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 mainly used to drain abdominal effusion or pus. Commonly used drainage tubes are generally hollow tubes with drainage holes at one end. One end of the tube is placed in the abdominal cavity and fixed with sutures at the point where the skin passes to prevent it from slipping or shifting. However, due to loose sutures, patient activity, etc., the sutured drainage tube can easily fall out, resulting in the need for reintubation. In addition, the suture fixation method also increases the workload of doctors and brings pain to patients when removing the sutures.

[0003] In Chinese invention patent CN106512180B, a peritoneal drainage tube is proposed, including a guide tube made of plastic material, the bottom and top of the drainage tube are both open ends, a pair of annular balloons arranged up and down along the axial direction of the guide tube are sleeved and fixed on the outer contour surface of the guide tube, a connecting tube connected to the annular balloon cavity is fixed on both annular balloons, and a latex air bag with an exhaust valve is fixed on the other end of the connecting tube. When draining the effusion in the peritoneal cavity, the present invention has the functions of preventing blockage, leakage, slippage, and fixation-free, and is worthy of popularization and application.

[0004] In the above-mentioned guide tube, the setting of the annular balloon can avoid suturing and fixation. However, in actual research, we found that it also has certain shortcomings, such as: The diameter of the abdominal wall incision is limited, and the diameter of the above-mentioned annular balloon is relatively large even when it is not inflated / liquid state, which makes it inconvenient to enter the patient's abdominal cavity.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0022] Embodiment 1: See also Figure 1-Figure 3 , Figure 7 , a suture-free abdominal drainage tube, comprising a tube body 1, such as Figure 1As 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 serves as an external stop. 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, playing the role of an inner block. The abdominal wall is located between the annular airbag 1 3 and the annular airbag 2 5. Through the clamping effect of the annular airbag 1 3 and the annular airbag 2 5, the tube body 1 can be stably fixed, and liquid leakage can also be effectively prevented.

[0023] In the present invention, the outer edge of the annular airbag 36 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 inflating. The specific shape change can be referred to Figure 7 In order to further accommodate the annular airbag 25, a receiving slope 4 is formed on the outer wall of the bottom end of the tube sleeve 2, and the annular airbag 25 is attached to the receiving slope 4, thereby reducing the intubation resistance and making it easier for the annular airbag 25 to enter the abdominal cavity.

[0024] In this embodiment, the bendable annular airbag three 6 can make the annular airbag two 5 attached 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.

[0025] 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.

[0026] 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.

[0027] By storing the annular airbag 2 5 at the storage slope 4, the annular airbag 2 5 is cleverly "hidden" to facilitate intubation, while ensuring the fixing effect. The annular airbag 2 5 of sufficient size can not only effectively fix, but also effectively prevent leakage.

[0028] In the present invention, the annular airbag 2 5 is connected to the annular airbag 3 6 and is inflated synchronously; In addition, an inflation method is provided. Figure 3A gas cabinet 7 is fixedly mounted on the outer wall of the pipe sleeve 2, and an annular piston 8 is movably arranged in the gas cabinet 7. The annular piston 8 is supported by a supporting spring 9. The gas cabinet 7 is connected with the annular airbag 1 3 and the annular airbag 3 6 through a connecting pipe 10. Therefore, by moving the annular piston 8 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, so that they swell.

[0029] Specific use: intubation is performed when the tube is not inflated; inflation is performed after intubation is completed.

[0030] Embodiment 2: See also Figure 3-Figure 6 On the basis of the first embodiment, in the present 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 to prevent slippage, thereby further improving the drainage effect.

[0031] 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.

[0032] Furthermore, a plurality of support plates 11 that can be retracted toward the tube body 1 are evenly arranged at the top of the tube sleeve 2, and a pressure-sensitive adhesive tape 12 is provided on the inner side of the support plates 11. When the plurality of support plates 11 are retracted toward the tube body 1, the tube sleeve 2 can be firmly fixed at 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.

[0033] 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, such as Figure 5 As shown, a threaded barrel 14 is also provided, which is screwed on the pipe sleeve 2, and an extrusion ring 15 is fixedly installed on the top of the inner wall of the threaded barrel 14, and the inner side of the extrusion ring 15 is inclined to form an inner slope surface 16 that matches the outer slope surface 13; The threaded barrel 14 is screwed to move 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.

[0034] In this embodiment, the support plate 11 and the pipe sleeve 2 may 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 with 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 supported by an elastic support block 20. The elastic support block 20 is elastic cotton; When the support plate 11 is squeezed, the connecting block 17 drives the slider 18 to move, and then the slider 18 compresses 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.

[0035] In the present invention, Figure 3 As shown, when the threaded tube 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 tube 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.

[0036] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
