Example Embodiment
[0050] Implementation Plan 1:
[0051] A balloon catheter with a side hole with an outer diameter of 2.0 mm and a length of 10 mm is selected, the number of through holes 7 is one, and the hole diameter is 0.1 mm. Put the balloon catheter into the silicone tube 18 to perform blood penetration performance test, slowly adjust the flow rate of the supply pump 13 so that the pressure gauge 15 indicates 13Kpa, and record the flow rate of the supply pump 13 at this time.
Example Embodiment
[0052] Implementation plan 2:
[0053] A balloon catheter with a side hole with an outer diameter of 2.0 mm and a length of 10 mm is selected, the number of through holes 7 is 2, and the aperture is 0.1 mm. Put the balloon catheter into the silicone tube 18 to perform blood penetration performance test, slowly adjust the flow rate of the supply pump 13 so that the pressure gauge 15 indicates 13Kpa, and record the flow rate of the supply pump 13 at this time.
Example Embodiment
[0054] Implementation plan 3:
[0055] A balloon catheter with a side hole with an outer diameter of 4.0 mm and a length of 10 mm is selected, the number of through holes 7 is one, and the hole diameter is 0.1 mm. Put the balloon catheter into the silicone tube 18 to perform blood penetration performance test, slowly adjust the flow rate of the supply pump 13 so that the pressure gauge 15 indicates 13Kpa, and record the flow rate of the supply pump 13 at this time.
