[technical field]
The utility model relates to a kind of teaching aid, is specifically related to a kind of blood circulation teaching aid, belongs to technical field of teaching instruments.
[background technology]
In the prior art, when the teacher explains blood circulation of human body on biology Class, usually explain for blood circulation figure.And because Image Display is static, it can not intuitively show sanguimotor overall process only with the flow direction of arrow indication blood, thereby lacks lively sense, makes the student understand difficulty, affects results of learning.
Therefore, for solving the problems of the technologies described above, the necessary blood circulation teaching aid that a kind of novel structure is provided is to overcome described defective of the prior art.
[utility model content]
For addressing the above problem, the purpose of this utility model is to provide a kind of blood circulation teaching aid of lively, dynamic demonstration blood circulation process directly perceived.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of blood circulation teaching aid, and it comprises demonstration board and is positioned cardiac module, body artery model, the thin vascular pattern of chaeta, vena systemica model, pulmonary artery model, PC model, pulmonary vein model and lever driving device on the demonstration board; Wherein, described cardiac module is divided into atrium sinistrum, atrium dextrum, left ventricle and right ventricle; Described left ventricle, body artery model, the thin vascular pattern of chaeta, vena systemica model and atrium dextrum connect successively; Described right ventricle, pulmonary artery model, PC model, pulmonary vein model and atrium sinistrum connect successively; Described lever driving device is connected on the cardiac module and can drives that cardiac module is beated and the circulating of simulate blood.
Blood circulation teaching aid of the present utility model further is set to: described atrium sinistrum, left ventricle, atrium dextrum, right ventricle are made by having flexible hollow rubber ball, and body artery model, the thin vascular pattern of chaeta, vena systemica model, pulmonary artery model, PC model and pulmonary vein model are made by plastic tube and woven hose.
Blood circulation teaching aid of the present utility model further is set to: be filled with the simulation arterial blood that is mixed by water, red ink, liquid detergent in described atrium sinistrum, left ventricle, body artery model, the pulmonary vein model; Be filled with the simulation venous blood that is mixed by water, blue ink, liquid detergent in described atrium dextrum, right ventricle, vena systemica model and the pulmonary artery model.
Blood circulation teaching aid of the present utility model further is set to: described body artery model, pulmonary vein model, vena systemica model and pulmonary artery model are connected with respectively a syringe that is used for water filling and compensator or trimmer pressure.
Blood circulation teaching aid of the present utility model also is set to: between the atrium dextrum and right ventricle of described cardiac module, between right ventricle and the pulmonary artery model, between atrium sinistrum and the left ventricle, be provided with the one-way valve that rubber is made between left ventricle and the body artery model.
Compared with prior art, the utlity model has following beneficial effect: blood circulation teaching aid of the present utility model is easy to operate, and the process that it can demonstrate blood circulation of human body makes teaching vivid, be conducive to excite student's interest and understandability, thereby improve the quality of teaching.
