Detailed implementation manner

[0036] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] The present invention provides a Figure 1 and Figure 10 shown medical urological expansion and drainage device, including:

[0038] The first drainage tube 1, one end of the first drainage tube 1 is fixedly connected to the first connecting tube 2, one end of the first connecting tube 2 is provided with a second connecting tube 3, and one end of the second connecting tube 3 is hemispherical;

[0039] The expansion balloon 4, the expansion balloon 4 is fixedly arranged at the outer end of the second connecting tube 3, the cross-section of the expansion balloon 4 is L-shaped, and a plurality of silicone blocks 5 are fixedly arranged between the inner wall of one end of the expansion balloon 4 close to the hemispherical end of the second connecting tube 3 and the outer end of the hemispherical end of the second connecting tube 3. A plurality of drainage channels 6 are formed between the outer end of the second connecting tube 3, the inside of the expansion balloon 4 and the plurality of silicone blocks 5. A plurality of drainage openings 7 communicating with its inside are opened at the outer end of the second connecting tube 3, and the inside of the second connecting tube 3 and the inside of the drainage channel 6 are communicated through the drainage openings 7;

[0040] The inflation tube 8, one end of the inflation tube 8 is communicated with the inside of the expansion balloon 4, and the other end of the inflation tube 8 is connected to an external inflation and deflation device.

[0041] A collection cylinder 18 is arranged at the bottom of the first drainage tube 1. The collection cylinder 18 is made of a transparent material, and the top of the rear end of the collection cylinder 18 is connected to an external negative pressure pumping device.

[0042] Insert the second connecting tube 3 into the urethral calculus of the patient. The hemispherical end of the second connecting tube 3 will come into contact with the calculus. At this time, an external inflation and deflation device inflates the inside of the dilation balloon 4, and the dilation balloon 4 will dilate the urethra near the calculus. An external negative pressure extraction device evacuates the inside of the collection cylinder 18 to negative pressure. Urine will flow through multiple drainage channels 6 and multiple drainage ports 7 into the second connecting tube 3 and the first drainage tube 1, and then enter the collection cylinder 18. The inflation and deflation device and the negative pressure extraction device are both prior arts and are not shown and described herein.

[0043] The present invention dilates the urethra of the patient through the dilation balloon 4 and multiple silica gel blocks 5, and then drains urine from the patient's urethra through multiple drainage channels 6 and drainage ports 7, which can effectively avoid calculus blockage and ensure the drainage efficiency. This embodiment specifically solves the problem existing in the prior art that in a medical urological dilation and drainage device when dilating and draining urine for a patient with urethral calculus, most of the drainage ports on the drainage tube are at the end. When the calculus blocks in the urethra, the dilation and urination structure needs to be close to the calculus to dilate the urethra at the calculus blockage site so that urine can flow out smoothly. However, at this time, the end of the urine drainage tube is close to the calculus, and the situation of the calculus blocking the drainage port may occur, which will affect the smooth urination of the patient.

[0044] The present invention provides a medical urological dilation and drainage device as Figures 6 to 10 shown. One end of the first connecting tube 2 is integrally connected with a plugging ring 9. A plugging groove 10 is opened on the inner wall of the bottom end of the second connecting tube 3.

A first limiting component is arranged on the plugging ring 9.

[0045] The first limiting component includes multiple cavities 13 opened inside the plugging ring 9. A limiting plate 14 is arranged inside the cavity 13. A first limiting rod 15 is fixedly arranged on the outer side of the limiting plate 14. Multiple silica gel soft sleeves 16 are fixedly arranged at the outer end of the second connecting tube 3. One end of the first limiting rod 15 passes through the outer end of the plugging ring 9 and the second connecting tube 3 and extends into the silica gel soft sleeve 16. The inner side of the limiting plate 14 is fixedly connected with a first spring 17. One end of the first spring 17 is fixedly connected with one end inside the cavity 13.

[0046] By pressing multiple silicone soft sleeves 16, one end of the first limiting rod 15 can be pressed into the interior of the cavity 13. At this time, the first limiting rod 15 drives the limiting plate 14 to compress the first spring 17. At this time, the first connecting pipe 2 and the second connecting pipe 3 can be disassembled, so that the second connecting pipe 3 and the expansion air bag 4 can be cleaned or replaced. The first limiting component is used to limit and fix the insertion ring 9 at the connection between the first connecting pipe 2 and the second connecting pipe 3, enhancing the connection stability of the insertion ring 9, and facilitating the disassembly, replacement and cleaning of the second connecting pipe 3 and the expansion air bag 4.

[0047] The present invention provides a medical urological dilation and drainage device as shown in Figure 1 and Figures 3 to 5 At the top of the collection cylinder 18, two fixed plates 19 are fixedly provided.

An outer end of the rotating square rod 23 is sleeved with a second spring 27. Two ends of the second spring 27 are respectively fixedly connected with the outer side of the rotating disc 24 and the inner side of the connecting plate 26. A second limiting component is arranged inside the rotating disc 24.

[0049] The second limiting component includes a second limiting rod 28 fixedly arranged at the inner edge of the rotating disc 24. A plurality of limiting grooves 29 are formed on the outer side of the fixed plate 19 close to the rotating disc 24. The plurality of limiting grooves 29 are arranged on the outer side of the other end of the hollow winding roller 20. One end of the second limiting rod 28 is inserted into one of the limiting grooves 29.

[0050] Hold the handle 25 with the hand and drive the handle 25 to move outward. The rotating disk 24 drives one end of the second limiting rod 28 to leave the inside of the limiting groove 29 and compresses the second spring 27. At this time, rotate the rotating disk 24. The rotating disk 24 drives the rotating square rod 23 and the hollow winding roller 20 to rotate. In this way, the first drainage tube 1 can be retracted and extended, and the length of the first drainage tube 1 can be adjusted according to actual needs. After the adjustment is completed, release the handle 25. The rotating disk 24 drives one end of the second limiting rod 28 to insert into one of the limiting grooves 29 under the elastic force of the second spring 27. By driving the rotating square rod 23 and the hollow winding roller 20 to rotate through the rotating disk 24, the first drainage tube 1 can be stored, so that it can release an appropriate length according to actual needs, enhancing the applicability of the device. Then, the second limiting component is used to limit and fix the rotating disk 24, the hollow winding roller 20, etc., so that its storage is relatively stable.

[0051] The present invention provides a medical urological dilatation and drainage device as shown in Figure 2 Inside the collection cylinder 18, there is a rotating rod 30.
