Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of door teeth protection sleeves, and particularly relates to a tracheal intubation door teeth protection sleeve. BACKGROUND

[0002] The door teeth protection sleeve is a medical auxiliary device used in the operation of tracheal intubation, and its main function is to protect the teeth of a patient from damage that may occur in the process of intubation. In the process of tracheal intubation, the patient often cannot effectively cooperate and may struggle, which may cause the tracheal intubation to contact and collide with the teeth, thereby causing damage to the teeth. In addition, some tools and operations used in intubation may also indirectly cause damage to the teeth.

[0003] The utility model with the authorized publication number CN207768876U discloses a tracheal intubation door teeth protection sleeve, which comprises a mouthpiece, a tooth support pad and a door teeth protection plate. The mouthpiece comprises a front tooth blocking plate, a bite pad and a rear tooth blocking plate from outside to inside. The door teeth protection plate is attached to the bottom surface of the inner side of the rear tooth blocking plate and the middle part of the bite pad. The bottom of the mouthpiece at both ends is bent forward to form a U-shaped groove, and the tooth support pad is fixedly inserted into the U-shaped groove.

[0004] The above technical scheme uses the tooth support pad to support the oral cavity of the patient, which facilitates the medical staff to perform intubation. The door teeth protection plate can effectively protect the teeth or gums of the upper jaw and prevent damage to them when a laryngoscope with an intubation tube is used. The two sides of the mouthpiece are made of flexible material, which facilitates the adjustment of the bending degree of the mouthpiece and is suitable for most patients. The overall structure is simple and easy to mass-produce. However, the above technical scheme does not have the function of limiting the trachea, which may cause the device to shake after the trachea is inserted, thereby easily causing friction with the door teeth protection sleeve and affecting the patient.

[0005] Therefore, the present application provides a tracheal intubation door teeth protection sleeve to solve the above problems. CONTENT OF THE UTILITY MODEL

[0006] The purpose of the present application is to solve the problem of inconvenience in limiting the trachea during the use of the device in the prior art, and to provide a tracheal intubation door teeth protection sleeve.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A protective sleeve for endotracheal intubation incisors includes an upper protective sleeve and a lower protective sleeve below the upper protective sleeve. A fixing frame is provided on the outer side of the lower protective sleeve. Two limiting blocks are slidably connected to the inner wall of the fixing frame. Each limiting block has a limiting post slidably connected to its inner wall. The ends of the two limiting posts that are far apart from each other are fixedly connected to the inner wall of the fixing frame. Springs are fixedly connected to the sides of the two limiting blocks that are far apart from each other. The sides of the two springs that are far apart from each other are fixedly connected to the inner wall of the fixing frame. An inclined moving block is fixedly connected to the front of each limiting block. The outer surface of each inclined moving block is slidably connected to the inner wall of the fixing frame. A screw is rotatably connected to the inner wall of the fixing frame. An inclined push plate is threadedly connected to the outer surface of the screw. The outer surface of the inclined push plate is slidably connected to the inner wall of the fixing frame and contacts the outer surface of the inclined moving block.

[0009] Preferably, an upper anti-wear pad is fixedly connected to the outer surface of the upper protective sleeve, and a lower anti-wear pad is fixedly connected to the outer surface of the lower protective sleeve.

[0010] Preferably, the bottom surface of the upper anti-wear pad is fixedly connected to two elastic connecting strips, and the bottom surface of each elastic connecting strip is fixedly connected to the upper surface of the lower anti-wear pad.

[0011] Preferably, a connecting block is fixedly connected to the back of the fixed frame, and the outer surface of the connecting block is fixedly connected to the outer surface of the lower protective sleeve.

[0012] Preferably, reinforcing blocks are fixedly connected to both sides of the connecting block, and the outer surface of each reinforcing block is fixedly connected to the outer surface of the lower protective sleeve.

[0013] Preferably, a rotating block is fixedly connected to the end of the screw away from the fixed frame, and the outer surface of the rotating block is provided with anti-slip grooves arranged at equal intervals.

[0014] Preferably, each of the two limiting posts has a plug fixedly connected to one end that is close to the other, and the two plugs have their opposite sides in contact with the opposite sides of the two limiting blocks.

[0015] In summary, the technical effects and advantages of this application are as follows:

[0016] 1. By setting up a screw, inclined push plate, inclined moving block, limit block, spring, and limit post, the screw can be rotated quickly when manually turned by the operator. The rotation of the screw drives the inclined push plate to move. During the movement of the inclined push plate, it pushes the inclined moving blocks on both sides to move. The inclined moving blocks drive the limit blocks to move to both sides to open. At the same time, the limit blocks can compress the springs when they move. Conversely, the springs can help the limit blocks close and reset. Thus, with the cooperation of the inclined push plate and the spring, the opening and closing effect of the limit blocks can be controlled, which can conveniently limit the air tube inside the limit blocks and prevent shaking during use.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A protective sleeve for the incisors of an endotracheal tube includes an upper protective sleeve 1, a lower protective sleeve 2 below the upper protective sleeve 1, a fixing frame 3 on the outer side of the lower protective sleeve 2, an upper anti-wear pad 4 fixedly connected to the outer surface of the upper protective sleeve 1, and a lower anti-wear pad 5 fixedly connected to the outer surface of the lower protective sleeve 2. By setting the upper anti-wear pad 4 and the lower anti-wear pad 5, friction between the endotracheal tube and the protective sleeve can be prevented, thus avoiding damage to the endotracheal tube.

[0024] The inner wall of the fixed frame 3 is slidably connected to two limiting blocks 9, and the inner wall of each limiting block 9 is slidably connected to a limiting post 15. The bottom surface of the upper anti-wear pad 4 is fixedly connected to two elastic connecting strips 6, and the bottom surface of each elastic connecting strip 6 is fixedly connected to the upper surface of the lower anti-wear pad 5. By setting the elastic connecting strips 6, the upper protective sleeve 1 and the lower protective sleeve 2 can be connected, which makes it convenient for staff to pick up and use.

[0025] The ends of the two limiting posts 15 that are far apart from each other are fixedly connected to the inner wall of the fixed frame 3. The sides of the two limiting blocks 9 that are far apart from each other are fixedly connected to springs 16. The back of the fixed frame 3 is fixedly connected to a connecting block 7. The outer surface of the connecting block 7 is fixedly connected to the outer surface of the lower protective sleeve 2. By setting the connecting block 7, the fixed frame 3 can be fixed on the lower protective sleeve 2, so that it can be used stably.

[0026] The two springs 16 are fixedly connected to the inner wall of the fixed frame 3 on their opposite sides. Each limiting block 9 is fixedly connected to the front of an inclined moving block 12. Both sides of the connecting block 7 are fixedly connected to reinforcing blocks 8. The outer surface of each reinforcing block 8 is fixedly connected to the outer surface of the lower protective sleeve 2. By setting the reinforcing blocks 8, the stability of the connecting block 7 can be further increased, making it more secure for use.

[0027] The outer surface of each inclined moving block 12 is slidably connected to the inner wall of the fixed frame 3. The inner wall of the fixed frame 3 is rotatably connected to a screw 10. The outer surface of the screw 10 is threadedly connected to an inclined push plate 11. The end of the screw 10 away from the fixed frame 3 is fixedly connected to a rotating block 13. The outer surface of the rotating block 13 is provided with anti-slip grooves 14 arranged at equal intervals. By setting the rotating block 13 and the anti-slip grooves 14, the screw 10 can be rotated easily by the rotating block 13. At the same time, the anti-slip grooves 14 can prevent the hand from slipping.

[0028] The outer surface of the inclined push plate 11 is slidably connected to the inner wall of the fixed frame 3. The outer surface of the inclined push plate 11 is in contact with the outer surface of the inclined moving block 12. The ends of the two limiting posts 15 that are close to each other are fixedly connected with plugs 17. The sides of the two plugs 17 that are far apart from each other are in contact with the sides of the two limiting blocks 9 that are close to each other. By setting the plugs 17, the stability of the limiting blocks 9 can be increased, and the limiting blocks 9 can be prevented from falling off the limiting posts 15.

[0029] The working principle of this utility model is as follows: In use, the operator first places the device in a suitable position. Then, when protection of the patient's incisors is needed, the operator places the upper protective sleeve 1 and the lower protective sleeve 2 onto the patient's incisors respectively, thus protecting them and preventing damage. This also prevents damage to the trachea. The operator then inserts the endotracheal tube into the patient's trachea. Subsequently, the operator rotates the screw 10 by rotating block 13. When the operator manually rotates the screw 10, it rotates rapidly. This rotation drives the inclined push plate 11 to move. During this movement, the inclined push plate 11 pushes the inclined moving blocks 12 on both sides to move. The movable block 12 can drive the limiting block 9 to move to both sides to open. At the same time, the limiting block 9 can squeeze the spring 16 when it moves until the two limiting blocks 9 move to the appropriate position. Then, the staff puts the inserted air tube into the two limiting blocks 9. Finally, the screw 10 is rotated in the opposite direction. When the screw 10 rotates, it can drive the inclined push plate 11 to move. When the inclined push plate 11 moves, it can gradually separate from the inclined movable block 12. At the same time, after the inclined movable block 12 separates from the inclined push plate 11, the spring 16 can push the inclined movable block 12 to move and contact the inclined push plate 11 again. Then, with the cooperation of the inclined push plate 11 and the spring 16, the inclined movable block 12 and the limiting block 9 can be reset and the air tube can be limited to prevent the air tube from shaking.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
