[0002] Drainage tubes are medical devices used for clinical surgical drainage, which guide pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage tubes used clinically, some are used for urinary catheterization, some are used for wounds, and they are used in the chest cavity, brain cavity, gastrointestinal tract, bile duct, etc. The purpose of surgical drainage is to guide pus, blood, and fluid accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and affect wound healing. After surgery, many patients may experience a large amount of fluid exudation due to factors such as large surgical scope, severe inflammation, poor nutritional status, and formation of sinus tracts in tissues or organs. In order to avoid fluid accumulation in the body, a drainage device is needed to drain the fluid out of the body.

[0004] However, this utility model still has some shortcomings. For example, when using a drainage tube, the tube near the joint is directly fixed to the patient's skin with tape, which causes the joint to loosen or the tube to shift when the patient turns over, increasing the risk of device-related pressure injury. At the same time, the reserved exposed length of the tube is insufficient, which limits the implementation of the secondary fixation method. Therefore, a solution that can alleviate the above problems is urgently needed. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the anti-slip drainage tube device includes a sterile catheter 1, and a drainage auxiliary mechanism 5 is provided at the upper end of the sterile catheter 1. The drainage auxiliary mechanism 5 includes a connecting tube 51 fixedly connected to the upper end of the sterile catheter 1, and the upper end of the connecting tube 51 is fixedly connected to a guide tube 52, and the upper end of the guide tube 52 is installed with a backflow valve 53, and the upper end of the backflow valve 53 is installed with a drainage tube body 54. The outer side of the drainage tube body 54 is fixedly connected with a connecting strip 55, and the lower end of the connecting strip 55 is provided with an oblique port 56, and one end of the oblique port 56 is fixedly connected to a limiting strip 57, and the upper end of the limiting strip 57 is provided with an inner groove 58, and the outer side of the drainage tube body 54 is fixedly connected with an adsorption ring 59 near the lower side of the connecting strip 55.

[0022] In this embodiment, a medical tape 510 is placed on the inner side of the inner groove 58, the connecting tube 51 and the guide tube 52 are connected, and the connecting tube 51 and the sterile catheter 1 are connected. The main materials of the connecting tube 51 and the drainage tube body 54 are medical silicone or polyvinyl chloride. The upper end of the adsorption ring 59 is fixedly connected to the lower end of the connecting strip 55, and the oblique port 56 is located below the limit strip 57. The shape of the inner groove 58 is trapezoidal, and the shape of the adsorption ring 59 is truncated cone. The main material of the adsorption ring 59 is rubber.

[0023] Specifically, the drainage tube body 54 is inserted into the patient's body, and the adsorption ring 59 is located on the patient's external skin. Then, the medical tape 510 is placed in the inner groove 58, and the medical tape 510 is pulled to stick the medical tape 510 on the patient's skin. The medical tape 510 exerts pressure on the limiting strip 57, and the medical tape 510 is located in the inner groove 58, so that it is closer to the patient's skin, so that the limiting strip 57 presses the connecting strip 55 on the patient's skin, and the oblique port 56 is attached to the patient's skin, so that the connecting strip 55 can better bring the adsorption ring 59 closer to the patient. And the adsorption ring 59 is deformed, so that the adsorption ring 59 becomes flat and thin, and then the adsorption ring 59 is tightly adsorbed on the patient's body, thereby preventing the drainage tube main body 54 from falling off. After the limiting strip 57 is fixed to the patient's skin by the medical tape 510, the connecting strip 55 will simultaneously complete two key actions under the action of pressure: one is to push the oblique port 56 to fit completely with the skin, and the other is to flatten the adsorption ring 59 to form negative pressure adsorption. This double fixing mechanism can effectively prevent the drainage tube main body 54 from falling off, which not only ensures the stability of the drainage tube main body 54 when the patient turns over, but also provides a convenient basis for secondary fixation.

[0024] In this embodiment, the lower end of the sterile catheter 1 is fixedly connected to a water seal bag 2, and an exhaust port 3 is installed on the upper end of the water seal bag 2 close to the side of the sterile catheter 1. The lower end of the water seal bag 2 is fixedly connected to a pull strip 4, and the sterile catheter 1 and the water seal bag 2 are connected. The main materials of the sterile catheter 1 and the water seal bag 2 are both medical silicone or polyvinyl chloride.

[0025] Specifically, the medical staff first lifts the pull strip 4, places the water seal bag 2 under the patient's body, and limits the water seal bag 2 to the patient's bedside, and then inserts the drainage tube body 54 into the patient's body, and then the liquid in the patient's body can be drained.

[0026] Working principle:

[0027] During use, the medical staff first lifts the pull strip 4, places the water seal bag 2 under the patient's body, and limits the water seal bag 2 to the patient's bedside, then inserts the drainage tube body 54 into the patient's body, and makes the adsorption ring 59 be located on the patient's external skin, then places the medical tape 510 into the inner groove 58, and pulls the medical tape 510, and sticks the medical tape 510 on the patient's skin, so that the medical tape 510 exerts pressure on the limiting strip 57, and makes the medical tape 510 located in the inner groove 58, so that it is closer to the patient's skin, so that the limiting strip 57 presses the connecting strip 55 on the patient's skin, and makes the oblique port 56 fit on the patient's skin. , so that the connecting strip 55 can better bring the adsorption ring 59 closer to the patient, and the adsorption ring 59 can be deformed, so that the adsorption ring 59 becomes flat and thin, and then the adsorption ring 59 is tightly adsorbed on the patient's body, thereby preventing the drainage tube main body 54 from falling off. After fixing the limiting strip 57 to the patient's skin with the medical tape 510, the connecting strip 55 will simultaneously complete two key actions under the action of pressure: one is to push the oblique port 56 to fit completely with the skin, and the other is to flatten the adsorption ring 59 to form negative pressure adsorption. This dual fixing mechanism can effectively prevent the drainage tube main body 54 from falling off, which not only ensures the stability of the drainage tube main body 54 when the patient turns over, but also provides a convenient basis for secondary fixation.
