Description

Background of the invention

[0001] The invention relates to a dermabrasion tool with a handpiece for manually holding and guiding the dermabrasion tool and a dermabrasion area at the axial end of the dermabrasion tool, wherein the dermabrasion area has a carrier matrix with a plurality of friction projections for mechanical skin treatment, which are arranged on the carrier matrix or formed in the carrier matrix, wherein the friction projections each have a maximum cross-sectional width between 0.5 µm and 1000 µm, wherein the handpiece has a cavity filled with a fluid, wherein the dermabrasion tool has an opening fluidically connected to the cavity.

[0002] Such a dermabrasion tool is known from EP 3 165 124 B1. The known dermabrasion tool has a dermabrasion area with a friction surface for roughening a skin area. The roughened skin area can be treated with the fluid.

[0003] The disadvantage of the well-known dermabrasion tool is its rather complex design and the associated high production costs for dosing the respective fluid. Object of the invention

[0004] It is therefore an object of the invention to provide a dermabrasion tool that can be manufactured significantly more cost-effectively without giving up the advantages of the known dermabrasion tool, and to simplify the targeted and standardized application of the dermabrasion area together with the fluid. Description of the invention

[0005] This object is achieved according to the invention by a dermabrasion tool according to patent claim 1. The dependent patent claims represent preferred developments.

[0006] The object of the invention is thus achieved by a dermabrasion tool as described above, wherein the handle is designed to be elastically and / or plastically deformable at least in sections, so that a user can press the fluid out of the opening in portions by pressing and / or rotating the handle. A user can simply press the fluid out of the opening by pressing and / or rotating the elastic and / or plastic section.

[0007] Preferably, the particles have a maximum cross-sectional width between 1 µm and 0.8 mm, in particular between 1 µm and 350 µm, preferably between 1 µm and 20 µm.

[0008] The application surface of the dermabrasion area is preferably round, oval or linear and has a diameter or maximum extension between 1 cm and 5 cm.

[0009] The fluid may contain an acid, an alkali, an emulsion / cream, and / or a medication. The fluid may contain a pathogen. In this case, penetration via micro-injuries can be used to easily achieve immunization and / or sensitization (in allergy sufferers) and / or administer therapeutic agents.

[0010] The elasticity and / or plasticity of the dermabrasion tool, at least in sections, can be brought about by a handle which has a film, in particular a plastic film.

[0011] The handle is preferably predominantly elastic, particularly preferably completely elastic. This allows the fluid to be pressed out of the dermabrasion tool particularly easily.

[0012] The dermabrasion tool can be designed particularly simply if the opening is located in the dermabrasion area. Preferably, the opening is completely radially surrounded by the dermabrasion area or is located adjacent to the opening.

[0013] In a particularly preferred embodiment of the invention, the handle is designed in the form of a tube or container. This significantly simplifies the manufacture and use of the dermabrasion tool.

[0014] The dermabrasion area can be arranged or formed on a separate component that is removable from the handpiece. The handpiece, including the fluid, can be replaced by removing the dermabrasion area or the component, so that the dermabrasion area can be applied to a new handpiece. The component can be attached to the handpiece or screwed on using a threaded connection.

[0015] The dermabrasion tool may have a lid to close the opening.

[0016] The aforementioned lid can be designed in the form of a screw cap with a lid thread. The handle can have an axial threaded projection with a handle thread matching the lid thread. More preferably, the threaded projection can have the opening.

[0017] In a further preferred embodiment of this embodiment, the thread projection can have the dermabrasion area.

[0018] The removable component may have the threaded projection.

[0019] The manufacture of the dermabrasion tool can be further simplified if the carrier matrix is in the form of a flat disc.

[0020] More preferably, the friction projections can be in the form of particles embedded in the carrier matrix. The carrier matrix can be made of glass, plastic, or paper. The particles can be fired into the carrier matrix or applied. The particles can preferably be in the form of sand grains, diamond dust, glass particles, metal particles, and / or plastic particles.

[0021] Further advantages of the invention will become apparent from the description and the drawings. Likewise, the above-mentioned and further-described features can be used individually or in combination in any desired manner. The embodiments shown and described are not intended to be exhaustive, but rather are exemplary in nature for describing the invention. Detailed description of the invention and drawing Fig. 1 shows an isometric view of a dermabrasion tool according to the invention.

[0022] Fig. 1 shows a dermabrasion tool 10 with a handpiece 12 and a dermabrasion area 14, wherein the dermabrasion area 14 has a carrier matrix 16 with several friction projections 18 for mechanical skin treatment.

[0023] The handle 12 is elastic and / or tube-shaped, so that by pressing, rotating and / or pushing the handle 12, a fluid 20 inside the handle 12 can be pressed out of the handle 12 through an opening 22.

[0024] The dermabrasion tool 10 has a cover 24 in the form of a screw cap with a cover thread 26. The cover thread 26 is configured in the form of an internal thread. The handle 12 has a threaded projection 28 with a handle thread 30. The handle thread 30 is configured in the form of an external thread.

[0025] The support matrix 16 is in the form of a flat disc, which is arranged or formed on the end face of the threaded projection 28. In this case, the support matrix 16 surrounds the opening 22.

[0026] In summary, considering the drawing, the invention relates to a dermabrasion tool 10 filled with fluid 20 and having an opening 22 for the discharge of the fluid 20. A handle 12 is preferably at least partially container-like or tube-like. A dermabrasion area 14 is preferably arranged or formed in the area of the opening 22, but can also be located at another location in the dermabrasion area 14.
