Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a decompression type double-channel urinary catheter. Background Art

[0002] The drainage holes of existing urinary catheters are positioned high, and can only drain urine above the same level as the drainage holes. Urine below the drainage holes will accumulate, causing urinary tract inflammation. When abdominal pressure increases or the urethra size of the urethra does not match the patient's urethra, urine will leak out of the urethra. Utility model patent publication number CN212547910U discloses a urinary catheter specifically for drainage during radical prostatectomy, comprising a tubular body with a drainage channel and a water inlet channel; a balloon disposed on the body, the balloon being located near the front end of the body; a first drainage hole and a second drainage hole disposed on the body, the first drainage hole and the second drainage hole being located on either side of the balloon; a urinary inlet and a water inlet disposed at the rear end of the body; the first drainage hole, the second drainage hole, and the urinary inlet being connected through the drainage channel; and the balloon and the water inlet being connected through the water inlet channel. A second drainage hole is provided to direct urine, blood, fluid accumulation, or secretions from the anastomosis between the bladder and urethra into the drainage channel for further drainage through the urethral opening, thereby resolving the problems of urine retention and leakage. However, the balloon in the aforementioned device has a certain weight when inflated with water and is non-retractable. When the bladder shrinks or the patient continuously changes position, the balloon can irritate the patient's bladder and cause discomfort. Addressing these challenges has become a pressing technical issue. Utility Model Content

[0003] The purpose of the utility model is to provide a decompression type double-channel urinary catheter which can reduce the discomfort of patients, improve the urination efficiency and reduce the probability of urine leakage.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] The utility model provides a decompression double-channel urinary catheter, comprising a tube body; a fixing device capable of adjusting the size is provided at the front end of the tube body and a urine bag is connected to the rear end of the tube body; the fixing device is in the shape of a bowl with the opening upward when expanded to the maximum extent; two excretion channels are provided in the tube body, and the two excretion channels are not connected to each other at one end close to the fixing device; at least one excretion hole is provided on the upper and lower ends of the tube body respectively, and the two excretion holes are respectively connected to different excretion channels.

[0006] Furthermore, the fixing device includes a water bag and a water injection pipe, which are respectively installed at the front end and the rear end of the tube body. The inner wall of the tube body is provided with a water injection channel, and the water injection channel and the excretion channel are not connected to each other. The water injection pipe is connected to the water bag through the water injection channel. After the water bag is filled with water, it is in the shape of a bowl with the opening facing upward.

[0007] Furthermore, after being filled with water, the water bag takes on a hollow hemispherical shape with an opening facing upward.

[0008] Furthermore, the front end of the tube does not pass through the water bag.

[0009] Furthermore, the width of the drainage channel is 2.5-3.5 mm, and the width of the water injection channel is 0.5-1.5 mm.

[0010] Furthermore, the width of the drainage channel is 2.5 mm, and the width of the water injection channel is 1 mm.

[0011] Furthermore, the height of the drainage hole is 4-6 mm, and the width is 1.5-2.5 mm.

[0012] Furthermore, the height of the drainage hole is 5 mm and the width is 2 mm.

[0013] Due to the adoption of the above structure, the utility model has the following beneficial effects:

[0014] When the fixing device of the present invention is expanded to the maximum extent, it is in the shape of a bowl with the opening facing upward. Compared with the traditional balloon, the fixing device of the present invention is not only lighter after being filled with water, but also has a certain deformation ability while ensuring that the tube body does not fall out of the urethra. Therefore, when the bladder is compressed or shrinks, the pressure on the bladder is reduced, thereby reducing the patient's discomfort. By providing two excretion channels and providing at least one excretion hole at the upper and lower ends of the fixing device, the urination efficiency can be improved and the probability of urine leaking from the gap between the urethra and the urethra can be reduced.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please refer to Figure 1 、 Figure 2 The utility model provides a decompression double-channel urinary catheter, comprising a tube body 1; a fixing device 2 capable of adjusting the size is provided at the front end of the tube body 1 and a urine bag 6 is connected to the rear end of the tube body 1; the fixing device 2 is in the shape of a bowl with the opening facing upward when the fixing device 2 is expanded to the maximum extent; two excretion channels 4 are provided in the tube body 1, and the two excretion channels 4 are not connected to each other at one end close to the fixing device 2; at least one excretion hole 3 is provided on the upper and lower ends of the tube body 1, respectively, and the two excretion holes 3 are respectively connected to different excretion channels 4. When the fixing device 2 of the present invention is expanded to the maximum extent, it is in the shape of a bowl with the opening facing upward. Compared with the traditional balloon, the fixing device 2 of the present invention is not only lighter after being filled with water, but also has a certain deformation ability while ensuring that the tube body 1 does not fall out of the urethra, thereby reducing the pressure on the bladder when the bladder is compressed or shrinks, reducing the patient's discomfort; the excretion holes 3 of the present invention can be provided in multiple ways and are respectively opened at the upper and lower ends of the fixing device 2, thereby ensuring that the present invention can perform normal catheterization even when some of the excretion holes 3 are blocked, reducing the probability of urine retention, urinary tract infection and the probability of urine leakage from the gap between the urethra and the tube body 1, and improving the urination efficiency; the two excretion channels 4 are not connected to each other near the end of the fixing device 2 to avoid urine backflow.

[0021] In the present invention, the fixing device 2 includes a water bag 201 and a water injection pipe 202, which are respectively installed at the front end and the rear end of the tube body 1. The inner wall of the tube body 1 is provided with a water injection channel 5, and the water injection channel 5 is not connected with the excretion channel 4. The water injection pipe 202 is connected with the water bag 201 through the water injection channel 5. After the water bag 201 is filled with water, it is in the shape of a bowl with the opening upward. The bowl-shaped water bag 201 can have a certain deformation ability while ensuring that the tube body 1 does not fall out of the urethra, thereby reducing the pressure on the bladder when the bladder is compressed or shrinks, reducing the patient's discomfort.

[0022] In the present invention, the water bag 201 is filled with water and takes on a hollow hemispherical shape with an opening facing upward, thereby having a certain deformation ability while ensuring that the tube body 1 does not fall out of the urethra. When the bladder is compressed or shrinks, the pressure on the bladder is reduced, thereby reducing the patient's discomfort.

[0023] In the present invention, the front end of the tube body 1 does not pass through the water bag 201, thereby preventing the patient's bladder from being compressed or the front end of the tube body 1 from stimulating the patient's bladder when the tube body 1 shrinks, causing discomfort to the patient.

[0024] In the present invention, the width of the drainage channel 4 is 2.5-3.5 mm, and the width of the water injection channel 5 is 0.5-1.5 mm.

[0025] In the present invention, the width of the drainage channel 4 is 2.5 mm, and the width of the water injection channel 5 is 1 mm.

[0026] In the present invention, the height of the drainage hole 3 is 4-6 mm, and the width is 1.5-2.5 mm.

[0027] In the present invention, the height of the drain hole 3 is 5 mm and the width is 2 mm.

[0028] When using the present invention, the tube body 1 is first placed in the patient's urethra. After the front end of the tube body 1 extends into the patient's bladder, water is injected into the water bag 201 through the water injection pipe 202. After the water bag 201 is filled with water, it takes on a bowl-like shape with the opening facing upward. This ensures that the tube body 1 has a certain degree of deformation ability without falling out of the urethra, reducing the pressure of the water bag 201 on the patient's bladder. Urine will enter the two excretion channels 4 inside the tube body 1 through the multiple excretion holes 3 on the tube body 1, and finally flow into the urine bag 6. To remove the tube body 1, first drain all the water inside the water bag 201 through the water injection pipe 202, and then remove the tube body 1.

[0029] The above describes the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the above-mentioned specific embodiments, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can use the above-mentioned disclosed methods and technical contents to make many possible changes and modifications to the technical solutions of the present invention without departing from the scope of the technical solution of the present invention, or modify them into equivalent embodiments with equivalent changes, which does not affect the essential content of the present invention.
