Description

"Device for cleaning human and / or artificial and / or animal teeth or system with such a device"

The invention relates to a device for cleaning human and / or artificial and / or animal teeth, with at least one delivery opening for the delivery of an at least partially solid particle abrasive or system with such a device.

Different designs of devices for cleaning human and / or artificial teeth, in particular for dispensing an abrasive, are known in the prior art. The most frequently used device is designed as a fixed station and is provided in dental practices or permanently installed here. The device known under the name “powder jet device” initially has an outer housing and a manually operable oral instrument for the targeted delivery of the powder jet onto the teeth to be cleaned orally. The device known here in the prior art, ie the known “powder jet device”, has an interior its housing has a compressed air chamber and a water supply. The compressed air, ie the blowing agent, and the water, ie the carrier, are brought together and then passed through a "powder chamber" in which quartz sand - as blasting agent - is stored. The fact that the blowing agent / carrier agent mixture is the blasting agent passes through "powder chamber", it takes parts of the quartz sand with it, in which case the resulting blowing agent / carrier / quartz sand mixture, also generally called "aerosol", via a hose to the oral

Instrument is guided. "Powder jet devices" are also known which can be moved from one treatment room to the other, but must be connected via coupling elements to the water and compressed air supply permanently installed in a practice.

The powder jet devices known in the prior art are not yet optimally designed. On the one hand, these are only installed in a fixed position in a dental office, on the other hand, they can only be operated by an expert, namely the dentist himself or an expert helper become. Further powder jet devices are designed such that they have to be connected to the fixed compressed air supply or water supply provided in a dental practice. The known powder jet devices are thus permanently installed in a treatment room or have to be moved and connected in a complicated manner. For example, dental surgeries have to install a corresponding powder jet device in almost every treatment room, which is very expensive. The amount of work and the associated labor costs to connect the mobile powder jet devices are also very high. The treatment for the corresponding oral cleaning of the teeth is therefore associated with a correspondingly high cost.

The invention is therefore based on the object of designing and developing a device of the type mentioned at the outset such that the costs for cleaning the human, artificial and / or animal teeth are reduced, in particular the flexibility of the device is increased and vzw. a human user can clean his teeth without outside help.

The object outlined above is now achieved in that the device is designed essentially as a manually operable and / or compactly designed, location-independent, mobile spray device for the targeted delivery of the blasting agent. Because the entire device is now essentially configured as a manually operable spray device, the device can now be operated regardless of location or regardless of location and can, for example. be available at all times on the counter, even in the user's bathroom. Furthermore, the spray device vzw. a spray head, which is designed so that a targeted delivery of the abrasive is made possible in the direction of the teeth to be cleaned. With such a device, the teeth of the user, both in the oral area, and possibly artificial teeth of the user, vzw. Dentures or the like, and even the teeth of animals, especially dogs, etc., be cleaned well. The abrasive, which vzw as solid particles. has corresponding grinding element elements, can be applied in a targeted manner to the corresponding teeth by the user himself, the abrasive or the abrasive elements contained in the abrasive remove or take away the corresponding dirt particles that have deposited on the surfaces of the teeth. The device according to the invention is now essentially independent of location, namely in the form of a mobile spray device. This means that the spray device according to the invention is no longer - as was previously the case - permanently installed in the treatment room of a dental practice, but can be used variably. This reduces - at least for dentists - corresponding acquisition costs for the respective devices. As a result, the disadvantages described at the beginning are therefore avoided and corresponding advantages are achieved, in particular simple and inexpensive handling of the device or inexpensive cleaning of the teeth is also made possible by the user himself, which will be made clear below.

There are now different possibilities for designing and developing the device according to the invention in an advantageous manner. For this purpose, reference may first be made to the claims subordinate to claim 1. Several preferred embodiments of the invention will now be explained in more detail below with reference to the following drawing and the associated description. The drawing shows:

11c shows a ninth embodiment of the device according to the invention with a specifically designed spray head in schematic representations from the side, from above and from the front, and Fig. 12 shows a system according to the invention with a corresponding device according to the invention in a schematic perspective view.

1 to 12 show a device 1 for cleaning human and / or artificial teeth. Here, both teeth in the oral area of the user may be meant, that is, human and natural teeth, as well as artificial teeth, that is, dentures, bridges, artificial teeth implanted in the jaw, etc. With the device 1 described here, an intraoral cleaning of teeth is therefore conceivable or possible, as well as an extra-oral cleaning of teeth, namely, for example, the cleaning of dentures removed from the mouth. Finally, with the devices 1 described here, it is not only possible to clean human teeth, but also animal teeth. For example. a user can clean his dog's teeth in a simple and inexpensive manner, in particular you no longer have to go to the veterinarian with the animal, in particular the dog, in order to have the teeth cleaned by the veterinarian in a cost-intensive manner.

The disadvantages described at the outset are now avoided in that the device 1 is essentially designed as a manually operable and / or compactly designed, location-independent, mobile spray device la for the targeted delivery of the blasting agent 3. There are now several options for designing and developing the device 1 according to the invention. This will be explained in more detail below. As a result, however, all devices 1 according to the invention, namely the spray devices 1 a, have in common that they can be used very flexibly and that the teeth of the user and / or animals are cleaned in a cost-effective manner.

Fig. 1 shows a first embodiment for the. Device 1, namely a can-shaped pressure vessel lb with a spray head 2, an interior 4, a riser 5, a vzw. in the spray head 2 arranged valve element 6, at the end of which the corresponding discharge opening 2a is formed. Vzw. are the valve element 6 and the discharge opening 2a are components of the spray head 2. In the device 1 shown in FIG. 1, a cover element 7 is also provided to protect the spray head 2 when the spray device 1 a is not in use.

Fig. 2 shows a second embodiment of the device 1. In this embodiment, the spray head 2 is designed differently than the spray head 2 of the device 1 in Fig. 1. Namely, the spray head 2 has a target tube 8, the end of the target tube 8 the Dispensing opening 2a forms. A further peculiarity of the second embodiment shown in FIG. 2 is that a separate storage space 9 is additionally provided externally from the interior 4 of the can-shaped pressure container 1b.

FIG. 3 shows a third embodiment of the device 1, namely a can-shaped pressure container 1b which has two chambers 15 and 16. The first chamber 15 and the second chamber 16 enable the substances stored in the can-shaped pressure container 1b to be separated. So vzw. in the chamber 15 the carrier means 11 and in the second chamber 16 the blasting agent 3 is stored. If the spray device 1 a shown here is used, a flow connection between the first chamber 15 and the second chamber 16 is established beforehand. Vzw. For this purpose, an adjusting screw 17 is actuated, so that the wall 18, which separates the first chamber 15 from the second chamber 16, is at least partially destroyed and / or displaced in such a way that a flow connection is established between the first chamber 15 and the second chamber 16 is.

FIG. 4 shows a fourth embodiment of the spray device 1 a with a target tube 8. The pressure container 1 b designed here in a can is essentially constructed in such a way that it has two movable components that can be moved one inside the other. The pressure container lb is a kind of pump

Device designed so that the pressure within the can-shaped container 1b can be generated or increased by pumping movements, that is to say by movements of the two movable components. As a result, a blowing agent, in particular, does not necessarily have to be in this interior 4 of the pressure container 1b no propellant gas is provided, but the pressure required for the spraying actions can be built up manually by the appropriate movements.

FIG. 5 shows a spray device 1 a which has two can-shaped pressure containers 1 b and a mixing chamber 19. The two can-shaped pressure containers 1b, the respective risers 5 and the mixing chamber 19 can be clearly seen here. By actuating the spray heads 2, namely by corresponding manual pressing, corresponding valve elements 6 open, so that the corresponding substances are brought together in the mixing chamber 19, namely vzw. the carrier means 11 is led out of the first pressure container 1b and the blasting agent / or propellant mixture “3, 10” is led out of the second container 1b and is mixed with one another in the mixing chamber 19 before it is dispensed via the discharge opening 2a.

1 to 3 and FIG. 5 show the preferred embodiments according to the invention. The preferred basic idea of the invention is to design a corresponding device 1 as a “spray can”, that is to say as a spray device la in the form of a can. As shown in FIGS. 1 to 3 and FIG. 5, a can-shaped pressure container 1b or two can be used can-shaped

Pressure vessels lb are provided. In principle, it is conceivable that only the blasting agent 3 and the propellant 10 are provided in the interior 4 of a can-shaped container 1b, that is to say the spray device 1 a is functional without the carrier means 11. Vzw. however, the carrier 11 is additionally added, in particular for the user this is also "refreshing" for oral hygiene. Such can-shaped pressure containers 1b can have corresponding stirring elements which, if the can-shaped pressure containers 1b are shaken accordingly, for a good mixing of the respective ones Provide substances provided in the interior 4. Such “spray cans” can be made, for example, of aluminum or tinplate.

FIG. 6 shows a further embodiment of a spray device 1 a, which is designed as a type of spray gun. For this purpose, the spray device la two pressure containers 1b designed as print cartridges, which can be clearly seen in FIG. 7.

Finally, FIGS. 8 and 9 and 10 show spray devices 1 a, which are designed as a kind of oral irrigator.

The functioning of the spray devices 1 a shown in FIGS. 1 to 10 will now be explained in more detail below:

First of all, the following may be carried out in relation to FIG. 1:

Pressure vessel lb is a propellant 10, vzw. a propellant gas is provided. Furthermore, a carrier means 11, vzw. Water provided. Finally, the blasting agent 3 is provided in the interior 4 of the pressure container 1b. The blasting agent “3”, the blowing agent “10” and the carrier means “11” are shown here schematically, as in the following, with “numbers in circles”. As a result, a mixture of propellant 10, carrier means 11 and blasting agent 3 is thus provided in the interior 4 of the pressure container 1b. The pressurized pressure container lb, namely the vzw. mixture under a pressure of 6 to 8 bar can now be sprayed accordingly with the aid of the spray head 2. In the area of the spray head 2, a manually operable valve element 6 is provided for closing or opening the flow connection between the discharge opening 2a and the pressure container 1b.

In the embodiment shown in FIG. 1, the valve element 6 can be opened by manually pressing the spray head 2 from above. Vzw. the discharge opening 2a is designed as a nozzle-shaped outlet opening of the spray head 2. As blasting agent 3 for the embodiment shown in FIG. 1, vzw. Aluminum oxides (A2O3) in question. As a carrier 11 for transporting the blasting agent 3 come vzw. Water or aqueous solutions can be considered, suitable propellants 10 being suitable as blowing agents, which will be explained in the following. Other substances in the interior 4 of the pressure container 1b can be disinfectants, flavoring substances such as mint oils or the like. This depends on the respective application. In operation increases So when the spray head 2 is actuated, the blowing agent / carrier / blasting agent mixture passes through the riser pipe 5, passes through the valve element 6 and is sprayed onto the teeth to be cleaned via the discharge opening 2a.

The following may be stated in connection with FIG. 2: FIG. 2 shows a second embodiment of the device 1, vzw. a differently designed spray head 2. The device 1 shown here thus consists of a pressure container 1b, the spray head 2, the spray head 2 having an additional storage space 9, namely for storing the blasting agent 3. In the interior 4 of the pressure vessel lb are therefore vzw. only the propellant 10 or the carrier means 11 are provided or stored. The spray head 2 here also has a schematically indicated valve element 6 and a riser pipe 5. Furthermore, the spray head 2 has a target tube 8, which has a nozzle-shaped delivery opening 2a at its end in order to ensure targeted delivery of the mixture onto the teeth.

In the device 1 shown in FIG. 2, namely the spray device 1 a, when the spray head 2 is actuated, a propellant / carrier agent mixture is first dispensed via the riser pipe 5 and the valve element 6 into the separate storage space 9. Here the blowing agent / carrier mixture then takes components of the abrasive 3 stored here, so that the corresponding blasting agent / blowing agent / carrier mixture is then dispensed via the target tube 8. It is also conceivable that a mixing chamber is provided between the additional storage space 9 and the pressure container 1b. This depends on the specific application. The separation / separation of the blasting agent 3 from the carrier means 11 is particularly advantageous here, since it avoids the risk of clumping and / or blockages, in particular in the period when the spray device 1 a is not being used.

Fig. 3 shows a third embodiment of a can-shaped pressure container lb. As already mentioned above, the can-shaped pressure container 1b has a spray head 2, a riser pipe 5 and two chambers, namely a first chamber 15 and a second chamber 16. The two the chambers 15 and 16 are separated by a wall 18. With the exception of the two chambers 15 and 16 and the adjusting screw 17, the embodiment shown in FIG. 3 is configured similarly to the embodiment shown in FIG. 1. However, in the embodiment shown in FIG. 3 it is advantageous that here a separation / separation of the carrier means 11 and the blasting agent

3 is realized. The blasting agent 3 is vzw. in the second chamber 16 and the carrier means 11 vzw. provided in the first chamber 15. Before using the spray device 1 a, the wall 18 is pierced accordingly by means of the adjusting screw 17 and / or shifted such that a flow connection between the first chamber 15 and the second chamber 16 is ensured. Only then can the corresponding mixture of substances, ie the mixture of blowing agent / carrier / blasting agent, be dispensed via the spray head 2 or the discharge opening 2a via the riser 5. Of particular advantage in the embodiment shown here is that clumping and / or clogging - before using the spray device 1 a - is avoided by separating the corresponding substances.

Fig. 4 shows a fourth embodiment of a spray device la. The target tube 8 and the can-shaped pressure container 1b, which is formed here in two parts, namely an upper part and a lower part, which are arranged so as to be movable relative to one another, can be clearly seen. Because these components can be moved, quasi "propellant gas", namely the ambient air, can be pumped into the interior 4 of the pressure container 1b via a valve element (not shown). If a corresponding pressure is built up, the corresponding valve elements and a trigger button (not shown here) can then be used Blowing agent / carrier / blasting agent mixture are dispensed via the target tube 8. The principle shown here works similarly to the known pump water guns.

5 shows a further spraying device 1 a, which has two pressure containers 1 b, namely a first pressure container 1 b, which only has the carrier means 11 and a second pressure container 1 b, which has the propellant 10 and the blasting medium 3. Only when the spray device la is actuated do the respective substances rise above the corresponding risers 5 and become in one Mixing chamber 19 is mixed and the substance mixture can then be dispensed via the target tube 8 or the dispensing opening 2a. Vzw. the supply lines to the mixing chamber 19 are equipped with corresponding valve elements (not specified in more detail), which are designed in particular as rotary closures, so that a controlled supply of the blasting medium 3 or propellant 10 and the

Carrier 11 is guaranteed.

Fig. 6 shows a further embodiment for a spray device la. The embodiment shown here is vzw. Designed as a kind of spray gun, it has a handle 13 and a trigger 14. It's easy to see

Target tube 8 and other flow connections as well as the separate storage space 9 and a valve element 6, which is arranged between the pressure container 1b and the discharge opening 2a.

FIG. 7 shows the spray device 1 a shown in FIG. 6 from above.

Two pressure containers 1b and two valve elements 6, which can be controlled via the corresponding trigger 14 with the aid of an actuating linkage, which is not described in any more detail, can be clearly seen here. Furthermore, the corresponding fluid lines can be clearly seen in FIG. 7. In the first upper pressure container lb is vzw. Compressed air, i.e. the propellant 10 is stored. In the lower pressure container lb is vzw. the carrier 11 is stored. The pressure containers 1b shown here are designed as so-called "cartridges", whereby a "CO 2 cartridge" can also be used. When actuated, ie in the application, the valve elements 6 are opened via the trigger 14. The corresponding propellant 10, vzw. the carbon dioxide / oxygen mixture from the pressure container 1b and is guided over the storage room 9, where it takes the blasting agent 3 to the discharge opening 2a. It is also conceivable here that a corresponding mixing chamber can be provided. However, in the embodiment shown here, the blasting agent 3, the blowing agent 10 and the carrier means 11 are brought together here shortly before the discharge opening 2a via corresponding flow lines. It is also conceivable that only one pressure container 1b with propellant 10 and carrier means 11 is provided. In particular in the embodiments shown in FIGS. 5 to 7, two pressure containers 1b are provided are in the pressure container lb, where the carrier 11 is stored, also here additionally vzw. a blowing agent 10 is also provided so that the carrier

11 can also leave the corresponding pressure container lb well.

8 and 9 now show a further embodiment of a spray

Device la, which is designed here as a kind of oral irrigator. The corresponding spray device la has a housing 12 and is relatively compact. In addition, a mini compressor 20 and a carrier medium storage container 21 are provided in the housing 12. The corresponding pressure, vzw. Compressed air generated. This is led via appropriate flow connections to a separate storage room 9, which is arranged here above the housing 12, but also in the housing

12 can be arranged. The propellant 10 then takes the corresponding abrasive 3 stored here in the storage room 9, mixing between the propellant / abrasive mixture and the carrier 11 being realized via corresponding flow lines. Vzw. The spray device 1 shown here also has a pump (not shown in more detail) for conveying the carrier 11 from the carrier reservoir 21 via the corresponding flow line to the discharge opening 2a. The compact spray device 1 a shown here is vzw. electrically operated and in everyone

Bathroom placeable. Vzw. Correspondingly long connecting hoses are provided for optimal handling. The user can optimally clean his teeth with this.

Finally, FIGS. 10 and 10a and 10b at least partially show a further embodiment of a spray device la. The spray device 1 a shown here can also be operated manually. A corresponding carrier connection 22 is necessary only for operation, here vzw. a water connection. However, a high degree of flexibility of the spray device 1 a, ie essentially location-independent and mobile use, is possible via correspondingly long connecting hoses. The propellant 10 provided by a mini-compressor 20 can then be guided to a separate storage room 9 via appropriate fluid lines, where the abrasive 3 is stored. When the propellant 10 is carried through the storage space 9 the propellant 10 takes corresponding solid particles of the abrasive 3 with it, so that the resulting propellant / abrasive mixture can then be combined with the carrier 11 accordingly.

As FIGS. 10a and 10b show, this can be controlled accordingly via corresponding flow branches or flow mergers and corresponding valve elements 23 arranged here. It is conceivable here that the oral instrument, that is to say the target tube 8, is of single-tube or double-tube design, depending on when a corresponding combination of the individual substances is to take place relatively far in front of the discharge opening 2a or only in the region of the discharge opening 2a.

11a to 11c show at least partially in a schematic representation the device 1 designed as a spray device la according to the invention. The spray device 1 a shown here also has a pressure container 1 b and a spray head 2. The spray head 2 has a finger support surface 24, which vzw. has a relief-like structure to increase the contact force when a corresponding finger is placed on the finger support surface 24. As in particular FIGS. 11a and 11c show, the finger support surface 24 is vzw. trough-shaped, so that a corresponding finger on the

Finger support surface 24 can be placed. The delivery opening 2a, which vzw. is nozzle-shaped and is formed at the corresponding end of a target tube 8. Functionally, the spray device 1 a, which is shown in FIGS. 11 a to 11 c, is essentially designed in the same way as the device 1 shown in FIGS. 1 to 3.

Device la is here vzw. also designed as a spray can or aerosol can.

As can be seen from FIGS. 11a to 11c, a splash protection element 25 is provided in the peripheral region of the discharge opening 2a. The splash protection element 25 surrounds the discharge opening 2a vzw. complete and is designed such that it can be inserted into the mouth of a user. In other words, for the corresponding oral application, the lips of the user enclose the splash protection element 25, which here vzw. is funnel-shaped. With the in the 11a to 11c trained spray device la, the user can now easily clean his teeth by the vzw. funnel-shaped spray protection element 25 encloses with its lips and presses with one of its fingers on the spray head 2, so that the valve element (not shown here) opens and the blasting agent, propellant and / or carrier agent

Mixture or the tooth spray composition can reach the oral area of the user via the discharge opening 2 a from the spray device 1 a.

In the embodiments shown in FIGS. 1 to 11, three different substances come into consideration as blasting means, vzw. Aluminum oxides (corundum,

Bauxite), silicon oxides such as quartz sand powder and / or grinding, sodium carbonate or sodium bicarbonate, as well as various types of powder, namely nutshell powder, corn cob powder or olive kernel powder. Sprot, shavings, flour and various filings made from these materials are also conceivable. In addition, 3 substances such as glass beads, ceramic beads and / or come as blasting media

As a propellant 10 come vzw. CFC substances and / or gases such as butane, propane, propene, nitrogen, oxygen, carbon dioxide and / or compressed air or mixtures of the gases mentioned. Furthermore, additional substances such as disinfectants, in particular alcohols and / or flavorings such as menthol oils, citrus oil or the like, can be provided or added in the pressure container 1b. Furthermore, preservatives are also conceivable, namely that they are introduced into the corresponding mixture of substances, as are oral disinfectants or mouthwashes. In particular for the spray can-like embodiments of the invention, vzw. where there is a corresponding mixture of substances in the interior 4 of a pressure container 1b, the following mixing ratios have proven to be particularly advantageous, in particular for the tooth spray composition: 16 ° Celsius to 25 °

Celsius following volume percentages, namely for the carrier 11 (vzw. Demineralized water) vzw. 40 to 60 or in particular 4 to 30 percent by volume, for the propellant 10 (vzw. Propane or butane) vzw. 15 to 20 percent by volume, for the blasting agent 3 (vzw. Aluminum oxide) vzw. 15 to 30 or even 30 to 50 percent by volume. Furthermore, other additives can be added, especially disinfectants such as vzw. Alcohols from vzw. 15 to 20 percent by volume and essential oils as flavorings from vzw. less than 5 percent by volume.

It is crucial that the mixture escaping through the discharge opening 2a has at least one blasting agent 3 which vzw solid particles. Contains abrasive elements so that the protective particles deposited on the surface of the teeth, for example the dental plaque and / or the tartar, can be easily removed, the device 1 being designed such that it is manually sprayed by the user as a spray device la can be operated so that the most cost-effective treatment possible for the user is made possible without the help of specialist personnel. The disadvantages described above are thus avoided.

In particular, a device 1 with a “tooth spray composition” is specified here, which can also be designated as a “kit”. The entire apparatus, ie the kit, is used for cleaning human and / or artificial and / or animal teeth. For this purpose, the "kit" is used to clean human and / or artificial and / or animal teeth and comprises a tooth spray composition which is provided accordingly in the device 1, in particular within the spray device la. The spray device la, which is also known as "Spray-dispenser system" could be called, contains the corresponding tooth spray composition for cleaning the above-mentioned human and / or artificial and / or animal see teeth. In the following, vzw can now be added to this tooth spray composition. do the following:
