An insulin port functions as a medication delivery channel directly into the subcutaneous tissue (the tissue layer located just beneath the skin). When applying the injection port, an insertion needle guides a soft cannula (a small, flexible tube) under the skin. Once applied, the insertion needle is removed and only the soft cannula remains below the skin, acting as the gateway into the subcutaneous tissue.
To inject through an insulin port the needle of a syringe or insulin pen is used. It is usually used to deliver insulin through the use of an insulin pump. The needle remains above the surface of the skin, while the medication is immediately delivered through the soft cannula and into the subcutaneous tissue.
Famous quotes containing the word port:
“The very best place to be in all the world is St. Mary’s parish, Jamaica. And the best spot in St. Mary’s is Port Maria, though all of St. Mary’s is fine. Old Maker put himself to a lot of trouble to make that part of the island of Jamaica, for everything there is perfect.”
—Zora Neale Hurston (1891–1960)
