Buttons: Allows the wearer to make choices about how much insulin to deliver and when. Display screen: Interacts with the buttons to display information and choices available to the wearer. Circuit board: Converts the wearer’s instructions into action – increasing the pump’s motor to deliver a faster rate of insulin. Motor: Turns round causing the plunger to push insulin through the reservoir and into the tubing. Reservoir: Holds insulin (usually enough for a number of days’ insulin use) Tubing: Links the reservoir in the pump to the cannula which goes into the wearer’s body. Cannula: A small tube that goes into and just under the skin, allowing insulin to pass from the tubing, t Continue reading >>

    MiniMed just came out with a closed loop pump in 2016. Information is available on the net. You and your doctor may both check it out.
