Especially cardiopulmonary simulation equipment, which can simulate the movement and function of the human cardiopulmonary system, is of great significance for medical education and the research and development of medical equipment.

[0003] However, most of the existing cardiopulmonary simulation devices on the market have complex structures, cumbersome operations, and are difficult to truly reflect the natural movement state of the human heart and lungs. In addition, these devices also have deficiencies in simulating the flexibility and realism of the skin, which undoubtedly reduces the accuracy and realism of the simulation. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bionic cardiopulmonary motion simulation device to solve the problems in the above background art that most of the existing cardiopulmonary simulation devices on the market have complex structures, cumbersome operations, and are difficult to truly reflect the natural movement state of the human heart and lungs. In addition, these devices also have deficiencies in simulating the flexibility and realism of the skin, which undoubtedly reduces the accuracy and realism of the simulation.

[0005] To achieve the above purpose, the utility model provides a bionic cardiopulmonary motion simulation device, including a human body simulation cavity. Inside the human body simulation cavity, there are a battery, a heaving motion simulator and an air pump. The heaving motion simulator includes an airbag. Above the airbag, there is a heaving plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] In this bionic cardiopulmonary motion simulation device, the device adopts an undulating motion simulator, and simulates the undulating motion of the cardiopulmonary through the inflation and deflation of the airbag.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides a bionic cardiopulmonary motion simulation device, as Figures 1-4 shown, which includes a human body simulation cavity 1. Inside the human body simulation cavity 1, there are a battery 2, a heaving motion simulator 3 and an air pump 4. The heaving motion simulator 3 includes an airbag 31. An undulating plate 32 is arranged on the upper part of the airbag 31, and a support plate 34 is arranged at the bottom of the airbag 31. A lifting rod 33 is connected to the bottom of the undulating plate 32. The bottom of the lifting rod 33 passes through the airbag 31 and the support plate 34 and is connected to a fixed cylinder 35. A skin simulation layer 11 is arranged at the top of the human body simulation cavity 1. The bottom of the fixed cylinder 35 is provided with a bottom plate 37. By inflating the airbag 31 through the air pump 4, the undulating plate 32 is lifted. When the air pump 4 inhales, the gas in the airbag 31 is discharged, and the undulating plate 32 descends, thereby simulating the motion of the heart and lungs. In this embodiment, by controlling the air delivery speed and frequency of the air pump 4, the action frequency of the airbag 31 can be adjusted, thereby realizing the control of the simulated heart rate and the simulated respiratory rate.

[0023] In this embodiment, the skin simulation layer 11 is made of silica gel material and can simulate the touch of the skin. The human body simulation cavity 1 is made of hard plastic material to ensure the protection of the internal equipment.

[0024] Specifically, through holes 341 are formed on the surface of the support plate 34. The output end of the air pump 4 is connected to an air charging pipe 41. One end of the air charging pipe 41 passes through the through hole 341 and is connected to the airbag 31.

[0025] Furthermore, a sliding plate 331 is installed at the bottom end of the lifting rod 33, and a return spring 332 is installed outside the lifting rod 33 above the sliding plate 331 to ensure the reset of the lifting rod 33 after the airbag 31 exhausts gas and realize the descending action of the undulating plate 32.

[0026] Furthermore, the battery 2 is connected to the power supply interface of the air pump 4 through a wiring 21 to facilitate the air pump 4 to be powered on for normal operation.

[0027] Furthermore, the number of the heaving motion simulators 3 is two, which are symmetrically arranged left and right inside the human body simulation cavity 1 and are used to respectively simulate the motion of the heart and lungs.

[0028] Further, a support spring 36 is installed between the bottom of the support plate 34 and the top of the bottom plate 37. The support spring 36 is sleeved outside the fixed cylinder 35 to ensure the stability of the support plate 34.

[0029] Further, the bottom of the airbag 31 is adhesively fixed to the support plate 34 to facilitate the positioning of the airbag 31.

[0030] It should be noted that by setting different values on the software to control the inflation and deflation speed and frequency of the air pump, the frequency adjustment of the airbag can be achieved, and thus different heart rates and breathing rates can be realized.

[0031] When the bionic cardiopulmonary motion simulation device of the present utility model is in use, first when the device is started, the battery 2 (power supply component) supplies electrical energy to the air pump 4 (power component) through the wiring 21 to drive it to start working. One end of the air charging pipe 41 connected to the output end of the air pump 4 passes through the through hole 341 on the surface of the support plate 34 and is connected to the airbag 31 (execution component).

[0032] When the air pump 4 works, it inflates the airbag 31 through the air charging pipe 41. The airbag 31 gradually expands and pushes the upper undulating plate 32 (simulation component) to rise. During this process, the lifting rod 33 (transmission component) rises as the undulating plate 32 rises, and at the same time, the reset spring 332 (reset component) is compressed and stores elastic potential energy.

[0033] When the air pump 4 performs an inhalation action, the gas in the airbag 31 is drawn out through the air charging pipe 41, and the airbag 31 begins to contract. At this time, the undulating plate 32 gradually descends under the action of the elastic potential energy released by the reset spring 332, simulating the contraction state of the heart and lungs. This up-and-down process forms a continuous simulation of the cardiopulmonary undulating motion.

[0034] In addition, the human body simulation cavity 1 (housing component) of the device is made of a rigid plastic material to ensure the stability and protection of the internal equipment. The skin simulation layer 11 (simulation component) located at the top of the human body simulation cavity 1 is made of a silicone material, which can realistically simulate the feeling of real skin and improve the authenticity of the simulation and the teaching effect.

[0035] It should be noted that by setting different values on the software to control the inflation and deflation speeds and frequencies of the air pump, the frequency adjustment of the airbag can be achieved, and thus different heart rates and breathing rates can be realized. First, ensure that there is a reliable communication interface between the air pump and the main control board (such as a microcontroller, PLC, or computer), which can be a wired or wireless connection. Write or install the corresponding driver program on the main control board so that instructions can be sent through the software to control the air pump. Develop a user interface (UI) that allows the operator to input the desired inflation / deflation speed and frequency of the air pump. This interface can be a simple text input box or graphical slider or knob controls. In the software background, convert these user-entered values into machine-readable instructions or signals. The software generates corresponding control signals according to the values set by the user. For example, for a PWM (pulse width modulation)-controlled air pump, the software adjusts the duty cycle of the PWM signal to change the operating speed of the air pump. These control signals are sent to the air pump through the hardware interface to precisely control its inflation / deflation speed and frequency. To ensure the accuracy of control, sensors such as pressure sensors and displacement sensors can be added to the system to monitor the actual movement state of the airbag. The sensor data is fed back to the main control board in real time, and the software adjusts the control signals based on this data to achieve closed-loop control and improve the stability and accuracy of the system. Before actual application, the entire system needs to be tested and calibrated to ensure that the values set by the software match the actual movement frequency of the airbag. Through multiple tests and adjustments, an accurate control model can be established so that the values set by the software can be accurately converted into the movement frequency of the airbag.

[0036] Generally speaking, through a simple mechanical structure and electrical control, the bionic cardiopulmonary motion simulation device of the present utility model realizes a highly realistic simulation of the undulating motion of the human cardiopulmonary. Among them, the human simulation cavity 1 serves as the housing of the entire device, providing stable support and protection; the battery 2 provides power for the device; the undulating motion simulator 3 is the core component, simulating the undulating motion of the cardiopulmonary through the inflation and deflation of the airbag 31; the undulating plate 32 directly presents the motion state of the cardiopulmonary; the air pump 4 serves as the power source, driving the airbag 31 to perform inflation and deflation actions. These components work together, enabling the device to realistically simulate cardiopulmonary motion and providing a powerful tool for medical education and research.

[0037] Finally, it should be noted that the electronic components in components such as the air pump 4 and the battery 2 in this embodiment are all common standard components or components known to those skilled in the art. Their structures and principles can be learned through technical manuals by those skilled in the art or obtained through conventional experimental methods. At the idle places of this device, connect all the above electrical components through wires respectively. The specific connection means should refer to the working sequence of each electrical component in the above working principle to complete the electrical connection, which is all well-known technology in the art.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present utility model, which are not used to limit the present utility model.
