Syringes

For people with diabetes, injecting insulin is essential for maintaining their health. Using a needle and syringe is a common and cost-effective way for many people to take their insulin.
 
An insulin syringe has three parts: a needle, a barrel, and a plunger. The needle is short and thin and covered with a fine layer of silicone to allow it to pass through the skin easily and reduce pain. A cap covers and protects the needle before it is used.
