aortic valve / dorsal
mitral valve / pulmonary arterytricuspid valve / ventral
| Target | Students with visual impairment (the Physical Therapy Course of the Advanced Vocational Course) (≥ 18 years old) |
|---|---|
| Disability category | visual impairment |
| Teaching units / Applicable scenes | other acupuncture, moxibustion, manual therapy |
| Specific purposes |
Students will be able to understand: • the structure of cardiac valves • the anatomical spatial relationship of cardiac valves. |
| Considerations for disability characteristics |
• Most common cardiac models are three-dimensional structures and therefore the whole image of the heart can be easily understood. However, they can provide only fixed cross-sectional planes. In addition, their poorly contrasting colors often make it hard for students with visual impairment to clearly make out the details. • This cardiac model provides a transverse cross-section between the atrium and ventricle, which enables students to easily grasp the structure and anatomical spatial relationship of the four valves. The use of cloth with different colors and textures makes it easier for students with amblyopia (reduced vision) or total blindness to understand by sight and touch. • The aortic and pulmonary valves have a pocket-like structure. For easy understanding of the changes in the shape of the valves according to the direction of blood flow, the valves are made of soft cloth (felt). |
| Expected effects and results | After gaining an understanding of the structure of the heart using a conventional 3D cardiac model, students will be able to grasp the anatomical spatial relationship among the aortic and pulmonary valves and atrioventricular valves at the transverse level of the atrium and ventricle using this teaching model. Students will also be able to understand the structural difference between the aortic and pulmonary valves and atrioventricular valves. |
| How to use |
(1) Check the anatomical spatial relationship of cardiac parts, which can be recognized from their outer appearance, using a conventional 3D cardiac model. (2) Check the anatomical spatial relationship of the four valves on the transverse plane using the teaching model, which represents the cross section between the atrium and ventricle. (3) Understand the anatomical spatial relationship between the aortic and pulmonary valves and atrioventricular valves. (4) Check the structure of the aortic and pulmonary valves and atrioventricular valves by inserting a finger into the valves. (Note the pocket-like structure of the aortic and pulmonary valves, which prevents blood backflow.) |
