AIM and AIM Plus Overview
The pumps share the same design and functionality other than the hardware and software differences
noted in Section 1.2.2, AIM and AIM Plus Differences.
1.2.1
Pump Description
The Abbott AIM and AIM Plus are single-channel infusion pumps designed to deliver fluids
intravenously or epidurally. Special safety features integrated into the design include an
over-pressure (occlusion) alarm, an air-in-line alarm, a back-up (safety) microprocessor, motor
parameter monitoring, and numerous failure backup modes to prevent single point failures from
endangering the patient.
The pump is powered by four 1.5V AA alkaline batteries, optional nickel metal hydride rechargeable
battery packs, or an AC power supply. The pump is microprocessor-based and is programmed
through a 24-key keypad on the front of the unit. The state of the pump is displayed using a
16-character by 4-line alphanumeric liquid crystal display (LCD) module. The unit requires
dedicated cartridges to deliver fluids through rotary peristaltic pumping action. Control of the pump
and of the cartridge assure accurate fluid delivery.
The pump detects occlusions and air in the fluid cartridge. Ifthe pressure at the cartridge exceeds the
specification occlusion alarm pressure, the instrument sounds an alarm and stops delivery. If air in
the cartridge exceeds. the pre-set sensitivity limit, the pump will alarm, stop delivering and not
proceed until the air is cleared (the air sensitivity setting is variable, and for the AIM Plus can be
deactivated, refer to the pump's System Operating Manual for more information).
The pump has several programming modes: TPN, Pain Management, Intermittent Delivery,
Variable Time Delivery and Continuous Delivery.
The pump contains a time-of-day clock and history storing capability. Significant events that take
place with the pump can be reviewed on the LCD display, along with time and date of occurrence.
The pump contains a printer connector that also allows printout of this history information when the
pump is connected to one of the two recommended compatible printers. Two different special printer
cables (depending on printer choice) are available from Abbott as accessory items.
For specific instructions regarding pump operation, refer to the AIM System Operating Manual or the
AIM Plus System Operating Manual.
