Description

[0001] This application is a divisional application based on the patent application with international application number PCT / GB2021 / 052683, international application date October 15, 2021, priority date October 15, 2020, Chinese national phase application number 202190000914.1, and invention name “Skin Disease Treatment Device”. Technical Field

[0002] The present disclosure relates to dermatological treatment devices, dermatological treatment device assemblies, dermatological treatment methods, dermatological treatment device manufacturing methods, and kits of parts. In particular, but not exclusively, the present disclosure relates to light-based, self-contained adhesive dermatological treatment devices. Background Art

[0003] Treatment of dermatological conditions, such as acne and rosacea, may be considered in one of two ways—either through the skin care route using over-the-counter active ingredients in the form of creams or lotions or impregnated hydrocolloid dressings, or through the skin technology route, such as phototherapy, electromechanical abrasion devices, or ultrasound or electrical stimulation devices.

[0004] Skin care products are typically applied quickly and do not require specialized knowledge, but require a sustained and consistent approach to treatment. Active ingredients typically require at least two or three skin growth cycles (56 to 84 days) to show any noticeable effect, and users often stop treating with a particular skin care product long before it has had enough time to provide noticeable effects on the underlying skin. However, when used correctly, skin care products can provide significant improvements to dermatological conditions.

[0005] The problem with using skin care products to treat dermatological conditions, such as acne and rosacea, is that creams and lotions can alter the properties of the skin's defense barrier (skin covering) and / or the skin's biome, and this can lead to inflammation and slow the healing process of the dermatological condition. This is especially true in situations where users apply multiple skin care products during their daily lives.

[0006] Recent advances in skin care have seen the use of hydrocolloid dressings for the treatment of dermatological problems. These hydrocolloid dressings contain medication to further aid the treatment process which relies on the absorptive properties of the dressing or uses micro-spikes to increase the efficiency of active absorption. These hydrocolloid dressings offer the advantage of masking the area undergoing treatment and prevent the user from poking or otherwise interfering with the skin condition which could otherwise slow the healing process.

[0007] Skin technologies typically use electronic or electromechanical devices that require application for longer periods of time than skincare products and occasionally require some expertise to ensure that the area is neither under- nor over-treated. For example, phototherapy requires that an adequate dose of light be applied to the area; under-treatment may result in insufficient destruction of bacteria, and over-treatment may result in increased inflammation of the skin. Initial results are usually seen quickly, for example blue light phototherapy can significantly reduce the number of bacteria on the skin within a week of use, however only continued use will achieve long-term results. For example, in blue light phototherapy, the reduction in bacteria is only temporary, and once treatment is stopped, the bacteria level returns to normal.

[0008] The inventors have identified a need for the long-term benefits of skin care use and the ease of use with the immediate results of skin technology.

[0009] The present disclosure seeks to solve or alleviate at least some of the above mentioned problems.Alternatively or additionally, it is an object of the present disclosure to provide a device and method for the treatment of dermatological conditions which provides both immediate and lasting results.

[0010] Alternatively or additionally, the present disclosure seeks to provide an improved dermatological treatment device. Alternatively or additionally, the present disclosure seeks to provide an improved dermatological treatment device assembly. Alternatively or additionally, the present disclosure seeks to provide an improved method of treating a dermatological condition. Alternatively or additionally, the present disclosure seeks to provide an improved method of manufacturing a dermatological treatment device. Utility Model Content

[0011] According to a first aspect of the present disclosure, there is provided a skin disease treatment device, comprising:

[0012] a light emitting component for emitting light for treating skin diseases;

[0013] Wherein, the skin disease treatment device also includes a skin treatment dressing,

[0014] Skin therapeutic dressings are bioactive dressings;

[0015] The skin treatment dressing is arranged to adhere to the skin of a user during use;

[0016] the skin treatment dressing being arranged with the light emitting member such that, in use, light from the light emitting member is transmitted to the skin treatment dressing; and

[0017] Therein, the skin treatment dressing is configured so that light from the light emitting component passes through the skin treatment dressing to reach the user's skin.

[0018] The bioactive skin treatment dressing can shield the area undergoing treatment, thereby preventing the user from poking or otherwise interfering with the skin condition, which could otherwise slow the healing process, while allowing light from the light emitting component to pass through the bioactive skin treatment dressing to provide dermatological treatment. Thus, the dermatological treatment device can provide the advantages of both a skin treatment dressing and phototherapy. In this regard, the dermatological treatment device can provide the long-term benefits and ease of use of a skin treatment dressing with the immediate results of phototherapy.

[0019] In this regard, applying both light and a bioactive dressing for dermatological treatment to the skin provides a synergistic technical effect for many different phototherapy treatments using different colors / wavelengths of light.

[0020] In one example, Propionibacterium acnes (p.acne) is a Gram-positive microaerophilic bacterium and plays a major role in acne vulgaris by causing an inflammatory response in the skin. p.acne releases porphyrins, which are a group of organic compounds naturally present in the body and produced during the synthesis of heme in red blood cells. Porphyrins are pigment compounds, and when porphyrins absorb blue light (wavelength of 407nm-420nm), porphyrins produce free radicals. The important feature of free radicals is that free radicals have extremely high chemical reactivity and can cause damage to nearby cells. When free radicals are produced in (or around) p.acne bacteria, the reactivity destroys the p.acne bacteria. However, acne vulgaris is formed by a complex chain of biological events, and simply removing p.acne bacteria is not enough to prevent the recurrence of acne. Although blue light can reduce the level of bacteria in inflamed pores, the environment that causes bacteria is still the same, and unless the environment changes, p.acne will develop rapidly again.

[0021] Bioactive dressings (e.g., hydrocolloid dressings) modify the pore environment and provide topical keratolytics to break down and help remove skin cells and skin oils from clogged pores - this then allows air to return to the pores and create a hostile oxygen-rich environment for p.acne. By combining blue light with topical keratolytics from a bioactive dressing, a synergistic effect can be achieved in reducing symptoms of acne vulgaris because this allows for lower keratolytic concentrations with continuous treatment (in short, reducing inflammation by removing bacteria allows keratolytics to work more effectively within the pores, and vice versa, by reducing the density of pore blockages, coupled with the antimicrobial effects of some keratolytics like salicylic acid, allows for a reduction in the number of bacteria present in the pores, which in turn promotes a greater overall reduction from the blue light).

[0022] As another example, red light (wavelength of 585nm to 830nm, preferably 633nm) stimulates the production of collagen, elastin and fibroblasts. Irradiation with 633-nm light increases the synthesis of type 1 procollagen, reduces the expression of matrix metalloproteinases (MMP) 1 and MMP2 in skin fibroblasts, and reduces the expression level of interleukin-1-α (1L-1α) and inflammatory genes such as cyclooxygenase-2 (COX-2) in keratinocytes). The production of collagen is very complicated and requires complex fuels of vitamin C, peptides and monosaccharides. Most importantly, vitamin C is an essential auxiliary factor for two enzymes required for collagen synthesis: prolyl hydroxylase (to stabilize collagen molecules) and lysyl hydroxylase (to give structural strength cross-linking). It has been found that when administered orally, the bioavailability of vitamin C in the skin is insufficient. Topically applied vitamin C (e.g., in face creams) has low bioavailability due to rapid oxidation processes.

[0023] However, bioactive dressings such as hydrocolloid dressings allow for gradual release of active agents such as vitamin C to overcome the low bioavailability of vitamin C. For example, by providing vitamin C in a hydrocolloid and applying red light, a synergistic effect was created where the synthesis of type 1 procollagen was increased more than with topical vitamin C or red light alone.

[0024] Bioactive dressings are dressings that deliver substances active in wound healing by delivering one or more bioactive compounds, or are dressings constructed from materials with intrinsic activity. These materials include hydrocolloids, alginates, collagen, chitosan, chitin, derivatives of chitosan or chitin, and biotextiles. In embodiments of the present disclosure, the bioactive dressing includes one or more active agents.

[0025] Optionally, the skin therapeutic dressing is a hydrocolloid dressing.

[0031] Optionally, the outer surface of the skin treatment dressing is provided with a removable layer. This can protect the skin treatment dressing before it is applied to the user's skin and keep the skin treatment dressing sterile.

[0032] In an embodiment of the present disclosure, a skin treatment dressing is attached to the light emitting component.

In this case, the skin treatment dressing may be releasably attached to the light emitting component due to the adhesive component / properties of the skin treatment dressing. Furthermore, due to the adhesive component / properties of the skin treatment dressing, the skin treatment dressing may adhere to the user's skin during use.

[0036] Alternatively or additionally, an adhesive may be provided on the upper surface of the skin treatment dressing. In this case, the skin treatment dressing may be releasably attached to the light emitting component by the adhesive.

In this aspect, the switch device can be configured to detect when the skin treatment dressing is in contact with the user's skin. Since the switch device automatically turns on the light-emitting component when the presence of the skin is detected, the switch device can provide ease of use.

[0038] Optionally, the switch means comprises a first electrode and a second electrode, the first electrode and the second electrode being adapted to switch on the light emitting component when the presence of the skin is detected by a change in an electrical signal between the two electrodes.

[0039] Optionally, the dermatological treatment device comprises a timer adapted to control the duration for which the light emitting member is switched on to deliver a predetermined dose of light to the user's skin.

[0040] Optionally, the timer is adapted to be activated when the dermatological treatment device is placed on the user's skin. In this aspect, the timer can be configured to be activated when the dermatological treatment dressing is placed on the user's skin.

[0041] Optionally, the dermatological treatment device comprises a rechargeable battery system configured to power the light emitting component.

[0042] Optionally, the rechargeable battery system includes a rechargeable battery and an inductive coupling configured such that the rechargeable battery can be charged by the charger unit through electromagnetic induction.

[0043] Optionally, the rechargeable battery system includes a rechargeable battery configured to be charged by the charging attachment when the charging attachment is attached to the dermatological treatment device.

[0044] According to a second aspect of the present disclosure, a dermatology treatment device assembly is provided, which includes a dermatology treatment device according to the first aspect of the present disclosure, wherein the rechargeable battery system includes a rechargeable battery and an inductive coupling, the inductive coupling is configured so that the rechargeable battery can be charged by a charger unit through electromagnetic induction, wherein the dermatology treatment device assembly also includes a charger unit.

[0045] According to a third aspect of the present disclosure, a dermatology treatment device assembly is provided, which includes a dermatology treatment device according to the first aspect of the present disclosure, wherein the rechargeable battery system includes a rechargeable battery, and the rechargeable battery is configured to be charged by a charging attachment device when attached to the dermatology treatment device, wherein the dermatology treatment device assembly also includes a charging attachment device.

[0046] Optionally, the charging attachment is a charging base.

[0047] The skin treatment dressing may be in a shape that is advantageous to the area of ​​the user to be treated. For example, the skin treatment dressing may be in a teardrop shape under the eye, a crescent shape on the lip, a circular shape for acne. The skin treatment dressing may be shaped in a manner that allows multiple skin treatment dressings to be positioned adjacent to each other, such as in a hexagonal shape.

[0048] Although specific output specifications for light pulses emitted from the light emitting components of the preferred embodiment will be explained in more detail below, an exemplary device according to the preferred embodiment may generate light pulses according to the following parameters:

[0049] 80mW output power

[0050] Spot size 12cm (patch is teardrop shaped)

[0051] Constant wave (non-pulse)

[0052] Wavelength: 633nm

[0053] An exemplary device according to a preferred embodiment can generate light pulses according to the following parameters:

[0054] Output power: 2.181mW (equivalent to 30J / cm in 3 hours)

[0055] Spot size (or output aperture area): 0.5 cm 2

[0056] Pulse width: 0.500s

[0057] Pulse repetition frequency: 0.5Hz

[0058] Wavelength: 410nm

[0059] In an embodiment, the light emitting component is configured to output an energy density of 0.01 J / cm 2 and 50J / cm 2 The light source may be pulsed, and in a preferred embodiment, the light source is pulsed at a repetition rate of up to 0.5 Hz.

[0060] In a preferred embodiment, the light emitting component outputs 404 nm light with a wavelength of 30 J / cm 2 This wavelength is absorbed by the c.acne bacteria that cause acne, and the absorption by the c.acne bacteria causes the acne bacteria to self-destruct. In a preferred embodiment, the time used is 3 hours.

[0061] In a second preferred embodiment, the light emitting component outputs light in the red to near infrared spectral range (between 600nm-1100nm) with a power of 9J / cm 2 -30 J / cm 2 Energy density in the range of , output power range of 10 mW-200 mW, preferably 80 mW per LED, with approximately 8 LEDs.

[0062] These parameters stimulate the production of collagen, elastin and fibroblasts to heal wounds within the user's skin.In a preferred embodiment, the duration of use is 3 hours.

[0063] In a third preferred embodiment, the light emitting component emits light in multiple bands, such as both blue 400nm light and red 600nm light. Since the action spectrum for tissue regeneration and repair consists of more than one wavelength, it is advantageous to apply a multicolor spectrum covering a wider spectral region for skin rejuvenation and skin repair.

[0064] In a fourth preferred embodiment, the light emitting component emits light of multiple wavelength bands, for example, both red 633 nm light and infrared 1072 nm light.

[0065] Optionally, the skin treatment dressing comprises at least one light transmission region configured to provide a stronger transmission of light from the light emitting component to the user's skin than other regions of the skin treatment dressing.

[0066] The problem with using skin treatment dressings such as hydrocolloids is that the material has a certain degree of light absorption, and this reduces the efficiency of light therapy. In testing, the inventors found that this absorption depends on the nature of the material, the wavelength of the transmitted light (light absorption is proportional to frequency) and the thickness of the skin treatment dressing (light absorption is proportional to thickness).

[0067] For a given material, the obvious solution to this problem is to increase the light output of the light emitting component to compensate for the losses or to reduce the thickness of the light transmissive layer. However, both of these solutions offer additional difficulties.

[0068] Increasing the light output requires a greater amount of power and therefore increases the size of the power supply, or, if the power supply is not increased, reduces the maximum medical treatment time. The dermatological treatment device needs to be attached to the skin, and therefore a larger size power supply (larger sized power supplies are generally larger and heavier) makes any attachment difficult to achieve and uncomfortable for the user (the weight of the power supply is borne by the skin). Reducing the maximum medical treatment time is also unacceptable - a certain light dose is usually required to treat skin conditions with phototherapy. The inventors found in testing that for commonly available batteries, increasing the light output to the level required to treat skin conditions results in a medical treatment time that is less than the medical treatment time required to provide the medical dose. In addition, the inventors found that increasing the light output also results in a proportional increase in heat in the skin treatment dressing. This causes the skin treatment dressing to become too soft, thereby losing the adhesive properties of the skin treatment dressing and being unable to be attached to the skin.

[0069] Likewise, it was found that reducing the thickness of the skin therapeutic dressing resulted in a material that was too thin to provide adequate support to allow the skin therapeutic dressing and light emitting component to remain attached to the skin.

[0070] The at least one light transmission region allows for greater transmission of light from the light emitting component through the skin treatment dressing to the user's skin, thereby increasing the efficiency of the light therapy.

[0071] Furthermore, these advantages can be provided while allowing the skin treatment dressing to still provide sufficient support to allow the skin treatment dressing and the light emitting component to remain attached to the skin. In this regard, the at least one light transmission area avoids having to provide increased power and therefore avoids having to use a larger power source, thereby making it easier to attach to the user's skin and making it more comfortable for the user to wear. Likewise, this can provide the required medical time without having to increase the power of the power source. Likewise, since no increased power is required, this avoids an increase in heat in the skin treatment dressing. Therefore, this avoids the skin treatment dressing from becoming too soft, so that the skin treatment dressing does not lose its adhesive properties and thus does not fail to attach to the user's skin.

[0072] The light emitted from the light emitting component can have one or more wavelengths between 300nm and 1600nm, preferably, the light should have a wavelength between 400nm and 1100nm, and even more preferably, at two or more wavelength peaks between 400nm and 420nm, 630nm and 690nm, and 1010nm and 1080nm, respectively. The light emitting component (e.g., a light emitting source, see below) can output each of these wavelength peaks instantaneously, or can output each of a sequence of one or more wavelengths, which can be achieved under the control of a control module (see below). For example, the light emitting component (e.g., under the control of a control module) can emit a first light of 400nm-420nm for a first predetermined duration, followed by a second light of 630nm-690nm and 101nm-1080nm for a second predetermined duration. Such a sequence can be beneficial to certain physiological skin disorders, such as acne vulgaris and psoriasis, where the sequential nature of the treatment provides improved treatment of the disorder compared to non-sequential treatment. This is particularly evident where the use of 400nm-420nm light requires a generally shorter duration than the use of 630nm-690nm light, and where overexposure to 400nm-420nm light can lead to complications in treatment, such as pigmentation. The light may be emitted continuously or pulsed, for example under the control of a control module (see below).

[0073] The light emitted from the light emitting component may be red light. The red light may have a wavelength of 585 nm to 830 nm, preferably 633 nm.

[0074] The light emitted from the light emitting component may be blue light. The blue light may have a wavelength of 407nm-420nm).

Optionally, the skin disease treatment device comprises a control module configured to control the power supply from the power source to the light source.

The control module may also include a communication component for wireless communication with a third device, such as a Bluetooth or infrared connection with a smartphone, to allow remote control of the dermatological treatment device. The dermatological treatment device may be configured so that the user can directly control the dermatological treatment device through a downloaded smartphone application or through a wireless connection with a remote computer.

[0079] Optionally, the light emitting component comprises a rigid or semi-rigid housing. The light source may be provided in the housing.

Alternatively or additionally, the skin treatment dressing may be coupled to the light emitting component by mechanical or magnetic coupling.

[0082] Optionally, the flexible skin treatment dressing is a hydrocolloid. However, other materials such as hydrogels may be used.

[0149] refer to Figure 1 , shows a skin care device in the form of a dermatological treatment device 1, which includes a light-emitting component 2 and a skin treatment dressing 3, which is releasably attached to the light-emitting component 2.

[0150] The light emitting component 2 includes a self-contained housing 4 configured to be adhered to the user's skin 5 for a dermatological treatment procedure. A light source 6 is mounted in the housing 4, and the light source 6 may include one or more light emitting diodes and / or diode lasers. The light emitting diode may be an inorganic or organic LED, such as a quantum dot LED. The light source 6 and associated electronic circuitry are contained within the housing 4. The electronic circuitry includes one or more power supplies 7, which are used to excite the light source 6 to generate output light pulses sufficient to provide effective dermatological treatment.

[0151] In the embodiment described above, the power source 7 is a 3.7V, 24mAh printed lithium battery. Such a battery can power multiple LEDs and has an ultra-thin profile that allows the housing to have a lower profile (the taller the device, the more the device pivots on the skin, which can be uncomfortable for the user as the device pulls on the skin).

[0152] For example, the power source 7 can be one or more small battery cells, each rated at 1.2V, and providing a voltage between 1.0V and 1.5V during the course of a discharge cycle. A typical LED uses about 20mA, and a CR2032 coin cell has a capacity of 200mAh. This allows a skincare device using a single LED light source to be used for 10 hours, or 3 applications of the skincare device before replacement.

[0153] The housing 4 further comprises a first region 8 for releasably attaching the skin therapy dressing 3 .

[0154] The light path (L) within the housing includes an aperture 9 within the first region 8 through which the output light propagates out of the housing 4 and through the skin therapy dressing 3 .

[0155] In this aspect, the skin treatment dressing 3 is made of a material that allows light from the light emitting component 2 to pass through the material to the user's skin 5. The skin treatment dressing 3 is transparent or translucent.

[0156] The skin treatment dressing 3 is a bioactive dressing. In the presently described embodiment, the skin treatment dressing is a hydrocolloid dressing. Hydrocolloids are heterogeneous groups of long chain polymers (polysaccharides and proteins) characterized by the property of forming a viscous dispersion and / or gel when the hydrocolloid is dispersed in water. Hydrocolloids are transparent or translucent.

[0157] The skin treatment dressing 3 is used to be applied to the user's skin to cover the treated area of ​​the skin. In addition, the skin treatment dressing 3 includes one or more active agents. In an exemplary embodiment, the active agent is salicylic acid, benzoyl peroxide, retinoids, fruit acids, polyhydroxy acids, hyaluronic acid or sulfur, retinol or retinol esters, peptides, sodium hyaluronate, niacinamide, caffeine, camellia sinensis extract (green tea), azelaic acid or ascorbic acid. Examples of peptide compounds can be Matrixyl 3000 and / or Eyeliss, both of which are trademarked peptide components developed by Sederma Co., Ltd.

[0158] In an exemplary embodiment, the active ingredients are niacinamide, caffeine, Eyeliss, Matrixyl 3000, sodium hyaluronate, and sodium hydroxide.

[0159] In another exemplary embodiment, the active ingredients are sodium hyaluronate, camellia sinensis extract (green tea), salicylic acid, niacinamide, oligopeptide-76, and sodium hydroxide.

[0160] In another exemplary embodiment, the active ingredients are azelaic acid, ascorbic acid, oligopeptide-34, sodium hyaluronate, sodium hydroxide.

[0161] Skin treatment dressings can be any type of bioactive dressing. Bioactive dressings are dressings that deliver substances active in wound healing by delivering bioactive compounds or are constructed from materials with endogenous activity. These materials include hydrocolloids, alginates, collagen, chitosan, chitin, derivatives of chitosan or chitin, and biotextiles.

[0162] The skin treatment dressing 3 includes one or more active agents selected from the group consisting of salicylic acid, benzoyl peroxide and sulfur associated with hydrocolloid dressings, wherein the active agent is present in an amount that does not reduce the absorption capacity of the hydrocolloid dressing.

[0163] In an exemplary embodiment, the active agent is present in an amount of about 0.01% to about 10%, for example, the active agent is salicylic acid present in an amount of about 0.1% to about 2% or about 0.5% to about 1.2%. In additional embodiments, the active agent is benzoyl peroxide present in an amount of about 2.5% to about 10%, or in another embodiment, the active agent is sulfur present in an amount of about 3% to about 10%.

[0164] Also provided herein is a therapeutic device for acne consisting essentially of a hydrocolloid dressing and salicylic acid is present in an amount of about 0.5% to about 1.5%.

[0165] In another embodiment, the hydrocolloid dressing is in the form of an application pad having a size of about 0.5 cm to about 4 cm.

[0166] Skin treatment dressing 3 is a sheet dressing.

[0167] The skin treatment dressing 3 is configured to support the light emitting component 2 on the skin of a user.

[0168] The skin treatment dressing 3 is releasably attached to the light emitting component 2. This allows the skin treatment dressing 3 to be replaced after each use. In the currently described embodiment, the skin treatment dressing 3 has a back side 42, which is provided with an adhesive layer 43 so that the skin treatment dressing 3 is releasably adhered to the lower surface of the housing 4. However, it will be appreciated that any suitable form of releasable attachment means may be used, for example, a physical connector such as a hook and loop or a magnetic connection. Alternatively or additionally, the skin treatment dressing 3 may be made of an adhesive material so that the skin treatment dressing 3 itself is releasably adhered to the lower surface of the housing 4.

[0169] The skin treatment dressing 3 has a skin contacting front side 40 which is provided with an adhesive layer 41 for adhering to the user's skin in use. In the presently described embodiment, the adhesive is glue. In the presently described embodiment, the adhesive is a standard tissue adhesive. It should be understood that any suitable adhesive may be used, including, for example, polyethylene film or silicone adhesive.

[0170] Alternatively or additionally, the skin treatment dressing may be made of an adhesive material so that the skin treatment dressing itself adheres to the user's skin during use. This advantageously allows the dermatological treatment device 1 to adhere to the user's skin during use, thereby helping to keep the device in place on the area of ​​skin to be treated.

[0171] The skin contacting front side 40 is provided with a removable layer 30. This protects the skin therapy dressing 3 and keeps the skin therapy dressing 3 sterile, and also protects the adhesive 41 before the skin therapy dressing 3 is applied to the skin of a user.

[0172] In use, the skin treatment dressing 3 is configured so that light from the light emitting component 2 passes through the skin treatment dressing 3 to the user's skin. In this aspect, the skin treatment dressing 3 is made of a material that allows light emitted from the light emitting component 2 to pass through.

[0173] In the described embodiment, the light emitting component emits light pulses according to the following parameter contents:

[0174] Output power: 2.181mW (equivalent to 30J / cm in 3 hours)

[0175] Spot size (or output aperture area): 0.5 cm 2

[0176] Pulse width: 0.500s

[0177] Pulse repetition frequency: 0.5Hz

[0178] Wavelength: 410nm

[0179] In an alternative embodiment (ie, for each of the described embodiments), the light source outputs light at a wavelength of 404 nm with a power of 30 J / cm 2 This wavelength is absorbed by the P. acnes bacteria c. acne, which causes the acne bacteria to self-destruct. In a preferred embodiment, there is light therapy for 10 minutes and the hydrocolloid dressing remains in place for 3 hours.

[0180] In another alternative embodiment (i.e., for each of the embodiments described above), the light source outputs light with a wavelength in the red to near infrared spectral range (between 600nm-1100nm) having a power of 9J / cm 2 Up to 20J / cm 2 The energy density is preferably 17 J / cm 2 These parameters are known to stimulate the production of collagen, elastin and fibroblasts to heal wounds within the user's skin. In a preferred embodiment, there is light therapy for 10 minutes and the hydrocolloid dressing remains in place for 3 hours.

[0181] In yet another alternative embodiment (i.e., for each of the embodiments described above), the light source outputs multiple bands of light, such as both blue 400nm light and red 600nm light, or both 633nm and 1072nm light. Because the action spectrum for tissue regeneration and repair consists of more than one wavelength, it is advantageous to apply a polychromatic spectrum covering a wider spectral region for skin rejuvenation and skin repair.

[0182] The skin treatment dressing 3 shields the area undergoing treatment, thereby preventing the user from poking or otherwise interfering with the skin condition, which may otherwise slow the healing process, while allowing light from the light emitting member 2 to pass through the skin treatment dressing 3 to provide dermatological treatment. Thus, the device 1 provides the advantages of both a skin treatment dressing and phototherapy. In this regard, the device 1 provides the long-term benefits and ease of use of a skin treatment dressing with the immediate results of phototherapy.

[0183] refer to Figure 2 , shows a dermatological treatment device 101 according to a second embodiment of the present disclosure. Except for the differences described below, the dermatological treatment device 101 of the second embodiment is the same as the dermatological treatment device of the first embodiment. Corresponding features are given corresponding reference numerals, but increased by 100.

[0184] In the second embodiment, the dermatological treatment device 101 further comprises a switch device 111 for activating the light source 106. In a preferred embodiment, the switch device 111 is configured to detect the presence of the skin 5 using an electrical signal between the two electrodes 112A, 112B, the switch device 111 is located on either side of the first area 108, and is adapted to activate the circuit when the presence of the skin 5 is detected by a change in the electrical signal. Other switch devices may be used without departing from the scope of the present disclosure, including mechanical switches, timer switches, and wireless switches, or a combination thereof.

[0185] The treatment device 101 also includes a timer 110, which is suitable for delivering a predetermined dose of light to the user's skin 5 and is also suitable for activating when the skin care device is placed on the user's skin. In this aspect, the timer 110 and the switch device 111 are electrically configured to be activated simultaneously when the skin contacts.

[0186] refer to Figure 3 , shows a dermatological treatment device 201 according to a third embodiment of the present disclosure. Except for the differences described below, the dermatological treatment device 201 of the third embodiment is the same as the dermatological treatment device of the first embodiment. Corresponding features are given corresponding reference numerals, but increased by 200. Figure 4 The electronic circuit 250 of the dermatological treatment device 201 of the third embodiment is shown.

[0187] The skin disease treatment device 201 of the third embodiment includes a mechanical switch 220 that is pushed when the treatment device 201 is placed on the skin of a user.

[0188] This turns on switch 220 (see Figure 4 ), so that the power supply 207 supplies power to the light source 206.

[0189] refer to Figure 5 , shows the electronic circuit of a skin disease treatment device 301 according to a fourth embodiment of the present disclosure. Except for the differences described below, the skin disease treatment device 301 of the fourth embodiment is the same as the skin disease treatment device of the third embodiment. Corresponding features are given corresponding reference numerals, but increased by 100.

[0190] In the dermatological treatment device 301 of the fourth embodiment, the electronic circuit 350 further includes a rechargeable battery system 351, wherein the dermatological treatment device regulates the transfer of energy from a separate charger unit 352. For recharging, the charger unit 352 is brought close to the device 301. An oscillating current is generated in a primary coil 353 located in the charger unit 352. By inductive coupling of an oscillating magnetic field, an alternating current is generated in a secondary coil 354 within the electronic circuit 350. The alternating current then passes through a half-wave or full-wave rectifier 355 to form a single-sided current, and then passes through a regulator (not shown) to form a direct current, which in turn is directed to the rechargeable battery 307 in the electronic circuit.

[0191] In a preferred embodiment, between uses of the skin care device, the device is preferably placed in a charging base 360. The charging base 360 ​​can be similar to those currently produced for use with electric toothbrushes, shavers, cell phones, etc. The base 360 ​​is connected to a standard AC outlet and is capable of charging the battery overnight. In another preferred embodiment, the charging base includes a housing with a shallow tray that is positioned above the primary coil, which is electrically connected to the charging circuit and the mains supply. In use, one or more skin care devices are positioned in the shallow tray for charging.

[0192] refer to Figure 6 and Figure 7 , shows a skin disease treatment device 401 according to a fifth embodiment of the present disclosure. Except for the differences described below, the skin disease treatment device 401 of the fifth embodiment is the same as the skin disease treatment device of the first embodiment. Corresponding features are given corresponding reference numerals, but increased by 400.

[0193] Device 401 includes a light emitting component 402 and a skin treatment dressing 403 .

[0194] The lighting component 402 includes a rigid or semi-rigid housing 404. The light source 406 is attached to the outer surface of the housing 404. The power supply 407 and the control module 480 are housed in the housing 404. The control module 480 is electrically interconnected with the light source 406 and the power supply 407, and is adapted to control the power supply from the power supply 407 to the light source 406.

[0195] The control module 480 includes hardware, such as a microcontroller, for controlling the light source of the light emitting component. The control module 480 includes a user interaction component to allow the user to control the output of the light source. The device is configured so that the user can control the output based on the desired results for a specific skin condition, and can select a "therapy mode" with a predetermined light output characteristic, and the control module will control the light source for this purpose. Alternatively, the device can be configured so that the user can directly select the light output and control which output parameters (e.g., wavelength, duration, intensity) are selected. The control module may also include a communication component for wireless communication with a third device, such as a Bluetooth or infrared connection with a smartphone, to allow remote control of the device. The device can be configured so that the user can directly control the device through a downloaded smartphone application or through a wireless connection with a remote computer.

[0196] The power supply 407 comprises a battery and battery control hardware (not shown). The battery may be recharged via a second power source, such as mains power, and the power supply may also comprise charging hardware adapted to allow charging of the power supply. The charging hardware may comprise an electrical charging socket, or may allow wireless charging by using an inductive charging device. Such charging devices are well known in the art.

[0197] The skin treatment dressing 403 is a bioactive skin treatment dressing in the form of a hydrocolloid dressing. The skin treatment dressing 403 is made of a flexible light transmission material 481 (see Figure 7 ) is made.

[0198] The light transmissive material 481 comprises one or more light transmissive regions 490 in the form of channels 490. The channels 490 are circular in cross-section and have a diameter of between 0.1 mm and 0.5 mm.

[0199] The light transmission region 490 includes an aperture 491 that is perpendicular to the back of the skin treatment dressing 403 to allow light to be transmitted from the light emitting component 402 to the user's skin without being attenuated by the light transmission material 481 of the skin treatment dressing 403.

[0200] In this regard, the light transmitting regions 490 are configured to provide greater light transmission from the light emitting component 402 to the user's skin compared to other areas of the light transmitting material 481 (ie, areas other than the light transmitting regions 490).

[0201] Thus, light transmission region 490 increases the efficiency of light therapy.

[0202] Furthermore, this increase in efficiency can be provided while allowing the skin treatment dressing 403 to still provide sufficient support to allow the device to remain attached to the skin. In this regard, the light transmission region 490 avoids having to provide increased power and therefore avoids having to use a larger power source, thereby making it easier to attach to the user's skin and making it more comfortable for the user to wear. Again, this can provide the required medical time without having to increase the power of the power source. Furthermore, since no increased power is required, this avoids the increase in heat in the light transmission material 490. Therefore, this avoids the light transmission material from becoming too soft, and therefore the light transmission material does not lose its adhesive properties and thus does not fail to adhere to the user's skin.

[0203] The physical strength of the light-transmitting material 481 is sufficient to attach the light-emitting component 402 to the user's skin and maintain the structural integrity of the light-transmitting material 481 when operated by the user. The inventors have found in testing that this structural integrity requirement can limit the minimum cross-sectional thickness of the light-transmitting material when holes are formed to allow light transmission. The minimum cross-sectional thickness depends on the properties of the light-transmitting material. A high minimum cross-sectional thickness results in an increase in light absorption by the light-transmitting material in areas without light transmission areas, and a subsequent decrease in the light dose delivered to the skin.

[0204] To overcome this problem, Figure 8 In the sixth embodiment shown in , the light transmitting region 590 is the region of the light transmitting material 581 having a smaller cross-sectional thickness 513 .

[0205] Apart from the differences described with respect to the fifth embodiment, the sixth to eighth embodiments are identical to the fifth embodiment. Corresponding features have been given corresponding reference numerals, but increased by 100 with respect to the corresponding previous embodiment.

[0208] refer to Fig.10In an eighth embodiment, the light transmitting material 781 comprises two layers 704, 704' that are combined, each layer having a hole 718 in each layer, and wherein the combined layers are configured such that each hole 718 is offset to provide the light transmitting region 790.

[0209] refer to Figures 11a to 11c , shows a skin disease treatment device 801 according to a ninth embodiment of the present disclosure. Except for the differences described below, the skin disease treatment device 801 of the ninth embodiment is the same as the skin disease treatment device of the first embodiment. Corresponding features are given corresponding reference numerals, but increased by 800.

[0210] The skin disease treatment device 801 of the ninth embodiment includes a plastic upper layer 870 and a flexible cushion layer 871 attached to the lower surface of the plastic upper layer 870. The cushion layer 871 is provided with a hole 876 in which a ring-shaped iron plate 877 is installed. The ring-shaped iron plate 877 is used for charge absorption.

[0211] A thin battery 872 is provided below the cushion layer 871, the thin battery 872 being electrically connected to a printed circuit board 873, and the printed circuit board 873 being mounted below the battery 872. A light source 806 and a control unit are provided on the printed circuit board 873, the light source 806 being an LED 806. A plastic sealing layer 874 is provided below the printed circuit board 873.

[0212] Each of the plastic upper layer 870, the backing layer 871 and the printed circuit board 873 has a general teardrop shape, so that the entire device 801 has a general teardrop shape. This can be advantageous for the area of ​​the user to be treated. Other advantageous shapes can be used, such as a crescent shape on the lips, a circular shape for acne. The skin treatment dressing can be shaped in a manner that allows multiple skin treatment dressings to be positioned adjacent to each other, such as in a hexagonal shape.

[0213] An electrical connector 878 is provided in the plastic upper layer 870 which connects the battery 872 to a power cable 875 for connection to an electrical supply.

[0214] The entire device 801 is flexible and can therefore be comfortably worn by a user. The entire device 801 is also thin. In this regard, the entire device 801 is less than 2 mm thick.

[0218] As described above, in use, the skin treatment dressing is configured so that light from the light emitting component passes through the skin treatment dressing to the user's skin. In this regard, the skin treatment dressing can shield the area undergoing treatment, thereby preventing the user from poking or otherwise interfering with the skin condition, which would slow the healing process, while allowing light from the light emitting component to pass through the skin treatment dressing to provide dermatological treatment. Therefore, the device can provide the advantages of both skin treatment dressings and phototherapy. In this regard, the device can provide the long-term benefits and ease of use of a skin treatment dressing with the immediate results of phototherapy.

[0227] In another embodiment, the skin therapy dressing is applied to the user's skin and light from the light emitting component shines through the skin therapy dressing onto the user's skin while the light emitting component is not attached to the skin therapy dressing.

[0228] In another embodiment, after light from the light emitting component is radiated through the skin therapy dressing onto the user's skin for a certain period of time, the light emitting component is removed from the skin therapy dressing while the skin therapy dressing remains attached to the user's skin for another period of time.
