Definitions
- the invention relates to a dental treatment and preparation unit for in particular tubeless and cordless handpieces or the like, which contain at least one reservoir for a cooling medium for the treatment site and at least one energy source.
- Dental treatment places of the type in question have long been known from practice and exist in a wide variety of designs.
- handpieces are operated with turbines and / or air motors and / or electric motors, in particular for drilling, milling and grinding.
- Curing lamps are also often used. Larger amounts of air are required to operate and cool these components. In particular, a large amount of air is required to cool the processing point in or on the tooth by means of a spray containing a lot of air. This requires a powerful compressor. Furthermore, powerful suction machines and separators are required to
- the invention is therefore based on the object of a dental treatment station
- REPLACEMENT BLADE (RE6EL 26) Specify, in which a simple, space-saving, ergonomically optimal and inexpensive construction with a very simplified supply and disposal is realized.
- the treatment place contains means, without
- Wastewater pipes the usual patient treatment of drilling, grinding,
- the handpieces are expediently arranged in the grip area of the doctor, preferably on a tray. It is also advantageous if a processing unit (charging device) is available that connects the handpieces to the
- the invention can be designed in such a way that cleaning and / or disinfection and / or sterilization and / or lubrication and / or other care of the handpieces takes place in the processing unit. It is advantageous if a charging device for the hose-free and cordless handpieces is attached to one
- Pressure source for air and / or a pressure source for water and / or connected to a sewage pipe is a pressure source for air and / or connected to a sewage pipe.
- the charging device is expediently supplied with electricity and connected to a pressure source for air and / or a pressure source for water and / or to a sewage line or generates the pressures from the ambient air and the
- the charging device can at least have a socket for receiving a counter socket of a hand-held device, which is connected to the pressure source and / or to a source of electrical energy for recharging the reservoirs present in the handpiece. It is also advisable to couple the charger with a source of warm pressurized water.
- the treatment unit comprises a suction system with a collecting container for waste water and waste.
- the suction system can advantageously have a cannula with a variable lumen. It is also recommended that the collecting container expediently has an exchangeable filter made of hydrophobic material.
- the processing unit can comprise a separating system for separating liquids and solids, preferably amalgam.
- a separating system for separating liquids and solids, preferably amalgam.
- an evaporation device for the liquid is recommended, which can be implemented, for example, by a microwave generator for a mixture of liquid and solid contained in a vessel.
- the separating system is expediently arranged behind an advantageously microwave-tight flap.
- the processing unit can also be designed in such a way that a spittoon is attached to a telescopic support arm and is assigned a suction cannula.
- At least one handpiece has a reservoir for the energy and / or the gas and / or the
- the handpiece is thus supplied with operating media in a self-sufficient manner. This in turn means that no more complex hose and / or cable connections are required at the dental treatment station. Furthermore, powerful compressors or other supply units, which are usually used via hose or the handpieces
- the treatment station according to the invention specifies a treatment station in which a simple, space-saving and inexpensive construction is implemented.
- the gas could be air and / or the liquid could be water.
- Air and / or water are particularly suitable as coolants for a treatment site.
- a spray with water that contains a lot of air is used for cooling.
- large amounts of water to be disposed of are obtained, a large part of the water as a spray not directly reaching the treatment site for cooling, but rather being sprayed unused onto areas surrounding the treatment site.
- the air carries the resulting aerosol cloud into the treatment room and contaminates it.
- pure liquid cooling could be used, in which the liquid, for example water, is led directly to the treatment site.
- the liquid for example water
- liquid can be directed better at the treatment site, a significantly smaller amount of liquid must be used for a comparable cooling effect than in spray cooling. Such a pure liquid cooling therefore also results in a considerably smaller amount of liquid to be disposed of. This reduces the outlay in terms of apparatus for liquid removal and disposal.
- the reservoir could be a pressure and / or thermal container. This would make it possible to supply a preheated operating and / or cooling medium to the treatment site.
- the design of the handpiece or handpieces with a reservoir for the operating and / or cooling medium enables the handpieces to be operated without a permanent supply to the handpieces by means of a cable or hose connection.
- the treatment station according to the invention could have a suction system for extracting air and / or saliva and / or removal.
- the suction system could be dimensioned considerably smaller when using pure liquid cooling than conventional suction systems with spray cooling.
- the amount of coolant that occurs in the mouth during liquid cooling can be removed with a suction system that only has the capacity of a conventional saliva ejector. Since the resulting drilling waste requires greater suction power and possibly larger lumens of the suction cannula than the saliva ejector offers, the suction system could be designed to operate at least two differently dimensioned cannulas and / or with different suction powers. For removing drilling waste or for others
- the suction system could have a cannula with a variable lumen.
- the cannula could be so flexible that it allows a lower suction volume in the curved state than in the extended state.
- it could serve as a saliva ejector in the curved state and as a suction cannula for drilling waste in the stretched state.
- the suction system could have a pump or a blower. With a view to adapting to different suction requirements, the pump or the blower could have at least two switchable power levels.
- the cannula could be connected to a container via a connecting device, preferably a hose.
- the pump or the blower could be assigned to the container.
- line losses with regard to the suction power via hoses and the like are avoided.
- the pump or the blower in the simplest case a fan, could start automatically and air.
- An air-permeable, preferably exchangeable filter could be assigned to the container for removing air.
- the container could be closed with the filter at the top.
- the filter could be air, but not
- the filter could be made from a hydrophobic material in a particularly hygienic and simple manner.
- the filter could be made as a fine-mesh grid, for example made of polypropylene.
- the container could be removable from the suction system. It could thus be removed from the suction system or removed from the suction system when it is filled. The container could then be disposed of in the manner customary in the country and / or in practice. Disposal as special waste, via separate amalgam separators, into a sink, into a toilet or into a trash can is conceivable. Finally, a replacement container or the empty container could be assigned to the suction system again.
- the suction system could be attachable to an arm for holding a tray for, for example, dental instruments.
- the container and the pump or the blower could be attachable to the tray arm.
- the cannula either a single cannula or a larger one Suction power switchable cannula, would be attached to the suction system in its rest position.
- the treatment station could have a separating system for separating liquids and solids, in particular amalgam. So far, sedimentation containers, centrifuges and larger chunk sieves have been used for amalgam separation. The principle of operation of these separators is particularly suitable when solids are transported in large quantities of coolant. All of these principles can of course also be used with smaller amounts of coolant, including those described here
- filtering could take place using appropriately fine filters. Since filters with biological fluid clog very quickly, filters are not suitable for continuously operating amalgam separators. Disposable filters, on the other hand, are well suited.
- the collected coolant or waste water could be cleaned with solids via a filter, which can be similar to a coffee filter. The coolant could simply be run through or accelerated by suction or pressure. The cleaned coolant then flows into the drain, whereas the filter is removed periodically and its contents disposed of.
- the separating system could have an evaporation device, one being the evaporation device
- Heating coil or a microwave generator could be provided.
- the liquid is heated and the water or coolant and / or detergent evaporates.
- the steam could be discharged into the drain.
- a fan could be provided for this.
- the drain could be equipped with a non-return valve that prevents odors from escaping. When the evaporation container is filled, it is removed, closed and disposed of. Alternatively, only its dry contents could be disposed of.
- a handpiece to which a drying device is assigned, could be provided for drying a treatment site.
- the drying device could be integrated into the handpiece or be detachably attached to the handpiece. It is essential here that the handpiece can be operated virtually independently and has no mandatory hose and / or cable connections to a supply device.
- the drying device could have an electrically operated hot air blower.
- the electrical supply of the warm air blower could take place via a suitable storage for electrical energy, for example an accumulator.
- the drying device could have a device for surge operation.
- the handpiece could be used as a chip blower.
- the dental treatment station could have a handpiece with a two-media syringe assigned to the handpiece, each with a reservoir for a liquid and a gas.
- the two media syringe could be integrated into the handpiece or detachably attached to the handpiece.
- the gas could be air and / or the liquid could be water.
- the drying device and the two-media syringe could be assigned to one and the same handpiece.
- the drying device and the two-media syringe could be attached to the handpiece or integrated into the handpiece.
- the drying device could have a cordless, blow dryer-like warm air blower that can be externally disinfected or sterilized.

- a handpiece with a tartar remover with a water cooling device could be provided.
- the water cooling device could have a rechargeable reservoir and conveying devices.
- a charging device could be provided for the handpiece (s).
- the charging device could be formed by a separate device, which is arranged, for example, behind the treatment chair and thus behind the patient's head. This would result in particularly short distances for reloading with operating media.
- the charging device could also be designed for the care and / or cleaning and / or disinfection and / or sterilization of the handpieces. Furthermore, the charging device could be designed to supply operating media warm to the body in the reservoir or reservoirs. It is particularly advantageous here if the affected reservoir is a thermal container. For example, water, however, any other operating medium, filled with body heat from the loading device into the corresponding reservoirs and kept thermally insulated there.
- the charging device could have means that are suitable for charging the tubeless handpieces with the necessary media by plugging them onto a nozzle.
- electrical media, compressed air and coolants, for example water can be used as media.
- the charging device could have means for cooling the handpieces, for example to dissipate heat loss from the motors. Such means could be coupled to the nozzle.
- the charging device could have a heating device that heats the handpieces to a predefinable temperature, for example hand temperature.
- the charging device could have at least one quick-charging port, via which gas and / or liquid can be recharged for a very short time.
- the treatment chair could only have an electrical connection.
- the dentist element with hand-held handpieces that are usually hose-bound could also be dispensed with.
- it could also be a large suction cannula, common today
