Definitions

  • the present application relates to dental systems and, more particularly, to a containment device for containing aerosols or particulate debris produced during a dental procedure on a subject.
  • Illnesses are commonly shared in the workplace, but the risk of exposure may be significantly higher for dental professionals using powered instrumentation such as ultrasonics, air polishers, and drills.
  • Bacteria and viruses can spread rapidly through splatter, aerosols, and particulate debris produced by these types of treatments. That is, aerosols, particulate debris, and splatter produced, for example, by ultrasonic, drilling, and air polishing treatments can contain saliva, blood, bacteria, and pathogens. Once airborne and uncontained, aerosol particles can linger in the environment for an hour or more while particulate debris and splatter can end up on the surfaces immediately surrounding the treatment area.
  • SARS severe acute respiratory syndrome
  • TB tuberculosis

  • the suction nozzle 500 can be disposed about the pivot point 260 such that the laminar air flow 400 / air barrier extends only along the headrest 210 / backrest 220 portions of the dental chair 200 in the reclined position.
  • the air emitter nozzle 300 is arranged such that the air barrier formed by the laminar air flow 400 defines a width extending across the headrest 210 of the dental chair 200. For example, as shown in FIGS.

Abstract

L'invention concerne un système de confinement d'aérosol dentaire comprenant un fauteuil dentaire conçu pour être mobile entre une position assise verticale et une position inclinée, et une buse d'émission d'air disposée adjacente au fauteuil dentaire et conçue pour émettre un flux d'air laminaire à travers le fauteuil dentaire dans la position inclinée. Le flux d'air laminaire fournit une barrière d'air sur le fauteuil dentaire dans la position inclinée pour faciliter le confinement d'un aérosol ou d'une matière particulaire entre ces derniers.
