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:
“When children dress like adults they are more likely to behave as adults do, to imitate adult actions. It is hard to walk like an adult male wearing corduroy knickers that make an awful noise. But boys in long pants can walk like men, and little girls in tight jeans can walk like women.”
—David Elkind (20th century)
