ABSTRACT:
A unidirectional, needle outside, reel-type catheter placement unit is disclosed. The unidirectional unit obviates severing of the catheter by the needle, which can occur when the catheter is retracted in bidirectional units. Preferably, the catheter placement unit comprises an overcap or cover which is only coupled to the reel of the reel-type catheter placement unit by a ball clutch when the overcap is rotated in a direction that advances the catheter from the unit.
