ABSTRACT:
Protective catheter devices are disclosed including a barrel for housing a catheter including a needle extending therefrom. The catheter is slidably retained within the barrel between a fully retracted position and an extended position, in which the needle can be inserted into a patient, and the device includes a locking mechanism for controlling the position of the needle within the barrel, which includes at least two positions; namely, a first position in which the needle is freely slidable within the barrel and a second position in which the needle is locked in its retracted position within the barrel, such that the needle cannot be displaced from its retracted position without repositioning the locking mechanism.
