Description

Technical Field

[0001] The utility model relates to the technical field of balloon urinary catheters, in particular to a guiding bougie for placing balloon urinary catheters in patients with benign prostatic hyperplasia. Background Art

[0002] Prostatic hyperplasia (BPH) is a common disease in middle-aged and elderly men. It is related to factors such as aging, environment, and smoking. The main symptoms include frequent urination, urgency, urinary incontinence, nocturia, and dysuria. Treatment of BPH requires the insertion of a balloon catheter. Conventional balloon catheters are mostly made of silicone, so the softer balloon catheters are very difficult to insert into the urethra and require the use of a guide bougie. The existing technology has the following problems:

[0003] In the current guide bougie used in balloon catheters for patients with benign prostatic hyperplasia, the guide bougie needs to be inserted into the balloon catheter to facilitate guiding the patient's urethra into the bladder, which results in a certain friction when the guide bougie is inserted into the balloon catheter, resulting in inflexibility and labor during the insertion process; at the same time, since the current guide bougie is not provided with a positioning structure after the balloon catheter is inserted, the guide bougie and the balloon catheter may be separated. Utility Model Content

[0026] By inserting the bougie tube 2 into the balloon urinary catheter 1, it is convenient to guide the insertion into the patient's urethra. At the same time, the setting of the positioning component 4 facilitates the positioning of the bougie tube 2 and the balloon urinary catheter 1. The setting of the annular groove, the fixing ring and the handle 3 facilitates better use by medical staff and can be adjusted to different angles.

[0027] like Figure 2 - Figure 4 As shown, an arc-shaped bougie 21 is provided on the right side of the bougie tube 2, and the opposite surfaces of the bougie tube 2 and the arc-shaped bougie 21 are provided with positive and negative magnetic attraction areas, and the material of the bougie tube 2 and the arc-shaped bougie 21 is metal. An oil storage pipe 22 is fixedly connected to the left side of the arc-shaped bougie 21, and an anti-slip ring 23 is fixedly connected to the left side of the outer surface of the oil storage pipe 22. The outer surface of the oil storage pipe 22 is provided with strip grooves 24 communicating with the inside and outside on both the front and rear sides. A rubber ring 25 is threadedly connected to the side of the outer surface of the oil storage pipe 22 close to the oil storage pipe 22. A through port 202 communicating with the inside and outside is provided on the right side of the bougie tube 2, and a placement port 201 is provided on the right side of the through port 202. The outer surface of the rubber ring 25 is fixedly connected to the inner wall of the placement port 201, and the interior of the placement port 201 is slidably connected to the outer surface of the anti-slip ring 23. The outer surface of the oil storage pipe 22 is plugged into the interior of the placement port 201, and a flow port is formed between the inner wall of the through port 202 and the outer surface of the oil storage pipe 22.

[0028] The cam 25 is then pulled back to allow the oil to flow out of the cam 22 and into the cam 23. The cam 25 is then pulled back to allow the oil to flow out of the cam 23 and into the cam 23. The cam 25 is then pulled back to allow the oil to flow out of the cam 23 and into the cam 23. The cam 25 is then pulled back to allow the oil to flow out of the cam 23 and into the cam 23.

[0029] like Figure 5As shown, the positioning assembly 4 includes a metal block 45 and two arc-shaped clamping rings 41. The rear sides of the opposite surfaces of the upper and lower arc-shaped clamping rings 41 are movably connected, and the inner walls of the upper and lower arc-shaped clamping rings 41 are fixedly connected to the arc-shaped sponge 42. The inner sides of the arc-shaped sponge 42 overlap the outer surface of the airbag urinary catheter 1. The opposite front sides of the upper and lower arc-shaped clamping rings 41 are overlapped with mounting plates 43. The upper surface of the mounting plate 43 is provided with a slide groove 44. The inner wall of the slide groove 44 on the left side is connected to the inside and outside. The slide groove 44 in the upper and lower mounting plates 43 is mirrored. The upper and lower arc-shaped clamping rings 41 are mirrored. A T-shaped groove communicating left and right is provided on the left side of the metal block 45. The rear sides of the inner walls in the front and rear horizontal directions of the T-shaped groove are connected to the inside and outside. The interior of the T-shaped groove is slidably connected to the interior of the upper and lower slide grooves 44. A socket communicating up and down is provided on the right side of the upper surface of the metal block 45. The interior of the socket is fixedly connected to a magnetic block 46 by magnetic attraction. The surface of the magnetic block 46 is fixedly connected to the surface of the mounting plate 43.

[0030] The bougie tube 2 and the balloon urinary catheter 1 are clamped by the upper and lower arc-shaped clamping rings 41, and the T-slot is made to slide inside the slide groove 44 by pushing the metal block 45. When it slides to the appropriate position, the socket contacts the magnetic block 46, which facilitates the magnetic fixation operation of the metal block 45 made of metal material, prevents the metal block 45 from moving and detaching, and achieves a protective effect during clamping through the setting of the arc-shaped sponge 42.

[0031] The working principle of the guide bougie used for placing an indwelling balloon catheter in patients with benign prostatic hyperplasia will be described in detail below.

[0032] The arc-shaped bougie 21 and the bougie tube 2 are inserted into the interior of the balloon urinary catheter 1. When they are inserted into the appropriate position, the operator holds the arc-shaped bougie 21 and rotates the bougie tube 2 one circle, so that the inner thread of the rubber ring 25 is separated from the outer thread of the oil storage tube 22, and the bougie tube 2 is pulled to move, driving the rubber ring 25 to slide on the outer surface of the oil storage tube 22, and at the same time separating the arc-shaped bougie 21 and the bougie tube 2, so that the lubricating oil flows out from the inside of the strip groove 24 and enters the inner side of the balloon urinary catheter 1 for lubrication, thereby achieving the effect of the arc-shaped bougie 21 and the bougie tube 2 being inserted into the balloon urinary catheter 1. The bougie tube 2 and the balloon urinary catheter 1 are clamped by the upper and lower arc-shaped clamping rings 41, and the T-shaped slot is made to slide inside the slide groove 44 by pushing the metal block 45, and the position is limited by the magnetic block 46.

[0033] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
