Abstract (en)
A peristaltic pump comprises a main body (2); a contact body (3) slidably connected to the main body (2) and having at least one "vaulted" inner wall (13) for at least partly forming a contact surface (14); a flexible tube (4) at least partly positioned inside the main body (2) for allowing the transit of a fluid from an intake section (5) to a delivery section (6); at least two rollers (10) positioned inside the main body (2) and able to move along a circular trajectory so as to press the tube (4) against the contact surface (14) and produce corresponding constrictions moving from the intake section (5) to the delivery section (6); the contact body (3) being able to move between a first position, in which the inner wall (13) is at its closest to the rollers (10), and a second position, in which the inner wall (13) is at its furthest from the rollers (10) and a tube (4) access compartment (15) is formed.
