A dialysis device is provided comprising a disposable housing having a dialysate flow path along which dialysate received from a patient is subjected to contaminant removal when in operation, wherein said disposable housing comprises a storage chamber in fluid communication with the dialysate flow path for storing the dialysate therein； a controller for controlling the operation of said disposable housing； an interface means capable of operably coupling the controller and the disposable housing to enable the contaminant removal from the dialysate, and a fluid displacement means configured to move the dialysate along the dialysate flow path, wherein said fluid displacement means comprises a deformable diaphragm integrally formed with at least one wall of said storage chamber, wherein the flow path is fluidly sealed from the controller and interface means. A method of dialysis, a dialysis system and kits are also provided.本發明提供一種透析裝置，其包含：一可拋棄式殼體，具有一透析流路，當運作時，接收自病人之透析液係沿著透析流路進行污染物去除，其中可拋棄式殼體包含與透析流路流體連通且用於儲存透析液於其內之ㄧ儲存室；一控制器，用於控制可拋棄式殼體之操作；一介面工具，係能可操作連接控制器和可拋棄式殼體，使透析液能污染物去除；以及一流體位移工具，配置以沿著透析流路移出透析液，其中流體位移工具包含一可變形隔膜，係與儲存室之至少一璧面一體成形；其中，透析流路自控制器及介面工具被流體密封。本發明更提供透析方法、透析裝置以及套組。
