Abstract
The invention relates to an access device comprising: a base () for aligning the access device with the skin of a patient; a needle for puncturing the skin, the needle comprising a hub () and a cannula (), and the needle being movably mounted in the base () such that it can move between a first, fully retracted, and a second, maximally extended, position; and a locking mechanism which engages when the needle retracts from the second position and reaches a discrete third position, inhibiting the needle from further retracting to the first position. According to the invention, the access device is actuatable to disengage the locking mechanism.
