Description

Technical Field

[0001] The utility model relates to the technical field of medical teaching models, in particular to a human heart teaching model. Background Art

[0002] The heart teaching model is a teaching and learning tool designed to help students and medical staff understand and master the structure and function of the heart. The design and production of the heart teaching model aims to promote students' mastery of scientific knowledge and cultivate their research ability and scientific spirit.

[0003] The existing technology has the following deficiencies: The prior art, "A detachable heart model for teaching and display," with publication number CN109686213B, "includes simulated lungs, a simulated human body, a left heart model, and a right heart model. The left heart model includes a left ventricle model, an aorta model, a left atrium model, and a pulmonary vein model; the right heart model includes a right ventricle model, superior and inferior vena cava models, a right atrium model, and a pulmonary artery model. One side of the left heart model is hingedly connected to one side of the right heart model by a connector. The connector includes a left heart connecting shaft, a right heart connecting shaft, and a middle connecting shaft connected between the left and right heart connecting shafts. Light strips are installed in the heart model, simulated lungs, and simulated human body according to the order of blood circulation."

[0004] The above structure intuitively displays the order of blood flow in the heart by changing the arrangement of the heart structure according to the process of blood circulation. However, the structure does not provide a detailed display of the opening and closing changes of the heart valve position, which is not conducive to valve structure learning. There is also no improvement to the external structure. If the model is touched and rubbed by human hands for a long time, the exterior will cause discoloration, which will not only mislead students but also reduce its service life. Summary of the Invention

[0005] In view of the deficiencies of the existing technology, the present invention provides a human heart teaching model, which solves the current problems of lack of detailed display of heart valve structure and lack of anti-wear treatment of the outer coating.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a human heart teaching model, comprising a model body, a base, and a connecting frame, wherein the base is arranged below the model body, and the connecting frame is arranged between the model body and the base; a right atrium is arranged inside the right side of the model body, a right ventricle is arranged below the right atrium, and a tricuspid valve is arranged between the right atrium and the right ventricle; a left atrium is arranged inside the other side of the model body, a left ventricle is arranged below the left atrium, and a mitral valve is arranged between the left ventricle and the left atrium;

[0007] An aorta component is provided in the middle of the model body;

[0008] The aortic component includes a pulmonary trunk, a pulmonary valve, and an aortic valve. The pulmonary trunk is fixedly connected to the front end of the aortic component, the pulmonary valve is plugged into the lower end of the pulmonary trunk, and the aortic valve is plugged into the side end of the pulmonary trunk.

[0009] As an optimal technical solution of the present invention, the model body also includes an anti-wear coating and an epoxy paint coating. The anti-wear coating is fixedly installed on the outer end of the model body, and the epoxy paint coating is applied to the outer surface of the model body.

[0010] As a preferred technical solution of the present invention, the main material of the anti-wear coating is specifically silicon carbide, boron oxide, and resin, and is evenly covered between the model body and the epoxy paint coating surface.

[0011] As a preferred technical solution of the present invention, the pulmonary artery trunk is an irregular tubular structure as a whole, and notches are provided at the bottom and one side of the aortic valve.

[0012] As a preferred technical solution of the present invention, the size of the pulmonary valve and the aortic valve is the same as the notch on the outside of the pulmonary trunk, and the color is different from the main structure of the pulmonary trunk. In this solution, the pulmonary trunk is preferably red and the pulmonary valve and the aortic valve are white.

[0013] As a preferred technical solution of the present invention, the model body is divided into two parts, one of which contains all the structures of the human heart, and the inner side section of the other part is a plane, and the two parts are connected by a snap-fit connection.

[0014] As an optimal technical solution of the present utility model, the above.

[0015] Compared with the existing technology, the present invention provides a human heart teaching model with the following beneficial effects:

[0016] The human heart teaching model is provided with an aortic component, a pulmonary trunk, a pulmonary valve and an aortic valve. When the operator uses the model to display and study the parts of the human heart, the model body can be split into two parts to expose the cross-sectional state of the middle part. At this time, the state displayed by the model body is a complete internal structure diagram. At this time, the operator can intuitively distinguish the internal structure of the heart. Since the pulmonary valve and the aortic valve are connected to the pulmonary trunk by snap-fitting, the operator can directly remove the pulmonary valve and the aortic valve to expose the internal circulation of the pulmonary trunk, and can also intuitively show the difference between the pulmonary valve and the aortic valve in the open or closed state. By coating the outside of the model body with epoxy paint, the wear of the model body due to long-term touch and friction can be reduced, the service life of the structure can be extended, and the wear of the external paint can be prevented to prevent misunderstandings of the students.

[0025] The aortic component 10 includes a pulmonary trunk 1001, a pulmonary valve 1002, and an aortic valve 1003. The pulmonary trunk 1001 is fixedly connected to the front end of the aortic component 10, the pulmonary valve 1002 is inserted into the lower end of the pulmonary trunk 1001, and the aortic valve 1003 is inserted into the side end of the pulmonary trunk 1001.

The anti-wear coating 101 is fixedly mounted on the outer end of the model body 1, and the epoxy paint coating 102 is coated on the outer surface of the model body 1. The main material of the anti-wear coating 101 is specifically silicon carbide, boron oxide, and resin, and is evenly covered between the model body 1 and the epoxy paint coating 102.

[0027] Specifically, the uniform outer coverage of the anti-wear coating 101 and the epoxy paint coating 102 can effectively ensure that the model body 1 can protect its inner body from being worn when touched by human hands;

[0028] In this embodiment, the pulmonary trunk 1001 is an overall irregular tubular structure, with notches formed at the bottom and on one side of the aortic valve 1003. The pulmonary valve 1002 and the aortic valve 1003 have the same size as the notches on the outside of the pulmonary trunk 1001, and are different in color from the main structure of the pulmonary trunk 1001. In this embodiment, the pulmonary trunk 1001 is preferably red, while the pulmonary valve 1002 and the aortic valve 1003 are preferably white.

[0029] Specifically, by setting the pulmonary trunk 1001, the pulmonary valve 1002 and the aortic valve 1003 in different colors, it can more effectively help students distinguish the valve structures and improve learning efficiency.

[0030] In this embodiment, the model body 1 is divided into two parts, one of which contains all the structures of the human heart, and the inner side section of the other part is a plane, and the two parts are connected by snap-fitting.

[0031] The working principle and usage process of the present invention are as follows: when the operator uses the model to display and study the human heart parts, the model body 1 can be split into two parts to expose the cross-sectional state of the middle part. At this time, the state displayed by the model body 1 is a complete internal structure diagram. At this time, the operator can intuitively distinguish the internal structure of the heart. Since the pulmonary valve 1002 and the aortic valve 1003 are both connected to the pulmonary trunk 1001 by snap-fitting, the operator can directly remove the pulmonary valve 1002 and the aortic valve 1003 to expose the internal circulation conditions of the pulmonary trunk 1001, and can also intuitively display the difference between the pulmonary valve 1002 and the aortic valve 1003 in the open or closed state.
