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 wali 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.用以將流體從流體源泵送至流體輸出之流體泵裝置包含第一部分諸如耐用部分、及第二部分諸如拋棄式部分。該第一部分包括流體室具有壁及內腔、輸入埠口及輸出埠口。膜形成該壁之一部分。該第一部分又更包括耦接至該膜之磁敏元件。該第二部分包括致動器係經組配來藉施加時變磁場至該磁敏元件而非接觸式地感應該膜之往復移動,藉此協助該流體之泵送通過該流體室。
