Abstract: A blood draw system may include a catheter adapter connector in fluid communication with a catheter adapter, and a blood draw device in selective fluid communication with the catheter adapter connector. A first valve may be utilized to selectively permit fluid communication between the blood draw device and the catheter adapter connector. A flush device may also be in selective fluid communication with the catheter adapter connector to flush the catheter adapter after a blood draw procedure. A second valve may be utilized to selectively permit fluid communication between the flush device and the catheter adapter connector.

Abstract: An insert for a catheter system may include a distal end, a proximal end, and a middle portion disposed between the distal end and the proximal end. The distal end of the insert may include a male port, and the proximal end of the insert may include a female port opposite the male port. The insert may be configured to extend through an adapter and/or a needleless connector of a catheter system to reduce exposure of the adapter and/or the needleless connector to blood, which may flow through a lumen of the insert. The lumen of the insert may extend through the male port, the middle portion, and the female port.

Abstract: A vascular access system which may be configured for blood draw may include a housing, which may include a distal end, a proximal end, and a slot disposed between the distal end and the proximal end. The slot may include a notch. The vascular access system may include a cannula hub, which may be disposed within the housing and movable with respect to the slot. The cannula hub may include a tab extending through the slot. The vascular access system may include a cannula extending distally from the cannula hub. In response to the tab being disposed within the notch, a distal tip of the cannula may be disposed within the housing. In response to advancing the tab along the slot to a distal end of the slot, the distal tip of the cannula is disposed distal to the distal end of the housing.

Abstract: A guidewire delivery device may include a housing, which 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 may be moveable with respect to the slot. The guidewire delivery device may include a penetration 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 penetration cannula.
