Technical Field

[0001] The present application relates to the technical field of medical devices for anesthesia, and in particular to an anesthesia airway opening auxiliary device and a control method thereof. Background Art

[0002] Anesthesia airway opening assist devices are a series of devices or tools used to help open and maintain the patient's airway during anesthesia.

[0003] In the related art, anesthesia airway opening assist devices usually open the airway by tilting the patient's head back, but this is not suitable for patients with neck injuries. Therefore, medical staff need to use the jaw support method to continuously open the airway of patients with neck injuries, which is very laborious. Summary of the invention

[0004] The embodiment of the present application provides an anesthesia airway opening assist device and a control method thereof, which can improve the technical problem in the related art that it is laborious and occupies human resources for medical staff to continuously open the airway of a patient with neck injury during anesthesia.

[0005] In a first aspect, an embodiment of the present application provides an anesthesia airway opening assist device, comprising: a first fixing part, the first fixing part comprising a height adjustment device and a plurality of first fixing devices, the first fixing device being arranged on the height adjustment device, the height adjustment device being used to support the user's head and adjust the height of the user's head, the height adjustment device having a first contact surface for contacting the user's head; the first fixing device being used to abut and move the user's lower jaw to open the airway; a second fixing portion rotatably disposed on the height adjustment device, the second fixing portion being used to fix the neck of the user, the second fixing portion having a second contact surface for contacting the neck of the user; and a third fixing portion, rotatably disposed on the second fixing portion, and used to be fixed to the upper body of the user; When the height adjustment device lowers the height of the user's head, the height adjustment device and the second fixing part rotate relative to each other, so that the first contact surface is transformed from being parallel to the second contact surface to an angle between the first contact surface and the second contact surface being less than 180 degrees, thereby allowing the user's head to tilt back to open the airway.

[0006] The anesthesia airway opening assist device provided in the embodiment of the present application is fixed to the upper body of the patient through a third fixing part, and the height of the height adjustment device is adjusted so that the head of the patient in a lying state can be supported by the height adjustment device, and the neck can be supported by the second fixing part, and the neck of the patient is fixed by the second fixing part. Then, the first fixing device is used to support the patient's lower jaw and drive the patient's lower jaw away from the patient's neck, so that the position of the lower teeth is higher than the upper teeth, so that the patient's tongue root and epiglottis cartilage (a cartilage structure located behind the tongue root, used to close the larynx to prevent food from entering the airway) leave the front wall of the larynx, thereby ensuring that the airway is unobstructed, and at the same time avoiding the problem of medical staff needing to lift the patient's lower jaw and support the patient's neck for a long time, resulting in a waste of human resources. Furthermore, medical staff can adjust the height adjustment device to lower the height of the patient's head according to the patient's on-site situation and the degree of airway opening, so that the height adjustment device and the second fixing part can rotate relative to each other and the angle formed between the first contact surface and the second contact surface is less than 180 degrees, thereby allowing the patient's head to tilt back to further open the airway. Therefore, by adjusting the height adjustment device as needed, the degree to which the patient's head tilts back can be adjusted, thereby adjusting the degree of airway opening. In this process, since the second fixing part supports and fixes the patient's neck, it can avoid moving the patient's body to cause secondary injury to the patient when further opening the airway. This is especially suitable for patients with neck injuries.

[0007] In a second aspect, an embodiment of the present application provides a method for controlling an anesthesia airway opening assist device, which is applied to the anesthesia airway opening assist device of the above embodiment, and the method includes: Fixing the upper body of the user to the third fixing part, positioning the neck of the user on the second fixing part, and positioning the head of the user on the height adjustment device; The second fixing part fixes the user's neck to prevent the user's neck from deflecting to the left or right and causing injury during the process of opening the airway; The height adjustment device supports the user's head to prevent the user's head from tilting to the left or right during the airway opening process, thereby preventing injury; The plurality of first fixing parts are used to jointly abut and lift the user's jaw to open the airway; According to the specific situation of the user, the height of the user's head is adjusted by the height adjustment device so that the first contact surface is transformed from being parallel to the second contact surface to an angle formed by the first contact surface and the second contact surface being less than 180 degrees, thereby allowing the user's head to tilt back to further open the airway.

[0018] Anesthesia airway opening assist devices are a series of devices or tools used to help open and maintain the patient's airway during anesthesia.

[0019] In the related art, anesthesia airway opening assist devices usually open the airway by tilting the patient's head back, but this is not suitable for patients with neck injuries. Therefore, medical staff need to use the jaw support method to continuously open the airway of patients with neck injuries, which is very laborious.

[0020] Based on this, in order to improve the technical problem in the related art that it is laborious and occupies human resources for medical staff to continuously open the airway of patients with neck injuries during anesthesia, the embodiments of the present application provide the following solution.

[0021] Please also read Figure 1 and Figure 2 The embodiment of the present application provides an anesthesia airway opening assist device 100, the anesthesia airway opening assist device 100 comprises a first fixing portion 10, a second fixing portion 20 and a third fixing portion 30, wherein: The first fixing portion 10 includes a height adjustment device 11 and a plurality of first fixing devices 12. The first fixing devices 12 are arranged on the height adjustment device 11. The height adjustment device 11 is used to support the user's head and adjust the height of the user's head. The height adjustment device 11 has a first contact surface for contacting the user's head. The first fixing device 12 is used to support and move the user's lower jaw to open the airway.

[0022] The second fixing portion 20 is rotatably disposed on the height adjustment device 11 . The second fixing portion 20 is used to fix the neck of the user. The second fixing portion 20 has a second contact surface for contacting the neck of the user.

[0023] The third fixing part 30 is rotatably disposed on the second fixing part 20 for fixing to the upper body of the user. The second fixing part 20 may be located between the first fixing part 10 and the third fixing part 30 .

[0024] When the height adjustment device 11 lowers the height of the user's head, the height adjustment device 11 and the second fixing part 20 rotate relative to each other, so that the first contact surface is transformed from being parallel to the second contact surface to an angle between the first contact surface and the second contact surface being less than 180 degrees, thereby allowing the user's head to tilt back to open the airway.

[0025] It can be understood that the height adjustment device 11 is a device that can support the user's head and adjust the height of the user's head. For example, the height adjustment device 11 can be a cranial surgery head frame, a fixed head support, etc., but is not limited to this. The first fixing device 12 is a device that can support the user's mandible and drive the user's mandible away from the user's neck. It can be set on both sides of the height adjustment device 11 so that the user's head is located between at least two first fixing devices 12. For example, the first fixing device 12 can be a chin frame, a mandibular leading device, etc., but is not limited to this.

[0026] The second fixing part 20 is a device that can fix the user's neck and enable the user's head to tilt back with any position on the user's neck as the rotation center. For example, the second fixing part 20 may include a plurality of clamping components (neck fixer, inflatable neck brace, etc.) rotatably connected to each other, but is not limited thereto.

[0027] The third fixing part 30 is a device that can fix the upper body of the user thereto. For example, the third fixing part 30 can be a body position fixer, an upper limb fixer, etc., but is not limited thereto.

[0028] From the above, it can be seen that the anesthesia airway opening auxiliary device 100 provided in the embodiment of the present application is fixed to the upper body of the patient through the third fixing part 30 when in use, and the height of the height adjustment device 11 is adjusted so that the head of the patient in a lying state can be supported by the height adjustment device 11, and the neck can be supported by the second fixing part 20, and the neck of the patient is fixed by the second fixing part 20, and then the first fixing device 12 is used to support the patient's lower jaw and drive the patient's lower jaw away from the patient's neck, so that the position of the lower teeth is higher than the upper teeth, so that the patient's tongue root and epiglottis cartilage (a cartilage structure located behind the tongue root, used to close the larynx to prevent food from entering the airway) leave the front wall of the larynx, thereby ensuring that the airway is unobstructed, while avoiding the problem of medical staff needing to lift the patient's lower jaw and support the patient's neck for a long time, causing a waste of human resources. Furthermore, medical staff can adjust the height adjustment device 11 to lower the height of the patient's head according to the patient's on-site situation and the degree of airway opening, so that the height adjustment device 11 and the second fixing part 20 can rotate relative to each other and the angle formed between the first contact surface and the second contact surface is less than 180 degrees, so that the patient's head can be tilted back to further open the airway. Therefore, by adjusting the height adjustment device 11 as needed, the degree of the patient's head tilting back can be adjusted, thereby adjusting the degree of airway opening. In this process, since the second fixing part 20 supports and fixes the patient's neck, it can avoid moving the patient's body to cause secondary injury to the patient when further opening the airway. This is especially suitable for patients with neck injuries.

[0029] Optionally, the second fixing part 20 itself can be bent and deformed to facilitate adapting to the patient's neck shape, for example, a part of the second fixing part 20 can rotate relative to another part of the second fixing part 20. According to the patient's on-site situation and the degree of airway opening, the medical staff can operate the second fixing part 20 to make the height adjustment device 11 and part of the second fixing part 20 together as a first whole (with a first contact surface), and make the other part of the second fixing part 20 and the third fixing part 30 together as a second whole (with a second contact surface), and then adjust the height of the height adjustment device 11 so that the angle formed between the first contact surface and the second contact surface is less than 180 degrees, so that the patient's head is tilted back with the connection between the first whole and the second whole as the axis to open the airway, and then can adapt to the patient's neck, so as to avoid further opening the patient's airway while avoiding the patient's body from moving and causing secondary damage to the patient.

[0030] In some embodiments, please refer to Figure 1 and Figure 3 The height adjustment device 11 includes a first fixing plate 111 and an inflatable portion 112 .

[0031] The first fixing plate 111 is used to support the user's head, and the first fixing plate 111 has a first contact surface.

[0032] The inflatable portion 112 is disposed on a side of the first fixing plate 111 away from the first contact surface. The inflatable portion 112 is used to expand or contract to adjust the height of the first fixing plate 111 and further adjust the height of the user's head.

[0033] The first fixing device 12 is disposed on one side of the first fixing plate 111 close to the second fixing portion 20 , and the second fixing portion 20 is rotatably disposed on the first fixing plate 111 .

[0034] It can be understood that the first fixing plate 111 is a plate-like structure, for example, the first fixing plate 111 can be a rubber plate, a plastic plate, etc., but not limited thereto. The inflatable portion 112 is a device that can be inflated or deflated to expand or shrink, thereby driving the first fixing plate 111 to rise or fall, for example, the inflatable portion 112 can be an automatic inflation and deflation device, a pneumatic lifting platform, etc., but not limited thereto.

[0035] With such arrangement, the height of the first fixing plate 111 can be changed by inflating or deflating the inflatable portion 112, so that the first fixing plate 111 is fixed to the head of the user in a lying state; when the user's head tilts back when necessary, the height of the first fixing plate 111 can be lowered by deflating the inflatable portion 112, thereby driving the user's head to tilt back.

[0036] In some embodiments, please refer to Figure 1 and Figure 3 The first fixing part 10 also includes a plurality of second fixing devices 13, which are arranged on a side of the height adjustment device 11 away from the second fixing part 20, and at least two second fixing devices 13 are respectively arranged on both sides of the height adjustment device 11, and the second fixing devices 13 are used to approach and support the user's head to prevent the user's head from moving during anesthesia.

[0037] It can be understood that the second fixing device 13 is a device that can approach and abut the user's head, and can be respectively arranged on both sides of the first fixing plate 111 so that the user's head is located between at least two second fixing devices 13. For example, the second fixing device 13 may include a driving device (driving motor, driving cylinder, etc.) and a contact plate (rubber plate, flexible plate, etc.), but is not limited thereto; wherein the driving device is used to drive the contact plate to approach and abut the user's head, or drive the contact plate away from the user's head.

[0038] With such arrangement, when it is necessary to fix the patient's head to the height adjustment device 11, the patient's head is placed between at least two second fixing devices 13, and then each second fixing device 13 is brought close to and against the user's head, thereby fixing the user's head to the height adjustment device 11, thereby preventing the user's head from moving during the process of opening the airway.

[0039] In some embodiments, please refer to Figure 1 and Figure 3 The first fixing device 12 includes a first rotating member 121 and a fixing mechanism 122 .

[0040] The first rotating member 121 is rotatably disposed on a side of the height adjustment device 11 close to the second fixing portion 20 . A moving slot 1211 is defined on the first rotating member 121 .

[0041] The fixing mechanism 122 is movably disposed on the first rotating member 121 , and is used to abut and move the user's mandible to open the airway; wherein the fixing mechanism 122 can move closer to or farther from the height adjustment device 11 along the moving slot 1211 .

[0042] It can be understood that the first rotating member 121 is a mechanism that can be rotatably arranged on the height adjustment device 11. For example, the first rotating member 121 can be an aluminum plate, a plastic plate, etc., but is not limited thereto. The fixing mechanism 122 is a device that can support and move the user's mandible. For example, the fixing mechanism 122 can be a chin rest, a mandible leading device, etc., but is not limited thereto.

[0043] In this way, the fixing mechanism 122 is moved along the movable groove 1211 so that the fixing mechanism 122 is located beside the user's lower jaw, and then the fixing mechanism 122 approaches and abuts against the user's lower jaw to fix the user's lower jaw to the fixing mechanism 122, and then the fixing mechanism 122 is moved along the movable groove 1211 to move the fixing mechanism 122 away from the height adjustment device 11, thereby driving the user's lower jaw away from the height adjustment device 11, and then making the position of the lower teeth higher than the upper teeth to open the airway.

[0044] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 4 The fixing mechanism 122 includes a moving component 1221 and at least three fixing components 1222 .

[0045] The moving assembly 1221 is movably disposed on the first rotating member 121 and slidably fits in the moving groove 1211 .

[0046] At least three fixing components 1222 are rotatably disposed on the moving component 1221 , and the fixing components 1222 are used to support the user's lower jaw.

[0047] The moving component 1221 can drive at least three fixing components 1222 that are pressed against the user's lower jaw to move away from the height adjustment device 11 along the moving slot 1211 to make the user's lower teeth higher than the upper teeth, thereby opening the airway.

[0048] The moving component 1221 is a moving device that can move along the moving groove 1211. For example, the moving component 1221 may include a slider (plastic slider, aluminum slider, etc.) and a rotating locking member (rotating locking screw, rotating handle, etc.), but is not limited thereto; wherein the rotating locking member is rotatably arranged on the slider, and the rotating locking member is used to approach the slider and abut against the first rotating member 121, so that the first rotating member 121 simultaneously abuts against the slider and the rotating locking member. The fixing component 1222 is a device that can approach and abut against the user's lower jaw. For example, the fixing component 1222 may be a chin rest, a lower jaw leading device, etc., but is not limited thereto.

[0049] In this way, by moving the movable component 1221 along the movable groove 1211 to drive the fixed component 1222 to move, the fixed component 1222 is located beside the user's lower jaw, and then by driving the fixed component 1222 to approach and abut the user's lower jaw, at least one fixed component 1222 abuts against the lower jaw curve, at least one fixed component 1222 abuts against the lower jaw line, and at least one fixed component 1222 abuts against the chin tubercle, so that the user's lower jaw is fixed to at least three fixed components 1222, and the fixed components 1222 fixed to the user's lower jaw follow the movement of the movable component 1221 to drive the user's lower jaw to move together.

[0050] In some embodiments, see Figure 4 The moving component 1221 includes a positioning member 12211 and a first rotating member 12212 .

[0051] The positioning member 12211 is movably disposed on the first rotating member 121 . A rotating hole is formed on one side of the positioning member 12211 close to the first rotating member 121 . A thread is formed on the inner wall of the rotating hole.

[0052] The first rotating member 12212 is rotatably disposed on the positioning member 12211 and is partially located in the rotating hole; Among them, the fixing component 1222 is rotatably arranged on the positioning member 12211, and the first rotating member 121 is located between the positioning member 12211 and the first rotating member 12212. The first rotating member 12212 can rotate close to the positioning member 12211, so that the first rotating member 12212 and the positioning member 12211 simultaneously contact with the first rotating member 121, so that the positions of the positioning member 12211, the first rotating member 12212 and the fixing component 1222 and the first rotating member 121 are fixed. When the positioning member 12211 moves away from the first fixed plate 111 along the moving groove 1211, it can drive at least three fixing components 1222 that are against the user's lower jaw and move away from the height adjustment device 11 along the moving groove 1211 to make the user's lower teeth higher than the upper teeth, thereby opening the airway.

[0053] It can be understood that the positioning member 12211 is a cylindrical structure with a threaded hole, for example, the positioning member 12211 can be a threaded sleeve, a cylindrical pin with a threaded hole, etc., but not limited thereto. The first rotating member 12212 is a handle-shaped structure with a threaded column, for example, the first rotating member 12212 can be a star-shaped handle, an adjustment handle, etc., but not limited thereto.

[0054] In this way, when the position of the fixing assembly 1222 needs to be changed, the first rotating member 12212 is rotated to make the first rotating member 12212 away from the positioning member 12211, so that the first rotating member 121 located between the first rotating member 12212 and the positioning member 12211 is not interfered by the first rotating member 12212 and the positioning member 12211, and the first rotating member 12212 and the positioning member 12211 can move along the moving groove 1211 to drive the fixing assembly 1222 to move. movement; when it is necessary to fix the position of the fixing component 1222, the first rotating member 12212 is rotated to make the first rotating member 12212 close to the positioning member 12211, so that the first rotating member 121 located between the first rotating member 12212 and the positioning member 12211 is simultaneously resisted by the first rotating member 12212 and the positioning member 12211, thereby fixing the positions of the first rotating member 12212 and the positioning member 12211 with the first rotating member 121 to fix the fixing component 1222.

[0055] In some embodiments, please refer to Figure 3 and Figure 4 The fixing assembly 1222 includes a second rotating member 12221 and a supporting mechanism 12222 .

[0056] The second rotating member 12221 can be rotatably disposed on the moving assembly 1221 , and specifically can be rotatably disposed on the positioning member 12211 . A rack portion is disposed on one side of the second rotating member 12221 .

[0057] The supporting mechanism 12222 is movably disposed on the second rotating member 12221 and meshed with the rack portion. The supporting mechanism 12222 is used to support the user's lower jaw.

[0058] It can be understood that the second rotating member 12221 is a rod-shaped structure with teeth arranged along the length direction on one side. For example, the second rotating member 12221 can be a rack, a worm, etc., but is not limited thereto. The abutting mechanism 12222 is a device that can move along the second rotating member 12221 and approach the user's mandible to abut the user's mandible. For example, the abutting mechanism 12222 can be a mandible lifting device, a mandible supporter, etc., but is not limited thereto.

[0059] With such arrangement, when the user's lower jaw needs to be moved, the second rotating member 12221 is rotated and the supporting mechanism 12222 is moved along the length direction of the second rotating member 12221 so that the supporting mechanism 12222 is located beside the position on the user's lower jaw that needs to be supported, and then the supporting mechanism 12222 is brought close to and contacts the user's lower jaw to fix the lower jaw to the supporting mechanism 12222.

[0060] In some embodiments, please refer to Figure 4 and Figure 5 The supporting mechanism 12222 includes a moving shell 122221 , a moving wheel 122222 , a second rotating member 122223 and a supporting assembly 122224 .

[0061] The movable shell 122221 is movably disposed on the second rotating member 12221 . The movable shell 122221 has a movable accommodation space. Part of the second rotating member 12221 is located in the movable accommodation space. The side of the second rotating member 12221 away from the rack portion conflicts with the inner wall of the movable shell 122221 .

[0062] The moving wheel 122222 is located at one side of the moving accommodation space close to the rack portion, and is rotatably disposed on the moving shell 122221 , and the moving wheel 122222 is meshed with the rack portion.

[0063] The second rotating member 122223 is rotatably disposed on a side of the moving shell 122221 away from the height adjustment device 11 and is connected to the moving wheel 122222. The second rotating member 122223 is used to drive the moving wheel 122222 meshing with the rack portion to rotate, thereby driving the moving shell 122221 to approach or move away from the first rotating member 12212.

[0064] The supporting component 122224 is disposed on a side of the movable shell 122221 away from the second rotating member 122223 , and the supporting component 122224 is used for supporting the user's lower jaw.

The supporting component 122224 is a device that can approach and support the user's lower jaw, for example, the supporting component 122224 can be a lower jaw lifting device, a lower jaw supporter, etc., but is not limited thereto.

[0066] In this arrangement, when it is necessary to move the supporting component 122224, the moving wheel 122222 meshing with the rack portion on the second rotating component 12221 is driven to rotate by rotating the second rotating component 122223, thereby driving the moving shell 122221 to move along the second rotating component 12221, and further driving the supporting component 122224 to move to the side of the position on the user's lower jaw that needs to be supported.

[0067] In some embodiments, see Figure 4 The supporting assembly 122224 includes a supporting sleeve 1222241 , a third rotating member 1222242 , a supporting rod 1222243 and a supporting member 1222244 .

[0068] The supporting sleeve 1222241 is disposed on a side of the movable shell 122221 away from the second rotating member 122223 . The supporting sleeve 1222241 is provided with a supporting hole penetrating the supporting sleeve 1222241 in a direction perpendicular to the length direction of the second rotating member 12221 .

[0069] The third rotating member 1222242 is rotatably disposed on a side of the supporting sleeve 1222241 away from the height adjustment device 11 . A rotating hole is formed on the third rotating member 1222242 . The rotating hole is communicated with the supporting hole, and a thread is formed on the inner wall of the rotating hole.

[0070] The supporting rod 1222243 is movably disposed on the supporting sleeve 1222241 and is partially located in the rotating hole and the supporting hole. A thread that matches the thread on the inner wall of the rotating hole is formed on the outer wall of the supporting rod 1222243.

[0071] The supporting member 1222244 is rotatably disposed on one end of the supporting rod 1222243 away from the supporting sleeve 1222241 , and the supporting member 1222244 is used for supporting the lower jaw of the user.

[0072] It can be understood that the abutment sleeve 1222241 is a sleeve, for example, the abutment sleeve 1222241 can be a double groove threaded sleeve, a straight sleeve, etc., but not limited thereto. The third rotating member 1222242 is a sleeve with a threaded hole, for example, the third rotating member 1222242 can be a universal threaded sleeve, a straight threaded sleeve, etc., but not limited thereto. The abutment rod 1222243 is a rod-shaped structure with an external thread, for example, the abutment rod 1222243 can be a threaded rod, a threaded shaft, etc., but not limited thereto. The abutment member 1222244 is a rotating component with a plane on one side, for example, the abutment member 1222244 can include a rotating head (rotating joint, universal joint, etc.) and a contact member (rubber support, flexible plate, etc.), etc., but not limited thereto; wherein the contact member is arranged on the rotating head, and the rotating head is used to rotate to drive the contact member to rotate so that one side of the contact member fits with the user's lower jaw.

[0073] With such arrangement, when it is necessary to support the user's lower jaw, the supporting rod 1222243 engaged with the third rotating member 1222242 is driven close to the user's lower jaw by rotating the third rotating member 1222242, thereby driving the supporting member 1222244 close to the user's lower jaw and resisting against the user's lower jaw; when it is not necessary to support the user's lower jaw, the supporting rod 1222243 engaged with the third rotating member 1222242 is driven away from the user's lower jaw by rotating the third rotating member 1222242 in the other direction, thereby driving the supporting member 1222244 away from the user's lower jaw.

[0074] In some embodiments, please refer to Figure 2 and Figure 6 The first fixing plate 111 has first combination grooves 1111 on both sides, the third fixing portion 30 has third combination grooves 31 corresponding to the first combination grooves 1111 on both sides, and the second fixing portion 20 includes a plurality of third fixing devices 21 and two assemblies 22 .

[0075] At least one third fixing device 21 is rotatably disposed on the first fixing plate 111, at least one third fixing device 21 is rotatably disposed on the third fixing portion 30, each third fixing device 21 is rotatably connected to another adjacent third fixing device 21, the third fixing device 21 has a second contact surface, the third fixing device 21 is used to fix the user's neck, and second combination grooves 2111 are respectively provided on both sides of the third fixing device 21.

[0076] The two assemblies 22 are movably arranged on both sides of each third fixing device 21, and parts of the assembly 22 are located in the first combination groove 1111, the third combination groove 31 and the second combination groove 2111 on the same side. The assembly 22 is used to make the first fixing plate 111 and any number of third fixing devices 21 rotate together as a whole, and make the third fixing part 30 and other third fixing devices 21 as another whole.

[0077] It can be understood that the third fixing device 21 is a device that can fix the user's neck to prevent the user's neck from deflecting left and right. For example, the third fixing device 21 can be a neck brace, a neck fixer, etc., but is not limited thereto. The assembly 22 is a foldable curved rod. For example, the assembly 22 can be a foldable curved rod, a folding rod, etc., but is not limited thereto.

[0078] With such arrangement, when it is necessary to tilt the user's head back, the first fixing plate 111 and any number of third fixing devices 21 are made as a whole through the assembly 22. When the height of the first fixing plate 111 is lowered, the whole formed by the first fixing plate 111 and any number of third fixing devices 21 can rotate together with the gap between the third fixing device 21 farthest from the first fixing plate 111 in the whole and the third fixing device 21 closest to the first fixing plate 111 among the other third fixing devices 21 as the rotation axis to tilt the user's back, thereby avoiding moving the user's body to cause secondary injury to the user when it is necessary to tilt the user's head back to further open the airway.

[0079] In some embodiments, see Figure 6 The third fixing device 21 includes a second fixing plate 211 and two second fixing mechanisms 212 .

[0080] The second fixing plate 211 has a second contact surface with a fixing groove 2112 formed thereon. A rotation connection groove and a second combination groove 2111 are formed at both ends of the second fixing plate 211 . The second fixing plate 211 can be partially located in the rotation connection groove on the adjacent second fixing plate 211 .

[0081] The two second fixing mechanisms 212 are movably arranged on the second fixing plate 211 and are partially located in the fixing groove 2112. A neck accommodating space for accommodating the user's neck is formed between the two second fixing mechanisms 212. One of the second fixing mechanisms 212 can approach the other second fixing mechanism 212 along the fixing groove 2112 to fix the user's neck.

[0082] Among them, at least one second fixing plate 211 is rotatably disposed on the first fixing plate 111, at least one second fixing plate 211 is rotatably disposed on the third fixing portion 30, each second fixing plate 211 is rotatably connected to another adjacent second fixing plate 211, the second fixing plate 211 has a second contact surface, and the assembly 22 is used to make the first fixing plate 111 and any number of second fixing plates 211 rotate together as a whole, and make the third fixing portion 30 and another second fixing plate 211 as another whole.

[0083] It can be understood that the second fixing plate 211 is a plate-like structure with protrusions on both sides. For example, the second fixing plate 211 can be an aluminum plate, a plastic plate, etc., but not limited thereto. The second fixing mechanism 212 is a device that can move along the fixing groove 2112. For example, the second fixing mechanism 212 can be a translation clamping claw, a mobile clamper, etc., but not limited thereto.

[0084] With such arrangement, when the user's neck needs to be fixed, the user's neck is supported by the second fixing plate 211, and then the two second fixing mechanisms 212 are moved separately so that the two second fixing mechanisms 212 respectively contact the two sides of the user's neck to fix the user's neck, thereby preventing the user's neck from shifting left and right during the process of opening the airway.

[0085] In some embodiments, see Figure 7 A plurality of fixing holes are formed on the inner walls of both sides of the fixing groove 2112 , and the second fixing mechanism 212 includes a fixing member 2121 , two pressing members 2122 and a plurality of elastic members 2123 .

[0086] The fixing part 2121 is movably arranged on the second fixing plate 211 and is partially located in the fixing groove 2112. A fixed accommodating space is provided in the fixing part 2121. Pressing holes connected to the fixed accommodating space are respectively provided on both sides of the fixing part 2121 at one end away from the fixing groove 2112, and connecting holes connected to the fixed accommodating space are respectively provided on both sides of the fixing part 2121 at one end close to the fixing groove 2112. The connecting holes are located in the fixing groove 2112 and correspond to the positions of the fixing holes. One of the fixing parts 2121 can approach the other fixing part 2121 along the fixing groove 2112 to fix the user's neck.

[0087] The two pressing pieces 2122 are respectively partially located on both sides of the fixed accommodating space, and are movably arranged on the fixing piece 2121, and respectively correspond to the positions of the pressing hole and the connecting hole. The pressing piece 2122 is partially located outside the fixed accommodating space through the pressing hole, and the pressing piece 2122 can be partially located inside the fixing hole through the connecting hole.

[0088] A plurality of elastic members 2123 are located in the fixed accommodation space, and two ends of the elastic members 2123 are respectively connected to the two pressing members 2122 . The elastic members 2123 are used to drive the two pressing members 2122 to move away from each other.

[0089] It can be understood that the fixing member 2121 is a rectangular parallelepiped structure with a wedge-shaped end. For example, the material of the fixing member 2121 can be aluminum, plastic, etc., but not limited thereto. The pressing member 2122 is a "concave" structure. For example, the material of the pressing member 2122 can be aluminum, plastic, etc., but not limited thereto. The elastic member 2123 is a spring. For example, the elastic member 2123 can be a coil spring, a disc spring, etc., but not limited thereto.

[0090] With such arrangement, when it is necessary to move the fixing member 2121 to fix the user's neck, the parts of the two pressing members 2122 outside the pressing hole are continuously pressed at the same time, so that the parts of the two pressing members 2122 inside the fixing hole are completely moved into the fixed accommodating space, and then the fixing member 2121 is moved along the fixing groove 2112 so that the fixing member 2121 contacts the user's neck, and then the parts of the two pressing members 2122 outside the pressing hole are released. The two pressing members 2122 move away from each other under the elastic force of the elastic member 2123, and are respectively located in the fixing hole through the connecting hole parts, so as to fix the pressing member 2122 to the second fixing plate 211, and further fix the fixing member 2121 to the second fixing plate 211.

[0091] In some embodiments, see Figure 2 and Figure 6 The assembly 22 includes a first bending rod 221 and a second bending rod 222 .

[0092] Among them, one end of the first bending rod 221 is rotatably connected to one end of the second bending rod 222, and the first bending rod 221 can be rotated in the direction of the user's leaning back to approach the second bending rod 222. The other end of the first bending rod 221 is opposite to and spaced from the other end of the second bending rod 222. The first bending rod 221 is partially located in the first combination groove 1111 and the second combination groove 2111, and the second bending rod 222 is partially located in the third combination groove 31 and the second combination groove 2111. The distance between the other end of the first bending rod 221 and the other end of the second bending rod 222 is less than the length of the second fixed plate 211 and greater than the gap between two adjacent second fixed plates 211. The first bending rod 221 is used to make the first fixed plate 111 and any number of second fixed plates 211 rotate together as a whole, and the second bending rod 222 is used to make the third fixing portion 30 and other second fixed plates 211 as a whole.

[0093] It can be understood that the first bending rod 221 and the second bending rod 222 are a kind of "C"-shaped bending rods. For example, the first bending rod 221 may include a first rotating rod, a first connecting rod and a first combined rod, and the second bending rod 222 may include a second rotating rod, a second connecting rod and a second combined rod, wherein the first rotating rod and the second rotating rod are located outside the first combined groove 1111, the second combined groove 2111 and the third combined groove 31, the first connecting rod is partially located in the first combined groove 1111, the second connecting rod is partially located in the third combined groove 31, the first combined rod is located in the first combined groove 1111 and the second combined groove 2111, the second combined rod is located in the third combined groove 31 and the second combined groove 2111, and one end of the first rotating rod is connected to the second rotating rod. One end of the first rotating rod is rotatably connected, the other end of the first rotating rod is connected to one end of the first connecting rod, the other end of the first connecting rod is connected to one end of the first combination rod, the first rotating rod and the first combination rod are parallel to each other and are in the same plane, the other end of the second rotating rod is connected to one end of the second connecting rod, the other end of the second connecting rod is connected to one end of the second combination rod, the second rotating rod and the second combination rod are parallel to each other and are in the same plane, a straight-line distance between the other end of the first combination rod and the other end of the second combination rod is less than the length of the second combination groove 2111 and greater than the gap between two adjacent second fixing plates 211, and a connection between the first rotating rod and the second rotating rod corresponds to the gap between the other end of the first combination rod and the other end of the second combination rod.

[0094] In this way, when the user's head needs to be tilted back, the first bending rod 221 is moved so that the connection between the first bending rod 221 and the second bending rod 222 is located between the gaps between the two second fixing plates 211 adjacent to the position where the user's neck needs to be rotated, so that the first bending rod 221, the first fixing plate 111 and part of the second fixing plate 211 together form a whole having a first contact surface, and the second bending rod 222, the third fixing portion 30 and the other second fixing plates 211 together form another whole having a second contact surface, so that the user's head can be tilted back between the two wholes. The connection is a rotating axis that rotates so that the angle between the first contact surface and the second contact surface is less than 180 degrees, thereby allowing the user's head to tilt back; when the user's head does not need to be tilted back, the other end of the first bending rod 221 (the end not connected to the second bending rod 222) and the other end of the second bending rod 222 (the end not connected to the first bending rod 221) are moved to the second combination groove 2111 of the same second fixed plate 211, so that the first fixed plate 111, all the second fixed plates 211 and the third fixed portion 30 are together as a whole (the first contact surface is parallel to the second contact surface).

[0095] Exemplarily, it is assumed that four second fixing plates 211 are evenly arranged between the first fixing plate 111 and the third fixing portion 30, and the four second fixing plates 211 are numbered 1, 2, 3, and 4, starting from the second fixing plate 211 closest to the first fixing plate 111. When it is necessary to rotate the user's neck with the gap between the second fixing plates 211 numbered 2 and 3 as the axis to make the user's head tilt back, the first bending rod 221 is moved so that the other end of the first bending rod 221 is located in the second combination groove 2111 of the second fixing plate 211 numbered 2, so that the first fixing plate 111, the second fixing plate 211 numbered 1, and the second fixing plate 211 numbered 2 are rotated together as a whole, and the second bending rod 222 is moved so that the other end of the second bending rod 222 is located in the second combination groove 2111 of the second fixing plate 211 numbered 3, so that the second fixing plate 211 numbered 3, the second fixing plate 211 numbered 4, and the third fixing portion 30 are another whole; When only the first fixed plate 111 needs to be rotated, move the second bending rod 222 so that the other end of the second bending rod 222 is located in the second combination groove 2111 of the second fixed plate 211 numbered 1, so that the four second fixed plates 211 numbered 1, 2, 3, 4 and the third fixing part 30 are as a whole, move the first bending rod 221 so that the other end of the first bending rod 221 is located in the first combination groove 1111, so that the first fixed plate 111 alone is another whole.

[0096] The present application also provides an anesthesia airway opening assist device control method, which is applied to the anesthesia airway opening assist device of any of the above embodiments. The anesthesia airway opening assist device control method includes: The upper body of the user is fixed to the third fixing part 30 , the neck of the user is placed on the second fixing part 20 , and the head of the user is placed on the height adjustment device 11 .

[0097] The second fixing part 20 fixes the user's neck to prevent the user's neck from deflecting to the left or right and causing injury during the process of opening the airway.

[0098] The height adjustment device 11 supports the user's head to prevent the user's head from tilting to the left or right and causing injury during the process of opening the airway.

[0099] The plurality of first fixing parts 10 are used to jointly support and lift the user's jaw to open the airway.

[0100] According to the specific situation of the user, the height of the user's head is adjusted by the height adjustment device 11 so that the first contact surface is transformed from being parallel to the second contact surface to the angle formed between the first contact surface and the second contact surface being less than 180 degrees, thereby allowing the user's head to tilt back to further open the airway.

[0101] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
