Embodiment 1
[0026] Embodiment 1, when the present invention is in use, the water pump 9 pressurizes and fills the control airbag 7 for the initial expansion, and realizes positioning and fitting in the catheter head 1, and the medical staff inserts the catheter head 1 and the catheter 2 into the urethra, And the initial position makes the bending direction after expansion adapt to the direction of the curve in the urethra. The medical staff can judge whether the catheter head 1 can reach the curve according to experience and resistance. Continue to pressurize and fill the water, and the uneven axial expansion length of the control airbag 7 leads to bending, so that the attached urinary catheter head 1 follows the bending, and then can pass through the curve smoothly. After passing, the liquid is discharged to make the control airbag 7 contract and recover. After the catheter head 1 reaches the designated position in the body, the syringe 5 is used to inflate the positioning air bag 3 to re...
Embodiment 2
[0027] Embodiment 2, by controlling the communication of the syringe 5 through the control tube 14, when the syringe 5 communicates with the inflation tube 6 through a docking hole 15, the positioning airbag 3 can be inflated to make it inflated and positioned; turn the control tube 14 to disconnect The syringe 5 communicates with the inflatable tube 6, and the control tube 14 and the connecting tube 4 are rotated and sealed, and the inflatable tube 6 communicates with the docking hole 15 in a sealed state, and then the other docking hole 15 is connected to the output port of the syringe 5 , then the inside of the urinary catheter 2 is connected with the syringe 5. At this time, it is convenient to carry out work such as pumping / exhausting, liquid, etc., and when the port of the control tube 14 is sealed with a sealing cap 16, the syringe 5 can be used to extract the urinary catheter 2 The liquid inside forms a negative pressure suction.
