A oral suction device that incorporates a foldable suction body, a bite block and a suction adapter that is utilized to block the throat cavity. The body draws water, saliva and debris from about a gap along its outer perimeter. The suction body resides in a vertical position in the patient's mouth and is able to expand to allow the transport of large pieces of debris without coming apart. There is a fishtail section of the suction body that anchors it between the teeth and the inner cheek so as to allow the remained of the suction body to block the throat hole.

An intraoral device for dental isolation and fluid evacuation is disclosed. The device includes a first flap and a second flap positioned adjacent to the first flap to form an evacuation chamber, the second flap including a plurality of peaks and troughs forming a waveform shape at a first edge and a second edge of the second flap, the plurality of peaks and troughs forming a plurality of channels in fluid communication with the evacuation chamber; and an evacuation source connection portion including an opening that is in fluid communication with the evacuation chamber and configured to facilitate fluid evacuation when the evacuation source connection portion is attached to an external vacuum suction device, wherein an interior second flap surface is configured to touch an interior first flap surface at the plurality of troughs at least when suction is applied by the external vacuum suction device.

An intra-oral dental appliance is provided. The intra-oral appliance can have an external member, flexible and poseable first and second suction arms having tubing and a connector connected to the first and second suction arms, the connector connectable to a vacuum source. The first and second suction arms positionabe independently from one 5 another and connectable to the external member. The external member can have first and second apertures sized to accept tubing to hold the tubing in place.

A disposable dental aerosol device has a tube having a tip end having a tip having a tip opening, a valve receiving end having a rear end opening, and an aerosol directing device having an aerosol collecting funnel, a first vane, a second vane, a first aerosol capturing port formed between the first vane and the second vane, and a second aerosol capturing port formed between the second vane and the first vane.

An oral cavity cleaner includes a mouthpiece that sprays washing water into the oral cavity, a core suction part that suctions contaminated water formed by mixing the washing water and saliva inside the oral cavity, and a handle having an inflow path for introducing the washing water, a discharge flow path for removing the contaminated water, and a diffusion flow path that defines a space through which the washing water is directed toward at least one of the upper or lower sides of the discharge flow path and is delivered to the mouthpiece.

The disclosure relates to a saliva suction device for an intraoral radio-frequency coil, comprising a body and a suction opening configured to be connected to a vacuum system, wherein the body is configured to provide a mechanical connection between the saliva suction device and the intraoral radio-frequency coil, wherein the intraoral radio-frequency coil is configured to receive magnetic resonance signals from a dental region of a patient, and wherein the suction opening is configured to remove saliva from an oral cavity of the patient during a magnetic resonance measurement. The disclosure also relates to a combined intraoral suction device comprising a saliva suction device and a magnetic resonance device comprising a saliva suction device.

A dental aerosol protection system for controlling dispersion of aerosol and splatter particles produced during dental procedures, the system including a ring assembly, a support mask for supporting the ring assembly on a patient, and a suction generating device, the ring assembly and support mask having suction ports which are connectable to the suction generating device to provide a negative suction force around the oral cavity, wherein the ring assembly and support mask can be connected or used separately to control dispersion of aerosols depending upon the requirements of the dental procedure, and one or more flexible extensions connectable to the ring assembly and support mask extending superiorly away from the patient around and over the oral cavity, the flexible extensions forming an adjustable physical barrier between the dental professional and the patient's oral cavity.

An oral suction device includes a vacuum hose connected to a suction source, a vacuum tip having a tube body that has a proximal end connectable to a distal end of the vacuum hose and a distal end as a suction port, and a bag-shaped light source holder provided on a tube-body outer surface, on a tube-body inner surface, or in a tube wall of the vacuum tip or at locations corresponding to a combination thereof, extending along a longitudinal direction of the vacuum tip, and having an opening at one end.

Disclosed are a workbench control assembly, a workbench waterway integrated system and a dental nurse workbench. The workbench control assembly includes a cleaning assembly, a spittoon, a saliva suction assembly, a sewage container, a first conveying assembly and a second conveying assembly. The spittoon is connected to the cleaning assembly and configured to receive mouth rinse wastewater, the saliva suction assembly is configured to contact oral sewage or connect to the cleaning assembly, the sewage container is connected to the spittoon and the saliva suction assembly, the first conveying assembly is connected to the cleaning assembly and configured to convey a cleaning liquid supplied by the cleaning assembly to the spittoon and the saliva suction assembly respectively, and the second conveying assembly is connected to the sewage container and configured to convey a mixed liquid conveyed to the spittoon and the saliva suction assembly to the sewage container.
