Abstract
A safety shield apparatus is provided that includes a housing that defines a cavity. A distal end of the housing includes a cover having a movable tab. A hub is disposed for movement within the housing and includes a needle having a distal end and a movable projection. The hub is biased between an extended position, such that the distal end of the needle is exposed and the movable projection is releasably disposed with the cavity, and a retracted position whereby the distal end of the needle is disposed within the housing. The movable tab is engageable with the movable projection to release the movable projection from the cavity to facilitate movement of the hub. The distal end of the housing may define a lip that is configured to capture the distal end of the needle. The hub can define an angled distal surface to orient the needle out of axial alignment with the housing and into capture with the lip.
