Description
Technical Field
The invention belongs to the field of medical care, and particularly relates to a medical self-heating far infrared resonance wave paste with a central radiation wavelength of about 9.353 microns and a preparation method thereof.
Background
Infrared is an electromagnetic wave with a wavelength longer than that of visible light, and is one of many invisible lights in sunlight. In spectroscopy, infrared light is divided into near infrared (0.75-3 microns), mid infrared (3-40 microns) and far infrared (40-1000) micron bands. The infrared ray can generate heat effect and non-heat effect after irradiating the human body, and the heat effect is that molecules in the human body transfer energy in a collision or radiation mode under the action of the electromagnetic wave of the infrared ray and are converted into heat energy inside the human body. The non-thermal effect is a series of physiological effects generated by organisms on electromagnetic waves, including the participation of initiating free radicals and signal molecules, and is a non-linear response. These effects can cause vibration of water molecules inside and outside the cell, activating the cell, and producing a series of biochemical and histochemical changes beneficial to health of the cell.
A large number of clinical tests show that the far infrared has the effects of regulating autonomic nerves, protecting skin, beautifying, diminishing inflammation, easing pain, improving the circulatory system, enhancing metabolism, improving the immunologic function and the like, and the infrared phototherapy method is widely applied to the fields of treatment, health care, beautifying and the like. The infrared ray has strong penetrating power to skin and subcutaneous tissue of human body, and the infrared ray radiation can increase the temperature of skin and subcutaneous tissue, promote blood circulation and metabolism, diminish inflammation, promote regeneration, etc. After being irradiated by infrared rays, the blood flow speed of capillary vessels is accelerated, the phenomenon of erythrocyte aggregation is reduced, the phenomenon of blood stasis of subcapillary venous plexus is reduced or eliminated, the micro blood flow state can be obviously improved, and the infrared radiation type micro-organ treatment liquid has positive effects on nutrition, metabolism, repair and functions of important organs. The infrared ray acts on water molecules to strengthen the vibration of the water molecules, so that large molecular groups are cracked into smaller water molecule groups, the activity of calcium ions in cells is improved, the normal functions of the cells are enhanced, and the antibacterial and immune abilities of the human body are improved.
Medical research shows that low-temperature scald can be caused when a human body contacts an object with the temperature of more than 40 ℃ for a long time, particularly, the wound surface is often deep when the contact time is long, and even a plurality of patients with low-temperature scald can reach III-degree scald. The existing infrared therapeutic products mainly comprise an infrared therapeutic apparatus adopting an infrared lamp technology, a self-heating type hot application patch utilizing chemical reaction to release heat, an electric heating warmer, an electric blanket, a massager and the like, and the temperature generated by the products is higher than the temperature of a human body. Such as: the working stability of a typical infrared generator of the frequency spectrum therapeutic apparatus is usually 100-500 ℃; the temperature of the hot application is generally 40-60 ℃, and the average temperature is more than 50 ℃. These products raise the body's temperature by infrared radiation, which increases the evaporation of water from the epidermis, causing problems such as red pimples, premature skin aging and pigment disorders.
Human life can not be separated from far infrared rays, any object can generate heat radiation at a thermodynamic temperature above zero, and the human body can emit and absorb the far infrared rays at all times. According to kirchhoff's law, the greater the absorption ratio of a body to radiation, the stronger the radiation emitted. According to Stefan's law, the spectrum of thermal radiation is continuous and the wavelength distribution of radiation varies with temperature. Ideally, the total radiated power emitted by a black body (capable of fully absorbing the radiation it receives), including various wavelengths, is proportional to the 4 th power of the absolute temperature T of the black body. The distribution of the radiation exitance in terms of wavelength is a curve with a peak. Each temperature corresponds to a different peak wavelength and shifts to shorter wavelengths as the temperature increases.
According to Planck's formulaThe variation curve of the radiation exitance along with the wavelength and the peak value thereof under different temperatures can be accurately calculated.
According to Schrodinger theory, the standard body temperature of the human body is 36.67 ℃, and the maximum value of the radiation brightness of the emission spectrum of the human body is 9.353 mu m through calculation. When the wavelength of the irradiated far infrared ray is overlapped with the wavelength emitted by the human body and has the same far infrared radiation peak value, the far infrared ray resonance wave has resonance with cell molecules in the human body, and can play biological functions of activating cells, promoting blood circulation, accelerating metabolism, improving the immunity of the human body and the like to the maximum extent.
The phase-change heat storage material stores and utilizes heat by utilizing phase-change latent heat generated in the phase-change (such as solidification/melting, condensation/vaporization, solidification/sublimation and the like) process of a substance, and automatically releases or absorbs heat to the environment by utilizing the phase change of the material within a certain temperature range. When the ambient temperature is lower than the phase transition temperature, the material releases the stored heat to increase the ambient temperature; when the ambient temperature is higher than the phase transition temperature, the material absorbs and stores heat to reduce the ambient temperature, thereby achieving the purpose of controlling the ambient temperature.
