Our technology

Our technology: the high frequencies

Our components


Why controlled high frequencies?

Our bodies are made up of trillions of cells. These, very schematically, are systems that differentiate themselves, and their inner environment, from the outer environment thanks to the cell membrane.

On both sides of the cell membrane there is a difference in potential, due to the different concentration of ions between the intracellular and the extracellular environment.

From here, we can outline the cell as a bioelectric unit with its own characteristics of conductivity and electrical resistance. Impedance is a variable that takes into consideration the whole bioelectric behavior of body tissues.

Experimentally, it has been measured that the impedance, or, simplifiying, the resistance of the tissues, decreases when the frequency of the electromagnetic waves that pass through them increases. Translated into practice: the increase in frequency, and in particular the range of high frequencies (3-30 Mhz), reduces the impedance of cells almost to zero.

Impedance variation to varying frequencies. “Electrotherapeutic devices: principles, design, and applications” - Clock, 2007

It can therefore be said that radio frequencies emitted by our devices go through the barrier represented by the most superficial tissues to penetrate deep and then exert their effect directly in depth, in the site of damage.

Clinical-therapeutical effects?

The interaction between biological tissues and high frequencies is at the basis of the beneficial effects (antalgic, antiedemigen, antiinflammatory, proregenerative) that develop during therapy.

The radio frequencies generated by our devices activate directly, and indirectly, numerous cellular metabolic cascades for the regeneration and repair of injuries.

The effects of high-frequency diathermy can be divided into:

  • Direct: release of nitric oxide (NO) from different cell species.
  • Indirect: significant rise in local temperature in target tissue.


Nitric oxide is an important biochemical mediator that has multiple effects: it is a vasodilator, active processes of neoangiogenesis, has an anti-inflammatory effect.

The effects of nitric oxide are amplified by the indirect-diathermic effects of high frequencies which increase local metabolism and affect the re-equilibrium of immune activity in the treatment site.

Handpieces and discoids

Focusmed® has invested heavily in the research and selection of the best materials to radiate energy from our electromedical devices to the patient in total safety.

Handpieces are a fundamental component of our electromedical products: custom-designed, certified, biocompatible and ergonomic.

At the apex of the handpiece there is an isolated discoid, coated in titanium dioxide. The discoid has been carefully designed to allow the delivery of treatment in total safety for patient and operator. The discoid surface, coated with vitrified titanium dioxide, is isolated from the external environment. In addition, the disc is easily removable from the handpiece so you can clean it quickly after each treatment.

The handpiece can slide on the skin without the use of gel or conductive creams, making the treatment much more practical.


Handpieces with titanum dioxide coating

The handpieces can be used in two different ways:

  • Static, that is, by placing the handpiece on the skin and holding it in position.
  • Dynamic, that is by sliding the handpiece on the area to be treated, so as to act on all the sore points in a single session

Insulated mat


The return mat is specially designed to be practical to use by the operator and comfortable for the patient: it is soft, foldable and easy to clean.

It does not need to be placed in direct contact with the skin of the patient, so as to facilitate the use of devices on any district and in any context: from the bed of the unit or at the patient’s home.

This innovative accessory has been specifically designed to promote and ensure comfort and therapeutic continuity in any situation.

Power in safety: the microprocessors

Within all our devices there are numerous mechanisms to control power delivery and high frequencies to ensure maximum effectiveness and efficiency in all clinical conditions.

Real-time control is guaranteed by several microprocessors that continuously control the correct balance between the numerous treatment variables, such as the power output, impedance and absorption of high frequencies by the tissues.


Case: resistant and practical

The steel case of our portable electromedical is made of materials that are extremely resistant to shocks and temperature changes.

The certification for home use of the Pronexibus Plus® and the Rinovacell® testifies to the great versatility and resistance of our products.

The case is reinforced in steel, lightweight, compact, shock-resistant, and resealable with the appropriate security keys.

Pronexibus Plus® has been designed to be practical, portable, and is also certified for home use.

Mobile support: safe and handy

The mobile support is designed to use the electromedical devices in total safety and freedom.

The mobile support:

  • It has a special compartment for the case and supports for the handpieces.
  • It is built with solid materials and easily sanitizable.
  • Sliding wheels don’t leave marks on the floor.


Focusmed® always make sure to choose the highest quality using materials of first choice strictly Made in Italy.


Advantages of FocusMed® technology

To effectively summarize the advantages of Focusmed electromedical technology, we can divide them into two categories: biological advantages and technical advantages.

The biological advantages are numerous, including:

  • The therapy can be carried out directly on the target tissue of greatest interest, whether it is deep (e.g. muscles) or superficial (e.g. regeneration of skin wounds).
  • Absence of complications: the endogenous heat that develops during treatment is physiologically balanced by the blood hyperinflux that develops in the body district of interest.
  • Remarkable anti-edema effects since the very first sessions (e.g. significant reabsorption of edema also found with the naked eye).
  • Remarkable anti-inflammatory and antalgic effects since the very first sessions: the patients themselves report a clear improvement of their symptomatology.
  • Significant proregenerative effects, both in the context of skin lesions (e.g. regeneration of ulcers) and muscle lesions (e.g. previous muscular tears with reconstructive scarring outcomes).


The technical advantages are also numerous and significant, especially for the quality of the operator’s work:

  • It is extremely easy and easy to use: simply place the disc on the skin of the patient to treat it.
  • The devices are designed in the convenient format of a portable case: they are designed and certified for their use at the home of patients.
  • No mechanical operator-dependent contribution is needed: thanks to the high frequencies, the treatment is delivered as soon as the discoid touches the skin of the body area to be treated. The operator can then carry out the session without exerting any strength: this allows him to get less tired and get to the end of the day having done even more treatments and rested.
  • The mat does not need direct contact with the skin of the patient: this makes its use very practical, that is, the patient can lean on the mat with clothes still on.
  • Focusmed devices need neither creams nor conductive gel for their use, on the contrary, it is recommended to avoid them.
  • High-frequency diathermy does not need any prophylactic cryotherapy: the risk of damaging and scalding the skin is absent.
  • The discs are extremely easy to remove in order to disinfect them properly before each session.
