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.

A saliva aspirator having an injection moulded plastic component forming a coupling for connection to a suction hose, optionally via an adapter. A plastic moulded part is manufactured as a multi-component injection moulded part and forms a plastic component which is harder than another plastic component, the hard component, the coupling and optionally the adapter. The other plastic component, the soft or flexible component, forms a suction area with at least one suction opening or suction pore for saliva and an outlet opening towards the suction hose and consists in particular of an open-pored, preferably thermoplastic, elastomer.

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.

A compact extraoral suction passage tip to help protect a dentist from infectious materials. The compact extraoral suction passage tip is made of an internal suction passage. The proximal end can be slid into a High Volume Evacuator (HVE) valve or other suctioning device, and the distal end can be placed near a patient's mouth to collect infectious materials and placed in a position that will not significantly impede dental operations. The distal end is shaped so that it can lie on or near the upper portion of a patient's bottom lip to provide suction capability. One embodiment contains ridges to help patients know where to hold the compact extraoral suction passage tip.

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.

Dental instrument assemblies (e.g., mouth pieces, bite blocks, vacuum dental mirrors, illuminated dental mirrors, illuminated dental wedges, trans-illumination dental instrument, illuminated dental bite blocks, etc.) are provided. The dental instrument assemblies may be adapted to be periodically sterilized. The dental instrument assemblies may include a magnetically energetic fiber optic coupler. The magnetically energetic fiber optic coupler may be configured to allow dental instrument adapter to rotate with respect to an associated fiber optic cable that is removably connected to the magnetically energetic fiber optic coupler. The dental instrument assemblies may include a fiber optic material that is encapsulated.

The invention relates to a suction device for intraoral use, comprising a suction line and a tongue protection, said suction line being bent substantially U-shaped, which are configured by a molded part, in particular integrally with one another. The suction tube comprises a connection which points mesially for a suction hose. In the course of the suction tube the connection is adjoined by an upper U-leg, a mesial U-central portion and a lower U-leg, said legs extending distally from the U-central portion. The lower U-leg comprises suction openings and is surrounded by a suction sponge which covers the suction openings. The suction tube terminates at the distal end of the lower U-leg in an end suction opening which is covered by the suction sponge.

A dental device to be placed in the oral cavity between the lower teeth and the tongue for use as a combined saliva/fluids ejector and tongue deflector/retractor in dental treatments, comprising: a substantially flat head portion with hollow tubing on a portion of its periphery, and suction holes (preferably oval-shaped and protected from soft tissue entrapment by raised ribs) and in communication with the hollow tubing; a body portion provided with a bore and a ratchet mechanism, the bore in communication at its upper end with the hollow tubing and at its lower end with a suction system; and an arm having a collar adapted to adjustably engage with and disengage from the teeth of the ratchet mechanism. The cross sections of the collar and ratchet mechanism portion of the body are essentially square in shape.

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.
