Abstract
A needle stick protection device includes a housing shaped and dimensioned for positioning about a needle. The housing includes a first housing member telescopically coupled to a second housing member. The first housing member includes an open first end and an open second end. The second housing member includes an open first end and a substantially closed second end, the second end including an aperture shaped and dimensioned to permit the passage of a needle therethrough. The device also includes a mechanism for locking the first housing member relative to the second housing member wherein the second housing member moves relative to the first housing member to facilitate retraction and extension of the needle through the aperture at the second end of the second housing member. The second housing member is biased relative to the first housing member in a manner forcing the first end of the second housing member away from the first end of the first housing member to maintain the second housing member in a cover position in which the needle is fully contained within the housing.
