Description

Technical Field

[0001] This invention relates to the field of fixation device technology, and more specifically to a nasogastric tube fixation device. Background Technology

[0002] A nasogastric tube is a medical catheter inserted through the nasal cavity with its tip extending to the stomach or intestines. It is mainly used for enteral nutrition support or gastrointestinal decompression and is suitable for patients who are unable to eat independently, have swallowing difficulties, or have gastrointestinal obstruction.

[0003] To maintain the stability of the nasogastric tube during use, it needs to be fixed to the patient's face. Existing technologies can use medical tape for adhesion or employ a separate fixation device, such as the 3D-printed fixation device for the nasogastric tube disclosed in CN120549774A. This device itself is fixed to the patient's face with straps, and the nasogastric tube is then connected to the fixation device during use, thus achieving fixation of the nasogastric tube.

[0004] Furthermore, although the nasogastric tube is fixed in the existing technology, it is relatively loose and cannot be closely attached to the patient's face. This makes it very easy for the patient to pull on the nasogastric tube during activities, or even cause the nasogastric tube to dislodge. Once unplanned extubation occurs, it will not only delay the patient's recovery process, but also require reintubation, increasing the patient's pain and the workload of medical staff, thus seriously affecting the safety of clinical treatment. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a nasogastric tube fixation device. After the nasogastric tube is introduced behind the ear, it is clamped between two traction components. Pulling the nasogastric tube makes it slightly taut, which fits the patient's face better and reduces the probability of it being accidentally touched by other objects during use. Therefore, it reduces the probability of the nasogastric tube being pulled off and falling off from the root.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a nasogastric tube fixation device, comprising a fixation mask, an elastic band provided on the rear side of the fixation mask, a connecting frame fixed at both ends of the elastic band, an mounting plate fixed on one of the connecting frames, a canvas strap fixed at the outer end of the connecting frame, and the front ends of the two canvas straps fixedly connected to the two sides of the fixation mask respectively. A ring-shaped structure consisting of a fixation mask, elastic bands, and canvas straps is placed over the patient's head. The fixation mask is positioned above the nose and below the eyes, while the two connecting frames are fitted over the patient's two outer ears. This design ensures that the fixation mask is secured without avoiding the ears, thus preventing the elastic bands and canvas straps from shifting and affecting the stability of the fixation mask. The mounting plate is provided with a traction assembly on one side. The traction assembly includes two fixed shafts rotatably connected to one side of the mounting plate. A clamping wheel is fixedly provided on the side of the fixed shaft away from the mounting plate. The two clamping wheels are distributed vertically, and an annular groove is provided at the outer end of the clamping wheel. A first torsion spring is provided between the clamping wheel and the mounting plate. The first torsion spring is sleeved on the outer end of the fixed shaft. The two ends of the first torsion spring are fixedly connected to the mounting plate and the clamping wheel, respectively. A limiting channel is fixedly provided on the canvas strap on the side where the pulling assembly is located.

[0007] Furthermore, two arc-shaped clips are fixedly provided on the front side of the fixed mask, and a rubber pad is fixedly provided on the inner wall of the arc-shaped clips. The nasogastric tube is clamped between the two arc-shaped clips and in contact with the rubber pad.

[0008] Furthermore, the fixed mask is provided with two support components. Each support component includes a fixed clamp located at the rear of the fixed mask. The fixed clamp is elastic, and its top end bends forward to the front of the fixed mask to clamp it onto the fixed mask. A strip-shaped sponge pad is fixedly provided at the rear of the fixed clamp. The strip-shaped sponge pad is in direct contact with the patient's facial skin. The strip-shaped sponge pad is soft and elastic, and its contact with the patient's skin does not irritate the skin. It can also adjust the clamping position of the fixed clamp on the fixed mask, thereby adjusting the support position of the fixed mask on the patient's face. Moreover, the support components can increase the gap between the fixed mask and the patient's face, making the area covered by the fixed mask more ventilated and comfortable.

[0009] Furthermore, the lower side of the arc-shaped clip is provided with two nasal plug assemblies. Each nasal plug assembly includes a rubber plug with an insert that passes through it. The rubber plug is elastic, while the insert is not. A connecting strap is fixed to the top of the rubber plug and connected to the front of the fixed mask. The rubber plug is inserted into the corresponding nasal cavity of the patient. Then, the nasogastric tube passes through the rubber plug and is inserted into the patient's nasal cavity through the insert on the rubber plug. In this way, the nasogastric tube will not directly contact the nasal cavity. During the use of the nasogastric tube, the patient's head movement and breathing will cause the nasogastric tube to shake and rub in the nasal cavity. The rubber plug and the insert thus separate the nasogastric tube from the inner wall of the nasal cavity, preventing the nasogastric tube from shaking and irritating the inner wall of the nasal cavity.

[0010] Furthermore, a clamping assembly is provided on one side of another canvas strap. The clamping assembly includes a mounting piece fixedly mounted on the canvas strap. A connecting shaft is rotatably connected to one side of the mounting piece. An adjusting end block is fixedly provided at one end of the connecting shaft. A second torsion spring is provided between the adjusting end block and the mounting piece. The second torsion spring is sleeved on the outer end of the connecting shaft, and its two ends are fixedly connected to the mounting piece and the adjusting end block, respectively.

[0011] Furthermore, the adjustment end block is provided with a pressing rod that passes through the adjustment end block. One end of the adjustment end block is connected by a fastening bolt for fixing the pressing rod through a thread. One end of the pressing rod extends to the front side of the fixed mask and is rotatably connected to a pressing roller shaft. Before the insertion end of the nasogastric tube is inserted into the patient's body through the nostril, it needs to pass around the outer end of the pressing roller shaft. The pressing roller shaft can press on the patient's philtrum. The pressing rod can slide relative to the adjustment end block to adjust the position of the pressing roller shaft. After adjustment, tightening the fastening bolt can fix the position of the pressing roller shaft. The nasogastric tube passing between the pressing roller shaft and the patient is clamped and fixed at the patient's philtrum by the pressing roller shaft, but this does not affect the patency of the nasogastric tube.

[0012] Furthermore, a hollow wheel is fixedly provided at one end of the pressing roller shaft, and a detachable end plate is provided on one side of the hollow wheel. A sound-permeable mesh is embedded in the end plate, and the warning sound is transmitted outward through the sound-permeable mesh.

[0013] Furthermore, the hollow wheel is equipped with an impact ball inside, and multiple metal partitions are fixed on the inner wall of the hollow wheel. The distance between any two adjacent metal partitions is slightly larger than the diameter of the impact ball, and the internal depth of the hollow wheel is slightly larger than the diameter of the impact ball. Therefore, under normal circumstances, the impact ball will be clamped between two of the metal partitions and cannot move left or right. It can only make a sound as the hollow wheel rotates, thereby avoiding accidental contact caused by the patient's movement.

[0014] The technical effects and advantages of this invention are as follows: This invention fixes a fixed mask to the patient's face, then clamps the nasogastric tube in the arc-shaped clip at the front of the fixed mask, and then extends it through the limiting channel to behind the patient's ear, avoiding the extension to the front of the patient and swinging like a traditional nasogastric tube, thus avoiding discomfort to the patient. In addition, two support components are set on the fixed mask, which can easily adjust the pressure position on the face and avoid pressure sores. When fixing the fixed mask, by setting the connecting frame at the ears, the ears can be avoided when fixing the fixed mask, and the binding position can be avoided, thus avoiding affecting the stability of the binding. By setting two nasal plug components on the fixed mask, the rubber plug is fixed in the nasal cavity, and then the nasogastric tube is inserted into the patient's nasal cavity through the tube. This separates the inner wall of the nasal cavity from the nasogastric tube, preventing the nasogastric tube from moving and irritating the patient's nasal cavity, and avoiding increasing the patient's discomfort. By setting up a traction component, the nasogastric tube is introduced behind the ear and then clamped between two traction components. The clamping wheel is driven by the elastic force of the first torsion spring, which in turn pulls the nasogastric tube, making it slightly taut and more closely fit the patient's face. This reduces the probability of it being accidentally touched by other objects during use, thus fundamentally reducing the probability of the nasogastric tube being pulled off. The nasogastric tube is pressed and fixed in the patient's philtrum by a pressing roller. When pulled, the pressing roller rotates and drives the hollow wheel. The impact ball inside the hollow wheel collides with the inner wall of the hollow wheel and the metal partition, making a sound to alert the patient. This allows for timely detection of any abnormalities in the nasogastric tube, preventing further pulling and dislodgement from the patient's body, and greatly reducing the rate of unplanned removal of the nasogastric tube.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0018] Refer to the instruction manual appendix Figures 1-9The present invention provides a nasogastric tube fixation device, including a fixation mask 1. An elastic band 101 is provided on the rear side of the fixation mask 1. A connecting frame 103 is fixed at both ends of the elastic band 101. An mounting plate 4 is fixed on one of the connecting frames 103. A canvas strap 102 is fixed at the outer end of the connecting frame 103. The front ends of the two canvas straps 102 are respectively fixedly connected to the two sides of the fixation mask 1. Two arc-shaped clips 105 are fixedly provided on the front side of the fixed mask 1. A rubber pad is fixed on the inner wall of the arc-shaped clip 105. The nasogastric tube is clamped between the two arc-shaped clips 105 and in contact with the rubber pad.

[0019] The ring structure formed by the fixed mask 1, elastic band 101, and canvas strap 102 is placed on the patient's head. The fixed mask 1 is located on the patient's face, above the nose and below the eyes. The elasticity of the elastic band 101 fixes the fixed mask 1 to the patient's face. The two connecting frames 103 are respectively placed on the patient's two outer ears, so that the fixed mask 1 does not need to avoid the ears when binding it, thereby avoiding the positional displacement of the elastic band 101 and canvas strap 102 and affecting the stability of the fixed mask 1. After fixing the mask 1, leave a section of the nasogastric tube for insertion into the patient's body. The remaining section is held between the two arc-shaped clips 105 and in contact with the rubber pad. Use the arc-shaped clips 105 to clamp and fix the nasogastric tube. Then, pass the nasogastric tube through the limiting channel 104 and extend it behind the ear. The limiting channel 104 plays a limiting role, which can fix the nasogastric tube and prevent it from swinging and causing discomfort to the patient.

[0020] During use, the pressure point on the face can be adjusted to prevent pressure sores, such as... Figure 2 , Figure 3 and Figure 6 As shown, the fixed face mask 1 is provided with two support components 2. The support component 2 includes a fixed clamp 201 located on the rear side of the fixed face mask 1. The fixed clamp 201 is elastic. The top of the fixed clamp 201 is bent forward to the front side of the fixed face mask 1, thereby clamping the fixed clamp 201 on the fixed face mask 1. A strip-shaped sponge pad 202 is fixedly provided on the rear side of the fixed clamp 201. The strip-shaped sponge pad 202 directly contacts the patient's facial skin to improve the patient's comfort.

[0021] By attaching the fixation clamp 201 to the fixation mask 1, the strip sponge pad 202 is positioned behind the fixation mask 1 and placed between the fixation mask 1 and the patient's face, thereby supporting the fixation mask 1. The strip sponge pad 202 is soft and elastic, and does not irritate the patient's skin when in contact with it. It can also adjust the clamping position of the fixation clamp 201 on the fixation mask 1, thereby adjusting the support position of the fixation mask 1 on the patient's face and adjusting the pressure position on the patient's face, avoiding pressure sores caused by prolonged pressure on the same position. Furthermore, the support component 2 increases the gap between the fixation mask 1 and the patient's face, making the area covered by the fixation mask 1 more ventilated and comfortable.

[0022] To avoid irritating the patient's nasal cavity with the nasal gastrointestinal tube, such as Figure 3 , 7 As shown, the lower side of the arc-shaped clip 105 is provided with two nose plug assemblies 3. The nose plug assembly 3 includes a rubber plug 301. An insertion tube 302 is embedded in the rubber plug 301 and passes through the rubber plug 301. The rubber plug 301 is elastic, while the insertion tube 302 is not elastic. A connecting strap 303 is fixedly provided at the top of the rubber plug 301 and connected to the front side of the fixed mask 1. The connecting strap 303 can be detached from the fixed mask 1, thereby facilitating the replacement of the nose plug assembly 3.

[0023] Before the insertion end of the nasogastric tube enters the patient's nasal cavity, a rubber stopper 301 is first inserted into the corresponding nasal cavity. Then, the nasogastric tube passes through the insertion tube 302 on the rubber stopper 301 and is inserted into the patient's nasal cavity. In this way, the nasogastric tube will not directly contact the nasal cavity, but will contact the insertion tube 302. During the use of the nasogastric tube, the patient's head movement and breathing will cause the nasogastric tube to shake and rub in the nasal cavity. The rubber stopper 301 and the insertion tube 302 thus separate the nasogastric tube from the inner wall of the nasal cavity, preventing the nasogastric tube from shaking and irritating the inner wall of the nasal cavity, thereby avoiding discomfort to the patient.

[0024] By pulling the nasogastric tube with external force, it is slightly tightened to better fit the patient's face, such as... Figure 1 , Figure 8 As shown, a traction assembly 5 is provided on one side of the mounting plate 4. The traction assembly 5 includes two fixed shafts 502 rotatably connected to one side of the mounting plate 4. A clamping wheel 501 is fixed on the side of the fixed shaft 502 away from the mounting plate 4. The two clamping wheels 501 are distributed vertically. An annular groove is provided at the outer end of the clamping wheel 501. The nasogastric tube is fixed in the annular groove, which helps to keep the nasogastric tube stable during the fixation process. A first torsion spring 503 is provided between the clamping wheel 501 and the mounting plate 4. The first torsion spring 503 is sleeved on the outer end of the fixed shaft 502. The two ends of the first torsion spring 503 are fixedly connected to the mounting plate 4 and the clamping wheel 501 respectively. A limiting channel 104 is fixedly provided on the canvas strap 102 on the side where the pulling assembly 5 is located.

[0025] After passing through the limiting channel 104 from front to back, the nasogastric tube passes between two traction components 5. The distance between the two clamping wheels 501 is less than the cross-sectional diameter of the nasogastric tube, so the nasogastric tube can be clamped between the two clamping wheels 501 without affecting its patency. At this time, the first torsion spring 503 is in a tightened state. The elastic force of the first torsion spring 503 drives the fixed shaft 502 and the clamping wheels 501 to rotate. The nasogastric tube clamped between the two clamping wheels 501 is also pulled by the clamping wheels 501, so the nasogastric tube is slightly tightened. The tightened nasogastric tube fits the patient's facial skin better, so the probability of it being accidentally touched by other objects during use is lower. Therefore, the probability of the nasogastric tube being pulled off is reduced from the root.

[0026] One end of the nasogastric tube is tightened by the traction component 5, and the other end also needs to be secured; otherwise, the nasogastric tube will be pulled out of the patient's body. Figure 1 , Figure 4 and Figure 5 As shown, another canvas strap 102 has a clamping assembly 6 on one side. The clamping assembly 6 includes a mounting piece 605 fixedly mounted on the canvas strap 102. A connecting shaft 604 is rotatably connected to one side of the mounting piece 605. An adjusting end block 602 is fixedly mounted on one end of the connecting shaft 604. A second torsion spring 606 is provided between the adjusting end block 602 and the mounting piece 605. The second torsion spring 606 is sleeved on the outer end of the connecting shaft 604. The two ends of the second torsion spring 606 are fixedly connected to the mounting piece 605 and the adjusting end block 602, respectively.

[0027] The adjusting end block 602 is provided with a pressing rod 601 that passes through the adjusting end block 602. One end of the adjusting end block 602 is connected by a fastening bolt 607 for fixing the pressing rod 601 through a thread. One end of the pressing rod 601 extends to the front side of the fixed mask 1 and is rotatably connected to a pressing roller shaft 603. The pressing roller shaft 603 can press on the philtrum of the patient. The pressing rod 601 can slide relative to the adjusting end block 602 to adjust the position of the pressing roller shaft 603. After adjustment, tightening the fastening bolt 607 can fix the position of the pressing roller shaft 603.

[0028] Before the nasogastric tube is inserted into the patient's body through the nostril, the insertion end needs to pass around the outer end of the pressing roller shaft 603 and pass between the pressing roller shaft 603 and the patient. At this time, the second torsion spring 606 is in a tightened state. Its elastic force drives the connecting shaft 604 and the adjusting end block 602 to rotate and drive the pressing rod 601. The pressing roller shaft 603 at one end of the pressing rod 601 is also driven by the elastic force of the second torsion spring 606, clamping and fixing the nasogastric tube between the pressing roller shaft 603 and the patient at the philtrum of the patient, but without affecting the patency of the nasogastric tube.

[0029] When the nasogastric tube inserted into the patient's body is pulled by external force, it can issue a warning to prevent the tube from dislodging. Figure 4 , Figure 9 As shown, a hollow wheel 7 is fixedly provided at one end of the pressing roller shaft 603, and a detachable end plate is provided on one side of the hollow wheel 7, with a sound-permeable mesh embedded on the end plate.

[0030] The hollow wheel 7 has an impact ball 702 inside, and multiple metal spacers 701 are fixed on the inner wall of the hollow wheel 7. The distance between any two adjacent metal spacers 701 is slightly larger than the diameter of the impact ball 702, and the internal depth of the hollow wheel 7 is slightly larger than the diameter of the impact ball 702. Therefore, under normal circumstances, the impact ball 702 will be sandwiched between two of the metal spacers 701 and cannot move left or right. It can only make a sound as the hollow wheel 7 rotates, thereby avoiding accidental contact caused by the patient's movement.

[0031] Because the nasogastric tube is wrapped around the outer end of the pressure roller shaft 603 and pressed and fixed to the patient's philtrum by the pressure roller shaft 603, once it is pulled by an unknown force, the nasogastric tube will move and drive the pressure roller shaft 603 to rotate under the action of friction. After the pressure roller shaft 603 rotates, the hollow wheel 7 at one end will rotate accordingly. The impact ball 702 will roll inside the hollow wheel 7 and collide with the inner wall of the hollow wheel 7 and the metal partition 701 to make a sound, which serves as a warning sound. The warning sound passes through the sound-permeable mesh to make a reminder, so that abnormalities of the nasogastric tube can be detected in time, avoiding further pulling and causing it to fall out of the patient's body, greatly reducing the probability of accidental dislodgement of the nasogastric tube.

[0032] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
