The safety needle system includes a safety mechanism for a needle assembly such as a Hoover needle. The main body has a channel having a proximal end for enclosing the tube and a distal end for positioning the needle nearby. The main body further includes a first hinge mechanism and a first latch mechanism. The movable cover includes a needle receptacle, a second hinge mechanism connected to the first hinge mechanism of the main body, and a bias member for pivoting the movable cover around the first and second hinge mechanisms in relation to the main body. And have. The movable cover has a second latch mechanism for latching with the first latch mechanism in the closed position, in which the safety mechanism can be disconnected from the needle and slidable away from the needle along the tube. . The movable cover has a release mechanism that allows the movable cover to pivot about the hinge mechanism so that the needle receptacle of the movable cover at least partially receives the needle of the needle assembly in the open locked position.
