3D heart model

Abstract

A three-dimensional heart model includes a model body, which is V-shaped and has two opposing surfaces forming a first surface and a second surface. It comprises a left ventricular portion, a first hook portion, a right ventricular portion, a second hook portion, and a connecting portion. The left ventricular portion is located on the right side of the model body. The first hook portion is located above the left ventricular portion, with its opening facing the right side of the model body. The right ventricular portion is located on the left side of the model body. The second hook portion is located above the right ventricular portion, with its opening facing the left side of the model body. The first hook portion hooks onto the opening of the second hook portion from its second surface, causing the middle sections of the left and right ventricular portions to arch away from each other, forming a three-dimensional structure.

Claims

1. A three-dimensional heart model, comprising: The model body is V-shaped and has a first surface and a second surface on opposite sides. It includes: a left ventricular portion located on the right side of the model body; a first hook portion located above the left ventricular portion, with the opening of the first hook portion facing the right side of the model body; a right ventricular portion located on the left side of the model body; a second hook portion located above the right ventricular portion, with the opening of the second hook portion facing the left side of the model body; and a connecting portion located in the middle of the model body, connecting the left ventricular portion and the right ventricular portion. The first hook portion hooks the opening of the second hook portion from the second surface of the second hook portion, causing the left ventricular portion and the right ventricular portion to arch and form a three-dimensional structure.

2. The three-dimensional heart model as described in claim 1, wherein, The left ventricular portion has a first adhesive portion disposed on the first surface of the left ventricular portion and located on the side close to the right ventricular portion, and the right ventricular portion has a second adhesive portion disposed on the second surface of the right ventricular portion and located on the side close to the left ventricular portion; wherein the first adhesive portion and the second adhesive portion are bonded to each other by an adhesive.

3. The three-dimensional heart model as described in claim 1 further includes a pulmonary vein adhesive component; wherein, The left ventricular portion has a pulmonary vein adhesive portion disposed on the second surface of the left ventricular portion, for the pulmonary vein adhesive component to be adhered to the pulmonary vein adhesive portion by means of an adhesive.

4. The three-dimensional heart model as described in claim 1, wherein, The first face of the model body is provided with a cross-sectional view of the heart.

5. A three-dimensional heart model as described in claim 4, wherein, This cross-sectional diagram of the heart includes the cross-sectional shapes of the left atrium, right atrium, left ventricle, right ventricle, great vein, aorta, and pulmonary artery.

6. A three-dimensional heart model as described in claim 1, wherein, The second side of the model body features an illustration of a heart.

7. A three-dimensional heart model as described in claim 6, wherein, This diagram of the heart's appearance includes the external shapes of the left atrium, right atrium, left ventricle, right ventricle, great vein, aorta, and pulmonary artery.

8. The three-dimensional heart model as described in claim 1, wherein, The model body is formed by cutting a sheet-like substrate, which has: a cross-sectional view of the heart, viewed from the front of the human body, disposed on one side of the sheet-like substrate; and an external view of the heart, viewed from the back of the human body, disposed on the other side of the sheet-like substrate; wherein the outlines of the cross-sectional view and the external view of the heart are mirror-symmetrical, such that the outlines of the cross-sectional view and the external view of the heart overlap, and respectively correspond to the first and second sides of the model body.
