Description
Technical field
The utility model belongs to medical teaching equipment, particularly demonstrates the teaching aid of pulmonary artery air embolism and heart blood circulation.
Background technology
In traditional air embolism experimental teaching, be all to adopt rabbit to make sample, that is: in the auricular vein of rabbit, inject air, treat that it after death cuts thoracic cavity open, take out heart and be placed in the vessel that water is housed, then cut the visible gas of heart open and emit, with this, illustrate that the cause of the death of rabbit is that air embolism causes.This experiment can not be seen the process of air embolus operation and the cardinal principle of air embolism, operates more difficult and needs certain skill, and the economy expenditure of experimental teaching is also larger.Students in Teaching also is difficult to understand the principle of heart blood circulation in addition.
Summary of the invention
The purpose of this utility model is to provide a kind of simulated lung artery air embolism demonstrating model, and it is simple in structure, easy to operate, teaching is visual and understandable, it is economical to use, and can carry out the demonstration of heart blood circulation.
The technical scheme that the solution the purpose of this utility model is taked is: according to the human body real structure, the left ventricle of simulation, atrium sinistrum, right ventricle, atrium dextrum, left lung, right lung, tricuspid valve, clapper, vein and artery are connected into to model, pulmonary artery tube end dress clapper also accesses in right ventricle, atrium dextrum is connected respectively a liquid-accumulating trough that seals with left ventricle with sustainer through superior and inferior vena cava, atrium dextrum also connects power pump by pipe, pulmonary vein access atrium sinistrum.
On described right ventricle, also connect a power pump, a clapper has been housed in superior and inferior vena cava, on the wall of left ventricle and atrium sinistrum, be provided with transparent observation panel.
On the vein arm of left lung and right lung, be provided with the simulation alveolar.
demonstration principle of work: when the heart this demonstrating model and all blood vessels are full of red liquid, (4～5ml) (annotate: power pump 1 interlinks with atrium dextrum power pump suction certain quantity of fluid, be equivalent to the atrium dextrum diastole) this moment red liquid from liquid-accumulating trough (be equivalent to body blood circulation exchange), by superior and inferior vena cava, flow into atrium dextrum, when compression power pump I when (being equivalent to the contraction of atrium dextrum), tricuspid valve is opened, clapper in superior and inferior vena cava is closed, liquid enters right ventricle by atrium dextrum under power pump II swabbing action simultaneously, clapper by right ventricle on pulmonary artery flows into pulmonary artery and branch, after alveolar inflow pulmonary vein enters atrium sinistrum, liquid flows into left ventricle (can see that by atrium sinistrum and left ventricle observation panel the liquid that 4～5ml is arranged flows out) by atrium sinistrum, final liquid flows into liquid-accumulating trough (being equivalent to the exchange of body blood circulation) from left ventricle, this cyclic process can go round and begin again under the effect of power pump carrying out.if in this normal cyclic process, in the hand back vein of the simulation that is connected with superior and inferior vena cava, inject 10～20ml air, visible air enters atrium dextrum with blood through superior and inferior vena cava, and be stirred into red foam-like liquid, this liquid enters right ventricle and pulmonary artery through atrioventricular valve (tricuspid valve) under the effect of power pump, pulmonary artery branch, when a large amount of air enters atrium dextrum, visible these foamed liquid are compressed and expansion in atrium dextrum, serious obstruction the operation of liquid, we can also see in the process of observing, with air capacity, enter the increase of atrium dextrum, the amount of liquid that is flowed out by the atrium sinistrum observation panel reduces thereupon, and contain a certain amount of bubble.At the pulmonary artery branch place, be also shown in the obstruction of air embolus, cause the cutout of pulmonary artery branch.This analog demenstration process, can demonstrate the overall process that air embolus moves, vivid, the straightaway lethal basic reason of embolism---the blood circulation disorder that paraphrased intuitively.
useful technique effect of the present utility model is: this device has been simulated the principle of human heart structure and pulmonary circulation and has been made, in presentation process, illustrate due to atmospheric density lower than fluid density, so when air enters the right heart, contraction due to heart, air is compressed, thereby alleviated the impulsive force to atrioventricular valve, the amount of liquid inflow this moment right ventricle obviously reduces, when a large amount of gas enters just visible air compressed and expansion in atrium dextrum of atrium dextrum, make heart be in an ineffective contraction, diastole state, this phenomenon animal experiment can not be observed, so, this apparatus structure is simple, easy to operate, impart knowledge to students visual and understandable, have certain science and extraordinary object teaching practicality.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.

Embodiment
referring to Fig. 1, this demonstrating model adopts transparent material to make according to the human body real structure, atrium sinistrum 11 by simulation, left ventricle 12, atrium dextrum 8, right ventricle 9, , right lung 1, left lung 2, tricuspid valve 10, clapper, vein and artery connect into model, the tube end dress clapper 15 of pulmonary artery 6, and pulmonary artery 6 access right ventricle interior 9, atrium dextrum 8 is connected respectively a liquid-accumulating trough 19 that seals with left ventricle 12 with sustainer 18 through superior and inferior vena cava 14, the red blood of packing in liquid-accumulating trough 19 and simulating, atrium dextrum 8 also connects this power pump I 16 by pipe, pulmonary vein 7 is connecting atrium sinistrum 11.On described right ventricle 9, also connected an other power pump II 17, during this power pump work, be in suction state, made to demonstrate effect better.One clapper 13 is housed in superior and inferior vena cava 14, prevents that simulate blood from directly entering in liquid-accumulating trough 19.On the wall of left ventricle 12 and atrium sinistrum 11, also be provided with transparent observation panel, facilitate observation of students blood mobility status therein and the formational situation of foam-like liquid.On the vein arm of left lung 2 and right lung 1, be provided with simulation alveolar 3, thereby make this demonstrating model more true to nature.
