A sheath for a medical needle device such as a syringe or blood collection device comprises a barrel, hub, cone and shield. The needle device is guided into a visible aperture surrounded by the shield at the top of the cone for ultimate extension of the needle through the hub and into the barrel. The sheath precludes splashing of body fluids onto the user upon capping as well as accidental puncture. The barrel, hub and cone elements of the sheath provide a plurality of friction-fit engagements with the medical needle device to preclude accidental decapping and seepage of fluids from the sheathed needle and onto the user.
