The present invention provides dental amalgam recycling systems, useful for recycling particles from a dental liquid effluent drawn, for example, from a suctioning device.

A device for irrigation of an oral cavity in a patient includes a suction element configured to be disposed in the oral cavity and configured to suction a fluid out of the oral cavity. The suction element also has one or more irrigation outlets configured to irrigate the oral cavity with the fluid. A suction line is fluidly coupled with the suction element and is configured to be fluidly coupled with a vacuum source. An irrigation line is fluidly coupled with the one or more irrigation outlets and is fluidly coupled with a source of the fluid.

An apparatus for pressurizing one or more airways of a user, including: a dental arch mold configured to receive a plurality of teeth, a port which may be at a front face of the dental arch mold, a first nasal pillow, a second nasal pillow, a multi-output air regulator, and a plurality of sensors. The multi-output air regulator and sensors allow the airway pressurization device to sense the pressures in as well as be in independent fluid communication with the port of the dental arch, the first nasal pillow, and the second nasal pillow, such that an equalization of pressures, or a determined pressure differential between each may be obtained.

An oral appliance and a method of making the oral appliance for delivering a medicament to an oral cavity are provided. The method comprises forming a non-porous material into a portion of the oral appliance; and applying a porous material to one or more discrete regions of the portion of the oral appliance to make the one or more discrete regions of the oral appliance porous thereby forming the oral appliance.

Oral gas catheters and methods of inducing gas in a patient orally. The oral gas catheter includes one or more delivery cannulas configured to be inserted into the patient's mouth with a distal end of the delivery cannula disposed adjacent the patient's laryngeal inlet, and a clip disposed on the delivery cannula. The clip is configured to secure the delivery cannula to a tooth of the patient. The oral gas catheter may have two such delivery cannulas and clips with the delivery cannulas coupled together by a coupler. The delivery cannulas are placed in an operative position in a patient's mouth and secured in the operative position by releasably securing the clips to the patient's teeth. The oral gas catheter makes it possible to bypass the nasal cavity and deliver oxygen or other gas directly adjacent the laryngeal entrance and into an anatomical dead space of the airway.

The invention relates to a mouthpiece for a product dispensing device including a product dispensing duct defining a longitudinal axis and including a connection opening designed to be connected to a dispensing member of the product dispensing device, and a dispensing opening designed to open freely into the mouth of a user, and a lingual cavity designed to receive at least one end of the tongue of the user, including a lingual opening allowing the tongue to be inserted into the lingual cavity and a contact surface designed to form a target for one end of the tongue of the user.

The invention also relates to a product dispensing device and to a method for dispensing a product.

A facemask has an outer surface, an inner surface, and a mouthpiece. The inner surface has either a receiver or an insert, and the mouthpiece has either an insert or a receiver that mates with the receiver or the insert of the inner surface. When the receiver and the insert are mated (or coupled), the user can wear the facemask by having the mouthpiece inside the user's mouth.

A positive exhalation pressure device increases the pressure gradient in the airways, thereby increasing oxygen saturation levels and decreasing the severity of hypoxia. Various embodiments of the device may be inserted into the nasal and/or oral cavities, or configured as mask devices covering the nasal and/or oral cavities. In some embodiments, the resistance of the device may be varied.

A syringe finger ring and finger ring inserts, that in various embodiments, provides or connects to a syringe that comprises a syringe body capable of having a volume of material therein and a plunger disposed to enter the syringe body and dispense material from the syringe body by movement of plunger, and a novel a finger ring and related structures having an open area and connected, by various structures, to the plunger adapted to receive a finger within the finger ring open area, including a spacer of various embodiments inserted within the open area to selectively reduce the open area and provide more controllable engagement of the syringe plunger by the operator finger in distal and proximal strokes.

The present invention provides dental amalgam recycling systems, useful for recycling particles from a dental liquid effluent drawn, for example, from a suctioning device.
