  • PERISTALTIC PUMP
    Publication number: 20120282126
    Abstract: The invention relates to a peristaltic pump for use in medical technology with a stator 40 and a rotor 20, whereby the stator 40 has an occlusion bed 12, which forms the contact area with a tube 30 accommodated within, and the rotor 20 is provided with rolling elements suitable for occluding a tube accommodated between the occlusion bed 12 and the rolling elements 24. The occlusion bed 12 thereby has at least in part an electrically conductive surface for reducing and/or preventing electrostatic charging of the tube 30.
