Description

Title of the invention: Phototherapy treatment device.

[0001] The present invention relates to a device for providing phototherapy or photomodulation treatment to improve skin health, such as anti-aging treatments or acne prevention, using light-emitting diode (LED) phototherapy, although other types of light radiation sources may be used.

[0002] Certain light spectra emitted by LEDs (blue or red) are known to be therapeutic for treating skin diseases such as acne or are beneficial for inhibiting skin aging. However, there is a need to provide users with a convenient home light therapy device, such as a mask, that is simple to use without discomfort to the user.

[0003] Currently available home products for consumer use on the market are fixed to a single size and / or generally have to be held in the hand, which has generally not proven satisfactory in ensuring the best diffusion of light. The alternative is for customers to go to a specialized institute to receive treatments.

[0004] Light therapy devices known in the prior art, particularly masks, have numerous problems related to the exposure of the LEDs and associated circuits for powering the LEDs to contact with users.

[0005] More particularly, in order to maximize light communication with the patient, the LEDs are generally arranged in a manner that allows the patient to be in physical contact with the LEDs, which causes the accumulation of dust and oil. In addition, such contact can be dangerous for patients who are exposed to the sharp or hot edges of the LEDs and associated circuitry. Exposure of detailed circuitry is an intimidating and unpleasant experience when the treatment takes several minutes and the mask is arranged relatively close to the face, often causing a feeling of claustrophobia and discomfort in the patient during the treatment period.

[0006] It has been observed in some users that certain areas of the face are likely to rapidly redden even after a medically approved exposure time. This results in particular in persistent redness in certain more sensitive parts of the face such as the eye area.

[0007] To remedy this, the user is forced either to limit the duration of exposure to the phototherapy treatment or to use phototherapy devices having a smaller emission surface which allows more targeted treatment of the face.

[0008] It will therefore be understood that there is a need for a facial mask which meets the need to effectively treat the entire face while limiting the risks of overexposure.

[0009] It will therefore be understood that there is a need for a facial mask which meets both the need to treat while limiting the risks linked to prolonged exposure of human facial tissue to this red light.

[0010] The invention aims in particular to provide a face mask making it possible to maximize the therapeutic effectiveness of the exposure while also limiting the risks of overexposure to red light.

[0011] For this purpose, the invention relates to a facial mask for phototherapy treatment of a user's face, comprising a frame delimiting a front face oriented towards a user's face and an opposite back face, the frame supporting a plurality of light-emitting light points arranged in the mask to produce energetic illumination of the user's face via the front face, characterized in that the facial mask defining, in facial correspondence, at least one remarkable line called a meridian from the forehead to the chin and a plurality of remarkable lines called parallel lines extending between each side of the face substantially transversely to the meridian line, the light points are arranged essentially along the parallel lines in order to produce a spatial distribution of the energetic illumination of the face having a maximum light power density along these lines.

[0012] Thanks to the mask of the invention, the distribution of the light sources or light points makes it possible to define target regions of high light power and target regions of lower light power along the line or from one line to another. This distribution makes it possible to guarantee optimal therapeutic effectiveness of the treatment of the human face.

[0013] A treatment device according to the invention may further comprise one or more of the following characteristics.

[0014] According to a preferred embodiment of the invention, the light power density generated by the light points varies along the same line and / or from one line to another.

[0015] According to a preferred embodiment of the invention, the maximum light power density (energy illumination also known in English as "irradiance") generated by the light points for a remarkable line has a value between 5 and 100 mW / cm2, in particular between 20 and 70 mW / cm2.

[0020] According to a preferred embodiment of the invention, each branch extends symmetrically with respect to a plane containing the meridian line.

[0022] According to a preferred embodiment of the invention, the main trunk comprises a connection terminal at one end of an electrical power supply cable for the light sources.

[0023] According to a preferred embodiment of the invention, the frame comprises two walls made of plastic material shaped to have a concavity oriented towards the face to be treated and between which extends the support carrying the light points.

[0024] According to a preferred embodiment of the invention, the frame comprises a heat dissipation plate shaped to fit the concavity of the body and arranged between the two walls, on which the support is mounted on the side of the plate facing the inner wall.

[0040] Figures 1 to 8 show a phototherapy treatment device according to a first embodiment of the invention. This device is designated by the general reference 100.

[0041] In the first embodiment, the device 100 comprises a face mask 10 and a support 200 for holding the treatment device 10 as will be detailed below.

[0042] As illustrated in detail in [Fig.l], the face mask 10 comprises a relatively rigid frame 12 of generally concave shape delimited by a peripheral edge 14, intended to be preferably positioned opposite an area to be treated of a user, here the user's face. In the example described, the frame 12 is formed from a rigid shell shaped to cover the entire face of the patient in a position of use.

[0043] Furthermore, the frame 12 further comprises a plurality of light-emitting light points 22, illustrated in detail in [Fig.5].

[0044] In this first embodiment, the light points 22 each comprise at least one light-emitting diode 24 with a red color spectrum in a wavelength mainly and preferably between 620 and 640 nm. Preferably, the luminous flux emitted by each light-emitting diode 24 is at least 30 lumens, for example in the range 30 lumens - 60 lumens.

[0045] In the example illustrated in [Fig.l], the frame 12 is shaped to cover the face by following the natural curvature of the face and thus has a concavity oriented towards the user's face. This concavity makes it possible to cover the face of a human being by following the natural curvature between the malar zones on the one hand and between the frontal zone and the lower maxillary zone on the other hand.

[0046] In this example, the concavity of the mask 10 makes it possible in particular to better fit and follow the contours of a user's face and thus make the exposure to the light radiation emitted by the light points 22 more effective.

[0047] Preferably, as illustrated in [Fig. 3], the frame 12 comprises a first inner front wall 30 intended to be positioned opposite the user's face. This inner wall 30 is preformed and has a generally concave shape, for example curvilinear to adapt to the physiognomy of a human face. Thus, preferably, as illustrated in [Fig. 3], the inner wall 30 has a general shape of a facial mask and comprises a central region having at least one curvature to follow the natural curvature of a human face.

[0048] The first inner wall 30 is made of a material that allows the light flux of the light-emitting diodes 24 to pass through. Preferably, the material is translucent to allow homogeneous diffusion of the light as well as natural protection of the user against glare. By translucent, we mean a material “that lets light pass through but is not transparent”. The choice of a translucent material rather than a transparent material also makes it possible, aesthetically, to make the light sources 24 less visible. Of course, as a variant, the material can be chosen to be transparent to the light rays emitted by the light sources 24.

[0049] Furthermore, preferably, the inner wall 30 is made of a thermoformable plastic material, for example a mixture of polystyrene and polyethylene (acronym PS-PE).

[0050] The inner wall 30 is thus preferably formed from a material capable of evolving depending on the temperature between a plastic phase and a rigid phase, by modeling said material in its plastic phase in a mold, then stiffening said material in place in the mold.

[0051] Furthermore, in accordance with the invention, the device 10 comprises a second wall 40 shaped to fit, in its final configuration, the first wall 30.

[0052] According to the invention, the light sources 22 are interposed between the two inner 30 and outer 40 walls.

[0053] The general manufacturing method of the frame 12 comprises, for example, the successive steps of (a) cutting a piece of said material, to the dimensions of the mold according to a shape extending in the mold, and (b) shaping said piece, by modeling the piece of material in its plastic phase, (c) stiffening the modeled material, in place in the mold to form the walls of the rigid shell (12), and (d) arranging recesses at eye level, either on the piece before it is shaped, or once the walls of the shell have been stiffened.

[0054] Preferably, the walls 30 and 40 are coupled together by fasteners, for example made of plastic material in the form of clips (not shown), and passing through coinciding orifices in the two walls 30 and 40. For this purpose, the internal wall 30 has a plurality of orifices and the external wall 40 comprises a plurality of corresponding fixing orifices.

[0055] Furthermore, as illustrated in [Fig. 3], in the first embodiment of the invention, the mask 10 comprises a support 20 for electrically connecting the light sources 24 to an electrical power source. In this first embodiment, the support 20 has a general shape of an openwork plate sufficiently deformable to match the concavity of the mask 10.

[0056] According to the invention, for the facial mask 10, at least one remarkable line called the meridian M1 from the forehead to the chin and at least one remarkable line called the predefined parallel P extending between each side of the face are considered in facial correspondence.

[0057] In the remainder of the description, we will consider a decomposition of a human face according to predefined parallel lines P which are noteworthy for the treatment of wrinkles extending transversely to a main meridian line Ml which extends from the forehead to the upper maxillary region, as is schematically illustrated by [Fig.2]:

[0058] - a first frontal parallel line PI remarkable for example for the treatment forehead wrinkles;

[0059] - a second main parallel malar line P2 extending from one side of the face to the other for the treatment, for example, of nasolabial fold wrinkles,

[0060] - a third parallel maxillary line P3 extending at the level of the user's mouth for the treatment, for example, of perioral wrinkles.

[0061] According to the invention, the light points 22 are arranged mainly along these parallel lines (possibly optionally along the main meridian line) in order to produce a spatial distribution of the energy illumination of the face having a maximum luminous surface power density in regions located along these lines and a minimum at a distance from these lines. By "mainly" it will be understood that preferably more than three quarters (or even more than 90%) of the light points 22 are arranged along the parallel lines.

[0062] More particularly, in this first embodiment, the support 20 delimits at least one main trunk 52 extending substantially along the meridian line M1 and a plurality of branches 54 extending substantially along at least two distinct parallel lines P1 to P3.

[0063] In the illustrated example, the support 20 delimits a main meridian trunk 52 and a frontal branch 54.1 and a lower maxillary branch 54.3. The support 20 further comprises two lateral meridian branches 52.1 and 52.2 extending substantially parallel to the main meridian trunk 52 allowing it to extend laterally along the contour of the face. The support 20 preferably also comprises a malar branch 54.2.

[0064] In order to provide increased flexibility to the support 20, this malar branch 54.2 is connected in a secondary manner to the main meridian trunk 52 via, for example, the lateral meridian branches 52.1 and 52.2. The branches 54 of the support 20 form, in the illustrated example, a double “E” arrangement arranged opposite each other in a symmetrical manner relative to the meridian trunk 52 to which they are connected.

[0065] Preferably, the support 20 comprises a plurality of so-called “primary” branches 54.1 and 54.3 because they are directly connected to the trunk 52 and at least one so-called “secondary” branch 54.2 connected indirectly to the trunk 52 via at least one primary branch 54.1 or 54.3.

[0066] The parallel line is for example chosen from a lower orbital line, an upper orbital line, a lower maxillary line, a frontal line, an upper maxillary line, a central malar line. Particular parallel lines include in particular a frontal line, a lower maxillary line, an upper maxillary line, a central malar line and a lower orbital line and an upper orbital line.

[0067] The decomposition of the mask into high energy dosage lines makes it possible to optimize the energy supply of light in very specific and targeted areas of the user's face and to limit the energy supply of light in areas requiring little or no phototherapy treatment.

[0068] Furthermore, preferably, the light energy dosage rate (otherwise considered the surface density of light power) varies along the same line and / or from one line to another, which also makes it possible to treat certain localized areas (for example the periorbital region) with an adjustment of the light energy dosage rate.

[0069] For example, the variation of the surface density of luminous power is obtained by varying the linear density of the luminous points along a line and / or from one line to another.

[0070] In this example, the maximum light power density, or illumination, generated by the light points 22 for a remarkable line has a value between 5 and 100 mW / cm2, in particular between 20 and 70 mW / cm2.

[0071] For example, the irradiance in a periorbital region is preferably close to 25 mW / cm2 (with a margin of 20%). In a malar and maxillary region of the face, this irradiance is preferably higher, for example closer to 70 mW / cm2 (with a margin of 20%). In a frontal region of the face, this irradiance is preferably median, for example close to 40 mW / cm2 (with a margin of 20%).

[0072] Preferably, the light power density emitted on each meridian or parallel line by the light points 22 varies along a branch 54, or from one branch 54 to another, or from a branch 54 relative to the trunk 52.

[0073] For example, the distance separating two light sources 22 along a branch 54 is variable to vary the power density. Preferably, each branch 54 extends symmetrically with respect to a plane containing the meridian line M1.

[0074] According to the invention, the light sources 22 are interposed between the two inner walls 30 and outer walls 40. Furthermore, preferably, the heat dissipation plate 60 extends between the outer wall 40 and the support 20.

[0075] In the variant illustrated in [Fig.8], the support 20 still comprises a main meridian trunk 52 and a plurality of parallel branches 54 starting from this trunk 52.

[0076] In this variant, the parallel branches 54 have curvilinear shapes to follow the natural curvature of the face as closely as possible. In this variant, the support 20 always delimits a frontal parallel branch 54.1, a parallel malar branch 54.3.

[0077] Generally speaking, the remarkable parallel lines P of the human face include in particular a frontal line, a lower maxillary line, an upper maxillary line, a central malar line and periorbital lines (lower orbital line and an upper orbital line). It can be seen in [Fig.2] that these lines (represented in a continuous line) are curvilinear in a main transverse direction.

[0078] Thus, preferably, in this variant, the support 20 additionally delimits lower 54.4 and upper 54.5 periorbital parallel branches as well as an upper maxillary branch 54.6. Furthermore, the support 20 also comprises a secondary semi-circumferential branch 56 indirectly connected to the meridian trunk by the branch 54.3, extending substantially along a circumferential line defined by a general semi-oval shape of a lower part of the face.

[0079] Preferably, in this variant, the support 20 comprises at least one deformable segment 58 providing flexion and longitudinal extension of the support 20 located on the segment 58. The conformation into an elastically deformable segment 58 provides additional flexion and longitudinal extension of the support 20.

[0080] As illustrated in [Fig.8], the deformable segment 58 has a general S shape or a general sinusoidal wave shape. Generally, the segment 58 may have a general wavy shape.

[0081] Furthermore, the support 20 also comprises a secondary semi-circumferential branch 56 indirectly connected to the meridian trunk by the branch 54.3, extending substantially along a circumferential line defined by a general semi-oval shape of a lower part of the face.

[0082] In [Fig. 1], the support 200 comprises a base 210 and a self-supporting flexible tube 220 allowing the orientation of the mask 10 to be modified ergonomically as well. Preferably, the flexible tube 220 is configured in a “swan neck” shape so as to support the face mask 10 while also allowing the orientation of the device 10 to be modified.

[0083] A flexible tube called a "swan neck" or in English "stand tube" can deform along a curvilinear trajectory while ensuring a support function. In a manner known per se, such a tube is produced for example from a combination of two generally metallic windings of round and triangular sections which wind alternately longitudinally.

[0084] Preferably, the support 200 comprises a plastic sheath which covers the flexible tube 220 over its entire length in order to allow the flexible tube 220 to be handled under optimal hygienic conditions.

[0085] The base 210 forms in this example a housing enclosing an electronic control card (not shown) for the light sources 22 according to a predefined processing protocol. In addition, the support 200 comprises a power cable intended to be connected at one of its ends to an electrical power source, for example the general power supply of a domestic electrical network and at the other of its ends to the electrical connection support of the light sources 22. Preferably, the housing also comprises, for example, a conventional AC / DC converter. This electrical power cable extends inside the flexible tube.

[0086] For this purpose, preferably, the support 20 comprises a terminal block 50 for connection to one end of the electrical power supply cable. In the example illustrated, the terminal block 50 extends over the meridian trunk 52, preferably in the vicinity of a free end of this trunk 52. Preferably, the electrical connection terminal block 50 comprises a cable gland type arrangement 70 at the end of the cable to ensure sealing and mechanical stability of the light source circuit 22 with respect to the external environment. In a manner known per se, a cable gland type arrangement 70 comprises a compressible packing, at the origin of the cable which is compressed using a nut or an annular screw 72. Such a cable gland 70 makes it possible to maintain and ensure sealing around the electrical cable.

[0087] Furthermore, as illustrated in [Fig.7], the face mask 10 further comprises a heat dissipation interface 60 made for example of aluminum. This dissipation interface 60 is in the form of a curvilinear plate comprising an opening 64 for the passage of the power cable and recesses 68 for the user's eyes. The opening 64 also comprises on a peripheral edge a tab 66 pierced for the passage of the electrical power cable and the cable gland arrangement 70. Preferably, each branch 54 extends symmetrically with respect to a plane containing the meridian line M1.

[0088] Preferably, each branch 54 extends symmetrically with respect to a plane containing the meridian line M1.

[0089] Figures 9 and 10 show the face mask 10 according to a second embodiment of the invention. In this second embodiment, elements similar to those of the first embodiment bear identical references.

[0090] In the second embodiment, the frame 12 is textile and comprises a plurality of optical fibers 80 in warp and / or weft woven with threads for binding the fibers of the frame 12, each optical fiber 80 comprising a longitudinal body provided along its longitudinal direction with invasive alterations 82 open on the front face of the frame 12 and at least one free end opposite which is arranged a light emission source 86 for transmitting and emitting light at the alterations 82 of the front face to form the plurality of light points.

[0091] Preferably, the linear density and / or the dimension of the alterations 82 varies along each optical fiber 80 to produce variable surface illumination from a front face of the frame 12.

[0092] For example, the frame 12 is made of canvas and / or satin and in which the binding threads are formed from a material chosen from the group comprising polyamide, polyester, polyethylene and polypropylene.

[0093] The main aspects of the operation and manufacture of a treatment apparatus and treatment device according to the invention will now be described.

[0094] With reference to [Fig.l], when switching on the device 100, the user positions the mask 10 in front of his face so that his eyes coincide with the recesses 16 of the mask 10. The treatment protocol can then start.

[0095] With reference to [Fig.9], the user installs the mask 10 by means of the Velcro fasteners 84 around his head. The treatment protocol can also be launched.

[0096] Of course, the invention is not limited to the embodiments previously described. Other embodiments within the reach of those skilled in the art may also be envisaged without departing from the scope of the invention defined by the claims below.
