ABSTRACT:
The catheter insertion device of the present invention includes a catheter dispenser having a catheter outlet extending from a base and a drum receptacle engaged to the base in a rotating relationship. An inlet opening in the base is coaxially aligned with the catheter outlet. A passageway extends from the inlet opening tangentially through the catheter drum to the catheter outlet. A rigid needle is disposed through the passageway so that the sharp tip extends beyond the catheter outlet. A flexible introducer catheter generally contiguously and telescopically surrounds the distal portion of the needle. The introducer catheter extends beyond the catheter outlet to a position on the needle that is proximate to the sharp tip and is operatively associated with the needle for insertion into the vein of a patient. A one way flow valve is in fluid-tight connection with the proximal end of the flexible introducer catheter. The valve forms a portion of the passageway so that when the needle is slidably removed from the passageway the valve minimizes the fluid backflow from the vein. When the catheter drum is rotated relative to the base, the drum catheter is threadably inserted into and through the one way valve, through the indwelling flexible introducer catheter and into the vein of the patient.
