Description

TECHNICAL FIELD

[0001] The utility model relates to a catheter technical field, specifically a catheter connecting piece. BACKGROUND

[0002] The catheter is made of natural rubber, silicon rubber or polyvinyl chloride (PVC) and can be inserted into the urinary bladder through the urethra to drain urine. After the catheter is inserted into the urinary bladder, a balloon near the catheter head end fixes the catheter in the urinary bladder, thereby discharging urine in the urinary bladder. The catheter is connected with a catheter bag during urination.

[0003] The existing catheter is a single pipe inserted into the urinary bladder. The same pipe is used for flushing the urinary bladder, which can easily bring urine stains in the catheter into the urinary bladder, causing infection. In addition, there is no anti-reflux device at the connection between the catheter and the urine bag, and reflux can easily occur when the urine bag is accidentally squeezed. SUMMARY

[0004] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a catheter connecting piece.

[0005] To solve the above problems, the technical scheme of the utility model is as follows: a connecting pipe is provided, one end of the connecting pipe is connected with a catheter, the other end of the connecting pipe is provided with a connecting piece, the connecting piece is provided with a catheter branch pipe and a cleaning branch pipe away from one end of the connecting pipe, one end of the catheter branch pipe away from the connecting piece is provided with a urine bag connecting head, an anti-reflux valve one is arranged inside the catheter branch pipe, a flushing structure is arranged inside the cleaning branch pipe away from the connecting piece.

[0006] The cleaning branch pipe extends into the connecting pipe and is located near the liquid outlet of the catheter, an anti-reflux valve two is arranged on the side of the cleaning branch pipe near the liquid outlet hole, and a liquid leakage hole is arranged above the connection between the cleaning branch pipe and the anti-reflux valve two.

[0007] Further, one end of the connecting pipe away from the connecting piece is inserted into the catheter, and the end inserted into the catheter is a sharp structure.

[0008] Further, the flushing structure includes a mounting head one, the mounting head one is fixedly connected to the end of the cleaning branch pipe away from the connecting piece, and a liquid inlet connector is arranged inside the cleaning branch pipe.

[0009] Further, the connecting piece is made of transparent material.

[0010] The advantages of the prior art are: (1) the flushing structure is used in cooperation with the flushing branch pipe to inject the cleaning liquid of the bladder into the catheter, the cleaning branch pipe extends into the inside of the catheter main body and is located on the side close to the liquid outlet of the catheter, after the flushing liquid is sent into the catheter main body and then into the bladder through the liquid outlet of the catheter, the anti-backflow valve is used to prevent the liquid after entering the bladder from flowing back into the cleaning branch pipe to cause pollution, and the liquid flowing back from the liquid outlet of the catheter can be leaked into the catheter branch pipe through the liquid leakage hole, so that the backflow of the flushing liquid can be avoided while flushing the bladder.

[0011] (2) the anti-backflow valve is used to form a gap between the two anti-backflow valves when liquid flows out of the catheter branch pipe, and the two anti-backflow valves are closed to prevent the liquid in the urine bag from flowing back into the bladder to cause infection.
