Pressure
monitors
The pressure monitors (DPM/SPM) should be cleaned daily in the following
manner:
" Depress and hold the white ring (as if installing the disposable filter).
" Wipe the silver rod thoroughly with a damp, lint-free cloth, using a circular
motion. Cloth may be dampened with water, disinfectant solution or alco-
hol per the site’s local standard operating procedures.
" Dry the rod and release the pressure on the ring.
Caution: Ensure that the pressure monitor is allowed to dry completely before in-
stalling the disposable set.
Air detectors
The air detectors are designed with a groove to hold the disposable tubing. The
contents of the tubing are monitored by the sensors, which are located internally
on either side of this groove.
The operator should use warm water and lint-free gauze to clean and dry in
between the tubing groves. The groove should be kept free of any particles, such
as powder residue from disposable gloves, since this could lead to an erroneous
detection of air.
Note: If a procedure is interrupted due to an air detector alarm and no air bub-
ble(s) are visible, the operator should remove the tubing and clean the groove be-
fore continuing the collection procedure.
Optical sensors
The lenses of the optical sensors must be kept completely free of particles or
debris, which could produce inaccurate readings and influence the MCS+ perfor-
mance. The operator should use only water and lint-free gauze to clean and dry
the lenses.
Caution: If any cleaning solution should come into contact with the optical sen-
sor lenses, they should be immediately cleaned with lint-free gauze and warm
water, then thoroughly dried. Cleaning solution can leave a “opaque” film on the
lens.
Anticoagulant drip monitor
The optical sensor of the AC drip monitor is located on the interior of the drip
chamber holder. The operator should immediately wipe away any AC solution
or other liquid which may have dripped on the lens to avoid erroneous readings.
