CONTACTLESS FLUID PUMPING METHOD AND APPARATUS

摘要

A fluid pump apparatus for pumping a fluid from a fluid source to a fluid output comprises a first portion, such as a durable portion, and a second portion, such as a disposable portion. The first portion includes a fluid chamber having a wall and an internal cavity, an input port and an output port. A membrane forms a portion of the wall. The first portion further includes a magneto-sensitive element coupled to the membrane. The second portion comprises an actuator configured to contactlessly induce a reciprocating movement of the membrane by application of a time-varying magnetic field to the magneto-sensitive element, thereby facilitating pumping of the fluid through the fluid chamber.
