SIRIO is a low frequency ultrasound device engineered for the treatment of a vast range of diseases affecting the musculoskeletal system.
The core of the device is constituted by a sinusoidal generator that controls the piezoelectric transducers of the hand probes with signals that are adjustable in amplitude and PWM.
Sirio is equipped with a microprocessor that constantly monitors and adjusts the oscillatory movements generated by the transducers in relation to the response of the biological tissues treated. By doing so, the device generates an increased physiological activity of the circulatory and lymphatic systems.
This biological stimulation contributes to the activation and acceleration of the body’s natural reparatory processes in the areas treated with Sirio, thereby allowing for a faster, enhanced resolution of the indicated pathologies.
The R&D capacity of BAC Technology applied to the design and in-house manufacturing of Sirio is supported by numerous scientific studies in the fields of biotechnology and biomedical engineering that have been carried out in the course of decades, which testify the efficacy and clinical safety of the technology employed by Sirio.
The device is entirely manufactured in our facilities in Italy. Its production respects the highest CE and ISO quality standards of processes and materials, a factor that has allowed BAC Technology to certify Sirio as an approved medical device at the Italian Ministry of Health. (N° 44786, 20/09/2011).
Referring to the theoretical principles of physical acoustics, ultrasounds are subject to phenomena of reflection, refraction and diffraction. Through SIRIO, the pressure wave that propagates within the biological tissues treated progressively fades and disappears. This pressure wave propagation transfers energy, thereby determining a mechanical cell handling action, and, subsequently, a production of heat.
These two energy transformations represent the foundations of treatment with SIRIO.
The acoustic pressure wave (ultrasound) is produced by the hand probes, thanks to the activity and physical properties of its piezoelectric discs. These discs indissolubly bind the voltage applied to the two faces of each disc and the compression / expansion activity that the disc is subjected to, which is produced by the difference of potential that is applied to the two surfaces.
Through this mechanism, SIRIO generates electrical signals of appropriate amplitude and frequency. These signals are transmitted to the hand probes, that is, the opposite faces of the piezoelectric discs that generate the ultrasound waves.
Sirio's piezoelectric materials emit in a frequency range between 20 to 70 KHz. A. The gel interposed between the head of the hand probe and the biological tissues guarantees the necessary acoustic coupling and favors the mobility of the hand probe's head, optimizing the amount of energy transferred and avoiding energy dispersions from the hand probe to the tissues.
By exploiting the characteristics of low-frequency ultrasound, thanks to the exclusive construction and control technology of its transducers, Sirio has the following effects on the biological tissues:
• Mechanical vibration effect
• Thermal effect
• Cavitational effect
The effects generated synergically determine actions that develop at greater depths and with greater efficacy compared to those obtainable via 1 or 3 MHz ultrasounds.
Treatment with SIRIO is painless and free of side effects, even in the treatment of calcific tendinitis. These tissue alterations are usually treated with devices that generate a shock wave of either piezoelectric, electromagnetic or ballistic origin. Such treatments are comparable in terms of results to those obtainable with SIRIO, but such treatments are frequently more painful for the patient.
The feature that distinguishes the low frequency 38 KHz ultrasound from the most popular 1/3 MHz ultrasound is the ability of the former to produce, if appropriately interfaced with specific hand probes, an effect that is both thermal and cavitational. The software that operates in SIRIO’s hand probe interacts with its hardware, continuously changing the type of sound emission produced by the device.
By adapting its emission to different treatment parameters, Sirio is able to modulate a range of signals so wide that it can generate the effects produced by both traditional ultrasound devices and piezoelectric shock waves generators. This feature, unique in its kind, makes SIRIO an effective and versatile electromedical device for the treatment of a large number of diseases of the musculoskeletal system.
