Abstract
The utility model relates to a blood circulation simulation demonstrator which belongs to a teaching aid for teaching. The blood circulation simulation demonstrator is composed of a box body, a display board, a heart model, a blood flow line model, a power supply and a conducting wire. When an air bladder is kneaded by hands, the blood in a bottle can perform systemic circulation and pulmonary circulation along a guide pipe in the heart model, and an indicating lamp on the heart model can be in lighting action by circuits. The utility model has a visual effect and can improve the teaching quality.
Description
The utility model relates to a kind of teaching aid, mainly is the blood circulation analog demonstrator that is used to demonstrate human body or animal blood cyclic process.
When biological class is explained blood circulation on the middle school at present, use the wall chart explanation usually, be decorated with heart and sanguimotor blood vessel on the figure.Because what wall chart was showed is static, can not intuitively show sanguimotor process, makes the student understand difficulty, has influenced results of learning.
The purpose of this utility model is exactly to provide a kind of blood circulation analog demonstrator for the deficiency that overcomes existing teaching aid.
The purpose of this utility model can realize by following measure:
This demonstration device comprises casing, display board, heart simulation, blood flow circuit model, power supply, lead, and concrete structure is to be fixed with cardiac module and blood circulation circuit on display board (2).Body circulation pipe (18) one ends are in gas collection blood bottle (20), the other end divides two-way by the sustainer (4) of the left ventricle back of coming out, wherein one tunnel superior vena cava (12) that enters the atrium dextrum through capillary (1) and resistance blood valve (13) enters in the collection blood bottle (19) then, another road enters in the collection blood bottle (19) then through hindering the inferior caval vein (9) that blood valve (7) and capillary (8) enter the atrium dextrum.Pulmonary circulation pipe (26) one ends are in gas collection blood bottle (21), and the other end is divided two-way to converge into one tunnel pulmonary vein (6) that enters the atrium sinistrum more respectively behind PC (14) and duct of Arantius (3) to enter then and collect in the blood bottle (19) by the pulmonary artery (5) of the right ventricle back of coming out.In the atrium sinistrum, left ventricle and atrium dextrum, right ventricle be respectively arranged with pilot lamp (11).
The purpose of this utility model can also realize by following measure:
Gas collection blood bottle (20) (21) is connected with air bag (23) (24) by conduit (22) (25).
Electric battery (16) is connected with pilot lamp with two-way knife switch (17) by lead (15).
Electric battery (16) is connected with pilot lamp with two-way knife switch (17) by lead (15).
Pilot lamp can adopt light emitting diode.
Description of drawings:
Fig. 1 is a casing synoptic diagram of the present utility model.
Fig. 2 is a blood circulation simulation synoptic diagram among Fig. 1, wherein represents heart, pulmonary circulation, body circulation, arrow represent blood flow to.
Fig. 3 shows the heart back side, the annexation of four pilot lamp on expression power supply and the heart.
Fig. 4 is that expression is led to pulmonary circulation pipe, body circulation pipe, air bag, recirculatory pipe and the gas collection blood bottle in display board front, the annexation of collection blood bottle by the cardiac module back side.
The utlity model has following advantage:
1, dynamic teaching, intuitive is strong.
2, simple in structure, convenient operation.
3, be convenient to promote and use.
Below the utility model is described further:
This demonstration device is made into a chest, and a demonstration board is arranged in the chest, and the front of demonstration board is cardiac module and blood circulation schematic model, and blood circulation comprises body circulation and pulmonary circulation two parts.The back side of plate is circuit part, and air bag, Blood bottle, liquid-collecting bottle, body circulation pipe, pulmonary circulation pipe etc.Show that at demonstration board blood carries out the demonstration of body round-robin after the body circulation pipe comes out through the heart model back side and from the left ventricle sustainer, the pulmonary circulation pipe carries out the demonstration of pulmonary circulation through the heart model back side and from the pulmonary artery of the right ventricle back of coming out at demonstration board demonstration blood.
Specific operation process is as follows:
This teaching aid is the circulation of manual pneumatic simulate blood, as long as hold (23) (24) gently and frequently with left hand, blood promptly slowly rises to pipeline by (20) (21), pressing power switch (17) this moment immediately, to swing to A (left ventricle) heart pilot lamp shinny, blood sees through panel and is sent by left ventricle, when blood enters bend place, (27) (28), close (7) at once, continuing the up blood of pressurization walks near (1), should stop pressurization, then blood maintains static, and closes (13) and opens (7) then, blood is come downwards near (8), close (7) again.At this moment religion person can break away from demonstration and teaches, and then opens (7), makes blood slowly by (8), and pressurization blood walks to (9), enters panel and closes (7) or back side resistance blood valve at once.Open (13), make blood slowly walk to (12) by (1) and see through panel, close (13) or back side resistance blood valve immediately, press (17) again and swing to D, the blood that can make the student observe capillary for twice like this passes through.
When carrying out pulmonary circulation, at first press (17) and swing to B, make blood walk to (14) by last method and can stop pressurization, blood is fixed.Said that pressurization makes blood pass through (14) and carries out (6) arrival heart, closed the back side, (13) (7) resistance blood valve immediately, pressed (17) again and swing to C.
Be down at last blood, should at first refund this circulation, left hand is opened (23) (24) valve, and the right hand is opened (7) slowly refunds blood, opens (13) again, and blood is refunded rapidly.With the pulmonary circulation again of this method.
Claims (4)
1, a kind of blood circulation analog demonstrator, belong to teaching aid, it comprises casing, display board, cardiac module, the blood line model, power supply, lead, it is characterized in that on display board (2), being fixed with cardiac module and blood flow recycle circuit, body circulation pipe (18) one ends are in gas collection blood bottle (20), the other end divides two-way by the sustainer (4) of the left ventricle back of coming out, wherein one tunnel superior vena cava (12) that enters the atrium dextrum through capillary (1) and resistance blood valve (13) enters in the collection blood bottle (19) then, another road enters the inferior caval vein (9) of atrium dextrum through resistance blood valve (7) and capillary (8), enter then in the collection blood bottle (19), pulmonary circulation pipe (26) one ends are in gas collection blood bottle (21), the other end divides two-way to converge into one tunnel pulmonary vein (6) that enters the atrium sinistrum more respectively behind PC (14) and duct of Arantius (3) by the pulmonary artery (5) of the right ventricle back of coming out, and enters then to collect in the blood bottle (19); In the atrium sinistrum, left ventricle and atrium dextrum, right ventricle be respectively arranged with pilot lamp (11).
