Abstract
The utility model provides a device for demonstrating the relationship between the lung breathing and the diaphragm movement, and relates to a biological teaching aid. The device is composed of a half-section big mineral water bottle, a Y-shaped pipe, balloons and an elastic film. One end of the Y-shaped pipe is inserted into a rubber plug and exposes the rubber plug. The rest two ends of the Y-shaped pipe are covered with balloons. The Y-shaped pipe is arranged inside the half-section mineral water bottle. The mouth of the half-section mineral water bottle is sealed by the rubber plug, and the bottom is sealed by the elastic film. Compared with the prior art, since the utility model uses the waste big mineral water bottle and other common materials in daily life, the utility model has the obvious advantages of low cost, simple structure, convenient usage, and vivid demonstration. The utility model is a teaching aid and a learning aid which is easy to reform.
Description
Technical field
The utility model relates to a kind of biological teaching aid, relates in particular to and probes into pulmonary respiration and diaphram kinematic relation demonstration device in the bioconversion medium of a kind of junior middle school.
Background technology
In biology teaching in junior middle school, told about the knowledge of lung respiratory movement, but lacked lively, vivid teaching aid, can only influence teaching efficiency with static graphic teaching.
The utility model content
The purpose of this utility model is the deficiency that lacks the teaching aid of probing into lung respiratory movement at existing, and a kind of lively, vivid displaying pulmonary respiration and diaphram kinematic relation demonstration device is provided.
The purpose of this utility model realizes by following technological means: pulmonary respiration and diaphram kinematic relation demonstration device, form by half mineral water bottle, Y tube, balloon and elastic film, Y tube one end inserts rubber plug and exposes, and two ends are with balloon in addition, are placed in the half mineral water bottle.
The oral area rubber stopper seal of described half mineral water bottle, the bottom seals with elastic film.
Compared with prior art the utlity model has following tangible advantage: utilize waste and old big mineral water bottle and the life in common material, with low cost, simple in structure, easy to use, the demonstration vivid, be a kind of teaching aid that is easy to transform and learning aid.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1.Y shape pipe, 2. rubber plug, the 3. big mineral water bottle of half, 4. balloon, 5. elastic film.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail:
The big mineral water bottle 3 of half as shown in Figure 1 has suitable for reading, end opening, and suitable for reading one end of Y tube 1 passes rubber plug 2 with rubber plug 2 sealing, and two ends are in mineral water bottle and be with balloon 4 in addition, and the end opening of the big mineral water bottle 3 of half is with elastic film 5 sealings.
Demonstration time, balloon 4 blown afloat in the big mineral water bottle 3 of half and rubber plug 2 beyond the Great Wall rapidly, demonstration at this moment be getter action; In the big mineral water bottle 3 of half, push away elastic film 5, the smaller volume of balloon 4, what at this moment demonstrate is the expiration effect, remove external force, elastic film 5 recovers original state, and the air pressure in the big mineral water bottle 3 of half reduces, and balloon 4 is heaved again, so repeatedly, pulmonary respiration can be carried out and the diaphram kinematic relation is demonstrated.
In a word, the utility model provides pulmonary respiration and diaphram kinematic relation demonstration device.The above; it only is a part of embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.
