Pulmonary respiration motion model teaching tool

Abstract

The invention discloses a pulmonary respiration motion model teaching tool, which comprises a top cover, a display bottle, a reserve hole and a magnifying glass; a rubber plug is installed in an inletat the upper part of the top cover, and a simulation air balloon is arranged in the display bottle, the lower part of the simulation air balloon is connected with an elastic cloth, the lower part ofthe outer part of the display bottle is connected with a connecting pillar on the bottom plate through a connecting sleeve, the front surface of the vertical plate is provided with a buckle slot, anda puncture hole is reserved on the vertical hole; the reserve hole is arranged on the bottom plate, and the outside of the reserve hole is reserved with an insert slot; the magnifying glass is connected with a connecting block through an adjusting soft rod. According to the pulmonary respiration motion model teaching tool, the elastic cloth is bonded to the lower part of the simulation air balloon, the simulation air balloon plays a role of lung; the elastic cloth is existed as a thoracic cavity; when the simulation air balloon fills air or discharges air, the elastic cloth is correspondinglychanged along with it, thus a learner can more directly and vividly learn about the lung breathing motion.

Description

technical field [0001] The invention relates to the technical field of model teaching aids, in particular to a lung breathing exercise model teaching aid. Background technique [0002] The lung is an organ of the human body, which mainly plays the role of breathing. In biology, human body research is indispensable. This kind of research requires a vivid understanding of human organs and main operating dynamics. The importance of model teaching aids is not high. It goes without saying that the lungs mainly do breathing exercises, but most teaching aids for lung breathing exercise models are inconvenient to disassemble and install, and because of the small size of the simulation devices, far away learners cannot see clearly. In view of the above problems, an innovative design is carried out on the basis of the original teaching aids of lung breathing exercise model. Contents of the invention [0003] The purpose of the present invention is to provide a lung breathing exerci...
