(23) Types of Infrared Rays

(24) Infrared rays are divided into near infrared rays, mid infrared rays and far infrared rays depending on the wavelength.

(25) The human skin consists of stratum corneum, epidermis, dermis, subcutaneous fat and muscle. A depth of 4 mm or more from the skin is called subcutaneous fat, and the thickness of the subcutaneous fat is about 2 mm.

(26) In the present invention, the user's core body temperature can be increased by elevating the temperature most effectively and in a short time through heating of the subcutaneous fat layer.

(27) The near-infrared wavelength of 700 nm to 1,200 nm used in the present invention can penetrate more than 5 mm deep into the skin and heat the human body.

(28) The near-infrared wavelength is a direct heat transfer method that does not require separate preheating time as the light energy instantaneously generates 2,200? C. within 10 seconds rather than the existing thermal convection method, delivering heat energy with a thermal efficiency of over 90%.

(29) The world-famous scientific journal Nature published in 2006 that near-infrared rays have been shown to have over 1,000 effects in plant growth and human treatment experiments conducted by NASA (National Aeronautics and Space Administration) for a long time. In a published NASA paper, it was claimed that among the lights coming from the sun, only near-infrared rays have cell activation and biological healing effects, so they are the light of life that cures all diseases even though it is not applied or eaten. Since then, as a result of research by many medical institutions and scientists, the range of near-infrared rays has been discovered to have numerous different efficacies in each region within the range of 700 nm to 1,200 nm, and has been called the miracle light. It is also called a miraculous light because there are no side effects no matter how much it is used.

(30) For a tumor such as cancer, the wavelength needs to be adjusted to achieve the deepest penetration. The optimal near-infrared region that penetrates more than 5 mm into the skin is 850 nm or 1,200 nm. The wavelengths between these two regions most efficiently penetrate deep into the skin and increase the body's core temperature. Therefore, in one embodiment of the present invention, the near-infrared region generated from the LED and the wavelength of 700 nm to 1, 200 nm in the skin depth region of 5 mm or more are used.

(31) FIG. 2 is a perspective view of a whole body thermotherapy device according to an embodiment of the present invention.

(32) The term chamber used in the present invention is defined as a cylindrical container with a space for near-infrared treatment. The chamber consists of an upper plate and a lower plate.

(88) Method for Measuring Core Body Temperature

(89) 1. Core body temperature refers to the temperature inside the body. The core body temperature of the human body is around 37? C., the average temperature is 34-35? C. on the skin surface, and in the peripheral parts of the extremities, the temperature may drop considerably below the environmental temperature. The body temperature of healthy adults is around 36.5? C., but the body temperature is slightly lower in the elderly and slightly higher in infants (Source: Asan Medical Center, Seoul).

(90) 2. Core body temperature refers to the temperature of internal organs of the body, such as the heart or bladder, which is distinct from the peripheral part temperature of the extremities. Because the anesthesia administered during surgery may inhibit the ability to regulate the core body temperature, it is desirable to repeatedly check the core body temperature. Core body temperature can be measured with the US 3M? Bair Hugger Control Unit.

(91) 3. In the present invention, core body temperature refers to the body temperature of the user's head, chest and abdomen. In order to monitor and maintain the core body temperature in various clinical settings, an accurate measurement method focusing on non-invasive way is needed. The Tcore temperature monitoring system developed by German company Dr?ger is a safe and accurate non-invasive way. In one embodiment of the present invention, the Tcore temperature monitor can be attached to the user's forehead and measure the core body temperature.

(92) 4. By using the gSKIN? CBT sensor developed by GreenTEG in Switzerland, it is possible to accurately measure the core temperature on the skin without penetrating into the body. The gSKIN? CBT sensor is ultra-small at 2 mm?2 mm, can be easily applied to watch-type wearable devices, and can measure the core temperature in real time without significant impact on daily life.

(93) 5. In one embodiment of the present invention, after turning ON the power of the lower plate LED power source unit 113 and the upper plate LED power source unit 114, the surface temperature of the PC board, the temperature at the bottom of the PC board and the temperature inside the chamber were measured through a temperature sensor installed inside the chamber over time (minutes).

(94) The core body temperature was calculated and determined using the following calculation formula that may calculate the core body temperature using the measured temperature data. TB represents the core body temperature, and T1, T2, and T3 represent the PC board surface temperature, the PC board bottom temperature, and chamber internal temperature in the chamber shown in FIG. 2, respectively.

(95) The user's core body temperature TB is calculated and measured based on the condition values described above under the following assumptions.

(96) Assumption 1: Heat flows only in the vertical direction and thermal conditions in the measurement area are assumed to be constant.

(97) Assumption 2: Looking at Fourier's law of heat conduction from an electrical perspective, the thermal conductivity, thickness and area of the heat-conducting material are considered resistance to heat flow.

(98) Therefore, Fourier's heat conduction equation can be expressed as Equation 1 as follows.

(100) The PC board surface temperature T1, PC board bottom temperature T2, and chamber internal temperature T3 are measured as shown in Table 1. It can be expressed as the following equations 2 and 3.

(101) $\begin{array}{cc}{q}_{\mathrm{left}}=\frac{T_B-T_1}{R_s}=\frac{T_1-T_2}{R_1}=\frac{T_2-T_A}{R_A}& \mathrm{Equation}2\end{array}$$\begin{array}{cc}{q}_{\mathrm{right}}=\frac{T_B-T_3}{R_s+R_2}=\frac{T_3-T_A}{R_A}& \mathrm{Equation}3\end{array}$

(102) Here, the meanings of the condition values TB, T1, T2, and T3 are as described above.

(103) Therefore, by solving the simultaneous equations of Equation 2 and Equation 3, Equation 4 and Equation 5, which determine the core body temperature TB using the condition values T1, T2, T3, and TA, are as follows.

(104) $\begin{array}{cc}{T}_B=T_3+\frac{\left(T_1-T_2\right)\left(T_3-T_A\right)}{K\left(T_2-T_A\right)}& \mathrm{Equation}4\end{array}$$\begin{array}{cc}K=\frac{R1}{R_2+R_S}& \mathrm{Equation}5\end{array}$

(105) The core body temperature is calculated and measured using the above-mentioned equations using the K value which is the temperature estimation correction coefficient.

(134) The operation of the LED infrared irradiator according to one embodiment of the present invention proceeds in the following order.

(135) After turning on the chamber power (S10), the far-infrared heating element (S20) is turned on. It is determined whether the temperature is above 36? C. and the humidity is below 50% inside the chamber (S30).

(136) If the temperature is not above 36? C. or the humidity is not below 50%, the far-infrared heating element power is continuously kept ON (S20). If the temperature is above 36? C. and the humidity is below 50%, the far-infrared heating element is turned off (S40).

(137) Next, the near-infrared LED power is turned on (S50). Thereafter, it is determined whether the core body temperature is above 40? C. (S60). If the core body temperature is not above 40? C., it is determined whether the set time has elapsed (S61). If the set time has not elapsed, the near-infrared LED power is kept ON (S50). If the set time has elapsed, the near-infrared LED power is turned off (S62) and the chamber power is turned off (S80).

(138) If the core body temperature is above 40? C., the near-infrared LED power is turned off (S70), and then it is determined whether the set time has elapsed (S71). If the set time has not elapsed, it is determined whether the core body temperature is above 40? C. (S60). If the set time has passed, the chamber power is turned off (S80).
