Abstract
A variable diameter aspirating tip adapted to be connected at the end of a suction hose which comprises a conduit section having connected to one end a nozzle formed of a flexible material which defines an orifice capable of expanding between a minimal diameter and a maximal diameter. An expander, slidably disposed within the flexible nozzle, is connected to an actuator. The expander is normally proportioned so as to have a diameter greater than the minimal diameter of the orifice. By effecting relative displacement between the expander and the nozzle, the size or diameter of this orifice is varied accordingly.
