Description

Technical Field

[0001] The utility model relates to a pleural cavity simulation technology, in particular to a pleural cavity simulation device. Background Art

[0002] Open pneumothorax refers to a condition in which the chest wall is damaged, allowing the pleural cavity to communicate with the outside world. When the pleural rupture is large, or there is adhesion or traction between the two layers of pleura, the rupture remains open, and air freely enters and exits the pleural cavity during inspiration and exhalation. The pressure in the pleural cavity changes continuously with breathing, with the pressure in the pleural cavity decreasing during inspiration and increasing during exhalation. Open pneumothorax can cause a series of pathological and physiological changes, resulting in severe respiratory and circulatory dysfunction. At present, the existing simulation models of open pneumothorax are relatively complex in structure, and no good model that can realistically simulate the negative pressure structure of the pleural cavity and the state of pneumothorax has been found.

[0003] How to solve the above problems has become a technical problem that needs to be solved urgently. Utility Model Content

[0004] The utility model aims to provide a pleural cavity simulation device which has a simple structure and can realistically simulate the pleural cavity negative pressure structure and pneumothorax state.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a pleural cavity simulation device, comprising a negative pressure ball; the negative pressure ball comprises a sphere for simulating the human chest cavity and an inflatable balloon for simulating the human lungs, the balloon is placed inside the sphere and a first air vent is provided on the air inlet end of the balloon, one end of the first air vent is connected with the balloon, the other end of the first air vent passes through the sphere, a second air vent is provided at the lower end of the sphere and the second air vent is connected with the sphere, the balloon is connected to the outside atmosphere through the first air vent, the sphere is connected to the outside atmosphere through the second air vent, and switches are provided on the first air vent and the second air vent.

[0007] Furthermore, the switch is a sealing plug.

[0008] Furthermore, the sphere is made of transparent material.

[0009] Due to the adoption of the above structure, the utility model has the following beneficial effects:

[0010] The utility model provides a sphere, a balloon, a first vent and a second vent. The user can extract the air in the sphere through the second vent and then close the second vent, thereby simulating the negative pressure structure of the pleural cavity. The user can also open the first vent and the second vent at the same time, inflate the balloon through an electric air pump and discharge the air in the sphere from the second vent, so that the inside of the sphere is in a negative pressure state, and then close the second vent. At this time, the balloon will not collapse and is connected to the outside atmosphere, thereby simulating the expansion state of lung tissue; finally, the user opens the second vent to connect the sphere to the outside atmosphere, allowing air to enter the inside of the sphere and collapse the balloon, thereby simulating the pneumothorax state; the utility model is not only simple in structure, but also can realistically simulate the negative pressure structure and pneumothorax state of the pleural cavity by connecting the sphere and the balloon to the outside atmosphere.

[0015] Please refer to Figure 1The utility model provides a pleural cavity simulation device, comprising a negative pressure ball; the negative pressure ball comprises a sphere 1 for simulating the human chest cavity and an inflatable balloon 2 for simulating the human lungs, the balloon 2 is placed inside the sphere 1 and a first air vent 3 is provided on the air inlet end of the balloon 2, one end of the first air vent 3 is connected with the balloon 2, and the other end of the first air vent 3 passes through the sphere 1, a second air vent 4 is provided at the lower end of the sphere 1 and the second air vent 4 is connected with the sphere 1, the balloon 2 is connected to the outside atmosphere through the first air vent 3, and the sphere 1 is connected to the outside atmosphere through the second air vent 4, and switches are provided on the first air vent 3 and the second air vent 4. By providing a sphere 1 for simulating a human chest cavity, a balloon 2 for simulating a human bronchus, a first vent 3 and a second vent 4, a user can use an electric air pump to extract the air in the sphere 1 from the second vent 4 and then close the second vent 4, thereby simulating the negative pressure structure of the pleural cavity. The user can also open the first vent 3 and the second vent 4 at the same time, inflate the balloon 2 through the electric air pump and discharge the air in the sphere 1 from the second vent 4, so that the inside of the sphere 1 is in a negative pressure state, and then close the second vent 4. At this time, the balloon 2 will not collapse and communicate with the outside atmosphere, thereby simulating the expansion state of lung tissue; finally, the user opens the second vent 3 to communicate the sphere 1 with the outside atmosphere, allowing air to enter the inside of the sphere 1 and collapse the balloon 2, thereby simulating a pneumothorax state; the utility model is not only simple in structure, but also can realistically simulate the negative pressure structure and pneumothorax state of the pleural cavity by communicating the sphere 1 and the balloon 2 with the outside atmosphere.

[0016] In the present invention, the switch is a sealing plug 5. By providing the sealing plug 5, the switch state of the first vent 3 and the second vent 4 can be controlled to ensure the air tightness of the sphere 1 and the balloon 2.

[0017] In the utility model, the sphere 1 is made of transparent material, which is helpful for the user to observe the deformation process of the balloon 2 in the sphere 1 .

[0018] When the utility model is in use, the sphere 1 and the balloon 2 can be inflated or deflated by an electric air pump. When it is necessary to simulate the negative pressure structure of the human pleural cavity, the user can release the air in the sphere 1 through the second vent 4 and then close the second vent 4; the user can also open the first vent 3 and the second vent 4 at the same time, inflate the balloon 2 through the electric air pump and discharge the air in the sphere 1 from the second vent 4, so that the sphere 1 is in a negative pressure state, and then close the second vent 4. At this time, the balloon 2 will not collapse and communicate with the outside atmosphere, thereby simulating the expansion state of lung tissue; finally, the user opens the second vent 3 to communicate the sphere 1 with the outside atmosphere, allowing air to enter the sphere 1 and collapse the balloon 2, thereby simulating the pneumothorax state.
