Overview

Jet injectors deliver insulin beneath the skin using a high pressure jet through a tiny opening at the head of the injector. The opening is typically a fraction of the diameter of a needle. Proponents of jet injectors argue that the mist produced by the jet injector results in a better dispersal pattern of the insulin beneath the skin and is therefore less traumatic. Some also claim that jet injectors are less painful than needles.

Dispersal Patterns

Insulin deposited via needle

Needle Pattern

Insulin injected via a needle produces a pool of insulin beneath the skin, as shown in the first image. The insulin is absorbed by the body only on the periphery of the pool of insulin.

Jet Injector Pattern

Insulin injected via a jet injector produces a mist of insulin beneath the skin, as shown in the second image. Since the insulin is dispersed throughout the tissue, it is absorbed more quickly. Users of jet injectors often need to adjust their insulin dosage by a small amount to account for this effect.

Painfree?

Proponents of jet injectors often claim that they are less painful than needles. Some even say they are painfee. From postings in misc.health.diabetes by users of jet injectors, and discussions with a few users of jet injectors, the fact is that it depends upon the individual. People with little body fat or thin skin, such as kids, are likely to find jet injectors and needles equally painful (or painfree). People with some body fat, who inject in that area, will likely find that the jet injector is nearly painless. The GentleJet is one jet injector specifically designed with kids in mind.

Also, each user must determine the proper injection pressure by trying out various settings. Bruises result from too much pressure, while leakage results from too little. Getting it just right is part of the training provided by the jet injector manufacturer and will be a bit uncomfortable. Different parts of the body may require different pressure settings.
