Abstract
The utility model relates to a diaphragm motion simulator. The diaphragm motion simulator comprises a transparent housing and an elastic film arranged at the bottom of the transparent housing, a sealed cavity is formed by the transparent housing and the elastic film, the upper end of an air pipe is communicated with atmosphere outside the transparent housing and the lower end of the air pipe is positioned in the cavity and provided with two branch pipes, and two air bags in the cavity are communicated with atmosphere through the branch pipes respectively. The diaphragm motion simulator utilizes the dynamic process of motion of the elastic film and the size variation of the air bags to straightforwardly and sensitively demonstrate relationship between lungs and diaphragm when people breathe and obtains an excellent teaching effect.
Description
Technical field
The utility model relates to instruments used for education, relates in particular to a kind of diaphram motion simulator that is used for Biology Teaching.
Background technology
Along with the raising that science and technology development and people require teaching, science and technology constantly is introduced in teaching field, to produce the various instruments used for education that are used for aided education, improve teaching efficiency.Various instruments used for education because of with teaching material on knowledge combine closely, can be very directly perceivedly, very perceptual give the student with knowledge-transference, make teaching obtain good effect.Therefore, instruments used for education are more and more paid close attention to.
The human body respiration principle is a very important knowledge point in the biology teaching in junior middle school, at present teacher lecture this knowledge point the time, normally lecture by structoure of the human body figure, figure is static, and the diaphram motion is a dynamic movement process of diaphram and lung interlock, static figure can't demonstrate out this dynamic process intuitively, and the student can not be fine, accept soon, and teaching efficiency is not very desirable.
Summary of the invention
The purpose of this utility model is, a kind of diaphram motion simulator is provided, the mutual relationship of lung and diaphram motion when demonstrating human body respiration directly perceived, perceptually.
To achieve these goals, the technical solution adopted in the utility model is: a kind of diaphram motion simulator, comprise transparent shell and the elastic membrane that is arranged on the transparent shell bottom, transparent shell and elastic membrane constitute the cavity of a sealing, the upper end of tracheae is communicated with atmosphere in the transparent shell outside, the lower end of tracheae is in cavity and have two arms, and two air bags in cavity respectively are communicated with atmosphere by an arm.
In such scheme, transparent shell, elastic membrane and air bag are used for simulating human body, diaphram and lung respectively, the motion of elastic deformation up and down of elastic membrane can cause the size variation of air bag, the motion of the utility model by elastic membrane and the relation of this dynamic process of size variation of air bag lung and diaphram motion when demonstrating human body respiration can obtain good teaching efficiency directly perceived, perceptually.
Description of drawings
Fig. 1 is the structural representation of the utility model diaphram motion simulator;
Fig. 2 is for showing the diaphram motion simulator cut-open view of a duty;
Fig. 3 is for showing the diaphram motion simulator cut-open view of another duty.
Below in conjunction with accompanying drawing the utility model is described in detail.
Embodiment
Referring to Fig. 1 and Fig. 2, diaphram motion simulator of the present utility model comprises transparent shell 1 and is arranged on the elastic membrane 2 of transparent shell 1 bottom, transparent shell 1 and elastic membrane 2 constitute the cavity of a sealing, the upper end of tracheae 4 is communicated with atmosphere in that transparent shell 1 is outside, and the lower end of tracheae 4 is in cavity and have two arms 41.Two air bags 3 are in cavity, and each is connected with an arm 41, is communicated with atmosphere by arm 41.Air bag 3 is by the resilient material manufacturing, when the air pressure in the transparent shell 1 when relative variation takes place in air pressure in the air bag 3, air bag 3 generation elastic deformations, thus its volume also changes.
Two air bags 3 are about tracheae 4 symmetric arrangement, and air bag 3 has human body lobe of the lung shape, and is very vivid, can play the effect of simulated lung better, make students ' understanding deep.Transparent shell 1 is provided with two row's strip projections 12, and projection 12 is arranged in air bag 3 the place aheads, is used for simulating the human body rib, makes whole transparent shell 1 present the human chest image.
Be provided with handle 21 at the middle part of elastic membrane 2, handle 21 is in the outside of transparent shell 1, and being provided with to have made things convenient for of handle 21 spurs elastic membrane 2 up and down.
Diaphram is separated thoracic cavity and abdominal cavity at the bottom in thoracic cavity and the top in abdominal cavity, and the variation of thoracic cavity volume is relevant with the diaphram activity, and when air-breathing, diaphram shrinks, and the diaphram top descends, and the thoracic cavity volume increases, the lung expansion; Just in time opposite during expiration, the diaphram diastole, go up in the diaphram top, and the thoracic cavity volume reduces, the lung expansion.The utility model is simulated human body, diaphram and lung with transparent shell, elastic membrane and air bag respectively.Referring to Fig. 2, when elastic membrane 2 was upwards made elastic movement, the cavity volume in the transparent shell reduced, pressure increases, and the part air in the air bag 3 is forced out in the atmosphere, and air bag 3 volumes reduce, and what simulated this moment is the human body exhalation process; Referring to Fig. 3, pulling handle 21 makes elastic membrane 2 make elastic movement downwards, and the cavity volume in the transparent shell 1 increases, pressure reduces, and air replenishes in the air bag 3 by tracheae 4, and air bag 3 volumes increase, and simulation is the human body breathing process at this moment.The motion of the utility model by elastic membrane and the relation of this dynamic process of size variation of air bag lung and diaphram motion when demonstrating human body respiration can obtain good teaching efficiency directly perceived, perceptually.
