System Overview
System Philosophy
The System 1 uses a software-based design and a user interface to provide an
adaptable perfusion system.
Each system device and sensor module contains software that allows it to transmit
and receive messages via a Controller Area Network (CAN). This design allows
users to:
•
Connect modules to any connection point on the system base
• Enable communications links between sensors and devices
• Select how they want pumps and an occluder to respond to alert and alarm
conditions
An additional advantage of this design is the ability to use advanced functions without
requiring specialized hardware. All pumps can be configured to deliver advanced
functions such as:
Roller and Centrifugal Pumps
•
Pulse mode
• Servo regulation to pressure or flow
Roller Pumps only
•
Master/Follower operation
• Cardioplegia volume tracking
• Automatic cardioplegia dose delivery
The System 1 uses an intuitive patient graphic interface to organize the system
information. This centralized monitoring helps the user to view current perfusion
parameters without having to look at multiple displays.
The System 1 Central Control Monitor (CCM) also serves as the central area for
controlling pumps, an occluder, and the gas flow system. Pumps and the gas flow
system also have local controls and displays that can be used interchangeably with
the central monitor controls. This allows the user to:
•
Remotely mount pumps and sensors
• Reduce tube lengths
• Reduce the prime volume of the extracorporeal circuit
