Description

Technical Field

[0001] The utility model relates to the technical field of ureteral stents, in particular to a holding device for a ureteral stent tube. Background Technique

[0002] The ureteral stent, also known as the double-J tube and the ureteral internal stent tube, mainly functions to drain urine, keep the ureter unobstructed, and help urine drain smoothly from the kidney to the bladder. It is commonly used in cases such as ureteral obstruction (such as stones, stenosis, etc.) and after ureteral injury repair, and can also play a role in supporting the ureter to prevent it from being stenosed or collapsed to promote recovery.

[0003] The existing ureteral stent is similar in shape to the English letter "J", with both ends located in the renal pelvis and the bladder respectively, and the middle section located in the ureter. The J-shaped ends are used to limit its position between the renal pelvis and the bladder. However, since the ureteral stent is soft, during large-amplitude movements such as squatting and jumping by the patient, the J-shaped ends will be straightened due to the movement, causing one end to fall off the organ and lose its limiting property.

[0004] In view of this, we propose a holding device for a ureteral stent tube to facilitate solving the above problems Content of the Utility Model

[0005] The main purpose of the utility model is to provide a holding device for a ureteral stent tube, which can effectively solve the problems mentioned above.

[0027] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] As Figure 1 - Figure 5 As shown in the figure, a holding device for a ureteral stent tube includes a ureter body 1 and a filter ball assembly 2. A balloon two 14 is installed at the top end of the ureter body 1, a balloon one 13 is installed at the bottom end of the ureter body 1, an inner cavity 12 is provided in the ureter body 1, and the balloon two 14 is communicated with the balloon one 13 through the inner cavity 12. A valve assembly 3 is arranged on the balloon one 13;

[0029] By providing the ureter body 1, with a balloon one 13 and a balloon two 14 respectively installed at both ends of the ureter body 1, the ureter body 1 is inserted into the ureter, and the end with the balloon two 14 is inserted into the renal pelvis. The end of the ureter body 1 with the balloon one 13 is inserted into the bladder. The balloon one 13 and the balloon two 14 are inflated through the valve assembly 3 on the balloon one 13, so that the balloon one 13 and the balloon two 14 at both ends expand and are clamped on the renal pelvis and the bladder, avoiding the ureter body 1 detaching from the organ due to stretching during the movement of the patient.

[0030] Further, one end of the ureter body 1 near the balloon one 13 extends into the filter ball assembly 2. The filter ball assembly 2 includes a hemispherical shell one 21 and a hemispherical shell two 22. On the opposite surfaces of the hemispherical shell one 21 and the hemispherical shell two 22, connecting rings 25 that are adapted to each other are respectively installed. On both connecting rings 25, matching connecting threads 251 are provided. Through holes 23 that penetrate are equidistantly arranged on the outer surfaces of the hemispherical shell one 21 and the hemispherical shell two 22.

[0031] By providing the filter ball assembly 2, which is composed of the hemispherical shell one 21 and the hemispherical shell two 22, placing the end of the ureter body 1 with the balloon one 13 in the hemispherical shell one 21 and the hemispherical shell two 22, in this way, the ureter body 1 introduces urine into the filter ball assembly 2 through the urine guiding groove 11. The through holes 23 on the filter ball assembly 2 can filter out sundries such as stones in the urine, avoiding the situation that stones get stuck in the urethra when the patient urinates, or the discomfort caused by the collision between the stones and the urethra when the patient urinates.

[0032] Further, symmetrically arranged limiting holes 24 are respectively opened on the outer surfaces of the tops of the hemispherical shell one 21 and the hemispherical shell two 22. The inner wall diameter between the two limiting holes 24 is larger than the outer wall diameter of the ureter body 1.

[0033] By providing the through limiting holes 24 opened on the outer surfaces of the tops of the hemispherical shell one 21 and the hemispherical shell two 22, and the inner wall diameter between the two limiting holes 24 is larger than the outer wall diameter of the ureter body 1, in this way, while the ureter body 1 can extend out of the hemispherical shell one 21 and the hemispherical shell two 22, the urine guided to the bladder by the urine guiding groove 11 can enter the filter ball assembly 2 through the limiting holes 24 and be filtered.

[0034] Further, a urine guiding groove 11 is opened on the outer surface of the ureter body 1, and the urine guiding groove 11 is spiral.

[0035] In order to avoid the contact between the ureter body 1 and the urethral polyp resulting in closure, by providing the urine guiding groove 11, urine can be introduced into the bladder in the closed state of the urethral polyp and the ureter body 1.

[0036] Further, the air valve assembly 3 includes a housing 31. The housing 31 is fixedly installed on the balloon one 13. A partition plate 32 is fixedly installed in the housing 31. The partition plate 32 divides the interior of the housing 31 into two parts, a chamber one 33 and a chamber two 34. A through air inlet one 35 is opened on the inner top wall of the chamber one 33. A sealing block 331 is arranged in the chamber one 33. The outer wall diameter of the sealing block 331 is larger than the inner wall diameter of the air inlet one 35. A return spring 333 is arranged in the chamber one 33. The head and tail ends of the return spring 333 respectively abut between the sealing block 331 and the partition plate 32.

[0037] The air inlet 1 35 is provided to inflate the first balloon 13 and the second balloon 14. The head and tail ends of the double spring 333 respectively abut between the sealing block 331 and the partition plate 32. In this way, the sealing block 331 is always pushed by the elastic force of the double spring 333, so as to seal the air inlet 1 35 and prevent foreign objects from entering the first chamber 33.

[0038] Furthermore, a through air inlet 2 36 is provided at one end of the housing 31 extending into the first balloon 13. A magnet 341 is fixedly installed on the inner bottom wall of the second chamber 34. A sphere 342 is slidably installed in the second chamber 34. A through hole 321 is provided at the top of the partition plate 32. A push rod 332 is fixedly installed at the bottom of the sealing block 331. The end of the push rod 332 away from the sealing block 331 passes through the hole 321 and contacts the sphere 342.

[0039] By providing the air inlet 2 36, the air inlet 2 36 is communicated with the inside of the first balloon 13. In this way, during the gas filling process, when the air inlet 2 36 is provided, gas enters. During the gas filling process, the sealing block 331 is first pushed downward, thereby driving the push rod 332 to push the sphere 342. In this way, the gas can smoothly enter the first balloon 13 through the air inlet 2 36. When the inflation is completed, due to magnetic repulsion, the magnet 341 pushes the sphere 342 to block the hole 321.

[0040] The working principle of the present utility model is as follows: The first balloon 13 and the second balloon 14 are respectively installed at both ends of the ureter body 1. The ureter body 1 is inserted into the ureter, and the end with the second balloon 14 is inserted into the renal pelvis. The end of the ureter body 1 with the first balloon 13 is inserted into the bladder. The first balloon 13 and the second balloon 14 are inflated through the valve assembly 3 on the first balloon 13, so that the first balloon 13 and the second balloon 14 at both ends expand and are clamped on the renal pelvis and the bladder, avoiding the ureter body 1 from detaching from the organ due to stretching during the patient's movement. By providing the filter ball assembly 2, the filter ball assembly 2 is composed of the first hemispherical shell 21 and the second hemispherical shell 22. The end of the ureter body 1 with the first balloon 13 is placed in the first hemispherical shell 21 and the second hemispherical shell 22. In this way, the ureter body 1 introduces urine into the filter ball assembly 2 through the urine drainage groove 11. The filter holes 23 on the filter ball assembly 2 can filter out impurities such as stones in the urine, avoiding the stones from getting stuck in the urethra when the patient urinates, or causing discomfort to the patient due to the collision between the stones and the urethra during urination.
