Description

Technical Field

[0001] This utility model relates to the field of medical teaching simulation equipment technology, and in particular to a simulated human chest pressure feedback component. Background Technology

[0002] In medical education and first aid training, skills training involving chest compressions, such as cardiopulmonary resuscitation (CPR), is crucial. However, traditional mannequin chest structures often lack precise pressure feedback mechanisms, making it difficult for trainees to accurately grasp key parameters such as compression force, depth, and frequency. This not only affects training effectiveness but also hinders trainees from rapidly improving their first aid skills.

[0003] Currently, existing mannequin chest pressure feedback components have the problem of small feedback range, which makes it impossible to fully and accurately sense the pressure at different positions of the chest. When trainees press different positions of the chest, the pressure feedback component cannot directly reflect the pressure at different positions, resulting in low efficiency. Therefore, it is urgent to design a mannequin chest pressure feedback component to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a simulated human chest pressure feedback component. Its advantages lie in the ability to flexibly adjust the positions of components such as pressure sensors according to actual needs, adapting to different simulation scenarios and usage requirements, thus increasing the component's applicability and flexibility, and improving work efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A simulated human chest pressure feedback component includes a simulated human body, a thoracic cavity at the chest of the simulated human body, a bionic skin fixedly installed on the top of the inner wall of the thoracic cavity, a device frame fixedly installed on the bottom of the inner wall of the thoracic cavity, guide grooves on both sides of the top of the device frame, a drive frame movable on the inner wall of the guide groove, a position adjustment component for driving the drive frame to move laterally on the device frame, a support plate sleeved on the top of the drive frame, a pressure sensor fixedly installed on the top of the support plate, a support platform fixedly installed on the top of the pressure sensor, and a protective pad installed on the top of the support platform;

[0007] Buffer components are provided at the bottom of the support plate and the top of the equipment frame.

[0008] The above technical solutions enable the pressure feedback component to directly feed back pressure from different locations, increasing the component's applicability and flexibility, and improving work efficiency.

[0009] The present invention is further configured such that both ends of the top of the support plate are provided with connecting ports, and the top ends of both ends of the drive frame pass through the interior of the connecting ports.

[0010] The above technical solutions facilitate the movement of the support plate on the drive frame.

[0011] The present invention is further configured such that the bottom surface of the bionic leather is flush with the bottom surface, and the protective pad is attached to the bottom surface of the bionic leather.

[0012] Through the above technical solutions, the bionic skin simulates the texture of human chest skin. Combined with protective pads, it can protect components such as pressure sensors from direct external impacts, making the simulated human chest close to the real human body in appearance and feel.

[0013] The present invention is further configured such that the position adjustment component includes a threaded rod rotatably connected to the inner wall of the equipment frame, and a threaded hole adapted to the outer wall of the threaded rod is provided at the middle position of the drive frame. A first mounting groove is provided on one side of the equipment frame, and a forward and reverse motor is fixedly installed on the inner wall of the first mounting groove. A first bevel gear located inside the equipment frame is fixedly installed on the output shaft of the forward and reverse motor. A second bevel gear is fixedly installed at one end of the threaded rod, and the second bevel gear meshes with the first bevel gear.

[0014] The above technical solutions allow for flexible adjustment of the positions of components such as pressure sensors according to actual needs.

[0015] The present invention is further configured such that a second mounting groove is provided on one side of the device frame, and a signal processing module is fixedly installed on the inner wall of the second mounting groove. The signal processing module is electrically connected to the pressure sensor and consists of a signal amplification circuit, a filtering circuit, and a microprocessor.

[0016] The present invention is further configured such that the signal processing module is electrically connected to the control host, and the control host is electrically connected to the forward and reverse motor and the pressure sensor.

[0017] The above technical solutions facilitate rapid feedback of pressure information.

[0018] The present invention is further configured such that the buffer assembly includes an elastic buffer layer fixedly installed on the top of the equipment frame, and fixed frames are fixedly installed on both sides of the bottom of the support plate. The inner walls of the fixed frames are rotatably connected to sliding rollers, which are attached to the top surface of the elastic buffer layer.

[0019] The present invention is further configured such that the elastic buffer layer is composed of a rubber grating plate, a silicone sleeve and a protective skin from the inside out, and silicone filler is provided in the gaps of the rubber grating plate.

[0020] The above technical solution simulates the elastic properties of human chest muscles and fat. When pressure is felt, the elastic buffer layer deforms and absorbs some of the pressure, making the pressure feedback closer to the feeling of a real human chest.

[0021] The beneficial effects of this utility model are as follows:

[0022] This invention uses a pressure sensor to accurately sense the pressure on the chest and transmits the pressure signal to a signal processing module. The signal is then analyzed and processed by the control host, providing precise data support for simulating chest pressure feedback. This helps to more realistically simulate the human chest's response to pressure and can be applied to medical training, rehabilitation training, and other scenarios, helping users better master the correct operating force.

[0023] This invention, through the setting of a position adjustment component, allows the position of components such as pressure sensors to be flexibly adjusted according to actual needs, adapting to different simulation situations and usage requirements. It also enables the pressure feedback component to directly feed back pressure at different positions, increasing the applicability and flexibility of the component and improving work efficiency.

[0024] In this invention, the bionic skin simulates the texture of human chest skin, and the protective pad is attached to the bottom surface of the bionic skin. On the one hand, it can protect components such as pressure sensors from direct external impacts and prevent them from being damaged. On the other hand, the combination of bionic skin and protective pad makes the simulated human chest close to the real human body in appearance and feel, improving the realism of the simulation and the user experience.

[0025] The elastic buffer layer of this invention is made of a material with certain elasticity and toughness, which can simulate the elastic characteristics of human chest muscles and fat tissues. When pressure is felt, the elastic buffer layer will deform and absorb part of the pressure, making the pressure feedback closer to the feeling of a real human chest and enhancing the simulation effect.

[0032] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0033] Reference Figures 1-5 This utility model provides a simulated human chest pressure feedback component, including a simulated human body 1. A thoracic cavity 5 is provided at the chest of the simulated human body 1, and a bionic skin 10 is fixedly installed on the top of the inner wall of the thoracic cavity 5. A device frame 2 is fixedly installed on the bottom of the inner wall of the thoracic cavity 5. Guide grooves 14 are provided on both sides of the top of the device frame 2, and a drive frame 6 is movably mounted on the inner wall of the guide grooves 14. A position adjustment component 4 for driving the drive frame 6 to move laterally is provided on the device frame 2. The position adjustment component 4 includes a threaded rod 405 rotatably connected to the inner wall of the device frame 2, and a threaded hole adapted to the outer wall of the threaded rod 405 is provided at the middle position of the drive frame 6. A first mounting groove 401 is provided on one side of the device frame 2, and a forward / reverse motor 402 is fixedly installed on the inner wall of the first mounting groove 401. The output shaft of the forward / reverse motor 402 is fixedly installed on a first mounting groove located inside the device frame 2. A first bevel gear 403 and a threaded rod 405 are fixedly mounted on one end of a second bevel gear 404, which meshes with the first bevel gear 403. A support plate 7 is fitted on the top of the drive frame 6, and a pressure sensor 8 is fixedly mounted on the top of the support plate 7. A support platform 9 is fixedly mounted on the top of the pressure sensor 8, and a protective pad 11 is installed on the top of the support platform 9. Both ends of the top of the support plate 7 have through-holes 16, and the top of both ends of the drive frame 6 pass through the interior of the through-holes 16. The bottom surface of the bionic skin 10 is flush with the bottom surface of the bionic skin 10, and the protective pad 11 is attached to the bottom surface of the bionic skin 10. The position adjustment component 4 allows the position of the pressure sensor 8 and other components to be flexibly adjusted according to actual needs, and the pressure feedback component can directly feed back the pressure at different positions, increasing the applicability and flexibility of the component and improving work efficiency.

[0034] A buffer assembly is provided at the bottom of the support plate 7 and the top of the equipment frame 2. The buffer assembly includes an elastic buffer layer 12 fixedly installed on the top of the equipment frame 2. Fixed frames 15 are fixedly installed on both sides of the bottom of the support plate 7. The inner walls of the fixed frames 15 are rotatably connected to the sliding rollers 17. The sliding rollers 17 are attached to the top surface of the elastic buffer layer 12. The elastic buffer layer 12 is composed of a rubber grid plate 1203, a silicone sleeve 1202 and a protective skin 1201 from the inside out. Silicone filler 1204 is provided in the gaps of the rubber grid plate 1203. It can simulate the elastic characteristics of human chest muscles and fat tissues. When pressure is felt, the elastic buffer layer 12 will deform under the squeezing action of the sliding rollers 17, absorbing part of the pressure, making the pressure feedback closer to the feeling of a real human chest and enhancing the simulation effect.

[0035] To ensure rapid feedback, refer to Figure 1 and Figure 5 A second mounting slot 13 is provided on one side of the equipment frame 2, and a signal processing module 3 is fixedly installed on the inner wall of the second mounting slot 13. The signal processing module 3 is electrically connected to the pressure sensor 8. The signal processing module 3 consists of a signal amplification circuit, a filtering circuit, and a microprocessor. The signal processing module 3 is electrically connected to the control host, and the control host is electrically connected to the forward and reverse motor 402 and the pressure sensor 8. The pressure sensor 8 converts the pressure signal it senses into an electrical signal and transmits it to the signal processing module 3. The weak electrical signal transmitted from the pressure sensor 8 is amplified by the signal amplification circuit, and the interference noise in the signal is removed by the filtering circuit. The processed signal is analyzed and processed by the microprocessor to obtain accurate pressure data information, and finally, this information is transmitted to the control host.

[0036] Working principle: When the simulated human chest is pressurized by the actuator, the pressure is transmitted to the support platform 9 through the bionic skin 10 and protective pad 11, thereby causing pressure sensor 8 to be subjected to pressure. Pressure sensor 8 converts the sensed pressure signal into an electrical signal and transmits it to signal processing module 3. The signal amplification circuit in signal processing module 3 amplifies the weak electrical signal from pressure sensor 8, while the filtering circuit removes interference noise from the signal. The processed signal is analyzed and processed by the microprocessor to obtain accurate pressure data information, and finally, this information is transmitted to the control host.

[0037] When the simulated human chest is subjected to pressure, the bionic skin 10 simulates the texture of human chest skin. The protective pad 11 is attached to the bottom surface of the bionic skin 10, which can protect the pressure sensor 8 and other components, preventing damage from direct external impact. It also makes the simulated human chest close to the real human body in appearance and feel. In addition, the buffer component and elastic buffer layer 12 simulate the elastic properties of human chest muscles and fat tissues. When pressure is felt, the elastic buffer layer 12 will deform and absorb part of the pressure, making the pressure feedback closer to the feeling of the real human chest.

[0038] When it is necessary to sense the pressure at different positions on the chest, the forward and reverse motor 402 is started. The output shaft of the forward and reverse motor 402 drives the first bevel gear 403 to rotate. The first bevel gear 403 meshes with the second bevel gear 404, thereby driving the threaded rod 405 to rotate. This causes the drive frame 6 to move laterally in the guide groove 14, which in turn moves the support plate 7, pressure sensor 8 and other components to the appropriate position, so as to achieve precise adjustment of the position of the pressure sensor 8.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
