(1) This model comprises only a plastic bottle, balloons, and a rubber band; it can therefore be easily made for all the students.
(2) The red heart-shaped balloon represents the lung, the pink dome-shaped balloon at the bottom represents the diaphragm, and the plastic bottle represents the thorax.(3) Students with total blindness can understand the internal structure of the plastic bottle by inserting the hand into the bottle, from which the pink balloon (the diaphragm) has been removed, and touching the balloon (the lung) inside the bottle.(4) Make a hole in a plastic bottle and cover the hole with vinyl tape. The sealed bottle represents respiratory movement in a normal state and the unsealed bottle represents that in pneumothorax.(5) A plastic bottle with a hole, representing a state of pneumothorax.
| 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 anatomical spatial relationship of the thorax, diaphragm, and lung • the changes in intrathoracic pressure along with the morphological changes in the diaphragm • the morphological changes in the lung along with the changes in intrathoracic pressure • the morphological changes in the lung in the normal state and pneumothorax. |
| Considerations for disability characteristics |
• Understanding the mechanism of negative intrathoracic pressure is difficult regardless of the presence or absence and degree of visual impairment. However, understanding the changes in intrathoracic pressure and lung morphology along with the morphological changes in the diaphragm, as a series of events, is very important in learning physiology. • The plastic bottle is analogous to the thorax, the balloon inside the bottle to the lung, and the balloon at the bottom to the diaphragm. This respiratory movement model enables students to observe the inflation of the lung by pulling the diaphragm downward (equivalent to making the muscles contract). • A transparent plastic bottle enables students to visually observe the lung inside the thorax. If visual observation is not possible, show students the model with the bottom balloon removed at first, make them understand the internal structure, and then have them observe the complete respiratory movement model. In spite of visual observation of the inside of the bottle not being possible, students can understand the in- and out-flow of air by placing the cheek at the mouth of the bottle or putting a finger into the bottle. This model enables students to imagine the air flow into or out of the lung without relying on vision. • A hole was made in a plastic bottle to create the state of pneumothorax, which enables students to observe how the lung’s movement differs from that in the normal state. • This model can be easily made and therefore it can be distributed to all students. We prepared the model for all students so that they were able to use the model whenever they wanted to. |
| Expected effects and results |
Students will be able to understand: • the anatomical spatial relationship of the thorax, diaphragm, and lung. • the changes in intrathoracic pressure and lung morphology along with the morphological changes in the diaphragm as a series of events • the morphological differences in the lung between the normal state and pneumothorax. |
| How to use |
(1) Explain to students the anatomical spatial relationship of each part of the model (thorax, diaphragm, and lung). (2) Observe how the lung changes when pulling the diaphragm downward. (3) Peel off the tape from the plastic bottle to create a state of pneumothorax. (4) As with (2), observe how the lung in the state of pneumothorax changes when pulling the diaphragm downward. |
