The fixing belt 41 comprises a first fixing belt 411 connected with the left side of the bottom plate and a second fixing belt 412 connected with the right side of the bottom plate.

[0033] In specific implementation, one side of the first fixing belt and the second fixing belt facing the base annular plate is provided with a first magic tape belt, one side of the first magic tape belt facing the base annular plate is a thorn side, one side of the first fixing belt or the second fixing belt away from the base annular plate is provided with a second magic tape belt 7, and one side of the second magic tape belt away from the fixing belt is a wool side. The fixing belt is fixed by bonding the wool side and the thorn side after being wound around the waist and abdomen.

[0034] In specific implementation, the first fixing belt and the second fixing belt can be made of elastic cloth, and the bottom plate is made of silica gel material, which can better adhere to the human abdomen by using the deformability. The first fixing belt or the second fixing belt can be connected by sewing or hot melting, and more specifically, the base limiting ring has a certain height and can be made of hard rubber with a certain deformation ability to adapt to the deformation of the bottom plate; the base limiting ring plate is connected with the bottom plate by hot melting;

[0035] The protective cover is made of hard plastic, preferably transparent plastic, to facilitate observation of the puncture site within the protective cover.

[0036] In one embodiment, the fixing block and the fixing ring plate are integrally formed with the flow guide tube, or the fixing block and the fixing ring plate are made of plastic, and the fixing block is connected to the flow guide tube by heat welding.

[0037] In the specific implementation of the embodiment, the first fixing belt and the second fixing belt are first wrapped around the waist and abdomen of the patient, with the through hole 443 facing the puncture site, so that the puncture site is located in the middle of the through hole. Then, the first magic tape and the second magic tape are butted and adhered. During the butting and adhering process, the tightness of the first fixing belt and the second fixing belt is appropriately adjusted to make the bottom plate conform to the human abdomen. In specific use, to further increase the stability of the bottom plate, medical double-sided tape can be used to fix the bottom surface of the bottom plate. After puncturing the abdomen and inserting the drainage tube, the tube opening of the drainage tube near the fixing block is connected to the abdominal cavity environment through the puncture site. The puncture site is covered with a dressing, which is fixed with tape, and the other end of the drainage tube is connected to the drainage bottle. Then, the through hole 422 is passed through the flow guide tube between the fixing block and the human body, so that the flow guide tube is located in the through hole of the protective cover body. Then, the protective cover shell is adjusted and rotated to make the third screw and the fourth screw engage, so that the protective cover shell is fixedly installed on the bottom plate. Then, the fixing block is pulled to make the limiting guide plate 61 of the fixing ring plate 6 inserted into the groove 421. In specific implementation, the depth of the groove is 2-3 cm. Then, the fixing ring plate is rotated to make the first screw and the second screw engage, so that the fixing ring plate moves towards the protective cover shell, and the fixing block is pulled towards the protective cover shell. In this way, part of the flow guide tube can be fixed on the protective cover shell. Generally, the flow guide tube between the puncture site and the drainage bottle has sufficient length, so that the rotation of the fixing ring plate does not cause the tube opening connected to the drainage bottle to be pulled, which does not cause the drainage tube to fall off the drainage bottle. In this way, the protective cover shell can be covered on the puncture site to protect the puncture site, and the drainage tube near the puncture site located in the protective cover shell can be prevented from being pulled or scratched. Even if the drainage tube outside the protective cover shell is pulled or scratched, since part of the drainage tube near the puncture site is fixed on the protective cover shell by the fixing ring plate, the risk of the drainage tube near the puncture site in the protective cover shell being shaken or pulled out is also avoided.

[0038] As Figure 5As shown, the fixed block 5 can also be movably connected to the flow guide pipe by another embodiment, and more specifically, the flow guide pipe is provided with a fixed section, the fixed section is integrally provided with a fixed layer 7 outside the flow guide pipe, the fixed layer is provided with a fifth thread, and the hollow cavity wall of the fixed block is provided with a sixth thread engaged with the fifth thread, and more specifically, the outer diameter of the fixed section is smaller than the minimum diameter of the hole, so that the fixed section partially penetrates the hole, so that when the fixed block is movably connected to the flow guide pipe, it is specifically applied, as above, after the puncture is completed, the position of the fixed block on the fixed layer is adjusted, so that the hole 422 penetrates the flow guide pipe between the fixed block and the human body, so that the flow guide pipe is located in the through hole of the protective cover body, then the protective cover shell is adjusted, and the protective cover shell is rotated to make the third thread and the fourth thread engaged, so that the protective cover shell is fixedly installed on the bottom plate, then the fixed block is rotated, the position of the fixed block is adjusted, so that the limiting guide plate 61 of the fixed ring plate 6 is inserted into the groove 421, then the fixed ring plate is rotated, so that the first thread and the second thread are engaged, so that the fixed ring plate continuously moves towards the protective cover shell, and the fixed block is pulled towards the protective cover shell, so that part of the flow guide pipe can be fixed on the protective cover shell. Compared with the fixed block fixedly connected to the flow guide pipe, the fixed block movably connected to the flow guide pipe can make the flow guide pipe between the fixed block and the puncture port more smoothly penetrate from the gap to the through hole, and by moving the fixed block, the length of the flow guide pipe entering the protective cover shell when the fixed ring plate moves close to the puncture port can be reduced, avoiding the bending thereof. In actual application, when the fixed ring plate moves in the direction close to the puncture port, the distance of its movement does not exceed the depth of the groove, and this length will not cause the flow guide pipe to bend.

[0039] Embodiment 2: Referring to Figure 1 and Figure 8 The bottom plate 44 comprises a separable first bottom plate 441 and a second bottom plate 442, the first bottom plate 441 is provided with a first base arc-shaped ring 431, and the second bottom plate 442 is provided with a second base arc-shaped plate 432, and the first base arc-shaped plate 431 and the second base arc-shaped plate 432 are combined to form a base annular plate 43.

[0040] Compared with embodiment 1, this embodiment is more convenient to use, and it can fix the fixed ring plate on the protective cover body after puncturing the drainage tube, thereby increasing the protection thereof.

[0041] In specific implementation, the first bottom plate 441 is provided with a third magic tape 4411, the third magic tape is provided with a magic tape belt 4412, the second bottom plate is provided with a fourth magic tape 4421 matched and bonded with the magic tape belt 4412, and the combination and fixation of the first bottom plate and the second bottom plate can be realized by the cooperation of the magic tape belt and the fourth magic tape.

[0042] In this embodiment, it can be applied to perform a puncture first. In specific application, after puncturing the abdomen, a drainage tube is inserted. The opening of the drainage tube near the fixing block is connected to the abdominal cavity environment from the puncture site. The puncture site is covered with a dressing, which is fixed with adhesive tape. The other end of the drainage tube is connected to the drainage bottle. Then, after the first and second fixing straps are passed through the patient's back, the length of the base plate that fits against the skin is roughly determined in advance. The first and second Velcro are first aligned and bonded together, so that the first and second base plates are aligned, and the drainage tube is located in the through hole. Then, the Velcro tape and the fourth Velcro are bonded and fixed. At this time, the opposing surfaces of the first and second base plates, the first base arc plate 431 and the second base arc plate 432 are attached. Then, as in embodiment 1, the protective cover is fixed to the base ring plate in sequence, and the fixing ring plate is connected to the fixing block and the drainage tube is fixed to the protective cover.

[0043] Example 3: Reference Figure 1 and Figure 8 The illustrated abdominal drainage device, compared to embodiments 1 and 2, features a stopper 3 comprising a stopper body 31 adapted to the neck diameter of the bottle neck 21. The upper part of the stopper body 31 has a protrusion 32 with a notch 321 extending upwards through it. The stopper body 31 has a first port for inserting a drainage tube in its center, and the protrusion 32 has a second port for inserting a drainage tube in its center. The inner diameter of the first port is the same as the outer diameter of the drainage tube, while the inner diameter of the second port is slightly smaller than the outer diameter of the drainage tube. This design enhances the fixation of the drainage tube by the stopper body, reducing the likelihood of the drainage tube detaching from the drainage bottle under external pulling force. The stopper may be made of rubber.

[0044] In practical applications, the drainage tube is a disposable item. The protective cover or fixing strap can be a disposable medical item for single use, or it can be reused repeatedly after meeting medical disinfection standards for the same patient. Disinfection to meet medical standards can be performed using conventional medical disinfection methods; this is not an improvement of this utility model and is conventional technology in the field, therefore it will not be described in detail.

[0045] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
