Technical Field

[0001] This utility model belongs to the field of medical teaching equipment technology, and in particular relates to an inflatable model of aortic dissection for teaching purposes. Background Technology

[0002] Aortic dissection, also known as aortic aneurysm, is a serious cardiovascular disease that poses a severe threat to public health. In recent years, thanks to the development and improvement of the National Chest Pain Center over the past decade, the deepening understanding of aortic diseases among medical personnel, and significant advancements in imaging diagnostic technology, cardiovascular surgery, anesthesiology, and extracorporeal circulation techniques, the diagnosis rate of AD has continued to increase, while the surgical mortality rate and complication rate have significantly decreased. Over the past two decades, to improve the treatment outcomes of AD in my country, domestic medical scholars have conducted a large number of fruitful studies, promoting the rapid development of aortic surgery in the country.

[0003] Aortic dissection, a serious cardiovascular disease that has received much attention and research in recent years, currently faces several challenges: First, there is a lack of appropriate teaching models. Teaching methods are too simplistic, relying mainly on textbooks and lectures. This singular teaching approach makes it difficult for students to retain information deeply.

[0004] Although there are some teaching models available, they are not intuitive enough and the teaching is not engaging enough. Utility Model Content

[0005] This utility model discloses an inflatable model of aortic dissection for teaching purposes, which mainly addresses the problem that teaching aortic dissection relies solely on textbooks and teacher lectures, resulting in a monotonous teaching method and a lack of vividness.

[0006] To achieve the aforementioned objective, this utility model provides an inflatable aortic dissection model for teaching purposes, comprising a base, a transparent plate on the base, a simulated intima on one side of the transparent plate, and a first airbag, a second airbag, and a third airbag arranged sequentially and spaced apart from each other on the surface of the simulated intima. The simulated intima, the first airbag, the second airbag, and the third airbag are all semi-sectional structures. An air supply device for independently supplying air to the first airbag, the second airbag, and the third airbag is provided inside the base.

[0007] Preferably, the air supply device includes an inflatable ball, a connecting pipe connected to the inflatable ball, and an inflation pipe connected to the connecting pipe. The inflation pipe includes a first inflation pipe connected to the first airbag, a second inflation pipe connected to the second airbag, and a third inflation pipe connected to the second airbag. Each of the first inflation pipe, the second inflation pipe, and the third inflation pipe is equipped with an air valve.

[0008] Preferably, the simulated inner membrane is provided with a first marking line and a second marking line.

[0009] Preferably, the first airbag, the second airbag, and the third airbag are separated by a diaphragm.

[0010] Preferably, the base is provided with a simulated mezzanine type identifier.

[0011] Preferably, a simulated stent is disposed within the simulated endometrium.

[0012] Preferably, the simulated stent is movable within the simulated endometrium, and both ends of the simulated stent are provided with pull ropes that extend through the simulated endometrium.

[0013] The technical solution provided by this utility model has at least the following technical effects:

[0014] This invention discloses an inflatable aortic dissection model. Through a built-in air supply device in the base, the first, second, and third air bladders can be selectively inflated to simulate various types of aortic dissection. This method makes the teaching process more vivid and helps students form a deeper memory. Furthermore, because the simulated intima and each air bladder are designed with a semi-sectional structure, combined with the use of a transparent plate, students can directly observe the internal structure of the intima, making the teaching activities more vivid and engaging.

[0021] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the embodiments of this utility model, and should not be construed as limiting the utility model.

[0022] like Figure 1 , Figure 2 As shown, this embodiment discloses an inflatable aortic dissection model for teaching purposes, including a base 1. A transparent plate 2 is provided on the base 1. The transparent plate 2 can be made of materials such as glass or plastic. A simulated intima 3 is provided on one side of the transparent plate 2. The simulated intima 3 is made of a rigid material. A first marking line 13 and a second marking line 14 are provided on the simulated intima 3. The first marking line 13 and the second marking line 14 are used to simulate the rupture of the intima 3.

[0023] The simulated inner membrane 3 has a first airbag 4, a second airbag 5, and a third airbag 6 arranged sequentially and spaced apart from each other. The first airbag 4 and the second airbag 5, and the second airbag 5 and the third airbag 6 are separated by a diaphragm 15. All three components of the simulated inner membrane 3 are semi-sectional, allowing observation of their internal structural changes through a transparent plate 2. The base 1 contains an air supply device for independently supplying air to the first airbag 4, the second airbag 5, and the third airbag 6. Figure 1 , Figure 4 The image shows a comparison of the inflated and deflated states of the aortic balloon, simulating the two states of aortic dissection lesion and no lesion.

[0024] Operating principle:

[0025] (1) When the first airbag 4 is inflated separately by the inflation device, the rupture at the position of the first mark line 13 is simulated to rupture, the first airbag 4 expands, and the outer membrane and inner membrane are simulated to separate to form a sandwich, which is used for simulated teaching of Stanford A / DeBakey II type.

[0026] (2) When the second airbag 5 and the third airbag 6 are inflated simultaneously by the inflation device, the rupture at the position of the second mark line 14 is simulated to rupture. The second airbag 5 and the third airbag 6 expand, simulating the separation of the outer membrane and the inner membrane to form a sandwich, which is used for simulation teaching of Stanford B / DeBakey IIIb type.

[0027] (3) When the second airbag 5 is inflated separately by the inflation device, the rupture at the position of the second mark line 14 is simulated to rupture, the second airbag 5 expands, and the outer membrane and inner membrane are simulated to separate to form a sandwich, which is used for simulation teaching of Stanford B / DeBakey IIIa type.

[0028] (4) When the first airbag 4, the second airbag 5 and the third airbag 6 are inflated simultaneously by the inflation device, the rupture at the position of the first mark line 13 is simulated to rupture, the third airbag 6 expands, and the outer membrane and inner membrane are simulated to separate to form a sandwich, which is used for simulated teaching of Stanford A / DeBakey I type.

[0029] By selectively inflating different balloons, various types of aortic dissection are simulated, making the teaching process more vivid and helping students form a deeper memory. Furthermore, because the simulated intima and each balloon are designed with a semi-sectional structure, and with the use of transparent plate 2, students can directly observe the internal structure of the intima, making the teaching activities more engaging and visual.

[0030] like Figure 3 As shown, the air supply device includes an inflatable ball 7, a connecting pipe 8 connected to the inflatable ball 7, and an inflation pipe connected to the connecting pipe 8. The inflation pipe includes a first inflation pipe 9 connected to the first airbag 4, a second inflation pipe 10 connected to the second airbag 5, and a third inflation pipe 11 connected to the second airbag 5. The other ends of the first inflation pipe 9, the second inflation pipe 10, and the third inflation pipe 11 are connected to the corresponding airbags.

[0031] Air valves 12 are equipped on the first inflation tube 9, the second inflation tube 10, and the third inflation tube 11, and a main air valve 12 is provided on the connecting tube 8. The air valves 12 of the first inflation tube 9, the second inflation tube 10, and the third inflation tube 11 are arranged on the surface of the base 1, and the on / off state of each inflation tube is controlled by rotating the air valves 12. In order to facilitate intuitive simulation of the lesion type of aortic dissection, the surface of the base 1 is also provided with simulated dissection type markings 16. The simulated dissection type markings 16 are mainly set next to the air valves 12 of the first inflation tube 9 and the second inflation tube 10, which are marked as Stanford A / DeBakey II type and Stanford B / DeBakey IIIa type, respectively. The control of the air valves 12 corresponding to other types of lesions can be explained in the explanatory label on the surface of the base 1, thereby making the operation more convenient.

[0032] In the treatment of aortic dissection, the use of stents is essential. To accurately simulate the actual situation of stent treatment, a simulated stent 17 is specially designed in this simulation device. This simulated stent 17 is made of a soft material and can move freely within its simulated intima. Both ends of the simulated stent 17 are equipped with pull cords (not shown in the figure) that extend through the simulated intima 3. By manipulating these pull cords, the position of the simulated stent 17 within the simulated intima 3 can be adjusted, thereby simulating the scenario of aortic dissection being treated with stents at different locations. This design makes the simulation teaching process more vivid and intuitive.

[0033] The above-disclosed embodiments are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made on the basis and within the scope of the present utility model should be included within the protection scope of the present utility model.
