How Does An Insulin Pump Work?

An insulin pump is a device about the size of a deck of cards that can be worn on a belt, kept in a pocket, or worn on your skin. It carries a reservoir of insulin connected to narrow, flexible plastic tubing (cannula) that is inserted just under the skin. Users set the pump to give a basal amount of insulin continuously throughout the day. Pumps also release bolus insulin to cover meals and at times when blood glucose levels are high, based on programming done by users. Insulin pumps control your blood sugar levels by delivering fast-acting insulin 24 hours a day. Before you can use an insulin pump, you must undergo a surgical procedure. Your doctor will create a place for the insulin pump to connect to your body. The area to insert the needle is usually created on your abdomen. You will need to use a needle to connect the pump's thin, plastic tube to your body. Once you have inserted the needle, you should cover and protect the site with a bandage. You will need to change the needle every few days. There are three different types of insulin dosages that will be used with your pump. Basal rates are the first type and are the dosages that are automatically given to you 24 hours a d Continue reading >>

    I have worn some version of an insulin pump for about 20 years.
    The pump is programmed to give you a steady "stream" of insulin continuously (basal rate). When you eat something, you program in an additional amount of insulin to cover the carbohydrates you consume (bolus).
    Most pumps are about the size of a pager. You fill a reservoir in the pump with insulin, this reservoir connects via a slender tube to a flexible "needle" (called a canula) that is inserted directly under the skin (subcutaneous). This needle is the only one you ever use on youself and remains connected to you for anywhere from 1 to 4 days (depending on your skins "tolerance").
    The isea is that it "mimicks" a pancreas. The programming in the pump can be adjusted for activity levels, illness, etc.
    They are extremely expensive ($3,000.00-5,000.00). Most are very rugged, built to withstand pretty rigorous activity.
    The only thing I'd like more than mine is a cure.
