Description

Technical Field

[0001] The invention relates to the field of oral care, and in particular to a child oral cannula fixing device. Background Art

[0002] Oral intubation for children is a crucial operation in pediatric medicine. When children face respiratory diseases, surgical anesthesia, etc., oral intubation can ensure a smooth airway. Due to the relatively narrow structure of children's airways and unique physiological characteristics, intubation operations require higher precision. During the intubation process, it is necessary to choose a cannula of suitable size for children to avoid damage to the airway. The cannula with adjustable angle can be adapted according to the specific situation of the child's airway to improve the success rate of intubation. At the same time, a winding block is set to wind and store multiple pipes to make the operating space neater and more orderly. This not only facilitates the operation of medical staff and avoids the confusion of pipes, but also reduces the discomfort and potential risks caused by pipes to children. Oral intubation for children plays a key role in ensuring children's respiratory function, but the operation process needs to be extremely cautious, and professional medical staff need to carefully operate and manage according to the individual differences of children to ensure the safety and comfort of children.

[0003] However, it should be noted that child patients generally have low tolerance. If the intubation tube is fixed for a long time, it is likely to cause great discomfort to the child, causing the child to be disgusted or even tear the tube. The child tearing the intubation tube may cause the intubation tube to shift. The intubation tube will scratch and damage the airway mucosa during movement, causing airway bleeding and edema. In severe cases, it may cause airway tearing, affecting the normal structure and function of the airway, causing further aggravation of ventilation disorders. In addition, the child's skin is relatively tender. The use of traditional medical tape will cause the tape to fall off repeatedly due to the child's dishonesty. In this process, the child's skin will be greatly damaged and uncomfortable. Once the intubation tube is damaged or displaced, medical staff need to re-intubate. After the previous tossing, the child will be more fearful and uncooperative, making it much more difficult to intubate again. Moreover, frequent intubation operations will further damage the airway, prolong the child's recovery time, and increase treatment costs and consumption of medical resources. Summary of the invention

[0004] In order to make up for the above deficiencies, the present invention provides a child oral cannula fixing device that overcomes the above technical problems or at least partially solves the above problems.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A child oral cannula fixing device comprises a fan-shaped ring, a curved edge is fixedly connected to the protruding side of the fan-shaped ring, and a fitting component is provided on the side of the fan-shaped ring;

[0007] The fitting assembly comprises:

[0008] A transverse flexible groove plate, wherein the transverse flexible groove plate is fixedly connected to both ends of the sector ring, and a self-adhesive sheet is fixedly connected to the opposite side of the transverse flexible groove plate, and the adhesive side of the self-adhesive sheet faces away from the inner ring body of the sector ring;

[0009] A vertical flexible groove plate, wherein the vertical flexible groove plate is fixedly connected to the end of the horizontal flexible groove plate, and the vertical flexible groove plate is provided with a hanging ear groove;

[0010] Velcro, one end of which is wound and adhered to the side plate body of the vertical soft groove plate.

Combined with the sponge strip, after the device is worn, the sponge strip is located at the air outlet of the nostrils, which can allow a certain amount of exhaled air to pass through, thereby improving the comfort of the device. At the same time, the soft ear-hanging groove can be hung on the ear to further improve the installation stability of the device.

[0012] In one embodiment of the present invention, a sponge strip is fixedly connected to the middle portion of the concave side of the sector ring.

[0013] In one embodiment of the present invention, an adjustment component is provided on the curved edge at the front of the sector ring, and the adjustment component includes a mounting box, and the two side plates of the mounting box are clamped with racks, and turntables are provided on both sides of the inner wall of the box through movable shafts, and the opposite side of the turntable is fixedly connected with a toothed sector plate, and the toothed sector plate has a toothed groove on its plate body.

[0014] By setting an adjustment component, the adjustment component can be moved back and forth on the curved edge and set at different positions, so as to effectively adjust the position of the oral tube. The airway anatomical structure of children is narrower and more special than that of adults. For example, the epiglottis of children is relatively long and soft, and the glottis is higher and more forward. The intubation tube with adjustable angle and position can better adapt to these anatomical characteristics. During the intubation process, it can be flexibly adjusted according to the actual situation and more accurately aligned with the airway entrance, thereby improving the one-time success rate of intubation and reducing the damage to the children's airway caused by repeated intubation attempts. The physiological curvature of the airway of different children is different, and the adjustable intubation tube can be adapted according to the curvature of the individual airway. By adjusting the position and angle of the intubation tube to keep it consistent with the natural curvature of the airway, the compression and distortion of the airway by the intubation tube can be minimized, ensuring the smooth flow of gas in the airway and reducing airway resistance.

[0015] In one embodiment of the present invention, a first connecting plate is movably provided on the turntable via a movable shaft, the first connecting plate is located at the toothed groove portion of the toothed sector plate, a second connecting plate is movably provided at one end of the first connecting plate away from the turntable via a movable shaft, and a double insertion strip is fixedly connected to the opposite side of the second connecting plate.

[0016] In one embodiment of the present invention, a spring located outside the installation box is sleeved on the double insertion strip, a fixing ring is sleeved on the double insertion strip, the fixing ring is fixedly connected to the outer surface of the installation box, a pressing head is fixedly connected to the end of the double insertion strip, and the spring is located between the pressing head and the fixing ring.

[0017] In one embodiment of the present invention, pinching plates are fixedly connected to the four sides of the front side surface of the installation box, and circular holes are formed at the ends of the pinching plates.

[0018] In one embodiment of the present invention, a movable groove matched with the rack is provided on the body of the installation box, and a limiting edge located on the side surface of the body of the installation box is fixedly connected to the back of the rack.

[0019] In one embodiment of the present invention, a clamp is fixedly connected to the non-toothed side of the rack, and the clamp is clamped and connected to the curved edge.

[0020] In one embodiment of the present invention, the bottom of the fan-shaped ring is fixedly connected to a connecting block, the bottom of the fan-shaped ring is provided with an insertion tube assembly through the connecting block, the insertion rod assembly includes a storage tube, the side of the storage tube is provided with a side groove, one side of the bottom of the storage tube is fixedly connected to a winding block, one side of the bottom of the winding block is fixedly connected to a limiting strip, the other side of the bottom of the winding block is fixedly connected to a connecting skin, and the bottom of the winding block is fixedly connected to a cover plate through the connecting skin.

[0021] By setting up the intubation assembly and combining it with the winding block, it is convenient to wind and store multiple pipes. When children are intubated, multiple pipes are often connected at the same time, such as breathing tubes, monitoring tubes, etc. The winding block can wind these pipes together in an orderly manner, making the pipe layout clear and avoiding multiple pipes from being entangled or knotted. In emergency situations or when performing medical operations, medical staff can quickly and accurately find the required pipes, improving the efficiency and safety of the operation. The setting of the hoop can quickly disassemble the plugged pipe body, and the installation is tight, which has a stable effect on the packaging device.

[0023] The invention provides a child oral cannula fixing device, the beneficial effects of which include:

[0024] 1. By setting up the fitting component, the self-adhesive sheet of the fitting component can provide a certain comfort effect when the cannula is installed in the child's mouth and is not easy to fall off. Combined with the sponge strip, after the device is worn, the sponge strip is located at the air outlet of the nostril, which can allow a certain amount of exhaled air to pass through, improving the comfort of the device. At the same time, the soft ear-hanging groove can be hung on the ear, further improving the installation stability of the device.

[0025] 2. By setting an adjustment component, the adjustment component can be moved back and forth on the curved edge and set at different positions to facilitate effective adjustment of the position of the oral tube. The airway anatomical structure of children is narrower and more special than that of adults.

By adjusting the position and angle of the intubation tube to keep it consistent with the natural curvature of the airway, the compression and distortion of the airway by the intubation tube can be minimized, ensuring the smooth flow of gas in the airway and reducing airway resistance.

[0026] 3. By setting up the intubation assembly and combining it with the winding block, it is convenient to wind and store multiple pipes. When children are intubated, multiple pipes are often connected at the same time, such as breathing tubes, monitoring tubes, etc. The winding block can wind these pipes together in an orderly manner, making the pipe layout clear and avoiding multiple pipes from being entangled and knotted.

[0039] Example

[0040] See also Figure 1-8The present invention provides a technical solution: a child oral intubation fixing device, comprising a fan-shaped ring 1, a curved edge 102 is fixedly connected to the protruding side of the fan-shaped ring 1, a fitting component 2 is provided on the side of the fan-shaped ring 1, and the fitting component 2 includes: a horizontal soft groove plate 201, a vertical soft groove plate 202 and a magic patch 204, the horizontal soft groove plate 201 is fixedly connected to the two ends of the fan-shaped ring 1, a self-adhesive sheet 203 is fixedly connected to the opposite side of the horizontal soft groove plate 201, and the adhesive side of the self-adhesive sheet 203 faces away from the inner ring body of the fan-shaped ring 1, the vertical soft groove plate 202 is fixedly connected to the end of the horizontal soft groove plate 201, and an ear hanging groove 2021 is provided on the vertical soft groove plate 202, and the magic patch 204 One end of the sticker 204 is wrapped and pasted on the side plate of the vertical soft groove plate 202. By setting the fitting component 2, the self-adhesive sheet 203 of the fitting component 2 can provide a certain comfort effect when the cannula is installed in the child's mouth and is not easy to fall off. Combined with the sponge strip 101, after the device is worn, the sponge strip 101 is located at the air outlet of the nostrils, which can allow a certain amount of exhaled air to pass through, thereby improving the comfort of the device. At the same time, the soft ear-hanging groove 2021 can be hung on the ear to further improve the installation stability of the device. The fan-shaped ring 1 is attached to the philtrum of the child, and the sponge strip 101 is attached to the philtrum to induce the child to bite the storage tube 401, and the main tube is inserted. After 402 is inserted into the oral cavity, it can be placed in the inner ring of the storage tube 401 through the side groove 4011. The other auxiliary tubes 4022 are similar. Then, medical tape is used to wrap around each tube body, and the cover plate 4043 is opened. The tail of the tape is placed between the cover plate 4043 and the winding block 404 and the cover plate 4043 is covered. The cover plate 4043 is then fixed by the limit strip 4042, and the threaded rod 4033 is rotated. The threaded rod 4033 is only threadedly connected to one of the double rods 4032, and the other is only plug-in. Under the action of the thread, the two rods are close or far away, which is reflected on the hoop 403 that the hoop 403 is tightened. Or loosen, this process can be used for the fastening and plugging of the main pipe 402 and the external pipe 4021, and the quick disassembly. When it is necessary to adjust the angle or position of the cannula assembly 4, press the pressing head 311, and under the action of the double rods 4032, the second connecting plate 307 drives the first connecting plate 306 to move, and the first connecting plate 306 causes the turntable 304 to rotate a certain angle, and the toothed fan-shaped plate 305 rotates to drive the rack 302 to move relative to each other and away from each other, so that the chuck 303 moves away, that is, the adjustment assembly 3 loosens the curved edge 102, and after adjusting to the appropriate position, loosen the pressing head 311 to perform the reverse action of the above action, that is, tightening.

[0041] See also Figure 1-8A sponge strip 101 is fixedly connected to the middle part of the concave side of the fan-shaped ring 1, so that after wearing, the gas exhaled from the nose can pass through the sponge strip 101 smoothly, avoiding the discomfort caused by the reflux of warm gas to the nose. Children themselves have a low tolerance for discomfort. If the warm gas refluxes into the nasal cavity after intubation, it will cause stuffiness, dampness and irritation in the nose, causing the child to feel obvious discomfort and cry and struggle. The sponge strip 101 allows the exhaled gas to be discharged smoothly without reflux, which can make the child's nose feel refreshed, greatly improve their comfort during intubation, and reduce the irritability caused by nasal discomfort.

[0042] See also Figure 1-8 An adjustment component 3 is provided on the curved edge 102 at the front of the sector ring 1. The adjustment component 3 includes an installation box 301. The two side plates of the installation box 301 are clamped with racks 302. A turntable 304 is provided on both sides of the inner wall of the box through a movable shaft. A toothed sector plate 305 is fixedly connected to the opposite side of the turntable 304. A toothed groove 3051 is provided on the plate body of the toothed sector plate 305. By setting the adjustment component 3, the adjustment component 3 can be moved back and forth on the curved edge 102, and it can be set at different positions, so as to effectively adjust the position of the nozzle. The airway anatomy of children is narrower and more special than that of adults. For example, children's epiglottis is relatively long and soft, and the glottis is higher and more forward. The intubation tube with adjustable angle and position can better adapt to these anatomical characteristics. During the intubation process, it can be flexibly adjusted according to the actual situation and more accurately aligned with the airway entrance, thereby improving the one-time success rate of intubation and reducing the damage to the children's airway caused by repeated intubation attempts. The physiological curvature of the airway varies among children, and the adjustable intubation tube can be adapted according to the curvature of the individual airway. By adjusting the position and angle of the intubation tube to keep it consistent with the natural curvature of the airway, the compression and distortion of the airway by the intubation tube can be minimized, ensuring the smooth flow of gas in the airway and reducing airway resistance.

[0043] See also Figure 1-8 A first connecting plate 306 is movably provided on the turntable 304 through a movable shaft. The first connecting plate 306 is located at the toothed groove 3051 of the toothed sector plate 305. A second connecting plate 307 is movably provided on one end of the first connecting plate 306 away from the turntable 304 through a movable shaft. A double insertion strip 308 is fixedly connected to the opposite side of the second connecting plate 307.

[0044] See also Figure 1-8 A spring 310 located outside the installation box 301 is sleeved on the double insertion strip 308, a fixing ring 309 is sleeved on the double insertion strip 308, and the fixing ring 309 is fixedly connected to the outer surface of the installation box 301. A pressing head 311 is fixedly connected to the end of the double insertion strip 308, and the spring 310 is located between the pressing head 311 and the fixing ring 309, so as to maintain the tightness of the device when no external force is applied.

[0045] See also Figure 1-8 The front surface of the installation box 301 is fixedly connected with a pinching plate 312 on all sides. The end of the pinching plate 312 is provided with a circular hole 3121. When pinching, the operator's finger flesh will enter the hole, which improves the friction effect and prevents slipping. In the medical operation process, especially when it involves key operations such as oral intubation, the stability of the operating component is very important. If the operator's hand is easy to slip when operating the pressing head, it may cause interruption or error of the operation. The finger flesh entering the hole improves the friction effect and prevents slipping, so that the operation can be carried out continuously and stably, reducing unnecessary stimulation and risks caused to children by interrupted operation.

[0046] See also Figure 1-8 A movable groove adapted to the rack 302 is provided on the body of the installation box 301 , and a limiting edge 3021 located on the side surface of the body of the installation box 301 is fixedly connected to the back of the rack 302 .

[0047] See also Figure 1-8 The non-toothed side of the rack 302 is fixedly connected with a clamp 303 , and the clamp 303 is clamped and connected to the curved edge 102 .

[0048] See also Figure 1-8 The bottom of the sector ring 1 is fixedly connected with a connecting block 405, and the bottom of the sector ring 1 is provided with an intubation assembly 4 through the connecting block 405. The insertion rod assembly includes a storage tube 401, and a side slot 4011 is opened on the side of the storage tube 401. A winding block 404 is fixedly connected to one side of the bottom of the storage tube 401, and a limiting strip 4042 is fixedly connected to one side of the bottom of the winding block 404. A connecting skin 4041 is fixedly connected to the other side of the bottom of the winding block 404. The bottom of the winding block 404 is fixedly connected with a cover plate 4043 through the connecting skin 4041. By setting the intubation assembly 4 and combining the winding block 404, it is convenient to wind and store multiple pipes. When children's oral intubation is performed, multiple pipes are often connected at the same time, such as a breathing tube, a monitoring tube, etc. The winding block 404 can be set to wind these pipes together in an orderly manner, so that the pipe layout is clear and multiple pipes are prevented from being entangled or tangled with each other. In emergency situations or when performing medical operations, medical staff can quickly and accurately find the required pipes, thereby improving the efficiency and safety of the operation. The setting of the hoop 403 can quickly disassemble the plugged pipe body and install it tightly, thereby achieving a stable effect of the packaging device.

[0049] See also Figure 1-8A main pipe 402 is provided in the receiving pipe 401, an external pipe 4021 is inserted in the main pipe 402, a hoop 403 is provided on the pipe body of the main pipe 402, a half pipe 4031 is fixedly connected on the hoop 403, a double rod 4032 is inserted in the half pipe 4031, a threaded rod 4033 is threadedly connected on the double rod 4032, and an auxiliary pipe 4022 located in the inner ring of the receiving pipe 401 is provided on one side of the main pipe 402.

[0050] Specifically, the working process or working principle of the child oral intubation fixing device is as follows: when in use, the fan-shaped ring 1 is fitted on the philtrum of the child, the sponge strip 101 is fitted on the philtrum, the child is induced to bite the storage tube 401, and the main tube 402 is inserted into the mouth and placed on the inner ring of the storage tube 401 through the side slot 4011. The other auxiliary tubes 4022 are similarly used, and then medical tape is used to wrap around each tube body, and the cover plate 4043 is opened, and the tail of the tape is placed between the cover plate 4043 and the winding block 404 and the cover plate 4043 is covered. The cover plate 4043 is then fixed by the limiting strip 4042, and the threaded rod 4033 is rotated. The threaded rod 4033 is only threadedly connected to one of the double rods 4032, and the other is only plugged in. Under the action of the thread, the two rod bodies move closer or farther away, which is reflected on the hoop 403 as the hoop 403 being tightened or loosened. This process can be used to tighten and plug the main pipe 402 and the external pipe 4021 and quickly disassemble them. When it is necessary to adjust the angle or position of the cannula assembly 4, the pressing head 311 is pressed. Under the action of the double rods 4032, the second connecting plate 307 drives the first connecting plate 306 to move. The first connecting plate 306 causes the turntable 304 to rotate a certain angle. The toothed sector plate 305 rotates to drive the rack 302 to move relative to each other and away from each other, so that the chuck 303 moves away. That is, the adjustment assembly 3 loosens the curved edge 102. After adjusting to the appropriate position, the pressing head 311 is released to perform the reverse action of the above action, that is, clamping.

[0051] It should be noted that the threaded rod 4033 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
