摘要： 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.

摘要： A film-forming siloxane composition having excellent adherent and lubricating properties comprising a reactive component having a combination of three siloxane polymers chemically crosslinked, and a non-reactive component dispersed therein. Substrates are dipped or otherwise coated with the compositions, at which time they are cured quickly under heat to a durable, adherent lubricating surface which is dry to the touch. Of particular advantage is the use of these films on hypodermic needles, razor blades, catheters and the like.
