The present invention relates generally to therapeutic devices. More specifically, but not exclusively, the present invention relates to therapeutic devices that include multiple distinct therapeutic modules that are capable of providing multiple kinds of therapies through a single device, for treating skin related ailments in human beings.
Human skin is the largest organ in a human body, and provides an outer covering to the human body, thereby protecting internal tissues and organs against infection, loss of water in the form of dehydration, and harmful radiations including ultraviolet light and the like. Also, the skin is capable of generating Vitamin D on the absorption of sunlight. Therefore, proper care of the skin is required for the maintenance of good health. External environmental agents and internal body conditions may affect the skin resulting in skin-related disorders or altered skin conditions like wrinkles, sun spots, acne, discoloration, scars, pigmentation, rosacea, actinic keratosis, and unwanted hair growth to name a few. As the characteristics of the skin are also a measure of the aesthetic appeal of individuals, most individuals prefer non-invasive or minimally invasive therapies for the treatment of skin ailments.
With the advancements in Research and Development (R&D) pertinent to therapeutic devices, several novel kinds of non-invasive or minimally invasive therapies have been suggested for the treatment of human skin related diseases and disorders. For example, in light therapy, also known as Low Level Laser Therapy (LLLT), Photo-Dynamic Therapy (PDT) or Photo-Bio-Modulation (PBM), low-intensity lasers and Light Emitting Diodes (LEDs) are used to generate irradiation patterns of desired characteristics. Further, there is an electrical therapy wherein electrical stimulation is used for treating the skin ailments. Here again, low magnitude electric currents are passed through the skin to produce several therapeutic effects, including, but not limited to, toning of muscles in the body and micro-lifting of the face. In vibrational massaging of the skin, mechanical vibrations are used to improve skin conditions and also to reduce stress. However, for using each of the aforementioned treatment methods, there arises the requirement for configuring a dedicated device corresponding to each one of the individual treatment methods.
It has further been observed that while one kind of treatment may be compatible with certain individuals owing to their physiological characteristics such as age, sex, skin type, and pre-existing conditions, etc., the same treatment may not be compatible with another group of individuals with a different set of physiological characteristics. Further, the efficacy of the kind of treatment may also vary as per the variations in the kind of ailments being addressed. For example, while LLLT may be effective in the treatment of acne in Latino individuals, the electromagnetic radiation may not be able to assist as much in pain relief as electrical therapy. Vice versa may be true of Caucasian individuals. Therefore, it might become desirable or rather necessary, to purchase several such devices to address the issues that arise out variations in physiological characteristics and kind of ailments, forcing an individual or a treatment facility to incur excessive expenditure.
Therefore there is a requirement in the art for a multi-module therapeutic device that does not suffer from the aforementioned deficiencies.

It is envisaged here that a multi-module therapeutic device (hereinafter also referred to as “the device”) for skincare be provided that may be portable and capable of being ergonomically held in hands of the user. In that regard, the device may be given a form resembling a computer mouse as it is a widely used article and its utilization would be rather intuitive for a user. The device is further envisaged to include several modules for several different kinds of therapies such as light therapy (also known as Low Level Laser Therapy (LLLT), Photo-Dynamic Therapy (PDT) or Photo-Bio-Modulation (PBM)), vibrational massage therapy, thermotherapy and application of a medicament on affected areas of the skin. Each one of the modules is envisaged to be able to work independently and in tandem with each other thereby providing enhanced therapeutic benefits. It is further envisaged that activation and deactivation of the several modules be possible using easily accessible buttons on a control panel of the device, wherein additional control interfaces may be provided for regulation of the operational characteristics of the several different therapeutic modules.
The device is also envisaged to include capabilities for connecting with a remote communication device for receiving control signals and be able to be charged, through both wired and wireless connections. It is further envisaged that the device is simple in construction and be made of lightweight materials for the convenience of the users using the device. Referring to the figures now, the invention will be described in more detail.
One portion 28A of the sidewall structure 18 encloses the control panel 20 on one side, is adapted to provide support for a thumb of the user, assuming that the user is right-handed, and another portion 28B of the sidewall structure 18 enclosing the control panel 20 on the other side, is adapted to provide the support for the fingers of the user. While the reverse may be true in case the user opts to use the device 10 with their left hand. The housing 14 with the control panel 20 forms a three-dimensional closed curve configuration of the device 10, making the device 10 ergonomic to use.
For actuation of the medicament dispenser 48, the device 10 includes an intermediary piston mechanism 22E. The intermediary piston mechanism 22E includes a piston head 22F and a piston shaft 22G. The piston head 22F and the piston shaft 22G may be made up of rigid polymeric materials, lightweight metals such as aluminum and magnesium, or metal composites, etc. Further, the intermediary piston mechanism 22E includes a compression plate 22I provided at the bottom end of the piston shaft 22G. In several embodiments, the piston head 22F, the piston shaft 22G, and the compression plate 22I may be integrated to form a single functional unit. Integration of the aforementioned components allows them to be injection molded or die-casted in a single manufacturing step thereby reducing the cost of tooling, production, and assembly, had the piston head 22F, the piston shaft 22G, and the compression plate 22I were separately fabricated. Further, the compression plate 22I includes a plurality of medicament apertures 38A. The intermediary piston mechanism 22E further includes a channel plate 22J. A plurality of compression springs 22H has been provided between a bottom surface of the compression plate 22I and a top surface of the channel plate 22J. Also there has been provided a sealing ring 23 configured to provide a leak proof sealing between the compression plate 22I and the channel plate 22J. The sealing ring 23 may be made up of chemical resistant rubber such as Neoprene.
Further, as illustrated in
Commonly used semiconductor materials include nitrides of Silicon, Gallium, Aluminum, and Boron, and Zinc Selenide, etc. in pure form or doped with elements such as Aluminum and Indium, etc. For example, red and amber colors are produced from Aluminum Indium Gallium Phosphide (AlGaInP) based compositions, while blue, green, and cyan use Indium Gallium Nitride based compositions. White light may be produced by mixing red, green, and blue lights in equal proportions, while varying proportions may be used for generating a wider color gamut. White and other colored lightings may also be produced using phosphor coatings such as Yttrium Aluminum Garnet (YAG) in combination with a blue LED to generate white light and Magnesium doped potassium fluorosilicate in combination with blue LED to generate red light. Additionally, near Ultra Violet (UV) LEDs may be combined with europium based phosphors to generate red and blue lights and copper and zinc doped zinc sulfide-based phosphor to generate green light.
The plurality of LEDs 40 may be installed with the PCB 24 through Surface Mount Technology (SMT). SMT permits the creation of smaller PCB designs by allowing components to be placed closer together on the board that makes the device more lightweight and compact. The SMT process is faster to set up for production and requires less manufacturing cost than its counterpart, through-hole technology because it does not require the circuit board to be drilled for assembly. In several alternate embodiments, the plurality of LEDs 40 may be installed with the PCB 24 via through-hole technology. In several embodiments, the assembly of the plurality of LEDs 40 and the PCB 24 may be embodied as flexible LED panels such as Organic LED (OLED) based flexible panels or inorganic LED-based flexible panels.
Such OLED panels may be generated by depositing organic semiconducting materials over Thin Film Transistor (TFT) based substrates. Further, discussion on generation of OLED panels can be found in Bardsley, J. N. (2004), “International OLED Technology Roadmap”, IEEE Journal of Selected Topics in Quantum Electronics, Vol. 10, No. 1, that is included herein in its entirety, by reference. An exemplary description of flexible inorganic light-emitting diode strips can be found in granted U.S. Pat. No. 7,476,557B2, titled “Roll-to-roll fabricated light sheet and encapsulated semiconductor circuit devices”, which is included herein in its entirety, by reference. In several embodiments, the plurality of LEDs 40 may also be micro-LEDs described through U.S. Pat. Nos. 8,809,126B2, 8,846,457B2, 8,852,467B2, 8,415,879B2, 8,877,101B2, 9,018,833B2, and their respective family members, assigned to NthDegree Technologies Worldwide Inc., which are included herein by reference, in their entirety. The plurality of LEDs 40, in that regard, may be provided as a printable composition of the micro-LEDs, printed on the PCB 24 acting as a substrate.
In several embodiments, the plurality of LEDs 40 has been provided with a plurality of respective auxiliary optics 42 configured to adjust beam angle of the electromagnetic radiation emitted by the plurality of LEDs 40. The plurality of auxiliary optics 42 may assist in controlling other emission characteristics of the emitted electromagnetic radiation, such as point of incidence, angle of incidence, intensity, and wavelengths through the interference of two or more beams. In that regard, the plurality of auxiliary optics 42 may include convex lenses, concave lenses, Total Internal Reflection (TIR) lenses, and the like. Further, the housing 14 encloses a vibration motor 25 configured to facilitate a provision of massage therapy. In several embodiments of the invention, the vibration motor 25 is an eccentric mass motor and is coupled with a metal sheet 30 for providing massage therapy. In several alternate embodiments, the vibration motor 25 may be a piezo-electric material based motor. The metal sheet 30 is envisaged to be made up of a lightweight material such as aluminum owing to its superior thermal conductivity and vibration transmissibility. Therefore, the metal sheet 30 is configured to act as a medium for the application of massage therapy and thermotherapy.
In several embodiments, the metal sheet 30 is configured to be heated from heat energy produced by the plurality of LEDs 40. In several alternate embodiments, like the one depicted in
Also, the electrical heating element 26 is in thermal communication with the metal sheet 30, and the vibration motor 25 is mechanically coupled with the metal sheet 30. Also, the device 10 includes a processor 52, a memory unit 54, a communication interface 56, and a power supply unit 58. The processor 52 may be a general-purpose processor, a Field Programmable Gate Array (FPGA) or an Application Specific Integrated Circuit (ASIC), etc. Additionally, the memory unit 54 may be a volatile memory unit such as Static Random Access Memory (SRAM) and Dynamic Random Access Memory (DRAM) of types such as Asynchronous DRAM, Synchronous DRAM, Double Data Rate SDRAM, Rambus DRAM, and Cache DRAM, etc.
The communication interface 56 is configured to allow the device 10 with other communication devices through a shared network. In that regard, the communication interface 56 may include ports such as Universal Serial Bus (USB) port, Video Graphics Array (VGA) port, and High Definition Multimedia Interface (HDMI) port for wired connections. The communication interface 56 may also include modems for wireless communication, such as a Wireless Fidelity (Wi-Fi) modem for data transfer or a GSM modem for mobile telephony, and GPRS modems for connecting to the Internet or other Wide Area Networks through protocols standardized by 3GPP. The power supply unit 58 may be a rechargeable or a replaceable battery. The rechargeable batteries may be made out of Lithium-Ion or Lithium-Polymer based technologies, Nickel Metal Hydride batteries and the like, that may be capable of being charged through wired or wireless means.
Further, it can be seen from
For example, the processor 52 may regulate emission characteristics such as intensity and pulse width of the electromagnetic radiation by deploying an LED pulse width modulator 72. Further, the processor 52 may regulate the characteristics of thermotherapy, such as temperature and rate of heat transfer, etc. by deploying the LED pulse width modulator 72 and/or the potentiometer 76. Similarly, the processor 52 may regulate the characteristics of vibration massage therapy, such as amplitude and frequency of vibrations, by deploying a motor pulse width modulator 74. Also, the processor 52 may control the flow rate of the medicament from the medicament reservoir 47 by deploying a control valve 78. However, a person skilled in the art would appreciate that there are several alternative open-loop and closed-loop control strategies that may be deployed to regulate characteristics of the aforementioned therapies without departing from the scope of the present invention. The following description elucidates the actuation of the medicament dispenser 48 for dispensing the medicament to the skin of the user.
While using the device 10, the user may press any one or more of the first button 22A and the second button 22B. The processor 52 executing machine-readable instructions stored in the memory unit 54 would then receive an actuation input from the control panel 20 to actuate one or more of the vibration motor 25 and the plurality of LEDs 40. Additionally, the user may also rotate the scroll-wheel of the third button 22C to actuate the medicament dispenser 48 via the intermediary piston mechanism 22E. Further, the processor 52 would receive one or more of the irradiation control signal from the irradiation control interface 60A, the medicament-flow control signal from the medicament flow control interface 60D, the vibration control signal from the vibration control interface 60B and the temperature control signal from the temperature control interface 60C. Depending upon the actuation of the first 22A, the second 22B and/or the third 22C buttons and the irradiation control signal, the medicament flow control signal, the vibration control signal and/or the temperature control signal, the processor 52 would facilitate the performance of one or more of the following tasks. The tasks would include modifying the emission characteristics of the irradiation emitted by the plurality of LEDs 40, modifying the flow rate of the medicament from the medicament dispenser 48, modifying the vibration characteristics of the vibration of the metal sheet 30 and modifying the temperature of the metal sheet 30.
