FIELD: medical engineering. ^ SUBSTANCE: device has handle, engine located therein, solid head having longitudinal axis, and neck member, placed between the handle and head member. The first and second bristle holders are mounted on the head member. The first bristle holder performs angular oscillations or rotates. The second bristle holder performs reciprocating motion as a whole in head longitudinal axis direction. The driven system has shaft connected to the second bristle holder, and lever mainly directed towards head longitudinal axis and connected to the first bristle holder. ^ EFFECT: high-quality cleaning action. ^ 4 cl, 27 dwg |
