Abstract
A catheter assembly may include a catheter, catheter adapter, needle, needle guard, and housing. The housing may be coupled to the needle guard and disposed within a lumen of the catheter adapter. The needle guard may include first and second resilient arms, which may include first and second curved portions, respectively. When the needle is in a ready position, the first and second curved portions may be urged by a shaft of the needle into retaining contact with an inner wall of the catheter adapter. When the needle is in the retracted position, the shaft may no longer bias the first and second resilient arms outwardly such that the retaining contact between the first and second curved portions and the catheter adapter is released, and the housing and the needle guard enclose a distal tip of the needle.
