[0002] In recent years, people's understanding of the role of multiple risk factors for cardiovascular disease and the protection of target organs such as the heart, brain, and kidneys has continued to deepen, and the diagnostic criteria for hypertension have also been constantly adjusted. It is currently believed that patients with the same blood pressure level have different risks of developing cardiovascular disease. Therefore, the concept of blood pressure stratification has been developed, that is, patients with different risks of cardiovascular disease should have different appropriate blood pressure levels.

[0003] For example, a teaching model of hypertension caused by renal artery obstruction with publication number CN213458658U includes a base, a liquid circulation device, a switch, a heart model, a kidney model, a support frame, a ligation device and a measuring device, wherein the liquid circulation device is arranged in the base; the liquid circulation device is connected to the heart model and the kidney model respectively; the switch controls the operation of the liquid circulation device; the switch is arranged in the base; the heart model and the kidney model are connected; the heart model and the kidney model are fixed to the base through the support frame; the ligation device is arranged on the kidney model; and the measuring device is arranged on the heart model. The utility model is used to identify the connection between the heart and the kidney and the hypertension caused by pathological changes, and is combined with the clinical typical blood pressure value and the risk factor assessment performance, so that learners can understand and remember more easily, and improve the teaching efficiency and quality.

[0027] The support assembly 3 includes a plurality of connecting blocks 31 fixedly installed near the bottom of the model main body 1 near the four sides, and the opposite sides of two adjacent connecting blocks 31 are connected with a rotating shaft 32 for common rotation near the bottom, and the outer periphery of the rotating shaft 32 is fixedly sleeved with a rectangular plate 33 near the front and rear ends, and the front and rear sides of the rectangular plate 33 are provided with a plurality of through holes A near the bottom, and the plurality of through holes A are linearly arranged from top to bottom, and the inner cavity of the rectangular plate 33 is movably connected with a supporting column 34, and the front and rear sides of the supporting column 34 are provided with a through hole B near the top, and the through hole B is connected with the adjacent through hole A, and the bottom of the supporting column 34 is fixedly installed with a supporting block 35, and the height of the model main body 1 can be adjusted and the height of the model main body 1 can be changed by setting the supporting column 34, the supporting block 35 and the rectangular plate 33, so as to facilitate students who are far away from the podium to watch the teaching process.

[0028] A rectangular block 341 is fixedly installed near the top of the inner cavity of the support column 34, and telescopic columns 342 are fixedly installed near the middle position on both sides of the rectangular block 341. Limiting columns 343 are fixedly installed at the ends of the telescopic columns 342, and the ends of the limiting columns 343 are movable through the inner cavities of the adjacent through holes B and the adjacent through holes A respectively. By setting the limiting columns 343 and the spring A3421, the rectangular blocks 341 and the cooperation between the through holes A and B, the height of the model main body 1 can be adjusted again to improve the teaching effect.

[0029] The outer circumference of the telescopic column 342 is movably sleeved with a spring A3421, and the two ends of the spring A3421 are respectively fixedly connected to the adjacent rectangular block 341 and the adjacent limiting column 343. By setting the spring A3421, the limiting column 343 can stably penetrate the inner cavity of the through hole A and the through hole B.

[0030] Embodiment 2: This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 - Figure 3 and Figure 5 The limiting component 4 includes a rotating block 41 fixedly sleeved on the outer periphery of the rotating shaft 32 and a trapezoidal block 42 movably inserted on one side of the rotating block 41. The trapezoidal block 42 is square, and a connecting rod 43 is fixedly installed on one side of the trapezoidal block 42 near the front and rear sides. The ends of the connecting rod 43 movably penetrate one side of the support plate 2 and are jointly fixed with a handle 44. By setting the rotating block 41, the trapezoidal block 42, the connecting rod 43 and the handle 44, the support column 34 and the support block 35 can be folded and stored, which is convenient for the staff to carry the model body 1 and improves the use effect of the device.

[0031] The top and one side of the rotating block 41 are provided with a card slot 411, and the trapezoidal card block 42 is movably inserted in the inner cavity of the card slot 411. The card slot 411 is adapted to the trapezoidal card block 42, and when the rectangular plate 33 is perpendicular to the ground, the trapezoidal card block 42 is inserted in the inner cavity of the adjacent card slot 411, which can improve the effect of limiting the rotating block 41.

By setting the spring B431, the trapezoidal block 42 cannot be detached from the slot 411.

[0033] Working principle: When the utility model is in use, when the teaching staff needs to teach, taking the limiting component 4 on one side as an example, by pulling the handle 44 and connecting it through the connecting rod 43 fixed on the handle 44, the trapezoidal block 42 is moved to one side away from the inner cavity of the adjacent slot 411, and then the staff can flip it to ninety degrees through the support column 34, and release the handle 44. Under the action of two springs B431, the trapezoidal block 42 is inserted into the inner cavity of the adjacent slot 411, so that the support column 34 can be limited; when use is completed, the trapezoidal block 42 is inserted into the inner cavity of the adjacent slot 411, and the rectangular plate 33 can be stored, which is convenient for the staff to carry, and by setting The connecting block 31, the rotating shaft 32, the rectangular plate 33, the supporting column 34 and the supporting block 35 can support the model main body 1 to change the height of the model main body 1, so that students who are far away from the podium can watch the teaching process. When the height of the model main body 1 needs to be adjusted, the limiting column 343 and the spring A3421 are squeezed to the opposite side, and the supporting block 35 is pulled downward. Under the elastic force of the two springs A3421, the ends of the two limiting columns 343 pass through the inner cavity of the adjacent through hole B, which is convenient for adjusting the length of the supporting column 34. The adjustment method of the remaining supporting columns 34 is as described above and will not be repeated here. The height of the model main body 1 can be adjusted again to improve the teaching effect.
