DESC:TECHNICAL FIELD
[0001] The present disclosure relates to therapeutic devices. More particularly, the invention relates to a device for controlling menopausal hot flashes.

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] During the menopausal transition, the ovaries begin to work less effectively, and the production of hormones like estrogen and progesterone declines over time. Such changes can cause aberrations in the body’s thermal regulation mechanism leading to hot flashes and other menopausal symptoms. Hot flashes are sudden increases in body temperature and are perceived as intense increases in body temperature that are characteristically manifested by nearly instant occurrence of any one or a combination of flushing, sweating, dizziness, nausea, palpitations, and diaphoresis. The hot flashes can disrupt sleep, interfere with mental concentration and adversely affect the quality of life. The hot flashes are characterized by a sensation of intense warmth in upper body, followed by skin redness (flushing) and perspiration. Typically, these symptoms begin in the head and spread down towards the neck and chest. The hot flashes occur with varying frequencies ranging from a few flashes per week to several flashes an hour, some hot flashes pass after a few seconds, while a few last for more than 10 minutes. On average, hot flashes last for around 4 minutes but can be debilitating until their passage and during a complete recovery period that can last up to 30 minutes.
[0004] Moreover, the hot flashes are the most common symptom of menopause and perimenopause. They also affect women who start menopause after chemotherapy or surgery to remove their ovaries. In general, approximately 2 in 10 women never get hot flashes. Others have hot flashes for only a very short period of time. Still, others may have them for 11 years or more. On average, however, women get hot flashes or night sweats for about 7 years.
[0005] Existing treatment includes hormone replacement therapy (HRT), natural Food and preventive solutions, medicines, and many others. However, women are reluctant to undertake the HRT because a number of clinical trials have indicated a significant correlation between HRT and an increased incidence of heart disease, stroke, blood clots, and breast cancer. For this reason, many women have shunned HRT, leaving them with few effective alternatives for treating or controlling their hot flashes. Also, some women started taking natural food and preventive solutions, however efficacy not proven due to absence of scientific research. In addition, women have been prescribed medicines for controlling their hot flashes. However, multiple side effects of the medicines are detected, such as nausea, difficulty in sleeping, drowsiness, weight gain, dry mouth, sexual dysfunction, or the like. Thus, none of the existing solutions is found effective and safe.
[0006] There is, therefore, a need in the art to provide an efficient solution that can obviate the abovementioned limitations, and provides a device for controlling hot flashes by avoiding undesired and dangerous side effects of all known treatments.

DETAILED DESCRIPTION
[0041] The following is a detailed description of embodiments of the disclosure depicted in the accompanying drawings. The embodiments are in such details as to clearly communicate the disclosure. However, the amount of detail offered is not intended to limit the anticipated variations of embodiments; on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the present disclosures as defined by the appended claims.
[0042] Embodiments explained herein relate to therapeutic devices. In particular, the invention relates to a device for controlling menopausal hot flashes. More particularly, the present disclosure provides a device for cooling a wrist area of a user to control menopausal hot flashes. As known, menopausal hot flashes occur due to malfunctioning of the thermal regulation mechanism of the body due to hormonal imbalances caused by menopause. In event of even a slight increase in core body temperature, the body keeps thinking it is overheating and tries to cool down by sweating and flushing and blood rushes to the skin to help shed heat. In an aspect, the disclosed device for controlling menopausal hot flashes works along the same thermoregulation principle by cooling blood flow in that it cools down blood to control the menopausal flashes, thereby obviating any need for HRT or any other medication.
[0043] As is well known, wrist is one of the key points for heat dissipation. During exercise blood flow through the wrist increases by four times, and the inner side of the wrist dissipates five times as much heat as any other part of the body. Therefore, cooling directly on the wrist removes heat faster and reduces sweating almost immediately, provides cooling to the entire body and an instant comfort. Therefore, accelerating heat dissipation at the wrist by cooling is an efficient way to cool the entire body.
[0044] The present disclosure, by providing a cooling device that can be worn at wrist, makes use of above characteristics of wrist to efficiently and quickly bring down core body temperature during occurrence of hot flashes, Blood flowing through the wrist cooled by the device flows back to the core, reducing core temperature and eliminating the need for hot flashes by the body and providing instant relief..
[0045] In an embodiment, the device can include a housing adapted to be worn on the wrist, and the housing can include a cooling unit. In addition, the cooling unit can be configured to facilitate cooling the wrist, upon actuation of the device.
[0046] Referring to FIG. 1, a device 100 for controlling menopausal hot flashes is disclosed. The device 100 can include a housing 102 to be worn on a wrist of a user like a smart watch strap, band, or the like. The housing 102 can include cooling unit 104 for cooling the wrist, an actuator 106 for turning ON and OFF the device 100, and a processing unit 108 for controlling the device 100.

[0056] In an embodiment, the cooling unit 104 can be configured on the device 100 such that, when the device 100 is worn by the user, the cold conducting plate of the TEC 302 is in contact with wrist of the user to provide cooling effect to the user. In an embodiment, the device 100 can be worn by the user such that the cold conducting plate is on an inner side of the wrist, which dissipates body heat more efficiently.
[0057] In an embodiment, an actuator 106 can be coupled to the top layer 202 of the housing 102 using the adhesive, for example, silicon adhesive or the like. The actuator 106 can be a push-button that enables the user to apply slight force on the actuator, to control the device 100. The actuator can be coupled to the cooling unit 104 through the processing unit 108 for controlling level of cooling provided by the device 100. For example, successive pressing of the actuator 106 can change the level of cooling from a low level to a medium level and to a high level of cooling, besides putting the device ON and OFF.

Examples of such components include, but are not limited to, processing engine(s) and database. A database can include data that is either stored or generated as a result of functionalities implemented by any of the components of the processors(s).
[0060] In an embodiment, a power supply unit 110 can be coupled to the housing 102 to supply power to the cooling unit 104, the actuator 106, and the processing unit 108. Further, the power source can include any or a combination of rechargeable battery, lithium (Li) ion cell, rechargeable cells, electrochemical cells, storage battery, and secondary cell. In an exemplary embodiment, the battery can be a 3.7V Rechargeable Lithium Polymer that can consume power 5 watts maximum, approximately.
[0061] In an embodiment, upon actuation of the actuator 106, the power supply unit 110 can supply power to the device 100 to activate the device 100, further, the cooling unit 100 can be activated to provide cooling to the wrist of the user. Upon activation, the cooling unit 104 operates according to the Peltier effect. The effect creates a temperature difference by transferring heat between two electrical junctions, and a voltage is applied across joined conductors to create an electric current. When the current flows through the junctions of the two conductors, heat is removed at one junction and cooling occurs. The heat is deposited at the other junction. In addition, the fan 104A can be configured to blow air to cool the cooling TEC 302 faster. In an exemplary embodiment, the cooling occurs when a current passes through one or more pairs of elements from n to p type, thus decreasing temperature at the cold side resulting in absorption of heat from the environment. The heat is carried along with the elements by electron transport and released on the hot side as the electrons move from a high to a low energy state. Thus providing a cooling effect on the wrist to the user, and due to heat dissipation at the wrist, the entire body can be cooled automatically.

As shown therein, the TEC cooler 302 includes an array of semiconductor devices comprising a plurality of n-type semiconductors 316 and p-type semiconductors 314 arranged thermally parallel and electrically in series between a hot conducting plate 310-2 and the cold conducting plate 310-1. hot conducting plate 310-2 and the cold conducting plate 310-1 can be made of electrically insulating and thermally conducting material, such as ceramic material. The n-type semiconductors 316 and p-type semiconductors 314 can be electrically coupled to a battery by copper plated 308 and wires 318. The heat sink 304 can be thermally coupled to the hot plate 310-2.
[0063] In an embodiment, the cold conducting plate can be sized to have a surface area in a range of 3.0 sq cm to 20.0 sq cm such that when the device 100 is put on wrist, an area of the wrist in a range of 3.0 sq cm to 20.0 sq cm is cooled.
