Patent

CA 2364972

An automatically shieldable blood collection set is provided. The blood collection set includes a needle assembly having a hub with inner and outer tubes. A needle cannula is fixedly attached to the inner tube. The outer tube is split longitudinal, and a first spring biases the slit into an open orientation. A safety shield is telescoped between the tubes to the hub and the needle cannula and can be moved from a proximal position where the needle cannula is exposed to a distal position where the needle cannula is safely shielded. A second spring is provided between the shield and the hub to propel the shield distally relative to the hub and into surrounding relationship with the needle cannula. However the outer tube can be biased against forces of the first spring to slit and clamp the shield in a fixed position.
