SHARPS GUARD

摘要

An arrangement for covering the sharp point of a needle of a syringe or similar needle device. The arrangement includes a hollow cover which exposes the needle in a retracted position and covers the needle in the deployed condition. A resilient multi-section link anchored to the syringe may propel the hollow cover to the deployed position when the link or the needle device is pressed against an environmental surface. The arrangement may be integral with the needle device or may be formed as a separate component which is attachable to the needle device. An optional cap may cover the needle when the hollow cover is in the retracted position.

1. A guard for covering sharp points of needle devices and like devices for penetrating a substrate and establishing fluid communication between the needle device and the substrate for transfer of fluids therebetween, comprising:
a mount which is dimensioned and configured to engage and couple to a needle device having a needle having a longitudinal axis and terminating in a sharp point; a hollow cover for covering the sharp point of the needle, which said hollow cover is adapted to be movable between a deployed position covering the sharp point of the needle and a retracted position which leaves the sharp point of the needle sufficiently exposed to be able to penetrate the substrate; and a spring mechanism disposed to propel the hollow cover from the retracted position to the deployed position when the guard is urged against an environmental object in a direction which is out of registry with the longitudinal axis of the needle such that force is imposed on the spring mechanism.
