ENTRIFUGE BOWL
The Haemonetics disposable centrifuge bowl is the central element of any MCS+
disposable set. Two types of disposable bowls exist for the various MCS+ proce-
dures: the bell-shaped Latham bowl and the cylindrically-shaped blow molded
bowl (BMB).
An MCS+ disposable centrifuge bowl is comprised of the following sections:
!
The stationary section referred to as the “head” of the bowl.
!
The rotating section referred to as the “body” of the bowl.
!
The seal between these two sections.
Explaining the
general design of
the bowl
The head of the bowl, containing an inlet port and an outlet port, provides a
shield for the seal of the bowl. When the bowl is held upright, the inlet port is
located above the outlet port.
Note: When installing a bowl, the inlet port should be positioned facing the left
side of the centrifuge, and the outlet port should be positioned facing the right
side of the centrifuge.
The inlet port is used for attaching the donor-line disposable tubing. The inlet port
leads to the feed tube which passes through the core and transports blood into
the processing chamber.
The feed tube also allows non-selected elements to exit the inlet port as they are
returned to the donor. The outlet port provides the exit for the collected blood
components and connects to the effluent tubing of the disposable set.
The body of the bowl contains a core and the processing chamber for the blood
components.
The rotary seal of the bowl is attached to the body of the bowl by a ceramic
section. A properly functioning rotary seal is essential to MCS+ operation.
Caution: The functional characteristics of the rotary seal can be altered if the pres-
sure in the bowl becomes excessive. This can cause the seal to be raised like a
pressure valve. The operator must remain attentive to avoid twists or occlusions
in the effluent tubing, which could obstruct either the flow of air or fluids in the
effluent pathway.
