ABSTRACT
The use of insulin pumps is becoming increasingly common. Currently
the most frequently used pumps are battery-powered devices that are
filled with insulin and infuse it at a rate set by the wearer into the sub-
cutaneous tissues (usually the stomach) via a length of plastic tubing
and a needle. This is called continuous subcutaneous insulin infu-
sion (CSII). Boluses can be given as required at meal times.
