Abstract: The invention consists of a unit 10 including a two-piece, snap together housing made of elements 40 and 50 which forms the orifice seat and the transitions which direct moisture away from the seat area and prevents the accumulation of moisture in the seat area. Left-Hand (LH) housing 50 contains a blind journal and right-hand (RH) housing portion 40 contains a through journal for support and location of the gate 60. Also integral to the RH housing portion 40 are bosses for attaching the snap action switches 80, which determine gate orientation and mounting a gear motor 90, and can generally be referenced as “gate position sensors”. Such switches could also be replaced with other gate position sensors such as know in the art such as hall effect switches, magnetic switches, optical devices, etc. The gear motor provides the driving torque to the gate 60 through a cam-coupling 70, which has four switch detents 71, oriented to an internal shaft indexing means.

Abstract: A safety package (54) for preventing accidental skin pricking by a hypodermic syringe type needle (16) having a needle hub (14) joining the needle (16) to the syringe (18) and comprising a first tubular section (12) securable at its first end to the needle hub (14). A second tubular section (54) is secured at a first end to a hinge (56) and surrounds the needle (16) in a first position (FIG. 1) with a longitudinal slot (58) formed therein and positioned to pivot about the hinge (56) and away from the needle (16) to a second position (FIG. 2) with the needle (16) passing through the longitudinal slot (58, FIG. 3) to expose the needle (16) for use and, after use of the needle, to pivot the second tubular section (54) back to its first position.
