Abstract
A needle point protective device for hypodermic and intravenous needles, catheter introducers, and similar devices protects users from injury and infection. The needle point protective device includes a needle point guard that is slidably mounted within the needle handle. In use, the needle point guard is integral with a cannula guide that is engaged with the needle cannula with enough force to cause the needle cannula to be subject to spring tension when the needle point is retracted proximal to the needle point guard, the needle point springs downward and behind the needle point guard. In one embodiment, the needle point guard is held in position manually as the needle is retracted. In another embodiment, the needle point guard is held in place automatically as the needle is retracted.
