Background technique
Cardiac cycle is both that Physiological Teaching outline requires the key content and Physiological Teaching difficult point grasped.According to
Heart function state will be divided into isovolumic contraction period cardiac cycle, penetrate blood phase, isovolumic relaxation period, filling phase and auricular systole period.Often
Barometric gradient, valve switch, blood flow direction variation are all referred in one period.The knowledge point was not only abstract complicated but also dry as dust,
It is the content that medico over the years generally feels most to find it difficult to learn and is least ready to learn.It is had the following problems during current lecture: the heart
Dynamic periodic process not only be abstracted but also it is complicated, but multimedia courseware be indirectly displaying schematic diagram, and existing teaching mould only show it is quiet
State structure, so student is difficult to imagine its dynamic process；In addition multimedia animation is not directly visible presentation process, will lead to
Raw disturbance of understanding, influences learning effect.

The semilunar valve model (5) for being equipped with semilunar valve control switch (10) thereon is equipped between model (6), for adjusting semilunar valve model
(5) open and close.
The vein model (1), atrium model (2), ventricular model (4), artery model (6) use transparent elastic material,
Atrioventricular valve model (3), semilunar valve model (5) use white, elastic material；
The vein model (1), atrioventricular valve model (3) ventricular model (4), semilunar valve model (5), is moved atrium model (2)
Arteries and veins model (6), atrium regulation handle (7) and ventricle regulation handle (8) are knockdown pieces.
The utility model is made according to a conventional method of the material of market sale.
The advantages of the utility model and beneficial effect are:
1, structure is simple, at low cost, easy to use, and student can Self-operating.
2, barometric gradient, valve switch, blood in cardiac cycle are flowed to intuitiveization by the process of dynamic demonstration cardiac cycle
Student's Understanding memory is convenient in display.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.The cardiac cycle demonstrating model of the present embodiment uses city
The material of field sale makes according to a conventional method.
As shown in Figure 1, the cardiac cycle demonstrating model of the utility model includes: including vein model 1, atrium model 2, room
Room petal type 3, ventricular model 4, semilunar valve model 5, artery model 6, atrium regulation handle 7 and ventricle regulation handle 8；It is connected
Relationship is as follows:
1 upper end closed of vein model, lower end is connect with atrium model 2；
2 upper end of atrium model is connect with vein model 1, and lower end is connect with ventricular model 4, atrium model 2 and ventricle
The atrioventricular valve model 3 that control switch 9 is housed thereon is equipped between model 4；
4 upper end of ventricular model is connect with atrium model 2, and lower end is connect with artery model 6, ventricular model 4 and artery
The semilunar valve model 5 that semilunar valve control switch 10 is housed thereon is equipped between model 6；
6 upper end of artery model is connect with ventricular model 4, lower end closed；
The atrium regulation handle 7, ventricle regulation handle 8 are located at outside atrium model 2 and ventricular model 4, adjust the heart
Dirty contraction and diastole；
Atrioventricular valve control switch 9 adjusts the open and close of atrioventricular valve model 3 respectively, and semilunar valve control switch 10 adjusts half
The open and close of month petal type 5；
The vein model 1, atrium model 2, atrioventricular valve model 3, ventricular model 4, semilunar valve model 5, artery model 6 are adopted
With transparent elastic material, atrioventricular valve model 3, semilunar valve model 5 use white, elastic material；

Hand 8 is knockdown pieces.
The utility model use process:
With conventional method according to, by after the assembly of cardiac cycle demonstrating model, addition red liquid simulates blood shown in Fig. 1
Liquid closes atrioventricular valve control switch 9 and semilunar valve control switch 10.It presses ventricle regulation handle 8 and simulates ventricular contraction, intraventricular pressure
It increases, semilunar valve control switch 10 is closed, and the isovolumic contraction period of cardiac cycle is simulated.Open semilunar valve control switch 10, blood
Artery model 6 is injected by ventricular model 4, that simulates cardiac cycle penetrates the blood phase.
Semilunar valve control switch 10 is closed, ventricle regulation handle 8 is stretched out and the simulation ventricle of atrium regulation handle 7 relaxes
, indoor drops, atrioventricular valve control switch 9 is closed, and the isovolumic relaxation period of cardiac cycle is simulated.Open atrioventricular valve control switch
9, blood passes back into ventricular model 4 through atrium model 2 from vein model 1, simulates cardiac cycle ventricular filling period.
It presses atrium regulation handle 7 and simulates atrial contraction, intra-atrial pressure increases, and atrioventricular valve control switch 9 is opened, and blood continues
Ventricular model 4 is passed back into from vein model 1 through atrium model 2, simulates the auricular systole period of cardiac cycle.One is completed at this time
The presentation process of cardiac cycle.
Practical application shows that the model is not only simple in structure, at low cost and very easy to use.
