5. The Muravey Portable Laser Therapeutic Device

The Muravey therapeutic device is a portable and small-size apparatus. It has an array of 10 pulse laser diodes, which serve as its emitter.

The radiation wavelength is 890 nm, the maximum pulse radiation power ranges from 50 to 80 W (one laser diode makes 5 - 8 W); the power can be adjusted from zero to the maximum. The pulse repetition frequency is 80 Hz, and it can be modulated at a low frequency of 2.4 Hz (pulse-periodic mode). The device has an automatic timer and visual-acoustic indicators that show the time of the procedures start and termination.

An illuminated liquid crystal display (LCD) shows radiation power rate, procedure time, and the level of battery discharge. For your convenience, the device is protected against an accidental switch-on. When the device stands idle for a long time, it automatically switches off (protection against forgetfulness).

The device is user-friendly; you have only to choose radiation power and procedures duration in accordance with the attached guideline. After a session is finished, the device switches off automatically in a few minutes.

The power is supplied through a battery of the 1604A type (like Krona, Korund) or a mains adapter, which allows to use it both at home, and in the field conditions. A battery makes the device operation not less than 50 hours, and the indicator of battery discharge allows to replace it in time.

For the purposes of laser-magnetic therapy, MM50 and MM100 mirror magnetic attachments (with induction of 50 and 100 mT respectively) can be used.

The device doesnt weigh much, and it can be easily placed on a palm.
