A safety catheter includes a pivoted cam and gripping wheel within a housing. As the catheter needle is withdrawn from the catheter the needle point is captured and locked within the housing, reducing the risk of needlestick injuries. When locked, the cam prevents the needle tip from being pushed out of the bottom of the housing, and the gripping wheel prevents the needle from being pulled out of the top of the housing. The sharp needle point is automatically covered and safely contained in the housing as it is withdrawn from the catheter.
