VACUUM DEVICE FOR SUBSTANCE EXTRACTION

摘要

A vacuum device and method for extraction of a substance from a fluid source the vacuum device including an upper member (20) that may be selectively, and operably, connected to a lower membrane. The upper member (20) defines a bottom opening (24) and has a vacuum pump (40) in fluid communication with the bottom opening (24). The vacuum pump (40) is selectively coupled to an energy source. The lower member defines an inner cavity, a first opening, and a second opening. An elastic membrane defining an interior cavity is disposed in the inner cavity and is coupled to the first opening of the lower member.
