Catheter assembly support device, systems, and methods

A support device to support a catheter assembly, the support device comprising:

• a platform having an upper surface and a bottom surface, wherein the bottom surface is configured to contact skin of a patient, wherein at least a portion of the upper surface is configured to support a catheter assembly;
• an extension element coupled to the upper surface of the platform, wherein the extension element comprises:
• a distal end, comprising a first connector configured to couple to the catheter assembly;
• a proximal end, comprising a second connector;
• and
• a valve disposed between the distal end and the proximal end, wherein the valve is movable between a first position and a second position;
• and
• a cannula extending distally from the distal end of the extension element and secured within the extension element,
• wherein in response to the valve being moved to the first position, a fluid pathway extending through the cannula and the extension element is open and straight, wherein in response to the valve being moved to the second position, the fluid pathway is closed, wherein the valve comprises a socket and an arm, wherein the arm comprises a distal end, a proximal end, and a lumen extending through the distal end of the arm and the proximal end of the arm, wherein the distal end of the arm comprises a ball portion configured to rotate within the socket, wherein the proximal end of the arm comprises the second connector.
