WATERPROOF DEVICES INCLUDING SWITCHING UNIT Russian patent published in 2011 - IPC A61H23/02 H01H21/00 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medical equipment, namely to waterproof devices for skin processing, which include switching unit. In one of versions of implementation device contains case, waterproof commutation unit and upper part, attached to case. Case is made from two rigid elements, connected along gasket-provided seam and contains elongated handle part. On upper part located is surface, applicable for skin processing, adapted and made in such a way that it transfers relative movement to skin. Waterproof commutation unit contains first movable element, located on flat holder, and second movable element, located inside case. Flat holder is made in one of two rigid case elements and has opening, rotatable shaft, passing through opening, and gasket, which fits opening, for prevention of water movement along shaft and into internal part of case. Rectilinear movement of first movable element turns into rotating motion of rotated shaft by means of first gear and rotating motion of rotated shaft turns into rectilinear movement of second movable element by means of second gear. In other version of implementation device contains contacting with skin surface which includes water-absorbing material; and case unit, which has commutation unit. Commutation unit contains rotated shaft, which has fixed on it first gear and second gear; first movable element, which contains first rack, linked with first gear, located on flat holder, provided with through hole, and second movable element, which contains second rack, linked with second gear, located inside case unit. Rotated shaft passes through hole, surrounded by gasket. Rectilinear movement of first movable element turns into rotating motion of rotated shaft by means of first gear, and rotating motion of rotated shaft turns into rectilinear movement of second movable element by means of second gear.

EFFECT: application of claimed group of inventions will make it possible to ensure waterproofness in devices for skin processing.
