Abstract
A safety shield assembly is provided for safely enclosing a needle cannula. The safety shield assembly includes an inner shield that is slidably movable along the needle cannula. The inner shield includes a locking structure which locks the inner shield with respect to the distal end of the needle cannula. The safety shield assembly also includes an outer shield that is in releasable engagement with the inner shield. The outer shield will separate from the inner shield in response to excessive force exerted thereon, and hence avoids failure of the structure locking the inner shield to the needle cannula.
