Abstract
A needle safety and protection device that automatically caps the used tip of a needle the instant the needle is withdrawn from the patient to protect the user against infection risks. A spiral type cut safety shield remains relaxed until the device comes in contact with the patient's skin. The safety shield attaches to the patent's skin through an adhesive component creating a tensile force once the needle is withdrawn, extending the safety disk out of its relaxed position. Under tension, the safety disk creates a cone around the needle, forming a protective shield for the needle, without any assistance by the user. The tip of the needle then engages a portion of the shield, which prevents the tip from being re-inserted into the skin of the patient or the user of the needle.
