Description

The present invention relates to a device for cleaning strawberries and other tools in the field of odontology.

It is customary in dentistry practice to use strawberries to cut, use, polish, prepare, dig, cut ...

Depending on their purpose, these cutters can be made of timgthene carbide, covered with diamond particles, or silicone or rubber, or even Arkansas stone. Levus forms, sizes, surface states, structures are of great diversity.

All these strawberries are generally reusable and must after use follow the disinfection-sterilization cycle before being reused. Similarly, strawberries and disposable instruments in the context of strict asepsis can follow this same cycle.

Not only must the strawberries be disinfected and sterilized, but also cleaned and cleaned of dirt or debris that not only detracts from their appearance but is also effective.

But strawberries are usually small and often have particularly difficult to clean forms, with streaks, crevices, reliefs and recesses undercut.

However, it must be rid of dental debris, mucous, or metal fillings, or resins, or pasta, basically all types of materials that can be encountered in the dental world. The other difficulty comes from the diversity of textures, materials, and grains of strawberries. But all must be cleaned with the same efficiency. In addition to disinfection baths (various products exist on the market), it is customary to use ultrasonic trays that will rid strawberries of their biggest stains; then we use a small brush more or less wide, made of metal bristles, more or less long (plus the hairs are short plus their action is "hard", aggressive): it is called this carded instrument to strawberry.

However this exercise is long, tedious, and requires precision and total attention.

It is a question of taking the strawberries, one by one, at the end of the fingers (gloved), and to rub them with the card with strawberry in the direction of the streaks of the strawberry, in the crevices, to return there, sometimes to several times, until the result obtained is vahdé to the appearance.

This very long operation is tiring for the operator because the cutter is held securely at the end of the fingers, and the carding mill projects debris and dirt that can leave uncontrolled in the environment, or on the face, the eyes of the operator.

This metal brush may be suitable for certain types of strawberries, some metals, but for others softer, it can alter the surface condition, or worse, shape, geometry and thus alter the effectiveness.

But this manual operation, can be more harmful, because more insidious, potentially creating scratches, micro fissures or grooves that can be an environment favorable to the development of microorganisms or cellular debris, or DNA, with consequences uncontrollable in this world of care.

The device which is the subject of the application can remedy these drawbacks.

More specifically, the device according to the invention comprises a housing connected to a power source, an axis drivable in rotation with the aid of a control button, said axis comprising one or more brushes for cleaning strawberries. , an opening being provided in said housing for the introduction of the milling cutter.

According im preferred embodiment, said axis comprises several brushes of progressive hardness.

Advantageously, said device comprises means for varying the rotational speed of said axis. Other features of the device according to the present invention will appear better on reading the following description made with reference to the figures given for information only and in no way limiting, among which: - Figure 1 is a side view of the device according to the invention, and - Figure 2 is a front view of the device shown in Figure 1 and the associated cover. Referring now to Figure 1, it appears that the device according to the invention comprises a housing (1) provided with an opening (2) and is connected to a power source (3). This housing (1) can hold in one hand and be operated by simple pressure, eg thumb; it can also be placed on a support, stably, without being held and its shape must allow easy cleaning. The tool to be cleaned is referenced (F).

The device according to the invention also comprises an axis (4) on which are arranged coaxially several brushes (5) cylindrical; according to the variant embodiment illustrated, the axis (4) comprises a plmality of brushes (5). Without departing from the scope of the present invention, it would be conceivable to have a single brush (5); advantageously, however, several brushes (5) will be arranged on the axis (4) as shown in Figure 1. Even more advantageously, a hardness gradient will be provided, these brushes (5) having an increasing hardness, for example the harder at the base (6) of the axis (4) and the more flexible at the top (7) of the axis (4); the operator can for example distinguish different hardness, visually, by colors or by different diameters.

When the operator presses, or more generally actuates, the control button (8), the base of the latter will come to press the top (7) of the shaft (4) provided with its brushes (5); the axis (4) will then translate until its base (6) touches a contact, not shown here, in relation to the energy source (3), which will rotate said axis (4). ) and therefore the brushes (5) which are integral with said axis (4).

Preferably, the base (6) of the axis (4) has a square section which will fit into said contact also having a square shape; in this way, the rotation will be without skating at the axis (4). The axis (4) and its brushes (5) will constitute a removable assembly, and the operator will thus have a set of axis (4) / brushes (5), of different nature or not.

Each brush (5) will consist of a flat or thick cylinder whose periphery is covered with hair; these hairs, as already mentioned, may be of different hardness and / or different materials (eg nylon, metal, silk, etc ...). Preferably, the bristles of the brushes (5) will be oriented downwards to direct the debris towards the lower part of the device.

Alternatively, the bristles are no longer at the periphery of cylinders disposed on the axis (4), but are directly on the axis (4) in the manner of a swab. At the base (6) of the shaft (4) may be provided a concave portion (9) in the form of a hollow box, or bowl, removable or not, for collecting debris and residues from the cleaning of fiaises.

According to one embodiment of the invention, the opening (2) will be closed by means of a cover (10), preferentially transparent in whole or in part to facilitate visual and removable access so as to enable in particular change the axis sets (4) / brushes (5). Hinges (12) allowing the cover (10) to be positioned on the opening (2) closing the latter the time of use of the device according to the invention, means, not shown here, being provided at the level of the opening (2) for receiving said hinges (12).

This closure element is illustrated in Figure (2) from which it emerges that a window (11) has been made in said cover (10); possibly, several windows (11) can be made in said cover (10). The longitudinal axis of this or these windows, of oblong shape, will be provided to be substantially parallel to the axis (4).

This or these windows (11) can hold the cutters through the cover (10) and access the brushes (5) while protecting the projections of debris and dirt, and these windows (11) can guide strawberries in translation or in rotation; We thus have a fulcrum, a precious guide for cleaning.

In practice, the operator having actuated the control button (8), the axis (4) is rotating and the cutter meets the brushes (5); it suffices then to present said cutter at an angle, to turn it on itself between thumb and index finger, or even to translate it (if the cutter has a long working part) into the bristles of the brushes (5).

This use of the brushes (5) can be enhanced by the addition of a lubricant or disinfectant, or polishing or cleaning agents on the bristles of the brushes (5) before starting the device, or in the process of use for example through a window (11) of the cover (10), or directly through 1 'opening (2) in the absence of the cover (10). At the end of the use, the axis (4) of its brushes (5) is removed and cleaned by placing it in a disinfection tank before reuse.

A major advantage of the device according to the invention is that the axis sets (4) / brushes (5) are: - interchangeable - removable - cleanable (disinfection can be further provided) - adjustable; the brushes (5) may be identical, or with different bristles, allowing a gradient from top to bottom (or vice versa), ensuring intense cleaning until polishing in the same gesture, the diameters of the cylinders supporting said bristles may present or not the same diameter. - reusable.

Regarding the power source and the power system, the device according to the invention can be connected to mains, or thanks to a USB cord, or with interchangeable batteries, thus making the device transportable and not blocked in a place near a power outlet.

Advantageously, a variable speed drive will make it possible to adjust the speed of rotation of the shaft (4) driving its brush or brushes (5) according to the needs of the operator, depending on the type of operation to be performed and / or the type of tools to clean.

The present description is attached to a device for cleaning strawberries; it is understood that, without departing from the scope of the present invention, this device can also be used to clean tools other than strawberries, such as files, pins, drills, curettes or other small surgery parts in the field of odontology.
