Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a abdominal drainage tube fixing device. Background Art

[0002] Peritoneal drainage tube is a commonly used device after surgical operation, which is common in abdominal surgical operation. Peritoneal drainage tube can drain the body's accumulated blood, accumulated gas, pus and blood, and observe the quality, quantity and color of the drainage fluid, so as to judge whether the patient has heavy bleeding and infection after the operation. When the patient is implanted with a peritoneal drainage tube clinically, after the drainage tube is placed in the patient's drainage site, sutures are mostly used to fix the drainage tube to the patient's skin. Some patients with more complicated conditions need to keep the peritoneal drainage tube for a long time after the operation. The peritoneal drainage tube will cause friction with the patient's skin during use, which may cause redness, swelling or even damage to the patient's skin. In addition, the long-term contact and friction between the peritoneal drainage tube and the patient's skin may cause continuous damage to the drainage port or even inflammatory reaction, forming a chronic sinus tract.

[0003] After searching, a Chinese invention patent disclosed a publication number of CN117861043A, which is an auxiliary fixing device for abdominal drainage tube. It relates to the field of medical device technology and is used to fix the abdominal drainage tube. It includes a bandage, a fixing component is arranged above the middle of the bandage, an adsorption and fastening component is arranged inside the fixing component, and a rotating component is arranged above the fixing component; the abdominal drainage tube is fixed to the middle of the patient's drainage port through the extrusion parts in a ring array in the fixing component and the setting of the bandage, so as to avoid the abdominal drainage tube from being in contact with one side of the drainage port for a long time during the retention period in the patient's body, and then the mutual friction between the two occurs, thereby avoiding the patient's skin from becoming red and swollen or even damaged, reducing the inflammatory reaction of the patient's skin and the chronic sinus tract formed due to continuous wear of the drainage port, and further, avoiding the infection or migratory abscess caused by the abdominal drainage tube pressing the local tissue of the patient's drainage port too tightly, causing local pain in the patient's drainage port.

[0004] The existing abdominal drainage tube is not firmly fixed due to the simple connection method. At the same time, the length of the previous fixing device is fixed, which causes the problem that the tube cannot be well adapted to the body contours of different patients in actual use.

[0033] Furthermore, the connection structure 2 includes a threaded tube 21 fixedly connected to the middle part of the upper end surface of the bottom 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 surface of the inner cavity of the threaded tube 21, a gasket 24 is evenly fixedly connected to the upper end surface of the threaded tube 21 with the center of the threaded tube 21 as the center point, an extrusion ring is fixedly connected to the upper part of the inner cavity side wall of the adjusting sleeve 22, and a one-way barrier structure 5 is fixedly connected to the middle part of the inner cavity of the threaded tube 21. By inserting the external drainage tube into the outer surface of the inner connecting tube 23 and then rotating the adjusting sleeve 22, the extrusion ring fixedly connected to the inner cavity of the adjusting sleeve 22 causes the gasket 24 to bend toward the side close to the inner connecting tube 23. The inner connecting tube 23 and the gasket 24 squeeze each other to squeeze and fix the external drainage tube, and since the external drainage tube is inserted into the outer surface of the inner connecting tube 23, liquid leakage during drainage can be effectively avoided, thereby ensuring 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 surface 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, and a clamping structure 4 is symmetrically slidably connected to the inner cavity of the adjustment frame 31, and the spring 33 is located between two relatively clamping structures 4. The clamping structure 4 is installed and placed through the adjustment structure 3 on the base plate 1 during use, and then the distance between the clamping structures 4 on both sides is adjusted through the expansion and contraction of the spring 33, so that the device can adapt to abdominal drainage tubes of different sizes.

[0035] Furthermore, the clamping structure 4 includes a slider 41 symmetrically slidably connected to the inner cavity of the adjustment frame 31, a spring 33 is transmission-connected between the two sliders 41, a fixing box 42 is fixedly connected between the two adjacent sliders 41, adjacent sides of the fixing box 42 are respectively provided with grooves, an elastic fixing belt 43 is fixedly connected to the inner cavity of the groove, and a medicine outlet is evenly provided on the lower end surface of the fixing box 42. By relatively pulling the fixing box 42, it is convenient to place healing powder in the inner cavity of the fixing box 42, and through the expansion and contraction of the spring 33, the elastic fixing belt 43 and the drainage tube on the patient's abdominal cavity are attached to and fixed to each other, thereby achieving fixation of the drainage tube.

The inner cavity of the threaded tube 21 is located at the lower end surface of the barrier plate 52 and is respectively fixedly connected with a limiting rod 53. Through the one-way barrier structure 5 on the bottom plate 1, when ascites is discharged during use, the barrier plates 52 on both sides rotate relative to each other due to the extrusion pressure, so that the inner cavity of the threaded tube 21 is connected. When the effusion refluxes, the barrier plate 52 rotates in the opposite direction due to the push of the effusion. At this time, due to the limitation of the limiting rod 53, the inner cavity of the threaded tube 21 is sealed by the barrier plate 52, so that the effusion can only flow in one direction in the inner cavity of the connecting structure 2, thereby avoiding the reflux of the effusion and causing secondary damage to the patient.

[0037] Furthermore, the winding structure 6 includes a winding frame 61 fixedly connected to the left and right sides of the base plate 1 respectively, a connecting shaft 62 is fixedly connected to the middle of the inner cavity of the winding frame 61, a torsion spring 63 is movably sleeved on the middle 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, and one 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, and then when the device is placed, the torsion spring 63 pushes the winding roller 71 to roll up the fixed belt 72 in the inner cavity of the winding frame 61.

[0038] Furthermore, the connecting belt 7 includes a winding roller 71 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 winding roller 71, the outer surface of the winding roller 71 is transmission-connected with a fixed belt 72, and the ends of the two fixed belts 72 away from the winding roller 71 are respectively fixedly connected with a clamping structure fixing structure 9.

[0039] Furthermore, the clamping structure 8 includes a mounting plate 81 fixedly connected to the left end surface of the left fixed waist belt 72, a connecting block 82 is fixedly connected to the middle of the left end surface of the mounting plate 81, and a limiting plate 83 is fixedly connected to the left end of the connecting block 82.

[0040] Furthermore, the fixed structure 9 includes a mounting plate 91 fixedly connected to the right end face of the right fixed waist 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 provided on 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, and the gap sizes between the limiting block 94, the limiting plate 83 and the mounting plate 1 81 match each other.

[0041] Furthermore, the telescopic structure 93 includes a telescopic sleeve 931 symmetrically fixedly connected to the upper and lower end surfaces of the fixed block 92, a telescopic rod 932 is slidably connected to the inner cavity of the telescopic sleeve 931, and a tension spring is transmission-connected between the telescopic rod 932 and the telescopic sleeve 931, and one end of the telescopic rod 932 away from the telescopic sleeve 931 is fixedly connected to the limiting block 94. Through the cooperation of the clamping structure 8 and the fixed structure 9 and the action of the fixed belt 72, the torsion spring 63 and other structures, the fixed belt 72 can be tightened and fit to the patient's waist and abdomen, so that the overall device can be firmly fixed on the patient's body, the device can be prevented from loosening or shifting, and the stability of the drainage tube fixation can be ensured.

[0042] Working principle: When working, the fixing box 42 is pulled relatively to make the slider 41 slide relatively, so the spring 33 is extended. At this time, the personnel will place the medicine powder that can promote healing in the inner cavity of the fixing box 42. At this time, the bottom plate 1 is attached to the corresponding position of the patient. At this time, the fixing box 42 is released to make the spring 33 contract, so that the fixing boxes 42 on both sides are close to each other, and then the elastic fixing belt 43 and the drainage tube on the patient's abdominal cavity are attached to each other and fixed.

[0043] At this time, the personnel pull the clamping structure 8 and the fixing structure 9 respectively, so that the fixed belts 72 on the left and right sides of the bottom plate 1 are extended, so that the fixing structure 9 and the clamping structure 8 are close to each other. At this time, the limit block 94 is relatively far away from the limit block 94 due to the force of the connecting block 82, so the telescopic rod 932 shrinks to the inner cavity of the telescopic sleeve 931, so that the fixed block 92 and the mounting plate 1 81 fit each other. At this time, the inner cavity spring of the telescopic sleeve 931 is extended, so the telescopic rods 932 are close to each other, and then the limit blocks 94 are close to each other, so that the limit blocks 94 are clamped between the mounting plate 1 81 and the limit plate 83. Since the outer surface of the fixed belt 72 is sleeved with a torsion spring 63, when the fixed belt 72 is extended, the torsion spring 63 provides a force in the opposite direction to the winding roller 71, so that the fixed belt 72 is tightened and fits 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 internal 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 with an extrusion ring, the gasket 24 is bent toward the side close to the internal connecting tube 23. At this time, the external drainage tube is squeezed and fixed by the mutual extrusion between the internal connecting tube 23 and the gasket 24. At the same time, since the external drainage tube is inserted into the outer surface of the internal connecting tube 23, liquid leakage during drainage is avoided.
