The present invention contemplates an improved syringe device with retractable needle, and a method of delivering fluid to a patient and retracting the needle within the syringe after the fluid is delivered. The syringe preferably includes a hollow plunger inserted into one end of a cylindrical barrel and a hollow needle attached to the other end of the barrel. Biasing means is attached to the barrel for biasing the needle toward the hollow plunger, and means is provided for releasing the needle into the hollow plunger by applying additional forward pressure upon the plunger after the plunger is fully extended into the barrel. The present invention is particularly convenient for the operator to use in a one-handed fashion and is relatively uncomplicated and easy to manufacture.
