DEVICE FOR PHOTOGRAPHIC TREATMENT

Description

[0001] The present invention relates to a device for providing phototherapy or photomodulation treatment to improve skin health, such as anti-aging treatment or acne prevention treatment, 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 effective in treating skin conditions such as acne or in inhibiting skin aging.

[0003] It is therefore desirable to provide users with a practical home phototherapy device, such as a mask, that is easy to use and does not cause discomfort. Such a mask is notably described in document US2018 / 0352936.

[0004] The products currently available for home use by consumers on the market are fixed at a single size and / or generally require hand-holding, which has generally not proven satisfactory for ensuring optimal light diffusion. The alternative is for clients to visit a specialized institute for treatments.

[0005] Phototherapy devices known in the prior art, particularly masks, present numerous problems related to the exposure of LEDs and associated circuits to power the LEDs to contact with users.

[0006] Specifically, in order to maximize the amount of light reaching the user's face, LEDs are generally arranged in such a way as to allow the user to come into physical contact with them, which causes dust and oil to accumulate near or on the LEDs. Furthermore, such contact can be hazardous to users who are exposed to the sharp or hot edges of the LEDs and their associated circuitry.

[0007] Direct exposure to circuits and LEDs can also be an intimidating and unpleasant experience when the treatment lasts several minutes and the mask is positioned relatively close to the face, often causing a feeling of claustrophobia and discomfort for the user during the treatment period.

[0008] It has been observed in some users that certain areas of the face are prone to rapid reddening, even during medically approved exposure times. This results in persistent redness, particularly in more sensitive areas of the face such as around the eyes.

[0009] To remedy this, the user is forced either to limit the duration of exposure to phototherapy treatment or to use phototherapy devices with a smaller emission surface that allows for more targeted and localized treatment of the face.

[0010] Therefore, there is a need for a face mask that meets the need to effectively treat the entire face while limiting the risks of overexposure to red light.

[0011] To this end, 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 emission points arranged in the mask to produce energetic illumination of the user's face by the front face, characterized in that the facial mask defines, in facial correspondence, at least one notable line called the meridian from the forehead to the chin and a plurality of notable lines called parallels extending between each side of the face substantially transverse to the meridian line,The light points are arranged essentially along parallel lines in order to produce a spatial distribution of the facial energy illumination exhibiting maximum light power density along these lines, and in that the light power density generated by the light points varies from one line to another or along the same line in order to define target regions of high light power and target regions of lower light power along the line or from one line to another, wherein the varying light energy dosage rate along the same line and / or from one line to another allows the light energy dosage rate to be adjusted in a lower orbital line and a higher orbital line defining a periorbital region such that the energy illumination in the periorbital region is lower than in a malar or maxillary region of the face.

[0012] Thanks to the mask of the invention, the distribution of light sources or light points makes it possible to define target regions of high light intensity and target regions of lower light intensity along the line or from one line to another. This distribution ensures optimal therapeutic efficacy for treating the human face.

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

[0014] According to a preferred embodiment of the invention, the light points have a spatial distribution observable from the front face of the mask defining a network pattern of distinct lines that are discernible from one another.

[0015] According to a preferred embodiment of the invention, the face can be decomposed into a plurality of zones that may be marked by wrinkles, the network defines a plurality of lines of luminous points arranged to cross said zones, the length of each line of the network being dimensioned according to a transverse extent of the area crossed by the line.

[0016] According to a preferred embodiment of the invention, the network includes at least one curvilinear line, for example to follow a periorbital or perioral contour of the face.

[0017] According to a preferred embodiment of the invention, the luminous power density generated by the luminous points varies along the same line and / or from one line to another.

[0018] According to a preferred embodiment of the invention, the maximum luminous power density (energy illumination also known in Anglo-Saxon terminology as "irradiance") generated by the luminous points for a notable line has a value between 5 and 100 mW / cm², in particular between 20 and 70 mW / cm².

[0019] According to a preferred embodiment of the invention, the linear density of the light points varies along a line and / or from one line to another.

[0020] According to a preferred embodiment of the invention, defining a circumferential line which follows a general peripheral oval shape of the face along which a plurality of luminous points are arranged.

[0022] According to a preferred embodiment of the invention, each light point being formed by a light-emitting diode, the armature includes a support for electrically connecting the light-emitting diodes to each other, said support comprising at least one main trunk extending substantially along the meridian line and at least two branches extending substantially along at least two distinct parallel lines.

[0023] According to a preferred embodiment of the invention, each branch extends symmetrically with respect to a plane containing the meridian line.

[0024] According to a preferred embodiment of the invention, comprising a plurality of primary branches connected directly to the trunk and at least one secondary branch connected indirectly to the trunk via at least one primary branch.

[0025] According to a preferred embodiment of the invention, the main trunk includes a terminal block for connection at one end of a power supply cable for the light sources.

[0026] According to a preferred embodiment of the invention, the frame comprises two walls of plastic material shaped to present a concavity oriented towards the face to be treated and between which extends the support carrying the light points.

[0027] According to a preferred embodiment of the invention, the frame includes a heat dissipation plate shaped to fit the concavity of the body and disposed between the two walls, on which is mounted the support on the side of the plate facing the inner wall.

[0028] According to a preferred embodiment of the invention, the frame is textile and comprises a plurality of warp and / or weft optical fibers woven with binding threads of the frame fibers, each optical fiber comprising a longitudinal body provided along its longitudinal direction with invasive alterations open on the front face of the frame and at least one free end opposite which is arranged a light emission source to transmit and emit light at the level of the alterations of the front face to form the plurality of light points.

[0029] According to a preferred embodiment of the invention, the linear density and / or the dimension of the alterations varies along the optical fiber or from one optical fiber to another.

[0030] According to a preferred embodiment of the invention, the frame is made of canvas and / or satin and in which the binding threads are formed from a material chosen from the group including polyamide, polyester, polyethylene and polypropylene.

[0033] We have represented on the figures 1 à 10 A phototherapy treatment device according to a first embodiment of the invention. This device is designated by general reference 100.

[0034] In the first embodiment, the device 100 includes a face mask 10 and a support 200 for holding the treatment device 10 as will be detailed below.

[0035] As illustrated in detail on the figure 1 The face mask 10 comprises a relatively rigid frame 12, generally concave in shape and delimited by a peripheral edge 14, intended to be positioned preferably opposite a treatment area of ​​a user, in this case the user's face. In the example described, the frame 12 is formed of a rigid shell shaped to cover the entire face of the patient in a usage position.

[0036] In addition, the frame 12 further comprises a plurality of luminous points 22 for light emission, illustrated in detail on the figure 5 .

[0037] 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 primarily 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 within the range of 30 lumens to 60 lumens.

[0038] In the example shown on the figure 1 The frame 12 is shaped to cover the face by conforming to its natural curvature, and thus presents a concavity oriented towards the user's face. This concavity allows it to cover the human face by following the natural curve between the malar areas on one hand, and between the frontal area and the lower jaw on the other.

[0039] In this example, the concavity of the mask 10 allows it to better fit and follow the contours of a user's face and thus make exposure to the light emitted by the light points 22 more efficient.

[0040] Preferably, as illustrated on the figure 3 The frame 12 includes a first inner front wall 30 intended to be positioned opposite the user's face. This inner wall 30 is pre-formed and has a generally concave shape, for example curvilinear, to adapt to the physiognomy of a human face. Thus, preferably, as illustrated in figure 3 , the inner wall 30 has a general face mask shape and includes a central region having at least one curvature to follow the natural curvature of a human face.

[0041] The first inner wall 30 is made of a material that allows the light from the light-emitting diodes 24 to pass through. Preferably, the material is translucent to allow for homogeneous diffusion of light and natural protection of the user against glare. Translucent means a material that allows light to pass through but is not transparent. Choosing a translucent material rather than a transparent one also makes the light sources 24 less visible from an aesthetic point of view. Of course, as an alternative, the material can be chosen to be transparent to the light rays emitted by the light sources 24.

[0042] In addition, preferably the inner wall 30 is made of a thermoformable plastic material, for example a mixture of polystyrene and polyethylene (acronym PS-PE).

[0043] The inner wall 30 is thus preferably formed from a material capable of evolving according to temperature between a plastic phase and a rigid phase, by shaping said material in its plastic phase in a mold, then stiffening said material in place in the mold.

[0044] Furthermore, according to the invention, the device 10 includes a second wall 40 shaped to fit, in its final configuration, the first wall 30.

[0045] According to the invention, the light sources 22 are intercalated between the two inner wall 30 and outer wall 40.

[0046] The general manufacturing process of the frame 12 includes, for example, the successive steps of (a) cutting a piece of said material to the dimensions of the mold according to a shape spreading in the mold, and (b) shaping said piece by molding the piece of material in its plastic phase, (c) stiffening the molded material in place in the mold to form the walls of the rigid shell (12), and (d) making recesses at the eye level, either on the piece before it is shaped, or once the walls of the shell have been stiffened.

[0047] Preferably, the walls 30 and 40 are coupled together by fasteners, for example made of plastic in the form of clips (not shown), and passing through coincident orifices in the two walls 30 and 40. For this purpose, the inner wall 30 has a plurality of orifices and the outer wall 40 includes a plurality of corresponding fixing orifices.

[0048] Furthermore, as illustrated on the figure 3 In the first embodiment of the invention, the mask 10 includes a support 20 for electrically connecting the light sources 24 to a power supply. In this first embodiment, the support 20 has a general shape of a perforated plate sufficiently deformable to conform to the concavity of the mask 10.

[0049] According to the invention, for the face mask 10, in facial correspondence, at least one notable line called meridian M1 from the forehead to the chin and at least one notable line called predefined parallel P extending between each side of the face are considered.

[0050] In the following description, we will consider a decomposition of a human face along predefined parallel lines P, notable for the treatment of wrinkles extending transversely to a principal meridian line M1 that extends from the forehead to the upper jaw, as schematically illustrated by the figure 2 : a first parallel frontal line P1 notable for example for the treatment of forehead wrinkles; 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, a third parallel maxillary line P3 extending to the level of the user's mouth for the treatment for example of perioral wrinkles.

[0051] According to the invention, the luminous points 22 are arranged primarily along these parallel lines (optionally along the principal meridian line) in order to produce a spatial distribution of facial illumination with maximum surface power density in areas located along these lines and minimum density at a distance from these lines. "Primarily" is understood to mean that preferably more than three-quarters (or more than 90%) of the luminous points 22 are arranged along the parallel lines.

[0052] The parallel line is chosen, for example, from a lower orbital line, a superior orbital line, a lower maxillary line, a frontal line, a superior maxillary line, or a central malar line. Specific parallel lines include, among others, a frontal line, a lower maxillary line, a superior maxillary line, a central malar line, and both a lower and a superior orbital line.

[0053] Preferably, the luminous points 22 exhibit a spatial distribution observable from the front of the mask 10, defining a network pattern of distinct and distinguishable lines. This network distribution is not uniform across the face and instead takes the form of network lines that cross target areas of the user's face.

[0054] In the example described, the face can be broken down into a plurality of areas that may be marked by wrinkles; the network defines a plurality of lines of light points arranged to cross said areas, the length of each line of the network being dimensioned according to a transverse extent of the area crossed by the line.

[0055] For example, the area likely to be marked by wrinkles is chosen from a malar area including cheek wrinkles and nasolabial and melolabial folds, a frontal area including forehead wrinkles and frown lines, a periorbital area including periorbital wrinkles and / or a perioral area including wrinkles around the mouth.

[0056] For example, the network pattern includes at least one curvilinear line, for example to follow a periorbital or perioral contour of the face.

[0057] 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.

[0058] In the illustrated example, support 20 delineates a main meridian trunk 52 and a frontal branch 54.1 and a lower maxillary branch 54.3. Support 20 also includes 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. Support 20 preferably also includes a malar branch 54.2.

[0059] As illustrated on the figure 5 In order to provide increased flexibility to support 20, this malar branch 54.2 is secondarily connected to the main meridian trunk 52 via, for example, the lateral meridian branches 52.1 and 52.2. The branches 54 of support 20 form in the illustrated example a double “E” arrangement arranged opposite each other symmetrically with respect to the meridian trunk 52 to which they are connected.

[0060] Preferably, the support 20 comprises a plurality of branches called "primary" 54.1 and 54.3 because they are directly connected to the trunk 52 and at least one branch called "secondary" 54.2 indirectly connected to the trunk 52 via at least one primary branch 54.1 or 54.3

[0061] The decomposition of the mask into high energy dosing 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 that do not require or require little phototherapy treatment.

[0062] In addition, preferably, the light energy dosing rate (otherwise considered the surface density of light power) varies along the same line and / or from one line to another, which also allows certain localized areas (for example the periorbital region) to be treated with an adjustment of the light energy dosing rate.

[0063] For example, the variation in surface density of light power is obtained by varying the linear density of light points along a line and / or from one line to another.

[0064] In this example, the maximum luminous power density, or energy illumination, generated by the light points 22 for a notable line has a value between 5 and 100 mW / cm 2<, in particular between 20 and 70 mW / cm 2<.

[0065] For example, the energy irradiance in a periorbital region is preferably close to 25 mW / cm² (with a margin of error of 20%). In the malar and maxillary regions of the face, this energy irradiance is preferably higher, for example, closer to 70 mW / cm² (with a margin of error of 20%). In the frontal region of the face, this energy irradiance is preferably mid-range, for example, close to 40 mW / cm² (with a margin of error of 20%).

[0066] Preferably, the luminous power density emitted on each meridian line or parallel by the luminous points 22 varies along a branch 54, or from one branch 54 to another, or from one branch 54 to the trunk 52.

[0067] 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.

[0068] According to the invention, the light sources 22 are interposed between the two inner wall 30 and outer wall 40. Furthermore, preferably, the heat dissipation plate 60 extends between the outer wall 40 and the support 20.

[0069] In the first variant illustrated on the figure 8 , support 20 always includes a main meridian trunk 52 and a plurality of parallel branches 54 starting from this trunk 52.

[0070] In this variant, the parallel branches 54 have curvilinear shapes to closely follow the natural curvature of the face. In this variant, the support 20 always delimits a frontal parallel branch 54.1 and a malar parallel branch 54.3.

[0071] In general, the notable parallel lines P of the human face include, in particular, a frontal line, a lower jawline, an upper jawline, a central malar line, and periorbital lines (lower orbital line and upper orbital line). We observe on the figure 2 that these lines (represented as continuous lines) are curvilinear along a principal transverse direction.

[0072] Thus, preferably, in this variant, support 20 further delimits parallel inferior periorbital branches 54.4 and superior periorbital branches 54.5 as well as an upper maxillary branch 54.6. Moreover, support 20 also includes a secondary semi-circumferential branch 56 indirectly connected to the meridian trunk by branch 54.3, extending substantially along a circumferential line defined by a general semi-oval shape of a lower part of the face.

[0073] Preferably, in this variant, the support 20 comprises at least one deformable segment 58 providing a longitudinal bending and extension of the support 20 localized on the segment 58. The conformation in elastically deformable segment 58 provides additional longitudinal bending and extension of the support 20.

[0074] In the first variant, as illustrated on the figure 8 The deformable segment 58 can have a general S-shape or a general sinusoidal wave shape. Generally, segment 58 can exhibit a wavy shape.

[0075] Furthermore, support 20 still includes a secondary semi-circumferential branch 56 indirectly connected to the meridian trunk by branch 54.3, extending substantially along a circumferential line defined by a general semi-oval shape of a lower part of the face.

[0076] In the second variant illustrated on the figures 9 And 10 , the secondary semi-circumferential branch 56 is interrupted in order to provide improved flexibility of support 20.

[0077] Furthermore, as is very clearly apparent on the figure 10 The lines of luminous dots 22 form a spatial distribution in the form of a network pattern, visible from the front face of the mask 10. This network pattern allows for the best possible tracking of the facial epidermis mapping by parallel lines that cross areas likely to be marked by wrinkles.

[0078] On the figure 1 The support 200 includes a base 210 and a self-supporting flexible tube 220 that also allows for ergonomic adjustment of the mask 10's orientation. Preferably, the flexible tube 220 is configured in a "gooseneck" shape to support the face mask 10 while also allowing for adjustment of the device 10's orientation.

[0079] A flexible tube, known as a "gooseneck" or "stand tube," can deform along a curved path while providing support. Typically, such a tube is made, for example, from a combination of two coils, usually metallic, with round and triangular cross-sections, which are wound alternately longitudinally.

[0080] Preferably, the 200 support includes a plastic sleeve that covers the 220 flexible tube along its entire length to allow the 220 flexible tube to be handled under optimal hygienic conditions.

[0081] In this example, the base 210 forms a housing enclosing an electronic control board (not shown) for the light sources 22, which are controlled according to a predefined processing protocol. Furthermore, the support 200 includes a power cable intended to be connected at one end to a power source, for example, the main power supply of a domestic electrical network, and at the other end to the electrical connection support for the light sources 22. Preferably, the housing also includes, for example, a conventional AC / DC converter. This power cable extends inside the flexible tube.

[0082] For this purpose, preferably, the support 20 includes a terminal block 50 for connection at one end of the power supply cable. In the illustrated example, the terminal block 50 extends along the meridian section 52, preferably near a free end of this section 52. Preferably, the electrical connection terminal block 50 includes a cable gland arrangement 70 at the end of the cable to ensure the sealing and mechanical stability of the light source circuit 22 against the external environment. As is known per se, a cable gland arrangement 70 includes a compressible packing, at the origin of the cable gland, which is compressed by means of a nut or ring screw 72. Such a cable gland 70 makes it possible to maintain and ensure the sealing around the power cable.

[0083] Furthermore, as illustrated on the figure 7 The face mask 10 further includes a heat dissipation interface 60 made, for example, of aluminum. This heat dissipation interface 60 is in the form of a curved plate comprising an opening 64 for the passage of the power cable and recesses 68 for the user's eyes. The opening 64 also includes, on a peripheral edge, a tab 66 drilled for the passage of the power cable and the cable gland assembly 70. Preferably, each arm 54 extends symmetrically with respect to a plane containing the meridian line M1.

[0084] Preferably, each branch 54 extends symmetrically with respect to a plane containing the meridian line M1.

[0085] We have represented on the figures 10 And 11the face mask 10 according to a second embodiment of the invention. In this second embodiment, the elements analogous to those of the first embodiment bear identical reference numerals.

[0086] In the second embodiment, the frame 12 is textile and comprises a plurality of optical fibers 80 in warp and / or weft woven with binding threads of 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 to transmit and emit light at the level of the alterations 82 of the front face to form the plurality of light points.

[0087] Preferably, the linear density and / or dimension of the alterations 82 varies along each optical fiber 80 to produce variable surface illumination from a front face of the frame 12.

[0088] 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 including polyamide, polyester, polyethylene and polypropylene.

[0089] We will now describe the main aspects of the operation and manufacture of a treatment apparatus and treatment device according to the invention.

[0090] With reference to the figure 1 When the device 100 is switched on, the user positions the mask 10 in front of their face so that their eyes coincide with the cutouts 16 in the mask 10. The treatment protocol can then start.

[0091] With reference to the figure 11The user installs the mask 10 using the Velcro fasteners 84 around their head. The treatment protocol can then be initiated.

[0092] Of course, the invention is not limited to the embodiments described above. Other embodiments within the grasp of a person skilled in the art may also be considered without departing from the scope of the invention as defined by the following claims.
