Abstract
There are disclosed herein medical syringe and catheter devices which preferably can be disposable and non-reusable and which have features to minimize users from accidentally stabbing themselves before or after use. They comprise relatively slidable members for covering and uncovering a needle. A butterfly wing IV catheter is disclosed including a body having laterally extending tabs to help hold the catheter in place, along with a slide member configured to fit and slide within an opening in the body member and which member includes a needle and a hollow fitting for receiving flexible tubing. The slider member includes a boss adapted to fit within pockets of the body member to define respective extended and retracted positions of the needle.
