Description

Technical Field

[0001] The invention relates to the technical field of drainage tubes, in particular to a suture-free fixation abdominal drainage tube. Background Art

[0002] Abdominal drainage tubes are primarily used to drain peritoneal fluid or pus. Commonly used drainage tubes are typically hollow tubes with a drainage hole at one end. One end is placed into the abdominal cavity and secured with sutures at the skin insertion point to prevent slippage or displacement. However, due to loose sutures or patient movement, sutured drainage tubes can easily become dislodged, requiring reintubation. Furthermore, suture fixation increases the workload of physicians and causes pain for patients during suture removal.

[0003] Chinese invention patent CN106512180B proposes an abdominal drainage tube comprising a guide tube made of plastic material, with open ends at both the bottom and top. A pair of annular balloons, arranged vertically along the guide tube's axial direction, are secured to the outer contour of the tube. A connecting tube, connected to the annular balloon cavities, is secured to each of the balloons. A latex airbag with an exhaust valve is secured to the other end of the connecting tube. This device, while preventing blockage, leakage, and slippage, eliminates the need for fixation when draining fluid from the abdominal cavity, is worthy of widespread application.

[0004] In the above-mentioned guide tube, the provision of the annular balloon can avoid suturing and fixation. However, in actual research, we found that it also has certain shortcomings, such as:

[0005] The diameter of the abdominal wall incision is limited, and the diameter of the above-mentioned annular balloon is relatively large even in the non-inflated / liquid state, which makes it inconvenient to enter the patient's abdominal cavity. Summary of the Invention

[0038] 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 creative efforts are within the scope of protection of the present invention.

[0039] Example 1:

[0040] See also Figure 1-Figure 3 、 Figure 7 A suture-free abdominal drainage tube comprises a tube body 1, such as Figure 1 As shown, a tube sleeve 2 is sleeved on the tube body 1, and an annular airbag 3 is fixed on the outer wall of the tube sleeve 2. The annular airbag 3 is in a straight ring shape and acts as an external barrier.

[0041] like Figure 2 As shown, the annular airbag 2 5 is connected to the tube sleeve 2 through the annular airbag 3 6 and is located below the annular airbag 1 3, acting as an inner block. The abdominal wall is located between the annular airbag 1 3 and the annular airbag 2 5. The annular airbag 1 3 and the annular airbag 2 5 clamping action can achieve stable fixation of the tube body 1, and can also effectively prevent liquid leakage.

[0042] In the present invention, the outer edge of the annular airbag 3 6 is preset as follows Figure 3 The downwardly bent shape shown in the figure can make the annular airbag 3 6 become straight and annular by inflation. The specific shape change can be referred to Figure 7 In order to further accommodate the annular airbag 2 5, a receiving slope 4 is formed on the outer wall of the bottom end of the tube sleeve 2. The annular airbag 2 5 is attached to the receiving slope 4, thereby reducing the intubation resistance and making it easier for the annular airbag 2 5 to enter the abdominal cavity.

[0043] In this embodiment, the bendable annular airbag 3 6 can enable the annular airbag 2 5 to adhere to the storage slope 4 when not inflated, reducing the intubation resistance and facilitating smooth entry into the abdominal wall incision. At the same time, after inflation, it expands into an annular structure to achieve stable fixation.

[0044] Specifically, if Figure 7 As shown, the bottom surface of the annular airbag 3 6 is provided with a plurality of folds so that the annular airbag 3 6 is in a downwardly bent state when not inflated. After inflation, the folds are flattened, so that the annular airbag 3 6 is in a straight state.

[0045] For those skilled in the art, the specific implementation method of the shape change of the annular airbag 36 can be changed according to actual needs, such as using deformation memory materials, non-uniform wall thickness, etc.

[0046] By storing the annular airbag 2 5 at the storage slope 4, the annular airbag 2 5 is cleverly "hidden", which is convenient for intubation and ensures the fixing effect. The annular airbag 2 5 of sufficient size can effectively fix and prevent leakage.

[0047] In the present invention, the annular airbag 2 5 is connected to the annular airbag 3 6 and is inflated synchronously;

[0048] In addition, an inflation method is provided. Figure 3 : A gas cabinet 7 is fixedly mounted on the outer wall of the pipe sleeve 2. An annular piston 8 is provided in the gas cabinet 7 for vertical movement. The annular piston 8 is supported by a support spring 9. The gas cabinet 7 is connected to the annular airbag 1 3 and the annular airbag 3 6 through a connecting pipe 10. Therefore, when the annular piston 8 moves downward, the gas in the gas cabinet 7 can be filled into the annular airbag 1 3, the annular airbag 2 5 and the annular airbag 3 6 through the connecting pipe 10, causing them to swell.

[0049] Specific use: intubation is performed when the tube is not inflated; inflation is performed after intubation is completed.

[0050] Example 2:

[0051] See also Figure 3-Figure 6 On the basis of the first embodiment, in this embodiment, the position of the tube sleeve 2 on the tube body 1 can be adjusted, so that the fixed position of the annular airbag can be flexibly adjusted according to the actual situation of the patient, ensuring that the drainage tube can be stably placed in the abdominal cavity of patients of different body sizes, preventing slippage, and further improving the drainage effect.

[0052] Specifically, the tube sleeve 2 is fixed on the tube body 1 by means of friction, and the fixing position of the annular airbag can be adjusted according to actual needs, thereby improving adaptability.

[0053] Furthermore, a plurality of support plates 11 that can be retracted toward the tube body 1 are evenly arranged at the top end of the tube sleeve 2, and a pressure-sensitive adhesive tape 12 is provided on the inner side of the support plates 11. By retracting the plurality of support plates 11 toward the tube body 1, the tube sleeve 2 can be firmly fixed to a designated position on the tube body 1 by utilizing the "holding" of the support plates 11 and the adhesive force of the pressure-sensitive adhesive tape 12.

[0054] like Figure 4 As shown, the outer side of the top of the support plate 11 is inclined to form an outer slope surface 13, as shown in FIG. Figure 5 As shown, a threaded barrel 14 is further provided, which is screwed onto the sleeve 2. An extrusion ring 15 is fixedly mounted on the top of the inner wall of the threaded barrel 14. The inner side of the extrusion ring 15 is inclined to form an inner slope surface 16 that matches the outer slope surface 13.

[0055] The threaded barrel 14 is screwed to move the threaded barrel 14 downward. When the threaded barrel 14 moves downward, the inner slope 16 squeezes the outer slope 13, so that the support plate 11 can be retracted toward the pipe body 1. In this embodiment, the support plate 11 and the pipe sleeve 2 can be fixedly connected, and the retraction is achieved by bending the support plate 11 itself.

[0056] In this embodiment, the support plate 11 and the pipe sleeve 2 can also be movably connected, and the folding is achieved by moving the support plate 11. Specifically, Figure 6 As shown, the bottom of the support plate 11 is fixedly connected to a slider 18 through a connecting block 17. The slider 18 is slidably installed in a slide groove 19 opened at the top of the pipe sleeve 2 and is supported by an elastic support block 20. The elastic support block 20 is elastic cotton;

[0057] When the support plate 11 is squeezed, the connecting block 17 drives the slider 18 to move, thereby causing the slider 18 to compress the elastic support block 20 until the support plate 11 hugs the tube body 1; subsequently, when the threaded barrel 14 is rotated in the opposite direction to move the threaded barrel 14 upward, the support plate 11 is reset under the action of the elastic support block 20.

[0058] In the present invention, Figure 3 As shown, when the threaded barrel 14 moves downward, its bottom end will also push the annular piston 8 downward, thereby realizing automatic inflation; therefore, in specific use, the tube sleeve 2 is first put on the tube body 1, and then the tube body 1 is inserted into the abdominal cavity through the abdominal wall incision. After insertion, the position of the tube sleeve 2 is adjusted so that the annular airbag 2 5 enters the abdominal cavity and the annular airbag 1 3 is blocked outside the incision. Then, the threaded barrel 14 is twisted to fix the position of the tube sleeve 2 and inflate the annular airbag. In this way, the position of the tube body 1 is fixed, and the effect of suture-free fixation is achieved.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
