Description

Technical Field

[0001] The invention relates to the technical field of medical equipment, and in particular to a nasotracheal intubation fixing device. Background Art

[0002] Nasal endotracheal intubation is a common method for establishing an artificial airway in respiratory medicine. Currently, there are mainly the following methods for fixing endotracheal intubation:

[0003] 1. Adhesive tape: Use traditional adhesive tape or new type of fixed adhesive tape, cross-apply to the face and neck, use fewer instruments, and save money. However, sticking it directly on the skin, especially the corners of the mouth, back, and neck, can cause pressure injuries to the corners of the mouth. Although many gauze pads are added now, direct pressure on the skin and corners of the mouth will still make the patient feel uncomfortable;

[0004] 2. Endotracheal tube fixator: It is a patented new device that uses a round, relatively narrow device similar to a neck collar to fix the neck and mouth, and does not stick directly to the skin without tape. Insert the fixed plug into the dental pad in the mouth, let the endotracheal tube pass through the middle part of the fixture, and fix the endotracheal tube to the fixture with tape to increase the patient's comfort. The patient experience is better, and the patient's compliance can be increased accordingly. The disadvantage is that the price is relatively expensive.

[0005] In actual clinical practice, since the second tracheal fixation method is more expensive and there are more ordinary people among the patients, the first tracheal fixation method is used more frequently. However, the first method has obvious disadvantages. First, using tape to fix the trachea may cause damage to the patient. Secondly, the tape fixation method is very inefficient, requiring medical staff to frequently cut the tape and wrap the tape around the trachea to fix it. Therefore, each tracheal fixation and removal is a relatively cumbersome step. Therefore, it is necessary to design a nasotracheal intubation fixation device that is more comfortable and does not require an expensive price, so that ordinary patients will not experience discomfort when using it. Summary of the invention

[0006] The embodiment of the present invention provides a nasotracheal tube fixing device to solve the above-mentioned technical problems.

[0007] The embodiment of the present invention adopts the following technical scheme: a nasal endotracheal tube fixing device, comprising a fixing belt wrapped around the patient's head and a nose cuff connected to the fixing belt, wherein the nose cuff is located at the patient's nose and covers the nose when it is fixed on the patient's face in cooperation with the fixing belt; a connecting component is installed on one side of the nose cuff, a mounting plate is installed on one side of the connecting component, a driving component is arranged in the mounting plate, a protective frame is installed on one side of the mounting plate, a transmission component is installed in the protective frame, and the transmission component is connected to the working end of the driving component; two groups of symmetrically arranged fixing components are connected to the transmission component, one end of the two groups of fixing components is located in the protective frame and connected to the transmission component, and the other end of the two groups of fixing components is located at the lower end of the nasal cavity for fixing the nasal endotracheal tube.

[0011] Furthermore, matching holes are symmetrically provided on both sides of the protective frame, and the two matching holes are used to match the two sets of fixing components to operate in the protective frame. The matching holes are mainly used to match the two sets of fixing components to have enough space to unfold when they are driven by the transmission component to operate.

The use of the card slot assembly form facilitates the disassembly and assembly between the two, and is more convenient when replacing the rubber pad.

[0017] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0018] First, the technical solution adopted in the present application is mainly aimed at fixing the nasal endotracheal tube, and compared with the traditional means, the structure in the present application does not touch the patient's skin when fixing the nasal endotrachea. The main structure adopts a fixing belt and a nose cuff for fixing on the patient's head. When in use, the fixing belt is wrapped around the patient's head, the nose cuff is placed on the patient's nose, and the structure for fixing the nasal endotracheal tube is installed on the nose cuff so that it is suspended under the nasal cavity. In this way, the problem that the endotracheal tube fixer used in the prior art to fix the nasal endotracheal tube in the patient's nasal cavity needs to contact the patient's skin, and the equipment is easy to cause discomfort to the patient when used for a long time is solved.

[0019] Second, in the present application, a connecting component is installed on the nose sleeve to set a mounting plate, the mounting plate is suspended at one side under the nose through the connecting component, the protective frame is installed on the side of the mounting plate close to the nasal cavity, the driving component and the transmission component are respectively installed in the mounting plate and the protective frame and the two are interconnected, and the fixing component is installed in the transmission component and is located at the lower end of the nasal cavity. The driving component and the transmission component can drive the fixing component to operate through the cooperation of the driving component and the transmission component, so that the fixing component can fix the nasal trachea located in the nasal cavity under the nasal cavity. In this way, the problem that the adhesive tape used to fix the patient in the prior art is cumbersome, inefficient and requires frequent replacement is solved.

[0020] Third, in the present application, since the upper end of the nose band fits the face farther than the lower end, when the structure on the nose band generates a downward force, the design of the shape of the nose band can limit the nose band through the nose to a large extent, so that the nose band can withstand this part of the downward force.

[0021] Fourth, in the present application, the return force of the spring can play a role in supporting the sliding connection block. In this case, the threaded surfaces between the threaded rod and the threaded sleeve will conflict with each other and produce a certain friction force. At this time, the threaded rod will not be easily rotated in the threaded sleeve without being pressed by external force, so the spring can play a certain fixing role. This role can prevent the two sets of fixing components from loosening when fixing the nasal trachea.

[0022] Fifth, in the present application, the advantage of installing a rubber pad in the clamp is that when the clamp fixes the nasal trachea, the rubber pad contacts the nasal trachea, thereby preventing the problem of damage to the nasal trachea caused by long-term fixation of the clamp on the nasal trachea.

[0023] Sixth, in the present application, by replacing rubber pads with different inner diameters, the sizes of the insides of the two clamps can be different, so as to accommodate nasal tracheas of different sizes.

[0024] 7. In the present application, a mounting groove is provided in the fixture and a mounting block is provided on the rubber pad so that the rubber pad can be installed in the fixture in the form of a slot assembly. This installation method facilitates the disassembly and assembly between the two and is more convenient when replacing the rubber pad.

[0025] 8. In the present application, the mounting slider can slide in the fixed mounting frame to adjust the distance between the mounting plate and the nose sleeve band. In this way, the position between the fixed component and the nasal cavity can be adjusted, thereby increasing the practicality of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following is combined with Figure 1-7 As shown, the technical solutions provided by each embodiment of the present invention are described in detail.

[0038] An embodiment of the present invention provides a nasotracheal intubation fixing device, comprising a fixing belt 1 wrapped around the patient's head and a nose cuff 2 connected to the fixing belt 1, wherein the nose cuff 2 is located at the patient's nose and covers the nose when it is fixed on the patient's face in cooperation with the fixing belt 1; a connecting component 3 is installed on one side of the nose cuff 2, a mounting plate 4 is installed on one side of the connecting component 3, a driving component 6 is arranged in the mounting plate 4, a protective frame 5 is installed on one side of the mounting plate 4, a transmission component 7 is installed in the protective frame 5, and the transmission component 7 is connected to the working end of the driving component 6; two groups of symmetrically arranged fixing components 8 are connected to the transmission component 7, one end of the two groups of fixing components 8 are located in the protective frame 5 and connected to the transmission component 7, and the other end of the two groups of fixing components 8 are located at the lower end of the nasal cavity for fixing the nasotrachea.

[0039] The technical solution adopted in the present application is mainly aimed at fixing the nasal endotracheal tube, and compared with traditional means, the structure in the present application does not touch the patient's skin when fixing the nasal endotrachea. The main structure adopts a fixing belt 1 and a nose cuff 2 for fixing on the patient's head. When in use, the fixing belt 1 is wrapped around the patient's head, and the nose cuff 2 is placed on the patient's nose. The connecting component 3 is installed on the nose cuff 2 for setting the mounting plate 4. The mounting plate 4 is suspended on one side under the nose through the connecting component 3. The protective frame 5 is installed on the side of the mounting plate 4 close to the nasal cavity. The driving component 6 and the transmission component 7 are respectively installed in the mounting plate 4 and the protective frame 5. The two are connected to each other, and the fixing component 8 is installed in the transmission component 7 and is located at the lower end of the nasal cavity. The cooperation between the driving component 6 and the transmission component 7 can drive the fixing component 8 to operate, so that the fixing component 8 can fix the nasal trachea in the nasal cavity below the nasal cavity, and the fixing component 8 will not contact the patient's skin. In this way, the problem that the endotracheal tube fixer in the prior art needs to contact the patient's skin when fixing the nasal trachea in the patient's nasal cavity, and the equipment is likely to cause discomfort to the patient when used for a long time, is first solved. Secondly, the problem that the adhesive tape used in the prior art is cumbersome, inefficient and requires frequent replacement when fixing the patient is solved.

[0040] Preferably, the shape of the nose band 2 is consistent with the shape of the nose and fits on the nose when installed.

[0041] In the present application, the advantage of setting the shape of the nose band 2 to be consistent with the shape of the nose is that it will not cause an uncomfortable squeezing feeling to the patient when it is fixed on the patient's face, and when the structure is installed on the nose band 2, the upper end of the nose band 2 fits the face farther than the lower end, so when the structure on the nose band 2 generates a downward force, the design of the shape of the nose band 2 can limit the nose band 2 to a large extent through the nose, so that the nose band 2 can withstand this part of the downward force.

[0042] Preferably, the connecting component 3 includes a fixed mounting frame 31 and a mounting slider 32, the fixed mounting frame 31 is arranged on the side end of the nose sleeve band 2, the mounting slider 32 is slidably arranged in the fixed mounting frame 31, a positioning pin 33 is provided at the upper end of the fixed mounting frame 31, and a plurality of fixed card grooves 34 distributed at equal intervals are provided on the mounting slider 32, when the mounting slider 32 slides in the fixed mounting frame 31, the fixed end of the positioning pin 33 can correspond one-to-one with the plurality of fixed card grooves 34, and the side end of the mounting slider 32 is connected to the mounting plate 4.

[0043] In the present application, the fixed mounting frame 31 is used to be installed on the nose sleeve band 2, the mounting slider 32 is used to connect the mounting plate 4, and the mounting slider 32 can slide in the fixed mounting frame 31 to adjust the distance between the mounting plate 4 and the nose sleeve band 2. In this way, the position between the fixed component 8 and the nasal cavity can be adjusted.

[0044] Preferably, a hollow groove 41 is provided inside the mounting plate 4, and two sliding grooves 42 are symmetrically opened on both sides of the hollow groove 41 in the mounting plate 4, and a limiting rod 43 and a spring 44 are installed in each of the sliding grooves 42, and each of the springs 44 surrounds a limiting rod 43, and the two limiting rods 43 and the two springs 44 are connected to the driving assembly 6.

[0045] In the present application, the empty slot 41 provided in the mounting plate 4 is used to cooperate with the mounting plate 4 to place the driving assembly 6, and the two sliding slots 42 and the limiting rod 43 and spring 44 provided in the sliding slot 42 are all used to connect with the driving assembly 6. The limiting rod 43 is used to limit the driving assembly 6, and the spring 44 can play an auxiliary role.

[0046] Preferably, the protective frame 5 is symmetrically provided with matching holes 51 on both sides, and the two matching holes 51 are used to match the two groups of fixing components 8 to operate in the protective frame 5. The protective frame 5 is mainly used to install the transmission component 7, and the matching holes 51 on both sides are mainly used to match the two groups of fixing components 8 to have enough space to unfold when being driven by the transmission component 7 to operate.

[0047] Preferably, the driving assembly 6 comprises a threaded sleeve 61, a threaded rod 62, a knob 63, a connecting plate 64 and a sliding plate 65, wherein the threaded sleeve 61 is mounted on the mounting plate 4 and is located on one side of the empty slot 41, the threaded rod 62 is mounted in the threaded sleeve 61 in a threaded connection manner, one end of the threaded rod 62 is located in the empty slot 41, and the other end of the threaded rod 62 is located outside the mounting plate 4, the knob 63 is mounted on the other end of the threaded rod 62, the connecting plate 64 is mounted on one end of the threaded rod 62 located in the empty slot 41, and the connecting plate 64 is connected to the mounting plate 4. The threaded rod 62 is rotatably connected; one end of the sliding plate 65 is located in the empty groove 41 and fixedly connected to the connecting plate 64, two sliding connection blocks 66 are symmetrically arranged on both sides of one end of the sliding plate 65, each of the sliding connection blocks 66 is located in a sliding groove 42 and slidably connected to a limit rod 43, and each of the sliding connection blocks 66 is also connected to a spring 44, the other end of the sliding plate 65 is located in the protective frame 5, and two rows of tooth grooves 67 are symmetrically opened on both sides of the other end of the sliding plate 65, and the sliding plate 65 is connected to the transmission assembly 7 through the two rows of tooth grooves 67.

[0048] In the present application, the threaded sleeve 61 is used to be installed on the mounting plate 4 to connect the threaded rod 62. The threaded rod 62 can move toward the empty slot 41 when rotating in the threaded sleeve 61 through the knob 63, and can move toward the outside of the mounting plate 4 by rotating in the opposite direction. When the threaded rod 62 rotates toward the empty slot 41, it can drive the sliding plate 65 to move in the empty slot 41. When the sliding plate 65 moves, it is restricted by the two sliding connection blocks 66 that cooperate with the limit rod 43 in the sliding slot 42 and will not deviate. The movement of the sliding plate 65 can drive the transmission assembly 7 to operate through the two rows of tooth grooves 67.

[0049] The spring 44 can be used to assist the sliding connection block 66 in supporting the sliding connection block 66. When the threaded rod 62 drives the sliding block to move in the empty groove 41, the sliding connection block 66 will squeeze the spring 44 in the sliding groove 42 after the movement is completed. The recoil force generated by the squeezing of the spring 44 can reset the sliding connection block 66. However, since the movement of the threaded rod 62 in the threaded sleeve 61 requires rotation, the recoil force of the spring 44 cannot reset the sliding connection block 66. Therefore, the recoil force of the spring 44 can support the sliding connection block 66 at this time. In this case, the threaded surfaces of the threaded rod 62 in the threaded sleeve 61 will conflict with each other and generate a certain friction force. At this time, the threaded rod 62 will not be easily rotated in the threaded sleeve 61 without being pressed by external force, so the spring 44 can play a certain fixing role. This role can prevent the two sets of fixing components 8 from loosening when fixing the nasal trachea.

[0050] Preferably, the transmission assembly 7 includes two rotating connecting rods 71 ​​and two gears 72, the two rotating connecting rods 71 ​​are symmetrically arranged in the protective frame 5, the two rotating connecting rods 71 ​​are rotatably installed in the protective frame 5, and the two rotating connecting rods 71 ​​are arranged at intervals, each of the rotating connecting rods 71 ​​is connected to a group of fixed components 8, each of the gears 72 is installed on a rotating connecting rod 71, and the two gears 72 are respectively located on both sides of the sliding plate 65 and are engaged with the tooth grooves 67 provided on the sliding plate 65.

[0051] In the present application, the sliding plate 65 can move between the two gears 72 when it moves in the empty slot 41 toward the protective frame 5. The sliding plate 65 can drive the two gears 72 to rotate through the two rows of tooth grooves 67 provided at the other end thereof. And because the sliding plate 65 drives the two gears 72 to rotate between the two gears 72, the two gears 72 will rotate relative to each other. When the two gears 72 rotate, they can drive the two rotating connecting rods 71 ​​to rotate, so that the two rotating connecting rods 71 ​​can drive the two sets of fixed components 8 to operate.

[0052] Preferably, each group of the fixing assembly 8 includes a connecting sleeve 81, a connecting frame 82 and a clamp 83, the connecting sleeve 81 is installed on one end of the connecting frame 82, the connecting sleeve 81 is installed on a rotating connecting rod 71, the side of the connecting frame 82 close to the connecting sleeve 81 is located in the matching hole 51, and the clamp 83 is arranged on the other end of the connecting frame 82, and the inner side of the clamp 83 is semicircular in shape.

[0053] In the present application, the connecting frame 82 is connected to the rotating connecting rod 71 through the connecting sleeve 81, so that it can rotate along with the rotating connecting rod 71 when the rotating connecting rod 71 rotates. When the connecting frame 82 rotates, it can drive the clamp 83 to rotate synchronously. When the two clamps 83 operate at the same time, they can move relative to each other. When the two clamps 83 are in contact, a circle is formed inside them, which can fix the nasal trachea in the middle position.

[0054] Preferably, a rubber pad 85 is installed in each of the clamps 83 , and the shape of the rubber pad 85 is consistent with the shape of the inner side of the clamp 83 .

[0055] In the present application, the advantage of installing the rubber pad 85 in the clamp 83 is that when the clamp 83 fixes the nasal trachea, the rubber pad 85 contacts the nasal trachea, which can prevent the problem of damage to the nasal trachea caused by long-term fixation of the nasal trachea by the clamp 83. In addition, the shape of the rubber pad 85 is consistent with the inner side of the clamp 83, that is, when the two clamps 83 are in contact, the two rubber pads 85 inside them will also contact each other to form a circle. In this case, only the rubber pads 85 with different inner diameters need to be replaced to make the sizes of the insides of the two clamps 83 different, so as to adapt to nasal tracheas of different sizes.

[0056] Preferably, each of the clamps 83 is provided with a plurality of mounting grooves 84 at equal intervals, and each of the rubber pads 85 is provided with a plurality of mounting blocks 86 at equal intervals on the side in contact with the inner wall of the clamp 83; when the rubber pads 85 are installed in the clamp 83, each mounting block 86 is located in a mounting groove 84.

[0057] In the present application, a mounting groove 84 is provided in the clamp 83 and a mounting block 86 is provided on the rubber pad 85 so that the rubber pad 85 can be installed in the clamp 83 in the form of a slot assembly. This installation method facilitates disassembly and assembly between the two and is more convenient when replacing the rubber pad 85.
