Description

Technical Field

[0001] The utility model relates to the technical field of medical teaching aids, in particular to a tracheal intubation teaching aid. Background Art

[0002] Tracheal intubation refers to the insertion of a tracheal tube into the patient's trachea through the mouth or nose to assist the patient's breathing, relieve tracheal obstruction, and absorb tracheal secretions. Tracheal intubation is mainly used to assist the patient's breathing, relieve tracheal obstruction, and absorb tracheal secretions. When the patient needs to undergo general anesthesia surgery, or suddenly stops breathing and cannot breathe independently, or the trachea is compressed, there are too many tracheal secretions that cannot be cleared by themselves, resulting in tracheal obstruction, symptoms such as difficulty breathing, shortness of breath, cyanosis of the lips, dizziness and fatigue will occur, and timely tracheal intubation is required to assist breathing and improve hypoxia.

[0003] In clinical practice, before actually performing tracheal intubation, medical staff need to practice multiple times using tracheal intubation teaching aids to increase their practical proficiency in tracheal intubation. However, the existing intubation teaching aids in hospitals are designed with an integrated colored structure. The structures of the human trachea and epiglottis simulated inside the teaching aid model are blocked from external vision. During practice, medical staff can only control the intubation by constantly groping to lift the epiglottis and then insert the intubation tube into the trachea. During this operation, the medical staff's responsible instructor cannot observe and correct the medical staff's practice techniques through the teaching aid model.

[0004] For example, a tracheal intubation model with publication number CN213635025U includes a human body model body, a sensor component, and a prompt device electrically connected to the sensor component; the human body model body includes an openable and closable simulated mouth, a simulated mandible that controls the opening and closing of the simulated mouth, and a trachea connected to the simulated mouth; the sensor component is arranged in the simulated mouth. The tracheal intubation model of the present invention enables trainees to better identify problems in their own operation during the training process and obtain objective and clear feedback, so that trainees can understand the precautions and key points of tracheal intubation. At the same time, the mouth area of ​​the tracheal intubation model of the present invention can be adjusted according to actual operation to make the mouth opening angle larger, thereby approaching the condition of real clinical patients and better simulating the actual clinical conditions of clinical patients. During intubation practice, the human body model designed in this patent application cannot be used by medical staff and instructors to observe the displacement state of the front end of the cannula in real time. Therefore, during the practice, medical staff can only lift the front end of the cannula by groping and inserting it into the trachea. During the practice, if the medical staff makes incorrect manipulation movements, the instructor cannot intervene in time. This will result in the instructor not providing timely and real-time guidance to the medical staff on the manipulation during practice, resulting in the medical staff being unable to quickly master the correct manipulation of tracheal intubation, making the entire practice process inefficient.

DETAILED DESCRIPTION

[0023] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with specific embodiments of the present invention and the corresponding drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0024] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] The embodiment of the utility model provides a tracheal intubation teaching aid, comprising a teaching aid model body 1;

[0026] Refer to the attached Figures 1 to 3As shown, the appearance of the teaching aid model body 1 is similar to the appearance and structure of the human head. The teaching aid model body 1 is provided with an air inlet groove 11 similar to the structure of the human mouth. A cavity 12 is provided below the air inlet groove 11. The cavity 12 is similar to the structure of the human oral cavity. An intubation teaching aid 2 similar to the structure of the trachea in the human oral cavity is provided in the cavity 12 of the teaching aid model body 1. A base 3 is provided below the teaching aid model body 1.

[0027] Refer to the attached Figure 3 and 4 As shown, the intubation teaching aid 2 includes an oral support portion 21, a groove 22 is provided on the oral support portion 21, a tongue portion 23 similar to the structure of the human tongue is fixedly provided in the groove 22, an esophageal portion 24 similar to the structure of the human esophagus is extended from the rear side of the oral support portion 21, and a tracheal portion 25 is fixedly provided below the oral support portion 21 and between the tongue portion 23 and the esophageal portion 24. The interior of the tracheal portion 25 is provided with through holes 26 running through both ends, so that The tracheal portion 25 has a similar structure to the human trachea. The top of the tracheal portion 25 extends into the groove 22 of the oral support portion 21, so that the through hole 26 of the tracheal portion 25 is connected to the groove 22. An arc-shaped shielding member 27 is provided at the top edge of the tracheal portion 25 near the tongue portion 23. The arc-shaped shielding member 27 is made of flexible silicone. In its natural state, the arc-shaped shielding member 27 is collapsed and can just cover the top edge of the tracheal portion 25.

[0028] When in use, the front end of the tracheal tube can be placed into the cavity 12 area through the air inlet groove 11 on the teaching model body 1. Among them, the arc-shaped shielding member 27 made of flexible silicone material in the collapsed state is similar to the structure of the human epiglottis. The epiglottis is in a normal state of shielding the trachea to prevent foreign matter from entering the trachea. Therefore, during the actual operation of tracheal intubation, medical staff need to control the tracheal tube to lift the epiglottis before inserting the tracheal tube into the patient's trachea.

[0029] To this end, during practice, the tracheal tube needs to be controlled so that the front end of the tracheal tube lifts up the collapsed arc-shaped shielding piece 27, exposing the through hole 26 at the top of the tracheal portion 25, and the front end of the tracheal tube is inserted into the through hole 26 of the tracheal portion 25 and extends a certain distance to complete the insertion operation of the tracheal tube and the tracheal portion 25. Among them, the tongue portion 23 will play a certain obstructive role during the practice of tracheal intubation, thereby simulating the human tongue in the actual operation process. When the patient is in a coma, the tongue naturally falls back and causes obstruction to the insertion of the tracheal tube. Therefore, the utility model can be closer to the actual operation environment of tracheal intubation when used.

[0030] In a further preferred embodiment, referring to the attached Figure 5As shown, after the middle part of the teaching aid model body 1 is cut, the teaching aid model body 1 forms a symmetrical first teaching aid model 13 and a second teaching aid model 14, and the oral support part 21, the esophageal part 24 and the tracheal part 25 are all fixedly connected to the first teaching aid model 13, wherein the first teaching aid model 13 is a colored setting, that is, the first teaching aid model 13 is a non-transparent setting, and the second teaching aid model 14 is a fully transparent setting;

[0031] When using the utility model, the utility model can be practiced in various ways according to the medical staff's proficiency in tracheal intubation.

[0032] First, for medical staff who have not mastered the tracheal intubation technique; the second teaching aid model 14 is disassembled from the first teaching aid model 13, leaving only the first teaching aid model 13 for medical staff to practice. During the practice, the medical staff will face the cut inner side of the first teaching aid model 13 toward themselves, and then place the front end of the tracheal tube into the chamber 12 along the air inlet groove 11, and then use the front end of the tracheal tube to lift the collapsed arc-shaped shielding piece 27. During this operation, if the medical staff cannot lift the collapsed arc-shaped shielding piece 27, the instructor can manually intervene in the front end of the tracheal tube directly from the side, so that the tracheal tube is fine-tuned to smoothly lift the collapsed arc-shaped shielding piece 27, and the practicing medical staff can observe the instructor's assistance process through the inner side exposed by the cut of the first teaching aid model 13, so as to obtain correct guidance and teaching of tracheal intubation.

[0033] At the same time, during the practice, since the cut inner side of the first teaching model 13 is in an unobstructed state, medical staff can observe the displacement state of the front end of the tracheal tube in real time, and with the assistance of the instructor, repeatedly practice lifting the collapsed arc-shaped shielding member 27. Therefore, this practice method is suitable for medical staff who have not mastered the tracheal intubation technique.

[0034] Secondly, for medical staff who have initially mastered the tracheal intubation technique; only the first teaching aid model 13 is retained for medical staff to practice, and the cut inner side of the first teaching aid model 13 is turned away from the body, so that the colored and non-transparent first teaching aid model 13 causes a visual obstruction to the intubation teaching aid 2. During practice, medical staff need to rely on their own techniques to practice the tracheal intubation technique in a blind state. Since the medical staff's vision is obstructed, the instructor can guide the medical staff to operate verbally, so that the medical staff can smoothly control the tracheal intubation to collapse. The arc-shaped shielding member 27 in the sunken state is lifted up until the tracheal tube can be inserted into the through hole 26 of the tracheal part 25. During this practice, the instructor can also judge the proficiency of the medical staff based on their manipulation. At the same time, the instructor can also manually intervene and guide the displacement of the front end of the tracheal tube from the inner side exposed by cutting the first teaching model 13, and make appropriate manipulation corrections based on the actual practice situation of the medical staff. Therefore, this practice method is suitable for medical staff who have initially mastered the tracheal intubation technique to simulate the actual operation process of tracheal intubation.

[0035] Third, for medical staff who have not yet mastered the tracheal intubation technique, the fully transparent second teaching aid model 14 is installed on the first teaching aid model 13 to keep the teaching aid model body 1 in a complete state for medical staff to practice. The medical staff will turn the fully transparent second teaching aid model 14 towards themselves and practice the tracheal intubation technique. The combined teaching aid model body 1 will cover the intubation teaching aid 2 and simulate the patient's oral condition in the actual operation environment. During the practice, although the medical staff and the instructor cannot manually intervene and guide the tracheal intubation, the medical staff can The instructor can still observe the displacement of the endotracheal tube in the chamber 12 in real time through the fully transparent second teaching model 14. During the practice, the medical staff can practice operating the endotracheal tube under the instructor's verbal guidance or alone to lift the collapsed arc-shaped shielding member 27 and insert it into the through hole 26 of the tracheal part 25. During this practice, since the first teaching model 13 and the second teaching model 14 obstruct the chamber 12 area, which is similar to the actual operating environment, the medical staff can repeatedly simulate the actual operating environment to practice endotracheal intubation.

[0036] Fourth, medical staff who are proficient in tracheal intubation; install the fully transparent second teaching model 14 on the first teaching model 13 to keep the teaching model body 1 in a complete state for medical staff to practice. The medical staff will turn the colored and non-transparent first teaching model 13 towards themselves and practice tracheal intubation. During the practice, the colored and non-transparent first teaching model 13 will cause a visual obstruction to the cavity 12 area. At the same time, the first teaching model 13 and the second teaching model 14 will also cause manual intervention. Obstruction, in order to simulate the actual oral condition of the patient in the actual operation environment, therefore, the medical staff needs to rely on their own proficiency in endotracheal intubation to control the endotracheal intubation to lift the collapsed arc-shaped shielding member 27 and insert it into the through hole 26 of the tracheal part 25. During the practice, the instructor can observe the cavity 12 area in real time through the fully transparent second teaching aid model 14 and judge the proficiency of the medical staff based on the manual operation. In this way, combined with the correct endotracheal intubation technique, the instructor can formulate teaching guidance tasks suitable for each stage for each practicing medical staff;

[0037] Compared with the existing intubation teaching aids 2 in hospitals, the tracheal intubation teaching aids 2 designed by the present invention can be used for practice by medical staff at all stages. During practice, medical staff can manually adjust the front end position of the tracheal cannula independently, and the instructor can also provide manual guidance or verbal guidance. During the practice process, the instructor can timely intervene and guide the medical staff's manual operation, so that medical staff can quickly master the correct manual operation of tracheal intubation, making the entire practice process of tracheal intubation efficient.

[0038] In a further preferred embodiment, referring to the attached Figure 5 and 6 As shown, the base 3 is fixedly connected to the bottom of the first teaching aid model 13, and the bottom of the second teaching aid model 14 is fixedly provided with two pillars 31, and the bottom end of each pillar 31 is fixedly provided with a slider 32;

[0039] The base 3 is provided with two slide grooves 33 adapted to the sliders 32 at the bottom ends of the two pillars 31. The spacing between the two slide grooves 33 is the same as the spacing between the sliders 32 at the bottom ends of the two pillars 31, and the same end of the two slide grooves 33 extends to the outer part of the base 3 on the base 3 in the corresponding direction of the second teaching aid model 14. The base 3 is provided with an extension groove 34 extending upward from each slide groove 33 for the movement of the two pillars 31.

[0040] When separating the second teaching aid model 14 from the first teaching aid model 13, the second teaching aid model 14 can be controlled to translate outward, so that the sliders 32 at the bottom ends of the two pillars 31 below the second teaching aid model 14 gradually move outward along the corresponding slide grooves 33 on the base 3, and until the corresponding sliders 32 are disengaged from the slide grooves 33, the disassembly of the second teaching aid model 14 is completed;

[0041] When the second teaching aid model 14 needs to be spliced ​​with the first teaching aid model 13, the sliders 32 at the bottom ends of the two pillars 31 below the second teaching aid model 14 can be inserted into the corresponding slide grooves 33 from the outside of the base 3, and then the second teaching aid model 14 is pushed toward the first teaching aid model 13 until the two are combined. The splicing combination of the second teaching aid model 14 and the first teaching aid model 13 is completed. During tracheal intubation practice, medical staff can directly control the second teaching aid model 14 by hand to prevent it from moving outward from the base 3;

[0042] By setting the slide groove 33 and the corresponding two pillars 31 and slider 32 on the base 3, the second teaching aid model 14 can be spliced ​​and combined with the first teaching aid model 13 in a translational state, so that the second teaching aid model 14 can maintain a symmetrical position with the first teaching aid model 13 after splicing, thereby preventing the second teaching aid model 14 from being misaligned with the first teaching aid model 13 after splicing, thereby preventing the insertion of the tracheal intubation through the air inlet groove 11 into the cavity 12 area.

[0043] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
