[0002] When patients undergo radical cystectomy and ureterocutaneous stoma surgery, ureteral stents are needed for drainage and to promote stoma healing during the perioperative period. Postoperative long-term drainage may lead to urinary tract infection, stoma stenosis, and hydronephrosis. However, existing ureteral stents often have problems such as easy slippage, difficulty in flushing, difficulty in obtaining urine culture after surgery, easy contamination, and inability to monitor hydronephrosis and increased intrarenal pressure in a timely manner. Utility Model Content

[0012] Preferably, the end of the single-J tube side support inside the threaded cap and the inner cap is provided with a limiting ring. The limiting ring is used to prevent the single-J tube side support from falling out of the threaded cap and the inner cap. The inner wall of the inner cap is provided with two protrusions on the upper side. The two protrusions are used to fix the limiting ring.

[0013] Compared with the prior art, this utility model provides a medical anti-slip, easy-to-wash, and pressure-measuring single "J" tube, which has the following beneficial effects:

[0014] For patients with ureterocutaneous stomas, this method provides adequate drainage, facilitates irrigation, and makes pressure measurement easier, reducing the risk of hydronephrosis and urinary extravasation caused by ureteral stent blockage postoperatively. It also facilitates postoperative sampling and timely monitoring of intrarenal pressure, solving problems such as easy slippage of ureteral stents and difficulty in irrigation during the perioperative period. The main body of the single-J stent can be inserted into the ureter or renal pelvis, and the detachable and movable fixation kit can be fixed to the annular protrusion on the J-stent body. The main branch of the single-J stent can be connected to a drainage bag or placed in a stoma bag, while the side branches of the single-J stent can be suspended and fixed externally or fixed in a stoma bag. The end can be connected to various measuring instruments.

[0015] For patients who have undergone radical cystectomy and have ureterocutaneous ureterostomy for pelvic ureteral drainage, it is better to prevent postoperative ureteral stent slippage, facilitate postoperative ureteral stent flushing, and promptly flush out necrotic tissue and foreign bodies, making it easier to resolve ureteral stent blockage. Postoperative care for patients can include routine measurement of intrarenal pressure and timely monitoring of the patient's intrarenal drainage status. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figures 1-3 The medical anti-slip, easy-to-wash, and pressure-measuring single "J" tube shown includes a single J tube annular portion 8 and a single J tube body 7.

[0022] The single-J tube body 7 has a single-J tube annular part 8 at the right end and a single-J tube side branch 5 at the left end. A drainage bag 10 is provided on the lower side of the single-J tube side branch 5. The single-J tube side branch 5 and the drainage bag 10 are connected through the side branch flushing sampling end 3.

[0023] The single-J tube ring 8 at the right end of the single-J tube body 7 is embedded in the patient's renal pelvis. The urine discharged from the kidney is guided outward through the single-J tube body 7 and flows to the drainage bag 10 for collection and storage.

[0024] like Figure 1 As shown, the outer wall of the single-J tube body 7 is provided with a data scale 14, which is used to check the depth of the single-J tube body 7 inserted into the patient's body. The single-J tube body 7 is made of medical non-toxic transparent soft polyvinyl chloride plastic or high-performance polyolefin thermoplastic elastomer TPE material.

[0025] Data scale 14 is used to check the depth of the single-J tube body 7 inserted into the patient's body. By checking the data scale 14 between the patient's skin wound and the outer wall of the single-J tube body 7, it is possible to see if there are any signs of the single-J tube body 7 falling outward.

[0026] like Figure 1 and Figure 3 As shown, a slot 6 is provided on the inner wall of the right end of the single-J tube side branch 5, and a insertion ring 16 is provided on the left end of the single-J tube body 7. The single-J tube body 7 is inserted into the slot 6 through the insertion ring 16 and connected and fixed to the single-J tube side branch 5. The distance between the single-J tube side branch 5 and the end of the single-J tube in the kidney is 20 to 25 cm. The branch is 5 to 10 cm long and the included angle is 10 to 15 degrees. The side branch flushing and sampling end 3 can be connected to various detection devices.

[0027] The main body 7 of the single J tube is inserted into the slot 6 via the insertion ring 16 and is connected and fixed to the side branch 5 of the single J tube. The main body 7 of the single J tube and the side branch 5 of the single J tube connected by insertion can be quickly disassembled, which is more convenient when replacement is needed.

[0028] like Figure 1 and Figure 2 As shown, the drainage bag 10 is provided with a stoma end 1 at the upper end, and the side branch flushing and sampling end 3 is connected to the drainage bag 10 through the stoma end 1. A metal connecting tube 4 is inserted into the left end of the single J tube side branch 5, and a discharge tube 9 is provided at the right end of the drainage bag 10. A plug 15 is sleeved on the right end of the discharge tube 9, and the liquid in the drainage bag 10 can be discharged to the outside through the discharge tube 9.

[0029] The drainage bag 10 is used to collect urine. When the urine in the drainage bag 10 is almost full, the plug 15 at the right end of the discharge tube 9 can be pulled out to pour out the urine in the drainage bag 10, so that the drainage bag 10 can continue to collect urine.

[0030] like Figure 1 and Figure 2 As shown, a threaded cap 2 and an inner cap 13 are provided between the two single J-tube side supports 5. The two single J-tube side supports 5 are respectively inserted into the threaded cap 2 and the inner cap 13 and connected and fixed by screwing. Limiting rings 11 are respectively provided at the ends of the single J-tube side supports 5 in the threaded cap 2 and the inner cap 13. The limiting rings 11 are used to prevent the single J-tube side supports 5 from falling out of the threaded cap 2 and the inner cap 13. The inner wall of the inner cap 13 is provided with two protrusions 12 on the upper side. The two protrusions 12 are used to fix the limiting rings 11.

[0031] The single J-tube side branch 5 is connected and fixed to the outer wall of the inner cap 13 by screwing the threaded cap 2, and the limiting ring 11 inside the threaded cap 2 can be fixed by the squeezing of the inner cap 13, while the limiting ring 11 inside the inner cap 13 is fixed by the snap-fit ​​of the protrusion 12.

[0032] The working principle of this invention is as follows: The annular portion 8 of the single-J stent body 7 at the right end is embedded in the patient's renal pelvis. The single-J stent body 7 guides urine discharged from the kidney outwards, which then flows to the drainage bag 10 for collection and storage. For patients undergoing radical cystectomy with ureterocutaneous ureteropelvic drainage, this invention better prevents postoperative ureteral stent slippage, facilitates postoperative ureteral stent flushing, and allows for timely removal of necrotic tissue and foreign bodies, easily resolving ureteral stent blockage issues. Postoperative care includes routine measurement of intrarenal pressure and timely monitoring of the patient's renal drainage status.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
