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.
A safety device used to prevent accidental needle sticks upon withdrawal of sharp intravenous puncture devices comprising: (a) a hollow tubular stylet with two blunt ends of which first end protrudes beyond a tip of said sharp intravenous puncture device, such as a needle stylet, to obscure said tip when inserted into said intravenous puncture device, (b) a clear plastic cylindrical hub to which said hollow tubular stylet is permanently bonded on second end and is designed to allow easy and secure fitting to all conventional sized medical syringes tips and male connectors of existing commonly used intravenous therapy tubing by either friction fit of Luer lock connection and (c) barbed friction catches which are molded on said hub to form a permanent component of said hub and secures the safety device within the intravenous puncture device.
