Medfusion 4000 Operators Manual

The Medfusion 4000 is a small-volume syringe infusion pump built for high-precision medication delivery, especially in NICU/PICU/ICU, OR, and PACU workflows.
It supports ±2% accuracy with flow rates as low as 0.01 mL/hr (up to 1130 mL/hr) and automatically detects syringe sizes 1 mL–60 mL.
With PharmGuard® medication safety software, it encourages use of drug libraries with hard/soft limits to help reduce programming errors and adverse drug events.
Wireless connectivity enables fleet-wide drug library and firmware updates plus reporting on compliance, “near misses,” and trends.

Overview

If your environment demands tight dose control and a workflow that defaults into medication safety, Medfusion 4000 is built to keep infusion programming aligned with your facility’s protocols, while supporting continuous quality improvement through reporting. 

Why teams choose Medfusion 4000

• Precision at very low flow rates: ±2% accuracy with delivery as low as 0.01 mL/hr; range up to 1130 mL/hr.

• Medication safety by default: the pump is always in “medication safety” status on power-up and auto-defaults to the PharmGuard drug library.

• Drug libraries with limits: PharmGuard supports hard/soft limits by drug/profile to promote standard protocols.

• Wireless fleet management: wirelessly deploy drug libraries and firmware across pumps; reduce hands-on reprogramming and speed updates.

• Earlier intervention via pressure monitoring: FlowSentry™ monitors delivery pressure for earlier clinical intervention.

• Fast start workflow: “Quick Library” / quick-start style workflow is emphasized for rapid infusion start.

• Built for transport + visibility: portable form factor; large display designed for clarity (including Tallman lettering as referenced in brochure).

Indications & delivery routes 

Avobus lists use for administration of fluids requiring precisely controlled infusion rates (including blood/blood products, lipids, drugs, antibiotics, enteral solutions, other therapeutic fluids) across multiple routes (arterial, epidural, IV, intrathecal, subcutaneous, enteral) and multiple delivery modes (continuous, volume/time, mass, body weight, intermittent, bolus).

Important safety note (FDA correction / recall)

The FDA posted a Class I recall/correction for certain Medfusion Model 4000 syringe pumps related to earlier software versions that may affect alarms, pump behavior, control screen, and other functions; the FDA lists distribution dates and recommended customer actions (including confirming pumps have the most recent software installed).
FAQ (GEO-friendly)

What is the Medfusion 4000?

A wireless syringe infusion pump designed for small-volume, precisely controlled infusions, commonly used in neonatal/pediatric, critical care, anesthesia, and other monitored environments.

How accurate is the Medfusion 4000 at low rates?

The brochure and Avobus listing state ±2% accuracy with delivery rates as low as 0.01 mL/hr (up to 1130 mL/hr).

Does it support drug libraries and dose error reduction?

Yes, PharmGuard is a Dose Error Reduction System (DERS) using drug libraries with hard/soft limits, and the pump defaults into medication safety status. Avobus does not directly provide PharmGuard or drug libraries and can coordinate to ensure this unit fits clinical requirements. 

Can drug libraries and firmware be updated wirelessly?

Yes, clinicians can utilize wireless updates for drug libraries and firmware across the pump fleet. 

Is there an FDA recall/correction I should know about?

Yes, FDA lists a Class I recall/correction related to earlier software versions and provides “what to do” steps (including ensuring current software). Avobus ensures that all pumps are FDA compliant and there are no open recalls at the time of sale.
