Description

Technical Field

[0001] The utility model relates to a teaching device model for intubation inside the human body, in particular to an intestinal simulation teaching model for simulating the oral cavity and the tube channel. Background Art

[0002] Intubation is a medical operation, usually referring to inserting a special pipeline or catheter into the body through the body surface and body cavities of the human body to achieve examination, treatment or other medical purposes. Intubation has a wide range of applications in medicine. For example, tracheal intubation is to insert a special endotracheal catheter through the oral cavity or nasal cavity and into the trachea through the glottis, mainly for patients who cannot breathe independently, those with severe chest and lung injuries, and those with severe lung infections; for example, gastric tube intubation is to insert a catheter into the stomach through the nasal cavity or oral cavity to achieve the purpose of treatment or nutritional support, mainly for treating diseases such as esophageal stenosis and esophageal obstruction, and providing nutritional support for patients who cannot eat. Intubation operations require long-term training (constantly learning intubation operations to improve one's own operation skills and levels), and there are relatively large risks, which are likely to cause laryngeal injuries (such as improper extrusion of the front end of the laryngoscope, which may damage the pharyngeal mucosal tissue, resulting in hematoma or bleeding) and pipeline injuries (such as slipping into the trachea, causing postoperative hoarseness and laryngeal pain, and inserting into the esophagus will cause damage to the esophageal wall, etc.). At present, intubation teaching is limited to the methods of knowledge transfer and case observation, and the teaching of medical personnel has weak practical operability, so the improvement of skill levels is limited. Content of the Utility Model

[0003] The purpose of the utility model is to solve the technical problems pointed out in the background art, and to provide an intestinal simulation teaching model for simulating the oral cavity and the tube channel, which realizes the simulation of various scenarios of intubation operations, greatly improves the practical operation efficiency and quality of medical personnel, and is conducive to quickly improving the skill levels and operation abilities of medical personnel.

[0004] The purpose of the utility model is achieved by the following technical solutions:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following further describes the utility model in detail with reference to the embodiments:

[0026] Embodiment

[0027] As Figures 1 to 6As shown in the figure, an intestinal simulation teaching model that simulates the oral cavity and tube channels includes an intubation tube and a tube channel 301. The end parts of the tube channel 301 are hermetically connected to a mouth cavity 3021 and a nasal cavity 303 respectively. A rotation monitoring device 305 is provided near the mouth airway 302 of the tube channel 301 (the rotation monitoring device 305 is simulated to be located at the position of the human laryngeal prominence, simulating the laryngeal area, and is used to train medical personnel for the left and right rotation aspiration operation of phlegm in the larynx. There is a Hall sensor 309 at the position of the rotation monitoring device 305 for position detection and judgment. The rotation monitoring device 305 can detect whether the intubation tube rotates left and right; the tube channel 301 can be a trachea, an esophagus, or a double-pass connection of the trachea and the esophagus at the position of the rotation monitoring device 305, and Hall sensors 309 are respectively arranged correspondingly). Along the length direction of the tube channel 301, a number of Hall sensors 309 for correspondingly monitoring the position of the intubation tube are arranged in sequence. The Hall sensors 309 adopt Hall sensors for detecting positions. The end part of the intubation tube for teaching simulation is electrified (i.e., with current). When the end part of the intubation tube approaches the Hall sensor 309, the Hall sensor 309 will detect a Hall voltage (when the current direction at the end part of the intubation tube is perpendicular to the magnetic field direction of the Hall sensor 309, a transverse potential difference will be generated in the direction perpendicular to both the magnetic field and the current direction. This phenomenon is called the Hall effect, and the generated potential difference is called the Hall voltage), so as to detect the position where the intubation tube for teaching simulation is inserted and detect the position of the intubation operation. As Figure 2 shown, for example, when the end part of the intubation tube is inserted into the position of the Nth Hall sensor 309, the Nth Hall sensor 309 will detect it, and it can be judged that the end part of the intubation tube is inserted into the position of the Nth Hall sensor 309.

[0028] As Figure 1 shown, the end part of the tube channel 301 is also hermetically connected to an intubation simulation pipeline 304. In order to meet the simulation teaching drills of various case situations, the intubation simulation pipeline 304 simulates a patient with a tracheostomy tube.

[0029] In some embodiments, a valve 3011 is provided inside the tube channel 301 near the mouth airway 302. The valve 3011 is made of a soft material (that is, when each soft material is closed, the valve is closed, and the soft material is also easily opened after ventilation). As Figure 1 shown, it can realize ventilation from right to left, and the intubation operation can also smoothly pass through the valve 3011.

[0030] As Figure 1 、 Figure 4As shown, the utility model further includes a head simulation model 360 and a chest simulation model 310 connected to the head simulation model 360. The head simulation model 360 and the chest simulation model 310 are in the shape of a housing for accommodating and simulating the external surface of the human body, and are generally made of silicone material with simulated skin. The mouth cavity 3021 and the nasal cavity 303 are placed in the head simulation model 360, and the tube channel 301, the rotation monitoring device 305, and the Hall sensor 309 are placed in the chest simulation model 310. The mouth cavity 3021 has a mouth airway 302 that is hermetically connected to the end of the tube channel 301, and the nasal cavity 303 has a nasal airway 3031 that is hermetically connected to the end of the tube channel 301 (the nasal airway 3031 includes a part placed in the nasal cavity 303 and a part connecting to the tube channel 301, and generally a Hall sensor 309 is also provided in the part connecting to the tube channel 301). In some embodiments, Hall sensors 309 are also correspondingly arranged in the nasal airway 3031 or / and the mouth airway 302.

[0031] See Figure 2 , a tube channel positioning seat for positioning and installing the tube channel 301 is provided inside the chest simulation model 310. The tube channel positioning seat is used for positioning the tube channel 301 and providing the installation positions of the Hall sensors 309. Each Hall sensor 309 inside the chest simulation model 310 is correspondingly fixed on the tube channel positioning seat.

[0032] As Figure 6 shown, the rotation monitoring device 305 includes a rotation detection sensor 3051 (the utility model uses an existing angle sensor or angular displacement sensor to detect the rotation angle). The rotation action input end (i.e., the detection end) of the rotation detection sensor 3051 has a rotation friction wheel 3052 located inside the tube channel 301 (in this application, a rotation friction wheel 3052 can be set at the detection input end of the angle sensor or angular displacement sensor). When the end of the intubation tube is inserted into the position of the rotation monitoring device 305, the left and right rotation and swing of the intubation tube touch the rotation friction wheel 3052 to rotate left and right so that the rotation detection sensor 3051 detects the rotation action. After the end of the intubation tube is in place, the training medical staff rotates left and right for sputum aspiration operation (to facilitate thorough aspiration, which is an operation key point). The end of the intubation tube rotates left and right and drives the rotation friction wheel 3052 to rotate left and right by friction. The rotation detection sensor 3051, as an angle sensor, the encoder inside can detect the rotation signal and output it.

[0033] In some embodiments, a further technical solution is as follows: Provide an elastic prestress technical solution for the rotating friction wheel 3052. The rotation monitoring device 305 further includes a mounting bracket 3053 and a prestress support arm 3054. The mounting bracket 3053 is installed on the internal structure of the chest simulation model 310 at the position of the rotation monitoring device 305. The end of the prestress support arm 3054 is hinged to the mounting bracket 3053 and an elastic prestress is applied through a spring 3055 installed on the mounting bracket 3053 (see Figure 6 , the mounting bracket 3053 is a U-shaped frame. The prestress support arm 3054 is hinged to the bottom end of the mounting bracket 3053. A spring 3055 is installed between the prestress support arm 3054 and the top end of the mounting bracket 3053. The spring 3055 gives an elastic force downward to the prestress support arm 3054), and the rotating friction wheel 3052 and the rotation detection sensor 3051 are correspondingly installed on the prestress support arm 3054. When the end of the intubation tube is inserted into the position of the rotation monitoring device 305, under the elastic prestress of the spring 3055, the rotating friction wheel 3052 elastically clings to the outer wall of the intubation tube, and the end of the intubation tube can also smoothly pass through the rotating friction wheel 3052. At the same time, the end of the intubation tube can also be located below the rotating friction wheel 3052 and cling to it to drive the rotating friction wheel 3052 to rotate or swing left and right. Because this is a simulation of the human larynx, there will be resistance during the process of the intubation tube passing through itself. Medical staff can make empirical judgments based on the position of the chest simulation model 310 during intubation.

[0034] As Figure 1 shown, the end of the mouth airway 302 close to the tube passage 301 is the tail end (i.e., Figure 1 the lower end of the mouth chamber 3021 close to the position of the tube passage 301), and a tongue 307 and a glossoptosis driving component 308 for driving the tongue 307 to move towards the tail end of the mouth airway 302 are movably installed inside the mouth chamber 3021. The glossoptosis driving component 308 can simulate the glossoptosis of the patient. Glossoptosis is a major problem for medical staff during intubation from the oral cavity.

[0035] In some embodiments, a further preferred technical solution is as follows: The glossoptosis driving component 308 includes a glossoptosis driving motor 3081 fixed to the inner wall of the mouth chamber 3021. A tongue internal linkage block 3082 is installed inside the tongue 307. The glossoptosis driving motor 3081 is power-connected to the end of the tongue internal linkage block 3082 through a linkage mechanism. Preferably, the linkage mechanism includes a driving swing rod and a hook-shaped linkage movably connected to the driving swing rod. The driving swing rod is fitted on the output shaft of the glossoptosis driving motor 3081, and the end of the hook-shaped linkage is connected to the end of the tongue internal linkage block 3082.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
