Description

Technical Field

[0001] This utility model relates to the technical field of urinary catheters, and in particular to a visual large flushing chamber smooth tip vertical balloon urinary catheter. Background Technology

[0002] A urinary catheter is used to assist or control the flow of urine from a patient's bladder. When a patient requires catheterization, there may be lesions inside the bladder. Current technology uses ultrasound for detection, but it cannot guarantee a complete picture. This invention employs visualization technology, combining the catheter with an endoscope, allowing for visualization of internal lesions during catheterization, enabling doctors to provide clearer and more intuitive targeted treatment. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a visual, large-cavity, smooth-tip vertical balloon catheter, which solves the technical problem of not being able to visualize lesions during catheterization and achieves the goal of improving the success rate of treatment for doctors.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a visual large flushing chamber smooth tip vertical balloon catheter, including a tube body as a supporting base, wherein a drainage hole is opened in the middle of the inner side of the tube body, an endoscope is slidably connected to the inner side of the drainage hole, and a positioning frame is fixedly connected to the outer side of the endoscope away from the drainage hole.

[0005] Preferably, the maximum diameter of the endoscope is smaller than the inner diameter of the drainage hole, and the maximum diameter of the positioning frame is larger than the maximum diameter of the tube body.

[0006] Preferably, the inside of the pipe body has a flushing hole and a water injection hole on both sides above the drainage hole, and a connecting pipe is fixedly connected to the outside of the pipe body. The two water outlets of the connecting pipe are connected to the water inlet ends of the flushing hole and the water injection hole, respectively.

[0007] Preferably, a plug is fixedly connected to the end of the tube away from the positioning frame, a balloon is fixedly connected to the outer side of the tube near the plug, and elastic silicone reinforcing ribs are fixedly connected at equal intervals to the inner side of the balloon.

[0008] Preferably, the inner side of the balloon has a cavity, and the water outlet of the water injection hole is connected to the cavity on the balloon.

[0009] Preferably, a developing line is fixedly connected inside the tube below the drainage hole, and the water inlet end of the connecting tube extends to the end of the tube near the positioning frame.

[0010] By employing the above technical solution, this utility model provides a visual, large-flushing-chamber, smooth-tip vertical balloon catheter, which has at least the following beneficial effects:

[0011] 1. This utility model adopts a large drainage hole design, which can insert an endoscope and use a plug to hold the endoscope in place to achieve the visualization function.

[0012] 2. The balloon in this utility model adopts a vertical stripe design to increase the strength of the balloon and prevent it from rupturing. At the same time, the vertical stripes also make the folds produced by the balloon when it contracts vertical, reducing the patient's pain when it is removed.

[0013] 3. This utility model adopts a head-end balloon design, with the balloon close to the top to reduce the drainage position.

[0014] 4. This utility model adopts a smooth balloon design, with the balloon having the same outer diameter as the catheter body, making the catheter insertion and withdrawal smoother and reducing pain for the patient during insertion and withdrawal.

[0015] 5. This utility model adopts a flushing hole design with large and irregular cavities to achieve high-flow flushing of the bladder and improve the flushing effect. Attached Figure Description

[0021] 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.

[0022] Example 1

[0023] Current technologies use ultrasound for detection, but this cannot guarantee a completely clear picture. This invention employs visualization technology, combining a urinary catheter with an endoscope. During catheterization, internal lesions can be visualized, allowing doctors to provide clearer and more direct targeted treatment. Please refer to [link / reference]. Figures 1-2 This embodiment provides a visual, large-cavity, smooth-tipped, vertical balloon catheter, solving the technical problem of not being able to view the lesion during catheterization. With existing catheters, operators cannot constantly observe the situation along the way and around the lesion during insertion, hindering timely responses. To address this issue, a component facilitating operator observation is added to the existing catheter. The device includes a tube body 4 as a supporting base, with a drainage hole 2 in the middle of its inner side. An endoscope 10 is slidably connected to the inner side of the drainage hole 2. The new catheter's drainage hole 2 design increases drainage volume, allowing even the smallest portion to pass through the endoscope 10. A positioning frame 11 is fixedly connected to the outer side of the endoscope 10 away from the drainage hole 2. The positioning frame 11 is fixed to the endoscope 10, and when the tip of the endoscope 10 is flush with the tip of the catheter, the positioning frame 11 is positioned at the tail end of the catheter. To prevent the endoscope 10 from going too deep, the maximum diameter of the endoscope 10 is smaller than the inner diameter of the drainage hole 2, and the maximum diameter of the positioning frame 11 is larger than the maximum diameter of the tube body 4. The tube body 4 has a flushing hole 3 and a water injection hole 6 on both sides above the drainage hole 2. A connecting pipe 8 is fixedly connected to the outside of the tube body 4. The two water outlets of the connecting pipe 8 are connected to the water inlet ends of the flushing hole 3 and the water injection hole 6, respectively. The flushing hole 3 and the water injection hole 6 are connected by the connecting pipe 8 to keep them unobstructed during and after the pasting process.

[0024] Example 2

[0025] Based on Example 1, which solved the technical problem of not being able to visualize the lesion during catheterization, Example 1 still has the problem of damaging the patient's urethral wall when the catheter limiting component is pulled out. Figures 1-2As shown, the specific implementation process is as follows: A balloon component is used for catheter positioning. However, after the balloon component inflates and contracts, wrinkles appear on its surface, causing it to scratch the patient's urethral wall when withdrawn. A plug 1 is fixedly connected to the end of the catheter body 4 away from the positioning frame 11. The plug 1 design reduces the length of the balloon tip 5, bringing the balloon 5 closer to the tip and thus lowering the drainage position. The drainage port of the plug 1 is closed, with an inner diameter slightly smaller than the inner hole of the tube body 4. When the endoscope 10 is inserted, it fits perfectly at the tip of the endoscope 10, ensuring visualization. A balloon 5 is fixedly connected to the outer side of the tube body 4 near the plug 1. The part of the balloon 5 is attached to the top of the catheter, lowering the drainage position and making the drainage of the catheter more thorough. The balloon 5 adopts a vertical rib design to prevent horizontal wrinkles when it is inflated and deflated, reducing the pain of the patient when it is removed. Elastic silicone reinforcing ribs 9 are fixedly connected at equal intervals on the inner side of the balloon 5. A cavity is opened on the inner side of the balloon 5, and the water outlet of the water injection hole 6 is connected to the cavity on the balloon 5. A radiopaque line 7 is fixedly connected inside the tube body 4 below the drainage hole 2. The water inlet of the connecting tube 8 extends to the end of the tube body 4 near the positioning frame 11.
