Embodiment Construction

[0023] In order to clearly illustrate the technical features of this solution, the specific implementation of this solution will be described below in conjunction with the accompanying drawings.

[0024] Such as figure 1 and figure 2 As shown, the human breathing demonstration apparatus is a human breathing demonstration apparatus including a simulated chest cavity, a simulated lung and a simulated skeleton.

[0025] The simulated chest cavity includes a shell-shaped cover body 1 of transparent material, the cover body 1 is a cylindrical shape with an open bottom, and a rubber film 2 representing the diaphragm is sealed on the cover body opening; the cover body 1 and the rubber film 2 form a closed space. The cavity represents the chest cavity of the human body. In addition, a pull hook 7 is installed in the middle of the rubber film 2 , the pull hook 7 penetrates the rubber film up and down and protrudes from both ends, and the two ends of the pull hook have hooks.

Abstract

The invention provides a human breathing demonstration instrument, which comprises a simulative thorax, simulative lungs and a simulative skeleton; the simulative skeleton is arranged in the simulative thorax, and comprises a vertical rod as the spinal column and curved rods as the ribs, the curved rods are curved, one end of each of each pair of curved rods is articulated with the vertical rod through a bolt, and the other ends of each pair of curved rods are articulated with a connecting rod as the sternum through bolts; the connecting rod is vertically arranged, the lower end of the connecting rod is connected with a restoring spring, the other end of the restoring spring is connected with a housing, and the restoring spring can downwardly pull the connecting rod; the upper end of the connecting rod is connected with a string, and the string passes through a pulley arranged on a cross rod, and is connected with a hook. The human breathing demonstration instrument not only can demonstrate the entry of the air into the lungs, the expansion and contraction of the lungs, the motion of the diaphragms and the expansion and contraction of the thorax when the human body breathes, but also can demonstrate the motion of the ribs, the sternum and other thoracic bones.

Description

technical field [0001] The invention relates to a demonstration teaching aid for physiological teaching, in particular to a human breathing demonstration instrument. Background technique [0002] In biology teaching, the application of various teaching instruments can allow students to receive knowledge intuitively and emotionally, making teaching no longer boring. The principle of human respiration is a very important knowledge point in middle school biology teaching. If the process can be demonstrated with teaching instruments, students' understanding of this part of knowledge will be more intuitive. [0003] The technology closest to the present invention is a Chinese invention patent with the patent number 200820024495.1 and the date of announcement is March 4, 2009. The name is a simple demonstration device for the principle of human respiration. This invention provides a simple demonstration device for the principle of human respiration, which belongs to the biolog...
