[0058] In order to make the purpose, technical scheme and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0059] When a patient has no spontaneous respiration, establishing a smooth and stable airway for ventilation is the first step of all emergency measures. It is widely used in anesthesia department, emergency department, ICU, various wards and various emergency scenes outside the hospital.

[0060] Visual light rod (also known as visual hard mirror) is a flexible metal catheter, the front end is equipped with a light source and a camera, the tail is connected with a battery and (or no) switch. As a non-emergency airway tool, the visual light rod has the advantages of simple operation, high success rate, safe intubation, and few complications. When intubating the visual light rod, as long as the visual light rod is bent into the appropriate shape, the head and neck do not need to be cooperated, and the principle of light transmission through the soft tissue of the neck is used. As long as the light spot is seen at the cricothyroid membrane, the tracheal tube is successfully placed into the trachea. When difficulties are encountered, in addition to rechecking the bending length and angle of the visual light rod, methods such as supporting the lower jaw, lifting the tongue, adjusting the head position appropriately, or using a laryngoscope to assist can effectively improve the success rate of intubation. The visual light rod is located in the catheter and does not directly contact the mucosa of the mouth and pharyngeal cavity. As long as the upper respiratory tract anatomy is familiar and the operation is gentle, complications are not easy to cause. The influence of blood and secretions does not need to be considered.

[0061] In the teaching of the visual light rod, the holding method of the mirror body, the precise control of the visual field level forward, backward, left and right rotation, up and down and left and right swing are the most basic operations, which are the skills that every practitioner should master first. At present, there is no non-anatomical teaching mold based on the visual light rod training on the market. The general anatomical tracheal intubation teaching mold is not suitable for the training method of the visual light rod, so the training effect is limited.

[0062] Therefore, as shown in Figure 1 , the embodiment of the present application provides a visual light rod control training box, which first proposes a visual light rod control training box, a non-anatomical teaching mold based on the visual light rod training, which fills the gap in the current market. According to the visual light rod control training box provided by the embodiment of the present application, the J-shaped channel is arranged to simulate the tracheal catheter, which can train the method, feeling and operation stability of the visual light rod from the oral cavity to the supraglottic path, wherein the operation stability refers to avoiding unnecessary touching of the lateral wall; the multi-hole body is arranged to simulate the multi-angle direction and size of the trachea, which can train the control method of the student using the visual light rod to enter the glottis and intubate. Therefore, a non-anatomical teaching mold based on the visual light rod training is provided, so that the student can practice targetedly to obtain the real experience of using the visual light rod for tracheal intubation.

[0063] Now referring to Figure 1 , it is a side view of the overall structure of a visual light rod control training box according to an embodiment of the present application. Figure 1. The present embodiment is used to provide a visual light wand manipulation training box, which is a non-anatomical teaching mold specifically used for visual light wand training, and allows trainees to quickly and efficiently master the technique, feel and operational stability of the visual light wand. Specifically, the visual light wand manipulation training box provided in this embodiment includes: a box body 10, a slot 24 extending along the first direction X is provided on the top of the box body 10; a J-shaped channel 26, the J-shaped channel 26 is provided in the box body 10 and can move along the slot 24; a porous body, provided in the box body 10; wherein, the projection of the outlet of the J-shaped channel 26 in the first direction X is located within the projection range of the porous body along the first direction X, and the outlet of the J-shaped channel 26 and the orifice of the porous body are arranged relative to each other along the first direction X.

[0064] Here, the box can be a cube, specifically a rectangular parallelepiped or a cube, but the present application is not limited thereto.

[0065] Here, the J-shaped channel is set up to train the technique, feel and operational stability of inserting the visible light stick into the path from the oral cavity to the supraglottis, wherein operational stability refers to avoiding unnecessary touching of the side wall. The J-shaped channel can be a simulated oral 3D space, but the present application is not limited thereto. The J-shaped channel 26 is a tubular strip with a length of 8 to 16 cm, and its cross-section is a rectangle with a length of 4 to 8 cm and a width of 1 to 3 cm based on the length and width of the lips of a normal person. The strip is bent, and the curvature simulates the physiological curvature of a normal person, so that the outlet is located in the first direction X and the inlet is located in the second direction Y.

[0066] Here, the material of the J-shaped channel can be EVA (ethylene-vinyl acetate copolymer) material with toughness and elasticity, or it can be a soft-hard composite material to simulate the different hardness of the soft palate and hard palate under physiological conditions.

[0067] Here, the outlet of the J-shaped channel 26 is opposite to the hole of the porous body along the first direction X, which means that the outlet of the J-shaped channel 26 is opposite to the hole of the porous body along the first direction X, so that the visible light rod can enter the hole of the porous body from the outlet of the J-shaped channel 26.

[0068] Furthermore, if Figure 1 As shown, the entrance of the J-shaped channel 26 and the slot 24 are arranged opposite to each other along the second direction Y. The entrance of the J-shaped channel 26 and the slot 24 are arranged correspondingly, so that the visible light wand has the largest movement range along the second direction Y after entering the J-shaped channel 26, providing the trainees with the largest range of operating environment.

[0069] Here, the inlet of the J-shaped channel 26 and the slot hole 24 are arranged opposite to each other along the second direction Y, which means that when the inlet of the J-shaped channel 26 moves along the second direction Y, the inlet of the J-shaped channel 26 and the slot hole 24 are opposite to each other along the second direction Y, or Figure 1As shown, the entrance of the J-shaped channel 26 is in the slot hole 24, which facilitates the student to operate the visual light rod in the maximum range.

[0070] Specifically, as shown in Figure 1 the slot hole 24 is an oblong shape, and the diameter of the entrance of the J-shaped channel 26 is ≤ the width of the slot hole 24. The slot hole 24 is sized to be 6-12 cm long and 4-8 cm wide, thereby providing the student with an operating environment for moving the visual light rod in the J-shaped channel in the maximum range. The shape of the slot hole is not limited in the present application, and can also be rectangular, etc.

[0071] Further, as shown in Figure 1 the multi-hole body is a multi-tube type channel 30, which includes a plurality of tube type channels arranged in parallel along a first direction X, for providing a plurality of types of tube type channel configurations and providing a plurality of training angles.

[0072] Specifically, the tube type channel is used to simulate the trachea, and a plurality of tube type channels of different orientations are arranged to simulate the physiological differences and individual differences of the human trachea.

[0073] Here, the multi-hole body is arranged to train the student to use the visual light rod to enter the glottis and perform catheterization.

[0074] Here, the tube type channel simulates the variable glottis and trachea position in clinical practice, and its diameter is consistent with the normal trachea. The length is selected to be sufficient to complete the catheterization training, about 3-7 cm.

[0075] Further, as shown in Figure 1 the center line of the multi-tube type channel 30 formed by extending along a second direction Y is perpendicular to the center line of the slot hole 24 along the first direction X and is in the same plane, which can provide the visual light rod with the maximum activity range and provide as many angle training methods as possible, so that the visual light rod can reach the entrances of all tube type channels after entering the J-shaped channel 26.

[0076] Here, the multi-tube type channel 30 can be arranged regularly or irregularly.

[0077] Further, the box body 10 is provided with a guide structure on the top along the first direction X, which is used to guide the movement of the J-shaped channel 26 along the slot hole 24, and can realize the guiding effect of the J-shaped channel 26 and control the movement direction of the J-shaped channel, as shown in Figure 1 the guide structure is a track, which can also be convex, and the movement range of the J-shaped channel is limited to the first direction by the track, so that the student can perform forward and backward operations and quickly master the basic movements of the visual light rod.

[0078] Further, the track and the J-shaped channel 26 are movably connected through a connecting part, specifically, as shown inFigure 1 and Figure 3 As shown, the connecting component includes rollers (including a left roller 22A and a right roller 22B) that can roll along the track and connecting rods (including a left connecting rod 23A and a right connecting rod 23B) connected between the J-shaped channel 26 and the rollers, so that the J-shaped channel 26 moves on the track (including the left roller track 21A and the right roller track 21B) along the first direction X by rolling and is suspended inside the box 10; Figure 4 As shown, the connecting component includes a slider (including a left slider 22C and a right slider 22D) that can slide along the track and a connecting rod (including a left connecting rod 23A and a right connecting rod 23B) connected between the J-shaped channel 26 and the slider, so that the J-shaped channel 26 moves on the track (including the left slider track 21C and the right slider track 21D) along the first direction X by sliding and is suspended inside the box 10.

[0079] Here, there is a certain friction between the left roller 22A and the right roller 22B and the left roller track 21A and the right roller track 21B respectively. When the trainee slightly applies a certain pressure to the J-shaped channel through the visible light stick, the roller can be rolled.

[0080] Here, there is a certain friction between the left slider 22C and the right slider 22D and the left slider track 21C and the right slider track 21D respectively. When the trainee slightly applies a certain pressure to the J-shaped channel through the visible light wand, the slider can slide.

[0081] Furthermore, if Figure 2a and Figure 2b As shown, the connecting rod and the J-shaped channel 26 are connected by a telescopic spring (including a left telescopic spring 25A and a right telescopic spring 25B), and a telescopic spring design is adopted, such as Figure 2b As shown, the J-shaped channel 26 can move downward (along the second direction Y) when it is under pressure, and automatically return to its original position when the pressure disappears. After the visible light wand enters the J-shaped channel 26, the visible light wand moves downward along the J-shaped channel 26 when the J-shaped channel 26 is under pressure, so that the visible light wand can enter the tubular channels at different positions along the second direction Y, providing students with multi-directional training angles and helping them master the basic operations of the visible light wand as soon as possible.

[0082] Furthermore, the track is provided with a stopper (not shown) for positioning the J-shaped channel as it moves along the slot 24. The stopper is used to limit the further movement of the roller or slider, which can be used to demonstrate the trainee's precise operation of the visual light wand in complex situations. For example, the stopper can be similar to a buffer zone on the road, allowing the rollers 22A and 22B or the sliders 22C and 22D to be fixed in different positions.

[0083] Furthermore, if Figure 1 、Figures 5 to 7 As shown, the multi-tube passage 30 includes 21 tube passages, the tube passage has a diameter of 1-1.5 cm, and the size of the tube passage is set to be the same as the clinical actual size of the trachea, so that the multi-tube passage can truly simulate the size of the operating environment of the human body.

[0084] Here, the 21 tube passages are arranged in an arithmetic sequence from top to bottom, the top layer has one tube passage, and the bottom layer has 9 tube passages, and the length of the side of the resulting triangle is 1.5 times the width of the normal human piriform fossa.

[0085] Here, the bottom of the multi-tube passage 30 is numbered with numbers or letters, which are used to mark the position of each tube passage, and the numbers or letters serve as markers for identifying the airway and esophagus by the visible light wand. When the visible light wand detects the label, it is considered that the passage is the trachea. At different positions, other tube passages can be replaced to simulate different tracheal states in real situations. For example, among the 21 tube passages, 8 tube passages simulate the real anatomical structure, and these 8 tube passages can be different combinations of normal or abnormal tube passages, and the remaining 13 are only used for training techniques at different positions. For abnormal tube passages, for example, a block can be placed inside the multi-tube passage 30 to simulate a tumor.

[0086] Further, as shown in Figure 1 , Figures 5 to 7 , the multi-tube passage 30 is projected as an equilateral triangle in a plane perpendicular to the first direction X. The projection is set to be a triangle, so that the length of each side of the triangle is 1.5 times the width of the normal human piriform fossa, which conforms to the actual operating environment.

[0087] Here, the projection of the multi-tube passage in a plane perpendicular to the first direction can be a regular polygon, such as a triangle, square, pentagon, hexagon, etc., or an irregular polygon, and the present application is not limited thereto.

[0088] Further, as shown in Figure 1 and Figure 2a , Figure 2b , the multi-tube passage 30 is provided with a multi-tube passage base 31 at the bottom, and the multi-tube passage base 31 is installed on the side wall of the box body 10 and can drive the multi-tube passage 30 to rotate relative to the side wall. By rotating, different use environments can be configured for students, providing multi-directional training angles; at the same time, the cross section is a triangle, and rotating the multi-tube passage 30 can form a square visible light wand operating range, which increases the training activity range of the visible light wand under the premise of using fewer tube passages, and facilitates the students to quickly master the operation skills of the visible light wand.

[0089] Further, as shown in Figure 1 , Figure 2a , Figure 2b、 Figures 5 to 7 As shown, the side wall 11 of the box 10 is detachable relative to the box 10, and the detachable arrangement facilitates replacement of the multi-tube type channel 30 with a tube type channel of a different internal environment, for example, obstacles can be added in some tube type channels, which simulate tumors, increase the diversity of the training environment, and provide multi-angle training angles, and can simulate complex situations of various real cases.

[0090] Further, as shown in Figure 2a 、 Figure 2b As shown, the rotating disc 32 is connected with the multi-tube type channel base 31 through a bearing to form a rotating pair, wherein the inner ring of the bearing is connected with the multi-tube type channel base, and the outer ring of the bearing is connected with the rotating disc. The rotating disc can rotate under the action of force, thereby driving the multi-tube type channel to rotate, providing various training angles for the trainee and exercising the trainee's operation method and feeling.

[0091] Further, the multi-tube type channel base 31 is provided with a mounting hole (not shown in the figure) for mounting the multi-tube type channel 30. The mounting hole can be marked with numbers or letters for multiple tube type channels, or a sticker can be pasted on the mounting hole. The application is not limited thereto.

[0092] The following will be described in detail in combination with Figures 1 to 7 The trainee first needs to bend the operation part of the visible light rod to the bending degree of the J-shaped channel in

[0093] The trainee first needs to bend the operation part of the visible light rod to the bending degree of the J-shaped channel in Figure 2a 、 Figure 2b The application can be provided with a projection drawing of the J-shaped channel on the outer side wall of the visible training box to provide the bending standard for the trainee. The trainee inserts the visible light rod meeting the bending standard along the entrance of the J-shaped channel and passes out of the J-shaped channel, and performs the tube type channel in the specified order. At this time, the trainee applies pressure to the J-shaped channel through the visible light rod, and the J-shaped channel can move with the visible light rod.

[0094] For example, the specified order is 1, 4, 13, 16, and 21, and the specific operation is as follows:

[0095] (1) The trainee applies pressure to the J-shaped channel through the visible light rod, moves the J-shaped channel along the track to the direction close to the tube type channel, and directly inserts the visible light rod into the tube type channel marked with 1;

[0096] (2) the student applies pressure to the J-shaped channel with the visual light stick, moves the J-shaped channel along the track in a direction away from the tubular channels, causing the visual light stick to exit the tubular channel labeled 1, moves the J-shaped channel along with the visual light stick in a second direction downward to the entrance of the tubular channel labeled 5 by the retractable spring, translates the visual light stick in a third direction left in the J-shaped channel to the entrance of the tubular channel labeled 4, and inserts the visual light stick into the tubular channel labeled 4;
