The containment of aerosols produced in dental processes and treatments is of notorious relevance since they represent a high risk of transmission of infectious diseases, such as viral flu or COVID-19. Medical personnel in the dental area, or others, are exposed to a high risk of infection by constant exposure to these aerosols and splashes. Consequently, it is providing a protective shield for odontological procedures that functions as a physical barrier avoiding contact of dentists, orthodontists and/or their technicians/assistants with aerosols and splashes that occur during dental treatments and procedures.

A multifunctional air pollution reduction device includes a tool and a multifunctional pollutant remover. The multifunctional pollutant remover is adjacent to or integrated with the tool. The multifunctional pollutant remover can not only reduce air pollution, but also help reduce one or more of the following problems when using the tools: noise, vibration and/or slip.

A protective apparatus for use in medical and dental procedures to prevent exposure and exchange of harmful substances between an area isolated by the apparatus and the environment of use. The apparatus includes a physical shield, a vacuum barrier, and an adjustable support frame. The apparatus further includes a vacuum connector for connecting the apparatus to a vacuum source, a vacuum conduit for flow communicating with the air around the perimeter of the physical shield such that the vacuum source draws air along with solid and liquid matter entrained in the air into the vacuum conduit, and a plurality of vacuum apertures located along the vacuum conduit for communicating the vacuum source with the air. The apparatus provides protection for persons in proximity to a source of harmful substances such as aerosols derived from patients infected with viruses or the like and more in particular corona viruses.

A system for removing aerosol contaminants from the air in a room is disclosed. The system comprises a vacuum inlet coupled to a vacuum system and operable to draw air from nearby into the vacuum system, filter out aerosol contaminants present in the air, and return the filtered air back into the room. The system includes airways internal to a dental chair, through which air may be drawn and filtered. The system may be used near a patient during a dental or medical procedure to remove aerosol and splatter potentially containing such contaminants as COVID-19 and other infectious diseases.

A medical, in particular dental-medical, fan for extracting or compressing a gaseous working fluid, in particular air, comprises a compressor unit with an outer housing, which comprises an inlet opening for the working fluid and an outlet opening for the working fluid, which are fluidically connected to one another, and which defines a compressor sector and a drive sector.

Described herein are compositions in nanofiber form including one or more bioactive compounds releasably incorporated thereon. In one embodiment a composition is described comprising at least one nanofiber and at least one bioactive compound. The nanofibers are formed from a base material that is solubilized with the bioactive or bioactives in an aqueous based solvent solution and the base material and bioactives are together spun via electrospinning to form dry fibers with the bioactives chemically bonded to the nanofibers and the bioactives remaining stable during storage of the composition under ambient conditions substantially free of moisture. On exposure to moisture, the nanofibers dissolve, thereby releasing the bioactives.

An extra-oral capture hood includes a first cone that provides a first path for a vacuum product through the extra-oral capture hood. A second cone concentric with the first cone and disposed around the first cone provides a second path for the vacuum product through the extra-oral capture hood, the second path being located between the first cone and second cone. A disconnect is connected to at least one of the first cone or second cone, the disconnect being configured to connect the extra-oral capture hood to a duct, a valve or other component of a capture system.

A particulate collecting device for dental patients is disclosed. The device includes a pair of vertical flanges, with a first flange configured to be positioned and worn on a right side of a patient's chest and a second flange configured to be positioned and worn on a left side of the patient's chest. The vertical flanges have an inner contour that aerodynamically funnels air flow away from the patient's face. The device includes a protective sheet located between the vertical flanges. The device includes a particulate matter reservoir that is fluidly coupled to the vertical flanges and configured to receive funneled air, and particulates contained therein, from the vertical flanges. The device also includes a negative air pressure generator, which is fluidly coupled to the particulate matter reservoir and produces negative air pressure in a direction from a top area of the vertical flanges towards the particulate matter reservoir.

Medical gas or airborne contaminants can be evacuated from a vicinity of a face of a patient using an intake duct defining an intake opening at a single intake location. The single intake opening is supported offset to one side of a face of the patient and an exhaust flow is applied at a flow rate of greater than 200 cubic feet per minute such that a single flow is drawn across the face of the user and into the intake duct. By drawing from only one side of the face of the patient with the prescribed flow rate, the velocity of gases and airborne contaminants flowing towards the intake duct can exceed the forward momentum of gases and/or contaminants expelled by the patient so as to capture substantially all medical gases and/or contaminants in the vicinity of the face of the patient.
