Applying, Wearing and Using
Injection ports are usually applied by the patient. The device comes with a needle surrounded by a soft cannula. The needle and cannula are manually inserted into the patient's tissue. Immediately after insertion the needle is removed and the cannula remains below the surface of the skin.
Ports are usually worn on the abdomen, but can also be worn on other areas such as the buttocks, thigh or arm. Typical injection ports are worn for 3-5 days and then replaced with another port.
Insulin is injected via a syringe into the injection port. Medication immediately flows through the device's cannula into the subcutaneous tissue layer. No medication is stored in the device (other than the small amount of dead-space in the medication channel within the device).

Famous quotes containing the word wearing:
“I felt more determined than ever to become a physician, and thus place a strong barrier between me and all ordinary marriage. I must have something to engross my thoughts, some object in life which will fill this vacuum and prevent this sad wearing away of the heart.”
—Elizabeth Blackwell (1821–1910)
