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 hub has a special light source connection to enhance the degree of light available for visualizing vein entry. The distal end of the fiber optic is polished to be the distal point of the needle. This polished distal end reflects color, such as red blood, immediately upon vein entry and exposure to blood, with the enhanced reflected light, 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.
