InsuJet needle free insulin delivery

*We can only offer demonstrations to healthcare professionals within the UK.


InsuJet ™ is a device that can be used to administer insulin without a needle – so great for needle phobics. The insulin is fired at high pressure through a small hole, which creates a high speed jet that can penetrate the skin and underlying tissue. The pressure is generated by a powerful spring which is optimised for subcutaneous insulin delivery.

The injection technique used is just as important for glucose control of individuals as is the type and does of insulin delivered.1-5 Precise insulin dosage is an essential part of daily self-management of diabetes and there is always a risk of inappropriate administration technique.

  • 40% of users dispose of used needles inappropriately.6
  • 32% of individuals re-use needles more that 6 times potentially causing damage to both the needles and their skin.6
  • Inappropriate needle-length selection and poor skin-fold technique can increase the possibility of intramuscular injections.3


InsuJet disperses insulin in the subcutaneous tissue. With needle injections, insulin is simply pushed through the skin and is more concentrated in a droplet. With Insujet, the insulin is spreads through the subcutaneous tissue in a cone-like formation maximising insulin absorption  into the circulation.


Rapid-acting insulin analogues can still take up to 30 minutes before they start working. Insulin administered by InsuJet shows activity after just 15 minutes – faster than traditional insulin injections. As this effect mimics the endogenous insulin profile (faster uptake, higher Cmax and faster drop off)7, using InsuJet may help reduce HbA1C levels. A long term study is planned to compare HbA1C in users using needles with patients using Insujet.

In a glucose clamp study, rapid-acting insulin analogues administered by InsuJet resulted in a faster onset of action and higher insulin peak values than insulin injected by conventional insulin pen. The peak  concentration of insulin administered by InsuJet was reached after just 27 minutes compared to the peak of the pen-injected insulin which was reached after 45 minutes (<0.0001).7

InsuJet results in a more rapid intake of insulin compared to administration by conventional injection methods. The pharmacological profile of insulin delivered by jet injection more closely resembles the profile of endogenous insulin secretion.7
