Abstract:
1. A peristaltic pump including: (a) a plurality of rollers that roll over a flexible tube portion of an irrigation line connected to a supply of fluid for surgical or dental use; (b) first means capable, in succession, of receiving the flexible tube portion in front of a plane in which the rollers move, then bringing the flexible tube portion underneath the rollers and then finally pressing the flexible tube portion against the rollers; (c) a slide that defines a housing for receiving the flexible tube portion and movements of the slide are controlled by a handle, wherein the slide and the handle are both pivotally mounted about a common shaft integral with a frame of the peristaltic pump; and (d) a large surface of the frame parallel to the plane in which the rollers move, wherein, during movement that closes the slide, the handle and the slide are first of all pivotally coupled and both pivot about the common shaft thereof until the slide abuts, via a tip of the slide, against the large surface of the frame of the peristaltic pump, wherein a base of the slide is arranged at a distance from the large surface of the frame, wherein the handle then is uncoupled from the slide and continues to pivot about the common shaft thereof, forcing the slide to make a swiveling motion that tends to return the base against the large surface of the frame of the peristaltic pump and a vertical translation motion upwards into a position in which the slide extends parallel to the large surface of the frame of the peristaltic pump.
