A transportable autonomous dental unit is described, mounted on a base to which side walls are associated in order to create a container of around 4 liters of volume, featuring a dental chair whose column has a compressed air tank, a complete instrument table, a compressor to fill the needs of the pneumatic peripherals and venturi suction device for compressed air, means for connection to a water supply line, a wastewater drainage duct, and a power source, offering the same operation conditions of a complete conventional dental unit.

Disclosed is a system for providing artificial saliva. The system can include the mouthpiece, a portable supply unit, and a stationary supply unit. The portable supply unit can be adapted to be carried by a user. The portable supply unit can include a first fluid system, a first interface module, and a first control module. The first fluid system can be adapted to fluidly couple to the mouthpiece.

The present invention provides a snap-on cap that is useful with containers, and in particular, collection containers useful for dental amalgam recycling systems. The snap-on cap is useful for shipping and recycling of particles from a dental liquid effluent drawn, for example, from a suctioning device.

An oral hygiene apparatus in the form of a fixture to provide a controllable pressurized water stream for cleansing the gums and teeth, especially in the interdental area, of a user. The hygiene apparatus may essentially comprise three parts including a water supply, an oral hygiene-ware and a water utility.

A dental valve device having a disposable turret is disclosed having a valve body having a tip receiving end, a hose receiving end, a lumen formed between the tip receiving end and the hose receiving end, an opening formed in the valve body, and a rotatable valve sealing body adapted to being inserted into the opening, the rotatable valve sealing body having a bore for alignment with the lumen formed between the tip receiving end and the hose receiving end, the bore having a tip receiving end opening and a hose receiving end opening, the rotatable valve sealing body having an outer surface having an indentation formed in the outer surface adjacent to the tip receiving end opening with the indentation having an upper ramp portion, a lower ramp portion, and an end having a tab portion.

An oral cavity washing device according to the present disclosure includes: a nozzle having a flow passage structure including a flow passage that includes an inlet port and an outlet port; and a pump to feed washing liquid to the inlet port such that a flow rate of the washing liquid ejected from the outlet port falls within a range of 200 mL/min to 350 mL/min. The flow passage structure includes a first component, a reducer, and a second component. The first component, the reducer, and the second component are configured to generate cavitation in the washing liquid flowing through the flow passage when the flow rate of the washing liquid ejected from the outlet port falls within the range of 200 mL/min to 350 mL/min.

An oral cavity washing device includes a nozzle having a flow passage structure and a pump to feed washing liquid to the flow passage structure. The flow passage structure includes: a first component having a first flow passage; a second component being disposed downstream of the first component and having a second flow passage that is narrower than the first flow passage; a third component being disposed downstream of the second component and having a third flow passage that is broader than the second flow passage; a reducer being disposed downstream of the third component and being configured so as to reduce a width of the flow passage; and a fourth component being disposed downstream of the reducer and having a fourth flow passage that widens with an advancement in a path from the reducer to the outlet port so as to generate cavitation in the washing liquid.

A dental valve device having a disposable turret is disclosed having a valve body having a tip receiving end, a hose receiving end, a lumen formed between the tip receiving end and the hose receiving end, an opening formed in the valve body, and a rotatable valve sealing body adapted to being inserted into the opening, the rotatable valve sealing body having a bore for alignment with the lumen formed between the tip receiving end and the hose receiving end, the bore having a tip receiving end opening and a hose receiving end opening, the rotatable valve sealing body having an outer surface having an indentation formed in the outer surface adjacent to the tip receiving end opening with the indentation having an upper ramp portion, a lower ramp portion, and an end having a tab portion.

An oral cavity washing device includes: a body unit including a tank which stores a washing liquid, a pump from which the washing liquid stored in the tank is discharged, and a case formed by joining a plurality of parts to each other so as to accommodate the pump; a tube connected to the body unit so as to make the discharged washing liquid flow through the tube; and a washing unit connected to the tube so as to discharge the washing liquid. The oral cavity washing device includes a seal structure having at least a first seal portion which seals a joint portion between the plurality of parts on an outer shell of the case. With such a configuration, the body unit of the oral cavity washing device can be efficiently washed.

The invention relates to portable devices for collecting small items of waste. A portable container is used, into which a disposable vessel, such as a cup, can be inserted and secured. The container consists of a rigid housing having upper and lower flip lids with seals. The upper lid further has a funnel opening, and the inside part of the container housing has a conical shape, the diameter of the lower inside part of the container housing being smaller than the diameter of the upper inside part, and also smaller than the diameter of the base of a disposable cup. The bottom of the lower part of the container housing has a hole, and the lower lid tightly closes the hole in the bottom of the container housing. The device makes it possible to collect small items of waste in a sealingly closable replaceable disposable vessel, while protecting same against deformation and damage.
