The application provides an infusion cassette of an infusion device, the infusion device and an infusion pump. The infusion cassette has a flow channel. The infusion cassette comprises a rigid assembly, an elastic diaphragm and a locking mechanism. The rigid assembly comprises a plurality of components stacked together. At least one of the components is provided with a groove. The elastic diaphragm is arranged between two adjacent components to seal the groove. The locking mechanism comprises a mounting frame and a liquid stopper fixed to the mounting frame. The liquid stopper can press the elastic diaphragm to close the flow channel. The locking mechanism closes or opens the flow channel through the liquid stopper. The mounting frame is movably connected to a main frame to enable the locking mechanism to switch between a closed state of closing the flow channel and an open state of opening the flow channel. The infusion cassette has high machining precision, simple assembly and small assembly error because the rigid assembly and the elastic diaphragm are injection molded parts. The possibility of unexpected displacement and swing of the elastic diaphragm is small. The infusion cassette can prevent excessive infusion and environmental hazards caused by liquid flow.
