Abstract
The principles disclosed herein are directed toward needle safety mechanisms in which a needle is mounted in a hub, and a spring-biased safety cap is coupled to the hub. When the safety cap is released from the hub, the spring extends along the length of the needle until the cap is positioned at or beyond the end of the needle. After a needle is used for a procedure, the safety cap is extended to prevent or reduce the chance of unwanted needle sticks.
