Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to an anesthesia intubation assistance device. Background Technology

[0002] In related technologies, when anesthetizing patients in clinical practice, it is usually necessary to intubate the patient first. Intubation refers to the technique of inserting a specially designed endotracheal tube into the trachea through the glottis. During patient anesthesia, the doctor needs to hold the intubation tube and keep the position and angle of the intubation tube unchanged before performing the anesthesia procedure.

[0003] Among the existing technologies (patent application No. CN109044710A, patent name: A Clinical Anesthesia Intubation Assist Device for Anesthesiology Department), the present invention has a novel concept and ingenious structure, which can conveniently fix and adjust the head of patients in bronchoscopy, thereby improving the efficiency and quality of the surgery.

[0004] In the process of implementing this technical solution, it was found that the existing technology has at least the following problems: the existing anesthesia intubation auxiliary devices use methods such as pillows to support the shoulders and head rings to restrict the patient's head, which can easily cause the patient's head to shift during the operation. Slight changes in the patient's position can lead to surgical errors or even serious medical accidents. At the same time, the patient's mouth is not easy to open after the head is fixed, which affects the operation of medical staff and increases the difficulty of intubation. Summary of the Invention

[0005] This application aims to at least solve one of the technical problems existing in the prior art where the patient's mouth is difficult to open after the head is fixed. To this end, this application proposes an anesthesia intubation assistance device.

[0010] According to some embodiments of this application, the side wall of the clamping box is provided with a pressing mechanism. The pressing mechanism includes a movable box fixedly connected to the side wall of the clamping box. The side wall of the movable box is provided with a longitudinal movement groove. The inner wall of the movable box is slidably connected with a lifting block. The side wall of the lifting block is fixedly connected with a sliding column. The outer wall of the sliding column is slidably connected to the inner wall of the longitudinal movement groove.

[0011] According to some embodiments of this application, the outer wall of the sliding column is slidably connected to an inclined groove plate, and the side wall of the inclined groove plate is fixedly connected to an L-shaped fixing frame, the side wall of the L-shaped fixing frame being fixedly connected to the side wall of the support plate.

[0012] According to some embodiments of this application, a lifting limit frame is fixedly connected to the top of the support plate, a lifting groove is provided on the side wall of the lifting limit frame, a limit guide post is slidably connected to the inner wall of the lifting groove, the limit guide post passes through the side wall of the lifting block and extends to the outside, and the inner wall of the lifting block is slidably connected to the outer wall of the limit guide post.

[0013] According to some embodiments of this application, a connecting box is fixedly connected to the end of the limiting guide post away from the lifting limiting frame. A limiting slide rod is fixedly connected to the inner wall of the connecting box. An arc-shaped pressing hose is slidably connected to the outer wall of the limiting slide rod. A connecting spring is fixedly connected to the outer wall of the arc-shaped pressing hose. The end of the connecting spring away from the arc-shaped pressing hose is fixedly connected to the inner wall of the connecting box.

[0014] According to some embodiments of this application, the side wall of the lifting limit frame is provided with a throat mechanism. The throat mechanism includes a horizontal groove plate fixedly connected to the side wall of the lifting limit frame. A rotating rod is slidably connected to the inner wall of the horizontal groove plate, and a gear is fixedly connected to the outer wall of the rotating rod.

[0015] According to some embodiments of this application, a guide frame is fixedly connected to the outer wall of the limiting guide post, a guide groove is provided on the side wall of the guide frame, the inner wall of the guide groove is slidably connected to the outer wall of the rotating rod, an L-shaped support plate is fixedly connected to the side wall of the guide frame, and a toothed plate is fixedly connected to the side wall of the L-shaped support plate.

[0016] According to some embodiments of this application, the outer wall of the rotating rod is provided with a throat assembly, the throat assembly includes a pressure handle fixedly connected to the outer wall of the rotating rod, a pressure tongue fixedly connected to the side wall of the pressure handle, a miniature camera fixedly connected to the side wall of the pressure tongue, a light fixedly connected to the side wall of the pressure tongue, and a display fixedly connected to the side wall of the pressure handle.

[0017] The beneficial effects of this application are:

[0018] 1. This anesthesia intubation assistance device allows the patient to place their head on a soft pad. Medical staff can rotate the handle, which in turn rotates a spiral rod. This spiral rod causes a sliding block to move within the clamping groove. The sliding block, in turn, moves the clamping frame and the sponge clamping pillow to hold and fix the patient's head in place. This prevents the catheter from dislodging or bending due to head movement during surgery. A forehead limiting plate prevents the patient's head from slipping off during clamping, thus improving the efficiency and quality of the surgery.

[0019] 2. In this anesthesia intubation assistance device, during the clamping of the patient's head, the moving slider drives the L-shaped compression rod to be inserted into the gas box. The L-shaped compression rod pushes the compression plate to move, and the compression plate compresses the gas inside the gas box. Because the through hole is connected to the transmission chamber, the compressed gas is transported to the transmission chamber through the through hole and then to the clamping box through the connecting pipe, thereby inflating the inflatable balloon. After the inflatable balloon expands, it compresses the front of the patient's cheek, opening the patient's mouth, which makes it easier for medical staff to accurately insert the catheter into the patient's mouth.

[0020] 3. In this anesthesia intubation assistance device, when the clamping box moves towards the patient's face, the clamping box moves the moving box, which in turn moves the lifting block. The lifting block, guided by a sliding column on an inclined plate, descends as it moves laterally. The lifting block then moves the limiting guide column downwards, which in turn moves the connecting box and the limiting slide rod downwards. The limiting slide rod then moves the arc-shaped compression hose to compress the patient's jaw. The arc-shaped compression hose can be moved by a connecting spring to allow the patient's jaw to move further, facilitating a wider mouth opening and preventing injury to the patient during intubation. This improves the efficiency of intubation for medical staff and ensures the catheter is smoothly inserted into the trachea.

[0021] 4. In this anesthesia intubation assistance device, the moving box compresses the inclined surface of the trapezoidal block, causing the trapezoidal block to descend. Because the limiting frame laterally limits the transverse sliding rod, after the trapezoidal block descends, the transverse sliding rod is located at the top of the inclined groove. The transverse sliding rod pushes the push plate to move, and the push plate pushes the neck-lifting pad to rise through the connecting shaft. The neck-lifting pad raises the patient's neck, and the forehead limiting plate restricts the patient's forehead, causing the patient's head to tilt backward, so that the patient's mouth, pharynx, and larynx are in a straight line, so that the patient's airway is opened, so as to fully expose the trachea and facilitate the insertion of the tube.

[0022] 5. In this anesthesia intubation auxiliary device, when the limiting guide column descends, the limiting guide column pulls the guide frame downward. When the rotating rod slides in the straight groove of the guide groove, the rotating rod drives the gear to contact the toothed plate. The gear drives the rotating rod to rotate, and the rotating rod drives the pressure handle to rotate. The pressure handle drives the tongue depressor to be inserted into the patient's mouth. When the rotating rod moves to the inclined groove of the guide groove, the gear disengages from the toothed plate, and the rotating rod moves to the top of the guide groove. The rotating rod drives the pressure handle and the tongue depressor to press down on the patient's tongue root, thereby exposing the patient's pharynx. The illumination lamp illuminates the patient's epiglottis and glottis, and the miniature camera transmits the image to the monitor for easy observation by medical staff, facilitating intubation operations.

[0048] like Figure 1 - Figure 13 As shown in the embodiment of this application, an anesthesia intubation auxiliary device includes a fixed plate 101. A support plate 102 is fixedly connected to the top of the fixed plate 101. A clamping groove 103 is formed on the top of the support plate 102. A movable slider 104 is slidably connected to the inner wall of the clamping groove 103. A helical rod 105 is rotatably connected to the side wall of the movable slider 104. This configuration allows the helical rod 105 to drive the movable slider 104 to slide within the clamping groove 103. A rotating handle 106 is fixedly connected to one end of the helical rod 105, which facilitates medical personnel to rotate the rotating handle 106 to move the slider. A clamping frame 107 is fixedly connected to the top of the support plate 104. A sponge clamping pillow 108 is fixedly connected to the side wall of the clamping frame 107. The sponge clamping pillow 108 is used to clamp and fix the patient's head, preventing the catheter from falling off or bending due to head movement during the operation. A forehead limiting plate 109 is fixedly connected to the top of the sponge clamping pillow 108. The forehead limiting plate 109 prevents the patient's head from falling off during clamping, improving the efficiency and quality of the operation. A soft pad 11 is fixedly connected to the top of the support plate 102. This design facilitates protection of the patient's head. It also includes:

[0049] The expansion and compression mechanism 2 includes an L-shaped compression rod 201 fixedly connected to the side wall of the movable slider 104. The L-shaped compression rod 201 has a transmission cavity 202 inside. A connecting pipe 203 is provided on the side wall of the L-shaped compression rod 201, and the interior of the connecting pipe 203 communicates with the interior of the transmission cavity 202. A clamping box 204 is fixedly connected to the outer wall of the connecting pipe 203. The side wall of the clamping box 204 is fixedly connected to the side wall of the clamping frame 107. An expansion airbag 205 is fixedly connected to the side wall of the clamping box 204. This arrangement is for the expansion airbag 205 to compress the front of the patient's cheek after inflation, thereby opening the patient's mouth. The top of the support plate 102 is fixedly connected to... A gas box 206 is connected, and the side wall of the L-shaped extrusion rod 201 penetrates the side wall of the gas box 206 and extends to the inside. This is designed so that the L-shaped extrusion rod 201 can be inserted into the gas box 206. Two extrusion plates 207 are slidably connected to the inner wall of the gas box 206. The side wall of the extrusion plate 207 has a through hole 208, and the inner wall of the through hole 208 is connected to the inner wall of the transmission cavity 202. This is designed so that the extrusion plate 207 can extrude gas into the gas box 206. Since the through hole 208 is connected to the transmission cavity 202, the extruded gas is transported into the transmission cavity 202 through the through hole 208. A return spring 209 is fixedly connected between the two extrusion plates 207 to facilitate the return of the extrusion plates 207.

[0050] The clamping box 204 has a pressing mechanism 3 on its side wall. The pressing mechanism 3 includes a movable box 301 fixedly connected to the side wall of the clamping box 204. The side wall of the movable box 301 has a longitudinal movement groove 302. A lifting block 303 is slidably connected to the inner wall of the movable box 301. A sliding column 304 is fixedly connected to the side wall of the lifting block 303. The outer wall of the sliding column 304 is slidably connected to the inner wall of the longitudinal movement groove 302. An inclined groove plate 305 is slidably connected to the outer wall of the sliding column 304. An L-shaped fixing frame 306 is fixedly connected to the side wall of the inclined groove plate 305. The side wall of the L-shaped fixing frame 306 is fixedly connected to the side wall of the support plate 102. A lifting limit frame is fixedly connected to the top of the support plate 102. 307. The side wall of the lifting and limiting frame 307 is provided with a lifting groove 308. The inner wall of the lifting groove 308 is slidably connected to a limiting guide post 309. The limiting guide post 309 passes through the side wall of the lifting block 303 and extends to the outside. The inner wall of the lifting block 303 is slidably connected to the outer wall of the limiting guide post 309. This is designed so that when the clamping box 204 moves toward the patient's face, the clamping box 204 drives the moving box 301 to move. The moving box 301 drives the lifting block 303 to move. The lifting block 303 is guided by the sliding column 304 on the inclined plate 305 and descends when the lifting block 303 moves laterally. The lifting block 303 drives the limiting guide post 309 to descend.

[0051] A connecting box 31 is fixedly connected to the end of the limiting guide post 309 away from the lifting limiting frame 307. A limiting slide rod 32 is fixedly connected to the inner wall of the connecting box 31. An arc-shaped compression hose 33 is slidably connected to the outer wall of the limiting slide rod 32. A connecting spring 34 is fixedly connected to the outer wall of the arc-shaped compression hose 33. The end of the connecting spring 34 away from the arc-shaped compression hose 33 is fixedly connected to the inner wall of the connecting box 31. This arrangement is for the limiting guide post 309 to drive the connecting box 31 and the limiting slide rod 32 to descend. The limiting slide rod 32 drives the arc-shaped compression hose 33 to squeeze the patient's jaw. The arc-shaped compression hose 33 can be moved by the movement of the patient's jaw through the connecting spring 34, which makes it easier for the patient to open their mouth wider, avoids injury to the patient during intubation, improves the efficiency of medical staff in intubation, and allows the tube to be smoothly inserted into the trachea.

[0052] The side wall of the lifting limit frame 307 is provided with a throat mechanism 5. The throat mechanism 5 includes a horizontal slot plate 501 fixedly connected to the side wall of the lifting limit frame 307. A rotating rod 502 is slidably connected to the inner wall of the horizontal slot plate 501. A gear 503 is fixedly connected to the outer wall of the rotating rod 502. A guide frame 504 is fixedly connected to the outer wall of the limiting guide post 309. A guide groove 505 is opened on the side wall of the guide frame 504. The inner wall of the guide groove 505 is slidably connected to the outer wall of the rotating rod 502. An L-shaped support plate 506 is fixedly connected to the side wall of the guide frame 504. A toothed plate 507 is fixedly connected to the side wall of the L-shaped support plate 506. This arrangement is for limiting the movement. The guide post 309 pulls the guide frame 504 to descend. When the rotating rod 502 slides in the straight groove of the guide groove 505, the rotating rod 502 drives the gear 503 to contact the toothed plate 507. The gear 503 drives the rotating rod 502 to rotate, and the rotating rod 502 drives the pressure handle 601 to rotate. The pressure handle 601 drives the tongue depressor 602 to be inserted into the patient's mouth. When the rotating rod 502 moves to the inclined groove of the guide groove 505, the gear 503 disengages from the toothed plate 507, and the rotating rod 502 moves to the top of the guide groove 505. The rotating rod 502 drives the pressure handle 601 and the tongue depressor 602 to press down on the root of the patient's tongue, thereby exposing the patient's throat.

[0053] The outer wall of the rotating rod 502 is provided with a laryngeal intubation assembly 6. The laryngeal intubation assembly 6 includes a pressure handle 601 fixedly connected to the outer wall of the rotating rod 502. A tongue depressor 602 is fixedly connected to the side wall of the pressure handle 601. This is designed so that the tongue depressor 602 can restrict the root of the patient's tongue. A miniature camera 603 is fixedly connected to the side wall of the tongue depressor 602. A light 604 is fixedly connected to the side wall of the tongue depressor 602. The light 604 is set to illuminate the patient's epiglottis and glottis. A display 605 is fixedly connected to the side wall of the pressure handle 601. The miniature camera 603 transmits the image to the display 605 for observation by medical staff.

[0054] like Figure 8 and Figure 9As shown, because the endotracheal tube is relatively hard while the tracheal mucosa is relatively delicate, forcibly inserting it before the airway is open can cause tracheal damage. If the tube cannot be inserted in time, it can lead to prolonged hypoxia, suffocation, and other complications. Insertion without exposing the trachea can cause the tube to fold or twist, increasing patient suffering, workload for medical staff, and medical costs. The inner wall of the support plate 102 is provided with a neck-lifting mechanism 4, which includes a trapezoidal block 401 slidably connected to the inner wall of the support plate 102. The side wall of the trapezoidal block 401 has an inclined groove 402. The inner wall of the inclined groove 402 is slidably connected to a transverse sliding rod 403. The outer wall of the transverse sliding rod 403 is slidably connected to a limit frame 404. The side wall of the limit frame 404 is fixedly connected to the bottom of the support plate 102. The outer wall of the transverse sliding rod 403 is rotatably connected to a push plate. 405. The end of the push plate 405 away from the transverse sliding rod 403 is rotatably connected to the connecting shaft 406. The outer wall of the connecting shaft 406 is fixedly connected to the neck lifting pad 407. The moving box 301 squeezes the inclined surface of the trapezoidal block 401, causing the trapezoidal block 401 to descend. Because the limiting frame 404 laterally limits the transverse sliding rod 403, after the trapezoidal block 401 descends, the transverse sliding rod 403 is located at the top of the inclined groove 402. The transverse sliding rod 403 pushes the push plate 405 to move. The push plate 405 pushes the neck lifting pad 407 to rise through the connecting shaft 406. The neck lifting pad 407 raises the patient's neck. The forehead limiting plate 109 restricts the forehead of the patient's head, thereby tilting the patient's head back, so that the patient's mouth, pharynx, and larynx are in a straight line, so that the patient's airway is opened, so as to fully expose the trachea and facilitate the insertion of the tube.

[0055] Specifically, the working principle of this anesthesia intubation assistance device is as follows: The device is fixed to the hospital bed, and the patient places their head on the soft pad 11. Medical staff rotate the handle 106, which drives the spiral rod 105 to rotate. This causes the spiral rod 105 to move the sliding slider 104 within the clamping groove 103. The sliding slider 104 then drives the clamping frame 107 and the sponge clamping pillow 108 to clamp and fix the patient's head, preventing catheter dislodgement or bending caused by head movement during surgery. The forehead limiting plate 109 prevents the patient's head from dislodging during clamping, thus improving the efficiency and quality of the surgery. During head clamping, the sliding block 104 moves the L-shaped compression rod 201 into the air box 206, causing the L-shaped compression rod 201 to push the compression plate 207 to move. The compression plate 207 compresses the gas inside the air box 206. Because the through hole 208 is connected to the transmission chamber 202, the compressed gas is transported through the through hole 208 into the transmission chamber 202 and then through the connecting pipe 203 into the clamping box 204, thereby causing the inflatable airbag 205 to inflate. After the inflatable airbag 205 inflates, it compresses the front of the patient's cheek, opening the patient's mouth and making it easier for medical staff to accurately insert the catheter into the patient's mouth.

[0056] When the clamping box 204 moves toward the patient's face, it drives the moving box 301 to move, which in turn drives the lifting block 303 to move. Guided by the sliding column 304 on the inclined plate 305, the lifting block 303 descends during its lateral movement. This movement causes the limiting guide column 309 to descend, which in turn causes the connecting box 31 and the limiting slide rod 32 to descend. The limiting slide rod 32 then drives the arc-shaped compression hose 33 to compress the patient's jaw. The arc-shaped compression hose 33 can be moved by the connecting spring 34 to allow the patient's jaw to move further, facilitating a wider mouth opening, preventing injury during intubation, and improving the efficiency of intubation procedures for medical staff. The moving box 301 squeezes the slope of the trapezoidal block 401, causing the trapezoidal block 401 to descend. Because the limiting frame 404 laterally limits the transverse sliding rod 403, after the trapezoidal block 401 descends, the transverse sliding rod 403 is located at the top of the inclined groove 402. The transverse sliding rod 403 pushes the push plate 405 to move. The push plate 405 pushes the neck lifting pad 407 to rise through the connecting shaft 406. The neck lifting pad 407 raises the patient's neck. The forehead limiting plate 109 restricts the patient's forehead, causing the patient's head to tilt backward, so that the patient's mouth, pharynx, and larynx are in a straight line, so that the patient's airway is opened, so as to fully expose the trachea and facilitate the insertion of the tube.

[0057] When the limiting guide post 309 descends, it pulls the guide frame 504 downwards. When the rotating rod 502 slides in the straight groove of the guide groove 505, the rotating rod 502 drives the gear 503 to contact the toothed plate 507. The gear 503 drives the rotating rod 502 to rotate, and the rotating rod 502 drives the pressure handle 601 to rotate. The pressure handle 601 drives the tongue depressor 602 to be inserted into the patient's mouth. When the rotating rod 502 moves to the inclined groove of the guide groove 505, the gear 503 disengages from the toothed plate 507, and the rotating rod 502 moves to the top of the guide groove 505. The rotating rod 502 drives the pressure handle 601 and the tongue depressor 602 to press down on the patient's tongue root, thereby exposing the patient's throat. The lighting lamp 604 illuminates the patient's epiglottis and glottis, and the miniature camera 603 transmits the image to the display 605 for observation by medical staff, facilitating intubation.

[0058] It should be noted that the specific models and specifications of the miniature camera 603, the lighting lamp 604, and the display 605 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0059] The miniature camera 603, the lighting lamp 604, and the display 605, and their principles, are clear to those skilled in the art and will not be described in detail here.
