Method and device for fluid transfer

摘要

There is provided a method and device for fluid transfer. The device comprises a housing-like body with a wall having a concavity. Inside the housing there is disposed a magnetically activatable diaphragm capable of forming, in conjunction with the concavity, one or more pocket-like chambers. The housing also includes an inlet and outlet aperture. The device includes a plurality of means for producing magnetic fields arranged in proximity to the concavity and adapted to generate, in a predeterminable sequence, a plurality of magnetic fields of controllably changing polarities and intensities producing cycles of dynamic deflections of the diaphragm. By means of the magnetically generated dynamic deflections of the diaphragm, the pocket-like chambers are peristaltically manipulated to move fluid from the region of the inlet aperture through which the fluid is drawn in, towards the region of the outlet aperture, through which the fluid is expelled.
