摘要：
A needle shield device may include a needle housing and a needle assembly slideably coupled to the needle housing. The needle housing may include a nose portion configured to be inserted into a catheter adapter and an elongated body having a distal end, a proximal end, and a slot disposed between the distal end and the proximal end of the elongated body. A distal portion of the slot may be sealed to prevent blood from leaking out of the needle housing. The needle assembly may include a needle grip, an introducer needle having a sharp distal tip and a proximal end, and a needle hub having a protuberance coupled to the needle grip and slideably fit within the slot. In response to movement of the needle assembly to a proximal position with respect to the needle housing, the sharp distal tip may be disposed within the needle housing.
