The device has the main purpose to optimize the suction power of normal dental aspirators. In addition to optimizing its suction features, the shape guarantees a wider coverage in cubic meters of air affected by the suction process itself. The main objective of the device is to aspirate aerosols, air and liquid particles in the immediate peri-operative dental field. The device adaptable to common dental mouth openers for awake patients, and positioned outside the patient's oral cavity does not limit the movements of operators and dental assistants in normal daily practice. The aspirator has been designed to limit the diffusion and remote deposition of particles from the patient's oral cavity. In particular, the device sees its main field of use during the pandemic caused by the new Coronavirus 2019. Recent studies have shown that SARS-CoV-2 (Severe Acute Respiratory Syndrome - Coronavirus - 2), has remarkable persistence on different surfaces. The virus can remain infectious in aerosols for hours while on surfaces for up to days. COVID-19 is mainly transmitted by aerosols, which takes about 66 minutes to halve the number of viable virus particles. 25% still maintain virulence after just over an hour and 12.5% of the viral load persists after about 3 hours. Even on some metals, such as stainless steel, the viral load is halved after 5 hours and 38 minutes. On the plastics, however, the half-life is 6 hours 49 minutes; on the cardboard the half-life is approximately three and a half hours. The viral load on copper halves faster than elsewhere, where half of the virus is inactivated within 45 minutes. Drinking water sanitation systems should ensure that the virus is removed or inactivated. It is easy to understand how the dental operating environment is exposed to this type of risk. Many dental devices need irrigation or cooling, which in the form of nebulized water generates aerosols, which from inside the patient's oral cavity could easily spread at a distance and on neighboring surfaces (doors, furniture, chairs, lamps, windows). By intercepting the aerosol, the particles during dental practice, the device should significantly reduce this spread, allowing prevention in the case of positive patients and better safety at work.
