Description

Technical Field

[0001] The invention relates to the technical field of respiratory exercise demonstration teaching aids, in particular to a respiratory exercise demonstration teaching aid. Background Art

[0002] Flail Chest is a serious chest injury that usually occurs when multiple rib fractures occur, resulting in the formation of a soft chest area and paradoxical respiratory movements. This pathological mechanism causes the soft chest area to collapse during inspiration and bulge during exhalation, interfering with normal breathing and possibly causing acute respiratory failure. Due to the complexity and danger of paradoxical respiratory movements, a model that can accurately demonstrate this phenomenon is urgently needed in medical teaching and clinical training to help students and medical staff understand its pathogenesis, symptoms, first aid measures, and nursing priorities.

[0003] However, the existing processing equipment has the following shortcomings:

[0004] In medical education, teaching models are of great significance, helping students to intuitively understand the structure and physiological mechanisms of the human body. However, existing chest anatomy teaching models have prominent problems. Most of them only statically display the basic structures of the chest bones and muscles, which exposes their shortcomings when encountering rib fractures and abnormal respiratory movements. Rib fractures are common in clinical practice, and abnormal respiratory movements are related to the patient's breathing, circulation, and even life. If medical staff do not fully understand them, they are prone to misdiagnosis and mistreatment. There is an urgent need to design a new model, which must not only accurately present the normal respiratory movement of the human body and show the coordinated changes of the thorax and respiratory muscles, but also simulate the abnormal respiratory movement after rib fractures, to help improve the teaching and training effect and cultivate professional talents.

[0040] according to Figure 6-Figure 7 As shown, the main air pipe 27 is connected with the interior of the branch air pipe 26, and the main air pipe 27 is connected with the interior of the air bag 28. Under the pressure of the user, gas can be pumped into the main air pipe 27 through the air bag 28, so that the main air pipe 27 forms a breathing effect. When the air bag 28 is released, the gas flows out from the lung model in the opposite direction due to elastic potential energy and pressure difference, simulating the exhalation action. This cycle is repeated, realistically showing the complete breathing cycle of the human body.

[0041] according to Figure 1-Figure 3 As shown, there are four universal wheels 3, which are arranged in a circular array with the vertical center line of the support column 2 as the axis. The structure of the simulated rib 8 can be supported by the support column 2 to ensure the stability of the simulated rib 8 in the simulated state.

[0042] The effect achieved by the whole mechanism is as follows: the diaphragm 1 23 in the connecting sleeve 1 20 on the affected side is straight, the diaphragm 24 in the connecting sleeve 2 22 on the healthy side is convex to the airway 26 side and has a certain initial tension, the diaphragms are connected by a drawstring 25, and the other side is connected to the lung structure on the same side, and the diaphragm 1 23 is connected to the chamber of the softening zone; when simulating inhalation, the airbag 28 is pressed, and the airbag 28 injects gas into the airway 26 through the main airway 27, and the gas enters the connecting sleeve 1 through the airway 26. 20 and connecting sleeve 22. The gas in connecting sleeve 1 20 flows to the right side under the cover of diaphragm 1 23 and enters connecting sleeve 22. Connecting sleeve 22 injects gas into the right lung 18 to increase the air pressure in the lung model on this side. When the gas enters connecting sleeve 22, the gas pushes the protruding diaphragm 24. Diaphragm 24 gradually recovers to be straight under the pressure of the gas. When diaphragm 24 recovers to be straight, it pulls the pull rope 25. The pull rope 25 pulls diaphragm 1 23. Diaphragm 1 23 gradually bulges. The softened part 17 is pulled in cooperation with the pull rope 25, so that the softened part 17 is sunken into the left lung 16; at the same time, due to the elastic effect of the diaphragm 1 23 and the diaphragm 2 24, the gas is more likely to move to one side, so that the gas is exchanged between the two lungs, that is, abnormal breathing movement; exhalation process: after the end of inhalation, the diaphragm 1 23 and the diaphragm 2 24 are in a state of storing a certain elastic potential energy, so that the straight diaphragm 2 24 after inhalation is more inclined to restore the convexity; and the convex diaphragm 1 23 after inhalation is more inclined to restore the flat The diaphragm 1 23, the diaphragm 24, the pull rope 25, the left lung 16, the softening part 17 and the right lung 18 are arranged to display the relevant anatomical structure of the chest, and by simulating the inhalation and exhalation process of the normal lung, the formation of the softening area of ​​the chest after multiple rib fractures and its abnormal breathing movement can also be displayed.
