Lung Breathing Model, Diaphragm Movement Simulation Demonstrator, Biology Teaching Aids for Medical Student, Lab & Classroom Use
▶This instrument is composed of transparent plastic container, elastic rubber bottom, rubber stopper and lung lobe model. Size: bottom diameter 112* height 192mm
▶The transparent plastic inverted “Y”-shaped trachea is installed in the rubber stopper, and the trachea connects the two lung lobes.
▶Before the experiment, take off the rubber bottom first, and blow a little air into the lung lobes through the inverted "Y"-shaped trachea to make the lung lobes slightly swell, and then put the rubber bottom in, so that the transparent container forms a closed space, and the lung lobes are connected to the outside air .
▶During the experiment, pull down the drop in the middle of the rubber bottom, and you can see that the lung lobes are obviously inflated; loosen the bottom rubber, and the lung lobes return to slightly inflated; push up the rubber bottom, and the lung lobes shrink.
▶Use: According to the new junior high school biology textbook, let students understand the relationship between the change of chest cavity volume and the activity of diaphragm. Provides a versatile teaching tool that can be used in a variety of settings, such as classrooms.
