NeedlesHypodermic needles are actually small cutting tools. Puncturing the skin and vein with needles results in small cuts or slits, which will eventually lead to deterioration. The larger the needles, the larger the cuts made in the skin, and the shorter the life of the simulator. It is recommended that 22-gauge or smaller needles be used. Always use sharp needles. Dull or bent needles cause excessive tearing.
