Description

The technical field to which the invention relates

The present invention relates to an irrigation and suction system for oral care.

State of the art

Various oral care systems are currently known in the art.

So, from US patent No. 5104315 (publ. 04.14.1992) known device for oral hygiene, containing a tray with nozzles that can be connected to a source of cleaning solution, a source of foam, a vacuum pump.

In US patent No. 9504542 (publ. 11/29/2016) describes a device for cleaning teeth, in which a flexible one- or two-jaw mouthguard has elements for cyclic introduction and / or removal of fluid. During these cycles, the inside of the mouthguard rubs against the teeth.

In the patent of the Russian Federation No. 2630595 (publ. 09/11/2017) a device for the care of the oral cavity is disclosed, in which the two-jaw mouthguard contains in each part a plurality of collectors for supplying and (or) removing a hygienic liquid. Each manifold is connected to its own port for independent pressure or vacuum generation.

All of these and many other known devices are not suitable for use in a confined space, where it is difficult or impossible to provide fluid supply to and from the oral cavity without splashing or leaking from the oral cavity. The condition of the absence of leaks and even the provision of a closed cycle of fluid circulation in such a device is especially important when used in spacecraft for caring for the oral cavity of astronauts.

Disclosure of invention

The problem to be solved by the present invention is to create such a device for the care of the oral cavity, which would expand the arsenal of technical means while ensuring the tightness of use, especially in zero gravity.

To solve the specified problem and achieve the indicated technical result, the present invention proposes an irrigation-aspiration system comprising: a two-jaw mouthguard, made for a specific user, having cavities with dimensions for washing the teeth and adapted to adhere to the gums to prevent leaks, placed on the cavity wall opposite the interdental spaces of the nozzle connected to the tubes for supplying hygienic fluid from the inlet hose,

channels for collecting the waste hygienic liquid and draining it to the outlet hose;

a delivery pump for supplying said hygienic fluid through said inlet hose to a two-jaw mouthguard; a suction pump for withdrawing the waste hygienic liquid from the two-jaw mouthguard through the outlet hose, and a container for the hygienic liquid, connected to form a closed system to the pressure pump and through a filter for cleaning the waste hygienic liquid to the aspiration pump.

A feature of the system according to the present invention is that the double mouth guard can be made of silicone.

Detailed Description of Embodiments

The irrigation-aspiration system according to the present invention contains as the main element a two-jaw mouthguard (Fig. 1), which is pre-made for a specific user, the preferred material for such a two-jaw mouthguard is silicone, however, specialists understand that any other material acceptable for use with the user's oral cavity, both currently known and developed in the future. The advantage of silicone for the manufacture of a two-jaw guard is to ensure a tight seal when the guard is installed on the user's jaws.

FIG. 1, for greater clarity, a conditional model of a two-jaw mouthguard is shown placed in the model of the oral cavity, as if it was observed from behind, from inside the oral cavity. The double-jaw mouthguard 1 has cavities 2 and 3 for accommodating teeth, respectively, of the user's upper and lower jaws. FIG. 1, the teeth are schematically shown in dotted lines, with the teeth of the upper jaw indicated by the reference numeral 20 and the teeth of the lower jaw indicated by the reference numeral 30. The reference numeral 40 denotes the tongue outlined by the dotted line.

Cavities 2 and 3 have sufficient volume so that the hygienic liquid supplied through the mouthguard can wash the user's teeth and be collected for subsequent removal along with food debris washed out of the teeth. In this case, the edges of cavities 2 and 3 are made tightly adjacent to the corresponding gums to ensure that there is no leakage of the used hygienic liquid into the oral cavity. FIG. 1, nozzles 4 and 5 are visible in cavities 2 and 3, respectively, intended for supplying a hygienic liquid to the teeth of the corresponding jaw of the user.

FIG. 2 shows a schematic front view of a sweep of a two-jaw mouthguard 1 installed in the oral cavity. In this case, the front part of the two-jaw mouthguard 1, which encloses the user's teeth from the front, is shown transparent in order to better illustrate the implementation of the two-jaw mouthguard 1. Similar to the image in FIG. 1, FIG. 2, teeth are shown in dotted lines and have the same reference numerals 20 and 30. As seen in FIG. 2, nozzles 4 and 5 are located on the wall of the corresponding cavity 2 or 3 in places opposite the interdental spaces. This preferred arrangement of nozzles 4 and 5 is intended to better clean the user's teeth. However, it is clear to those skilled in the art that the specific placement of the nozzles 4 and 5 may be different, if this is required, say, by the technology for manufacturing a two-jaw mouthguard 1.

FIG. 2 shows tubes 6 and 7 for supplying a hygienic fluid from the inlet hose to the nozzles 4 and 5. The inlet hose 8 shown in FIG. 3, can be connected to a corresponding inlet (not shown) located on the two-jaw mouthguard 1, for example in its front part. FIG. 3 also shows a tube 9 serving to drain the waste hygienic liquid from cavities 2 and 3 through drains 19 to the outlet hose 10. It is clear to those skilled in the art that tubes 6 and 7 can be made in the body of the two-jaw mouthguard 1 or run separately from it in the corresponding cavities 2 and 3. In the first case, the nozzles 4 and 5 are made in the inner walls of the cavities 2 and 3, and in the second case, the nozzles 4 and 5 can be made in the form of holes directly in the tubes 6 and 7. FIG. 3 two-jaw mouth guard 1 is shown in section (oblique shading); wavy shading shows the sections of the upper jaw 21 and the lower jaw 31 with the teeth protruding from them, placed in cavities 2 and 3, respectively.

FIG. 4 is a schematic diagram of an irrigation-aspiration system according to the present invention. This system, in addition to the two-jaw mouthguard 1 with cavities 2 and 3, contains an injection pump 11 for supplying a hygienic liquid through the inlet hose 8 to the two-jaw mouthguard 1, a suction pump 12 for withdrawing the waste liquid from the two-jaw mouthguard 1 through the outlet hose 10, a storage tank 13 hygienic liquid connected to the pressure pump 11. Optionally, the irrigation-aspiration system may contain a filter 14 for cleaning the waste liquid. In this case, the irrigation-aspiration system can be made closed, which is conventionally shown in Fig. 4 by placing the filter 14 inside the container 13. Otherwise, the waste liquid can be removed from the system through the drain 15, shown in dotted lines.

The irrigation-aspiration system of the present invention operates as follows.

If it is necessary to process the oral cavity, the two-jaw mouthguard 1, pre-made for a specific user, is inserted into his oral cavity and fixed on both jaws. In this case, the user's teeth fall into the corresponding cavities 2 and 3. The injection pump 11 is turned on and supplies a hygienic liquid (for example, water) from the container 13 through the inlet hose 8 to the two-jaw mouthguard 1. The hygienic liquid entering the two-jaw mouthguard 1 passes through the tubes 6 and 7 (Fig. 2, 3) to nozzles 4 and 5 and, leaving them, washes the user's teeth and adjacent gums. Since the hygiene fluid is supplied under pressure, it flushes food debris from the interdental spaces and from the surface of the teeth. The spent liquid enters the cavities 2 and 3 and is removed from there through the drains 19 into the tube 9, and from it into the outlet hose 10 using the aspiration pump 12, which sucks the waste liquid from the two-jaw mouthguard 1.

In the simplest case, the removed waste liquid is discharged through drain 15 into a suitable tank. However, in a preferred embodiment, this waste liquid can pass through the filter 14 to remove food debris removed from the teeth. In this case, the irrigation-aspiration system can be made closed, when the purified liquid is returned to the reservoir 13 for reuse.

The irrigation-aspiration system of the present invention can find application, for example, for caring for immobilized patients who cannot brush their teeth on their own. Such a system will be especially suitable on spacecraft and stations, where, firstly, the conditions of zero gravity do not allow the proper use of conventional toothbrushes, and secondly, it is necessary to ensure the disposal of the waste liquid in order to avoid its loss and splashing.
