  • Switching device for irrigation fluids in a dental handpiece
    Patent number: 7217127
    Abstract: A switching device for an irrigation line includes two flexible supply tubes (4a, 4b), each of the tubes connecting a flask containing an irrigation fluid to a handpiece via a peristaltic pump. The device includes at least one compression element (34a, 34b) and control members (32) which can apply the compression element alternatively to each of the flexible supply tubes (4a, 4b) in such a way as to squeeze and block the tube. The control members (32) are designed such that, when one of the tubes is being squeezed in order to block the passage of the fluid through same, the other tube is not being squeezed so that the fluid can flow through the other tube.
