[0034] First embodiment:

[0035] In conjunction with Figures 1-5 The present application discloses a great artery elastic reservoir simulation device, comprising:

[0036] The great artery elastic reservoir simulation device of the present application comprises a simulated left ventricle unit, an auxiliary component and a simulated aorta unit.

[0037] The simulated left ventricle unit 1 is composed of a balloon capable of absorbing water and compressing water, and the right end of the balloon is connected with a water inlet 9 for connecting a water source to realize the filling of the balloon. The balloon is connected with the auxiliary component 2 through a pipeline, and when the balloon is compressed, water can be ejected to simulate the left ventricle ejection process.

[0038] Second embodiment:

[0039] The auxiliary component 2 is internally composed of an adjusting pipe 201, and the core structure thereof comprises rotating blocks 202, movable rods 203, second movable rods 204, adjusting plates 205 and adjusting blocks 206. The rotating blocks 202 are provided in two groups and are connected to the upper and lower ends inside the adjusting pipe 201 to provide support points for the movement of the movable rods and the adjusting plates; the first movable rod 203 and the second movable rod 204 are respectively arranged in the middle of the two groups of rotating blocks 202 and are hingedly connected with each other to form a movable connecting structure; the adjusting plates 205 are provided in two groups and are respectively connected to the outer sides of the first movable rod 203 and the second movable rod 204, and when the first movable rod 203 and the second movable rod 204 are rotated relative to each other, the two groups of adjusting plates 205 can be rotated and adjusted inside the adjusting pipe 201 to change the flow area of the adjusting pipe 201 and realize the adjustment of the water flow. The adjusting block 206 is arranged at the upper end of the adjusting pipe 201, the lower end of the adjusting block 206 penetrates through the adjusting pipe 201 and is connected to the upper end of the first movable rod 203, and by operating the adjusting block 206, the rotation of the first movable rod 203 and the second movable rod 204 can be conveniently controlled, and the flow is further adjusted.

[0040] Third embodiment:

[0041] The simulation aortic unit 3 is a main pipeline, one end of the main pipeline is connected with the right side of the adjusting pipe 201 of the auxiliary component 2, for receiving water simulated left ventricular ejection and water after flow adjustment, and the main pipeline receives left ventricular ejection. The output end of the right side of the main pipeline is fixedly connected with a branch assembly 4, the branch assembly 4 includes a hard pipe 5 and an elastic hose 6, which are fixedly connected at the front and rear ends of the branch assembly 4. The elastic hose 6 is made of transparent latex or silicone, has good elasticity and retractability, and the transparent property can clearly show the flow state of the water flow in the pipe and the expansion and contraction deformation process of the lumen in the ejection process, for directly simulating the elastic large artery blood vessel; the hard pipe 5 is made of PVC or glass, which is a hard material without elasticity, and is used as a contrast pipeline. The elastic hose 6 is provided with an elastic body 7 in the middle, which is composed of natural rubber material and cooperates with the elastic hose 6 to realize large amplitude elastic deformation and rapid rebound, and more accurately simulate the elastic properties of the large artery blood vessel. Due to the transparent design of the elastic hose 6, students can clearly observe the deformation of the elastic body 7 under the impact of the water flow, and the dynamic process of the elastic body 7 driving the hose to retract to push the water flow to continue to flow. The output ports of the right ends of the hard pipe 5 and the elastic hose 6 are fixedly connected with water outlets 8 for discharging water flow, which is convenient for observing and comparing the liquid flow.

[0043] Preparation stage: select a suitable specification of water-absorbing and compressed water-jetting balloon as the simulation left ventricular unit 1, determine the balloon capacity according to the actual demonstration requirements, and connect the water inlet 9; select the adjusting pipe 201, rotating block 202, movable rod 203, second movable rod 204, adjusting plate 205 and adjusting block 206 of suitable material and specification, and assemble the auxiliary component 2; use a latex or silicone hose with good elasticity as the elastic hose 6, and install an elastic body 7 composed of natural rubber material in it, select a PVC or glass pipe as the hard pipe 5, and connect the simulation aortic unit 3, the branch assembly 4, the hard pipe 5 and the elastic hose 6. Connect and install all components according to the structural relationship, ensure that the connection is tight and there is no water leakage. Place a collection container at the end of the hard pipe 5 and the elastic hose 6 for collecting the water flowing out, which is convenient for observation and comparison.

[0044] Demonstration stage: connect the water source with the water inlet 9 of the simulated left ventricular unit 1, inject water into the balloon, and close the water source when the water in the balloon reaches an appropriate amount. Adjust the position of the adjusting plate 205 by operating the adjusting block 206 of the auxiliary component 2, and set the simulated left ventricular ejection flow. Then compress the balloon by hand, observe the water ejected from the balloon, and after the flow regulation of the auxiliary component 2, the water enters the main pipeline of the simulated aortic unit 3, and then shunts into the elastic hose 6 and the rigid hard pipe 5. At this time, the elastic hose 6 and the rigid hard pipe 5 have liquid flowing in them. After stopping compressing the balloon, the elastic hose 6 can be obviously retracted under the action of the elastic body 7, the internal liquid continues to flow forward into the collection container, and the liquid in the rigid hard pipe 5 stops flowing. By comparing the amount of liquid in the collection container and the duration of flow, as well as the different demonstration effects after adjusting the flow, students can directly observe the role of the aortic elastic reservoir in the heart ejection process and the physiological changes under different flows. During the teaching process, teachers can combine the demonstration process to explain the physiological mechanism of the systolic and diastolic periods of the heart, the importance of aortic elasticity in maintaining continuous blood flow, and the principle of heart ejection flow regulation.

[0045] Therefore, in summary, the aortic elastic reservoir simulation device of the present application can simulate left ventricular ejection, adjust ejection flow, and demonstrate the process of aortic elastic retraction. At the same time, the liquid flow conditions of elastic and inelastic pipelines are compared to help students intuitively understand the role of the aortic elastic reservoir in the heart ejection process and the change mechanism under different physiological conditions.

[0046] In summary, the above only describes preferred embodiments of the technical scheme of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
