Description
Technical field
The utility model relates to education or demonstration equipment, specifically a kind of blood circulation apparatus for demonstrating.
Background technology
The blood circulation system of human body is made up of body circulation and pulmonary circulation two parts.Body circulation starts from left ventricle.Blood is from left ventricle is put out, and some arterial branches of flow through sustainer and derivation thereof, send blood into corresponding organ.Artery is again through branch repeatedly, and caliber is tapered, and number of blood vessel increases gradually, finally arrives capillary, carries out mass exchange herein by intercellular fluid with histocyte.Oxygen and nutriment in blood are absorbed by tissue, and tissue in carbon dioxide and other metabolic products enter in blood, change arterial blood is venous blood.Vein caliber chap gradually around here, number reduces gradually, to the last all veins are all pooled to superior vena cava and inferior caval vein, blood get back to atrium dextrum thus, from atrium dextrum again to right ventricle, thereby completed body cyclic process.Pulmonary circulation is from right ventricle.Venous blood is put out by right ventricle, arrives alveolar capillary network around through pulmonary artery, discharges carbon dioxide at this, absorbs new fresh oxygen, and change venous blood is arterial blood, and then flows back to atrium sinistrum through pulmonary vein.The blood of atrium sinistrum reenters left ventricle, spreads all over whole body again through systemic circulation.Blood is circulated and is constantly turned round with pulmonary circulation by body like this, has completed sanguimotor vital task.
Therefore, blood circulation of human body system is one, and to relate to histoorgan various, and blood is changed complicated process.In current middle and primary schools' science, bioconversion medium and universities' medical speciality or practice, blood circulation of human body is an emphasis, is also a difficult point.
Granted publication number is that the Chinese utility model patent of CN202487053U discloses " a kind of blood circulation of human body demonstration teaching aid ", this teaching aid distributes to simulate the relative position of the each blood circulation organ of human body by the solid of each parts, and by many pilot lamp chains that distribute, are controlled by controller along inditron (representing blood vessel) the successively luminous visual experience of giving media flow in a kind of inditron of people, demonstrate flowing of blood, show the process of dynamic circulation.For the ease of observing, understanding, different inditrons has also been set with the printing opacity cover of different colours outward, for distinguishing different blood vessels: red printing opacity cover can outwards be launched red light, in order to simulate hyperoxic blood or blood vessel; Pink printing opacity cover can outwards be launched pink, in order to simulate high blood or the blood vessel of carbonated after each organ blood exchange.There is following defect in this teaching aid: flash expression blood flow with pilot lamp chain, lack the sense of movement of blood, dynamically sense is not strong; Dynamically indicating structure comprises above-mentioned controller, many pilot lamp chains, multiple button, multiple printing opacity cover, complex structure, parts are various, assembling is very inconvenient, and the very power consumption of this teaching aid, when damaging appears in parts, the replacing of detection, maintenance and the parts of circuit is also wasted time and energy.
