[0002] When draining urine, it is usually necessary to connect a drainage tube to a urinary catheter. However, during the drainage process, it is necessary to monitor the intra-abdominal pressure, so a three-way valve needs to be connected in series on the drainage tube.

[0003] As shown in the attached Figure 1 figure, the inlet of the three-way valve 1 is connected to the urinary drainage tube 2, the first outlet of the three-way valve 1 is connected to the monitoring tube 3, and the second outlet of the three-way valve 1 is connected to the urine collection drainage tube 4. However, in the actual operation process, the diameter of the second outlet of the three-way valve 1 does not match the diameter of the urine collection drainage tube 4. Therefore, a method was thought of to connect the second outlet of the three-way valve 1 to the urine collection drainage tube 4 through the syringe barrel 6. However, this method not only consumes syringes, but also the assembly process is relatively troublesome and it is easy to fall off after connection. Content of the Utility Model
