On the other hand, when the use of the tube pump is terminated when the tube pump is not used for a certain period of time to separate and store the tube (300).

That is, when the tube 300 is stored for a long time without being separated, the tube 300 is deformed by pressing by the protrusions 151 and 410 and pressing by each roller 220 and pressing by the indentation groove 161. Since this may occur, it is preferable to store the tube 300 separately when not in use for a long time.

Thus, when the tube 300 is to be separated, the cover body 500 is opened to open the front of the case 100, and then the restraining clip 400 is released to release the tube 300 and the tube in the state. What is necessary is just to separate 300, and then perform the sequential assembly of the restraining clip 400 and the cover body 500.

After all, the tube pump of the present invention is easy to separate and install the tube 300, so that even the general user can easily carry out it is possible to separate and store the tube 300, which is because even if not used for a long time tube 300 ) Deformation can be prevented.
