Problems solved by technology

[0005] The present invention has the following advantages and effects: because a transparent bottle body is used for the above-mentioned overall arrangement, air can be supplied or automatically removed through the main pipe outside the bottle body during use, so that the two balloons can be inflated and contracted, which can reflect lung respiration. Phenomena, so that students can intuitively understand the phenomenon of lung activity, so that they can better grasp the knowledge, solve the problem that can only be expressed through words and languages, which is not conducive to improving the level of knowledge, simple and scientific

Abstract

The invention provides a dynamic teaching tool for pulmonary respiration. After a main pipe is inserted at a bottle plug of a transparent bottle, the main pipe is divided into two branch pipes, and the ends of the two branch pipes are respectively provided with balloons. In use, the main pipe can be used for air supply or air discharging, so as to enable the two balloons to be expanded or shrunk.Therefore, the pulmonary activity demonstration states of expanding and shrinking can be observed outside a transparent bottle.

Description

technical field [0001] The invention relates to a teaching aid, in particular to a dynamic teaching aid of lung breathing. Background technique [0002] Lung respiration is a state of expansion and contraction. Since the lungs are inside the human body, it is impossible to really observe and understand the respiration state during teaching. It can only be expressed through words and languages, which is not conducive to students' intuitive understanding and mastery of the dynamic knowledge of lung respiration. Contents of the invention [0003] The object of the present invention is to provide a dynamic teaching aid for lung breathing, which can intuitively observe and understand the dynamic state of lung breathing, and is beneficial for students to better and faster grasp the knowledge of lung breathing. [0004] The present invention includes a transparent bottle body, and the adopted technical scheme is that the lung breathing dynamic teaching aid penetrates into the mai...
