Diode Laser Physical Therapy Equipment(MDL500),made in China. Opt:MDL50(50mW),MDL100(100mW),MDL500(500mW). 1).Irradiation treatment principle MDL-500 medical semiconductor laser instrument ,exports high power, longest wavelength, strong penetrability. high laser energy also can import personal deep organization, which are used for treating joint with acupuncture and diseases parts. have much effective, such as ease pain, diminish inflammation , contradict infection, promote organization rehabilitate. adjust inside body balance. stimulate to produce more. promote wound cicatrize. Its output power is 0 to 500mw, which can be regulated continuously. laser output is stable. that has small volume, light weight , good operation, extensively treat, bring expediently. 2).Adaptive symptoms *Nonnasality department: hemodia, stomatitis, exfoliation lip, nonnasality viscidity, after pulling outteeth, acute pericoronitis, trigeminal pain, disorganized mandible and joint. *Bone wound department: shoulder-joint inflammation, scathing parenchyma, tennis ball elbow, strained waist, promote cicatrization after operation, arthritis. *Nerve department: migraine, facial nerve paralysis, zona, neurlgia, scathing brain sequela. *Dermatology department: canker, bedsore, psoriasis, itch skin, dermatitis, bare fleck, honeycomb system inflammation. *Department of gynaecology: dysmenorrhea, pelvic infection, vulvitis, mastitis, wean pneumonia, diarrhea, enuresis, asthma. *Department of facial features: pharyngitis, acute tonsillitis, nasal septum nasosinusitis, auricle inflammation, tympanitis. *Cardiovascular Department: cardiasthenia, arrhythmia, miocardial infarction, angina, myocarditis,coronary heart disease, angiitis. 3).Technical parameter Specification Laser source: GaAlAs Output power :500mW Wavelength: 808nM Timed :0-99m Dimension (mm) :350×250×130 Weight :3Kg Electrical input :AC220Vor110V Warranty:1 year
