Description

Technical Field

[0001] The utility model belongs to the research field of medical training model technology, and particularly relates to an airway intubation practice simulation device. Background Art

[0002] Tracheal intubation is primarily used to assist patients with breathing, relieve airway obstruction, and aspirate airway secretions. If a patient requires general anesthesia, or experiences sudden respiratory arrest and inability to breathe independently, or if their airway is compressed or secretions are excessive and cannot be cleared, leading to airway obstruction, they may experience symptoms such as dyspnea and shortness of breath. Timely tracheal intubation is necessary to assist breathing and alleviate hypoxia. In existing technology, in order to emphasize avoiding errors during training and improve the accuracy of tracheal intubation, medical staff need to be trained in tracheal intubation.

[0003] Patent publication number CN219392836U discloses a simulated endotracheal intubation model for emergency training, comprising a model body, including a head, neck, and body. The front of the head features an oral cavity, including the pharynx and throat. The oral cavity also includes an upper alveolar ridge and tongue, each equipped with a pressure sensor. A simulated oral foreign body is located within the oral cavity, with a pressure sensor located at the base of the simulated oral foreign body. The body cavity houses a lung sac connected to a trachea, which communicates with the oral cavity. An air pressure sensor is located within the lung sac. A reminder is electrically connected to the tilt sensor, pressure sensor, pressure sensor, and air pressure sensor. To use the model, the simulated oral foreign body is first removed, triggering the reminder. Then, the laryngoscopy is used to dilate the trachea. Finally, when the ventilation device is connected, if a significant change in air pressure is detected within the lung sac, the reminder is triggered. Finally, the switch is pressed again to stop the timer.

[0004] However, in the above technical solution, the tongue thickness and jaw size of the model body are fixed, and cannot be applied to patients in different conditions, because the tongue thickness and jaw size of different patients are different, especially patients with hypertrophy of the tongue and small jaw. The above model cannot provide targeted training for patients with other conditions such as hypertrophy of the tongue and small jaw. The training mode is single and the learning effect is poor. Utility Model Content

[0005] The purpose of the utility model is to overcome the problems of the existing training device having a single training mode and poor learning effect.

[0006] In order to achieve the above-mentioned purpose, the technical idea adopted by the utility model is: adding an adjustment airbag to the simulated tongue body used for tracheal intubation training model, including a simulated tongue base and an adjustment airbag; wherein, the adjustment airbag is arranged on the upper surface and side of the simulated tongue body; when in use, the size of the simulated tongue can be adjusted by adjusting the air pressure inside the adjustment airbag, so that the conditions of various different patients can be simulated, there are many training modes, and the practice and learning effect is good.

[0007] Based on the above technical ideas, the technical solution adopted by this utility model is:

[0008] An airway intubation practice simulation device includes a simulation head, the simulation head includes a simulated oral cavity, and further includes:

[0009] The tongue simulator comprises a simulated tongue body and an adjustment airbag; the adjustment airbag is arranged on the surface of the simulated tongue body;

[0010] The tongue simulator is arranged in the simulated oral cavity.

[0011] To further limit the above technical solution, preferably, the regulating airbag includes: an upper regulating airbag and a side regulating airbag;

[0012] The upper regulating airbag is arranged on the upper surface of the simulated tongue body;

[0013] The side adjustment airbag is arranged on the side of the simulated tongue body.

[0014] A further limitation of the above technical solution includes: a simulated mandible, comprising a simulated mandible body and a size adjuster;

[0015] The simulated mandibular body is connected to the size adjuster.

[0016] As a further limitation of the above technical solution, the simulated mandibular body includes two symmetrically arranged arc-shaped strips.

[0017] In a further limitation of the above technical solution, the size adjuster includes a connecting block and an adjusting rod;

[0018] The connecting block is a C-shaped structure, and its two ends are respectively connected to the arc-shaped bar;

[0019] One end of the adjusting rod is connected to the connecting block, and the other end is connected to the simulation head.

[0020] As a further limitation of the above technical solution, the arc-shaped strip is a steel wire strip.

[0021] Beneficial effects of the utility model:

[0022] The utility model adds an adjusting air bag to the simulated tongue body used for tracheal intubation training model, including a simulated tongue base and an adjusting air bag; wherein, the adjusting air bag is arranged on the upper surface and side surface of the simulated tongue body; when in use, the size of the simulated tongue can be adjusted by adjusting the air pressure inside the adjusting air bag, so that the conditions of various different patients can be simulated, such as patients with symptoms such as tongue hypertrophy, with multiple training modes and good practice and learning effects.

[0023] Among them, the upper adjustment airbag can not only simulate the softness of the tongue surface, but the tongue base can also simulate the muscle strength of the tongue.

[0024] Moreover, the present invention also provides a simulated mandible, which includes a simulated mandible main body and a size adjuster. When in use, the connecting block can be moved toward the center of the simulation head through the adjusting rod, so that the arc-shaped strip used to simulate the mandible moves toward the center of the central through hole of the connecting block, so as to reduce the size of the simulated mandible, and then the adjusting rod is fixed in the toothed fixing strip, thereby adjusting the size of the simulated mandible. In this way, the effect of different mandibular sizes on the tongue can be simulated by adjusting the size of the mandible, so that it can be suitable for patients in different situations, with strong simulation and high practicality.

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Example 1

[0039] like Figure 1-4 As shown, an airway intubation practice simulation device provided by the present invention includes a simulated tongue 1 and a simulated head 3.

[0040] To facilitate observation of the proper placement of the endotracheal tube, the simulator head 3 includes a solid portion and an observation portion, which are integrally connected. Specifically, the solid portion is made of an opaque simulation material, while the observation portion is made of a transparent material, making it easier for the instructor to observe and determine whether the intubation is successful.

[0041] The simulation head 3 is equipped with a simulated oral cavity 31, which simulates the oral cavity. The simulated oral cavity 31 is an opening located near the mandible of the simulation head 1. Specifically, the simulated oral cavity 31 is connected to the simulated trachea, which in turn is connected to the simulated lungs. During actual use, the instructor can use the observation unit to confirm the trainee's successful intubation.

[0042] A simulated tongue 1 is provided inside the simulated oral cavity 31 ; the simulated tongue 1 is fixedly arranged inside the simulated oral cavity 31 near the simulated trachea.

[0043] The simulated tongue 1 comprises a simulated tongue body 11 and an adjusting airbag 12. The adjusting airbag 12 comprises an upper adjusting airbag 12a and a side adjusting airbag 12b.

[0044] Specifically, the simulated tongue body 11 is a three-layer structure. The simulated tongue 11 is integrally connected to the inner wall of the simulated oral cavity 31. The simulated tongue body 11 is composed of a double-layer sponge 11a and a support block 11b; specifically, the support block is disposed between the double-layer sponge 11a.

[0045] The upper adjustment airbag 12a is positioned above the simulated tongue body 11. A friction granular layer is provided on the surface of the upper size adjuster airbag 12a to simulate the lingual papillae on the tongue's surface. Specifically, the upper airbag 12a has a fan-shaped structure. During use, the thickness of the simulated tongue can be adjusted by inflating the upper adjustment airbag 12a to adjust its expansion level.

[0046] The side adjustment airbag 12b is set on the side of the simulated tongue body 11 and is used to adjust the length and width of the simulated tongue body 11 in the transverse direction. When in use, the lower adjustment airbag 12b can be inflated to expand the lower adjustment airbag 12b, thereby adjusting the transverse size of the simulated tongue body 11.

[0047] Specifically, the upper regulating airbag 12a is connected to the first inflation conduit 4, while the side regulating airbag 12b is connected to the second inflation conduit 5. The ends of the first and second inflation conduits 4 and 5, away from the regulating airbags, pass through the mandible of the dummy head 3 and are connected to external inflation devices to adjust the internal air pressure of the upper and side regulating airbags 12a and 12b.

[0048] It should be noted that the inflation device provided in the embodiment of the present invention is prior art, and the embodiment of the present invention does not improve on it. Example 2

[0049] Based on Example 1, the difference from Example 1 is that Figure 5-8 As shown, the airway intubation training simulator provided in this embodiment also includes a simulated mandible 2. The simulated mandible 2 includes a simulated mandible body 21 and a size adjuster 22. The simulated mandible 2 is disposed at the mandibular position of the simulated head 3 and is embedded in a receiving cavity within the simulated head 3.

[0050] The simulated mandibular body 21 includes two curved bars symmetrically arranged around the size adjuster 22. The curved bars are elastic structures, specifically, elastic steel wires. Correspondingly, a movable slot is provided in the mandibular position of the simulated head 1 to secure the curved bars.

[0051] Specifically, the two arc-shaped bars are connected via a size adjuster 22 .

[0052] The size adjuster 22 includes a connecting block 22 a and an adjusting rod 22 b .

[0053] The connecting block 22a is a C-shaped tubular structure with a through hole in the center that connects the upper and lower parts. When in use, the opposite ends of the two arc-shaped strips are respectively inserted into the through holes of the connecting block 22a. In this way, the size of the simulated mandible 2 can be adjusted by adjusting the relative position of the connecting block 22a and the arc-shaped strips.

[0054] In order to facilitate the practitioner to adjust the height of the connecting block 22a, an adjustment rod 22b is provided at both ends of the connecting block 22a, so that the practitioner can hold the adjustment rod 22b with both hands and move the adjustment rods 22b at both ends upward at the same time. The adjustment rod 22b will drive the connecting block 22a to move upward. At this time, the arc strip will retreat and enter the through hole of the connecting block 22a, simulating the lower jaw 2 to become smaller; if the adjustment rods 22b at both ends are moved downward at the same time, the adjustment rod 22b will drive the connecting block 22a to move downward. At this time, the arc strip will extend from the through hole of the connecting block 22a, simulating the lower jaw 2 to become larger, thereby realizing the adjustment of the relative position of the connecting block 22a and the arc strip.

[0055] Correspondingly, such as Figure 6 and 8As shown, a mandibular size adjustment slot 32 is provided at the mandibular position of the simulated head 3 to allow the adjustment rod 22b to slide. Specifically, the mandibular size adjustment slot 32 includes a sliding slot 32a and a toothed fixing strip 32b; and the toothed fixing strip 32b is arranged in the sliding slot 32a. When in use, the adjustment rod 22b is lifted upward from the toothed fixing strip 32b so that the adjustment rod 22b is located in the sliding slot 32a, and then the adjustment rod 22b is moved. After the size adjustment of the simulated mandibular is completed, the adjustment rod 22b is pressed toward the inside of the toothed fixing strip 32b so that the adjustment rod 22b is fixed in the toothed fixing strip 32b. At this time, the size adjustment of the simulated mandibular 2 is completed.

[0056] It should be noted that the material of the mandibular portion of the simulation head 3 provided in the embodiment of the present invention is an elastic material. Specifically, the material of the mandibular portion of the simulation head 3 is elastic rubber.

[0057] Application Case 1:

[0058] Training endotracheal intubation in patients with tongue hypertrophy includes the following steps:

[0059] Step 1: Inflate the upper adjustment airbag 12a and the side adjustment airbag 12b respectively through the inflation device, so that the simulated tongue 1 is in a simulated tongue hypertrophy state;

[0060] Step 2: Place the simulated head 3 horizontally, with the neck supported by a pillow, so that the three axes of the mouth, pharynx, and larynx of the simulated head 3 are aligned; and the contact person stands on the simulated head 3 so that the xiphoid process is flush with the patient's head;

[0061] Step 3: Open the airway by tilting the head back and lifting the chin. Secure the mask with the left hand using EC technique. Evenly squeeze the breathing bag with the right hand. Administer 100% oxygen for 2 to 3 minutes at 10 to 12 breaths / minute.

[0062] Step 4: Use the right thumb and index finger to cross open the simulated oral cavity 31. Hold the laryngoscope in your left hand and insert it from the right corner of the mouth. Push the tongue to the left and advance the laryngoscope along the midline to expose the patient's uvula and epiglottis. Place the front end of the curved laryngoscope in the epiglottal valley (place the straight laryngoscope below the epiglottis). Pull the laryngoscope forward and upward at approximately 45 degrees, gently lifting the epiglottis to expose the glottis.

[0063] Step 5: Insert the endotracheal tube from the right corner of the mouth with the pen in the right hand. Aim the tube at the glottis and insert it into the trachea. Once the cuff enters the glottis, have an assistant remove the stylet and continue advancing the tube for 2-3 cm. The tip of the tube should be 20-24 cm away from the incisors.

[0064] Step 6: Place the dental pad, inflate the cuff, and remove the laryngoscope;

[0065] Step 7: Confirm the position of the tube. Squeeze the breathing bag to see symmetrical rise and fall of the chest on both sides. Auscultate the breath sounds on both sides to make sure that the tube is in the trachea.

[0066] Step 8: Use tape to fix the catheter and dental pad. The tape should be long enough to reach the mandibular angle and should not stick to the lips.

[0067] During the trainee's practice, the instructor observes the trainee's operating steps and status from the observation portion of the simulation head 3 and determines whether the tracheal intubation is successful.

[0068] Application Case 2:

[0069] Intubation training for patients with small jaws includes the following steps:

[0070] Step 1: Lift the adjustment rod 22b upward from the toothed fixing clip 24b so that the adjustment rod 22b is located in the sliding groove 32a. Then, hold the adjustment rod 22b with both hands. Under the action of the adjustment rod 22b, the connecting block 22a moves closer to the top of the simulation head 3, so that the arc strip passes through the central through hole of the connecting block 22a, thereby shortening the relative distance between the arc strip and the connecting block 22a.

[0071] Step 2: Press the arc strip downwards so that it is clamped in the recess of the toothed fixing strip 24b to secure the arc strip. At this point, the mandibular size adjustment is complete.

[0072] Step 3: Practice endotracheal intubation. The specific implementation of this step is the same as steps 2 to 8 in Application Case 1 and will not be repeated here.

[0073] During the trainee's practice, the instructor observes the trainee's operating steps and status from the observation portion of the simulation head 3 and determines whether the tracheal intubation is successful.

[0074] The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
