• When aspirating, attach the biopsy valve to the instrument channel port. If the valve
is not attached properly, it can reduce the efficacy of the endoscope’s suction
system and may cause patient debris to leak or spray. It can pose an infection
control risk.
• For MD-495
When aspirating, attach the cap to the main body of the biopsy valve. An uncapped
biopsy valve can reduce the efficacy of the endoscope’s suction system and may
leak or spray patient debris or fluids, posing an infection control risk.
• When aspirating, maintain the suction pressure at the lowest level necessary to
perform the procedure. Excessive suction pressure could cause aspiration of
and/or injury to the mucous membrane. In addition, patient fluids could leak or
spray from the biopsy valve, posing an infection control risk.
• Avoid aspirating solid matter or thick fluids; channel or suction 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, detach the suction valve, and remove solid matter or thick fluids.
During the procedure, make sure that the suction bottle does not fill completely or
overflow. Aspirating fluids into a full bottle may cause the suction pump to
malfunction.
