Centrifugal Control Unit

Features

The primary function of a centrifugal pump is to move fluids through a
cardiopulmonary bypass circuit. Centrifugal pumps are used primarily for arterial
pumping applications and as augmented venous return pumps.
The System 1 centrifugal system consists of the control unit for control and display
functions and a drive motor which couples magnetically to a disposable centrifugal
pump head. The non-occlusive pump head moves fluid as a result of the pressure
gradient created by the rotation of the pump. The centrifugal control unit mounts on
a pole with a mounting bracket. The pump may be plugged into one of the 6 pump
connections on the base or into any of the base module connections. The drive
motor is pole-mountable and connects directly to a receptacle on the centrifugal
control unit.
The centrifugal control unit front panel display indicates the pump speed, flow rate
(if assigned from a flow meter), and alert, alarm, status, and error messages.
The motor speed may be controlled from either the Central Control Monitor (CCM) or
from the pump speed control knob on the front panel of the control unit itself.
In the Configuration area of the Central Control Monitor, a centrifugal pump can be
designated as primary, backup, or have no designation. A centrifugal pump can be
designated as a backup pump only for a primary centrifugal pump. Each of these
has unique functionality as described in the table below.

The use of the term "Pulse mode" refers to the variable pressure and flow waveforms that result from the
cyclic operation of the primary pump. Replication of a physiologic pulse from a natural heart is not obtained
with a pump speed controller. No claim of clinical benefit from the use of the Pulse mode has been reviewed by
global Regulatory Agencies.
When operating a device that shares a slide bar location, make sure the slide bar
displayed is for the device you intend to operate. The device name appears at the
top of the slide bar and the corresponding color appears on the central strip and the
scroll control.
When a centrifugal pump is designated as the primary pump, the system provides
the capability to operate the pump in Pulse mode. In this mode, the user can select
the Base setting and initiate Pulse mode operation from the Central Control Monitor.
Pulse flow operation can be discontinued from the control unit front panel or the
