Description

Technical Field

[0001] The utility model relates to the technical field of educational tools, in particular to a novel fetal heart teaching model with a detachable and reconfigurable structure. Background Art

[0002] Currently, ultrasound examinations can detect fetal abnormalities as early as possible. Prenatal fetal ultrasound examinations can rule out the possibility of congenital heart disease in the fetus. Fetal cardiac color Doppler ultrasound examinations can make early diagnoses of serious congenital heart diseases such as single ventricle, great vessel anomalies, atrioventricular valve malformations, aortic atresia, and pulmonary atresia. The ultrasound physician's proficiency in the structure and ultrasound characteristics of the fetal heart and great vessels is a prerequisite for ensuring the accuracy of fetal ultrasound examination results. Traditional teaching relies on text descriptions and flat illustrations in books, which have poor teaching effects and are difficult to understand and master. At present, there is a lack of suitable ultrasound teaching tools for ultrasound physicians, prenatal diagnosis and treatment doctors, pediatric cardiac surgeons, and medical students. There is an urgent need for a realistic, stereoscopic, intuitive, three-dimensional fetal heart and great vessel ultrasound teaching technology solution.

[0003] For example, the fetal heart and great blood vessel ultrasound teaching model disclosed in Chinese patent CN211349868U, although it is convenient for observers to learn and study the fetal heart structure, cannot achieve specific scoring of the fetal heart structure practice, cannot provide an intuitive experience of the assembly process, and lacks intelligent prompt function. For example, it cannot remind students to correct incorrect assembly, which affects the teaching effect.

[0004] Existing fetal heart teaching tools still have the following problems:

[0005] Lack of detachable and reassembleable design: Traditional models are usually integral structures that cannot be disassembled or reassembled. Students can only learn the anatomical characteristics of the heart through external observation, and it is difficult to carry out more in-depth hands-on operations and interactive experiences.

[0006] Inconvenient operation and low teaching efficiency: The existing models are not convenient to use and carry, and lack intelligent prompt functions. For example, when incorrect assembly occurs, students cannot be reminded to correct it, which affects the teaching effect.

[0007] The present invention is designed to solve the common problems in this field such as the inability to intuitively correct the fetal heart, the inability to dynamically grasp the specific structural layout of the heart, poor teaching results and poor assembly experience. Utility Model Content

[0008] The purpose of the utility model is to address the current deficiencies and propose a new fetal heart teaching model with a detachable and reconfigurable structure.

[0009] In order to overcome the deficiencies of the prior art, the present invention adopts the following technical solutions:

[0010] A novel detachable and reconfigurable fetal heart teaching model includes a simulated fetal heart module comprising a plurality of fetal heart components connected sequentially from the heart base toward the heart apex. The connection plane between two adjacent fetal heart components is a standard fetal heart ultrasound section, and the connection between the two adjacent fetal heart components is a mirror image structure. The fetal heart teaching model also includes a placement seat, a magnetic component, a connecting component, and an indicator component. The placement seat is provided with a receiving cavity for the placement of the fetal heart components. The connecting component is provided along the main body wall of each sequentially connected fetal heart component. When two adjacent fetal heart assemblies are connected, the connecting components provided on the adjacent fetal heart components connect to form a conductive path, triggering the indicator component to emit light and buzzer prompts.

[0011] The magnetic components are respectively arranged on the placement seat and the fetal heart component, and the fetal heart components and the fetal heart component and the placement seat are detachably adsorbed to each other.

[0012] Optionally, the connecting member includes a power supply and connecting wires adapted to the fetal heart assembly, the connecting wires being arranged on the fetal heart assembly and sequentially arranged along the assembly order of the fetal heart assembly;

[0013] When two adjacent fetal heart assemblies are correctly installed, the two adjacent fetal heart assemblies form a conductive channel.

[0014] Optionally, the connecting wires arranged on the main body wall of the fetal heart component are flush with each other.

[0015] Optionally, the indicating component includes a display area, and an indicator light and a buzzer arranged in the display area, and the buzzer and the indicator light are detachably connected to the connecting wire and the power supply and contact each other to form a closed loop.

[0016] Optionally, the fetal heart components include a left ventricular heart component, a right ventricular heart component, a left atrial heart component, a right atrial heart component, a mitral valve heart component, a tricuspid valve heart component, a ventricular septum heart component, an atrial septum heart component, and a foramen ovale heart component.

[0017] Optionally, the capacity of the accommodating cavity is adapted to the fetal heart component.

[0018] Optionally, the connecting wire is made of conductive metal material.

[0019] Optionally, the contact end faces of two adjacent assembled fetal heart components are magnetically opposite.

[0020] The beneficial effects achieved by the utility model are:

[0021] 1. Through the magnetic adsorption positioning function, the placement base can help users place the fetal heart component in the correct position, avoiding incorrect connections caused by improper operation and improving the assembly accuracy of the teaching model.

[0022] 2. The magnetic components physically connect the modules, while the connecting components establish the electrical pathway. These components work together to ensure that the modules are properly attached and the electrical pathway is connected smoothly, triggering the indicator function to provide a prompt of the assembly status. This allows the user to intuitively view the structural composition of the fetal heart, providing a dynamic understanding of the heart's specific structural layout and a high-quality assembly experience.

[0023] 3. This teaching model achieves a comprehensive effect of stable modular support, quick connection, intelligent feedback, and interactive teaching, enhancing assembly convenience, model functionality, and teaching interest. These combined efforts ensure the stability and accuracy of the fetal heart teaching model during operation and demonstration, effectively improving the shortcomings of traditional teaching models.

When two adjacent fetal heart assemblies are connected, the connecting components provided on the adjacent fetal heart components connect to form a conductive path, and the indicator component is triggered to emit light and buzzer prompts.

[0033] In this embodiment, the simulated fetal heart module further includes a microprocessor, which is controllably connected to the indicator member and the connecting member. The microprocessor controls the indicator member and the connecting member based on the microprocessor, so that after assembly is completed, sound and light prompts can be provided, thereby improving the reliability of the operation convenience and teaching efficiency of the entire teaching model.

[0034] The magnetic components are respectively arranged on the placement seat and the fetal heart component, and the fetal heart components and the fetal heart component and the placement seat are detachably adsorbed to each other.

[0035] Optionally, the fetal heart components include a left ventricular heart component 8, a right ventricular heart component 6, a left atrial heart component 1, a right atrial heart component 2, a mitral valve heart component 5, a tricuspid valve heart component 4, a ventricular septum heart component 7, an atrial septum heart component, and a foramen ovale heart component 3.

[0036] In this embodiment, the foramen ovale cardiac component 3 is a portion of the cardiac component of the atrial septum, but not the entire atrial septum;

[0037] Optionally, the connecting member includes a power supply and connecting wires adapted to the fetal heart assembly, the connecting wires being arranged on the fetal heart assembly and sequentially arranged along the assembly order of the fetal heart assembly;

[0038] When two adjacent fetal heart assemblies are correctly installed, the two adjacent fetal heart assemblies form a conductive channel.

[0039] The connecting member further includes an α contact head, a β contact head, an α contact wire, and a β contact wire, one end of the α contact wire is connected to the α contact head, the other end of the α contact wire is connected to one end of the power supply, one end of the β contact wire is connected to the β contact head, and the other end of the β contact wire is connected to the other end of the power supply;

[0041] Optionally, the connecting wires arranged on the main body wall of the fetal heart component are flush with each other.

[0042] like Figure 3 and Figure 4 As shown, when the fetal heart components are correctly installed, the two fetal heart components are connected under the mutual adsorption of the magnetic components, so that the connecting wires contact each other to form a conductive channel.

[0043] Optionally, the indicating component includes a display area, and an indicator light 12 and a buzzer 11 arranged in the real area. The buzzer 11 and the indicator light 12 are detachably connected to the connecting wire and the power supply and are in contact with each other to form a closed loop.

[0044] like Figure 1As shown by the bold lines in FIG, the connection of the closed loop is: one end of the power supply → first contact part → right atrial heart component 2 → mitral valve heart component 5 → right ventricular heart component 6 → interventricular septum heart component 7 → left ventricle → right atrium → interventricular septum heart component → first contact part → indicator member → the other end of the power supply;

[0045] In addition, the fetal heart component further includes a front heart component 10, which covers the left atrium and the right atrium to form a whole fetal heart.

[0046] Optionally, the capacity of the accommodating cavity is adapted to the fetal heart components, so that all heart components can be assembled and installed in the accommodating cavity.

[0048] In this embodiment, a magnetic member 9 is provided on each of the fetal heart components, and the magnetic seat is provided on the contact end surface of the placement seat and the heart component, thereby adsorbing the assembled fetal heart component on the end surface of the placement seat to prevent the assembled fetal heart component from falling off the placement seat;

[0049] At the same time, if Figure 3 and Figure 4 As shown, the magnetic component is also provided on the two adjacently assembled fetal heart components so that the fetal heart components are attracted to each other.

[0051] Optionally, the connecting wires are made of conductive metal material, so that each fetal heart can be connected.

[0052] The magnetic components are responsible for the physical connection of the modules, while the connecting components are used to establish the electrical path. The two work together to ensure that the modules are properly adsorbed and the electrical path is smoothly connected, thereby triggering the indicator function to provide a prompt of the assembly status, ensuring that the user can intuitively view the structural composition of the fetal heart, with the advantages of dynamically understanding the specific structural layout of the heart and a high assembly experience.

[0053] Optionally, the contact end faces of two adjacent assembled fetal heart components are magnetically opposite, thereby splicing the two fetal heart components together.

[0054] In this embodiment, the connecting component triggers the indication function, so that the model has interactive feedback capabilities, which increases the interest of teaching and allows users to receive immediate instructions during operation, thereby increasing their understanding and memory of the fetal heart structure.
