Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a tracheotomy and intubation training simulator. Background Art

[0002] In the field of medical training, tracheotomy and intubation techniques are one of the key skills that medical personnel must master. The proficiency and accuracy of its operation are directly related to the patient's life safety. Currently, the most common tracheotomy and intubation training tools on the market are mainly airway management models with uniform specifications. Although these models can provide medical personnel with basic intubation training scenarios and help them familiarize themselves with the intubation process and operation techniques to a certain extent, they have significant shortcomings in simulating real clinical environments.

[0003] In actual clinical practice, patients’ tracheal conditions are complex and varied, with various abnormalities such as tracheal stenosis, tracheal deviation, and tracheal softening. However, the existing airway management models with unified specifications cannot effectively simulate these complex and changeable tracheal abnormalities. This leads to a large difference between the scenarios that medical staff encounter in daily training and the situations they face in actual clinical practice. When they encounter patients with tracheal abnormalities in their actual work, they may not be able to perform tracheotomy and intubation operations quickly, accurately, and effectively due to lack of targeted training, which in turn affects the patient’s treatment effect and even endangers the patient’s life. Therefore, the development of a training simulator that can simulate a variety of tracheal abnormalities has important practical significance and clinical value, and is urgent to improve the emergency response capabilities and clinical treatment levels of medical staff. Summary of the Invention

[0004] Technical problems solved In view of the deficiencies in the prior art, the present invention provides a tracheotomy and intubation training simulator, which solves the problem that traditional tracheotomy and intubation training models cannot simulate complex tracheal abnormalities.

[0005] Technical Solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a tracheotomy and intubation training simulator, comprising a simulator body, an airway management model disposed within the simulator body, the airway management model being used to perform simulated tracheal intubation, artificial respiration mask ventilation, oral airway liquid and foreign body suction, and cricoid cartilage compression operation training, the simulator body further being provided with an adjustable mechanism, the airway management model being disposed throughout the adjustable mechanism; The adjustable mechanism includes an outer connecting ring, an adjusting frame and an inner connecting ring, an inner supporting frame is fixedly provided at the bottom of the adjusting frame, a rotating frame is rotatably provided at the upper end of the inner supporting frame, a connecting tube is fixedly provided at the middle position inside the rotating frame, a plurality of elastic curved plates are fixedly provided inside the connecting tube, a rotating groove is provided at the upper end of the adjusting frame, and an adjusting groove is provided inside the rotating groove.

[0006] Preferably, a threaded sleeve is rotatably provided on a side of the outer connecting ring close to the adjusting frame, and a threaded disk is fixedly provided on a side of the inner connecting ring close to the adjusting frame.

[0007] Preferably, a connecting thread is fixedly provided on one side of the adjusting frame, a connecting drum is rotatably provided on the other side of the adjusting frame, and a plurality of anti-sliding blocks are fixedly provided on the outside of the connecting drum.

[0008] Preferably, a plurality of the adjusting frames are provided, and the plurality of connecting threads are respectively threadedly connected to the inside of adjacent connecting drums.

[0009] Preferably, two sliding frames are slidably provided inside the rotating frame, a stabilizing slide bar is slidably provided between the two sliding frames, and a reset spring is fixedly connected between the two sliding frames at one side close to the stabilizing slide bar.

[0010] Preferably, limiting columns are fixedly provided on opposite sides of the two sliding frames, and limiting holes are provided through the front and rear positions of the rotating frame. The two limiting columns are respectively slidably provided inside the two limiting holes and are snap-fitted into the inside of the adjustment slot.

[0011] Working Principle: To simulate tracheotomy and intubation training, the tracheotomy manikin is first installed within the adjustable mechanism. To simulate tracheal abnormalities, the user sets the number of adjustment frames according to the training plan. The user connects the required number of adjustment frames using threaded connectors and rotating cylinders to form a complete adjustable structure. The outermost adjustment frames are connected to the inner and outer connecting rings to determine the number of abnormalities in the simulated trachea. Next, the trachea in the tracheotomy manikin is inserted through each connecting cylinder. To simulate tracheal abnormalities, the operator presses the two sliding frames. A stabilizing rod slides between the two frames, and a return spring is fixedly attached near the rod. This press compresses the return spring. Simultaneously, the retaining post on the sliding frame, which is originally engaged within the adjustment slot, is released by pressing the sliding frame. Subsequently, the rotating frame rotates, and the connecting cylinder, fixed in the center of the frame, rotates with it, causing the trachea passing through it to deflect. Because multiple elastic curved plates are fixed inside the connecting tube, the trachea will be squeezed by the elastic curved plates during the displacement process, resulting in extrusion deformation, simulating abnormal conditions such as stenosis and twisting inside the trachea, providing medical staff with a highly simulated tracheotomy and intubation training environment, helping them improve related operational skills.

[0012] Beneficial effects The present invention provides a tracheotomy and intubation training simulator, which has the following beneficial effects: 1. The present invention provides a tracheotomy and intubation training simulator. This tracheotomy and intubation training simulator achieves flexible setting of the number of abnormal parts inside the trachea by providing a freely combinable number of adjustment frames. Multiple adjustment frames can be connected in sequence by means of connecting threads and connecting cylinders, and the two adjustment frames located on the outermost side can also be connected to the inner side of the outer connecting ring and the inner connecting ring, respectively. This unique design allows users to easily adjust the number of abnormal parts in the simulated trachea according to actual training needs, thereby providing medical personnel with more diverse and realistic training scenarios, greatly enhancing the targetedness and practicality of training.

[0013] 2. The present invention provides a tracheotomy intubation training simulator. During use, the trachea in the airway management model will pass through a specified number of connecting tubes. By pressing the two sliding frames, the limit column is moved out of the adjustment slot, and then the rotating frame is rotated, the connecting tube will cause the trachea to deflect, and the trachea will also be squeezed and deformed due to the action of the connecting tube. This series of operations can accurately simulate abnormal conditions such as stenosis and twisting inside the trachea, allowing medical staff to truly feel the difficulty and key points of intubation under abnormal tracheal conditions during training, effectively improving their ability to deal with complex tracheal conditions in actual clinical practice.

DETAILED DESCRIPTION

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figure 1-5 As shown, an embodiment of the present invention provides a tracheotomy intubation training simulator, including a simulator body 2, wherein an airway management model is provided inside the simulator body 2, and the airway management model is used to perform simulated tracheal intubation, artificial respiration mask ventilation, oral airway liquid foreign body suction and cricoid cartilage compression operation training; Specifically, in the above-mentioned specific embodiment, the manikin 2 provides a carrier for the airway management model. The airway management model is constructed according to the physiological characteristics of the human trachea and related respiratory structures. Through specific structural design and materials, it simulates the actual operational experience of tracheal intubation, such as touch and resistance. In artificial respiration mask ventilation training, it can simulate the process of gas entering the airway. Oral airway liquid foreign body suction training can be simulated by internal simulated liquid and related suction structures. Cricoid cartilage compression operation training is based on the simulation of related structures of the human larynx to achieve operational feedback. Ultimately, it provides medical personnel with a comprehensive training platform that can comprehensively cover a variety of common and important airway management operation training, allowing them to complete multi-faceted skill training on a single manikin, improving training efficiency and saving training resources.

[0018] The interior of the manikin 2 is also provided with an adjustable mechanism 1, and the airway management model is arranged throughout the interior of the adjustable mechanism 1; Specifically, in the above-mentioned specific embodiment, the adjustable mechanism 1, through its specific structural design, can adjust the position and shape of the trachea part in the airway management model running through it, simulate the abnormal conditions of the trachea, break the limitation of the single specification of the traditional airway management model, and enable the training simulator to simulate a tracheal state that is more in line with the actual complex clinical situation, thereby enhancing the authenticity and effectiveness of the training and allowing medical staff to adapt in advance to various tracheal conditions that may be encountered in actual work.

[0019] like Figure 2-5 As shown, the adjustable mechanism 1 includes an outer connecting ring 101, an adjusting frame 102 and an inner connecting ring 103. An inner support frame 115 is fixedly provided at the bottom of the adjusting frame 102. A rotating frame 112 is rotatably provided on the upper end of the inner support frame 115. A connecting tube 113 is fixedly provided at the middle position inside the rotating frame 112. A plurality of elastic curved plates 110 are fixedly provided inside the connecting tube 113. A rotating groove 119 is provided at the upper end of the adjusting frame 102, and an adjusting groove 118 is provided inside the rotating groove 119. Specifically, in the above-described embodiment, the outer connecting ring 101, the adjustment frame 102, and the inner connecting ring 103 collectively constitute the main frame of the adjustable mechanism 1, while the inner support frame 115 provides support and a rotational base for the rotating frame 112. When the tracheal state needs to be adjusted, the rotating frame 112 is rotated, which drives the connecting tube 113 to rotate. The elastic curved plate 110 within the connecting tube 113 exerts a force on the trachea passing through the connecting tube 113. Due to the elasticity of the elastic curved plate 110, the trachea can be subjected to varying degrees of extrusion deformation. The rotation slot 119 and the adjustment slot 118 cooperate with the rotating frame 112 and subsequent limiting structures to limit and adjust the rotation angle of the rotating frame 112. This structural design cleverly utilizes the synergistic effect of the rotating frame 112, the connecting tube 113, and the elastic curved plate 110 to accurately simulate the extrusion deformation of the trachea in different directions and degrees. The adjustment process is relatively flexible and controllable, providing strong support for simulating various tracheal abnormalities.

[0020] A threaded sleeve 104 is rotatably provided on one side of the outer connecting ring 101 close to the adjusting frame 102, a threaded disc 105 is fixedly provided on one side of the inner connecting ring 103 close to the adjusting frame 102, a connecting thread 114 is fixedly provided on one side of the adjusting frame 102, and a connecting rotating cylinder 117 is rotatably provided on the other side of the adjusting frame 102. A plurality of anti-sliding blocks 116 are fixedly provided on the outside of the connecting rotating cylinder 117. The adjusting frame 102 is provided with multiple connecting threads 114, which are respectively threadedly connected to the inside of adjacent connecting rotating cylinders 117; Specifically, in the above-described embodiment, the threaded sleeve 104 on the outer connecting ring 101 cooperates with the connecting thread 114 on the adjustment frame 102, and the threaded disc 105 on the inner connecting ring 103 can also connect to the adjustment frame 102, thereby achieving a secure connection between the adjustable mechanism 1, the simulator 2, and the airway management model. Multiple adjustment frames 102 are sequentially threadedly connected via the connecting threads 114 and the connecting cylinder 117. When the connecting cylinder 117 is rotated, the relative positions of the adjustment frames 102 can be fine-tuned due to the transmission effect of the threads. The anti-sliding block 116 facilitates the operator's rotation of the connecting cylinder 117. Ultimately, on the one hand, a stable and adjustable connection is achieved between the various components of the adjustable mechanism 1, ensuring structural stability during the simulation process. On the other hand, the number of adjustment frames 102 can be freely combined according to training needs, thereby flexibly setting the number of abnormal locations within the trachea, greatly enriching the scenarios and difficulty levels of simulation training.

[0021] Two sliding frames 107 are slidably provided inside the rotating frame 112. A stabilizing slide bar 106 is slidably provided between the two sliding frames 107. A return spring 111 is fixedly connected between the two sliding frames 107 on one side close to the stabilizing slide bar 106. Limiting posts 109 are fixedly provided on opposite sides of the two sliding frames 107. Limiting holes 108 are provided through the front and rear positions of the rotating frame 112. Two limiting posts 109 are slidably provided inside the two limiting holes 108 and are clamped into the inside of the adjustment slot 118. Specifically, in the above embodiment, when the angle of the rotating frame 112 needs to be adjusted, the two sliding frames 107 are pressed, the stabilizing slide bar 106 acts as a guide, the return spring 111 is compressed, and the limiting post 109 moves out of the adjustment slot 118. At this time, the rotating frame 112 is rotated. After rotating to the appropriate angle, the sliding frame 107 is released, the return spring 111 rebounds, and pushes the sliding frame 107 to re-engage the limiting post 109 in the adjustment slot 118, thereby limiting and fixing the rotating frame 112. This structure provides a convenient and reliable limiting method for the rotation adjustment of the rotating frame 112. The operator can easily control the rotation and fixation of the rotating frame 112, thereby accurately simulating different degrees of offset and deformation of the exhaust pipe. At the same time, it ensures that the rotating frame 112 does not rotate arbitrarily during the simulation process, ensuring the accuracy and stability of the simulation effect.

[0022] In the adjustable mechanism 1 of the present invention, the basic structure and corresponding symptoms are as follows: External connecting ring 101: Designed with an outer diameter of 50mm and an inner diameter of 45mm, it is made of high-strength aluminum alloy and anodized for enhanced wear and corrosion resistance. It primarily connects the adjustable mechanism 1 to the manikin body 2, ensuring the entire adjustable mechanism 1 is securely mounted within the manikin.

[0023] Adjustment frame 102: A single adjustment frame 102 is rectangular, 80mm long, 60mm wide, and 50mm high, and is also made of aluminum alloy. A connecting thread 114 with a thread specification of M8×1.25 is fixed on one side of the adjustment frame 102; a connecting drum 117 with an outer diameter of 20mm and an inner diameter of 12mm is rotatably provided on the other side. The connecting drum 117 has eight anti-slip blocks 116 with a height of 2mm evenly distributed on the outside. The adjustment frames 102 are connected sequentially through the connection of the connecting threads 114 and the connecting drum 117. Each adjustment frame 102 simulates a symptom of an abnormality within the trachea, such as mild tracheal stenosis or local mild torsion. Typically, 2-8 adjustment frames 102 can be connected in series according to training needs to simulate tracheal abnormalities of varying complexity. Up to 10 adjustment frames 102 can be connected in series to cope with extremely complex simulation scenarios.

[0024] Inner connecting ring 103: The inner connecting ring 103 has an outer diameter of 48 mm and an inner diameter of 43 mm, and is made of the same material as the outer connecting ring 101. Its function is to connect the adjustable mechanism 1 with the trachea part of the airway management model, ensuring that the trachea is stably inserted into the adjustable mechanism 1.

[0025] Inner support frame 115: Made of stainless steel, 30mm high, the inner support frame 115 is fixed to the bottom of the adjustment frame 102 with four M4 screws. It provides a stable support and rotation base for the rotating frame 112, ensuring the stability of the rotating frame 112 during adjustment.

[0026] Rotating frame 112: Rotating frame 112 is U-shaped, 50mm long, 40mm wide, and 35mm high. It is injection-molded from engineering plastic, offering excellent toughness and strength. A connecting tube 113 is fixed in the center of rotating frame 112, and internal support bracket 115 allows for 360° rotation.

[0027] Connecting tube 113: Connecting tube 113 has an outer diameter of 25mm and an inner diameter of 20mm. It is made of medical-grade silicone, which is soft and elastic. Six elastic curved plates 110 are evenly distributed along the circumference of connecting tube 113. Each elastic curved plate 110 is 15mm long, 5mm wide, and 2mm thick, and is made of the same material as connecting tube 113. When the rotating frame 112 is rotated, connecting tube 113 rotates accordingly, and the internal elastic curved plates 110 exert a squeezing effect on the trachea passing through connecting tube 113, simulating symptoms such as tracheal stenosis and twisting. This system can simulate adjustment of the tracheal diameter by 20%-50% from its original value. For example, if the initial tracheal inner diameter is 20mm, a reduction to 10-16mm can be simulated to correspond to varying degrees of tracheal stenosis. The rotating frame 112 has a rotation angle range of 0-180°, simulating tracheal deviation and twisting in different directions.

[0028] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
