While the elimination of needle sticks may sound appealing, these devices have had only limited use so far. Even after considering the following factors, be sure to ask your doctor if you can try out a jet injector first before making a purchase. Jet injectors deliver accurate doses that are more rapidly absorbed than subcutaneous injections. They may be of particular benefit for patients who have an extreme fear of needles. These devices are bulkier than syringes, however, and also require the user to carry vials of insulin.
Some people find jet injectors no less painful than needles.
They may still cause pain and bruising at the injection site, and can damage the skin if not used properly. Jet injectors are expensive. About the size of a pager, these computerized devices are usually worn discreetly on a belt or placed in a pocket. Patients adjust the size and timing of these bolus doses according to when and how much they wish to eat. The pump also makes it easier to adjust mealtime bolus doses.
