DETAILED DESCRIPTION

[0026] 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.

[0027] like Figure 1 and Figure 2 As shown, a pressure-adjustable ureteral drainage tube includes a medical balloon 1 and a drainage tube 2. The upper end of the drainage tube 2 passes through the lower part of the outer surface of the medical balloon 1 and extends to the upper part of the outer surface of the medical balloon 1. The middle part of the outer surface of the drainage tube 2 is slidingly connected to a movable structure 4. The movable structure 4 is rotatably connected to a support structure 3 abutting the inner cavity of the medical balloon 1. The outer surface of the movable structure 4 is provided with traction wires 5 distributed in a ring.

[0028] When the device is used, it is first inserted into the bladder through the urethra. The smooth, oval outer surface of the medical balloon 1 protects the patient's urethra and prevents scratches. The upper end of the movable structure 4 is then moved downward along the outer surface of the drainage tube 2 by pulling the traction wire 5. Simultaneously, the support rods 31 are rotated, bringing the two support rods 31 closer together and pushing the arc-shaped support plate 34 outward, thereby expanding the medical balloon 1 from the inner cavity. The expanded size of the medical balloon 1 is adjusted by adjusting the position of the upper end of the cannula 43, thereby regulating the pressure inside the bladder.

[0029] See Figure 3 and Figure 4 A plurality of circular holes 21 are opened on the upper part of the drainage tube 2, a sealing cover 22 is fixedly connected to the top of the drainage tube 2, and a spring 11 is fixedly connected to the bottom end of the sealing cover 22 and the upper part of the outer surface of the medical balloon 1.

[0030] Before use, spring 11 seals the top of drainage tube 2 with sealing cap 22. Since the lumen of medical balloon 1 is not expanded, circular hole 21 in the upper portion of drainage tube 2 is located within the lumen of medical balloon 1. When the lumen of medical balloon 1 is expanded by arc-shaped support plate 34, the upper end of medical balloon 1 moves downward, exposing circular hole 21. Urine in the bladder can then flow through circular hole 21 into the lumen of drainage tube 2 and be collected.

[0031] See Figure 4 A plurality of chutes 24 are provided in the middle of the outer surface of the drainage tube 2, a plurality of fixed structures 23 adapted to the chutes 24 are fixedly connected to the inner cavity of the drainage tube 2, and a baffle 25 is fixedly connected to the middle and lower part of the outer surface of the drainage tube 2.

[0032] See Figure 4 The fixed structure 23 includes a circular plate 231, one end of the circular plate 231 is fixedly connected to the inner cavity of the drainage tube 2 with a spring 232, one end of the circular plate 231 is fixedly connected to the inner cavity of the spring 232 with a slider 233, and the end of the slider 233 away from the circular plate 231 is slidably connected to the inner cavity of the slide groove 24.

[0033] In this embodiment, the slider 233 is shaped such that the upper portion of one end thereof that is slidably connected to the inner cavity of the slide groove 24 is arc-shaped.

[0034] Specifically, when the entire device is activated, the inner cavity of the sleeve 43 squeezes the top of the slider 233, so that the slider 233 drives the circular plate 231 to move toward the inner cavity of the drainage tube 2, and the second spring 232 is stretched.

[0035] When the upper fixing plate 41 is pulled downward, the upper part of the sleeve 43 slides downward. When the top of the sleeve 43 is lower than the lower end of the inner cavity of the slide groove 24, the slider 233 is no longer squeezed. At this time, the spring 232 returns to its original state, driving the slider 233 to move toward the outer surface of the drainage tube 2. Then the bottom end of the slider 233 contacts the top of the sleeve 43, thereby fixing the position of the upper part of the sleeve 43, thereby fixing the rotation angle of the support rod 31, and expanding the medical balloon 1 from the inner cavity at one time, applying pressure to the bladder and adjusting the pressure appropriately.

[0036] The material of the sleeve 43 in this solution is an existing medical material that has a certain elasticity and can be deformed and then restored to its original shape.

[0037] See Figure 4 and Figure 5 The movable structure 4 includes a sleeve 43, the bottom end of the sleeve 43 is fixedly connected to the upper end of the baffle 25, the inner cavity of the sleeve 43 is slidably connected to the middle part of the outer surface of the drainage tube 2, and the upper and lower parts of the outer surface of the sleeve 43 are annularly distributed and fixedly connected with a plurality of fixed plates 41, and two adjacent fixed plates 41 are connected to a rotating shaft 42 for rotation together, and the bottom ends of the two adjacent fixed plates 41 located on the upper part of the outer surface of the movable structure 4 are fixedly connected to the top of the traction wire 5.

[0038] Specifically, when the traction wire 5 is pulled downward, the lower end of the sleeve 43 is blocked by the upper end of the baffle 25 and does not move. The traction wire 5 drives the fixed plate 41 on the upper outer surface of the sleeve 43 to move downward, thereby causing the upper end of the sleeve 43 to move downward, thereby driving the end of the support rod 31 that is connected to the outer surface of the rotating shaft 42 to move downward. When the traction wire 5 is pulled down to the appropriate position, the upper end of the sleeve 43 contacts the bottom end of the slider 233, and the position of the fixed sleeve 43 does not shift.

[0039] See Figure 3 and Figure 5 The support structure 3 includes two support rods 31 rotatably connected to the middle of the outer surface of the rotating shaft 42. The two support rods 31 are rotatably connected to the rotating rod 32 at one end away from the sleeve 43. The outer surfaces of both ends of the rotating rod 32 are rotatably connected to support plates 33. The two support plates 33 are fixedly connected to an arc support plate 34. The side of the arc support plate 34 away from the support plate 33 abuts against the inner cavity of the medical balloon 1.

[0040] When the support rod 31 rotatably connected to the outer surface of the upper end rotating shaft 42 is driven downward, it rotates around the rotating rod 32 and pushes the rotating rod 32 and the support plate 33 toward the inner cavity of the medical balloon 1, so that the arc support plate 34 supports the inner cavity of the medical balloon 1, so that the medical balloon 1 is expanded from the inside, and at the same time, the upper part of the medical balloon 1 moves downward to expose the circular hole 21, so that the urine in the bladder enters the inner cavity of the drainage tube 2 and flows out.

[0041] See Figure 2The middle of the outer surface of the traction wire 5 is located between two adjacent fixing plates 41 at the lower part of the outer surface of the sleeve 43, and the bottom end of the traction wire 5 passes through the lower part of the inner cavity of the medical balloon 1 and extends to the lower part of the outer surface.

[0042] The working principle of this utility model is:

[0043] First, the user inserts the unactivated device into the bladder through the patient's urethra, and at the same time pulls down the bottom end of the traction wire 5, so that the upper part of the sleeve 43 and the fixed plate 41, the rotating shaft 42 and one end of the support rod 31 are driven downward, and the medical balloon 1 is expanded from the inner cavity by the support rod 31 in cooperation with the rotating rod 32 and the support plate 33 and the arc support plate 34. At the same time, the upper part of the medical balloon 1 moves downward along the upper outer surface of the drainage tube 2, exposing the circular hole 21, so that the urine in the bladder enters the inner cavity of the drainage tube 2. When the medical balloon 1 is expanded to the appropriate position, stop pulling the traction wire 5. At this time, the upper end of the sleeve 43 contacts the bottom end of the slider 233, fixing the position of the sleeve 43 and thus fixing the shape of the medical balloon 1.

[0044] When the patient no longer needs to use the device, the user can push the slider 233 toward the inner cavity of the drainage tube 2, and the upper sleeve 43 drives the rotating shaft 42 and the support rod 31 upward, while no longer squeezing the inner cavity of the medical balloon 1. At the same time, the upper part of the medical balloon 1 moves upward, closing the circular hole 21, and then the device is taken out.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
