Feeding fluids and suction
 Feeding fluids
Securely insert a syringe into the slit of the biopsy valve and press the plunger.
 Suction
Depress the suction valve to aspirate excess fluids or other debris obscuring the
endoscopic image (see Figure 4.3).

Do not depress the suction valve while feeding fluids.
Otherwise, the fluids will be aspirated into the suction pump.
• Avoid aspirate of solid matter or thick fluids; channel or valve
clogging can occur. If the suction valve clogs and suction
cannot be stopped, disconnect the suction tube from the
suction connector on the suction valve. Turn the suction
pump OFF.
• When aspirating, attach the biopsy valve cap to the main
body. Failure to do so can reduce the efficacy of the
endoscope's suction system and may cause patient debris to
leak or spray from the endoscope, posing an infection-control
risk (for biopsy valve MD-495 only).
During the procedure, make sure that the suction bottle does
not fill completely. Aspirating fluids into a full bottle may
cause the suction pump to malfunction.
