Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a kidney puncture drainage fixation device. Background Art

[0002] Clinically, some patients with advanced cancers, especially those who have undergone repeated radiotherapy, are often unable to undergo urinary diversion surgery. To address urinary tract obstruction, a long-term nephrostomy tube is required. Current methods for securing nephrostomy tubes include a balloon (similar to a urinary catheter) and suture fixation. Due to the small space within the renal pelvis, the balloon cannot be injected too large, typically 1-3 ml. During long-term placement, even a slight leak in the balloon can cause the tube to slip. The probability of slippage increases over time, and most patients only become aware of slippage when they discover a lack of urine in the tube or experience back pain. Consequently, many patients require additional surgery to reinsert the nephrostomy tube, significantly increasing their suffering. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0019] In this embodiment, if Figure 1 and Figure 2 As shown, a renal puncture drainage fixation device includes a fixing plate 1. Preferably, the fixing plate 1 is arc-shaped. An adhesive layer 14 is provided on the lower surface of the fixing plate 1. An exhaust pipe 3 is provided on the fixing plate 1. The air inlet of the exhaust pipe 3 is located on the inner side of the adhesive layer 14, and an air plug 15 is provided in the exhaust pipe 3. A through hole is opened in the middle of the fixing plate 1, and the through hole is connected to the fistula opening. A fixing platform 2 is provided on the inner side of the fixing plate 1. A fixing hole 5 and a fixing mechanism 4 are provided on the upper surface of the fixing platform 2. The fixing mechanism 4 is used to fix the fistula tube passing through the fixing hole 5. The end of the fistula tube is connected to the fistula bag, and the fistula bag is connected to an external urine collection bag through a pipeline. The fixing plate 1 is adhered to the skin through the adhesive layer 14, and the air between the fixing plate 1 and the skin is extracted through the exhaust pipe 3, thereby forming a negative pressure to ensure the stability of the adhesion of the fixing plate 1. The fistula tube is then inserted into the fistula opening through the fixing hole 5 and fixed with the fixing mechanism 4 to prevent the fistula tube from falling off.

[0020] Furthermore, the fixing mechanism 4 includes a fixing rod a8 and a fixing rod b9, a rotating rod 13 is provided on the fixing platform 2, and the fixing rod a8 and the fixing rod b9 are cross-arranged on the rotating rod 13, a fixing groove a7 is provided at the end of the fixing rod a8, a fixing groove b6 is provided at the end of the fixing rod b9, a handle 10 is provided at the other end of the fixing rod a8 and the fixing rod b9, and a spring 11 is provided between the fixing rod a8 and the fixing rod b9, and a limit block 12 is provided on the fixing platform 2. Specifically, after the fixing plate 1 is fixed, the fistula tube is inserted into the fistula opening through the fixing hole 5. At this time, the user holds the handle 10 to close the rear ends of the fixing rod a8 and the fixing rod b9, so that the fistula tube is located in the fixing groove a7 and the fixing groove b6, and then the fistula tube is limited and fixed. Finally, the limit block 12 is stuck on the inner side of the handle 10 to prevent the fixing rod a8 and the fixing rod b9 from opening, thereby ensuring the stability of the fixation of the fistula tube. When the fistula tube does not need to be fixed, the handle 10 is held to separate the rear ends of the fixing rod a8 and the fixing rod b9, and the spring 11 can ensure the separation angle of the fixing rod a8 and the fixing rod b9.

[0021] Further, if Figure 3 As shown, the air blocking plug 15 is provided with an opening 16, which includes an opening a and an opening b, which are perpendicular to each other. Specifically, after the fixing plate 1 is adhered to the skin via the adhesive layer 14, the user inserts a needle into the opening 16 to remove the air between the fixing plate 1 and the skin, thereby creating a negative pressure. After the air is removed, the needle is removed. The function of the air blocking plug 15 is to ensure airtightness. In this embodiment, to ensure airtightness, a cap can also be provided at the end of the air extraction tube 3 to prevent external air from entering the area between the fixing plate 1 and the skin through the air extraction tube 3.

[0022] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
