 on the simulation pulse, thereby generating pulsation. A plurality of red LED indicator lamps 10 are uniformly arranged on the flexible circuit board 4, and the light of the red LED indicator lamp is driven by control module 5 to drive its brightness and light-out condition, and the light penetrates the foot skin, so that the direction of blood vessel and the direction of blood flow are observed on the outer surface of foot skin. The utility model can be applied to the demonstration of whole body artery, blood flow direction and artery pulsation, and has the advantages of simple structure, easy transplantation and convenient installation. The utility model can work independently of external power supply, and can work for a long time, which is convenient for outdoor training.

[0025] The embodiments of the utility model are described in detail in combination with the drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
