Is Bleeding Possible?

Bleeding usually does not occur. As with needle injections, Inojex might cause some damage to the uppermost capillaries. In rare cases, this might cause a pin-sized drop of blood to emerge at the injection site. This is especially the case if the patient has been taking medication to treat cardiovascular disease (e.g., Marcumar, ASS100 = time-released aspirin) or normal aspirin for pain relief.

Are Inojex Unintended Intramuscular Injections Possible?

No. The pressure and speed are calculated in such a way that the medication only enters into the subcutaneous adipose tissue. Accidental administration of the medication into the muscle is virtually impossible.

In contrast to insulin injections in diabetic children that frequently and unintentionally are performed intramuscular when using a needle syringe (30,5 % of performed injections). (literature review: POLAK et al., 1996)

Which medications can be used with Inojex?

Medications licensed for subcutaneous use can be administered with the needle-free Inojex.

The main applications for the Inojex system at present are diabetes (subcutaneous administration of insulin), the prevention of thrombosis (by means of Heparin) and local anaesthesia (e.g. prior to venous catheterisation, prior to minor surgical procedures or for dental infiltration anaesthesia). Other applications for Inojex are the treatment of dupuytren’s disease or homeosiniatry. Please note the technical reports for these mentioned applications.

Is the injection with Inojex painless?

When applied correctly the injection with Inojex is virtually painless. The sensation can be described as a short slight pressure on the skin surface. As pain is felt individually one cannot state a general and obliging assertion. As fluid is pressed under the skin the patient will sense the injection with Inojex more or less, depending on the volume and the individual sensibility. Patients generally assess the sting from a needle as more unpleasant than the injection with Inojex .

The micro orifice of the needle free syringe has a diameter of 0.17 mm. Currently, the thinnest needle has a comparatively thick diameter of 0.25 mm.

Can the needle-free syringe be used again?

No. In order to guarantee sterility and function, the needle-free syringe are intended to be used once only.

What are the minimum respective maximum quantities of medication that can be administered per application?

A minimum of 0.03 ml, and a maximum of 0.30 ml of a liquid drug can be administered using the INOJEX. For insulin, it delivers between 3 to 30 Units using the U-100 insuline of choice.

Is it possible to treat Inojex system components in an autoclave?

No, the utilized materials are not suitable for autoclave treatment. Adapters, needle-free syringes and SiliTops are sterile products for single-use only. The injector, the reset box, and the transporter are designed for multiple-use and need not be sterilized since they are not in direct contact with the patient.


What are the advantages of Inojex?

The Inojex system has many advantages, including the following:

•Without needle
•Virtually painless
•Reduces psychological inhibitions and fears
•Minimizes injection-induced stress
•Targeted anaesthetizing of specific areas possible
•Easy dosing of anaesthetic
•Economic since only small doses of anaesthetic are required
•Less time between injection and effect due to shorter dispersion times of the anaesthetic compared with conventional syringe, thus saving time
•Anaesthetic effect below limit dose for local anaesthesia – also with children
•Fewer risks of side effects or negative interactions with other medications due to lower doses
•Elimination of injury to patient and physician caused by needle
•Safe and easy use
