Casing is made from transparent silicone material with central opening closed from the top with protective cover provided with air openings. Circular cavity is divided by circular rib into two vacuum chambers each of which chambers are provided at the top with opening designed for communicating their cavities with atmosphere and having outside valves, said vacuum chambers being closed with two elastic membranes so as to define two smaller chambers. Vacuum pump has first, second and third flexible elastic members with openings where outer valve and two inner valves are positioned. First member is positioned in upper part within casing opening; second and third members are positioned opposite and below first member, at an angle thereto. Second and third members are connected with edges of slot provided in circular rib and with edges of opening in upper part of casing so as to define working chamber of vacuum pump. ^ EFFECT: wider range of objects held on human body. ^ 2 dwg |
