DESCRIPTION

T-shirt for measuring internal / external temperature, sweating and ultraviolet radiation. Object of the invention

The present invention relates to an article of clothing, type T-shirt, made of hypoallergenic material, preferably of a light color that incorporates sensors for the measurement of body temperature, external temperature, sweating sensor and ultraviolet light.

Field of application of the invention

The article of this invention, called t-shirt for the measurement of internal / external temperature and ultraviolet radiation, is applicable in the sector of physical activity, sports and health, as it allows to predict and prevent the risk of suffering from increased dehydration of body temperature and burns caused by ultraviolet rays emitted by the sun.

Background of the invention

The incidence of skin cancer grows significantly worldwide. Exposure to ultraviolet (UV) radiation from the sun or artificial sources is the main preventable cause of skin cancer [1]. Sunburns are a determining factor in the risk of skin cancer and more and more people suffer from them during the practice of outdoor physical activity.

Exposure to ultraviolet radiation can be reduced through preventive strategies that include scheduling work tasks outside UV peak hours (11 am - 4 pm), shade protection, wearing hats or caps, shirts and sleeve pants Long, sunglasses and sun creams.

Various epidemiological studies have highlighted the high solar radiation that different groups of athletes receive through personal dosimetry [10] [3] and their poor adherence to recommendations on photoprotection (schedule, shade, clothing, hat, sunglasses and creams) To the lack of awareness, the lack of shadows of the sports facilities, the schedules of the training and of the sports competitions, the contact with the water in the water sports and the height or the snow in the mountain sports are joined. In general, athletes have poor photoprotection practices, high rates of sunburn and other skin damage related to sun damage [6] [4].

On the other hand, an excessive increase in body temperature, caused by excessive physical exercise and a poor ability to regulate temperature, can lead to episodes of dehydration and increase the risk of heat stroke or thermal shock, one of the most severe cases of hyperthermia. This situation, which can be fatal, occurs when the body temperature exceeds 40 ° C and the body is not able, through hypothalamic adjustment, to regulate the temperature.

The union of exposure to ultraviolet rays with a high body temperature can increase the risks of skin cancer, as seen in the latest research. For example, in the study "Infrared radiation increases skin damage induced by other wavelengths in solar urticaria" by Gálvez MV et al. they suggest how infrared (IR) radiation, related to the rise in temperature, has the potential to produce and exacerbate lesions caused by other types of radiation, such as ultraviolet radiation [5].

State of the art

There are many types of shirts aimed only as garments and others that integrate devices for physiological control, as an example:

T-shirt with reinforcement ES0209116U: T-shirt with the objective of reducing the perimeter of the waist and also makes it possible to reinforce said area in case of injury

T-shirt with sleeves sweatshirts for sports 0200500486: The invention relates to a shirt for sports in general and especially tennis and paddle, which has the particularity that its sleeves are made of a sweat-absorbent textile material.

Garment formonitoring physiological properties US8340740B2: Allows monitoring of a person's heart rate by means of electrodes arranged on the back of the shirt. The information can be displayed on the same garment or by remote broadcast on other devices.

Monitoring patient using intelligent t-shirts US9330558B2: Textile system that allows the incorporation of sensors such as accelerometers, gyroscopes, magnetometers, barometers, temperature, etc. In addition, it describes the use of solar cells to charge devices and to accumulate the kinetic energy of the subject when traveling or the body's own energy. Neither its objectives nor the description of the report describes the calculation of the internal / external temperature difference and its relationship with sports activity and possible dehydration. Nor does it mention the use of ultraviolet sensors or sweating in this development.

Apparatus, systems and methods for optimizing and masking compression in a biosensing garment W02016 / 134484 Al: It consists of a shirt made of different fabrics and structures allows different areas of variable compression on the body to accommodate different sensors for measuring parameters such as electromyography, heart rate, respiratory, temperature, etc. However, there is no mention of internal / external temperature measurement parameters, nor ultraviolet measurement, which should be positioned outside the shirt, not inside.

Conformal electronics integrated with apparel US 9082025B2: A system is described that similar to the previous one allows to monitor physiological parameters useful for the athlete and that, however, mentions Uv radiation values and temperature, among other infinity of sensors and devices integrated in all parts of the body, does not mention the use of the level of dehydration due to internal / external temperature difference or the use of biosensor or level of sweating.

Apparel having multiple alternative sensors and corresponding method US6930608B2: Development that, like the previous one, allows to position several types of sensor, heart rate, respiratory, magnetic, temperature and even ultrasonic temperature and its data can be sent wirelessly to a receiver. Like the previous development, it does not specify or describe the measurement of the internal / external temperature difference as a dehydration factor nor the use of biosensor for ultraviolet measurement and its relation to temperature.

"Coldblack" T-shirts and fabrics US9330558B2: Fabrics made with materials with properties to reflect UV rays and that, depending on the color, absorb one type or another of lightning so they allow greater heat control. However, they do not have associated technology to quantify the temperature and UV radiation.

Wearable digital device for personal health use for saliva, urine, and blood testing and mobile wrist watch powered by user body US2019206538A1: Refers to a personal health control system, comprising a system for measuring body and environmental parameters, among others , allows to calculate body temperature, ambient temperature and ultraviolet radiation received by the user. The system features body and environmental temperature sensors, a UV radiation measurement system and an information emission system by means of a wireless mobile phone system or similar. The differences with the device proposed herein are that it does not describe the placement of the different elements of the system in a shirt, which, moreover, can be made of a hypoallergenic material or the use of a sweating sensor.

Process and device for body climate control US2005197684A1: Refers to a garment specially designed as a vest with ventilation channels that are connected at its entrance and exit with the environment. Specifically, the system has a body temperature sensor, outdoor temperature sensor and a humidity sensor. The difference with the device of the starting documentation is that it does not describe a UV radiation measurement system, nor a system for issuing information by means of a wireless system to a mobile phone or the like.

Conformal electronics integrated with apparel US2014097944A1: Describes a system that allows monitoring physiological parameters useful for the athlete through sensors and devices integrated into body parts. Specifically, the system features a body temperature sensor, a UV radiation measurement system and a wireless communication system. The difference with the device of the starting documentation is that it does not present an ambient temperature sensor and therefore does not present information on the difference between the ambient and body temperature. Nor does it have a sweating sensor.

Apparel having multiple alternative sensors and corresponding method US2003214408A1: Describes a system that allows monitoring of a person's physical parameters through sensors and devices integrated into body parts. Specifically, the system features a body temperature sensor, a UV radiation measurement system and a wireless information emission system. The difference with the memory device presented here is that it does not have an ambient temperature sensor and therefore does not present information on the difference between the ambient and body temperature. Nor does it have a sweating sensor.

Thus, a garment that integrates all sensors is not known; UV, UV biosensor, internal temperature, external temperature and sweating. Nor are garments known to compare internal / external temperature or the ability to control the subject's body temperature with UV radiation and sweating. It is necessary to take into account that the correct location of these sensors and the relationship between the physiological variables that quantify all these sensors, are determinants for a correct measurement of the risk of sunburn and dehydration processes. Thus, the applicant of the present invention is unaware of the existence of a background that satisfactorily solves the problem presented.

The use of a shirt that reports the level of UV and IR (temperature) and prevents sunburn can be a useful system for the prevention of skin cancer.

On the other hand, that the subject has information on the difference between internal body temperature / external body temperature and sweating level, integrated in the shirt itself, can give you information about your ability to regulate body temperature, the level of risk of suffering a heat stroke and the strategies to follow for a correct hydration.

The present invention consists of a garment that is capable of:

- Know the ability to regulate the subject's body temperature by using two temperature sensors, one facing inwards of the garment and located in the axillary area and another oriented towards the outside of the garment and located in the left pectoral area.

- Know, through the use of a UV sensor, the risk of sunburn and UV index. Said sensor can be electronic type or biosensor type.

- Know the level of sweating of the subject, for the prevention of dehydration levels.

- Obtain, through the use of a shirt, which can be long or short sleeve, greater protection against infrared rays reflecting its incidence in the body.

The article of dressing with detectors of temperature, sweating and UV, object of this invention, presents some technical peculiarities intended to provide information to the user about the risk of sunburn or dehydration, in addition to serving as protection against it.

The shirt incorporates two temperature sensors located on the garment that allows quantifying the body temperature - being in contact with the subject's skin - and the external temperature, by means of a sensor located on the outer surface of the garment.

In addition, it is able to quantify the temperature associated with the infrared radiation that is received and the level of axillary sweating it produces.

A signal emission system will allow the data to be sent to the mobile phone, tablet or similar (12).

Preferred Embodiment of the Invention

The article made with hypoallergenic, breathable and preferably light colored fabric has as a particular feature the availability of three zones that allow the UV, sweat and temperature measurement sensors to be accommodated, which will be connected to a system Power supply by means of a button battery or similar and a data transmission system, via Bluetooth or similar, to the mobile phone or any other system that processes the received signal and informs the user.

Components:

Temperature sensors (TEM). The system has an encapsulated temperature sensor located at the left axillary level (TEM-axi), a sanitary reference point for measuring body temperature since it quantifies the temperature of the axillary artery (Figure 1-1). Other measurement points, such as rectal, sublingual or tympanic temperature would be impractical, uncomfortable for the user and complicate the construction of the shirt. It will be flat and small enough to go unnoticed and not hinder shoulder movements during physical activity. Similarly, this sensor is encapsulated to protect it from sweat and moisture. The axillary temperature sensor will be in contact with the individual's skin, enabling the actual measurement of body temperature.

The second temperature sensor will be located in the left pectoral zone, and will allow quantifying the external ambient temperature (TEM-ext) (Figure 2-7). For this, the sensor will be oriented outwards, external to the fabric of the shirt through a small eyelet or hole made in it. In addition, it will be isolated by a multi-layer temperature insulating fabric system originated by the subject himself. This insulating fabric can be textured fiberglass, aluminum film, acrylic or the like (Figure 2-12). The location of this sensor in this body area is crucial to capture the ambient temperature close to the subject, in a comfortable area that does not impede or hinder the mobility of the shoulder or trunk in the performance of physical activities. On the other hand, its proximity to the axillary temperature sensor (TEM-axi) allows to precisely quantify the difference in body temperature and external temperature; thus measuring the ability to regulate the subject's body temperature.

Both temperature sensors, TEM-axi and TEM-ext will be connected by flexible conductive wire (Figure 1-3), and housed in the fabric so that they can be removed at the time of washing the shirt.

Sweating sensor (LDS): The amount of water and electrolytes (mainly sodium) lost as a result of thermoregulatory sweating during exercise can vary considerably between people and also be conditioned by the outside temperature, external humidity level, ability to heat acclimatization, genetic predisposition, body size and composition, gender, diet and hydration status. Therefore, its measurement is decisive. The proposed system for its measurement is through the use of a flexible type sensor that located in the pectoral area and in contact with the skin, allows to quantify the level of sweating (Figure 1-14).

Ultraviolet (UV) sensor. The shirt will have a UV sensor located next to the outdoor temperature sensor (TEM-ext) in such a way that, at the same level - left pectoral area-, collect information about the ultraviolet light that affects the user (Figure 2-6) . This ultraviolet light sensor employs a photodiode that can detect light in the range of 200 370 nm (which covers the UVB spectrum and most UVA). The photodiode output incorporates an operational amplifier to raise the signal to manageable voltage levels. This sensor is used to detect the intensity of UV light, such as that coming from the sun. It will be configured according to the classification standard of the UV Index of the World Health Organization. This sensor will be water resistant to prevent deterioration if it is used in an aquatic environment.

The shirt also has a receptacle to incorporate an ultraviolet biosensor which will be attached to the shirt through the use of a compartment that allows ultraviolet light to pass, but at the same time allows the device to be held in front of the movements of the subject; especially during sports activities (Figure 1-13). The location of the biosensor in this body zone is determined by being a reference area in scientific publications to measure the UV radiation our body receives, as well as not hindering or hindering body movement.

LED lights / acoustic warning. LED lights (red and green) and an acoustic emitter will notify the subject when the time during which they have been exposed to UV radiation levels or body temperature is at dangerous levels and sun protection or protection measures have to be taken. hydration (Figure 2-9).

Power supply. A power supply, by means of a button cell, will provide power to the sensors, the signal emission system and the LED lights. Its location will be the same receptacle where it is located in UV sensor, sweating and TEM-ext (Figure 2-10).

Cabling. The infrared, sweating and ultraviolet sensors will be connected by flexible and heat-sealed electrical cable to the power supply.

Data acquisition and delivery system. Through it, the data will be sent via bluetooth or similar to a mobile phone or other signal receiver where the individual can check the body temperature, external temperature, body temperature regulation capacity and UV radiation. The ability to regulate body temperature will be quantified as a result of the difference in body temperature and external temperature.

T-shirt: The t-shirt, which may be short-sleeved or long-sleeved, where the different sensors will be incorporated, will be made of synthetic material (lycra or similar), natural (cotton or similar) or a mixture of various materials, which conforms to the body of the subject in such a way that the different electronic components do not move during movement (Figure 1). In the axillary area, where the internal temperature sensor is incorporated, it will have a band of elastic material to hold said sensor by means of a clip, hook or similar. In the left pectoral area, where the UV, sweating and TEM-ext system is located, a layer of insulating material is sewn or glued on the shirt, so that the temperature sensor only captures outside temperature, not interior temperature. A small hole made in the same shirt allows the wiring of the axillary temperature sensor to the central unit where the TEM-ext sensor, sweating sensor, UV sensor, signal acquisition and sending system, LED warning lights are located of danger or risk situation and input of optional sensors.

The shirt may optionally incorporate other sensors such as sensors to quantify levels of glucose and pH present in sweat. Blood glucose levels are important to quantify blood glucose related to the health status of the subject and its use is possible for the diagnosis of diabetes. In addition, pH provides more important information about health conditions. For example, skin diseases, such as dermatitis and fungal infections, can cause a pH change in sweat [8] [2]. Therefore, measuring glucose concentration and sweat pH can provide an important assessment to determine individual health conditions [9].

In a preferred embodiment, all the sensors and the data acquisition and sending card will be held by elastic fabric sewn to the shirt itself, clip system or the like, avoiding so that it moves or detaches itself, but that, on the other hand, allows it to be extracted to be able to proceed to wash it.

Similarly, another preferred embodiment will allow the data recorded by the sensors to be sent via cable or wirelessly to a screen located on the wrist of the individual so that, as a clock, you can have easier access to information (Figure 1).

In the prior art, none of the devices mentions the measurement of the difference in body / exterior temperature, measurement of the degree of humidity produced by sweating and the relationship with the ultraviolet index.

Once the nature of the invention has been sufficiently described, as well as an example of a preferred embodiment, it is stated to the appropriate effects that the materials, shape, size and arrangement of the described elements may be modified, provided that this does not imply an alteration of the essential features of the invention that are claimed below.
