<p>The device has a tubular handle (7) connectable to a liquid aspiration unit, and a rubber blade (A) which is arranged so as to separate two rows of aspiration intakes which are formed by the internal recesses or ridges 1 of the blade holder (B). The ridges (1) and a blade presser (C) rigidly associate the rubber (A), securing a toroidal portion thereof, when the blade holder (B) and the cover (D), complete with the handle, are joined by means of the screws (6). The remaining planar portion of the rubber blade (A) can thus flex in both directions, assisting, in each instance, the sliding imposed by the operator and closing the intakes located on the side opposite to the rake side of the blade (A), which is the side for collecting the liquid to be aspirated. <IMAGE></p> |
