Abstract
The present invention relates to an elastic tubing pump and more particularly to an elastic tubing pump. The pump has an elastic tube communicating with a liquid supply source, a pressing means for pressing at least two points of a section of the elastic tube to seal the liquid therein, a driving means for pushing the pressing means in one direction of the elastic tube, a locking means for firmly holding the elastic tube from being moved by the pressing means, a shifting means for unlocking the locking means according to the driving operations of the driving means and for advancing the elastic tube by the length of its compressed section. The driving means can accelerate to compensate for the possible decrease in the liquid's flow through the tube during a time of shifting the elastic tube by one section's length.
