FIELD: medicine.SUBSTANCE: group of inventions relates to medicine. Portable deep leg vein massager with a motor and straps attached to a human leg, for applying pressure only along a segment of the leg circumference, includes at least a basic holding plate, two independent steps of mechanical assembly, at least two belts, at least one battery and an adjustable timer switch. On the base holding plate is an internal cartridge, designed to maintain independent mechanical devices in the collection for compression-decompression in segmented steps and connected to the straps, through which it is attached to the calf opposite to the tibia. Each mentioned step includes a mechanical device for applying a compression-decompression force to the surface area corresponding to the calf. Steps in which the lamellar segments lying on the surface of the calf are pushed and pulled by mechanical devices at each stage are supported by the inner plate of the cartridge. Two belts connect the lamellar component located near the tibia and covering the tibia opposite the more or less flat calf along the entire length with the surface of the support plate. At least one battery is attached to the tibia plate to supply power to a mechanical device mounted to compress and decompress calf surface with a segmented component of each step. Adjustable timer switch is electrically connected to battery power to turn the mechanical device assembly on and off, as well as to compress and decompress the steps of the mechanical assembly, which cyclically contract and expand on the calf of the leg to make the blood of the deep vein flow to the heart, as a result, control of the lamellar component of segmented surface to perform compression – decompression on calf local portion is carried out not along the circumference, but in synchronization with impact on adjacent regions of the calf, which are positioned in line with segment, by sequentially turning on and turning off the power of the mechanism, which i
