摘要： [Object] A configuration of a tubing pump capable of improving flow rate accuracy which is required, particularly, in infusion pumps for medical use is realized. [Solving Means] In a tubing pump that transfers a liquid in a tube which is detachably installed, a pump mechanism includes a valve mechanism unit that blocks up and opens the installed tube and a tube pressing mechanism unit that repeatedly presses the tube, and the tube pressing mechanism unit includes a pump block that is movably held by at least two guide shafts.

摘要： PROBLEM: To improve opening and closing operability of a door. SOLUTION: A tubing pump for transferring a fluid in a detachably attached tube 30 by a pump mechanism 50, the tubing pump is equipped with: a pump body 10 having a base 11 to and from which the tube 30 can be attached and detached; a door 20 pivotally supported to be rotatable with respect to the pump body 10, so as to open or close the base 11; switching urging unit A for urging the door 20 in an opening direction in a first rotation range R1 on a completely opened side and switching an urging direction to a closing direction in a second rotation range R2 on a completely closed side; and closing suppression unit B for suppressing an urging force in the closing direction by the switching urging unit A in the second rotation range R2.

摘要： PROBLEM: To reduce occurrence of an error of not closing a tube and to simplify a structure and an operation procedure. SOLUTION: In a tube clamp structure of a tubing pump for closing a tube 30 attached to and detached from a pump body 10 by a clamp device 40, the clamp device 40 is equipped with: a first holding piece 41; a second holding piece 42 engaged to approach or separate from the first holding piece 41; and an urging member for urging these first holding piece 41 and second holding piece 42 in approaching directions, is configured to hold and deform the tube 30 between these first holding piece 41 and second holding piece 42 for closing, and is detachably attached to the pump body 10.
