An evacuation dam apparatus including a frame having a top frame member, a bottom frame member, and two side frame members. A working area formed by the frame, a plurality of ports adjacent the working area, an outlet fluidly coupled with the plurality of ports. A fluid flow from at least a portion of the plurality of ports to the outlet forms a fluid flow path across the working area and at least a portion of the fluid flow path is formed within the frame.

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.

An affordable, reusable or one-time usage cup which enables effective and efficient collecting and removing of ejected aerosols/droplets from the mouths and/or nasal passages of dental patients but with enough room to still perform any dental procedure. The cup is connected to a vacuum source. The design of the cup is generally funnel-like and includes a cover which catches large debris ejected from the dental patient. The cup may include a variable height rim surrounding the input opening and significantly removes any aerosols/debris ejected from the patient thereby lowering the exposure of the dental professional to airborne and surface contaminants. The cup cover, occluding the main cup opening, includes holes through which any aerosols/droplets pass.

The present disclosure generally relates to oral care systems and devices. An oral care system includes a container defining an interior portion and a moveable funnel configured to slide in the interior portion of the container. The moveable funnel includes a funnel portion having a base connected to a tube. The system further includes a toothbrush supported by the tube, the toothbrush having a handle extending out from the container.

A suction handpiece for a dental treatment unit has a negative pressure connection which can be connected with a negative pressure source of the treatment unit. A saliva connection of the suction unit can be connected with a saliva suction cannula and an atomized spray connection that can be connected with an atomized spray suction cannula. A branched flow path connects the negative pressure connection with both the saliva connection and the atomized spray connection and includes a branching section on which a negative pressure channel ending on the negative pressure connection divides into a saliva channel ending on the saliva connection and an atomized spray channel ending on the atomized spray connection. The atomized spray channel at its narrowest point has a first cross sectional area which is at least twice as large as a second cross sectional area at the narrowest point of the saliva channel.

The present disclosure provides a treatment assistance apparatus, comprising: a base; a first joint of which one side is coupled to the base to relatively move; a first arm of which one end is rotatably coupled to the other side of the first joint; a second joint of which one side is rotatably coupled to the other end of the first arm; an adapter arm of which one end is coupled to a first adapter to relatively move, and the first adapter is rotatably coupled to the other side of the second joint; a first driving part disposed in the first joint and configured to rotate the first arm; a second driving part disposed in the second joint and configured to rotate the adapter arm; a pressure part configured to stop a relative motion of the first adapter; and a controller configured to control the first driving part, the second driving part and the pressure part.

In order to improve the occupational safety of the treating personnel during a dental treatment of a patient, an apparatus is provided wherein the discharge of aerosols from the oral cavity during the dental treatment can be reduced to a particular extent or possibly completely prevented. To this end, a cheek retractor, in particular for holding the patient's mouth open during a dental treatment in the oral cavity or throat, is equipped with integrated suction, wherein a plurality of suction openings connected to a suction system are arranged on the lip support shell of the cheek retractor.
