Tube and tube pump

A tube for use in a tube pump for pumping a fluid through compression of the tube by a compressing mechanism in association with movement of the compressing mechanism along the tube, comprising:

• a wall portion of elastic material, the wall portion having a hollow portion for transporting a fluid,
• wherein the wall portion includes mutually contacting wall portions which surround the hollow portion and which are to be compressed so as to contact one another,
• the mutually contacting wall portions include:
• readily contacting portions that readily contact one another at a given level of compressing force;
• and
• contact resistant portions that contact one another only at a higher level of compressing force than the readily contacting portions,
• wherein a thickness of the wall portion around the hollow portion varies so that a higher level of force acts on the contact resistant portions than on the readily contacting portions.

• wherein a curvature of an outside of the wall portion is smaller than a curvature of the hollow portion, and
• the wall portion further includes compressing wall portions for applying compressing force to the contact resistant portions, the compressing wall portions having corner portions.
