An intravenous catheter introducing device includes a barrel, a tubular grip member disposed to hold a needle seat in a position of use so as to permit a tip end of a needle cannula to extend forwardly of the barrel, a tubular plunger which is movable along a passage of the barrel, and a tubular receptacle which is retained in an accommodation compartment of the tubular plunger and which has socket and air-permeable ends and a flashback chamber. When the plunger is pressed forwardly to permit engagement of the socket end with a rear plug portion of the needle seat and to release the grip member from the barrel, a rearward movement of the needle seat by virtue of a biasing force of a biasing member will force the receptacle to move rearwardly so as to retract the needle cannula into the passage.
