Description

Technical Field

[0001] The invention relates to the field of medical care equipment, and in particular to a leakage-proof urinary catheterization device. Background Art

[0002] At present, there are many elderly patients who need to be hospitalized for a long time in the clinic. Some of these patients have loose urethral sphincters, which creates a gap between the urethra and the urethra, resulting in loose wrapping of the urethra around the outer wall of the urethra, which can cause urine leakage. In order to avoid urine leakage, an inflatable balloon is designed in the urethra. After communicating with clinicians, this device has the risk of damaging the urethra and causing pressure sores if the balloon is inflated for a long time, so clinicians are reluctant to use it. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a leakage-proof urinary catheterization device, aiming to solve the problems existing in the above background technology.

[0004] To achieve the above object, the present invention proposes the following technical solutions: A leakage-proof urinary catheter device comprises a urinary catheter body; one side of the urinary catheter body is provided with a liquid discharge port, and the other side is provided with a urine bag interface; a liquid discharge channel is provided inside the urinary catheter body; one end of the liquid discharge channel is connected to the liquid discharge port, and the other end is connected to the urine bag interface; a fixing component and a leakage-proof component are also provided on the urinary catheter body; the fixing component is used to fix the urinary catheter body in the patient's bladder, and the leakage-proof component is used to prevent liquid leakage from the gap between the urethra and the outer wall of the urinary catheter body.

[0005] Furthermore, the fixed component includes a fixed balloon and a fixed balloon inflation chamber; the fixed balloon is arranged on one side of the drainage port; the fixed balloon inflation chamber is arranged inside the catheter body, one end of which is connected to the fixed balloon and the other end is connected to the fixed balloon inflation valve.

[0007] Furthermore, the fixed balloon inflation chamber, the first leak-proof balloon inflation chamber and the second leak-proof balloon inflation chamber are all arranged outside the drainage channel, and have diameters smaller than the diameter of the drainage channel.

DETAILED DESCRIPTION

[0017] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but is not limited thereto. Any modification or equivalent replacement of the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention should be included in the protection scope of the present invention.

[0018] like Figure 1-3 As shown, the present invention proposes a leakage-proof urinary catheter device, including a urinary catheter body 5, a drainage channel 11 is provided inside the urinary catheter body 5, a drainage port 1 is provided on the left outer surface of the urinary catheter body 5, the left end of the drainage channel 11 is connected to the drainage port 1, and the right end is connected to the urine bag interface 9, which is used to guide the urine in the patient's bladder into the urine bag.

[0019] On the catheter body 5, and on the right side of the drainage port 1, a fixed balloon 2, a first leak-proof balloon 3 and a second leak-proof balloon 4 are sequentially arranged; inside the catheter body 5, a fixed balloon filling chamber 21, a first leak-proof balloon filling chamber 31 and a second leak-proof balloon filling chamber 41 are arranged on the outside of the drainage channel 11; the fixed balloon filling chamber 21, the first leak-proof balloon filling chamber 31, the second leak-proof balloon filling chamber 41 do not interfere with the drainage channel 11, and the diameters of the fixed balloon filling chamber 21, the first leak-proof balloon filling chamber 31 and the second leak-proof balloon filling chamber 41 are significantly smaller than the diameter of the drainage channel 11. Correspondingly, the left end of the fixed balloon inflation chamber 21 is only connected to the fixed balloon 2, and the right end extends outward along the catheter body 5, and a fixed balloon inflation valve 6 is connected at the end. The fixed balloon 2 is inflated or filled with saline through the fixed balloon inflation valve 6 to expand the fixed balloon 2 to fix the catheter body 5. Similarly, the left end of the second leak-proof balloon inflation chamber 41 is only connected to the second leak-proof balloon 4, and the right end extends outward along the catheter body 5, and a second leak-proof balloon inflation valve 8 is connected at the end. The first leak-proof balloon inflation valve 7 and the second leak-proof balloon 4 inflation valve are both connected to an inflation pump 12 with an integrated control function. The inflation pump 12 can control the two leak-proof balloons to circulate and inflate and empty, so that while ensuring leak-proof, the leak-proof ball valve can be prevented from continuously compressing the same position of the urethra, thereby causing damage to the urethra.

[0020] like Figure 4As shown, when in use, first insert one end of the catheter body 5 with the drainage port 1 into the patient's bladder along the patient's urethra, and then fill or inject physiological saline into the fixed balloon 2 through the fixed balloon filling valve 6, so that one end of the catheter body 5 is fixed in the patient's bladder. At this time, the fixed balloon 2 is located in the bladder, and the two leak-proof balloons are located in the urethra; then, the first leak-proof balloon 3 is inflated through the inflation pump 12 to expand the first leak-proof balloon 3, so that the urethra can be compressed, thereby preventing the urethra from leaking. The gap between the outer walls of the catheter body 5 leaks liquid. After a few minutes, the air pump 12 controls the second leak-proof balloon 4 to inflate, and at the same time controls the first leak-proof balloon 3 to exhaust, so that the second leak-proof balloon 4 expands and the first leak-proof balloon 3 deflates, thereby changing the compressed position in the urethra. By cyclically inflating and exhausting the two leak-proof balloons, it is possible to ensure leak-proofness while avoiding the leak-proof balloon from continuously compressing the same part of the urethra for a long time, thereby avoiding damage to the urethra while ensuring leak-proofness.

[0021] Preferably, a plurality of scales 13 are provided on the catheter body 5 for displaying the insertion depth of the catheter. A plug 10 is also provided at the left end of the catheter. The end face of the plug 10 is arc-shaped, which, on the one hand, plays a blocking role so that the liquid flows out from the drainage port 1, and on the other hand, avoids damage to the urethra or bladder during the insertion process.

[0022] It should be noted that the interval time of the anti-leakage balloon can be adjusted in time according to the conditions of different patients, and the number of anti-leakage balloons can also be increased in time according to the specific conditions.

[0023] Importantly, it should be noted that the construction and arrangement of the present application shown in a number of different exemplary embodiments are only exemplary.

Therefore, the invention is not limited to a specific embodiment, but extends to numerous modifications still falling within the scope of the appended claims.

[0024] Furthermore, in order to provide a concise description of exemplary embodiments, all features of an actual embodiment may not be described, i.e., those features that are not relevant to the best mode presently contemplated for carrying out the invention or those features that are not relevant to implementing the invention.
