Catheter insertion device with valve

A catheter insertion device comprising:

• a catheter dispenser having a base, a catheter outlet extending from the base, and a rotatable catheter drum rotatably mounted on the base, a catheter mounted on said rotatable catheter drum, said catheter drum constructed so that rotation of said catheter drum relative to said base moves said catheter laterally through said catheter outlet;
• an inlet opening in said catheter dispenser in coaxial alignment with said catheter outlet;
• said catheter dispenser defining a passageway extending from said inlet opening to said catheter outlet;
• a needle having a proximal end portion and a distal end portion, a sharpened tip for insertion into a vein of a patient mounted on said distal end portion, said needle constructed to slide through said passageway so that said sharpened tip extends beyond said catheter outlet;
• a flexible introducer catheter member constructed to substantially concentrically surround a portion of said distal end portion of said needle, said flexible introducer catheter member constructed to substantially concentrically surround a portion of said catheter when said drum catheter advances said catheter through said catheter outlet, a portion of said flexible introducer catheter extending beyond said catheter outlet, a one-way flow valve disposed within said flexible introducer catheter, said one-way flow valve constructed to minimize backflow of fluid through said flexible introducer catheter when said needle and said catheter are withdrawn therefrom, said one-way flow valve constructed such that said needle and said catheter are slidable therethrough, said flexible introducer catheter member further including a wiper means for substantially fluidly sealing against said flexible introducer catheter member upon disposition of said catheter through said wiper, without necessitating the imposition of axial compressive forces on said wiper in order to effect the seal, said wiper projecting radially inwardly from an interior wall of said flexible introducer catheter, said wiper means disposed within said catheter member and constructed such that said needle and said catheter are slidable therethrough.
