[0026] Embodiments of the present disclosure will now be described by way of example only and with reference to the following accompanying drawings. In the figures, the same reference numerals denote the same or similar elements.

[0027] Fig. 1 shows a perspective view of a device according to an embodiment of the present disclosure.

[0028] Fig. 2 shows a perspective view of a device according to an embodiment of the present disclosure.

[0029] Fig. 3 shows a top view of a device according to an embodiment of the present disclosure.

[0030] Fig. 4 shows a perspective view of a device according to an embodiment of the present disclosure.

[0031] Fig. 5 shows a perspective view of a device according to an embodiment of the present disclosure.

[0032] Fig. 6 shows water crystal images from water crystal experiments for gold-plated contact surfaces according to an embodiment of the present disclosure and for non-gold-plated contact surfaces (reference sample). With reference to Figs. 1 to 3, a device as disclosed herein comprises a housing 1, wherein an internal cavity is formed within the housing 1. The cavity is accessible via at least one opening 2, preferably at least two openings and more preferably exactly two openings. That is, the at least one opening 2 may communicate with the cavity. In the figures, two openings 2 are shown, but the present disclosure is not limited to this specific configuration. The opening 2 is configured to receive a body part which may be a limb such as a hand, an arm or a foot. In other words, a body part may be entered through the at least one opening 2 and received in the cavity. The housing 1 further comprises a temperature module (not shown) configured to provide heat or cold to the cavity, a light emitting module (not shown) configured to provide light to the cavity and a frequency generator (not shown) configured to provide electromagnetic radiation or sound / vibration to the cavity. As used herein, vibration encompasses sound, i.e., acoustic waves.

[0033] Sound may be generated by a vibration generator (frequency generator), conventional speaker or a resonance speaker. In particular, the sound may be transmitted as solid-borne sound. In an embodiment, the sound may be transmitted via the housing 1. By using a resonance speaker, the sound or vibration may be transferred to the housing 1 and thus transmitted. Thereby, broadband signals such as music or voice, narrow band signals or special vibrations may be transmitted. Since a user may place their hand(s) in the cavity and contact the cavity, i.e., the housing 1, sound waves may thus be transmitted to the user's body.

[0034] The sound waves may be audible or non-audible.

[0035] The frequency of the sound / vibration may be between 430 Hz and 440 Hz and preferably 432 Hz. A frequency of 432 Hz may aid a user in relaxation, lowering the pulse and lowering blood pressure.

[0036] The temperature module may be configured to provide a temperature between -4°C and 35°C, preferably between 0°C and 25°C, more preferably between 0°C and 20°C, more preferably between 4°C and 15°C, and more preferably between 4°C and 12°C inside the cavity. The temperature module may be an air conditioning device. Also, the temperature module may be provided in the cavity as contact surfaces on which a user places their hands. In particular, the temperature module may comprise contact surfaces / cooling elements 5 inside the cavity for cooling a user's palm (see Fig. 3). The cooling elements 5 may be convex such that a user may ergonomically place their hand(s) thereon without experiencing fatigue. The contact surfaces / cooling elements 5 may be formed as bumps.

[0037] This may lead to heat transport from the body part placed inside the cavity to the cooled ambient air and thus cool the body of an individual. In other words, thermal energy from the body core of the individual can be extracted.

[0038] A body temperature of an individual is normally controlled by controlled blood flow to particular skin areas, where subcutaneous vascular structures (venous plexus) are provided to deliver large volumes of blood adjacent the skin surface.

[0039] In particular, if it is desired to transfer heat from the body to the environment, the blood vessels expand (vasodilation) to increase the blood flow to said areas for transferring heat to the environment thus reducing the deep body core region temperature.

[0040] On the other hand, in colder environments, the blood vessels contract (vasoconstriction) to reduce blood flow and minimise heat loss to the environment.

[0041] In that manner, an internal body temperature is controlled for maintaining the organs within a functional temperature range. Since the heat transfer is performed via the skin, this process may additionally be sensitive to external stimuli such as heat or cold.

[0042] Vasodilation and vasoconstriction may also be pathological conditions that may be treated using temperature. The temperature treatment can find further use in a variety of applications, e.g., providing relief from temperature sensitive disorders, such as multiple sclerosis, and the treatment of hyperthermia. The device and method may further be suited for use in enhancing the physical ability of an individual.

[0043] The heat or cold treatment may be further enhanced by a low pressure module provided in the housing and configured to generate negative pressure inside the cavity. Using the low pressure module, i.e., by applying a negative pressure condition to the body part placed in the cavity, blood circulation may be controlled, and / or blood pressure may be controlled. In particular, the vasoconstriction temperature may be lowered and / or the vasodilation may be increased. The contact surfaces / cooling elements 5 may be gold-plated. This may further improve the effect of the disclosed device. The improved efficacy of gold-plated elements has been analysed using the methods of Masaru Emoto, in particular water crystal experiments and water crystal images (see Fig. 6). The experiments have shown the positive impact of the described device on the generation of water crystals (ice crystals).

[0044] Each opening 2 may comprises a sleeve configured to, when the body part is placed in the cavity, seal the cavity in a substantially air-tight manner. Thus, the negative pressure condition can be generated and maintained more effectively.

[0045] The light emitting module may be configured to generates visible light and / or non-visible light. That is, light of the visible spectrum or, e.g., infra-red light may be generated and provided inside the cavity. Infra-red light may be used for heat treatment while UV-light may be used for treatment of the skin.

[0046] The light emitting module may be a laser module. The wavelength of the laser light may be specifically adapted to the individual and used to treat pain. In that regard, general reference is made to literature concerning light therapy.

[0047] The light signal may be a broadband light signal or a narrow band light signal. For example, the light may be white light, a primary colour, or a mixture of primary colours.

[0048] The light emitting module may be configured to provide non-pulsed light, in particular nonpulsed LED light. Light emission may be continuous.

[0049] A skin resistance may be measured using an appropriate sensor to individually adapt the colour of the emitted light based on the user's skin resistance.

[0050] The colour frequencies may be determined or adapted by octaves and / or quints based on the number 1. The frequencies may be determined or adapted in steps of 1 Hz, preferably 0.1 Hz, more preferably 0.01 Hz.

[0051] The device may further comprise or be connected to a pulse monitor configured to monitor a user's pulse. The light frequency (LED frequency, colour frequency) may be determined or adapted based on the user's pulse. In particular, the frequency may be determined or adapted in steps of 1 Hz, preferably 0.1 Hz, more preferably 0.01 Hz. For further information, it is referred to www.aquaquinta.com providing background to the above-mentioned concept.

[0052] The device may further be configured to analyse a user's chakra(s). In particular, colour chakra(s) (colour light chakra(s)) may be considered. In case of one or more colour chakra(s) that are not properly supplied (undersupplied), only the relevant chakra or chakras will be supplied with light. In other words, a colour of the light emitted by the light emitting module may be adapted based on the chakra(s) and / or chakra supply. The frequency generator may be configured to provide electromagnetic radiation having a frequency between 10 and 100 Hz, preferably between 40 and 70 Hz. In this context, it is generally referred to literature concerning frequency therapy.

[0053] As noted above, the frequency generator may also be configured to generate sound / vibration. The sound may be in a frequency range of 430 Hz to 440 Hz, in particular 432 Hz. Further, the frequency generator may be configured to generate broadband signals such as voice and / or music.

[0054] The device may further comprise a processor. The processor may be configured to control at least one of the temperature modules, the light emitting module, the frequency generator, or the low pressure module.

[0055] The temperature module, the light emitting module and the frequency generator may be configured to operate iteratively or continuously.

[0056] The temperature module, the light emitting module and the frequency generator may be configured to operate simultaneously and / or consecutively.

[0057] The housing 1 may further comprise at least one temperature sensor (not shown) for sensing a temperature of the cavity and / orthe body part placed in the cavity. The temperature sensor may be a contactless temperature sensor. Moreover, the temperature sensor may transmit a measured temperature to the temperature module and / or a controller, allowing the temperature module to control the temperature inside the cavity accordingly.

[0058] Moreover, the housing 1 may comprise a pressure sensor (not shown) for sensing a pressure in the cavity and being in communication with the low pressure module and / or the controller. Further, the device may comprise an electrocardiogram (ECG) sensor to measure and analyse heartbeat rates. The heartbeat rate and / or a heart frequency graph may be output on the display described below and / or sent to a server and / or a mobile terminal.

[0059] In an embodiment, the ECG sensor may be included in the temperature module. That is, in case the temperature module is implemented as a contact temperature module, e.g., the cooling elements / contact surfaces 5 described above, ECG data may simultaneously be obtained using an integrated ECG sensor. In particular, the cooling elements / contact surfaces 5 may be used as an electrode since they are in contact with a user's palm.

[0060] In addition, or alternative to the ECG sensor, the device may comprise a pulse oximeter for monitoring a user's blood oxygen saturation. The data may be output via the display described below and / or sent to a server and / or a mobile terminal.

[0061] Further sensors for measuring further vital functions may also be provided.

[0062] The contact surfaces 5 may also be configured to detect touch movements or touch inputs / impulses by a user for controlling the device.

[0063] The present disclosure further relates to a corresponding method.

[0064] Fig. 1 shows a perspective view of a device according to an embodiment of the present disclosure. As described above, the device comprises a housing 1 and two openings 2. On an upper surface of the housing 1, a window 3 may be provided allowing a user to view the inside of the housing 1, i.e., the cavity. The housing 1 may further comprise handles and plug providing a wired connection.

[0065] Fig. 2 is a perspective view of a device according an embodiment of the present disclosure. As can be seen from the figure, the openings 2 may comprise sleeves which, when a body part is placed in the cavity, seal the cavity in a substantially air-tight manner.

[0066] Fig. 3 is a top view of the device according to an embodiment of the present disclosure. The internal cavity may be inspected via the optional window 3. The device may further comprise a display 4 and / or at least one control button. The display 4 and / or at least one button may be provided on a top surface as shown in the figure or a side surface of the housing 1. Figs. 4 is a perspective view of the device according to an embodiment of the present disclosure. The device generally corresponds to the device as described above, wherein the display 4 is not provided on a top surface of the housing 1 but protrudes from the housing in a generally upward direction. In particular, the display 4 may be moveably connected to the housing 1, e.g., via a hinge, such that its angle may be tilted from being substantially flush with the upper surface of the housing 4 to being tilted to an angle allowing a user to comfortably view the display 4. The angle range between the display 4 and the top surface of the housing, i.e., the window 3, may be between 0° and 180°. Thus, the display angle may be adapted according to a user's height.

[0067] In the closed / folded state (angle 0°), the display 4 may partially or fully cover the top surface of the housing. That is, the display 4 may have the same or a smaller area that the top surface of the housing 1.

[0068] In an embodiment, the display 4 area / size may be at least 50 % of the area of the top surface. In a further embodiment, the display 4 area may be 70 % of the area of the top surface.

[0069] Also, as shown in Fig. 5, the display 4 may have substantially the same size as the top surface (100 %). That is, in a closed state, the display 4 fully covers the top surface of the housing 1.

[0070] The display 4 area as used above encompasses the complete area of a screen and a frame or side panels, if present.

[0071] The display 4 may be used to control the device and / or display an operational state thereof. For example, the display 4 may be used for displaying safety instructions, user instructions, user guidance, status of a current treatment, vital data, graphics, general information, health condition, handling of payments, advertisement, etc.

[0072] The display 4 may be a touch display. Moreover, interface elements may be located adjacent to the display.

[0073] The top surface of the housing may be a glass surface.

[0074] The device may wirelessly or via a cable be coupled to a server and / or a mobile terminal. Data generated in the device may be processed and / or display at the server and / or mobile terminal.
