[0031] 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.

[0032] Please see Figures 1-6 As shown, this embodiment is an abdominal drainage tube fixing device, including a base plate 1, a connecting structure 2 fixedly connected to the upper end face of the base plate 1, an adjusting structure 3 symmetrically fixedly connected to the lower end face of the base plate 1, a clamping structure 4 slidably connected to the lower end face of the inner cavity of the adjusting structure 3, a one-way blocking structure 5 fixedly connected to the middle of the inner cavity of the connecting structure 2, and a winding structure 6 fixedly connected to both the left and right end faces of the base plate 1. A connecting belt 7 is provided in the inner cavity of the two winding structures 6. A snap-fit ​​structure 8 is fixedly connected to the left end face of the left connecting belt 7, and a fixing structure 9 is fixedly connected to the right end face of the right connecting belt 7.

[0033] Furthermore, the connecting structure 2 includes a threaded tube 21 fixedly connected to the middle of the upper end face of the base plate 1. An adjusting sleeve 22 is threadedly connected to the outer surface of the threaded tube 21. An inner connecting tube 23 is fixedly connected to the upper end face of the inner cavity of the threaded tube 21. Gaskets 24 are uniformly fixedly connected to the upper end face of the threaded tube 21 with the center of the threaded tube 21 as the center point. A compression ring is fixedly connected to the upper part of the inner side wall of the adjusting sleeve 22. A one-way barrier structure 5 is fixedly connected to the middle of the inner cavity of the threaded tube 21. After the external drainage tube is inserted into the outer surface of the inner connecting tube 23, the adjusting sleeve 22 is rotated. The compression ring fixedly connected to the inner cavity of the adjusting sleeve 22 causes the gasket 24 to bend towards the side closer to the inner connecting tube 23. The inner connecting tube 23 and the gasket 24 squeeze each other to compress and fix the external drainage tube. Since the external drainage tube is inserted into the outer surface of the inner connecting tube 23, it can effectively prevent liquid leakage during drainage and ensure the normal progress of the drainage process.

[0034] Furthermore, the adjustment structure 3 includes an adjustment frame 31 symmetrically fixedly connected to the lower end face of the base plate 1. A sliding rod 32 is fixedly connected to the inner cavity of the adjustment frame 31. A spring 33 is movably sleeved in the middle of the outer surface of the sliding rod 32. A clamping structure 4 is symmetrically slidably connected to the inner cavity of the adjustment frame 31. The spring 33 is located between the two opposing clamping structures 4. Through the adjustment structure 3 on the base plate 1, the clamping structure 4 is installed and placed during use, and the distance between the two clamping structures 4 is adjusted by the extension and retraction of the spring 33.

[0035] Furthermore, the clamping structure 4 includes sliders 41 symmetrically slidably connected to the inner cavity of the adjusting frame 31. A spring 33 is driven between the two sliders 41. A fixing box 42 is fixedly connected between two adjacent sliders 41. A groove is opened on each adjacent side of the fixing box 42. An elastic fixing band 43 is fixedly connected to the inner cavity of the groove. A medicine outlet is evenly opened on the lower end face of the fixing box 42. By pulling the fixing box 42 relative to each other, healing-promoting powder can be conveniently placed in the inner cavity of the fixing box 42. And by the extension and contraction of the spring 33, the elastic fixing band 43 is attached to and fixed to the drainage tube on the patient's abdominal cavity, thereby fixing the drainage tube. At the same time, the placement of the powder may help the patient's wound healing.

[0036] Furthermore, the one-way barrier structure 5 includes a mounting rod 51 fixedly connected to the middle of the inner cavity of the threaded tube 21. The front and rear end faces of the mounting rod 51 are respectively hinged to barrier plates 52. The inner cavity of the threaded tube 21 is fixedly connected to the lower end face of the barrier plates 52. Through the one-way barrier structure 5 on the base plate 1, when the ascites is discharged during use, the pressure causes the two barrier plates 52 to rotate relative to each other, thereby making the inner cavity of the threaded tube 21 connected. When the effusion flows back, the barrier plates 52 rotate in the opposite direction due to the push of the effusion. At this time, due to the limitation of the limit rod 53, the inner cavity of the threaded tube 21 is sealed by the barrier plates 52, so that the effusion can only flow in one direction in the inner cavity of the connecting structure 2, avoiding secondary damage to the patient caused by the effusion backflow.

[0037] Furthermore, the winding structure 6 includes winding frames 61 fixedly connected to the left and right sides of the base plate 1 respectively. A connecting shaft 62 is fixedly connected to the center of the inner cavity of the winding frame 61. A torsion spring 63 is movably sleeved on the center of the outer surface of the connecting shaft 62. One end of the torsion spring 63 is fixedly connected to the connecting shaft 62. A connecting belt 7 is movably sleeved on the outer surface of the torsion spring 63. The end of the torsion spring 63 away from the connecting shaft 62 is fixedly connected to the connecting belt 7. Through the winding structure 6 on the base plate 1, the connecting belt 7 is installed and placed during use. Then, when the device is placed, the torsion spring 63 pushes the winding roller 71 to wind the fixed belt 72 into the inner cavity of the winding frame 61.

[0038] Furthermore, the connecting belt 7 includes a take-up roller 71 that is movably sleeved on the outer surface of the torsion spring 63. The end of the torsion spring 63 away from the connecting shaft 62 is fixedly connected to the take-up roller 71. The outer surface of the take-up roller 71 is connected to a fixed belt 72. The ends of the two fixed belts 72 away from the take-up roller 71 are respectively fixedly connected to a snap-fit ​​structure 9.

[0039] Furthermore, the snap-fit ​​structure 8 includes a mounting plate 81 fixedly connected to the left end face of the left fixed waist belt 72, a connecting block 82 fixedly connected to the middle of the left end face of the mounting plate 81, and a limit plate 83 fixedly connected to the left end of the connecting block 82.

[0040] Furthermore, the fixing structure 9 includes a mounting plate 91 fixedly connected to the right end face of the right-side fixing belt 72. A fixing block 92 is symmetrically fixedly connected to the right end face of the mounting plate 91. Telescopic structures 93 are symmetrically opened on both the upper and lower end faces of the fixing block 92. A limiting block 94 is fixedly connected to the side of the telescopic structure 93 away from the fixing block 92. The gap between the limiting block 94 and the limiting plate 83 and the mounting plate 81 are matched.

[0041] Furthermore, the telescopic structure 93 includes telescopic sleeves 931 symmetrically fixedly connected to the upper and lower end faces of the fixed block 92. A telescopic rod 932 is slidably connected to the inner cavity of the telescopic sleeve 931. A spring is connected between the telescopic rod 932 and the telescopic sleeve 931. A limit block 94 is fixedly connected to the end of the telescopic rod 932 away from the telescopic sleeve 931. Through the cooperation of the snap-fit ​​structure 8 and the fixed structure 9, as well as the function of the fixed waist belt 72, torsion spring 63 and other structures, the fixed waist belt 72 can be tightened and fitted to the patient's waist and abdomen, so as to achieve stable fixation of the entire device on the patient's body, prevent the device from loosening or shifting, and ensure the stability of the drainage tube fixation.

[0042] Working principle: During operation, pulling the fixation box 42 relative to each other causes the slider 41 to slide relative to each other, thus extending the spring 33. At this time, the person places the healing-promoting powder into the inner cavity of the fixation box 42. Then, the base plate 1 is placed against the corresponding position on the patient. At this time, the fixation box 42 is released, causing the spring 33 to contract. Therefore, the two fixation boxes 42 on both sides move closer together, thereby allowing the elastic fixation band 43 to adhere to and fix the drainage tube on the patient's abdominal cavity.

[0043] At this time, the personnel pull the locking structure 8 and the fixing structure 9 respectively, causing the waist belts 72 fixed on both sides of the base plate 1 to extend. This brings the fixing structure 9 and the locking structure 8 closer together. At this time, due to the force of the connecting block 82, the limiting block 94 moves away from each other. Therefore, the telescopic rod 932 retracts into the inner cavity of the telescopic sleeve 931, causing the fixing block 92 to fit against the mounting plate 81. At this time, the spring in the inner cavity of the telescopic sleeve 931 extends, causing the telescopic rods 932 to move closer together, which in turn brings the limiting blocks 94 closer together. Thus, the limiting blocks 94 are locked between the mounting plate 81 and the limiting plate 83. Since the outer surface of the fixing waist belt 72 is fitted with a torsion spring 63, when the fixing waist belt 72 extends, the torsion spring 63 provides a force in the opposite direction to the winding roller 71, making the fixing waist belt 72 taut and fit against the patient's waist and abdomen.

[0044] When it is necessary to connect the external drainage tube to the connecting structure 2, so that the external drainage tube is inserted into the outer surface of the inner connecting tube 23, the adjusting sleeve 22 is rotated to move the adjusting sleeve 22 upward. At this time, since the inner cavity of the adjusting sleeve 22 is fixedly connected to the compression ring, the gasket 24 is bent towards the side closer to the inner connecting tube 23. At this time, the external drainage tube is squeezed and fixed by the mutual compression between the inner connecting tube 23 and the gasket 24. At the same time, since the external drainage tube is inserted into the outer surface of the inner connecting tube 23, leakage of liquid is prevented during drainage.
