FIELD OF THE INVENTIONThe present invention relates to methods and apparatus for regulating body temperature, and for applying low level light therapy (LLLT), also known as photobiomodulation, over tissue to improve immune function, blood rheology, to regulate sleep and reduce jetlag symptoms, to improve athletic performance, and reduce inflammation, and for neuromodulation/sense of well-being, to improve homeostasis in the body, and for applying LLLT over injuries and lesions to improve wound and soft tissue healing, and to provide relief for acute and chronic pain. The invention is also directed to a portable and convenient apparatus with a user interface, and a system and methodology by which the user can self-administer light and facilitate cooling of the body/blood without any need for medical or technical supervision.
BACKGROUND OF THE INVENTIONOne of the earliest studies of blood irradiation therapy was published in 1981 by Russian scientists, i.e., Mishalkin, E., editor, “Application of direct laser irradiation in experimental and clinical heart surgery (in Russian),” Novosibirsk: Nauka. The studied technique required insertion of a cannula that contained a plastic laser catheter into a vein in the forearm of a human patient, and feeding the low intensity laser light into the blood stream through the cannula. This was an early mode of treatment of cardiovascular diseases, in which both the microcirculation and the rheological properties of blood were improved.
Later published studies further demonstrated that blood rheology can be improved particularly with green or blue wavelengths of laser light (see, Mi, et al., “A comparative study of 632.8 and 532 nm laser irradiation on some rheological factors in human blood in vitro,” Journal of Photochemistry and Photobiology, 74:1: 7-12 (2004); and Gasparyan, L, “Laser irradiation of the blood.” Laser Partner Clinixperience, 58 (2003)).
Later reported studies also suggested that it does not matter if the light energy is coherent (i.e., laser light), but that the light energy instead be of an effective wavelength and be delivered at the correct dosage. For example, incoherent red from a Light Emitting Diode (LED) is expected to perform as well as laser light to produce low-power laser clinical effects; and the primary difference between laser light and LED light is that the laser's coherent beam produces “speckles” of relatively high power density which can cause local heating of inhomogeneous tissues (see, Karu, T. L. “The Science of Low Power Laser Therapy,” Gordon and Breach Scientific Publications, London (1998)). Other studies/reports have described additional benefits and aspects of LLLT (see e.g., Michael R. Hamblin, “Mechanisms of Low Level Light Therapy,” (2008); Scott Roberts, “LED Light Therapy”; and Tiina Karu, “Action Spectra, Their Importance for Low Level Light Therapy”). The studies have also shown that use of 405-450 nm wavelengths (the violet-blue region of the spectrum) are effective with respect to cytochrome c-oxidase.
The studies have also shown that the basis for the effectiveness of the wavelengths of the LLLT relates to quantum mechanical theory (QMT), in that per QMT, light is composed of photons, the energy of which depends upon its wavelength. The photons of the light directed onto living tissue will either be absorbed or scattered, and only the photons that are absorbed may interact with the living tissue. The absorbed photons, typically for the red and NIR wavelengths, may interact in one of three ways—i) the energy of the photon may create heat; ii) the molecular absorption of a photon may result in emission of a different photon having a longer wavelength; or iii) the photon may trigger any one of a number of processes known as photochemistry, which is particularly relevant for the blood.
The normal circulating blood, i.e., blood containing non-aggregated red blood cells (RBCs), performs many important life functions in the mammalian body. Blood provides a supply of oxygen to living tissues via the hemoglobin internally carried by RBCs. Blood provides a supply of nutrients such as glucose, amino acids, and fatty acids. These nutrients are dissolved in the blood or are bound to plasma. Blood acts to remove waste products such as carbon dioxide, urea, and lactic acid. Blood performs diverse immunological functions, including the circulation of multiple kinds of white blood cells, as well as the detection and binding of foreign material by antibodies. Blood provides the cascade of proteins needed for blood clotting or coagulation as part of the body's self-repair mechanisms. Blood provides the entities for messenger functions, including the transport of hormones and the chemical signaling of tissue damage. Blood serves to regulate body pH via blood acidity. Blood regulates the core body temperature. Blood also performs many hydraulic (fluid mechanical) functions.
A blood sample from an unhealthy subject shows that his/her red blood cells may be joined together and form an aggregate, and the presence of such RBC aggregates creates “high viscosity” and a marked resistance to low for the circulating blood in that individual. The aggregated RBCs in blood of such an unhealthy subject would form irregular clusters or masses of cells, causing at least some functional roles of blood to become severely compromised. It is therefore medically desirable and clinically therapeutic if such RBC aggregates in the circulating blood could be made to dissociate and disaggregate into separated and individual red blood cells.
The present invention is particularly configured to provide portable biostimulation using low level light therapy (LLLT), also known as photobiomodulation, at particularly beneficial wavelengths, using particular power levels and pulsing at a duty cycle for the application of the necessary amount of energy, at an optimal delivery location to achieve in-vivo reversal of red blood cell aggregation, without invading the tissues or organs of the living subject—a clinical result which leads to a lower blood viscosity and improved blood circulation. In one embodiment of the present invention, light energy is configured for location-specific delivery using a bracelet to irradiate arterial and venous blood located beneath the skin of the wrist/forearm (e.g., the radial and ulnar arteries). The present invention may also be advantageously utilized upon any other region of the body, and thus may be similarly adapted and directed to use on the neck, the torso, or any other portion of any of a person's limbs, including, but not limited to, the foot, ankle, calf muscle, knee, thigh, etc. In addition the components described herein may also be utilized in a helmet-like/helmet worn device to be worn on the person's head for treatment thereto. Therefore, any description hereinafter that is described with reference to the wrist region, is not intended to be limited to such applicability.
The vasculature lying adjacent to the wrist is particularly receptive to biostimulation. The quantity of blood flow at that location is quite large; and the rate of blood flow is routinely higher per unit area of tissue in comparison to the rate of blood flow into other anatomic locales such as the brain, or the liver, or the muscles. Therefore, the therapeutic benefits of such irradiation light therapy are quickly spread throughout the whole body via the blood circulation system.
The benefits of the particular red wavelength(s) of light used herein are: a) the wavelength(s) are readily absorbed by the mitochondria and stimulatory therein; b) the wavelength(s) also stimulate growth; c) the wavelength(s) do not penetrate deep below the skin surface and into the tissue below; d) the wavelength(s) are non-thermal, and therefore do not create any burns.
The benefits of the infrared wavelength(s) used herein are: a) the wavelength(s) are absorbed through the cell walls (acting differently between cells) and therefore cell response is more wavelength specific, responding differently to different wavelengths; and b) the wavelength(s) are more penetrative through the tissue, for treatment through intact skin, possibly being more stimulatory than red light.
The wavelength(s) in or near the start of the ultraviolet spectrum used herein are particularly beneficial, as it has been shown that both the light frequencies in the red and infrared range most typically used in LLLT as well as wavelengths in the violet and blue range, may influence the localized production and release of nitric oxide, and may stimulate vasodilation through the effect of the nitric oxide on cyclic guanosine monophosphate (cGMP), which is a cyclic nucleotide derived from guanosine triphosphate (GTP), which acts as a messenger, and is regarded as an activation mechanism for intracellular protein kinases. The bracelet (or any other form) of the present invention is therefore designed to be effective for patients who would benefit from increased localized nitric oxide availability, and thus may include wavelengths at and/or in the ultraviolet spectrum, and also blue wavelengths of light. Also, Tiina Karu notes the following in “Action Spectra, Their Importance for Low Level Light Therapy”):
-
- “Recall that in the wavelength range 310-500 nm, a maximum stimulating effect was obtained with a radiation dose one order of magnitude less than in the longer-wave spectral range (3, 4). This is noted in
FIG. 3 by Curves 1 and 2. The bands in the action spectrum were identified in (20, and reviewed in 9) by analogy with the metal-ligand systems absorption spectra characteristic of this spectral range. The regions 400-450 nm and 620-680 nm are characterized by the bands pertaining to complexes with charge transfer in a metal-ligand system, and within 760-830 nm, these are d-d transitions in metals (21-23). The region 400-420 nm is typical of π-π* transitions in a porphyrin ring (24).”
- “Recall that in the wavelength range 310-500 nm, a maximum stimulating effect was obtained with a radiation dose one order of magnitude less than in the longer-wave spectral range (3, 4). This is noted in
Research has shown that to be efficacious, the intensity of the light applied to treat injuries at a skin surface may preferably be between 4 mW/cm2 and 15 mW/cm2, which would require, assuming 5% penetration through the skin, application of light at an intensity of 80 mW/cm2 at the low end (net penetration of 4 mW/cm- and an intensity of 300 mW/cm2 at the high end (net penetration of 15 mW/cm2). It has furthermore been found that apart from the deleterious effect of heating, that long duration pulses may not be optimal for treatment, i.e., pulses such as 50 microsecond on and 250 microsecond off (less than a 50% duty cycle), with an average intensity of 30 mW/cm2 may desirably provide a total of 180 mW/cm2 during each 50 microsecond cycle.
The Mammalian body temperature is normally controlled by an internal autonomic regulatory system referred to herein as the thermoregulatory system. Normally, when body and or environmental temperatures are high, dilation of certain blood vessels favors high blood flow to the noted heat exchange surfaces, thus increasing heat loss to the environment and temperature reduction in the deep body core region. Conversely, as environmental and/or body temperatures fall, vasoconstriction reduces blood flow to these surfaces and minimizes heat loss to the environment.
However, there are situations in which it is desirable to manipulate the transfer of heat across skin surfaces, to modulate the body temperature, where particular applications may include the treatment of normal and abnormal physiological conditions, e.g., disease and/or discomfort, particularly for alleviation or treatment of hot flashes, treatment of exercise or work induced hyperthermia, treatment of stroke, treatment of cystic fibrosis symptoms, treatment of multiple sclerosis symptoms, and the like. By “treatment” it is meant that it results in at least an alleviation in one or more of the symptoms associated with the condition being treated, e.g. a reduction in discomfort, amelioration or elimination of symptoms, etc. Core body cooling (or heating) may be useful not only for therapeutic treatment regimens, but also as a component of improving athletic or industrial performance. Where the herein disclosed device is also used for body temperature regulation during a workout, it may serve: to increase exercise efficiency and capacity; to extend exercise times including longer time to reach 50% strength reduction; to help the user to achieve a higher peak force in resistance training; to lower creatine kinase blood levels (muscle damage index); to naturally and safely stimulate the production of body and brain chemicals that increase physical energy and to attain a sense of well-being derived from the release of certain neurotransmitters such as serotonin and dopamine.
Therefore, another aspect of the present invention is its ability to manipulate the transfer of heat across skin surfaces to modulate body temperatures. The device may include a cooling apparatus, such as a cold pack, an ice pack, or a thermoelectric cooling unit, positioned in proximity to the skin of the wearer of the device. The device may be configured to provide thermal pulses to the wearer's skin surface (e.g., a 33% duty cycle @120 seconds-30 second on and 90 seconds off, or instead, may preferably be a 120 second cycle, with 20 seconds on and 100 seconds off).
In some cases, the average rate of the initial temperature adjustment may be greater in magnitude than the average rate of the return temperature adjustment. Also, the thermal pulse may include a first temperature adjustment at the region of the at least one thermoelectric unit adjacent the skin surface from a first temperature to a second temperature at a first average rate of between about 0.1° C./sec and about 10.0° C./sec, and a second temperature adjustment from the second temperature to a third temperature at a second average rate of between about 0.1° C./sec and about 10.0° C./sec, wherein a difference in magnitude between the first temperature and the third temperature may be less than 25% of a difference in magnitude between the first temperature and the second temperature.
SUMMARY OF THE INVENTIONThis Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
In accordance with at least one embodiment of the present invention, a bracelet may be configured for therapeutic blood irradiation at a first wrist region of the user using a first treatment module, and for body temperature regulation at a second wrist region of a user using a second treatment module. Alternatively, the first treatment module may operate to provide body temperature regulation and the second treatment module may operate to provide therapeutic blood irradiation, and further still, an embodiment of the device (e.g., for the neck) may have a single module configured to provide both therapeutic blood irradiation and the body temperature regulation. It will be understood, therefore, that either the first or the second treatment modules may have either a body temperature regulation and/or a therapeutic blood irradiation function. Accordingly, for purposes of illustration only, in the remainder of the description of the present invention herein, reference may be made to the first treatment module in connection with therapeutic blood irradiation and the second treatment module in connection with body temperature regulation functions, without intending to so limit the present invention to only one such embodiment.
A connector band may flexibly couple the first treatment module to the second treatment module, for positioning on the wearer's wrist, and the connector band may be further configured to electrically couple the second treatment module to the first treatment module. The flexible connector hand may include means for adjusting a length of the band, to accommodate different size wrists for different size users. An attachment band may be fixedly secured to the first treatment module, and may be configured for a portion thereof to be releasably coupled to the second treatment module, so that the user may attach the bracelet to his/her wrist. The attachment band may be formed of a thermoplastic elastomer, and may also be configured to be adjustably coupled to the second treatment module, to further accommodate different wrist sizes.
The first treatment module may broadly include one or more light sources configured to emit one or more selective wavelengths of light from a first side of the first treatment module. The one or more light sources may be LEDs, quantum dots, and/or laser diodes. The one or more light sources of the first treatment module may be positioned to provide therapeutic blood irradiation over a predefined area. The one or more light sources may be configured to generate light at any wavelength within each of the ultraviolet, the visible, and the infrared spectrums (i.e., the one or more light sources can generate an unlimited number of wavelengths). In one embodiment, the one or more light sources may emit the selective wavelengths of light within the range of about 350 nm to about 1000 nm, and may preferably emit the selective wavelengths of light within the range of about 450 nm to about 850 nm. More preferably, the one or more light sources may emit wavelengths of light selected from: about 450 nm, about 532 nm, about 630 nm, about 660 nm, about 660 nm, and about 850 nm. Use within this specification of the relative term “about” in connection with a numeric value is intended to mean 20% of the stated numeric value; therefore the one or more light sources may emit wavelengths of light selected from: 450 nm±20 nm, 532 nm±20 nm, 630 nm±20 nm, 660 nm±20 nm, 660 nm±20 nm, and 850 nm±20 nm. In one embodiment, the one or more light sources may emit wavelengths of light at the wavelengths of 850 nm, 660 nm, 630 nm, 532 nm, and 450 nm. The one or more light sources that may emit the light at the 850 nm and the 660 nm wavelengths/ranges may use a total amount of power in the range of about 300 mW to about 500 mW, and may, in one embodiment, use a total of 415 mW. The one or more light sources that may emit the light at the 630 nm, the 532 nm, and the 450 nm wavelengths/ranges may use a total amount of power in the range of about 300 mW to about 500 mW, and may, in one embodiment, use a total of 335 mW.
Examples of the lights that may be used include IR LED's (a descriptive name) sold under the trademark names of: OSRAM: SFH 4253-Z, OSRAM: SFH 4716AS, VISHAY VSMY3850-GS08, EVERLIGHT ELECTRONICS HIR-C06/L298-P01/TR and QT BRIGHTTEK: QBHP684U-IRU.
Other examples of the lights that may be used include red (e.g., 660 nm) LED's (a descriptive name) sold under the trademark names of: OSRAM: LH CPDP-2T3-1, OSRAM: LH W5AM-1T3T-1-Z, LUMILEDS: LXZ1-PA01, EVERLIGHT ELECTRONICS: ELSH-Q91E-01LPNM-JD3D8, CREE XP-E and CREE: XQEPHR-00-0000-000000901.
Further examples of the lights that may be used include RGB LED's (a descriptive name) sold under the trademark names of: OSRAM: LE RTDUW S2W, OSRAM: LRTDC9TP-EAFB-GHQN, KINGBRIGHT: AADI-9090BRGC-01/3, CREE XM-L, and LED ENGIN Inc.: LZP-00MD00-0000.
Still further examples of the lights that may be used include UV LED's (a descriptive name) sold under the trademark names of: BIVAR: SM0603UV-400, LITE-ON: LTPL-C034UVH405, VISHAY: VLMU3100-GS08 and LUMILEDS: LHUV-0400-0400
In one embodiment, the one or more light sources of the first treatment module may be a plurality of lights sources that are configured to emit the 850 nm wavelength/ranges of light, a plurality of lights sources configured to emit the 660 nm wavelength/ranges of light, and a plurality of lights sources configured to emit the 630 nm, 532 nm, and 450 nm wavelengths/ranges of light. The plurality of lights sources configured to emit the 850 nm wavelength/ranges of light may be distributed in three rows to provide irradiation over a desired area, which in one embodiment may be a substantial portion of a 25 square centimeter area. The plurality of lights sources configured to emit the 660 nm wavelength/ranges of light may also be distributed in three rows to provide irradiation over a substantial portion of the 25 square centimeters. Furthermore, the plurality of lights sources configured to emit the 630 nm, 532 nm, and 450 nm wavelengths/ranges of light may be positioned in a row that may be oriented to be substantially perpendicular to a line between the flexible connector band and the flexible attachment band (i.e., it may be oriented along the axis of the device—being parallel to the arm of the user when worn on his/her wrist).
The second treatment module may broadly include a cooling device, such as a cooling pack (i.e., a bag configured to separate water from ammonium nitrate, calcium ammonium nitrate, or urea, whereby agitating the bag causes mixing of the components to produce an endothermic reaction, and thus cooling), an ice pack, and/or a thermoelectric cooling (TEC) unit, which may be configured to draw away heat and thereby cool a first side of the second treatment module. A gasket may be positioned around a side of the cooling unit, and may be thermally insulating to better ensure the directionality of the heat transfer from one side of the TEC to the other side. Also, a thermally conductive material may be positioned on at least a portion of the first side of the second treatment module, to more effectively draw heat away from the wearer's wrist and towards the first side of the cooling unit. A heat sink may furthermore be used to draw heat away the second side of the thermoelectric cooling unit towards a second side of the second treatment module, to be dispersed therefrom. A peel and stick disposable cushion may be releasably secured to the first side of the second treatment module.
The cooling unit in the second treatment module may be substantially centered therein. The second treatment module may also broadly include a first row of light sources on a first side of the cooling unit, and a second row of light sources on a second side of the cooling unit, with each of the two rows oriented to be substantially perpendicular to a line between the connector band and the attachment band (i.e., being oriented along the axis of the device—being parallel to the arm of the user when worn on his/her wrist). These first and second rows of light sources in the second treatment module may thus be respectively positioned to achieve optimal penetration to the radial and ulnar arteries in the wearer's wrist, and may be configured to emit light at a wavelength of 405 nm.
The bracelet may also broadly include an LED screen, and a microprocessor that may be coupled to the LED screen, the cooling unit, and the light sources. Firmware and/or software implemented therein may cause the display of a Graphical User Interface (GUI) on the LED screen, to permit selection by the user from one or more preprogrammed treatment protocols and/or a customized treatment option, where the customized treatment may permit selection of a treatment time, a cooling temperature, and a light intensity for each of the wavelengths.
The first side of the first treatment module may have a contoured surface configured to roughly conform to the posterior (dorsal) aspect of the wearer's wrist, and the first side of the second treatment module may have a contoured surface configured to roughly conform to the anterior (ventral) aspect of the wearer's wrist. The contoured surface may also be configured to suitably be applied to the person's ankles, or neck, or other body region, which may be accommodated by a band extender.
The bracelet may be configured to be powered by a 2000 mAh, 7.4 V lithium polymer battery, which may be configured to provide adequate power for body temperature regulation and therapeutic blood irradiation for any of the desired treatment protocols, which may be for a portion of an hour, for a full hour, or even longer.
The description of the various example embodiments is explained in conjunction with appended drawings, in which:
As used throughout this specification, the word “may” is used in a permissive sense (i.e., meaning having the potential to), rather than the mandatory sense (i.e., meaning must). Similarly, the words “include”, “including”, and “includes” mean including but not limited to.
The phrases “at least one”, “one or more”, and “and/or” are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions “at least one of A, B and C”, “one or more of A, B, and C” and “A, B, and/or C” mean all of the following possible combinations: A alone; or B alone; or C alone; or A and B together; or A and C together; or B and C together; or A, B and C together.
Also, all references (e.g., patents, patent publications, and non-patent literature) that are cited within this documents are incorporated herein in their entirety by reference.
Furthermore, the described features, advantages, and characteristics of any particular embodiment disclosed in this specification, may be combined in any suitable manner with any of the other embodiments disclosed herein.
In accordance with one embodiment, a bracelet of the present invention may be configured for therapeutic blood irradiation at a first wrist region of the user using a first treatment module, and for additional therapeutic blood irradiation at a second wrist region of a user using a second treatment module. In another embodiment, the bracelet may be configured for therapeutic blood irradiation at the first wrist region using the first treatment module, and for body temperature regulation at the second wrist region using the second treatment module. In yet another embodiment, the bracelet may be configured for therapeutic blood irradiation at the first wrist region using the first treatment module, and for additional therapeutic blood irradiation and body temperature regulation at the second wrist region using the second treatment module.

In one embodiment, the RGB lighting provided by the range of wavelengths about 630 nm, 532 nm, and 450 nm may be replaced by light sources configured to emit only light at the green and blue wavelengths (i.e., the 532 nm, and 450 nm wavelengths/ranges), or the 630 nm wavelength light sources may instead be inactivated, if desired.

The light sources and electronic components of the first treatment module 100 may be powered using an electrical cord and plug that may be connected to a wall outlet to receive power therefrom. Alternatively, the bracelet 10 may be configured to be powered by a battery 160 to accommodate portable use. Bracelet 10 may be powered by a 2000 mAh, 7.4 V lithium polymer battery 160, to provide for at least one hour of therapeutic blood irradiation, and to also provide the body temperature regulation discussed hereinafter. Power may be provided at 1 hertz up to continuous. Other types of batteries can also be used. Management and budgeting of power from the battery 160 for each of the components is detailed in
The second treatment module 200 may have dual functionality, being configured to provide additional selective wavelengths of light specifically directed to vasculature of the wrist (i.e., the radial and ulnar arteries), and to provide body temperature regulation, when and if desired, control of which may be through a selected treatment protocol.

The second treatment module 200 may also broadly include a cooling device 260 that may be configured to draw away heat and thereby cool the first side 201 of the second treatment module 200. The cooling device 260 may be a cooling pack (i.e., a bag or pouch configured to separate water from ammonium nitrate, calcium ammonium nitrate, or urea, whereby agitating the bag/pouch causes mixing of the components to produce an endothermic reaction, and thus cooling), an ice pack, and/or a thermoelectric cooling unit (TEC). Note that use hereinafter of the term TEC within the specification in discussing the cooling provided by the bracelet is merely for convenience, and is not intended to limit the different forms that the cooling device may take. The spaced positioning of the first and second rows of light sources 210 to particularly direct light upon the radial and ulnar arteries may permit placement of the cooling unit 260 therebetween, which may be generally centered within the second treatment module 200. The TEC may be located on a daughter board, and not on the main board (PCB), and may be controlled by a microcontroller.
The second treatment module 200 may also broadly include a gasket 270 that may be positioned around the sides of the cooling unit 260, and may be thermally insulating to better ensure the directionality of the heat transfer (i.e., prevent leakage of heat around the sides of the cooling unit). Also, a plate 280 may be made of a thermally conductive material and may be positioned on at least a portion of the first side 201 of the second treatment module 200, to more effectively draw heat away from the wearer's wrist and towards the first side of the cooling unit 260. The thermally conductive plate 280, which may be H-shaped, may be positioned to overlie the cooling unit 240, as seen in the cross-sectional view of
A peel and stick disposable cushion similar to cushion 170 may also be releasably secured about the periphery of the first side of the second treatment module 200; however, it thereat serves a thermal function. The cushion on the second treatment module 200 may be made of a material that is thermally resistant (i.e., having a low coefficient of thermal conductance), and may serve to increase the efficiency of heat transfer between the wearer's wrist and the TEC, rather than with respect to the surrounding air, which may be prevented by the cushion from flowing over the unit due to movement of the user and his/her arm.
The connector band 300 for spaced coupling of the first treatment module 100 to the second treatment module 200, and the attachment band 400 for releasably/adjustable coupling of the first treatment module to the second treatment module for securement to the wearer's wrist, are shown in the exploded view of
The connector band 300 is shown in detail in
The attachment band 400 is shown in detail in
The first treatment module 100 of bracelet 10 may also broadly include an LCD screen, which may be a touch screen, and a microprocessor that may be coupled to the LCD screen, the cooling unit, and to the light sources. Firmware and/or software implemented therein may cause the display of one or more graphical user interface (GUI) screens on the LCD. Exemplary GUI screens are shown in
Additionally, or alternatively, a smart phone application may be used for remote controlling of each of the parameters that may otherwise be controlled by switches or the firmware controlled by the LCD screen that are physically located on the device itself.
In yet another embodiment, an IR pulse sensor may leverage use of a microprocessor. The IR pulse sensor and other sensors may derive pulse wave characteristics, for example, parameters such as Heart Rate (HR) and Heart Rate Variability (HRV).
In addition, the device may have an accessory port that that may be a charging USB port that can also provide a digital signal and can power via USB protocol, or other light or cooling accessories. For example, it could power an intranasal or intra-auricular LED probe. These accessories may be controlled by a smart phone application or may otherwise be controlled by switches or the firmware controlled by the LCD screen that are physically located on the device itself.
The device may also utilize two temperature sensors in the thermal module. One temperature sensor may be internal and may monitor the temperature of the TEC from a safety standpoint, and may provide feedback to the user via the app (i.e., may serve as a watchdog to ensure the TEC doesn't go out of the expected operating temperature range). The other sensor may be remotely mounted to touch the user's skin to monitor the skin temperature. It may be thermally isolated from the TEC and the thermally conductive material such that the only thermal influence will be the skin (i.e., plastic mounting features may be used). Both of the temperature readings may be reported back to, and monitored by, the user in near-real-time, if they are using the app (i.e., as test as Bluetooth can transmit and process essentially).
Tests of a prototype were conducted, to test a used for work volume capacity and strength gains, directly. In a warm environment, the test used lower-body large muscle exercises to raise core-body temperature and then tested the work capacity of upper-body large muscles. The independent variable was simultaneous wrist LLLT irradiation and arterio-venous blood cooling. The duration and total workload of lower body exercise was held constant. When work volume capacity gains increase, conditioning gains could also be expected. Frequent physical conditioning commonly leads to plateaus where minimal improvements in strength or work volume can be achieved over time.
During testing of the device, the subject demonstrated a 112% increase in pull-down capacity and a 43% increase in work volume. Strength gains were also measured by increases in the weight that could be bench-pressed only once in the fourth set of a pyramidal workout routine. An increase of over 11% in fourth set weight increases were observed in addition to a 33% increase in bench press work volume, leading to the conclusion that material performance gains were achieved from the use of a wrist-worn, portable device that interfaces only transcutaneously with arterial blood flow. An ARX machine was used to measure gains on both capacity and strength on both upper body exercises.
