1.8 Disposable Blood Chamber
The CRIT-LINE Blood Chamber is a sterile disposable cuvette designed to insure a
consistent viewing area for the CLM III’s sensor in order to provide accurate,
repeatable measurements. The blood chamber is attached to the arterial side of the
dialyzer during the pre-dialysis set-up procedure. (See Section 2 for more
information).
WARNING: DO NOT USE THE BLOOD CHAMBER IF ITS PACKAGE HAS
BEEN OPENED, EXPIRED, OR ITS STERILITY HAS OTHERWISE BEEN
COMPROMISED PRIOR TO USE. THE PACKAGE HAS THE LOT NUMBER,
MONTH AND YEAR IT WAS MADE, AND EXPIRATION DATE.
The CLM III is highly sensitive to the optical properties of the CRIT-LINE Blood
Chamber. Reprocessing of blood chambers may sterilize the blood chamber, but
does not restore the optical properties of an unused, sterile blood chamber.
Therefore, it is important that a new sterile blood chamber be used during each
monitoring session. The viewing area of the disposable blood chamber should be
kept clean and free of obstruction. Air bubbles trapped in the CRIT-LINE Blood
Chamber may cause the instrument to underestimate the hematocrit measurement. A
blood clot may also alter the hematocrit measurement.
WARNING: PROPERLY DISPOSE OF THE BLOOD CHAMBER AFTER USE.
