WO2017220064A1 - Device for aspiration of saliva, dental treatment, dental hygiene and cleaning of the tongue - Google Patents

Abstract

The disadvantages of the known saliva aspirator are the strong draught caused by the aspiration of saliva and tooth residues and treatment residues, since this in most cases results in unpleasant to severe pain on the teeth. The disadvantages in the use of the known oral irrigators are the constant spitting out of the liquid and the splashing in the front region of the mouth. The previous tongue cleaners are known as tongue scrapers or mechanical cleaners. Both devices have the following in common: a delivery channel (1) for a medium, and a removal channel (2) for media. In the saliva aspirator (B), warm air is delivered during the dental treatment and, at the same time, saliva, water and tooth residues are aspirated. In the cleaner (A) for the interdental spaces and tongue, a medium, e.g. water, is delivered and, after it strikes the tooth or tongue, is immediately aspirated again. Pleasant treatment and care of the teeth and effective tongue hygiene are thus possible.

Description

 Device for saliva suction, dental treatment, dental care and tongue cleaning.

It is known that in dental treatments mostly so-called saliva suckers are used so that there are no restrictions because of the accessibility to the teeth. Furthermore, it is known that so-called mouth rinse be used for cleaning the interdental spaces and also blasting agents for removing tartar and other coverings are used. In addition to oral hygiene, there are still so-called tongue scrapers and tongue brushes.

The disadvantages of the saliva ejector are the strong drafts, which is caused by the suction of saliva and tooth residues and treatment residues, because this usually causes unpleasant to severe pain on the teeth. The disadvantages of using the mouth rinser are the constant spitting out of the liquid as well as the spraying in the front area of the mouth and in the case of dental use of abrasives an additional saliva ejector must be used. Mouthwashers of this type also have the disadvantage that the water jet on the tooth enclosing gums and lifts and

Sinking food particles under the gum. With the tongue scraper or the tongue brush, the disadvantage is that the cleaning is not so effective because the unwanted residues and bacteria are only solved mechanically. The supply of warm air from

Hot air blower via the hose to the mouthpiece is problematic, since it cools very quickly in the hose even with the low consumption required. It must therefore take place a correspondingly high hot air flow rate in the hose, so that the required hot air flow with the appropriate temperature through the mouthpiece on the

Dental office arrives.

 The above-mentioned disadvantages can be solved by the present invention.

The present invention is based on the object to provide a device to allow the patient and home users a gentle, but effective and painless dental treatment, dental care and tongue care.

This is done on the one hand by gentle aspiration of the saliva with heated supplied air as a so-called saliva ejector and on the other hand in the tooth and tongue care by e.g. Liquid medium that runs through the inner feed channel and after exiting the channel acts briefly and then immediately from the outside

Outlet channel is sucked in by means of negative pressure and returned.

According to the invention the above object is achieved with the features of claim 1.

The invention is explained in more detail with reference to the drawing.

The apparatus shown in FIG. 1 comprises, as the most important components, a mouthpiece 1, a suction hose 2, a feed hose 3, a vacuum pump 4 and a heating element with blower or pump 5.

The illustration shown in FIG. 2 is used as a saliva ejector. The mouthpiece 1A has a port 1.3 for the suction hose 2 and a port 1.4 for the

Feed tube 3. Furthermore, it has an inner suction channel 1.1 and an outer feed channel 1.2. When used as a saliva ejector 5 warm air is passed through the feed channel 1.2 from the hot air blower and occurs at the oblique front of the

Mouthpiece out into the mouth. FIG. 4 shows how the air is distributed between the outer wall of the suction channel and the inner wall of the feed channel and flows forwards. The extraction of the mostly warm air together with the saliva takes place via a vacuum pump 4. We supply as much heated air as is sucked off. Thus, it is largely avoided that cold air flows from the external environment of the mouth opening into the oral cavity, past the sensitive

Teeth in the suction channel 1.1.

A saliva ejector mouthpiece 1B with three-sided air feed 1.2 and suction 1.1 can be seen in FIGS. 5 to 8. The flow arrows show the air movements. The illustrated, only three-sided feed channel serves to reduce the

External dimensions. Such nipple mouthpieces are used in children. In addition, the effect is achieved by the too close distance from hot air outlet to

Oral bottom of the saliva may be blown away. So that the hot air is better distributed in the oral cavity, outlet openings 1.5 are attached to the outer walls of the teat-mouthpiece IC. The air now flows straight to the front and on the other hand it flows through the outlet into the mouth. This can be seen in FIGS. 9, 10, 12 and in FIG. 13.

An additional novelty can be seen in FIGS. 9, 11, 12 and 13: In order that the tongue is not pulled against the suction channel 1.1 when the saliva is sucked off, a spacer 6 is inserted here. The spacer 6 has a relative distance to the oblique front of the mouthpiece, here indicated by the extension lines and the dimension arrows in Fig. 12. This distance ensures that the suction is not interrupted and enter the saliva together with solid waste material through the gap in the discharge channel can. The spacer 6 has on the back pin 1.7 with thicker heels for the distance to the teat mouthpiece IC and can be inserted into the holes 1.6.

Additional mounting options for this would still clip or postpone.

A further embodiment can be seen in FIGS. 14 to 18. Here it is

Mouthpiece 1D used for dental treatment and dental care. In this exemplary embodiment, the feed channel lies on the inside and the suction channel on the outside and surrounds the inner feed channel, ie exactly the opposite as in the previously described mouthpieces IA and IC. For example, To clean the interdental spaces, the mouthpiece with the lateral opening is applied to the teeth, so that the soft pad 1.8 made of foam, plastic or rubber rests all around the teeth and the gums. Now the water jet can be activated. The exiting water jet strikes the interdental space and the two teeth on the left and right of it and, together with food residues from the outer, the water jet surrounding air suction, returned to the discharge channel 1.1. Since the pad 1.8 rests against the gums and this presses against the tooth, no food particles can get between the tooth neck and the gums. Of course, the jet of water can also radiate to the entire tooth, so the mouthpiece can run off the entire row of teeth. The example mouthpiece 1D can also be used for dental treatment, e.g. for removal of dental plaque, bleaching or preventive measures.

Similarly, a tongue cleaning and care by moving the tongue surface is possible.

All channels can be switched in one direction only, both in the feed direction e.g. For increased warm air supply for tooth drying at the dentist or for 2-component treatment agent, as well as in the discharge direction for increased suction. Likewise, the individual channels can be switched on and off.

A further embodiment can be seen in FIG. 19 and FIG. 20: Here, a hose-in-hose system 10 can be seen, consisting of an outer hose 10A and an inner, loose hose 10B. Belonging are still supply hose 7, discharge hose 6 and merge part 9 with volume adjustment 9A and a mouthpiece 11. This hose in hose system has the advantage that the mouthpiece can be performed sensitively, as the inner, loose hose axially and radially within the interior of the outer tube can move freely. In addition, space is saved compared to a second outer tube or a twin tube. FIG. 21 shows the function of the hose-in-hose system: The hot air flow 12 comes via the hose 3 to the merge part 9 via the quantity adjustment 9A and extends between the outer hose 3 and the inner hose 2 forward to the mouthpiece 1 and its feed channel 1.2 and then comes forward from the mouthpiece 16 out.

The suction 13, generated by the vacuum pump 4, draws the warm ambient air 12 after leaving the mouthpiece 16 together with the saliva and the

Treatment residues in the discharge channel 1.1 and then in the inner tube 2 and from there into a collecting container. Figure 22 and Figure 23 show a merging part 14, e.g. from injection molding. It has exactly the same tube merging function as the merging part 9. In Figure 24 and Figure 25, the outer channel is in a straighter

Execution shown and the inner channel bent. In FIGS. 22 to 25, the inner channel penetrates at least one wall of the outer channel. FIG. 26 shows a

Hose- in hose version 17 with 2 connecting webs 17A for easier cleaning of the channel between large and small hose. FIG. 27 shows a mouthpiece 18 with a deflection channel 18.1. FIG. 28 shows the mouthpiece 18 shown in FIG. 27 in a central longitudinal section, with a feed channel 1.2, a suction channel 1.1 and an air reversal channel 18.1, and the feed port 18.2 and the concentric suction port 18.3.

FIG. 29 shows a mouthpiece 18 as a sectional view according to the sectional lines in FIG. 30. Here, in particular, the air reversing duct 18. 1 and the reversed hot air flow are shown

18.1.1 shown. Function: The hot air flow 1.2.1 generated by the fan heater 5 runs through the inlet channel 1.2 in the direction of the front outlet opening, wherein the feed channel 1.2 in the front region of the mouthpiece has a cross-sectional constriction, so that only the required part of the hot air emerges to the front, the rest of Hot air flow 18.1.1 but in the air reversing channel 1.8 is reversed and returned and as a cooling hot air flow

18.1.2 flows into the suction channel 1.1, where it is sucked by the vacuum pump 4. The advantage of this design is that the whole stream of hot air flows into the mouthpiece and heats it up quickly. FIG. 31 shows a central longitudinal section of the mouthpiece 18 with an air reversing duct 18.1 and the warm air flow 1.2.1, the air reversal flow 18.1.1 in the air reversing duct 18.1, and the suction duct 1.1 with exhaust flow 1.1.1.

FIG. 32 shows the cross-section of the mouthpiece 18 according to the section line in FIG. 31. Here one can see how the derived reverse hot air stream 18.1.1 flows around the suction channel 1.1 and then flows into the air reversal channel 18.1.

For heating the air flow, for example, a heating coil 19.1 can also be installed in the mouthpiece 19, as the example in FIG. 33 shows. The heating coil is fed by low current, which is guided along the supply hose. The cold air is passed over the feed channel 1.2 to the heating coil, heats up and then passes through the front mouthpiece opening in the treatment area. In place of the heating coil can also cartridge heaters or other heating elements are installed. To make mouthpieces 1 for the appropriate treatment quickly interchangeable is a so-called

Bayonet closure provided. It consists of the adapter piece 19, each with an O-ring 19.1 for the hot air supply and for the suction, seen in Figure 34. Figure 35 shows a mouthpiece 1 with locking pin 1.10. The mouthpiece 1 is guided with the locking pin 1.10 in the longitudinal grooves of the bayonet lock of the adapter piece and then pressed against the front side against the O-rings and then radially rotated, so that the locking pins are in the groove connected to the longitudinal groove and engage there. The connected state of mouthpiece with adapter 19 is shown in FIG. 36.
