1. An access system, comprising:
a hub, comprising a distal end, a proximal end, a lumen extending through the distal end and the proximal end;
a needle protection device to shield a sharp distal tip of a needle, the needle protection device comprising:
a housing disposed within the lumen of the hub, wherein the housing comprises a tubular portion, a first arm, and a second arm, wherein the first arm comprises a first end coupled to the tubular portion, a second end disposed within the tubular portion, and a first bent portion disposed between the first end of the first arm and the second end of the first arm, wherein the second arm comprises a first end coupled to the tubular portion, a second end disposed within the tubular portion, and a second bent portion disposed between the first end of the second arm and the second end of the second arm, wherein the second end of the first arm and the second end of the second arm form a duckbill valve, wherein the first bent portion and the second bent portion protrude further outwardly from a longitudinal axis of the housing than the tubular portion when the duckbill valve is closed and are proximate the second end of the first arm and the second end of the second arm forming the duckbill valve; and
a needle, comprising a sharp distal tip, wherein the needle extends through the housing and biases the first arm and the second arm outwardly towards the hub to facilitate retention of the housing within the hub, wherein in response to the sharp distal tip being withdrawn in a proximal direction beyond the second end of the first arm and the second end of the second arm, the duckbill valve closes and the first arm and the second arm move inwardly to facilitate removal of the housing from the hub,
wherein the tubular portion comprises a distal end and a proximal end, wherein the first end of the first arm is formed by a first slit and a second slit within the tubular portion, wherein the first end of the second arm is formed by a third slit and a fourth slit within the tubular portion, wherein the first slit, the second slit, the third slit, and the fourth slit extend through the distal end of the tubular portion, wherein the first slit, the second slit, the third slit, and the fourth slit extend along a portion of an entire length of the tubular portion such that proximal ends of the first slit, the second slit, the third slit, and the fourth slit are spaced apart from the proximal end of the tubular portion.
