[0039] REFERENCE Figures 1 to 5 The peristaltic pump feeding system and the control method thereof of the application are further described.

[0040] For ease of description, spatially relative terms, such as "upper", "lower", "left", "right", and the like, are used in the embodiments to describe one element's or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device is inverted, elements described as being on the "lower" side of other elements or features would then be oriented on "upper" sides of the other elements or features. The exemplary term "lower" can therefore encompass both an orientation of lower and upper. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0041] Also, the relative terms "first" and "second" are used to differentiate between two components having the same name, but not necessarily requiring or implying any such actual relationship or order between the components.
