Abstract:
1. An over-the-needle catheter assembly comprising: an adapter; a needle having a diameter and a distal tip, slidingly disposed within the adapter; a needle shield assembly slidably mounted on the needle, wherein the needle shield assembly has an open distal end and an open proximal end through which the needle passes; a plurality of canting plates disposed within the needle shield assembly and having an unactivated first position and an activated second position for restricting distal needle movement; and whereby an elastomeric member compressed between the canting plates for exerting a continuous biasing force on the canting plates while the canting plates are in the unactivated first position; and wherein the canting plates are responsive to proximal movement of the needle, such that when the needle tip is housed within the needle shield assembly, the canting plates are actuated, allowing movement of the canting plates from the unactivated first position to the activated second position, wherein the elastomeric member is a washer.
