Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical equipment technology, and in particular relates to a lung model component and a human body model. Background Technology
[0002] A lung model is a medical device that simulates the human respiratory process, allowing trainees to observe and learn.
[0003] An existing lung model includes a lung sac, a main bronchus, and lobar bronchus. The main bronchus is connected to the lobar bronchus and is located outside the lung sac, while the lobar bronchus is located inside the lung sac. When simulating inhalation, air enters the lung sac through the main bronchus and lobar bronchus, causing the lung sac to expand. When simulating exhalation, the gas in the lung sac is expelled through the lobar bronchus and main bronchus, causing the lung sac to contract.
[0004] The bronchial tubes in the aforementioned lung models are individual tubular structures that serve as channels for air to enter the lung sacs. However, in the human body, the real bronchial tubes do not have just one channel, but multiple channels with different diameters, each with a different flow rate. Therefore, the existing lung models do not simulate the human breathing process very well, which affects the observation and learning of trainees. Utility Model Content

One end of the first connecting portion is connected to the main bronchus, and the other end is connected to the first terminal portion. The first terminal portion extends into the left sac. The portion of the first terminal portion extending into the left sac has multiple left respiratory terminals, each of which is tubular and has a different diameter.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0023] like Figures 1 to 3 As shown, an embodiment of this utility model provides a lung model component, including a main bronchus 1, lobar bronchus, left sac 2, and right sac 7. The left sac 2 and the right sac 7 are located on both sides of the main bronchus 1. The main bronchus 1 is connected to the lobar bronchus. The lobar bronchus includes a left lobar bronchus 3 and a right lobar bronchus 8. The left lobar bronchus 3 includes a first connecting portion 4 and a first terminal portion 5. One end of the first connecting portion 4 is connected to the main bronchus 1, and the other end is connected to the first terminal portion 5. The first terminal portion 5 extends into the left sac 2. The portion of the first terminal portion 5 extending into the left sac 2 has multiple left respiratory terminals 6. Each left respiratory terminal 6 is tubular, and the diameter of each left respiratory terminal 6 is different.
[0024] The right lobe bronchus 8 includes a second connecting portion 9 and a second terminal portion 10. One end of the second connecting portion 9 is connected to the main bronchus 1, and the other end is connected to the second terminal portion 10. The second terminal portion 10 extends into the right lung sac 7. The portion of the second terminal portion 10 extending into the right lung sac 7 has multiple right respiratory terminals 11. Each right respiratory terminal 11 is tubular and has a different diameter.
[0025] In one embodiment, the main bronchus 1, the lobar bronchus, the left pulmonary sac 2, and the right pulmonary sac 7 are all transparent. The transparent structure facilitates observation of the specific gas conditions inside the pulmonary sacs.
[0026] In one embodiment, the left lobe bronchus 3 is smoothly connected to the main bronchus 1. Reducing the angle between the left lobe bronchus 3 and the main bronchus 1 improves the smoothness of gas flow.
[0027] In one embodiment, the left lung sac 2 is provided with a first tube 12, the left lobe bronchus 3 is inserted into the first tube 12, and the first connecting part 4 is connected to the first tube 12.
[0028] In one embodiment, the first connecting portion 4 is bonded and fixed to the first connecting tube 12. This improves the connection stability between the first connecting portion 4 and the left lung sac 2.
[0029] In one embodiment, the right lobe bronchus 8 is smoothly connected to the main bronchus 1. Reducing the angle between the right lobe bronchus 8 and the main bronchus 1 improves the smoothness of gas flow.
[0030] In one embodiment, the right lung sac 7 is provided with a second tube 13, the right lobe bronchus 8 is inserted into the second tube 13, and the second connecting part 9 is connected to the second tube 13.
[0031] In one embodiment, the second connecting portion 9 is bonded and fixed to the second connecting tube 13. This improves the connection stability between the second connecting portion 9 and the right lung sac 7.
[0032] The working principle of the lung model component of this utility model embodiment is as follows:
[0033] During simulated human inhalation, air is blown into the main bronchus 1. Air enters the left lobe bronchus 3 and the right lobe bronchus 8 through the main bronchus 1. Air in the left lobe bronchus 3 passes through the left respiratory terminal 6 into the left sac 2, causing it to inflate. Air in the right lobe bronchus 8 passes through the right respiratory terminal 11 into the right sac 7, causing it to inflate. When no air is blown in, air in the left sac 2 is expelled sequentially through the left respiratory terminal 6 and the main bronchus 1, and air in the right sac 7 is expelled sequentially through the right respiratory terminal 11 and the main bronchus 1.
[0034] According to the lung model component of this utility model embodiment, the left respiratory terminal 6 and the right respiratory terminal 11 of different diameters have different flow rates, which can simulate the expansion and contraction of the lung sac caused by gas entering and exiting from different respiratory terminals during human breathing. In addition, the transparent structure allows trainees to observe the specific flow direction of gas in the lung sac from the outside, thus improving the simulation accuracy of the lung model component.
[0035] In other embodiments, the main bronchus 1, the lobar bronchus, the left sac 2, and the right sac 7 may all be opaque structures.
[0036] In addition, one embodiment of this utility model also provides a human body model, including a main body and the aforementioned lung model component. The main body includes a trachea, and the main bronchus 1 of the lung model component is connected to the trachea. The trachea is transparent. This human body model can be used for teaching human intubation. During airway intubation training, the specific position and working status of the catheter can be observed at all times, which is helpful for airway intubation teaching.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
