ABSTRACT:
The invention is a new and unique device much needed to protect the health care providers from the leading cause of exposure to blood born diseases in their profession, this being inadvertent needle sticks by contaminated needles. Dirty needle stick accidents are one of the major means in which health care providers are exposed to the HIV virus on the job. The invention is a blunt tubular stylet that is inserted into the commonly used intravenous therapy device. Initially it is positioned inside the needle stylet in a retracted position, by means of the friction catches. This allows the cutting tip of the existing intravenous therapy device's cutting tip to be exposed. Upon successful venipuncture the invention is positioned so its blunt tubular stylet is advanced beyond the intravenous therapy venipuncture device's cutting tip, obscuring it. Upon withdrawal of the intravenous therapy venipuncture device, the sharp cutting tip of its needle stylet is fully protected by the invention's blunt metal stylet. The intravenous therapy device's needle stylet along with the inventions blunt tubular stylet firmly secured within now can be safely disposed of.
