Abstract
A medical device includes a hollow needle for piercing the skin of a patient. Prior to use, the needle is located in a needle protected position within a housing. The needle can be moved outwardly from the needle protected position to an extended position where it is ready for use with the patient. After use, the needle is retracted back into the housing to the needle protected position. A door is positioned at the distal end of the housing and has an aperture. The door is slidable between a first position where the needle is in alignment with the aperture in the door so that the needle can pass through the aperture to be moved to its extended position and a second position where the needle does not line up with the aperture and thus the needle cannot be moved from the needle protected position to the needle extended position.
