Abstract

Peculiarities of skin extension under vacuum applicators (nozzles) of various design was studied in 20 volunteers aged 18-25 years. The data obtained made it possible to chose optimal parameters of elastic membranes of the vacuum cups that produce stretch sufficient for vacuum-membrane skeletal muscle extension with minimal traumatic damage to the skin. Local negative pressure varied from 10 to 70 kPa. It was found that for 4.5-cm applicator with one 1.4-2.0-cm central orifice the optimal thickness of the membrane is 0.3 cm.
