Abstract
A device is provided for indicating when an intravenous needle has entered the vein through the use of a solid fiber optic mounted in the needle for showing visual instantaneous vein entry. The distal end of the fiber optic is polished to be flush with the distal point of the needle. The fiber optic is sized to have an outer diameter which will extend through the cannula of the needle. This polished distal end reflects color, such as red blood, immediately upon vein entry and exposure to blood to the magnifying system forming a part of the invention at the rear or proximal end of the fiber optic. The user observes immediate vein entry without any blood flow or exposure to blood. Other embodiments utilize the fiber optic as the needle, thus eliminating the needle itself.
