Abstract:
A needle device, comprising:a housing having a pair of wings, a first end with a first opening and a second end with a second opening; a needle assembly having a needle attached to a needle hub slidably fitted within said housing, the needle extendable through said first opening and said needle hub passable through said second opening; a bias element inside said housing for applying a biasing force against said needle hub towards said second end; a key movably fitted to said housing at a first placement along a plane orthogonal to the longitudinal axis of said housing for maintaining said needle assembly in a first position relative to said housing whereby the needle is extended out of said first opening, said key actuable to a second placement along said plane orthogonal to the longitudinal axis of said housing to allow the needle to be retracted into said housing due to said needle assembly being biased by said bias means; and a safety lock element coacting with said key and ordinarily acting against a portion of said housing to prevent inadvertent actuation of said key from said first placement to said second placement.
