Electrical Human Respiratory Model

Electrical Human Respiratory Model

This device demonstrates physiological mechanism of human respiratory movement.

Components

Electrical human respiratory model consists of engineering plastic rib, intercostales externi, intercostales interni, sternum, diaphragm, trachea and lungs models, etc.

Usage

1 power supply: AC 220V-50Hz, current: 1.0A. (Schematic circuit as above)

2 press power switch 

3 Dynamic demonstrations:

Inspiration: rib rises and diaphragm down, thorax and lungs expand, and light near lungs and trachea turns brighter.

Expiration: rib down and diaphragm rise, thorax and lungs narrow, and light near lungs and trachea turns weaken.

Cautious

1 keeps the model upright

2 store in a cool and dry place to avoid sunshine.

3 wipe the product with wet cloth, forbid to scrub it with chemicals or corrosive liquid.
