ABSTRACT:
A vacuum device and method for extraction of a substance from a fluid source, the vacuum device including an upper member that may be selectively, and operably, connected to a lower member. The upper member defines a bottom opening, and has a vacuum pump in fluid communication with the bottom opening. The vacuum pump is selectively coupled to an energy source. The lower member defines an inner cavity, a first opening, and a second opening, the inner cavity in communication with the first opening and the second opening. An elastic membrane defining an interior cavity is disposed in the inner cavity and is coupied to the first opening of the lower member. In use, the second opening of the lower member in placed in selective fluid communication with the fluid source, and the lower member is selectively coupled to the upper member such that the vacuum pump is electrically coupled to the energy source and the bottom opening of the upper member is in sealed contact with the first opening of the lower member so that the vacuum pump is in fluid communication with the interior cavity defined by the elastic membrane.
