Description

Technical Field

[0001] The present invention relates to the technical field of nasobiliary duct fixation, and in particular to a nasobiliary duct fixation device. Background Art

[0002] Endoscopic nasobiliary drainage (ENBD) is a procedure in which a 6-8Fr polyethylene catheter of about 250 cm is inserted through the duodenal papilla into the bile duct for decompression drainage based on direct retrograde cholangiopancreatography (ENCP) under duodenoscope. The purpose is to achieve decompression, jaundice reduction, and anti-inflammation through drainage, and to prevent the occurrence of pancreatitis and cholangitis after ERCP. In the care of nasobiliary drainage, the conventional fixation method uses 3M super glue to fix the nose and cheek, and then the remaining catheter is coiled and fixed to the auricle. This fixation method is more suitable for patients with normal cognition or consciousness, but it is not suitable for some patients with normal cognition or consciousness. For patients with decreased biliary function, such as those with senile dementia or those with hazy consciousness or light coma, this fixation method has a greatly increased risk of unplanned extubation; nasobiliary drainage is to insert a guide wire into the common bile duct after diagnostic retrograde cholangiopancreatography, and then place a drainage tube with holes at the top and side wall into the biliary system through the guide wire. After the drainage tube enters the predetermined position, the endoscope is withdrawn and the guide wire is finally pulled out; a nasogastric tube is inserted from the nasal cavity into the pharynx and then led out from the oral cavity, and the drainage tube is inserted into the nasogastric tube and then led out from the nasal cavity; existing nasobiliary fixation mostly involves sticking tape to the nose to fix the nasobiliary duct, but this fixation method is prone to produce nasobiliary problems over time There is a great safety hazard in the event of detachment, because people have designed a device that can fix the nasobiliary duct to ensure the stability of the nasobiliary duct. For example, a technical solution is disclosed in Patent No.: CN202020761047.0. The solution proposes that for the comfort of the nasobiliary duct, the nasobiliary duct is fixed with various parts, and then fixed behind the ear. The parts are composed of support plates, threaded rods and other structures. However, there are still some problems when using the device. Generally, people's nasobiliary duct is led out of the nasal cavity, and then the nasobiliary duct is bent and fixed by the side of the mouth. This technical solution also continues this fixation method. The feature of the present invention is that it is easy to adjust. However, in actual use, since the nasobiliary duct is located in the mouth, it causes patients to feel very uncomfortable when eating or talking. In addition, the technical solution uses a support plate, a threaded rod and other mechanisms. On the one hand, the structure is relatively complex, and its structure occupies a large space. In addition, it is located at the nose. Patients generally turn their heads when lying down. However, the space occupied by the technical solution will cause the patient to be unable to complete the action when turning his head, resulting in discomfort to the patient, thereby reducing the practicality and convenience of the device. In addition, putting pressure on the patient's nose for a long time will cause the patient's nose to feel very uncomfortable.

[0003] Based on this, the present invention designs a nasobiliary duct fixation device to solve the above problems. Summary of the Invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] See also Figures 1-6 , the present invention provides a technical solution:

[0027] A nasobiliary duct fixation device includes a fixing plate 1, a slide plate 2 is slidably connected to the fixing plate 1, a self-locking mechanism 3 is provided in the fixing plate 1, a nose patch 8 is rotatably connected to one end of the fixing plate 1, an angle adjustment mechanism 10 is provided on the nose patch 8, a height adjustment mechanism 14 is provided on the angle adjustment mechanism 10, a clamping mechanism 20 is provided on the upper side of the height adjustment mechanism 14, a support plate 25 is fixedly connected to the angle adjustment mechanism 10, the support plate 25 is slidably connected to the nose patch 8, an anti-folding mechanism 26 is provided on the support plate 25, a universal ball 30 is rotatably connected to both the fixing plate 1 and the slide plate 2, another height adjustment mechanism 14 is fixedly connected to the universal ball 30, another clamping mechanism 20 is installed on one end of the other height adjustment mechanism 14, and a fixing mechanism 31 is installed on one end of the slide plate 2;

[0028] During operation, the parts in the fixing mechanism 31 are pulled to fix the device on the human head, and then the length of the device is adjusted so that the slide plate 2 slides in the fixing plate 1, and the universal ball 30 is rotated. At this time, the fixing plate 1 and the slide plate 2 in the device are located at the bridge of the human nose, and the nose patch 8 in the device is located at the nose wing of the human body. At this time, the device adjustment is completed, and then the multiple height adjustment mechanisms 14 are pulled to make the parts in the height adjustment mechanism 14 cooperate with each other, thereby changing the position of the clamping mechanism 20. When the position adjustment of the clamping mechanism 20 is completed, the clamping mechanism 20 is controlled to open the clamping mechanism 20, and then the nasobiliary duct is placed in the clamping mechanism 20. Then, by adjusting the angle adjustment mechanism 10, the position of one of the clamping mechanisms 20 is changed, and the nasal catheter is placed and folded upward and placed in the anti-folding mechanism 26, so that the device fixes the nasal catheter;

[0029] The present invention can effectively fix the fixing plate 1 and the slide plate 2 in the device to the head and the bridge of the nose of the human body through the fixing mechanism 31 in the device, so that the device is more stable and more fit when fixed, avoiding the situation that the device occupies a large space when in use, thereby causing the patient to be unable to move the head. After the device is fixed, the anti-folding mechanism 26 can be used to effectively fold the nasal bile duct upward, so that the nasal bile duct is away from the mouth of the human body, thereby avoiding the situation that the nasal bile duct is located in the mouth of the human body when people use the device, which causes the patient to be restricted in speaking and eating, further improving the practicality of the device. The mutual cooperation between the fixing plate 1 and the slide plate 2 in the device allows the device to be adjusted according to the human body when in use. The device can be adjusted to the size of the head and the bridge of the nose, making the device more convenient and stable when used. The angle adjustment mechanism 14 in the device can adapt the device to different heights and angles when in use, making it more convenient for patients to use, avoiding the device being unstable when fixing the nasobiliary duct due to the fixed angle during use, thereby causing certain limitations. The various parts in the device cooperate with each other, making the device more convenient to use and the structure simpler. When worn, the patient can turn his head left and right without affecting the fixation of the nasobiliary duct, and the device occupies less space and is more practical, further ensuring the fixation of the nasobiliary duct and avoiding affecting other operations during fixation, thereby further improving its practicality.

[0030] As a further solution of the present invention, the self-locking mechanism 3 includes a first spring 4, a gasket 5, a limiting column 6 and a limiting groove 7. Two first springs 4 are fixedly connected to the fixed plate 1, one end of the first spring 4 is fixedly connected to the gasket 5, and the limiting column 6 is fixedly connected to the gasket 5. One end of the limiting column 6 is arc-shaped. A plurality of limiting grooves 7 are provided on both sides of the slide plate 2, and the limiting column 6 is slidably connected to the limiting groove 7;

[0031] During operation, when adjusting the length of the device, push the fixed plate 1 to move the fixed plate 1 on the slide plate 2. When the fixed plate 1 moves, the fixed plate 1 moves on the slide plate 2, thereby causing the self-locking mechanism 3 to work. When the self-locking mechanism 3 on the fixed plate 1 works, the first spring 4 in the self-locking mechanism 3 is squeezed, thereby causing the limiting column 6 to slide in the limiting groove 7, and then causing the limiting column 6 to move in the multiple limiting grooves 7 respectively, thereby fixing the fixed plate 1 and the slide plate 2. When the distance between the slide plate 2 and the fixed plate 1 is adjusted, the device can work normally.

[0032] The present invention changes the length of the device by moving the slide plate 2 and the fixed plate 1 in the device, making the device more convenient to use and adaptable to different patients. The self-locking mechanism 3 can effectively fix the slide plate 2 and the fixed plate 1 during use, thereby avoiding the device from being unable to be fixed when being adjusted. The self-locking mechanism 3 is located on the inner side of the fixed plate 1, avoiding the device from occupying a large space during use, thereby affecting the use of the device.

[0033] As a further embodiment of the present invention, the fixing plate 1 and the slide plate 2 are arc-shaped, the bottom surfaces of the fixing plate 1 and the slide plate 2 are V-shaped, the nose patch 8 is V-shaped, and two connecting seats 9 are provided on the nose patch 8, and the connecting seats 9 are rotatably connected to the fixing plate 1;

[0034] During operation, since the fixing plate 1 and the slide plate 2 are both V-shaped, the fixing plate 1 and the slide plate 2 can fit the nose bridge of the human body more closely when in use, making the device more comfortable to use and more convenient to wear.

[0035] As a further embodiment of the present invention, the angle adjustment mechanism 10 includes a slide 11, a slider 12, and a first screw 13. The nose plate 8 is provided with a slide 11, the slide 12 is slidably connected to the slide 11, and the first screw 13 is threadedly connected to the slider 12. The bottom surface of the first screw 13 is movably connected to the nose plate 8.

[0036] During operation, the slider 12 is pulled to slide in the slide groove 11. When the slider 12 moves to a certain position, the first screw rod 13 is rotated to move the first screw rod 13 on the slider 12. When the first screw rod 13 moves to a certain position, the first screw rod 13 can be effectively squeezed on the nose plate 8, thereby effectively fixing the device slider 12.

[0037] The present invention makes the angle of the device change according to people's needs when using the device by cooperating with each other through the various parts in the angle adjustment mechanism 10, thereby making the device more convenient to use and avoiding the problem that the angle of the device is fixed, which affects the use of the device and reduces the use effect of the device.

[0038] As a further embodiment of the present invention, the height adjustment mechanism 14 includes a fixed housing 15, a second spring 16, an adjusting rod 17, a second screw rod 18 and a nut 19. The fixed housing 15 is fixedly connected to the slider 12, the second spring 16 is fixedly connected to the fixed housing 15, one end of the second spring 16 is fixedly connected to the adjusting rod 17, the adjusting rod 17 is slidably connected to the fixed housing 15, the second screw rod 18 is fixedly connected to the adjusting rod 17, and the nut 19 is threadedly connected to the second screw rod 18;

[0039] During operation, the nut 19 is rotated to move the nut 19 on the second screw rod 18. When the second screw rod 18 moves away from the fixed housing 15, the elastic force of the second spring 16 bounces the adjustment rod 17, thereby moving the clamping mechanism 20 upward. When the adjustment rod 17 moves to a certain position, the nut 19 is rotated again to bring the nut 19 closer to the fixed housing 15, thereby fixing the adjustment rod 17. At this time, the height adjustment of the equipment is completed;

[0040] The present invention adjusts the parts of the mechanism to cooperate with each other, so that the height of the nasobiliary duct can be changed according to people's needs when the device is in use, so that the nasobiliary duct can be drained at a certain slope, thereby further improving the practicality and convenience of the device.

[0041] As a further embodiment of the present invention, the clamping mechanism 20 includes a rotating column 21, a clamping plate 22, a torsion spring 23, and a protective sleeve 24. The adjusting rod 17 is rotatably connected to the rotating column 21, and the rotating column 21 is rotatably connected to two clamping plates 22. The rotating column 21 is sleeved with a torsion spring 23, which is located between the two clamping plates 22. A protective sleeve 24 is provided on the inner side of the clamping plate 22, and the protective sleeve 24 uses a flexible rubber layer.

[0042] During operation, the two clamping plates 22 are rotated to move the two clamping plates 22 away from each other. When the two clamping plates 22 move away from each other, the torsion spring 23 provided between the two clamping plates 22 is compressed. At this time, the nasobiliary duct can be placed in the protective cover 24 between the two clamping plates 22. Then, the clamping plates 22 are released to allow the torsion spring 23 to rebound. When the torsion spring 23 rebounds, the nasobiliary duct is fixed.

[0043] The present invention enables the various parts in the clamping mechanism 20 to cooperate with each other, so that the device can effectively fix materials of different diameters when in use, and the protective sleeve 24 in the device can effectively protect the nasobiliary duct from being squeezed and deformed, making the device safer and more convenient when in use.

[0044] As a further embodiment of the present invention, the anti-folding mechanism 26 includes an elastic plate 27, a third spring 28 and a slot 29. The elastic plate 27 is fixedly connected to the support plate 25. The elastic plate 27 is arc-shaped. The third spring 28 is fixedly connected between the elastic plate 27 and the support plate 25. The elastic plate 27 is provided with a slot 29.

[0045] During operation, after the nasobiliary duct is led out of the nasal cavity, the nasal catheter is folded upward. At this time, the nasobiliary duct is located in the card slot 29. Since the elastic plate 27 is arc-shaped, when the nasobiliary duct is folded, the nasobiliary duct can be folded following the shape of the elastic plate 27, thereby avoiding the nasobiliary duct from being squeezed and deformed. When the nasobiliary duct is subjected to force, the elastic plate 27 is pressed down, and then the third spring 28 is lowered, so that the nasobiliary duct is subjected to force and changes, further ensuring the use of the nasobiliary duct, avoiding the device from folding during use, thereby affecting the use of the device and causing it to be unsafe for patients to use.

[0046] As a further embodiment of the present invention, the fixing mechanism 31 includes a bonding plate 32 and a headband 33. The bonding plate 32 is fixedly connected to the skateboard 2. Two headbands 33 are fixedly connected to the bonding plate 32. The surface of the headband 33 is provided with a flexible rubber skin-friendly layer.

[0047] During operation, the two headbands 33 are pulled to stretch the two headbands 33, and then the headbands 33 are fixed to the human head. When the two headbands 33 are fixed to the human head, the fastening force of the headbands 33 can effectively fix the bonding plate 32, so that the bonding plate 32 is fixed to the human head, thereby ensuring the stability between the fixing plate 1 and the slide plate 2, and further improving the practicality and convenience of the equipment.
