For many sets, an “insertion device” is available. An insertion device is a push-button, spring-loaded tool that inserts the set. Many people feel it is easier and less intimidating to use than inserting it free hand. Specific insertion devices are available for specific infusion sets.
There are many types of infusion sets, but they can be categorized into two main groups – an “angled” set or “straight” set.
Angled sets are generally inserted at a 30-degree angle. They sit laterally under the skin. The cannula and needle are available in different lengths.
Straight sets are inserted perpendicularly at a 90-degree angle. The cannula is available in different lengths. Many sets come with an insertion device.
Infusion sets are an important part of successful pump therapy because they must provide constant insulin delivery. A crimped cannula, for example, can interrupt delivery and result in dangerously high blood sugars and ketone formation. (See Ketones and insulin pump therapy.)
