Abstract
A device to protect against accidental exposure to the needle on a hypodermic syringe. A flexible tubular covering is attached to the syringe surrounding the needle and extending beyond the tip of the needle. A cap is mounted on the end of the tubular covering to enclose the needle tip. An orifice extends through the cap such that as the cap is retracted towards the syringe, the tubular covering is flexed allowing the needle to pass through the orifice in the cap.
