Title:
Safety device for a needle having two sharpened ends
Document Type and Number:
WIPO Patent Application WO2001032231
Kind Code:
A3
Abstract:
A safety device for a phlebotomy needle having two sharpened tips, a forward or distal tip which is used for percutaneous sampling and a rear or proximal tip which is used to penetrate vacuum sampling tube stoppers. The phlebotomy needle safety device has a needle shield disposed about the rear or proximal needle, which is displaced only by the standard action of threadably connecting the device to a phlebotomy barrel, to permit penetration of vacuum sampling tube stoppers. The device also has a retractable and extendable, protective medical needle shield which provides opportunity for accessing and reaccessing a forward or distal needle and associated sharpened needle tip and recovering the needle and tip for safety between accesses. The shield includes a needle guide which assures the forward needle tip is untouched by any part of the shield as the shield is displaced to cover and uncover the needle.
