Abstract

A guidewire delivery device may include a housing that may include a distal end, a proximal end, a lumen extending through the distal end of the housing and the proximal end of the housing, and a slot disposed between the distal end of the housing and the proximal end of the housing. The tab is movable relative to the slot. The guidewire delivery device may include a puncture cannula coupled to the tab and extending in a distal direction. The guidewire delivery device may include an adapter proximal to and in fluid communication with the puncture cannula.

Description

technical field [0001] The present disclosure generally relates to a blood collection device and related devices, systems, and methods. In particular, the present disclosure relates to guidewire delivery devices and related devices, systems and methods. Background technique [0002] Catheters are often used to inject fluids into a patient's vasculature. For example, catheters can be used for the infusion of physiological saline solutions, various drugs, or total parenteral nutrition. [0003] Catheters may include peripheral intravenous ("IV") catheters. In this case, the catheter can be mounted on a guide needle with a sharp distal tip. The catheter and guide needle may be assembled such that the distal tip of the guide needle extends beyond the distal tip of the catheter with the bevel of the needle facing upward away from the patient's skin. Catheters and guide needles are typically inserted through the skin at a small angle into the patient's vasculature. [0004] T...
