Description

SYSTEM AND METHOD FOR IRRADIATING A BRAIN AND AT LEAST ONE BODYPART OF A USERTECHNICAL FIELD

[0001] The present invention generally relates to therapeutic devices. More specifically the present invention relates to light or electromagnetic radiation-based therapeutic devices.BACKGROUND ART

[0002] Light therapy devices have been around for a considerable amount of time, with many of these devices being designed to be worn as headbands, face masks, armbands, or waist belts. Typically, these devices are constructed with an opaque outer layer that faces the environment and a transparent inner layer that faces a particular part of the user's body. Several light sources are located between these layers and are positioned to face the user's body part. These light sources may include LEDs, halogen lamps, lasers, or a combination of these sources. Additionally, the method of delivering light to the user's body part may involve continuous or pulsating irradiation, with a relatively constant frequency of pulses.

[0003] However, such devices generally generate singular effects, that is even if more than one device is worn on the body of the user, the devices operate independently of each other and produce minimal effect other than the sum of individual effects of the individual devices. Moreover, few such light therapy devices are designed for generating effects that might be beneficial for the development, maintenance, and repair of brain tissue. Whereas light therapy devices may have several potential positive effects on the brain of the user, improving focus, flow, and performance and treatment of an injury. The light therapy devices may also help in the treatment and / or management of brain -related diseases such as Alzheimer’s Disease (AD), Parkinson’s Disease (PD), and Traumatic Brain Injury (TBI). However, the aforementioned beneficial potential of light therapy devices remains relatively untapped.

[0004] Therefore, there is a need for a system that overcomes the disadvantages and limitations associated with the prior art and provides a more satisfactory solution.OBJECTS OF THE INVENTION

[0059] Embodiments of the present invention disclosure will be described more fully hereinafter with reference to the accompanying drawings in which like numerals represent like elements throughout the figures, and in which example embodiments are shown.

[0060] The detailed description and the accompanying drawings illustrate the specific exemplary embodiments by which the disclosure may be practiced. These embodiments are described in detail to enable those skilled in the art to practice the invention illustrated in the disclosure. It is to be understood that other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the present disclosure. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the present invention disclosure is defined by the appended claims. Embodiments of the claims may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

[0061] It is envisaged that a system and a method be provided that deliver light energy through irradiation of a brain, and a body part, other than the brain, of a user, simultaneously. In that regard, the system may include two or more devices. At least one of the two or more devices is envisaged to be worn as a headband, and at least one to be worn as a body pad. The headband is envisaged to irradiate the forehead and a rear part of the head of the user. The body pad is envisaged to irradiate a body part, other than the head, of the user. For example, the body pad may be adapted to irradiate the gut of the user or the abdomen or the chest or the adipose tissue of the thigh or a limb, etc. The head band and the body pad may also be adapted to irradiate a gut -brain axis of the user, moreparticularly vagus nerve and microbiome of the gut-brain axis. While the brain is getting irradiated by the headband, a synergistic effect is generated on the brain tissue and the gut of the user, such that, the irradiation of the gut enhances brain function which in turn enhances the functioning of the gut, and the irradiation of the brain enhances the functioning of the gut which in turn enhances the brain function. In that manner, the total effect of the irradiation by the system would be significantly higher than the sum of individual and discrete irradiation of the gut and the brain.

[0062] It is further envisaged that the light energy is provided through several light clusters (for example, clusters of Light Emitting Diodes (LEDs) and / or LASERs) in the headband and combinations of light clusters and uniform distribution of LEDs in the body pad. Moreover, it is envisaged that the light energy through the several light clusters and the uniformly distributed LEDs be provided in a pulse mode. The frequencies of corresponding pulses may be designed to be non-uniform to more accurately mimic biological systems. The irradiation through the clusters of light and the uniformly distributed LEDs may be provided to the user in the red or infrared ranges of wavelengths. The system is also envisaged to include a controller that is configured to control the irradiation characteristics of the light clusters and the uniformly distributed LEDs. The controller further may be able to connect with an external computing device, enabling the user to modify the irradiation characteristics with the help of the external computing device.

[0063] The method may include the application of the aforementioned system to the body of the user. In that regard, the method may include attachment of the headband and the body pad to the head and the body of the user, respectively, and activation of irradiation from the light clusters and the uniformly distributed LEDs. The irradiation characteristics of the light clusters and the uniformly distributed LEDs may be controlled through the controller directly or with the help of an external computing device. Referring to the drawings, the invention will now be described in detail.

[0064] Figure 1 illustrates a perspective view of a user wearing a system 100 for irradiating a brain and at least one body part of a user, in accordance with an embodiment of the present invention. The system 100 includes a headband 102 and a body pad 104.The headband 102 has been worn by the user on their forehead, while the body pad 104 has been worn by the user on their abdomen region. However, the body pad 104 may be worn on other parts of the body such as limbs, adipose tissue, gut, etc. without departing from the scope of the invention.

[0065] Figure 2A illustrates a rear perspective view of the headband 102 in accordance with an embodiment of the present invention. The headband 102 includes a front portion 202 and a rear portion 204. The front 202 and the rear 204 portions are connected by a connecting member 206. In several embodiments of the invention, the connecting member 206 may be selected from a group consisting of a rubber strap, a fabric belt, a leather belt, a soft polymer-based belt, a stretchable string, or rigid members with tightening mechanisms. The front portion 202 is adapted to be located on a forehead of the user. The rear portion 204 is adapted to be located on a rear part of the head of the user. Further, the front portion 202 includes a plurality of light clusters 208 oriented towards the forehead of the user. The plurality of light clusters 208 is configured to irradiate the forehead of the user.

[0066] Each cluster of the plurality of light clusters 208 is constituted by several light sources. Such light sources may include but are not limited to, LEDs and lasers. A light cluster is capable of combining the light emitted by all the constituent light sources to deliver light with relatively higher energy density, thereby increasing the penetration of the light emitted by several light sources. Figure 2B illustrates the plurality of light clusters 208 in accordance with an embodiment of the present invention. In the embodiment illustrated in Figure 2B, the plurality of light clusters 208 includes at least three light clusters such as a first light cluster 252, a second light cluster 254, and a third light cluster 256.

[0067] In several embodiments of the invention, the plurality of light clusters 208 of the front portion 202 is configured to emit radiation in red and infrared wavelength ranges of the electromagnetic spectrum. In several embodiments of the invention, the infrared wavelength may predominantly include Near Infrared (NIR) wavelengths. The NIR radiation is known to penetrate the head and reach the brain. Further, NIR radiation is absorbed by cytochrome C oxidase in mitochondria, leading to increased blood flow,energy, neuroprotection, reduction in inflammation, and brain repair. The NIR radiation is known to provide several other benefits which can be studied from the following publication, which is included herein, in their entirety, by reference.

These neuro-systems may be deployed to guide the light energy through deeper portions of the human brain. It has been found through several studies that irradiation of frontal portions of the brain helps in the repair and enhancement of cognitive function and repair of damaged brain cells in patients suffering from diseases like Alzheimer’ s disease and Parkinson’s disease. Further potential applications of the irradiation of the frontal portions of the brain include treatment of Attention Deficit / Hyperactivity Disorder (ADHD), Post Traumatic Stress Disorder (PTSD), Traumatic Brain Injury (TBI), depression, and concussive injuries.

The body pad 104 is adapted to be worn on any one or more body parts of the user, other than the head of the user. For example, the body part irradiated by the body pad 104 may be selected from a group consisting of a gut, a chest, an adipose tissue of the thigh, and a limb of the user. Further, the body pad 102 may be made of neoprene material. In several embodiments of the invention, the body pad 104, in combination of the headband 102, is configured to irradiate the gut-brain axis of the user. It is widely accepted that brain health affects the function of the gut and gut health in turn affects brain function. For example, if a person is suffering from a depressive disorder, they may not have a proper bowel movement, absorption of water, and / or absorption of nutrients in their gut. Similarly, a person suffering from a gut-related disorder such as Irritable Bowel Syndrome (IBS) or Crohn’s disease is more likely to have psychiatric disorders such as depression and anxiety.

[0083] The gut-brain axis consists of bidirectional communication between the central and the enteric nervous system, linking the emotional and cognitive centers of the brain with peripheral intestinal functions. The pathways involved in gut-brain interactions include, but are not limited to, a vagus nerve, neuroendocrine signaling, interference with tryptophan metabolism, hypothalamic -pituitary-adrenal (HPA) axis, endocannabinoid system, and the immune system, and modulation of the microbiome. The system 100 is configured to simultaneously irradiate the brain of the user through headband 102 and the gut-brain axis through the headband 102 and the body pad 104. When the brain is getting irradiated by the headband 102, and the gut-brain axis is being irradiated by the body pad 104, a synergistic effect on the brain tissue and the gut of the user is generated, such that, the irradiation of the gut enhances brain function which in turn enhances the functioning of the gut. Moreover, the irradiation of the brain enhances the functioning of the gut which in turn enhances brain function. In that manner, the total effect of the irradiation by the system 100 would be significantly higher than the sum of individual and discrete irradiation of the gut and the brain.

[0084] The body pad 104, as illustrated in Figure 3A includes a central structure 302 and a belt 304 passing through two openings 311, 313 provided with the central structure 302. The central structure 302 is illustrated to be rectangular in shape, but the central structure 302 can be embodied as any given such as circular, triangular, trapezoidal, etc. The body pad 104 includes a light assembly 325 configured to irradiate the body part of the body on which the body pad 104 has been worn. Further, the light assembly 325 has been disposed at an inner surface 303 of the central structure 302. In several alternate embodiments of the light assembly 325 includes a plurality of uniformly distributed LEDs as illustrated in Figure 3A. Figure 3B illustrates a bottom perspective view of the body pad 104, in accordance with another embodiment of the present invention. In several embodiments of the present invention, the light assembly 325 may include a plurality of clusters of LEDs. For example, the embodiment illustrated in Figure 3B illustrates a cluster of LEDs in the central structure 302 of the body pad 104.

[0085] In several alternate embodiments, the light assembly 325 may include a combination of the plurality of clusters of LEDs in certain sections of the central structure 302 and the plurality of uniformly distributed LEDs in other sections of the body pad 104.For example, one-half of the central structure 302 may be provided with the plurality of clusters of LEDs and another half of the central structure 302 may be provided with the plurality of uniformly distributed LEDs. In another example, the plurality of clusters of LEDs may be interspersed in the gaps between the plurality of uniformly distributed LEDs.

[0086] In several embodiments of the invention, the light assembly 325 is configured to emit radiation in red and infrared wavelength ranges of the electromagnetic spectrum. Further, in several embodiments of the invention, the light assembly 325 is configured to emit radiation with wavelengths lying in ranges of 625 to 635 nm, and 845 to 855 nm. The advantages of red, infrared, and NIR radiation have already been discussed in the preceding discussion. In an example scenario, the body pad 104 may have a treatment dose of 10 ± 1 J / cm2, for the wavelength range of 625 to 635 nm, and a treatment dose of 30 ± 3 J / cm2 for the wavelength range of 845 to 855 nm.

[0087] Figure 3C illustrates a top perspective view of the body pad 104 in accordance with an embodiment of the present invention. The belt 304 is provided with a fastening arrangement 330. In several embodiments of the invention, the fastening arrangement 330 may be selected from a group consisting of loops and hooks based fasteners, buckle type fastening arrangements, snap-fit arrangement type fasteners, etc. The body pad 104 further includes a push button 332 provided on an outer surface 305 of the central structure 302. The push button 332 may act as the at least one controller. In several alternate embodiments of the invention, the body pad 104 may be provided a processor or an SoC based controller. Further, the body pad 104 includes a second communication port 334 similar to, but may or may not be identical to, the first communication port 214 of the headband 102. The second communication port 334 of the body pad 104 may act as a communication interface and / or a port for receiving power from a power source. For example, the second communication port 334 of the body pad 104 may be USB type A, B, or C port, an Ethernet port, or an HDMI port, etc. Further, similar to the first communication port 214, the second communication port 334 of the body pad 104 may be capable of communicating with the external computing device through a wired or wireless network (as will be discussed in the following discussion). In several embodiments of the invention, the at least controller of the body pad 104 may be referredto as a second controller, and the second communication port 334 of the body pad may be referred to as a second communication interface.

[0088] One or more of the first controller of the headband 102 and the second controller of the body pad 104 may be deployed to operate the plurality of light clusters 208 of the front portion 202, the at least one light cluster 210 of the rear portion 204, and the light assembly 225 of the body pad 104, in a pulsed mode. It is envisaged that the pulses of electromagnetic radiation may be provided in a random or semi-random manner. In other words, the frequency of the pulses of electromagnetic radiation would be non-uniform to effectively mimic the inherent flexibility and unpredictability in biological systems. In that regard, frequencies of pulses corresponding to the irradiation from the plurality of light clusters 208 of the front portion 202, the at least one light cluster 210 of the rear portion 204, and the light assembly 325 of the body pad 104, are configured to follow a predetermined frequency protocol.

[0089] In a non-limiting example, the predetermined frequency protocol includes variation of the frequency within a predetermined range about a mean value, the predetermined range is determined by adding and subtracting a fraction of the mean value, to and from the mean value, respectively. In a non-limiting example, the value of the fraction maybe 10 percent. One way to introduce variation in a pulsed light signal would be to use a stochastic modulation method, which adds a random component to the signal. The resulting signal would have an average frequency of 40 Hz, but with fluctuations around this mean value that would introduce variation in the signal. For example, for a mean value of 40 Hz, if the variation was set to 10%, the variation of frequency would be within ± 4 Hz of the mean value of 40 Hz, leading to a randomized deviation from the nominal 40 Hz frequency. This type of randomized delivery has been used in other neuromodulation techniques such as Transcranial Magnetic Stimulation (TMS) and deep brain stimulation, but not in Photobiomodulation.

[0090] Figure 4 illustrates a network diagram 400 depicting data connections between the headband 102, the body pad 104, and an external computing device 404, in accordance with an embodiment of the present invention. The headband 102, the body pad 104, and the external computing device 404 are connected through a network 402. The network402 in that regard, maybe a wired network, a wireless network, or a combination of wired and wireless connections. For example, the network 402 may be implemented through combinations of Ethernet cables, Bluetooth connections, Wireless Fidelity (Wi-Fi) connections, and data connections made through 3GPP protocols such HSPA, HSDPA, LTE, etc. The network 402 allows the first controller to independently communicate with the external computing device 404 through the first communication interface and allows the second controller to independently communicate with the external computing device 404 through the second communication interface.

[0091] At least one of the first controller and the second controller is configured to receive a modification input signal from the external computing device 404 through at least one of the first communication interface and the second communication interface, respectively. The modification input signal may be received for modification of the irradiation characteristics of the one or more of the plurality of light clusters 208 of the front portion 202, the at least one light cluster 210 of the rear portion 204, and the light assembly 325 of the body pad 104. The irradiation characteristics may include but are not limited to, mode of operation, such as continuous or pulsating, frequency of pulses, length and / or time duration of each pulse, etc. The network 402 also allows the first controller to communicate with the second controller, through the first communication interface and the second communication interface. In such a scenario, only one of the first controller and the second controller may need to communicate with the external computing device 404. In an alternate scenario, one of the first and the second controller are configured to communicate with the external computing device 404 and then transmit the modification input signal to the other controller. In an alternate scenario, the control of the system 100 may be divided between the first controller and the second controller.

[0092] The headband 102 and the body pad 104 may be provided with several batteries (not shown) to power the system 100. The headband 102 may be provided with one or more batteries to power the plurality of light clusters 208 of the front portion 202 and the at least one light cluster 210 of the rear portion 204. The body pad 104 may be provided with one or more batteries to power the light assembly 325. Further, the batteries may be rechargeable batteries, such as lithium-ion batteries, lithium-polymer batteries, nickel- metal hydride batteries, etc. The one or more batteries of the headband 102 may becharged through the first communication port 214, and the one or more batteries of the body pad 104 may be charged through the second communication port 334. Moreover, the one or more batteries of the headband 102 have been shielded from any potential effects of Electro -Motive Force(EMF) acting on the one or more batteries.

[0093] Figure 5 illustrates a method 500 for irradiating the brain and the at least one body part of the user. The method 500 begins at step 502 by attaching the headband 102 to the head of the user. The headband 102 includes the front portion 202 including the plurality of light clusters 208, and the rear portion 204 including the at least one light cluster 210. The plurality of light clusters 208 are configured to irradiate the forehead of the user, and the at least one light cluster 210 is configured to irradiate the rear part of the head of the user.

[0094] At step 504, the body pad 104 is attached to the body part of the user. The body part may be selected from a group consisting of the abdomen, the gut, the limbs, and the adipose tissue of the thighs of the user. The body pad includes the light assembly 325. The light assembly 325 may include the plurality of clusters of LEDs or uniformly distributed LEDs or combinations of the plurality of clusters of LEDs and uniformly distributed LEDs.

[0095] At step 506, the gut-brain axis of the user is targeted by synergistic irradiation through the plurality of light clusters 208 of the headband 102, and the light assembly 325 of the body pad 104. In several embodiments of the invention, the rear part of the head of the user may also be irradiated by the at least one light cluster 210. The irradiation has wavelengths lying in red, infrared, and Near Infrared (NIR) ranges of the electromagnetic spectrum. The transcranial irradiation of the brain by the headband 102 and simultaneous irradiation of the body part of the user (such as the gut) provides synergistic therapeutic effects which are greater in efficacy when compared with the sum of individual therapeutic effects of the headbands and the body pads known in the art.
