摘要：
A safety needle system operable with a medical device includes: a housing with a needle mount having a needle； and a sheath telescopically engaged with the housing and surrounding the needle such that the sheath operates in a retracted position, in which the sheath exposes the needle, and an extended position, in which the sheath surrounds the needle. The sheath is coupleable to the medical device such that removal of the needle from the medical device draws the sheath over the needle, transitioning the sheath from the retracted position to the extended position. In one embodiment, the system includes a slider engaged with the sheath and/or housing and including a restraint that engages and disengages the sheath to respectively reinforce and weaken the coupling of the sheath and medical device. In another embodiment, the sheath includes a longitudinal track that slidingly engages a setting of the housing between sheath positions.
