Protective cap assembly for a needle
View Patent ↗A needle protection assembly with a cap that connects directly to a needle, thereby protecting the stem from bending. The needle protection assembly further provides a base ring for circumscribing a base portion of the needle and a bushing that interconnects the cap and the base ring, wherein there is no fixed connection between the cap and the bushing nor between the bushing and the base ring so that the bushing can rack relative to the base ring when a deflection force is imparted on the cap.
1 . A needle protection assembly, comprising:
a cap that connects directly to a stem of the needle;
a base ring circumscribing a base portion of the needle; and
a bushing that interconnects the cap and the base ring, wherein there is no fixed connection between the cap and the bushing nor between the bushing and the base ring so that a pedestal of the bushing racks relative to the base ring when a deflection force is imparted on the cap.
2 . The needle protection assembly of claim 1 , wherein the cap defines a cap lumen, wherein the bushing defines a bushing lumen, and wherein said stem is received in the bushing lumen and the cap lumen.
3 . The needle protection assembly of claim 2 , wherein the cap receives at least three-fourths of the stem.
4 . The needle protection assembly of claim 2 , wherein the cap and the bushing are elastomeric and configured to snugly engage the received stem.
5 . The needle protection assembly of claim 4 , further comprising:
the base ring has a base wall;
a sidewall perpendicularly extends from a periphery of the base wall so that an inner circumference of the sidewall defines a compartment and a first opening thereto; and
the base wall defining a second opening, opposite the first opening, to the compartment, wherein the second opening circumscribes the base portion of the needle.
6 . The needle protection assembly of claim 5 , wherein the second opening snugly engages said base portion.
7 . The needle protection assembly of claim 5 , wherein the pedestal concentrically supports the bushing, and wherein the pedestal has a pedestal diameter greater than a diameter of the bushing.
8 . The needle protection assembly of claim 7 , wherein the pedestal is seated in the compartment, whereby there is an up to one millimeter clearance between a circumferential surface of the pedestal and said inner circumference of the sidewall.
9 . The needle protection assembly of claim 8 , wherein the received stem concentrically orients the cap relative to the bushing.
10 . The needle protection assembly of claim 9 , wherein the cap is seated on the bushing.
