Abstract: A safety needle cap assembly for needles automatically caps the used needle the instant the needle is withdrawn from a patient. An elastic compressible sheath is attached to a safety needle cup shaped cap and is under compression with the cap in a retracted position exposing the needle tip for use. The cap is restrained in a rearward needle exposed state by one or more extension members extending rearwardly from the cap over the syringe hub. The extension may be a thin film, a string, a flexible rod or an articulated rod which are pressed against the hub by an outer packaging enclosure to retain the cap in the needle exposed state during shipping and handling prior to use. During removal of the enclosure for use of the needle, the extension is then pressed against the hub by the user in one embodiment, or a syringe grip or catheter body in other embodiments, holding the needle exposed ready for use.

Abstract: A safety needle cap assembly for needles is described. In place of the usual safety cap which requires a doctor, dentist or nurse to manually place it in position on a used syringe needle, the safety needle cap assembly of the invention automatically caps the used needle the instant the needle is withdrawn from the patient. An elastic sheath or spring attached to a safety needle cap is kept under tension, retracting the cap and allowing the needle tip to be exposed. Once used and removed from the patient, the elastic tension is released, causing the safety needle cap to snap over the used needle tip automatically, without any operator assistance. The design of the safety needle cap assembly as described facilitates the utilization thereof, especially where it is important to distance the operator's fingers from the point of contact of the needle with the patient's body.

Abstract: A safety needle cap assembly for needles and catheters is described. In place of the usual safety cap which requires a doctor, dentist or nurse to manually place it in position on a used syringe needle, the safety needle cap assembly of the invention automatically caps the used needle the instant the needle is withdrawn from the patient. An elastic sheath or spring attached to a safety needle cap is kept under tension, retracting the cap and allowing the needle tip to be exposed. Once used and removed from the patient, the elastic tension is released, causing the safety needle cap to snap over the used needle tip automatically, without any operator assistance. The design of the safety needle cap assembly as described includes at least needle clogging material disposed in the safety needle cap to fill the tip of the needle therewith so as to entrap the fluid contained therein. This can be combined with needle capturing material to further enhance the safety features of the assembly.

The design of the safety needle cap assembly as described virtually preclude accidental re-emergence of the used needle tip during disposal of the needle-cap assembly.
