  • *1 Kink tolerance evaluation
    Apply compressive load to catheter inflected in a horseshoe shape.
    Monitor occurrence of kink (a point where resistance falls).
    *1
  • *2 Flow rate under severity condition
    Flow rate under severity condition.
    Pressure : 1,000mmH2O
    *2
  • *3 Catheter insertion smoothness into epidural needle
    Max resistance force is measured when the catheter passes through the curved point of the epidural needle.
    200mm/min
