Are there many dangers of laser therapy devices?

It has to be said that laser technology is a great invention. Laser communications, laser weapons, laser distance measurement, etc. are all achieved through lasers. Lasers are also widely used in medicine. They can be used as scalpels and laser scanners, etc. Laser therapy devices are also medical devices that use lasers. Laser therapy devices irradiate the human body with lasers and have therapeutic effects on cardiovascular and cerebrovascular diseases, diabetes, leukemia and even mental illnesses, but do you know what its dangers are?

The main damage caused by laser to the human body is to the eyes, followed by the skin.

(1) Damage to eyes and vision: Lasers can burn biological tissues, especially the retina. Because the laser beam can be focused into a very small spot on the retina through the eye's own refractive system, the light energy is highly concentrated and causes burns. Laser radiation in the infrared or microwave regions can be absorbed by the iris or lens and cause thermal damage, leading to iritis and cataracts. The damage of laser to eyes is related to factors such as wavelength, pulse width, interval time, beam energy, incident angle, and characteristics of irradiated tissue. When the glasses are exposed to laser, there may be a sudden sense of glare, blurred vision, fixed black shadows in front of the eyes, or even loss of vision.

The damage caused by laser radiation to the retina is painless and easily overlooked. Due to long-term and frequent exposure to small doses and diffusely reflected laser radiation, workers generally do not notice any damage to their vision. Sometimes they experience general neurasthenia, visual fatigue, eye pain, etc. after work, but there are no specific symptoms. Accidental laser damage to the eyes, except for some people who suffer permanent vision loss, most people recover to varying degrees after treatment.

(2) Damage to the skin Laser damage to the skin manifests as mild erythema, burning and even carbonization and necrosis of tissue. In addition, it can also damage pigment cells and cause capillary embolism. Sometimes blood vessel rupture and bleeding can be seen. Skin damage is usually reversible and reversible. The most important way to prevent laser hazards is safety education. It is strictly forbidden to view the laser beam with naked eyes and pay attention to operating procedures.

Identify the operation area and danger zone and put up eye-catching warning signs. Unauthorized personnel are not allowed to enter at will. They are required to wear appropriate protective glasses and protective gloves and have regular physical examinations, especially of the eyes.

Laser therapy device functions:

Laser therapy devices have the functions of reducing blood viscosity, lowering blood lipids, preventing thrombosis, treating and preventing hypertension, stabilizing blood pressure, strengthening the brain and memory, and improving clinical symptoms of sub-health, because light quanta can stimulate phagocytes, increase their capacity, accelerate the degradation of lipoproteins, reduce peripheral resistance, improve blood microcirculation, quickly relieve systemic symptoms, and improve activity endurance.

With the development of laser technology, laser medicine has gradually taken shape. Due to the unique advantages of laser therapy, it has solved a large number of problems that traditional medicine cannot solve, and has attracted widespread attention from the medical community at home and abroad. Laser equipment for basic biomedical research and clinical diagnosis is also a key area of ​​development at home and abroad.

To sum up, the application scope of laser therapy devices will become wider, and laser therapy devices will gradually replace traditional therapies in medicine and become the first choice of medical institutions.
