Description650nm semiconductor laserSemiconductor laser, with a wavelength of 650nm and strong penetrating power, is the latest generation of helium-neon laser therapy devices. Semiconductor laser therapy has the effects of analgesia, anti-inflammatory and anti-infection, promoting tissue repair, adjusting the balance in the body, stimulating regeneration, etc.Because semiconductor laser can produce good penetrating properties on human skin mucous membranes, blood vessels and other tissues, it can dilate capillaries, increase permeability, promote the absorption of exudates and improve blood circulation, reduce tissue edema, and activate cell activity,thereby improving the body's local immunity and achieving the purpose of anti-inflammatory and swelling.650nm laser irradiation of the ear can promote blood circulation, relieve pain, assist in the treatment of trauma, relieve otitis media, assist in the treatment of external auditory canal eczema and tinnitus, etc.1. Promote blood circulationIf the blood vessels in the patient's ear are blocked, it may affect the local blood circulation. The patient can be treated by laser irradiation, which can promote blood circulation and relieve discomfort symptoms to a certain extent.2. Relieve pain and assist in the treatment of traumaIf the patient's ear is injured, local swelling and pain may occur.Patients can improve through laser irradiation. 650nm laser can effectively improve tissue blood circulation, promote the healing of mucosal ulcers, and reduce nerve tissue edema, thereby quickly relieving pain and reducing inflammatory reactions.3. Relieve otitis mediaOtitis media refers to inflammation in the middle ear, which may be related to factors such as Eustachian tube dysfunction and pathogen infection. Patients may experience symptoms such as ear pain, ear canal water, and hearing loss.It is recommended that patients can be treated by laser irradiation under the guidance of a doctor, which can promote the disappearance of inflammation and relieve discomfort symptoms.4. Auxiliary treatment of external auditory canal eczemaExternal auditory canal eczema refers to eczema that occurs in the external auditory canal, auricle and skin around the ear. It may be related to contact with allergens, mental factors and other factors. Patients may experience symptoms such as ear itching, desquamation, and increased secretions.It is recommended that patients can be treated by laser irradiation under the guidance of a doctor, which can promote blood circulation and improve discomfort symptoms.5. Reduce tinnitusEar laser has a certain effect on alleviating tinnitus symptoms (tinnitus caused by otitis media, hearing sounds or noise).The 650nm semiconductor laser penetrates deeply into human tissues. Its irradiation can dilate the capillaries of the inner ear, increase permeability, improve local blood circulation, increase oxygen and exchange of local nutrients,enhance metabolism, promote vascular regeneration and recovery of damaged nerve tissue, and stimulate various factors to increase their activity, directly stimulate nerve endings and promote the acceleration of nerve impulse conduction due to the activity of biological enzymes.By adjusting certain mechanisms, the auditory conduction and auditory central function are restored, hearing is restored, and the occurrence of tinnitus is inhibited. Therefore, the treatment of deafness and tinnitus with semiconductor laser irradiation at the same time as drug treatment has important clinical value for the treatment of deafness and tinnitus.6. Promote relaxation and sleep PrincipleEar laser can promote physical relaxation, help reduce tension and anxiety, and thus improve sleep quality.In daily life, patients are advised to pay attention to the care of the ear area and avoid using hard objects to dig the ears to avoid damaging the ears. At the same time, patients also need to pay attention to keeping the ear canal clean and dry to avoid causing discomfort.
