NEEDLE GUARD

摘要

A needle guard assembly having a resilient arm extending from a base situated to slide along the shaft of a needle. In one implementation the needle guard has an elongate containment member that rides with the resilient arm and is co-operable with the resilient arm to effectuate a covering of the entire distal tip of the needle upon the needle being retracted into the needle guard.

主权项

1. A needle assembly comprising: a needle having a longitudinal axis, a proximal end, and a distal tip; an elongate member disposed about the needle, the elongate member having an inner surface and an outer surface; and an axially extending arm having a radially extending distal section, wherein in a non-shielding position the radially extending distal section is biased radially inward against the outer surface of the elongate member, and wherein in a shielding position the distal tip is positioned within the elongate member, and at least a portion of the radially extending distal section extends over a distal end of the elongate member, blocking distal movement of the distal tip of the needle, the axially extending arm including a proximal section, a mid-section and a distal section, the proximal section having a first width and the distal section having a second width, the mid-section having a portion of a reduced width, the reduced width being less than one or both of the first and second widths so that an indentation is provided in a side of the axially extending arm, the axially extending arm intersecting the elongate member along the reduced width portion of the mid-section of the axially extending arm located between the proximal and distal sections.
