A self-supporting tube can support an associated medical or dental device, such as an extra-oral aerosol suction device. The self-supporting tube can be configured as a high-volume evacuator tube for a dental chair system. The self-supporting tube can include a first end that connects to an HVE port of a vacuum collection cannister directly or through a U-shaped tubular fitting and/or the first end of the self-supporting tube can connect to an inlet of a high-volume evacuator valve, and the self-supporting tube can include an opposite second end that connects to the associated aerosol suction device. The self-supporting tube can include at least one lumen that fluidically connects the first and second ends. The self-supporting tube can further include a manually operated inline valve. The self-supporting tube can be disposable and can be formed into a desired shape. When connected to an HVE valve, the self-supporting tube can include an anti-rotational device. The self-supporting tube can be provided as part of a modular system including at least one flexible tube segment and the self-supporting tube connected together. The self-supporting tube can be connected to an associated support structure of a dental delivery system unit such as an assistant's chair by a sleeve. The self-supporting tube can be connected to a support arm extending from a stopper connected to an HVE valve cradle. The self-supporting tube can include an aerosol suction funnel formed as a one-piece structure with the remainder of the self-supporting tube.

An air handling and filtration/treatment system (whether portable of affixed) for the mitigation and management of airborne biological contaminants (either those pre-existing or those that may become generated) that includes a suspended air in-take assembly containing a removable filter; that includes a deflector having ducting leading to a housing assembly that includes a UV sanitizer, a fan assembly and controller; and includes an outflow assembly that includes ducting leading to a position able manifold having a plurality orifices. The manifold and deflector are laterally offset from the housing assembly and vertically aligned with each other. The manifold is positioned to encircle the bioaerosol source. When the system is operated, the fan assembly suctions air through the filter positioned at the duct inlet, through the UV sanitizer, and expels the treated air through the manifold orifices which are directed towards the deflector to create an air curtain and negative pressure environment which contains the newly generated bioaerosols directing them to the filter of the in-take assembly.

A siphoning device suited for automatically removing fluid/blood from a surgical site is described, having a length of sterile flexible tubing that is configurable into a loop, the tubing having a first open end, a second open end, and a central portion. A plurality of holes punctuate the circumference of either the first open end or the central portion of the loop, the one or more sets of holes being distributed along a longitudinal direction of the tubing. A sterile absorbent covering encompasses the one or more sets of the plurality of holes, the covering being permeable to bodily fluids. The siphoning device is connected to a vacuum system that generates a negative pressure, causing fluids that have accumulated in the absorbent covering to be withdrawn into the vacuum system. Accordingly, a durable, simple non-gauze system for automatically clearing blood/fluid from a surgical site is described.

A dental suction arrangement which removes saliva and other fluids from a person's oral cavity. The suction arrangement includes a suction tube and an absorption body to be placed in the oral cavity. The suction tube includes a suction part which is arranged in the absorption body and which is equipped with a hole organs or elements communicating with the absorption body. The suction arrangement is made of elastically deformable material in order to adapt to the anatomical shape of the bottom of the mouth.

Apparatus and methods for aerosol removal from the vicinity of a patient's mouth. An apparatus can include a coupling having a proximal end and a distal end, the distal end of the coupling having a first port configured to couple to a suction tube, the coupling further comprising an interior cavity from the proximal end to the first port, a conduit having an interior cavity coupled to the proximal end of the coupling connecting the interior cavity of the coupling to the interior cavity of the conduit, the conduit extending to form a circumferential boundary around an area that is sized to fit inside a patient's mouth, and openings arranged on a surface of the conduit, the openings allowing substances in the vicinity of the openings to enter the conduit, and the openings, the conduit, and the coupling forming a passageway through which substances are evacuated from the patient's mouth.

The present invention provides an apparatus adapted for ejection of material, e.g., saliva, from the mouth of a patient during a dental procedure. The apparatus has at least two distal openings such that material may be ejected simultaneously from at least two locations within the patient's mouth. The invention provides a suction apparatus having a proximal tube, which may couple with a standard waste container apparatus having a suction source.

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 dental retractor for controlling the position of soft tissue within a mouth is disclosed. The dental retractor includes a lip retractor for controlling the position of a lip and a cheek retractor including a pair of arms for controlling the position of a cheek. The dental retractor includes a tongue retractor removably coupled to the dental retractor for controlling the position of a tongue.
