Abstract

A fitting for inserting a needle or catheter into a blood vessel and for positionally stabilizing the inserted needle or catheter in situ includes separate needle holder and stabilizer elements. A retainer member is secured at its proximal end to the holder and extends in spaced relation along the holder to a distal end. The stabilizer has a bi-wing shape with a slot contoured to receive the retainer member in longitudinally slidable relation at a location below a holder supporting region on the top surface of the stabilizer. The wings can be flexed upward and toward one another to positively grip the holder for insertion of the needle or catheter. When unflexed, the stabilizer slot constrains the retainer element which in turn holds the stabilizer in the space between the retainer and the holder. Removal of the needle is achieved by withdrawing the retainer longitudinally from the stabilizer slot.
