Pen needles for optimal patient comfort Unifine® Pentips® offer patients a comfortable injection experience thanks to their design. Many people with type 1 or type 2 diabetes hesitate to inject insulin due to pain. With Unifine® Pentips®, only minimal injection force is required, which increases comfort and minimizes negative experiences. Improved usability through thoughtful design Four design aspects ensure easier injection: The precisely sharpened tips reduce the required piercing force. The thin-walled construction improves the flow of the medication, requires less finger strength, and reduces the risk of thumb osteoarthritis. The Anti-Coring Technology enables clean piercing of the ampoules without fragments. A special silicone lubricating film minimizes friction between the needle and the skin, making insertion and removal of the needle easier.
