1. Activa Brand Products Inc.

Prince Edward Island, Canada

This company makes the AdvantaJet range.

Instead of using exchangeable nozzles it produces a separate pen to suit your specific requirement.

Common to them all is:-

A choice of 6 pressure settings.
Dosage range of 0-50units of insulin
An audible click dial.
Stainless steel and plastic construction.


The GentleJet

This Injector is for those of you with sensitive skin and particularly for children as it uses a lower pressure.

The AdvantaJet

This is the standard model for most of us out there.

AdvantaJet ES

This is for those of you with thick or tough skin. It works on a higher pressure.


Sorry, I only have prices for the USA and Canada, which I hope are up to date.
All three pens cost $495.00 in the USA and $695.00 in Canada.
A box of 4 replacement Vial Adapter will cost you $20.00 in the USA and $28.00 in Canada.

Though the cost may seem high one must remember that the pens will last for a considerable period of time. Activa claims that can be up to 10 years.

Activa even has a special system, called the Lifetime Benefit Program which enables you to replace your pen as many times as you want (after the 2 year warranty has expired) at a reduced price that is fixed for your lifetime.

The price is reviewed yearly but you pay the one that was in force in the year you bought your pen eg. if you bought your pen in 2001 and the replacement price was fixed at $225 that is the price you will pay for a replacement from 2003 to eternity.

This same price also applies if you want to change your pen to one of greater of lesser strength - not a bad deal it seems to me.

Activa have a good website explaining all about their product.

2. Antares Pharma Inc

Minneapolis USA

This company makes the Medi-Jector VISION.

It offers a choice of three different nozzles, A,B and C.

A has the smallest hole size and C the largest. Depending on your skin thickness and body mass you will need to use one or another of these nozzles. One finds out by trying the average one, B, and working up or down from there. Getting the right one for you can help eliminate pain and bruising.

The nozzles are transparent so you can check the insulin after loading and see that it has all been delivered. As stated this does away with the complaints in the older syringes of incorrect dosing.

The nozzles are stated to work for 21 injections, after which they need to be replaced.

It also claims to be maintenance free & to deliver around 3,000 injections.

Cost -

This varies between the suppliers as you will see from my info below. You will need to shop around. There are various web based shops where you can buy these.

For example


Medi-Jector Vision Injector Start-up Kit

- from $299.00 up to $335.00.

This kit includes:-

Medi-Jector Vision Injector
Injection Supply Start-up Kit - 2 nozzles and 2 vial adapters
Carrying Case

Training Video

Medi-Jector Vision Needle-Free Syringe Kit

- from $28.99 to $29.95.

This includes:-

4 nozzles and 2 vial adapters with caps. They state this is enough for 84 injections.

Some vial adapters have plastic needles and others have metal. The metal ones are slightly more expensive, around $31.95 for the above kit.

In India, Shreya Life Sciences, which is based in Mumbai, now markets the Antares Pharma's Medi-Jector VISION under the brand name Recojet.

This is sold along with a recombinant human insulin made by SciGen Ltd. in Singapore, called Recosulin - so we get the Recojet for the Recosulin - that should be easy to remember.

3. Bioject Medical Technologies.

Portland, Oregon USA

This company makes the Vitajet 3.

(This does away with the complaints in the older syringes of incorrect dosing).

The sterile nozzle and vial holder work on a "snap-on and click" design for ease of use.

4. Equidyne Systems.

San Diego, Calif

This company makes the Injex 30.

This differs slightly from the other makes of jet injectors in that it uses a sterile disposable ampoule, looking a bit like a needle-less syringe, that you fill from your insulin vial, via a vial adapter, before each injection.

The ampoule is then attached to the injector, the injector is placed against the skin, the trigger is pushed and the insulin in the ampoule is forced out of the tiny orifice through the skin into the subcutaneous tissue. The ampoule is then discarded.

The ampoule, though it resembles a normal syringe, sans needle of course, is much stronger than a normal syringe because it has to withstand the pressure needed for the insulin delivery. The dosage range is 5 to 30 units (.05 to .30 ml.) and the ampoule is marked in both units and millilitres.

It takes any type of U100 insulin and you can mix insulins.

The Injex 30 contains a special duel safety system to prevent accidental discharge - when the device has no ampoule in it the first level safety is automatically on. This stops you from accidentally releasing the tensioned spring - we are all inclined to fiddle with our toys are we not?

Once you place an ampoule into the injector this first level safety is deactivated but you can manually set a second level of safety by turning a safety ring on the injector to the "safe" position.

While this is activated you are unable to trigger the device and discharge the insulin. When you are ready to give yourself the injection you turn the safety ring to the "safe off" position and the device is primed for use.

Along with the injector and ampoules comes something that looks like nothing so much as a common office stapler. In actual fact it is a novel and handy little addition that winds the spring in the Injex 30 for you. You just place the injector in the Reset Box after each injection and once you close the box the device is set ready for the next injection - it does away with manual spring winding.

The Vial Adapter, which fits over the common insulin vials, is meant to be disposed of along with the empty vial. It has a tethered cap that fits over the top of the vial adapter when insulin is not being drawn up.

At the moment this device appears to be for sale in the US and in parts of Europe, especially in Germany. To find out more about which places in Europe go to and click on 'international sources'.

The cost:-

This device is around $260 for the Starter kit, which contains:-

The Injector
The Reset Box
8 disposable ampoules
2 disposable vial adapters
8 alcohol wipes
2ml vial of sodium chloride (for practice)
Injex Instruction Manual, training video, carrying case, and warranty card with envelope.

The disposable ampoules cost around $55 for 100.
Disposable Vial Adapters cost around $11 for 10.

5. The Medical House PlC.

Sheffield. UK

This company makes the mhi-500.

It is the only jet injector you can get on prescription in the UK and that means, for you folk out there who do not understand how the National Health Service (NHS) in Britain works, that as a diabetic one can thus get it free.

It appears to also be sold throughout the European Union and in Israel, Egypt, Iran, Malaysia and Singapore.

Wondering if it is available in your country? Go to their website, and look under Products - availability, (bottom of page, scroll down) this gives you a list of exactly where it is available.

It is the result of a joint project with Biojet, Inc, USA and is modelled on the Vitajet3. It is basically a second generation Vitajet3.

The improvements claimed for this device are :-

1. It is smaller, lighter and better looking.
2. It has audible 'click' dosing - better for those with poor sight.
3. Improved sterility by the use of a sealed cap.
4. The dose viewing window is magnified so it is easier to read.
5. Carrying convenience - it has a hard carrying case which offers better protection.

Like the Vitajet3 it claims no maintenance except the weekly nozzle change, designed to last for 3,000 injections, ability to be used either left or right handed, a transparent nozzle so you can check the insulin after loading and see that it has all been delivered. This does away with the complaints in the older syringes of incorrect dosing.


(if not part of the NHS) is £120 and the replacement disposable parts will cost around £72 a year.
