Description

Technical Field

[0001] This utility model relates to the field of medical technology, specifically to a detachable urinary leakage prevention catheter. Background Technology

[0002] Urinary catheters are widely used in clinical practice. Patients after urinary system surgery, those with urinary retention, and those with neurogenic bladder require long-term indwelling catheters. In some patients, prolonged catheterization can cause urethral distension, bladder neck balloon malformation, or insufficient inflation of the bladder neck balloon, all of which can lead to poor adhesion between the bladder neck balloon and the bladder neck, resulting in urine leakage. This causes some urine to leak out from the edge of the urethral opening, preventing all urine from leaking out of the catheter, which is inconvenient for the patient. Furthermore, some patients may develop blood clots, which can block the catheter and affect its use. Therefore, we have proposed a detachable urinary leakage prevention catheter. Utility Model Content

[0003] This invention provides a detachable urinary catheter for preventing urinary leakage, which solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a detachable urinary leakage prevention catheter, comprising a main catheter tube, a main channel in the middle of the main catheter tube, and an outlet at one end of the main catheter tube communicating with the main channel. A bladder neck balloon is fixedly installed on the outer side of one end of the main catheter tube, and a bladder neck balloon tube communicating with the bladder neck balloon is fixedly installed inside the main catheter tube. A urethral balloon is fixedly installed on the outer side of one end of the main catheter tube. The urethral balloon has bends on its upper and lower sides that are concave into the urethral balloon, and an external flushing port is provided on the inner side of the bends. A main channel balloon is fixedly installed on the inner side of the main channel at one end of the main catheter tube, and an internal flushing port is provided on the main channel balloon.

[0005] Optionally, the cross-section of the main tubing balloon is gradually inclined downward from the outside to the inside, the internal flushing port is located at the bottom of the main tubing balloon, and the internal flushing port is sealed by the main catheter.

[0006] Optionally, the main catheter tube is internally fixedly equipped with a urethral balloon tube and a main catheter balloon tube, one end of which is fixed to the inside of the urethral balloon and communicates with the inside of the urethral balloon.

[0007] Optionally, one end of the main tubing balloon is fixed to the outside of the main tubing balloon, and the main tubing balloon is connected to the inside of the main tubing balloon. Meanwhile, the other ends of the bladder neck balloon, urethral balloon, and main tubing balloon extend out from the outside of the other end of the main catheter.

[0008] Optionally, an annular support plate is provided on the outer side of one end of the main tube of the urinary catheter, and an annular injection cavity is fixedly connected to the inner wall of the support plate at a position flush with the outer side of the main tube of the urinary catheter, and the injection cavity is provided with multiple through holes.

[0009] Optionally, the bladder neck balloon is fixedly installed on the outside of the main catheter tube, and the bladder neck balloon wraps around the support plate, while the inside of the bladder neck balloon is fixed to the outside of the support plate.

[0010] Optionally, the distance between the bladder neck balloon and the end of the main catheter near the urinary outlet is less than the distance between the urethral balloon and the end of the main catheter near the urinary outlet.

[0011] This utility model has the following beneficial effects:

[0012] 1. This detachable urinary leakage prevention catheter, through the action of the urethral balloon structure, allows some water to enter the outer part of the urethral balloon bend. Then, under the action of gravity, the outer side of the urethral balloon deforms and comes into contact with the urethra, locking it in place and preventing urine leakage. The other part of the injected water flows out from the external flushing port, flushing the urine inside the urethra and cleaning the urine on the outside, preventing infection caused by urine retention, thus making it more convenient to use.

[0013] 2. This detachable urinary leakage prevention catheter expands significantly by injecting water into the urethral balloon. The rebound of the urethral balloon continuously squeezes the water inside, creating flushing water pressure and achieving a thorough urethral flushing effect.

[0014] 3. This detachable urinary leakage prevention catheter works by injecting water into the main tubing balloon, which then inflates, allowing the internal flushing port to extend into the main tubing. The balloon's rebound action continuously squeezes out the water inside, creating flushing pressure and ensuring the main tubing remains clear. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1 to 5 A detachable urinary leakage prevention catheter includes a main catheter 1 with a central access channel inside the main catheter 1 through which urine can be drained from the bladder. An outlet 2, connected to the access channel, is located at one end of the main catheter 1, allowing urine from the bladder to flow smoothly into the access channel. A bladder neck balloon 3 is fixedly installed on the outer side of one end of the main catheter 1. A bladder neck balloon tube 5, connected to the bladder neck balloon 3, is fixedly installed inside the main catheter 1. Water is injected into the bladder neck balloon tube 5, and then delivered into an injection chamber 9 through the bladder neck balloon tube 5, filling the injection chamber 9 with water. As water is injected, the bladder neck balloon 3 inflates and is positioned within the bladder, achieving the effect of catheter fixation. A urethral balloon 4 is fixedly installed on the outer side of one end of the catheter 1. The urethral balloon 4 has indented angles on both the upper and lower sides, and an external flushing port 11 is provided on the inner side of the angles. The angles formed on the urethral balloon 4 can divide the urethral balloon 4 into two parts. By injecting water into the urethral balloon tube 6, the urethral balloon 4 can be greatly expanded. Under the rebound of the urethral balloon 4, the water inside the urethral balloon 4 can be continuously squeezed to form a flushing water pressure, thereby achieving the effect of urethral flushing and ensuring more thorough urethral flushing. A main tube balloon 10 is fixedly installed on the inner side of the main tube at one end of the catheter main tube 1. An internal flushing port 12 is provided on the main tube balloon 10. Water is injected into the main tube balloon 10 and then flushed into the main tube through the internal flushing port 12.

[0024] Please see Figures 1 to 6 The cross-section of the main tube balloon 10 is gradually inclined downward from the outside to the inside. The internal flushing port 12 is located at the bottom of the main tube balloon 10 and is sealed by the main tube of the catheter 1, which can effectively prevent urine from entering the internal flushing port 12 and prevent urine retention from causing bacterial growth.

[0025] Please see Figures 1 to 4 The main catheter 1 has a urethral balloon tube 6 and a main catheter balloon tube 7 fixedly installed inside. One end of the urethral balloon tube 6 is fixed to the inside of the urethral balloon 4 and is connected to the inside of the urethral balloon 4. Water can be injected into the urethral balloon 4 through the urethral balloon tube 6.

[0026] Please see Figures 1 to 4 One end of the main tube balloon 7 is fixed to the outside of the main tube balloon 10, and the main tube balloon 7 is connected to the inside of the main tube balloon 10. Water can be injected into the urethral balloon 4 through the urethral balloon 6. At the same time, the other ends of the bladder neck balloon 5, the urethral balloon 6, and the main tube balloon 7 extend from the outside of the other end of the catheter main tube 1, so that water can be injected smoothly.

[0027] Please see Figures 1 to 4 An annular support plate 8 is provided on the outer side of one end of the main catheter 1. An annular injection chamber 9 is fixedly connected to the inner wall of the support plate 8 at a position flush with the outer side of the main catheter 1. Multiple through holes are provided on the injection chamber 9. Through the support plate 8, the bladder neck balloon 3 can be relatively flush when inserted, reducing the discomfort of insertion.

[0028] Please see Figures 1 to 4 The bladder neck balloon 3 is fixedly installed on the outside of the main catheter 1, and the bladder neck balloon 3 wraps around the support plate 8. At the same time, the inside of the bladder neck balloon 3 is fixed to the outside of the support plate 8. With the support of the support plate 8, the bladder neck balloon 3 can be inserted relatively flush.

[0029] Please see Figures 1 to 4 The distance between the bladder neck balloon 3 and the end of the urinary catheter main tube 1 near the urinary outlet 2 is less than the distance between the urethral balloon 4 and the end of the urinary catheter main tube 1 near the urinary outlet 2. This ensures that after the bladder neck balloon 3 is extended into the bladder, the urethral balloon 4 is located in the urethra, so that the inflation of the urethral balloon 4 can achieve the effect of preventing extravasation.

[0030] In summary, this detachable urinary leakage prevention catheter is used by inserting one end of the catheter main tube 1 (outlet 2) into the urethra. After the bladder neck balloon 3 extends into the bladder, the urethral balloon 4 does not extend into the bladder; instead, it remains within the urethra. Water is then injected into the bladder neck balloon tube 5, which delivers water into the injection chamber 9, filling it with water. This water inflates the bladder neck balloon 3, securing it within the bladder and achieving catheter fixation. When urine begins to leak from the urethral opening, water is injected into the urethral balloon tube 6, allowing water to be delivered into the urethral balloon 4. Some water enters the outer part of the urethral balloon 4's bend, where the weight of the water deforms the outer side of the balloon, causing it to contact and hold the urethra in place, preventing leakage. Another portion of the injected water flows out from the external flushing port 11 to flush the urine in the urethra. After the water injection is stopped, some water will still remain on the outer side of the fold of the urethral balloon 4 to prevent urine leakage. When the urethra needs to be flushed, water is injected into the urethral balloon tube 6, which allows the urethral balloon 4 to expand significantly. Under the rebound of the urethral balloon 4, the water inside the urethral balloon 4 can be continuously squeezed to form flushing water pressure and achieve the flushing effect. When there is a blood clot in the main pipeline, water is injected into the main pipeline balloon tube 7, which allows the main pipeline balloon 10 to expand and extend into the main pipeline. Under the rebound of the main pipeline balloon 10, the water inside the main pipeline balloon 10 can be continuously squeezed to form flushing water pressure and achieve the flushing effect of the main pipeline.
