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:
“Through the port comes the moon-shine astray!
It tips the guard’s cutlass and silvers this nook;
But ‘twill die in the dawning of Billy’s last day.
A jewel-block they’ll make of me to-morrow,
Pendant pearl from the yard-arm-end
Like the ear-drop I gave to Bristol Molly—
O, ‘tis me, not the sentence they’ll suspend.”
—Herman Melville (1819–1891)
