Abstract:
An apparatus for rinsing an operation field during endoscopy comprising:an endoscope having a conduit provided with a proximal section and with a distal section which has an outlet opening; a liquid source in flow communication with the proximal section of the conduit; a compressed-gas source in flow communication with the proximal section of the conduit; first and second controllable valves between the proximal section of the conduit and the liquid source and between the proximal section of the conduit and compressed-gas source, respectively, the first and second valves being sequentially open so as to enable a controllable portion of liquid filling part of the proximal portion during opening of the first valve to be driven toward the outlet opening at an accelerating rate by a gas portion introduced into the proximal section upon opening of the second valve after the first valve has been closed.
