Description

Technical Field

[0001] The utility model relates to the technical field of urinary catheters, in particular to a urinary catheter with an anti-blocking structure. Background Art

[0002] The catheter is a tube made of natural rubber, silicone rubber or polyvinyl chloride. When in use, it is inserted into the bladder through the urethra. After the catheter is inserted into the bladder, there is an air bag near the head of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to the urine bag to collect urine.

[0003] In the existing urinary catheter, since the airbag needs to be inflated or filled with water, the urinary catheter here is easily affected by the air pressure and water pressure, causing the urinary catheter here to deform and narrow, and easily become blocked, causing the patient to urinate poorly;

[0004] The existing patent (publication number: CN218391848U) discloses an anti-blockage catheter. This utility model provides a rigid support tube at the position corresponding to the catheter channel and the air bag, which can effectively reduce the pressure effect of the gas or liquid in the balloon on the catheter channel.

[0005] In view of the above problems, the existing patents provide solutions, but the aperture at the entrance of the existing catheter is small. Therefore, when the patient's urine carries impurities such as blood clots, crystal particles, and stone fragments, the urine is easily blocked when entering the entrance of the catheter, so that the urine cannot be discharged from the body in time, causing the bladder to be overfilled and increasing the risk of bladder rupture. At the same time, urine accumulation may also cause urinary tract infection, seriously affecting the patient's health.

[0006] Therefore, a urinary catheter with an anti-blocking structure is proposed. Utility Model Content

[0007] The utility model aims to provide a urinary catheter with an anti-blocking structure, which can solve the problem that the aperture at the entrance of the existing urinary catheter is small, so that when the patient's urine carries impurities such as blood clots, crystal particles and stone fragments, the urine is easily blocked when entering the entrance of the urinary catheter, so that the urine cannot be discharged from the body in time, causing the bladder to be overfilled, increasing the risk of bladder rupture, and at the same time, urine accumulation may also cause urinary tract infection, seriously affecting the patient's health.

[0008] To achieve the above object, the utility model provides the following technical solutions: a urinary catheter with an anti-blocking structure, comprising a urinary catheter head, the top and bottom of the urinary catheter head are both provided with urinary catheter holes, the inside of the urinary catheter hole is provided with an anti-blocking structure, the rear side of the urinary catheter head is provided with a spiral urinary catheter structure, and the outer side of the spiral urinary catheter structure is provided with an airbag structure;

[0009] The anti-blocking structure comprises a filter frame arranged inside the urinary catheter hole, a primary filter screen is arranged on the top of the filter frame, a fine filter screen is arranged on the bottom of the filter frame, and the fine filter screen is located at the bottom of the primary filter screen.

[0010] Preferably, the spiral catheter structure comprises a catheter tube connected to the rear side of the catheter head, and a connecting groove is provided on the rear side of the interior of the catheter tube.

[0011] Preferably, the interior of the urinary catheter is provided with a self-cleaning coating, and the self-cleaning coating has hydrophilicity and antibacterial properties.

[0012] Preferably, a spiral guide plate is provided inside the urinary catheter, and the spiral guide plate is located on the inner side of the self-cleaning coating.

[0013] Preferably, the airbag structure comprises an air guide tube arranged outside the urinary catheter, the front side of the air guide tube is connected to an airbag, and the airbag is located on the front side of the surface of the urinary catheter.

[0014] Preferably, the rear side of the top of the air guide tube is connected to an air supply pipe, and the rear side of the air supply pipe is connected to an air valve.

[0016] Preferably, a ring band is provided on the outer side of the water valve, a plugging cover is bolted to the rear side of the ring band, and the plugging cover is clamped inside the water valve.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The present application provides an anti-blocking structure, a double-layer design of a primary filter and a fine filter, and can grade and filter impurities such as blood clots, crystal particles, and stone fragments in urine. The primary filter can block larger impurities, such as stone fragments and larger blood clots, to prevent them from entering the spiral catheter structure and causing blockage. The fine filter further filters smaller crystal particles, etc., to ensure that the urine entering the spiral catheter structure is as pure as possible, greatly reducing the risk of blockage. In this way, by effectively filtering impurities, urine can be discharged from the body in time, avoiding overfilling of the bladder caused by urine blockage, reducing the risk of bladder rupture, providing important protection for the patient's urinary system, and reducing the accumulation of urine, thereby reducing the possibility of urinary system infection, which is crucial for the patient's recovery, can improve the patient's quality of life and comfort, and reduce the pain and medical expenses caused by infection;

[0019] 2. The present application sets a spiral catheter structure to guide urine to form a spiral flow. This flow mode makes the urine more evenly distributed during discharge and reduces the risk of impurity deposition caused by local flow rate differences. Compared with traditional linear flow, the spiral flow can make it more difficult for impurities in the urine to adhere to the tube wall, thereby maintaining the patency of urination. At the same time, it can also speed up the discharge of urine, ensuring that the urine can be discharged from the patient's body in a timely and smooth manner. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-6 , the utility model provides a technical solution:

[0029] A urinary catheter with an anti-blocking structure comprises a urinary catheter head 1, a urinary catheter hole 2 is provided at the top and bottom of the urinary catheter head 1, an anti-blocking structure 3 is provided inside the urinary catheter hole 2, a spiral urinary catheter structure 4 is provided at the rear side of the urinary catheter head 1, and an air bag structure 5 is provided outside the spiral urinary catheter structure 4;

[0030] The anti-blocking structure 3 includes a filter frame 301 arranged inside the urinary catheter hole 2 , a primary filter screen 302 is arranged on the top of the filter frame 301 , a fine filter screen 303 is arranged on the bottom of the filter frame 301 , and the fine filter screen 303 is located at the bottom of the primary filter screen 302 .

[0031] In this embodiment: a filter frame 301 is arranged inside the catheter hole 2 through the anti-blocking structure 3, and the primary filter 302 on the top can intercept larger impurities such as blood clots and stone fragments, and the fine filter 303 on the bottom further filters tiny crystalline particles, etc. This double-layer filter design realizes precise filtration and greatly reduces the risk of blockage of the spiral catheter structure 4. For example, in patients undergoing urinary system surgery, it can effectively block various impurities in postoperative urine, ensure that urine is smoothly discharged from the body through the spiral catheter structure 4, avoid overfilling of the bladder, and reduce the risk of bladder rupture. At the same time, it reduces urine accumulation and reduces the possibility of urinary system infection, providing strong protection for the health of the patient's urinary system. At the same time, the spiral catheter structure 4 guides the spiral flow of urine, reduces impurity deposition, speeds up urine discharge, improves catheterization efficiency, and improves the patient's quality of life. In addition, the airbag structure 5 on the outside of the spiral catheter structure 4 can fix the position of the catheter 401 to prevent displacement or dislocation, increase stability, reduce urethral irritation and damage, reduce the risk of accidental dislocation, and improve catheterization safety.

[0032] Specifically, Figure 4 As shown, the spiral catheter structure 4 includes a catheter tube 401 connected to the rear side of the catheter head 1 , and a connecting groove is provided at the rear side of the catheter tube 401 .

[0033] Specifically, Figure 4 As shown, the interior of the urinary catheter 401 is provided with a self-cleaning coating 402, and the self-cleaning coating 402 has hydrophilicity and antibacterial properties.

[0034] Specifically, Figure 4 As shown, a spiral guide plate 403 is disposed inside the urinary catheter 401 , and the spiral guide plate 403 is located on the inner side of the self-cleaning coating 402 .

[0035] In this embodiment: the spiral guide piece 403 inside the catheter 401 guides urine to form a spiral flow, thereby reducing impurity deposition, accelerating urine discharge, and improving catheterization efficiency. At the same time, the self-cleaning coating 402 is hydrophilic, so that urine forms a uniform water film on the inner wall of the catheter 401, reducing impurity adhesion, and its antibacterial property can reduce the risk of bacterial growth and the possibility of urinary tract infection, thereby extending the use time of the catheter 401, reducing the number of replacements, and improving patient comfort.

[0036] Specifically, Figure 5 As shown, the airbag structure 5 includes an air guide tube 501 arranged outside the urinary catheter 401 , and the front side of the air guide tube 501 is connected to an airbag 502 , which is located on the front side of the surface of the urinary catheter 401 .

[0037] Specifically, Figure 5 As shown, the rear side of the top of the air guide tube 501 is connected to the air delivery tube 503, and the rear side of the air delivery tube 503 is connected to the air valve.

[0038] In this embodiment: after the air bag 502 on the outside of the urinary catheter 401 is inflated through the air guide tube 501, it can be firmly fixed in the bladder to prevent the urinary catheter 401 from shifting or falling out. The air valve can conveniently control the inflation and deflation of the air bag 502, and the operation is simple and convenient. For example, when the urinary catheter 401 needs to be replaced, the air can be deflated through the air valve and the urinary catheter 401 can be easily taken out.

[0039] Specifically, Figure 6 As shown, the left side of the air guide pipe 501 is connected to a flushing pipe 6 , and the rear side of the flushing pipe 6 is connected to a water valve 7 .

[0040] Specifically, Figure 6 As shown, a ring band 8 is arranged on the outer side of the water valve 7 , a plug cover 9 is bolted to the rear side of the ring band 8 , and the plug cover 9 is clamped in the interior of the water valve 7 .

[0041] In this embodiment: when the urinary catheter 401 shows signs of blockage, the water valve 7 is connected to the flushing device to inject a flushing liquid, such as saline, through the flushing tube 6 to flush the urinary catheter 401 to ensure smooth catheterization. During this process, the water valve 7 is convenient for controlling the inflow of the flushing liquid. The loop 8 and the plug cover 9 can effectively seal the water valve 7 when the flushing tube 6 is not in use to prevent urine leakage and external contamination.

[0042] Working principle: During use, the urinary catheter 401 is first inserted into the patient's urethra and into the bladder. Then, the air guide tube 501 in the airbag structure 5 controls the inflation of the airbag 502 through the air delivery tube 503 and the air valve, so that the urinary catheter 401 is firmly fixed in the bladder. Then, the urinary catheter hole 2 of the urinary catheter head 1 begins to collect urine, the primary filter 302 and the fine filter 303 filter the impurities in the urine, and the spiral guide plate 403 guides the urine to form a spiral flow, which speeds up the discharge speed and reduces the deposition of impurities. The self-cleaning coating 402 exerts its hydrophilic and antibacterial properties to reduce the adhesion of impurities and the growth of bacteria. Subsequently, when the catheter 401 shows signs of blockage, the water valve 7 is connected to the flushing device to inject a flushing liquid, such as saline, to flush the catheter 401 through the flushing tube 6 to remove the blockage. When the flushing tube 6 is not in use, the ring band 8 and the plug cover 9 effectively seal the water valve 7 to prevent urine leakage and external contamination. The overall synergistic effect of various parts provides patients with a safer, more efficient and comfortable catheterization solution.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
