Summary: | The invention relates generally to an improved catheter insertion device of the type having a drum-like receptacle which advances the catheter when it is rotated relative to the base, causing the catheter to move through a tubular outlet. The improvement comprises a removable needle which extends coaxially through a tubular housing tangentially affixed to the dispenser. A flexible cannula telescopically surrounds the distal portion of the needle. The cannula is connected to a catheter outlet from the receptacle and is adapted to be inserted into the vein of a patient during venipuncture. Once venipuncture is performed, the needle is slidably removed from the cannula and catheter outlet, and the catheter is telescopically inserted into and through the cannula and thereby into the vein of the patient. The base and receptacle may then be easily separated and removed from the catheter. |
