Abstract
The utility model discloses a diaphragm movement simulation teaching instrument for vividly demonstrating the respiratory movement principle of human body. The instrument comprises a transparent external housing provided with an elastic membrane at the bottom; the external housing and the elastic membrane enclose a hermetic cavity, in which a big pipeline is arranged; the upper end of the big pipeline extends out of the external housing and is communicated with the atmosphere; the lower end of the big pipeline is connected with two small branch pipelines, which are connected with a hermetic elastic membrane ball respectively; the elastic membrane is made of plastic and the elastic membrane ball is a rubber balloon; the external housing represents the thorax; the pipeline represents the trachea; two small branch pipelines represent two bronchi; two balloons represent the left and right lungs; the elastic membrane at the bottom of the external housing represents the diaphragm; and the cavity enclosed by the external housing and the membrane represents the thoracic cavity. The utility model has the advantages of vivid demonstration of respiratory movement principle of human body, simple structure, easy production, and good use value.
Description
Technical field
The utility model relates to a kind of instruments used for education, particularly a kind of simulation diaphram motion teaching appliance.
Background technology
At present, in the teaching about " occurring in the gas exchange in a lung " class in seven grades biological teaching materials, when explanation human body respiratory movement principle, teaching mode can adopt for the teacher intuitively without comparison, effort when so the teacher explains, the student is not easy to understand.
Summary of the invention
The utility model provides a kind of simulation diaphram motion instruments used for education that can vividly demonstrate the human body respiration motion principle.
The technical scheme that its technical matters that solves the utility model adopts, a kind of simulation diaphram motion teaching appliance, it comprises transparent outer cover, the flexible film in outer cover bottom, outer cover and its bottom elastic film surround sealed cavity, and large pipeline is arranged in the cavity, and the large pipeline upper end is stretched out outer cover and communicated with atmosphere, the large pipeline lower end is connected with two branch's small pipelines, and small pipeline is connected with the elastic film ball of sealing.
Described elastic film is a plastic sheeting, and the elastic film ball is a rubber balloon.
The beneficial effects of the utility model: outer cover is represented thorax, and large pipeline is represented tracheae, and two branch's small pipelines are represented bronchus, and two balloons are represented [, and the elastic film of outer cover bottom is represented diaphram, and the cavity that outer cover and bottom thin film surround is represented the thoracic cavity.Because the cavity in expression thoracic cavity seal, balloon communicates with atmosphere by large and small pipeline, and the air pressure in the balloon is consistent with atmosphere, so when the bottom elastic film when drop-down, cavity volume expansion, balloon expansion; This moment, the respiratory movement principle of explanation was: diaphram shrinks, and the diaphragm top descends, and the thoracic cavity volume enlarges, and the lung internal gas pressure descends, the lung expansion, and it is air-breathing that show as human body this moment; Otherwise when pushing away on the elastic film of bottom, cavity volume is dwindled, and balloon dwindles.This moment, the respiratory movement principle of explanation was: the diaphram diastole, and diaphragm rises on the top, and the thoracic cavity volume dwindles, and the lung internal gas pressure rises, and lung dwindles, and show as human body and exhale this moment.Because outer cover is transparent, so when the teacher demonstrated, the student can be clear that the phenomenon of demonstration, thereby is readily appreciated that the principle of human body respiration motion, and simple in structure, vivid, has good applied value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, outer cover 1 is transparent, its flexible film 2 in bottom, elastic film 2 surrounds sealed cavity 6 with outer cover 1, and large pipeline 3 is arranged in the cavity 6, and large pipeline 3 upper ends are stretched out outer cover 1 and communicated with atmosphere, large pipeline 3 lower ends are connected with two branch's small pipelines 4, and small pipeline 4 is connected with the elastic film ball 5 of sealing.Described bottom elastic film 2 is a plastic sheeting, pushes on can be flexibly and draws, and elastic film ball 5 is the caulking gum balloon.Large and small pipeline communicates, and balloon communicates with atmosphere by large and small pipeline, and the air pressure in the balloon is consistent with the atmosphere of outside.
