Since the summer vacation, no less than 3 friends have come to the clinic to inquire about edema after foreskin surgery. Many for-profit medical institutions have always recommended infrared bake lamps to treat postoperative edema and promote healing. Should this treatment be done? Let’s take a look at the information on the Internet. Many unfortunate victims are still doing such troublesome treatment. Are these institutions all fools? Let’s take a look at the description of infrared therapy devices~~ Philips may be the forerunner. Take a look at their introduction: Infrared therapy is a major breakthrough in global medical pain management. This technology uses infrared, especially near infrared (NIR, IR). -ADIN) can penetrate into the characteristics of human tissues and the effect of infrared heating, increase the temperature of the tissues, expand the capillaries, promote blood circulation, enhance material metabolism, and improve the vitality and regeneration of tissue cells. In the treatment of chronic inflammation, infrared rays can improve blood circulation, increase the phagocytic function of cells, eliminate swelling, and promote inflammation to dissipate. Infrared rays are often used to treat sprains, promote tissue swelling and hematomas to dissipate, reduce postoperative adhesions, promote scar softening, and reduce scar contracture. At present, the frequent incidence of neck and back pain has spread from the elderly and long-term manual laborers to young people and urban white-collar workers. Among outpatients in China, more than 30% come to see a doctor because of neck and back pain. Among them, the proportion of urban white-collar workers is increasing, mainly due to long-term high-pressure desk work. Cervical spondylosis is also a common and frequently-occurring disease, affecting a wide range of people. It can be affected from 21 to 83 years old, with a prevalence of more than 64.52%. Among the elderly, the pain caused by osteoarthritis accounts for the majority. The latest statistics show that nearly 70% of people over 65 have different degrees of osteoarthritis. Therefore, the baking lamp is not designed to reduce edema and wound healing after foreskin surgery. Muscle aches and joint diseases are its main treatment options. If it is too far-fetched to understand the application, it must be taken care of by a special person, so as not to get burnt. I also truthfully relayed these contents to my friend’s inquiry. Everything exists with its rationality, but it is not good if it is too far-fetched!
(1) Q-switched laser and picosecond laser technology: Q-switched laser refers to laser that is modulated by Q-switching technology and releases high-intensity energy density with extremely short pulse width (usually nanosecond). According to different wavelengths, there are currently four Q-switched lasers: frequency-doubled Q-switched Nd:YAG532mm laser, Q-switched ruby laser, Q-switched emerald laser, and Q-switched Nd:YAG1064mm laser. Due to the nanosecond pulse width, and these wavelengths of laser light can be better absorbed by melanin particles, these lasers become an excellent treatment for superficial and some melanin particles with even distribution of dermal pigment hyperplasia. (2) . Ultraviolet and excimer laser excimer laser (excimerlaser) is a pulsed gas laser, which is activated when the current passes, and releases a monochromatic light of a certain wavelength. The gas is a mixture of inert gas and halogen, and the activated inert gas and halogen can form a halide. Xe-Cl excimer laser 308nm is currently used in dermatology. The Xe-Cl dimer is composed of inert gas ??the outermost layer has 8 electrons and halogen chloride ??the outermost layer has 7 electrons. Halogen can be combined with other atoms by accepting an electron, and the excimer exists only in a bound state when the current is activated. (3) Permanent hair removal by hair removal laser requires destruction of the hair follicle stem cells and/or the dermal papilla at the base of the hair follicle base. These non-pigmented targets are far from the melanin group of the colored hair shaft. In order to damage non-pigmented targets, heat needs to be diffused from the pigmented parts to the surroundings. To achieve this effect, high-energy, millisecond pulses from the red to infrared wavelengths in the spectrum must be used to penetrate deep into the dermis and be selectively absorbed by melanin. Ruby, alexandrite, semiconductor and Nd:YAG lasers can all be used for hair removal. However, due to the lack of melanin pigment groups, these lasers are not effective for blond and white hair. (4) . Dye laser and other vascular treatment laser until the emergence of pulsed dye laser (PDL) technology, argon laser is the earliest treatment option for vascular disease. The correlation between 488 and 514mm wavelength argon laser and hemoglobin absorption spectrum is not very good, and can be strongly absorbed by melanin. This situation and the reality that they are continuous lasers can produce non-specific heating of surrounding tissues during treatment. As a result, the treatment has a high risk of scarring. Argon lasers are no longer routinely used in clinical work (5). Infrared lasers with long pulse width are one of many invisible lights in the sunlight spectrum. The wavelength of infrared light on the spectrum is greater than that of visible light, and the wavelength is 700m~1m. The International Commission on Illumination (CIE) recommends that the infrared region be divided into the following three parts: infrared A (R-A) wavelength 700 ~ 1400nm, infrared B (IR-B) wavelength 1400 ~ 3000nm, infrared C (RC) wavelength 300m ~ -1mm. Generally, users refer to the near-infrared (NIR) wavelength range from 750nm to 1400nm. Long-pulse-width infrared lasers used in skin laser medicine are mainly concentrated near the near-infrared band.
& nbsp. & nbsp. Summer is the season of high incidence of solar dermatosis. Many patients will think that they are allergic to ultraviolet rays, but not all are caused by allergies. At the same time, faced with a variety of sunscreen products have also fallen into “difficulty in selection”. Let’s first understand some common sense and then choose according to your own situation. & nbsp. & nbsp. & nbsp. According to the wavelength of sunlight, sunlight is divided into ultraviolet, visible, and infrared. Ultraviolet and infrared are invisible light and cannot be noticed by the naked eye, but can be recorded by the instrument. & nbsp. & nbsp. & nbsp. Ultraviolet: wavelength 180 ~ 400nm, is the main spectrum that causes skin diseases. & nbsp. & nbsp. Visible light: wavelength 400 ~ 760nm, after scattering, it is divided into 7 colors of red, orange, yellow, green, cyan, blue, and purple. & nbsp. & nbsp. Infrared: wavelength 760 ~ 1800nm. & nbsp. & nbsp. & nbsp. The solar radiation is mainly concentrated in the visible part (400 ~ 760nm), and the infrared part with a wavelength greater than visible light (& gt.760nm) and the ultraviolet part less than visible light (& lt.400nm) are few. Of all the radiant energy, the visible light region accounts for about 50% of the total solar radiation energy, the infrared region accounts for about 43%, and the ultraviolet region has very little solar radiation energy, accounting for only about 7% of the total. & nbsp. & nbsp. & nbsp. The main cause of skin diseases is ultraviolet rays. Ultraviolet rays are subdivided into short-wave ultraviolet rays, medium-wave ultraviolet rays, and long-wave ultraviolet rays. Among them, medium-wave ultraviolet rays and long-wave ultraviolet rays are the main action spectra that cause photosensitive skin diseases. The short-wave ultraviolet rays are all absorbed by the atmospheric ozone layer and cannot reach the surface of the earth. & nbsp. & nbsp. & nbsp. The longer the ultraviolet light wave, the stronger the penetration and the less energy. & nbsp. & nbsp. UVB can only reach the basal layer of epidermis, and intense exposure can cause epidermal necrosis and pigmentation. & nbsp. & nbsp. Long-wave ultraviolet rays can penetrate the epidermis and act on the superficial layers of the dermis, causing skin aging. & nbsp. & nbsp. Common solar skin diseases include solar dermatitis, solar urticaria, multi-type solar rash, photokeratosis, photoaging, etc. & nbsp. & nbsp. Sunburn refers to acute skin inflammation caused by the skin receiving medium-wave ultraviolet rays that exceed the tolerated amount, mostly caused by excessive sun exposure, which is an acute phototoxic reaction. And long-term repeated sun exposure will cause photokeratosis and photoaging. & nbsp. & nbsp. It should be noted that some photosensitizers can increase the risk of disease, such as Chinese cabbage, fennel, shepherd’s purse, celery, rapeseed, mustard, mango, lemon, fig, snail, crab, etc.
