Bi-directional clamping guard for needle stick protection

摘要: A needle stick protecting device slideably mounted over medical needles having pointed tips, comprising at least two clamping members sliding the shaft and joined together their proximal end, automatically arresting in proximity of tip upon passage triggerng means beyond tip, said triggering projecting toward from members. Said member on is bi-directional, as it occurring both response to application a force for forward guard applied withdraw tip. Another relevant feature negligible friction opposed by motion, being variable proportionally dependent motion.
