Description

Technical Field

[0001] The utility model relates to a urinary catheter joint for bladder flushing which is convenient for manual flushing, in particular to a urinary catheter joint for bladder flushing which is convenient for manual flushing, and belongs to the technical field of medical appliances. Background Art

[0002] Long-term indwelling catheterization is a common nursing technique in clinical practice. It is not only for observing the condition, but also a basic means for treating dysuria and caring for patients with urinary incontinence. Under normal circumstances, the urinary system is a sterile environment. When inserting a catheter, bacteria are inevitably introduced. If the aseptic technique operation principle is not strictly followed during the replacement of the catheter and urine bag, the chance of infection in the urinary system will increase. Clinically, complications such as urinary tract infection caused by the placement of a catheter are common. To prevent this from happening, nursing staff often use bladder irrigation, which is to inject a sterile liquid catheter into the bladder, so as to dilute urine, clean the bladder, and help patients eliminate bladder sediment, which is conducive to reducing urinary tract infection and urethral obstruction. The conventional method is to use the siphon principle to let the irrigation fluid flow out naturally after entering the bladder. However, the conventional indwelling catheter for patients is a double-lumen catheter with only one outlet end, and it is impossible to perform bladder irrigation according to the principle of a three-lumen catheter. To address this issue, an improved bladder irrigation method has been proposed clinically. A scalp needle is used to pierce the sterilized catheter, and the needle handle is fixed with medical tape to form a bladder irrigation pathway. Bladder irrigation is achieved by temporarily clamping the liquid outlet end of the catheter. Some patients even need to replace a three-lumen catheter to achieve long-term bladder irrigation.

[0003] The existing patented multifunctional three-way conversion joint, patent authorization number CN215961789U, constructs an improved bladder flushing device by setting a flushing port and a liquid outlet. The multifunctional three-way conversion joint has low cost and is easy to operate. The valve set in the medical three-way tube facilitates the opening and closing of the flushing fluid and the drainage fluid during bladder flushing, thereby reducing the risk of infection.

[0004] When the manual water injection pipe at the existing bladder flushing catheter joint is in use, a plug is provided at the end thereof. When manually flushing through the syringe, the plug needs to be removed and then the syringe is connected to the manual water injection pipe. After the flushing is completed, the plug needs to be installed back to prevent leakage, which is very inconvenient. Therefore, we propose a bladder flushing catheter joint that is convenient for manual flushing. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a bladder flushing catheter connector which is convenient for manual flushing.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

An injection port is opened at the end of the water injection valve pipe and is plugged and connected to the water injection end of the syringe.

[0008] A retaining ring is fixedly connected to the inner wall of the water injection valve pipe near the injection port. A sealing ball that abuts against the injection port is installed on one side of the retaining ring. Guide blocks are symmetrically installed on the outer wall of the sealing ball. Guide grooves that are slidably connected to the guide blocks are opened on the inner wall of the water injection valve pipe.

[0009] A spring is installed between the retaining ring and the sealing ball.

[0010] Preferably, a sealing rubber ring is inlaid on the inner wall of the injection port, and the sealing rubber ring abuts against the outer wall of the water injection end of the syringe.

[0011] Preferably, the length of the water injection end of the syringe is greater than the opening depth of the injection port.

[0012] Preferably, one end of the spring is connected to the retaining ring, and the other end of the spring is connected to the sealing ball.

[0013] Preferably, the axis line of the injection port and the midline of the sealing ball are on the same straight line.

[0014] Preferably, the guide block is arranged in a cylindrical structure, and the guide block and the guide groove are in clearance fit.

[0015] For a catheter connector for bladder irrigation that is convenient for manual irrigation proposed by the present utility model, the beneficial effects are as follows:

[0016] 1. The staff holds the syringe, sucks an appropriate amount of cleaning liquid inside the syringe, then conducts the water injection end of the syringe to be connected to the water injection valve pipe through the injection port. After the water injection end of the syringe is inserted into the inner side of the injection port, the sealing ball used to block the injection port is pushed open, and the spring is compressed and deformed in cooperation with the retaining ring, pushing the piston end of the syringe to push the cleaning liquid into the inner side of the water injection valve pipe. Then the syringe is removed. Under the elastic force of the spring, the guide block cooperates with the guide groove to slide, and the injection port is blocked by the sealing ball, making the manual irrigation very convenient.

[0017] 2. By using the sealing rubber ring to fill the gap at the joint between the injection port and the water injection end of the syringe, it can effectively prevent leakage during the process of injecting the cleaning liquid. Description of the Drawings
