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:
“The best thing about Sassy Seats is that grandmothers cannot figure out how they work and are in constant fear of the child’s falling. This often makes them forget to comment on other aspects of the child’s development, like why he is not yet talking or is still wearing diapers. Some grandmothers will spend an entire meal peering beneath the table and saying, “Is that thing steady?” rather than, “Have you had a doctor look at that left hand?””
—Anna Quindlen (20th century)
