Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and in particular relates to a urine leakage preventing indwelling urinary catheter device. Background Art

[0002] Indwelling catheterization is a common technical operation in hospital clinical practice. It is suitable for patients with acute and chronic urinary retention and urethral stenosis. The catheter is inserted into the urethra under sterile operation, and the balloon at the front end of the catheter is inflated to block the urethral opening, preventing the catheter from falling off and allowing urine to flow out of the catheter to assist the patient in urination.

[0003] Existing urinary catheters often leak urine during use due to various reasons, especially for patients with long-term indwelling catheters. For example, relaxation of the patient's urethral muscles, shaking and displacement of the catheter, etc., cause urine to flow out from the gap between the catheter and the urethra. The leaked urine can contaminate the bed sheets and irritate the patient's skin, causing complications such as incontinence dermatitis, thereby increasing the patient's pain. Therefore, to address the above problems, we have proposed a urine leakage-proof indwelling catheter device. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a urine leakage-proof indwelling catheter device, which can prevent the patient from being contaminated by urine leakage during the indwelling catheterization process and reduce the patient's discomfort.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a urine leakage-proof indwelling urinary catheter device, comprising a urinary catheter body, a urine flow hole being opened at one end of the urinary catheter body, a water bag being provided at the end of the urinary catheter body close to the urine flow hole, a drainage outlet for draining urine and a water filling port for filling the water bag being provided at the other end of the urinary catheter body, a folding tube being provided at the end of the urinary catheter body away from the urine flow hole, a urine collecting cup being provided at the movable end of the folding tube, the open end of the urine collecting cup being in contact with the external opening of the urethra, and a fixing part for fixing the urine collecting cup being provided on the urine collecting cup.

[0006] The beneficial effects of the present invention are as follows: by inserting the catheter body into the patient's body, stretching the folding tube close to the external urethral opening, and then fitting the urine collecting cup to the skin of the external urethral opening and fixing it with a fixing piece, when urine leaks, the urine will enter the urine collecting cup, preventing urine from leaking out to contaminate the bed sheets and irritate the skin, thereby reducing the patient's discomfort.

[0007] In order to fix the urine cup and effectively prevent pollution and discomfort caused by urine leakage;

[0008] As a further improvement of the above technical solution: the fixing member includes a front belt and a rear belt symmetrically arranged on the urine collecting cup, and the front belt and the rear belt are both provided with connecting belts, and the connecting belts are fixed by a connecting member.

[0009] The beneficial effect of this improvement is that when the urine collecting cup is fitted to the patient's external urethral opening, the front belt fits the patient's front, and the rear belt fits the patient's back, and by bringing the movable ends of the two connecting belts close together and then adjusting and fixing the connecting parts, the urine collecting cup is fixed to the external urethral opening, preventing urine from leaking, contaminating the bed sheets and irritating the patient's skin, causing discomfort to the patient.

[0010] To facilitate the cleaning of leaked urine;

[0011] As a further improvement of the above technical solution: a leak-proof ring band is provided on the circumferential outer wall of the urinary catheter body, and the outer wall of the leak-proof ring band is connected to the upper end of the foldable tube.

[0012] The beneficial effect of this improvement is that when the urine collecting cup is fitted onto the patient's external urethral opening, the movable end of the folding tube needs to be unfolded toward the external urethral opening. At this time, the external urethral opening drives the outer wall of the leak-proof ring band to fold toward the external urethral opening. At this time, the outer wall and the inner wall of the leak-proof ring band are close to each other, so that the leak-proof ring band forms a pocket shape. When urine leaks, the urine enters the interior of the leak-proof ring band through the urine collecting cup. When the leaked urine needs to be treated, the folding tube is contracted. At this time, the leak-proof ring band is unfolded, and the urine inside can flow out. Then the leak-proof ring band can be scrubbed and disinfected.

[0013] To facilitate the management of urine leakage;

[0014] As a further improvement of the above technical solution: a leakage ring is provided at the bottom of the urine collecting cup, and a plurality of leakage holes are opened on the leakage ring. The plurality of leakage holes are equidistantly arranged along the central axis of the leakage ring, and a water-absorbing sponge is filled between the leakage ring and the leakage-proof ring belt.

[0015] The beneficial effect of this improvement is that when the leak-proof ring belt is folded into a pocket shape, a water-absorbing sponge can be stuffed on the leak-proof ring belt. At this time, the setting of the leakage ring can limit the movement of the water-absorbing sponge, preventing the water-absorbing sponge from touching the external urethral opening and irritating the skin of the external urethral opening. Urine is completely absorbed by the water-absorbing sponge through the leakage hole, making it easy to deal with leaked urine.

[0016] To increase patient comfort;

[0017] As a further improvement of the above technical solution: the open end of the urine collecting cup is provided with a fitting ring, and the fitting ring is provided with a fitting portion.

[0018] The beneficial effects of this improvement are: the setting of the fitting ring avoids direct contact between the urine collecting cup and the skin of the external urethral opening, avoids damage to the skin of the external urethral opening, and increases the patient's comfort. In addition, the setting of the fitting part can make the urine collecting cup and the skin of the external urethral opening more closely contact.

[0019] Fold the tube for ease of use;

[0020] As a further improvement of the above technical solution: a pull ring is provided on the urine collection cup, and anti-slip patterns are provided on the pull ring.

[0021] The beneficial effect of this improvement is that the setting of the pull ring can facilitate the control of the expansion and contraction of the folding tube when the folding tube is expanded and contracted. In addition, the anti-slip patterns can increase the friction between the pull ring and the hand.

[0022] In order to achieve the flexibility and adjustable nature of the device;

[0023] As a further improvement of the above technical solution: the folding tube is a corrugated flexible tube.

[0024] The beneficial effect of this improvement is that the corrugated flexible tube can freely expand and contract and bend, so as to adapt to the urine tubes of different lengths according to individual differences, and can more conveniently adjust the position and state of the urine collection cup to achieve the best urine collection effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present utility model.

[0032] Such as Figures 1-5As shown in the figure, an anti-leakage indwelling urinary catheter device includes a urinary catheter body 1. One end of the urinary catheter body 1 is provided with a urine drainage hole 2. A water bag 3 is provided at one end of the urinary catheter body 1 near the urine drainage hole 2. The other end of the urinary catheter body 1 is provided with a drainage outlet 5 for draining urine and a water filling port 4 for filling the water bag 3. A folding tube 6 is provided at the end of the urinary catheter body 1 away from the urine drainage hole 2. A urine collection cup 7 is provided at the movable end of the folding tube 6. The opening end of the urine collection cup 7 is attached to the external urethral orifice. A fixing member is provided on the urine collection cup 7;

[0033] Specifically, after inserting the urinary catheter body 1 into the patient's urethra and into the bladder, by filling water into the water filling port 4, the airbag is filled. Then, the filled airbag blocks the urethral orifice to prevent the urinary catheter body 1 from coming out of the urethral orifice. Then, urine comes out from the drainage outlet 5 on the urinary catheter body 1 through the urine drainage hole 2. When the indwelling urinary catheter is in place for a long time, due to the relaxation of the urethral muscles and the shaking and displacement of the urinary catheter, urine may leak out. To prevent the urine from leaking out and contaminating the bedsheet and irritating the patient's skin, after inserting the urinary catheter body 1, move the movable end of the folding tube 6 towards the direction of the external urethral orifice. Then, bring the urine collection cup 7 close to the external urethral orifice and attach it to the skin of the external urethral orifice. Then, fix it through the fixing member to prevent the urine collection cup 7 from shifting. After the urine leaks out, it directly enters the urine collection cup 7, avoiding the urine from flowing out and contaminating the bedsheet and irritating the patient's skin, and reducing the discomfort of the patient caused by urine leakage.

[0034] Preferably, the fixing member includes a front belt 801 and a rear belt 802 symmetrically arranged on the urine collection cup 7. Connecting belts 17 are provided on both the front belt 801 and the rear belt 802. The connecting belts 17 are fixed by a connecting member 9. The connecting member 9 can be a structure such as a magic tape or a snap fastener. When the urine collection cup 7 is attached to the patient's external urethral orifice, the front belt 801 is attached to the front of the patient, and the rear belt 802 is attached to the rear of the patient. By bringing the movable ends of the two connecting belts 17 close, and then adjusting and fixing them with the connecting member 9, the urine collection cup 7 is fixed at the external urethral orifice to prevent urine from leaking out, contaminating the bedsheet and irritating the patient's skin, causing discomfort to the patient.

[0035] The foldable tube 6 is provided with a leak-proof ring band 10 on the outer circumferential wall of the urinary catheter body 1, and the outer wall of the leak-proof ring band 10 is connected to the upper end of the foldable tube 6, wherein the leak-proof ring band 10 can be waterproof nylon cloth, waterproof Oxford cloth, etc. When the urine collecting cup 7 is fitted with the patient's urethral external opening, the movable end of the foldable tube 6 needs to be unfolded toward the urethral external opening. At this time, the urethral external opening drives the outer wall of the leak-proof ring band 10 to fold toward the urethral external opening. At this time, the outer wall and the inner wall of the leak-proof ring band 10 are close to each other, so that the leak-proof ring band 10 forms a pocket shape. After urine leaks, urine enters the interior of the leak-proof ring band 10 through the urine collecting cup 7. When the leaked urine needs to be treated, the foldable tube 6 is retracted. At this time, the leak-proof ring band 10 is unfolded, and the urine inside can flow out. Then the leak-proof ring band 10 can be scrubbed and disinfected. Compared with some existing technologies that drain urine into another urine collection bag through a connecting tube, the use of consumables is reduced, which has a certain economic effect.

[0036] Preferably, a leakage ring 12 is provided at the bottom of the urine collecting cup 7, and a plurality of leakage holes 11 are opened on the leakage ring 12. The plurality of leakage holes 11 are equidistantly arranged along the central axis of the leakage ring 12, and a water-absorbing sponge 13 is filled between the leakage ring 12 and the leakage-proof ring belt 10. When the leakage-proof ring belt 10 is folded into a pocket shape, the water-absorbing sponge 13 can be filled on the leakage-proof ring belt 10. At this time, the setting of the leakage ring 12 can limit the movement of the water-absorbing sponge 13 to prevent the water-absorbing sponge 13 from touching the external urethral opening and irritating the skin of the external urethral opening. Urine is completely absorbed by the water-absorbing sponge 13 through the leakage holes 11, which is convenient for handling leaked urine.

[0037] Preferably, a fitting ring 14 is provided at the open end of the urine collecting cup 7, and a fitting portion 15 is provided on the fitting ring 14, wherein the fitting ring 14 can be made of a flexible material such as rubber or silicone. The setting of the fitting ring 14 avoids direct contact between the urine collecting cup 7 and the skin of the external urethra, avoids damaging the skin of the external urethra, and increases the patient's comfort. In addition, the setting of the fitting portion 15 can make the urine collecting cup 7 more closely contact with the skin of the external urethra. The fitting portion 15 is a downwardly concave arc, which can enhance the stability and fit of the urine collecting cup 7 and reduce the risk of urine leakage.

[0038] Preferably, a pull ring 16 is provided on the urine collecting cup 7, and the pull ring 16 is provided with anti-slip grooves. The setting of the pull ring 16 can facilitate the control of the expansion and contraction of the folding tube 6 when the folding tube 6 is expanded and contracted. In addition, the anti-slip grooves can increase the friction between the pull ring 16 and the hand.

[0039] Preferably, the folding tube 6 is a corrugated hose, which can be freely expanded and bent, so as to adapt to different lengths of the urinary catheter body 1 according to individual differences, and can more conveniently adjust the position and state of the urine cup 7 to achieve the best urine collection effect.

[0040] The working principle and use process of the present invention are as follows: when using the device, the catheter body 1 needs to be inserted into the urethra and into the bladder first, and the air bag is filled by filling the water filling port 4 with water, and then the filled air bag blocks the urethral opening to prevent the catheter body 1 from coming out of the urethral opening, and then urine comes out of the drainage port 5 on the catheter body 1 through the urine flow hole 2, and the pull ring 16 is pulled by hand. At this time, the pull ring 16 drives the movable end of the folding tube 6 to move toward the external urethral opening, and then the urine collecting cup 7 is brought close to the external urethral opening and contacts with the external urethral opening. At this time, the fitting part 15 on the fitting ring 14 fits with the skin of the patient's external urethral opening, and at the same time, when the movable end of the folding tube 6 moves toward the external urethral opening, the folding tube 6 drives the leak-proof ring belt 10 to bend, so that the leak-proof ring belt 10 can bend. The annular belt 10 is formed into a pocket shape, and then the absorbent sponge 13 is stuffed onto the leak-proof annular belt 10. At this time, the leakage ring 12 limits the absorbent sponge 13. Then the front belt 801 is fitted to the front of the patient, and the rear belt 802 is fitted to the back of the patient. Then the two connecting belts 17 are wrapped around the patient's waist and fixed through the connecting piece 9. When the patient leaks urine, the leaked urine enters the absorbent sponge 13 on the leak-proof annular belt 10 through the urine collecting cup 7 and is absorbed by the absorbent sponge 13. When treatment is needed, the folding tube 6 is contracted to unfold the leak-proof annular belt 10, and the absorbent sponge 13 is taken out and replaced. During use, the utility model enables the patient to avoid contamination caused by urine leakage during the process of indwelling urinary catheterization and reduces the patient's discomfort.
