TECHNICAL FIELD
[0001] The utility model relates to the technical field of catheter, specifically is urinary dual -purpose contrast catheter. BACKGROUND
[0002] The catheter mainly comprises a catheter and a catheter bag. The catheter is an elongated tubular device, one end of which is inserted into the urinary bladder, and the other end is connected to the catheter bag. The catheter bag is a container for collecting the discharged urine, and has a discharge port for periodically emptying its contents. However, the existing catheter has a single function, and the insertion of the catheter will affect the injection of contrast medium during the contrast examination. In the case of catheter replacement, such as patients with urethral stenosis or stricture, the catheter is difficult to insert again, making it inconvenient to replace. Therefore, a urinary dual-purpose contrast catheter is needed to solve the above problems. SUMMARY
[0003] The utility model discloses a urinary dual-purpose contrast catheter, which solves the problems in the background art.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: urinary dual-purpose contrast catheter, including catheter, air bag, pipe body, water injection pipe, first sealing cover, connecting end, auxiliary side pipe, top end opening one and second sealing cover, the connecting end fixedly connected in the tail end of the pipe body, the water injection pipe fixedly connected in the bottom side end of the pipe body, the auxiliary side pipe fixedly connected in the bottom end of the pipe body another side end, the first sealing cover is clamped and fixed on the water injection pipe, the second sealing cover is clamped and fixed on the auxiliary side pipe, the air bag is arranged in the inside of one end of the pipe body away from the connecting end, the catheter is set up in the front end of the pipe body, top end opening one is set up on the tip of the pipe body.
[0005] Preferably, the inside of the pipe body and the auxiliary side pipe is provided with a ureteral catheter.
[0006] Preferably, the front end of the ureteral catheter is provided with top end opening two.
[0007] Preferably, the water injection pipe is communicated with the air bag.
[0008] Preferably, the connecting end is communicated with the catheter.
[0009] Preferably, the auxiliary side pipe is communicated with the top end opening one.
[0010] Compared with the prior art, the utility model has the beneficial effects as follows:
[0011] This utility model of a urinary catheter device has a dual purpose in the urinary system, combining the functions of a ureteral catheter and a urinary catheter, and can also be used for contrast imaging. The ureteral catheter can be moved up and down. An auxiliary side tube is added next to the double-lumen catheter for the ureteral catheter to enter and exit. The outlet of this auxiliary side tube is located at the tip of the catheter, i.e., the tip opening, transforming the traditional double-lumen catheter device into a triple-lumen catheter device. The ureteral catheter can be pulled out within the separate additional lumen. Once the length of the ureteral catheter is fixed, excess material can be used to connect it to a connector. A second sealing cap is provided next to the lumen, with the connector inside. Pressing the second sealing cap closes the device. Therefore, when the ureteral catheter is not in use, it can be withdrawn and the port of the auxiliary side tube closed. The catheter remains functional. If inserted directly, for patients who do not require contrast administration, the contrast tube can be withdrawn while the catheter remains in place. For patients requiring contrast administration, cystoscopy is unnecessary; the contrast tube can be pushed directly through the lower channel of the catheter. Furthermore, when the catheter needs replacement, if the patient has urethral stricture or obstruction, reinsertion of the catheter is not required under direct cystoscopic visualization. The catheter can be successfully reinserted through this channel and the guiding effect of the ureteral catheter. When using traditional ureteral catheters, the single catheter is too thin and lacks lower fixation, making female patients prone to urinary leakage. This device can solve the problem of urinary leakage in female patients using ureteral catheters. Attached Figure Description

[0016] 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.
[0017] Please see Figure 1 , Figure 2 andFigure 3 This utility model provides an embodiment of a dual-purpose urinary contrast catheter, comprising a catheter port 1, a balloon 2, a tube body 3, an injection tube 4, a first sealing cap 5, a connecting end 6, an auxiliary side tube 7, a top opening 9, and a second sealing cap 10. The connecting end 6 is fixedly connected to the end of the tube body 3, the injection tube 4 is fixedly connected to the bottom side of the tube body 3, the auxiliary side tube 7 is fixedly connected to the other side of the bottom of the tube body 3, the first sealing cap 5 is securely mounted on the injection tube 4, the second sealing cap 10 is securely mounted on the auxiliary side tube 7, the balloon 2 is located inside the end of the tube body 3 opposite to the connecting end 6, the catheter port 1 is located at the front end of the tube body 3, and the top opening 9 is located at the end of the tube body 3.
[0018] A ureteral catheter 8 is inserted inside the tube body 3 and the auxiliary side tube 7. The ureteral catheter 8 has a tip opening 2 at the front end to facilitate the injection of contrast agent.
[0019] The water injection tube 4 is connected to the airbag 2, the connecting end 6 is connected to the urinary catheter 1, and the auxiliary side tube 7 is connected to the top opening 9.
[0020] Working principle: The catheter body 3 is inserted into the bladder through the urethral opening. After insertion, check the patency of the catheter and secure it properly to the inner thigh or waist to prevent dislodgement or displacement. Once the catheter body 3 is confirmed to be in the bladder, inject an appropriate amount of saline solution into the balloon 2 through the injection tube 4 to secure the catheter. The connecting end 6 is connected to the catheter bag to collect urine. Urine flows through the catheter port 1 into the catheter bag connected to the connecting end 6. During catheterization, the first sealing cap 5 and the second sealing cap 10 seal the injection tube 4 and the auxiliary side tube 7 tightly. For the sealing treatment, when contrast agent injection is required, the second sealing cap 10 is removed from the auxiliary side tube 7, and then the ureteral catheter 8 can be inserted into the designated position through the auxiliary side tube 7 and the top opening 9. The contrast agent can be conveniently injected through the ureteral catheter 8. When the patient has urethral stricture or obstruction and needs to replace this device, the ureteral catheter 8 is first inserted to guide the replacement device. After the replacement device is removed, the new device can be easily and conveniently inserted into the bladder through the guidance of the ureteral catheter 8.
