Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0024] The present application will be described in detail below with reference to the accompanying drawings and specific implementation manners.

[0025] Embodiment

[0026] As Figures 1 - 6 shown, a tracheal intubation fixation structure includes: a fixing plate 1, an opening groove 101 opened in the middle of the fixing plate 1, connecting heads 2 installed on both outer ends of the fixing plate 1, a fixing component arranged inside the opening groove 101, the fixing component includes: a left fixing clamp 102, a right fixing clamp 103, a movable rod 104, an L-shaped pulling block 105, a limiting groove 106, a through hole 107, a pressing block 108 and a spring 109, a locking component arranged outside the opening groove 101, the locking component includes: a locking screw hole 3, a locking screw 301 and a fixing screw hole 4.

[0027] Among them, a left fixing clip 102 is provided on one side inside the opening groove 101. A right fixing clip 103 is provided on one side of the left fixing clip 102. Moving rods 104 are installed at the outer ends of the right fixing clip 103 and the left fixing clip 102. L-shaped pulling blocks 105 are fixedly installed on the outer sides of the moving rods 104 through bolts. Limit grooves 106 are provided at both ends of the opening groove 101. Through holes 107 are opened between the limit grooves 106 and the opening groove 101. A pressing block 108 is provided inside the limit groove 106. A spring 109 is installed between the pressing block 108 and the limit groove 106. And the moving rod 104 passes through the through hole 107 and is fixedly connected to the pressing block 108.

[0028] When inserting the tracheal intubation into the patient's oral cavity, ask the patient to cooperate to open the mouth, and insert the tracheal intubation through the opening groove 101 in the middle of the fixing plate 1, that is, insert one end of the opening groove 101 into the patient's oral cavity and insert it into the trachea. When the tracheal intubation passes through the opening groove 101 in the middle of the fixing plate 1, hold the L-shaped pulling block 105 with your hand and pull the moving rod 104 to both sides. The moving rod 104 is stressed and passes through the through hole 107 and moves into the limit groove 106. The moving rod 104 squeezes the pressing block 108 and the spring 109. At this time, the moving rod 104 drives the left fixing clip 102 and the right fixing clip 103 to move relative to each other and pull apart. After the tracheal intubation is inserted into the trachea, release the L-shaped pulling block 105. At this time, the moving rod 104 is not subjected to the pulling force, and does not exert force on the pressing block 108 and the spring 109. The spring 109 restores its deformation, pushes the pressing block 108 and the moving rod 104 back to their original positions, so that the left fixing clip 102 and the right fixing clip 103 move closer to each other to clamp and fix the tracheal intubation, fix the tracheal intubation inside the opening groove 101, solve the problem that the traditional method of tying the tracheal intubation with a rope is prone to looseness, clamp and fix the tracheal intubation, and ensure the stable use of the tracheal intubation.

[0029] Among them, an elastic band a5 is installed at the outer end of the connector 2. A magic tape a501 is sewn on the front of the elastic band a5. The magic tape a501 is a burr surface. An elastic band b6 is installed at the outer end of the connector 2. A magic tape b601 is sewn on the back of the elastic band b6. The magic tape b601 is a velveteen surface.

[0030] After fixing the tracheal intubation in the fixing plate 1, place the fixing plate 1 against the outside of the patient's mouth, and then stretch and wind the elastic band a5 and the elastic band b6 at the outer end of the connector 2 around the patient's head, so that the magic tape a501 on the front of the elastic band a5 and the magic tape b601 on the back of the elastic band b6 are pasted and fixed together, and then install the fixing plate 1 on the patient's mouth for use.

[0031] Among them, the middle part of the top end of the fixing plate 1 is in a "V" shape. When the fixing plate 1 is installed on the patient's mouth, the top part of the fixing plate 1 is close to the patient's nose. The middle part of the top end of the fixing plate 1 is arranged in a "V" shape, so that it will not block the air outlet or air intake of the nostrils.

[0032] Among them, sliders 112 are installed at the top and bottom of the left fixing clamp block 102 and the right fixing clamp block 103. Sliding grooves 113 which are slidably connected with the sliders 112 are arranged at the top end and the bottom end inside the opening groove 101. When the movable rod 104 drives the left fixing clamp block 102 and the right fixing clamp block 103 to move back and forth, the sliders 112 and the sliding grooves 113 can support the left fixing clamp block 102 and the right fixing clamp block 103, so that the left fixing clamp block 102 and the right fixing clamp block 103 are stably placed inside the opening groove 101. Moreover, the left fixing clamp block 102 and the right fixing clamp block 103 are slidably connected with the sliding grooves 113 at the top end and the bottom end inside the opening groove 101 through the sliders 112, which can also prevent the left fixing clamp block 102 and the right fixing clamp block 103 from being worn and damaged with the opening groove 101, and is helpful for pulling and adjusting the positions between the left fixing clamp block 102 and the right fixing clamp block 103 for use.

[0033] Among them, inner embedding grooves 110 are arranged on the outer sides of the left fixing clamp block 102 and the right fixing clamp block 103, and magnets 111 are fixedly installed inside the inner embedding grooves 110. When the left fixing clamp block 102 and the right fixing clamp block 103 move close to each other to clamp and fix the tracheal intubation, the left fixing clamp block 102 and the right fixing clamp block 103 will fit together. At this time, the magnets 111 inside the inner embedding grooves 110 will be magnetically attracted and fixed together, increasing the stability between the left fixing clamp block 102 and the right fixing clamp block 103 and preventing the tracheal intubation from loosening between the left fixing clamp block 102 and the right fixing clamp block 103.

[0034] Since inner embedding grooves 110 and magnets 111 are arranged on the outer sides of the left fixing clamp block 102 and the right fixing clamp block 103, and the magnets 111 on the left fixing clamp block 102 and the right fixing clamp block 103 are a group of opposite-sex magnets, the magnets 111 can attract each other and be magnetically fixed together.

[0035] Among them, a locking screw hole 3 is provided on the outer side of the opening groove 101. A locking screw rod 301 is threadedly connected inside the locking screw hole 3. A fixing screw hole 4 is provided at the relative position between the outer side of the movable rod 104 and the locking screw hole 3. When the spring 109 restores its deformation and pushes the pressing block 108 and the movable rod 104 back to their original positions, the fixing screw hole 4 on the outer side of the movable rod 104 just aligns with the locking screw hole 3 on the outer side of the opening groove 101. After the left fixing clamp 102 and the right fixing clamp 103 clamp and fix the tracheal intubation, the locking screw rod 301 is screwed into the locking screw hole 3 and penetrates into the fixing screw hole 4. The locking screw rod 301 is continuously rotated and tightened inside the locking screw hole 3 and the fixing screw hole 4 to lock and fix the movable rod 104 and the opening groove 101, preventing the tracheal intubation from being pulled and causing the left fixing clamp 102 and the right fixing clamp 103 to push the movable rod 104 to move, and preventing the tracheal intubation from loosening.

[0036] When the tracheal intubation needs to be disassembled, first rotate and loosen the locking screw rod 301 and take it out from inside the locking screw hole 3 and the fixing screw hole 4 to release the fixation between the movable rod 104 and the opening groove 101, so that the movable rod 104 can move inside the through hole 107. At this time, hold the L-shaped pull block 105 with the hand and pull the movable rod 104 to both sides. The movable rod 104 is stressed and penetrates into the limiting groove 106 through the through hole 107. The movable rod 104 squeezes the pressing block 108 and the spring 109. The movable rod 104 drives the left fixing clamp 102 and the right fixing clamp 103 to move relative to each other and widen the distance, and then the tracheal intubation can be pulled out from the patient's oral cavity.

[0037] Working principle:

[0038] When inserting the tracheal intubation into the patient's oral cavity, ask the patient to cooperate to open the mouth, and insert the tracheal intubation through the opening groove 101 in the middle of the fixing plate 1, that is, insert one end through the opening groove 101 into the patient's oral cavity and then into the trachea. When the tracheal intubation passes through the opening groove 101 in the middle of the fixing plate 1, hold the L-shaped pull block 105 with the hand and pull the movable rod 104 to both sides. The movable rod 104 is stressed and penetrates into the limiting groove 106 through the through hole 107. The movable rod 104 squeezes the pressing block 108 and the spring 109. At this time, the movable rod 104 drives the left fixing clamp 102 and the right fixing clamp 103 to move relative to each other and widen the distance. After the tracheal intubation is inserted into the trachea, release the L-shaped pull block 105. At this time, the movable rod 104 is not subjected to tensile force and does not apply force to the pressing block 108 and the spring 109. The spring 109 restores its deformation and pushes the pressing block 108 and the movable rod 104 back to their original positions, so that the left fixing clamp 102 and the right fixing clamp 103 move closer to each other to clamp and fix the tracheal intubation, fixing the tracheal intubation inside the opening groove 101, solving the problem that the traditional method of tying the tracheal intubation with a rope is prone to loosening, clamping and fixing the tracheal intubation, and ensuring the stable use of the tracheal intubation.

[0039] Then, stretch the elastic band a5 and the elastic band b6 at the outer end of the connector 2 and wind them around the patient's head, so that the magic tape a501 on the front of the elastic band a5 is adhered and fixed to the magic tape b601 on the back of the elastic band b6. Then, install the fixing plate 1 on the patient's mouth for use. When the pressing block 108 and the movable rod 104 return to their original positions, the fixing screw hole 4 on the outer side of the movable rod 104 is just aligned with the locking screw hole 3 on the outer side of the opening groove 101. After the left fixing clamp block 102 and the right fixing clamp block 103 clamp and fix the tracheal intubation, screw the locking screw rod 301 into the locking screw hole 3 and penetrate it into the fixing screw hole 4. Continuously rotate and tighten the locking screw rod 301 in the locking screw hole 3 and the fixing screw hole 4 to lock and fix the movable rod 104 to the opening groove 101, so as to prevent the tracheal intubation from being pulled and causing the left fixing clamp block 102 and the right fixing clamp block 103 to push the movable rod 104 to move, and prevent the tracheal intubation from becoming loose.
