How is an insulin pump inserted?

Most aren't: A few clinics are involved in research for implanted pumps, where a surgeon places a pump under the skin in the abdomen, and a doctor uses a syringe to load Insulin into the pump once a month. Most Insulin pumps, though, are external pumps, where only a thin plastic tube, or catheter, goes under the skin to deliver Insulin into the fatty tissue, just as a syringe does.

Insulin pump infusio: Most Insulin pumps have a fine plastic tubing which connects to a catheter that is inserted on skin usually in the abdomen or thigh using an inserter. The Omnipod does not have an infusion catheter. rarely the catheters site does get infected. Changing the catheter every 48 to 72 hours is recommended. The catheter site should be cleaned before insertion to reduce risk of infection.
