1. An insertion device, comprising:
a housing, comprising:
a needle including a distal notch in a sidewall of the needle, the distal notch proximate a distal end of the needle, and a pair of proximal notches in the sidewall of the needle proximate a proximal end of the needle, wherein the distal notch and the pair of proximal notches are in fluid communication with a lumen of the needle;
a flash chamber enclosing the pair of proximal notches; and
a needle hub including a slot for receiving a proximal portion of the needle and the flash chamber; and
a catheter assembly, comprising:
a catheter including a catheter hub coupled to a proximal end of a catheter tube, the catheter hub including a valve and an annular ridge defined on an inner surface of the catheter hub proximal of the valve; and
a fluid control component disposed in the catheter hub, the fluid control component movable between a first position and a second position, the fluid control component including a plurality of longitudinal ribs spaced apart on an exterior surface of the fluid control component, each of the plurality of longitudinal ribs extending from a proximal end of the fluid control component to a distal end of the fluid control component, each of the plurality of longitudinal ribs comprising:
a notch at an intermediate portion between the proximal end and the distal end, the notch configured to engage the annular ridge in the first position; and
a protrusion at the proximal end configured to engage the annular ridge in the second position.
