Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a urinary catheter for compressing the prostate. Background Art

[0002] After undergoing urethral resection of the prostate, prostatectomy or radical prostatectomy, the patient needs to have a urinary catheter inserted to assist in the drainage of urine and to compress the prostate fossa or the deep dorsal venous complex of the prostate to stop bleeding.

[0003] In order to achieve compression of the prostate by the catheter, the inserted catheter needs to be pulled so that the balloon in the catheter can squeeze the prostate. However, the catheters currently available on the market require pulling the external end of the catheter when the balloon in the bladder needs to compress the prostate. At the same time, the external end of the catheter needs to be fixed to the patient's inner thigh to maintain continuous traction on the catheter, so that the balloon in the body can obtain continuous pressure. When one end of the catheter is fixed to the patient's inner thigh, the patient's movement is restricted and inconvenient, so the patient will choose to rest in bed most of the time, which increases the chance of complications such as postoperative venous thrombosis.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present application aims to provide a urinary catheter for compressing the prostate, which aims to continuously compress the prostate while solving the problem of affecting the patient's activities and improving patient acceptance.

[0006] The technical solution adopted by the present application to solve the technical problem is as follows: A urinary catheter for compressing the prostate, comprising:

[0007] A urinary catheter assembly, comprising a delivery tube, the delivery tube being inserted into the patient's body, the delivery tube having a head end close to the patient and a tail end away from the patient, the delivery tube gradually becoming thicker from the head end toward the tail end;

[0008] The compression assembly includes a compression expansion piece and a clamping ring. The compression expansion piece is sleeved on the proximal end of the delivery tube, and the clamping ring is detachably sleeved on the delivery tube and abuts against the patient's urethral opening.

[0009] Furthermore, the compression assembly further includes an adjusting member, which is mounted on the outer periphery of the clamping ring to fix the clamping ring on the delivery pipe;

[0010] The compression expansion member is a water bag or an air bag.

[0011] Furthermore, the adjusting member includes an adjusting belt and a buckle, the buckle is provided at one end of the adjusting belt, and the other end of the adjusting belt is inserted into the buckle.

[0012] Furthermore, the adjustment strap is provided with an indicator mark to indicate the length of the other end of the adjustment strap inserted into the buckle.

[0014] Furthermore, the compression assembly further includes a valve cover, and the valve cover is detachably mounted on the water injection valve.

[0015] Furthermore, the delivery tube is made of elastic material to adjust the tightness of the delivery tube.

[0016] Furthermore, one end of the delivery tube extending into the patient's body is provided with a delivery port to guide urine in the patient's body into the delivery tube.

[0017] Furthermore, a liquid outlet is provided at one end of the delivery tube away from the patient's body.

[0030] The present invention provides a urinary catheter for compressing the prostate. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention.

[0031] like Figures 1 to 4As shown, a catheter for compressing the prostate is used to compress and stop bleeding on the patient's prostate after a prostate surgery, thereby promoting rapid healing of the patient's prostate. The catheter for compressing the prostate includes a catheter component 1 and a compression component 2. The catheter component 1 includes a delivery tube 11, which extends into the patient's body. Specifically, a portion of the delivery tube 11 is located inside the patient's body, and another portion is located outside the patient's body. At this time, the delivery tube 11 has a head end for approaching the patient and a tail end away from the patient. The delivery tube gradually thickens from the head end toward the tail end. The front end of the delivery tube 11 extends into the patient's bladder and guides urine in the bladder to flow into the delivery tube 11. Finally, the urine in the bladder is discharged out of the patient's body through the delivery tube 11. The compression assembly 2 includes a compression expansion member and a clasp 22. The compression expansion member compresses the prostate. The compression expansion member expands and expands after the delivery tube 11 is inserted into the body, thereby compressing the prostate. To enable expansion after insertion, the compression expansion member is a water bag or an air bag. A water bag expands by filling it with water, while an air bag expands by filling it with air. In this embodiment, a water bag is used. The water bag 21 is mounted on the end of the delivery tube 11 that extends into the patient's body. The clasp 22 is removably mounted on the delivery tube 11, resting against the patient's urethral opening. When the front end of the delivery tube 11 is inserted into the patient's bladder, the water bag 21 also enters the patient's bladder. To limit urine discharge from the body only through the delivery tube 11, and not through the urethra connected to the bladder, the water bag 21 is filled with water, causing it to gradually expand. This allows the water bag 21 to block the connection between the bladder and the urethra, thereby forcing urine to flow only through the delivery tube 11 that penetrates the bladder, thereby controlling urine discharge through the delivery tube 11. Since the patient's prostate is also located below the connection between the bladder and the urethra, the water bag 21 can also be expanded by filling it with water, and then compressed by the water bag 21. To maintain the compression of the prostate by the water bag 21, it is necessary to pull the delivery tube 11, causing the water bag 21, which is mounted on the delivery tube 11, to move toward the patient's urethra, so that the water bag 21 continuously compresses the prostate. Therefore, in order to maintain continuous pulling on the ureter, a clamping ring 22 is provided in the present application. Specifically, when the delivery tube 11 is pulled, the clamping ring 22 is sleeved on the delivery tube 11 to clamp the delivery tube 11, preventing the delivery tube 11 from shrinking into the body under the action of the traction force, which would cause the traction force of the delivery tube 11 to disappear, and thus causing the water bag 21 to no longer compress the prostate. At this time, the clamping ring 22 clamps the delivery tube 11 and abuts against the patient's urethral opening, thereby preventing the delivery tube 11 from shrinking into the body while being clamped by the clamping ring 22. In order to improve the patient's comfort and avoid additional damage to the patient when the clamping ring 22 abuts against the patient's urethral opening, the clamping ring 22 is made of silicone material to prevent the clamping ring 22 from damaging the patient's urethral opening.In addition, the snap ring 22 is detachable, so the snap ring 22 can be reused, and can be replaced in time when the snap ring 22 is damaged.

[0032] At the same time, in order to prevent the clamping ring 22 from shifting after being put on the delivery tube 11 and causing the delivery tube 11 to continue to shrink into the body, the delivery tube 11 adopts a variable diameter design, that is, the delivery tube 11 gradually thickens from the end close to the patient to the end away from the patient, that is, the delivery tube gradually thickens from the head end to the tail end. When the clamping ring 22 abuts against the patient's urethra, due to the presence of a certain traction force on the delivery tube 11, the delivery tube 11 will drive the clamping ring 22 to move in the direction of extending into the human body, but under the obstruction of the urethra, the delivery tube 11 and the clamping ring are 22 cannot move, the clamping ring 22 will only squeeze the urethral opening, so the urethral opening will generate a reaction force on the clamping ring 22, causing the clamping ring 22 to move away from the patient. At this time, the delivery tube 11 is designed with a variable diameter. When the clamping ring 22 is just stuck on the delivery tube 11 at the urethral opening, the delivery tube 11 will gradually become thicker as it moves away from the patient. Therefore, the gradually thickening delivery tube 11 also prevents the clamping ring 22 from moving away from the patient, thereby preventing the delivery tube 11 from shrinking into the body due to the displacement of the clamping ring 22.

[0033] Furthermore, in order to be able to fix the clasp 22 on the delivery tube 11, the compression assembly 2 also includes an adjusting piece 23, which is installed on the outer periphery of the clasp 22, and the clasp 22 is fixed to the delivery tube 11 through the adjusting piece 23. Therefore, when it is necessary to use the prostate compression catheter of the present application to compress the patient's prostate, the clasp 22 is first put on the delivery tube 11, and the delivery tube 11 is inserted into the patient's body. After the insertion is completed, the water bag 21 is filled with water. After the filling is completed, the delivery tube 11 is pulled so that the delivery tube 11 has a certain traction force, and then the clasp 22 is pushed to fit with the urethral opening, and then the adjusting piece 23 is installed on the clasp 22, and the clasp 22 is fastened to the delivery tube 11 through the adjusting piece 23, thereby completing the insertion of the catheter. The delivery tube 11 will continue to remain in a pulled state under the action of the clasp 22, so that the water bag 21 continues to squeeze the prostate.

[0034] Specifically, the adjusting member 23 includes an adjusting belt 231 and a buckle 232. The buckle 232 is provided at one end of the adjusting belt 231, and the other end of the adjusting belt 231 is inserted into the buckle 232. When the clamping ring 22 needs to be fixed to the conveying pipe 11 through the adjusting member 23, the adjusting belt 231 is first wound around the outer ring of the clamping ring 22, and then the other end of the adjusting belt 231 is inserted into the buckle 232. The inner diameter of the adjusting member 23 is gradually reduced by pulling the adjusting belt 231, so that the clamping ring 22 is gradually fixed. It is fixed on the conveying pipe 11. When it is necessary to loosen the adjusting member 23 and gradually increase the inner diameter of the adjusting member 23, press the buckle 232 to release the fixation of the buckle 232 on the adjusting belt 231, and gradually push the other end of the adjusting belt 231 toward the buckle 232 to gradually increase the inner diameter of the adjusting member 23. After the adjustment is completed, the buckle 232 is no longer pressed, so that the buckle 232 re-locks the adjusting belt 231, and the adjusting belt 231 no longer moves, thereby limiting the inner diameter of the adjusting member 23. At the same time, in order to intuitively display the inner diameter of the adjusting member 23, the adjusting belt 231 is provided with an indicator mark for guiding the length of the other end of the adjusting belt 231 inserted into the buckle 232. The outer ring of the adjusting belt 231 away from the delivery tube 11 is provided with different inner diameters. When the buckle 232 moves to the position of the indicator mark, it means that the inner diameter of the adjusting member 23 at this time is the specific value displayed by the indicator mark on the adjusting belt 231. In this way, the inner diameter of the adjusting member 23 is controlled by the indicator mark to avoid the inner diameter of the adjusting member 23 being too large, which makes the clamping ring 22 unable to be fixed on the delivery tube 11 and affects the compression of the water bag 21 on the prostate. At the same time, it also avoids the inner diameter of the adjusting member 23 being too small, which makes the clamping ring 22 excessively squeeze the delivery tube 11, causing the delivery tube 11 to be blocked, affecting the patient's urination.

[0035] In order to fill the water bag 21 with water and expand it after filling with water to compress the prostate, the compression assembly 2 also includes a water injection valve 24. The water injection valve 24 is arranged next to the delivery tube 11 and is connected to the water bag 21. Therefore, when the urinary catheter in this application is inserted into the patient's body, the water injection valve 24 is connected to the water injection device, and the water injection device fills the water bag 21 with water through the water injection valve 24, thereby expanding the water bag 21 and starting to compress the prostate. At the same time, the water in the water bag 21 can be discharged through the water injection valve 24 to facilitate the subsequent removal of the urinary catheter from the patient's body. After the water bag 21 is filled with water, in order to prevent the water in the water bag 21 from flowing out, the water filling valve 24 is immediately closed after the water bag 21 is filled with water to prevent the water in the water bag 21 from leaking. At the same time, in order to further prevent the water in the water bag 21 from flowing out and causing discomfort to the patient, the compression component 2 also includes a valve cover 25. The valve cover 25 is detachably mounted on the water filling valve 24. When the water bag 21 is filled with water, the valve cover 25 is installed on the water filling valve 24 while closing the water filling valve 24. The valve cover 25 further prevents the water in the water bag 21 from flowing out of the water filling valve 24, thereby keeping the patient's body dry and preventing the water flowing out of the water filling valve 24 from wetting the patient and causing discomfort to the patient.

[0036] When the water bag 21 is filled with water, the delivery tube 11 is pulled to compress the prostate. In order to allow the delivery tube 11 to have traction after being pulled, the delivery tube 11 is made of elastic material. When the delivery tube 11 is made of elastic material, the tightness of the delivery tube 11 can be adjusted by pulling the delivery tube 11. The tighter the delivery tube 11 is, the greater the traction force of the delivery tube 11 is, thereby strengthening the compression of the prostate by the water bag 21.

[0037] Furthermore, a delivery port 12 is provided at one end of the delivery tube 11 that extends into the patient's body, through which urine in the patient's body is guided into the delivery tube 11. The delivery port 12 is provided with oblique cuts circumferentially to increase the contact area between the delivery port 12 and the urine, thereby increasing the flow rate of urine entering the delivery tube 11, thereby facilitating the discharge of urine from the patient's body. Similarly, a liquid outlet 13 is provided at one end of the delivery tube 11 that is away from the patient's body, through which urine in the delivery tube 11 is discharged. The liquid outlet 13 can be connected to a urine bag, which collects urine discharged from the delivery tube 11 for subsequent processing. In addition, a plugging member 14 is detachably mounted on the liquid outlet 13, which can be used to promptly block the liquid outlet 13 by the plugging member 14 to prevent urine from flowing out of the liquid outlet 13 when the infusion tube is not connected to a urine bag or other device for collecting and processing urine.

[0038] In addition to compressing the prostate to stop bleeding, the catheter used in this application can also compress the kidneys to stop bleeding. Because when treating stones or removing foreign bodies through PCNL (percutaneous nephrolithotomy), it is necessary to insert surgical instruments into the kidneys through puncture and insertion of sheaths, and then the surgical instruments are pulled out of the kidneys. At this time, a hole formed by the puncture and expansion will be left in the kidneys. After the surgical instruments are pulled out, there will be bleeding in the hole because there is no other structure blocking the hole. Therefore, in order to stop bleeding by compressing the hole formed by the puncture and expansion, so that the kidney can quickly stop bleeding and recover, it is necessary to insert the catheter in this application into the kidneys to stop bleeding.

[0039] Specifically, the urinary catheter is inserted into the kidney through the channel originally used to insert the surgical instrument. At this time, the delivery port 12 and the water bag 21 are inserted into the hole formed by the puncture, and the delivery tube 11 is located in the subcutaneous part of the patient. The clasp 22 is attached to the patient's skin. The clasp 22 is adjusted by the adjusting member 23 so that the clasp 22 is fixed to the skin. After the insertion is completed, the liquid outlet 13 is blocked with the blocking member 14 to prevent the blood in the kidney from flowing out of the body. Then, the valve cover 25 is opened, and water is gradually injected into the water bag 21 through the water injection valve 24, so that the volume of the water bag 21 gradually expands and compresses the hole formed by the puncture, thereby stopping the bleeding of the kidney. After a period of compression, the kidney bleeding stops. The valve cover 25 is opened to release the water in the water bag 21 through the water injection valve 24. The clasp 22 is then adjusted by the adjusting member 23 so that the clasp 22 is no longer fixed to the skin. Finally, the urinary catheter is withdrawn from the patient's body, thereby completing the hemostasis of the hole formed by the kidney puncture.

[0040] In summary, when the prostate compression catheter of the present application needs to be used to compress the patient's prostate, the clasp 22 is first put on the delivery tube 11, and then the delivery port 12 is aligned with the patient's urethral opening, and the delivery tube 11 is slowly and gradually extended into the patient's body so that the delivery port 12 and the water bag 21 all enter the patient's bladder. After the insertion is completed, the water bag 21 is filled with water through the water injection valve 24 to expand the volume of the water bag 21. After the water filling is completed, the delivery tube 11 is pulled so that the delivery tube 11 generates a certain traction force, thereby allowing the water bag 21 to compress the prostate. At the same time, the clasp 22 is slid so that the clasp 22 is abutted against the urethral opening, and then the adjusting belt 231 is installed on the outer ring of the clasp 22, and the other end of the adjusting belt 231 is inserted into the buckle 232 to adjust the inner diameter of the adjusting member 23 so that the clasp 22 is fastened to the delivery tube 11 to prevent the delivery tube 11 from shrinking into the body and causing the traction force to disappear, thereby maintaining the continuous compression of the prostate by the water bag 21.
