Diabetes - Devices


Diabetes is a condition characterised by difficulty in controlling blood sugar levels. People with Type I diabetes and some people with Type II diabetes need regular injections of insulin. This topic discusses the devices available to deliver insulin injections.


Insulin cannot be taken by mouth because it is a protein and would be digested. Insulin must be given by injection which delivers the drug just under the skin where it is absorbed into the bloodstream. The following insulin delivery devices can be used by people with Diabetes.
Injection by syringe requires inserting the syringe under the skin and pressing the plunger to deliver the insulin.
Insulin Pens
Insulin pens look like a pen with a cartridge. They offer a discreet and convenient way of carrying insulin and needles. The tip of the pen is a fine needle and the insulin is held in a cartridge in the body of the pen. Insulin is delivered by turning a dial to select the desired dose and pressing a plunger at the end of the pen. Some pens are reusable while others are disposable.
External Insulin Pumps
Insulin pumps are mechanical devices that are programmed by the user to deliver insulin under the skin via a thin plastic tube and needle inserted into the abdomen (the needle is changed approximately every 2-3 days). The insulin pump and reservoir of insulin is contained in a small plastic case about the size of a beeper. Insulin pumps are designed to deliver insulin continuously over a 24-hour period in small amounts, keeping blood glucose levels within the desired range between meals and overnight. The user can Programme 'bolus' doses during meals to match the amount of food being consumed. Insulin pumps are a very intensive way of managing diabetes and require frequent blood glucose monitoring.


Always consult your Doctor for diagnosis and advice. In no way is this information intended to replace the advice of a medical practitioner.
Discuss the types of insulin delivery available to you with your Doctor or diabetes educator. It is important to be aware that not all methods of delivery are suitable for all people. Each method has its own advantages and disadvantages. Discuss any problems with taking your insulin with your health care professional. It is your body and your responsibility. Don't be afraid to ask queries of your Doctor, Diabetes Educator or Pharmacist.
