Definitions

  • the present invention generally relates to a module and a modular system for photo- therapeutic treatment of the epidermis, and more particularly to targeted ultraviolet therapy for treatment of various skin conditions.
  • the module uses targeted narrowband UVB phototherapy to treat dermatoses such as psoriasis, vitiligo, leukoderma, atopic dermatitis, alopecia greata among others.
  • the skin treatment system comprises a plurality of skin treatment modules, wherein each skin treatment module comprises one or more light emitting diodes, LEDs, configured to emit light at a wavelength of between 280 nm and 340 nm, preferably between 290nm and 320 nm, and more preferably between 305nm and 315 nm; a module housing within which the one or more LEDs are arranged, wherein a first side of the module housing comprises a cover, wherein the cover is transparent to the wavelength of the one or more LEDs; a module control board coupled to the one or more LEDs and configured to control the one or more LEDs; and one or more sensors coupled to the module control board, wherein the module control board is further configured to monitor one or more parameters relating to the skin treatment module (in particular the one or more LEDs) and/or the user via the one or more sensors, wherein the one or more sensors are configured to measure (one or more of)
  • the use of LEDs is preferred due to their small and compact size, steady wavelength and intensity output as well as their long lifetime.
  • the LEDs operate in a wavelength of between 280 and 340nm.
  • the LEDs operate between 290 and 320mn, in particular between 305 and 315nm.
  • the peak wavelength of the one or more LEDs is 311 nm.
  • the skin treatment module further comprises one or more LEDs that are configured to emit visible light. This may allow for the user to have an easy visual indication that the skin treatment module is operating.
  • the transparent cover of the module housing is permeable (transparent) to UVB light and is preferably on the side of the skin treatment module that contacts the skin of the user during treatment. This allows for the UVB light to come into contact with the skin while ensuring the light does not escape the module housing in other directions. Therefore, in some examples, only the cover is transparent to the wavelength of the LEDs, while other parts of the module housing are not transparent to the wavelength of the LEDs. If the light is not directed towards the skin, it may result in damage to the eyes of the user or other people in the same room as the user.
  • the transparent cover may also diffuse the light emitted by the LEDs which may result in a better (even) coverage of light and therefore an improved treatment.
  • the section of the module housing on the side of the housing that contacts the skin is U-shaped or substantially U-shaped.
  • the housing side may be V-shaped or substantially V-shaped, flat or any other suitable shape.
  • the module housing is made from plastic that is non-permeable to UVB light or any other suitable non-permeable material.
  • the module control board is configured to control the intensity, of the LEDs and may also turn various LEDs on and off depending on the input to the module control board. Furthermore, the module control board may be configured to monitor parameters relating to the LEDs. The parameters may be the electric current and/or voltage output of the LEDs and/or the capacitive touch of the user in relation to the cover and/or temperature of the skin treatment module and/or user and/or infrared radiation emitted by skin treatment module and/or the user and/or distance of the skin treatment module from the user and/or movement of the skin treatment module in relation to the user and/or any other suitable parameter. In some examples, the LEDs are switched on and/or off by the module control board if the current being measured falls outside particular predetermined limits.
  • the LEDs may also be switched on and/or off if the measured temperature increases (and/or decreases) by a value more than a predetermined delta.
  • the LEDs may be switched on and/or off if the distance between the skin treatment module and the user's skin is more and/or within a certain threshold. Additionally or alternatively, the process of switching the LEDs on and/or off may occur when the one or more parameters of each of the one or more sensors are within and/or outside a predetermined condition.
  • the switching of the LEDs may allow for a particularly safe module as the module may switch these LEDs off in order to keep the user safe.
  • Measuring the distance between the skin of the user and the skin treatment module may ensure that the skin treatment module is in contact, or in close proximity (for example within 1, 2, 3 ... or 10 mm or cm) to the skin of the user.
  • the module control board may only turn on the LEDs when a certain threshold has been reached which indicates that the skin treatment module is in contact with the skin of the user or within the above-indicated proximity from the skin of the user.
  • the proximity may be adjustable, in particular if different wavelengths are used for a particular treatment with the skin treatment module.
  • the skin treatment module only turning on in the above-specified cases may lead to a reduced chance of, for example, eye damage for the user, as described above.
  • the skin treatment module may only switch on when it is detected that the skin treatment module is in contact with the skin. In other examples, the skin treatment module may switch on when the skin treatment module is in near contact, e.g. 1mm from the skin. This threshold can be changed based on the wishes of the user or another operator.
  • the module control board may measure the temperature of the skin of the user and/or the skin treatment module. This may allow for the module control board to sense if the light is too intense and if the device begins to emit too much heat, for example, in order to prevent burning of the user's skin and/or the overheating of the skin treatment module. Resultantly, the module control board may automatically reduce the intensity of the LEDs and/or switch one or more LEDs completely off in order to reduce the temperature.
  • the skin treatment module further comprises an infrared sensor which measures the infrared radiation emitted by the skin treatment module and/or user skin contacted by the skin treatment module. This may also be used as a backup to the temperature sensor.
  • the combination of measuring the temperature, the distance and the movement in combination with the switching off of the LEDs may be particularly advantageous with regards to the safety of the user. The combination of these measurements may allow for a very low probability of the user accidentally viewing the UVB light emitted by the LEDs and therefore lead to a reduction of the likelihood of eye damage to the user.
  • the temperature parameter is measured/measurable (only) when the skin treatment module is within a predetermined distance of the user, as measured by the one or more sensors configured to measure the distance of the skin treatment system from the user. This may allow for a reduction in erroneous readings of the temperature sensor, thereby leading to an improved module.
  • the distance is measured/measurable (only) when the temperature of the skin treatment module, as measured by the one or more sensors configured to measure the temperature of the skin treatment module, is above (and/or below) a threshold temperature. This allows for warning the user of the distance between the skin treatment module and the user being too small in case the temperature of the skin treatment module is too high, which may result in the user being burnt. Safety of the skin treatment system is thereby enhanced.
  • the movement of the skin treatment module in relation to the user is measured by an accelerometer and/or a gyroscope. If the skin treatment module moves too much (e.g. too fast and/or too far), it may indicate that it is not secured to the user properly and is in danger of falling off. This may be particularly advantageous in situations where the user is doing sport while wearing the skin treatment module.
  • the accelerometer and/or the gyroscope may additionally or alternatively be any sensor that sufficiently measures movement of the skin treatment module.
  • the one or more sensors are further configured to measure one or more of a capacitive touch of the user in relation to the cover, an output of the intensity of the one or more LEDs, and an electrical current and/or voltage output of the one or more LEDs.
  • the measuring of the capacitive touch may be a backup to the distance measurement sensor.
  • the measurement of the intensity of the LEDs may allow for the LEDs to be switched off, as is described above, in case the LEDs begin to emit the UVB light too intensely.
  • the switching off of the LEDs in this scenario may result in a lower likelihood for the user to be burnt by the LEDs and also extend the lifetime of said LEDs.
  • the measurement of the current and/or voltage of the LEDs may allow for the LEDs to be switched off if the measurements fall outside of predetermined thresholds. If they fall outside predetermined thresholds, it may indicate that the LEDs are malfunctioning and then they can be turned off in order to protect the user.
  • the transparent cover of the module housing can be a partially or completely adjustable form factor, i.e. flexible.
  • the transparent cover being flexible or at least partially flexible may allow for the skin treatment module to adapt to the body part the skin treatment module is treating, such as an arm or a leg. This may result in an improved treatment of the user.
  • the flexibility of the cover may be able to be altered via one or more switches on the outside of the module housing which allows for the cover to become flexible or fix it in place. Additionally or alternatively, the cover may be able to become more or less flexible by swapping the cover for a different cover with a different flexibility. Alternatively, the cover may be wholly rigid or wholly flexible.
  • the cover is completely flexible. This may allow for the cover to be fully customizable to the body part the skin treatment module is treating, as it may allow for the cover to be in direct contact with the skin. It may also allow for a reduction in the light that escapes into the surroundings, thereby improving the efficiency of the treatment and the safety of the user.
  • the skin treatment module further comprises a communication unit coupled to the module control board, wherein the communication unit is configured to send data relating to the one or more sensors to an external controller and/or receive data relating to the one or more sensors from the external controller.
  • This may allow for the data to be examined at an external location and allow the user or operator at the external location to alter, for example, the intensity of the LEDs or any other suitable parameter involved with the treatment process. This in turn may result in a more customized and improved user experience.
  • This external controller may be coupled to the communication unit either wired or wirelessly. The data may be transferred to the communication unit via Wi-Fi, Bluetooth or any other suitable method.
  • the external controller is a mobile device with an application configured to communicate with the communication unit. This allows for the user to personally customize their treatment plan. Additionally or alternatively, it may allow for the user to be sent notifications for when they should begin their treatment if the app stores the treatment plan.
  • the skin treatment module comprises an electrical connector which is configured to electrically and mechanically couple the skin treatment module to an external device. This may allow for the skin treatment module to be coupled to an external device to send data to said device while also being mechanically secured to the device.

  • the module control board comprises a processor configured to process the one or more parameters received from the one or more sensors and a memory configured to store the output of the processor, and in particular wherein the memory stores a predetermined condition for each of the one or more parameters.
  • the processor may parse the results received from the one or more sensors and alter the LEDs via the module control board in real time in order to keep the parameters within predefined thresholds.
  • the memory may store the parsed information and store incidents when the one or more parameters fell (and/or fall) outside their respective predefined thresholds.
  • the memory may store information that can then be transferred to the external controller.
  • the predetermined condition or conditions may be stored within the memory and be fixed throughout the lifetime of the module.
  • the conditions may be altered by the user in particular, in some examples, via a wired and/or wireless connection to an external device, wherein the external device has the ability to change the conditions.
  • the predetermined condition(s) may be stored externally to the skin treatment system.
  • the skin treatment system may communicate with an external device in which the predetermined condition(s) is (are) stored, and where the parameters measured by the sensor(s) may be sent for external evaluating the parameters) in relation to the predetermined condition(s).
  • a signal may be sent from the external device to the skin treatment system in case the user/operator should be warned if one or more of the one or more parameters fall outside the predetermined condition.
