METHOD TYPES
EZ PRO Quick Start
EZ PRO Quick Start Methods are designed for simple infusion or withdrawal applications, pumping at a
constant flow rate for either a predetermined time period until a preset volume is pumped, or running in
continuous operation until stopped. The PHD ULTRA
™
is supplied with the following pre-installed Quick
Start Methods, depending on the model of PHD Ultra pump you are using:
• Infusion Only (All Models)
The Infusion Only Quick Start Method is designed to pump liquids from the syringe at a set flow rate.
Users can set a Target Volume or Time period for operation. If no Target Volume or Time value is
entered, the pump runs continuously until the Mechanical Stop is reached or the user presses the
Method Stop button.
• Withdraw Only (Infuse/Withdraw and Infuse Withdraw Programmable Models)
The Withdraw Only Quick Start Method is designed to withdraw liquids into the syringe at a set flow
rate. Users can set a Target Volume or Time period for operation. If no Target Volume or Time value is
entered, the pump runs continuously until the Mechanical Stop is reached or the user presses the
Method Stop button.
• Infuse/Withdraw Sequence (Infuse/Withdraw and Infuse Withdraw Programmable Models)
The Infusion/Withdraw Quick Start Method is designed to cycle through an infusion operation
followed by a withdraw operation. The user can set separate flow rates for both the infusion and
withdraw sequences. In addition, the user must set a Target Volume for the Method.
• Withdraw/Infuse Sequence (Infuse/Withdraw and Infuse Withdraw Programmable Models)
The Withdraw/Infuse Quick Start Method is designed to cycle through a withdraw operation followed
by an infusion operation. The user can set separate flow rates for both the withdraw and infuse
sequences. In addition, the user must set a Target Volume for the Method.
EZ PRO Preloaded
Preloaded Methods have been designed by Harvard Apparatus engineers to accommodate commonly
employed pump control delivery protocols. These applications include infuse, withdraw and combined
infuse and withdraw protocols.
Preloaded Methods can be edited on Infuse/Withdraw and Infuse/Withdraw Programmable models of the
PHD Ultra. They are not available on the Infuse Only model.
The Preloaded Methods are continuously updated by Harvard Apparatus Engineers, so the Methods
installed on different pumps may vary. For details on specific use of these Methods, refer to the applicable
instructions in the Quick Start or User-Defined Methods sections of this manual.
EZ PRO User-Defined Methods
User-Defined Methods are created by the user through the application. To create a custom Pump Control
Method, you choose/set syringe specifications, then define the infusion or withdraw operations desired
using the available Pump Operation Profiles. User-Defined Methods can be stored on the PHD ULTRA
™
up
to the maximum memory capacity of the pump (approximately 800 Method steps). The user can manage
the library of stored Methods using convenient touchscreen controls.
