Abstract
A catheter system may include a catheter adapter and a needle shield device coupled to the catheter adapter. The needle shield device may include a needle housing and a needle assembly slideably coupled to the needle housing. The needle housing may include an elongated body and a nose portion coupled to the elongated body. The elongated body may include a distal end, a proximal end, and a slot disposed between the distal end and the proximal end of the elongated body. The needle assembly may include a needle grip and a needle hub having a protuberance coupled to the needle grip and slideably fit within the slot. To facilitate securement between the catheter adapter and the needle shield device, a flexible arm of the needle shield device may couple to the catheter adapter and/or multiple protrusions of the nose portion may contact an internal wall of the catheter adapter.
