Abstract
The utility model discloses a teaching model for demonstrating gas exchange in lungs and tissues. A pulmonary alveolus analog, a lamp belt used for simulating arterial blood flow and a lamp belt used for simulating venous blood flow are arranged on a bottom board; a tracker controlling the lamp belts is arranged on the back face of the bottom board; human body cell tissue patterns are drawn outside the pulmonary alveolus analog on the bottom board; and four transparent arrowheads which represent that a gas enters arterial blood from pulmonary alveolus, enters cell tissues from the pulmonary alveolus, enters the venous blood from the cell tissues and enters the pulmonary alveolus from the venous blood are arranged on the bottom board. The tracker on the back of the bottom board can control the flow speed and the flow direction of lamp beads in the lamp belts, and the calorific value of the lamp belts. The teaching model is simple in structure, low in cost and vivid in demonstration effect and is convenient to process. The whole process, including the conditions of direction change, color change and the like, in the lungs and the tissues, is completely simulated through the teaching model, so that the teaching model particularly contributes to the grasp of students on knowledge points.
Description
Technical field
The utility model relates to a kind of teaching mode, specifically refers to a kind of teaching mode that is used for demonstrating in the lung and organizes gas exchange, belongs to the teaching mode technical field.
Background technology
Gas exchange is a very complicated process in the lung and in the tissue, comprise that oxygen enters the carbon dioxide of discharging blood, the blood and enters in the lung in lung, and the blood change in color of bringing thus, this wherein also relates to the mutual relationship of in-vivo tissue and lung and blood.The biological teacher of school also compares headache when this partial content of explanation, because gas exchange and blood circulation process externally can not observe and experience, change procedure wherein is difficult to again derive and draws, so the student generally feels difficulty when grasping.Model demonstration is to solve pretty good selection of above-mentioned difficulties, and existing demonstrating model is generally relatively exquisiter, though image, true to nature, price is also high, for some country schools, is difficult to especially bear.So teacher's this class model of Design and Machining of doing it yourself is arranged, but simulate effect is undesirable again, is unfavorable for teaching.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provide a kind of simple in structure, cost is low, simulation image be used for demonstrating in the lung and the teaching mode of tissue gas exchange.
The technical solution of the utility model is achieved in that and is used for demonstrating in the lung and the teaching mode of tissue gas exchange, it comprises a base plate, base plate is provided with the alveolar analogies that formed by the bending of strip member, lamp band and the mobile lamp band of simulation venous blood that the simulation arterial blood flows, the lamp band that the simulation arterial blood flows is red, the lamp band that simulation venous blood flows is green, is provided with the tracker of control lamp band at the base plate back side; Be positioned at outer drafting of alveolar analogies on the described base plate human cell tissue pattern is arranged; On base plate, be provided with and represent gas to enter arterial blood, enter cell tissue, enter venous blood, enter IA four transparent arrows from venous blood from cell tissue from arterial blood from alveolar.The tracker of base plate back can be controlled the thermal value of flowing velocity, flow direction and the lamp band of lamp pearl in the lamp band.
Further, described representative gaseous diffusion from alveolar enter arterial blood, two transparent arrows entering cell tissue from arterial blood for green and at arrow other or transparent arrow is marked with " O
2" printed words; Represent gaseous diffusion to enter venous blood and enter IA two transparent arrows and be marked with " CO for redness and on arrow side or arrow from venous blood from cell tissue
2" printed words.
Described alveolar analogies are formed by the bending of ripple water pipe.
Representing gas to enter arterial blood, enter cell tissue, enter venous blood, enter IA four transparent arrow back sides from venous blood luminescent device is arranged from cell tissue from arterial blood from alveolar.
The other arrow that is marked with " arterial blood " printed words and is marked with the expression flow direction of the lamp band that described simulation arterial blood flows, the other arrow that is marked with " venous blood " printed words and is marked with the expression flow direction of the lamp band that simulation venous blood flows.
Represent gaseous diffusion to enter arterial blood and enter the analogies that IA two transparent arrows are positioned at alveolar from venous blood from alveolar.
The utility model is simple in structure, convenient processing, even manual finishing also is very easy to, cost can be finished with interior at 50 yuan, and the demonstration effect is very lively and true to nature, simulated the whole process that reaches gas exchange in the tissue in the lung fully, comprised various situations such as direction, change color, be beneficial to the grasp of student especially this knowledge point.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, from the figure as can be seen, the utility model is used for demonstrating in the lung and the teaching mode of tissue gas exchange, it comprises a base plate 1, base plate 1 is provided with the alveolar analogies 2 that formed by 3 bendings of strip member, lamp band 4 and the mobile lamp band 5 of simulation venous blood that the simulation arterial blood flows, the lamp band 4 that the simulation arterial blood flows is red, and the lamp band 5 that simulation venous blood flows is green; Be provided with the tracker of control lamp band at the base plate back side.Be positioned at outer drafting of alveolar analogies on the described base plate 1 human cell tissue pattern 6 is arranged; On base plate 1, be provided with and represent gas to enter arterial blood, enter cell tissue, enter venous blood, enter IA four transparent arrows 8 from venous blood from cell tissue from arterial blood from alveolar.The tracker of base plate back can be controlled the thermal value of flowing velocity, flow direction and the lamp band of lamp pearl in the lamp band.
Further, described representative gas from alveolar enter arterial blood, from arterial blood enter the transparent arrows 8 of two of cell tissue for green and at arrow other or arrow is marked with " O
2" printed words; Represent gas to enter venous blood and enter IA two transparent arrows 8 and be marked with " CO for redness and on arrow side or arrow from venous blood from cell tissue
2" printed words.
Described alveolar analogies 2 are formed by the bending of ripple water pipe.
Representing gas to enter arterial blood, enter cell tissue, enter venous blood, enter IA four transparent arrow 8 back sides from venous blood and be provided with luminescent device 7 from cell tissue from arterial blood from alveolar, luminescent device 7 is used the lamp band redundance of simulation artery and vein blood flow.
The lamp band 4 other arrows that are marked with " arterial blood " printed words and are marked with the expression flow direction that described simulation arterial blood flows, the lamp band 5 other arrows that are marked with " venous blood " printed words and are marked with the expression flow direction that simulation venous blood flows.
Represent gas to enter arterial blood and enter IA two transparent arrows 8 and be positioned at alveolar analogies 2 from venous blood from alveolar.
This teaching mode demonstration effect is lively, true to nature, has simulated the whole process that reaches gas exchange in the tissue in the lung fully, comprises direction, change color etc., to helping teacher's teaching and student very useful to the grasp of this knowledge point.
