A needle cover device comprising:
- a base having a rectangular shape and a connecting feature, the connecting feature configured to removably interdigitate with a feature of a needle hub;
- and,
- a two-piece hinged cap connected to the base by two living hinges, the two-piece hinged cap having a proximal surface and a distal surface, the two-piece hinged cap having a rectangular medial portion forming a cavity configured to enclose at least the needle hub within, each of the two-piece hinged cap having a rectangular medial portion and a lateral portion, the medial portion having a rectangular cavity formed on the distal surface configured to accommodate the needle hub, and the lateral portion having a cavity configured to accommodate a needle cannula.
A method of covering a spinal-introducer needle assembly comprising the steps of:
- sliding a foldable needle cover in a medial direction relative to a syringe assembly over a spinal-introducer needle assembly;
- withdrawing the spinal-introducer needle assembly and syringe assembly while the foldable needle cover is attached to the spinal-introducer needle assembly;
- and,
- closing the foldable needle cover over the spinal-introducer needle assembly.
