INJEX system (needle-free injection)
|
 |
|
This system is an alternative to the use of conventional syringes on the part of dentists, as it permits the pain-free administration of anaesthesia in the front part of the mouth, removing the psychological barriers of patients.
Another advantage of this system is its safety, as it permits professionals to apply anaesthesia directly and exactly, without risk of infection through chance shots and without damaging the tissue as needles can do.
These features of the system open up, in addition, numerous therapeutic possibilities for other fields of medicine, such as the treatment of diabetes.
The Injex system is based on the following principle: without needing to use a needle, the liquid penetrates the subcutaneous tissue through a high pressure injection. A spring inside the injector produce the elastic force necessary to liberate the established volume of anaesthetic, through a micro-pore at the tip of the ampoule.
Injex presents a multitude of advantages, both for the professional and the patient: greater quality of patient care, easy manipulation, possibility of using any type of anaesthetic, avoiding chance puncture wounds and avoiding fear of the needle.
What’s more, Injex also has various advantages from the histological point of view: it avoids the risk of the anaesthetic penetrating the blood vessels, does not damage the tissue, requires the use of lower quantities of anaesthetic and it acts faster.
Despite the small quantity of anaesthetic used, the effect is sufficient for the work to be undertaken. On the other hand, the painless sensation of the technique is valuable in the majority of cases and, above all, as is the reduction in anxiety produced by the needle. This is especially effective when we treat children, as by not seeing a needle they remain calm and the result, at both patient and medical level, highly positive.
