Refurbished • Rental • Medfusion Model 3500 Syringe Infusion Pump • 1-Year Warranty
The Medfusion™ Model 3500 Syringe Infusion Pump is a compact syringe pump designed for controlled delivery of medications, fluids, blood products, and enteral solutions using compatible syringe configurations. United Infusion offers the Model 3500 as refurbished rental equipment for facilities requiring temporary, supplemental, or replacement syringe-pump capacity.
What’s Included
- 1× refurbished Medfusion Model 3500 Syringe Infusion Pump rental unit
Rental configuration note: United Infusion does not separately confirm the exact pole clamp, AC power cord, battery revision, lockbox, communication accessories, syringe files, PharmGuard configuration, or other accessories included with every rental unit. The supplied Biomedix reference includes a pole clamp with its own 3500-306 unit, but that does not establish inclusion with United Infusion rental inventory. Confirm the complete rental package before deployment.
Product Description
The Medfusion Model 3500 is a portable syringe infusion pump intended for precisely controlled fluid delivery. Manufacturer documentation supports applications including arterial, epidural, intravenous, intrathecal, subcutaneous, and enteral delivery, subject to the applicable software version, syringe configuration, medication, and facility protocol.
Current ICU Medical documentation for the Version 6 platform supports a wide variety of configurable continuous and intermittent delivery modes. V6 incorporates PharmGuard™ Medication Safety Software and allows facility-defined configurations containing profiles, libraries, drug programs, syringe definitions, soft limits, and hard limits.
The Model 3500 also incorporates FlowSentry™ pressure monitoring for rapid occlusion detection at supported syringe sizes and flow rates, pressure trending, post-occlusion bolus reduction, audible and visual alarms, configurable KVO, loading-dose and bolus functions, delayed start, standby, and other configuration-dependent options.
- Single-syringe infusion-pump design
- Compatible with manufacturer-approved syringe models and sizes from 1–60 mL
- Current V6 published infusion-rate range of 0.01–1130 mL/hr, syringe-size and rate dependent
- Continuous and intermittent delivery modes
- Body-weight and body-surface-area-based programming on supported V6 configurations
- Bolus and loading-dose programming when enabled
- Configurable Keep Vein Open (KVO) operation
- FlowSentry™ pressure monitoring on supported flow-rate/syringe combinations
- Pressure trend display and post-occlusion bolus reduction
- V6 PharmGuard™ Medication Safety Software
- Up to 16 Profiles per V6 configuration
- Rechargeable internal battery with automatic transition from AC to battery power
- Portable 3.8 lb pump design
Software-version note: United Infusion currently states that its Medfusion 3500 rental inventory includes software v6.0, v5.0, and v3.0.6. These versions should not be treated as interchangeable. Always verify the software version displayed during pump startup and use the matching manufacturer documentation and configuration for that individual unit.
Clinical lifecycle warning: ICU Medical / Smiths Medical states that Medfusion Model 3500 v3 and v4 pumps are no longer within their service life and should no longer be used for clinical care. Its December 2023 medical-device correction also identifies software versions before v6.0.0 as affected by multiple software issues and directs customers to ensure the most recent Medfusion software is installed. A seller statement that v3.0.6 units remain in inventory should therefore not be interpreted as manufacturer support for clinical use of v3 software.
Current safety note: FDA currently lists multiple open recalls and corrections involving Medfusion Model 3500 pumps. These include an open Class I recall for pre-v6 software, an open Class I recall involving certain Model 3500 pumps with Software 6.0.0 or 6.0.1, and open Class II actions involving force-sensor/occlusion performance and specified pumps manufactured or serviced with potentially affected barrel-clamp guides. Applicability depends on the individual pump's item number, serial number, installed software, manufacturing/service history, and completed corrective actions. Verify each rental unit against current ICU Medical and FDA information before clinical deployment.
Rental note: United Infusion states that its rental pumps are tested, serviced, maintained, and cleaned before delivery. Short- and long-term rental options and replacement support are available subject to the applicable rental terms.

Refurbishing Process
At United Infusion, we follow a comprehensive refurbishing process for infusion pumps to help ensure they operate safely and reliably. This process follows manufacturer guidelines and sanitation standards to meet high quality expectations.
Below are the key steps of our refurbishing process:
2. Disassembly
The pump is carefully disassembled to access internal components, including the motor, gears, tubing pathways, and electronics. All parts are handled with care to avoid added damage.
3. Cleaning & Sanitization
Appropriate disinfectants are used to thoroughly clean all parts and remove residual fluids, blood, or debris. This step follows sanitation standards to help ensure the device is free from contaminants.
4. Component Inspection & Replacement
Individual parts, including the motor, battery, display screen, buttons, and connectors, are inspected for wear, damage, or malfunction. Worn or damaged components are replaced with manufacturer-approved parts.
5. Calibration & Software Update
The pump is adjusted to support accurate fluid delivery rates using standardized testing methods, and calibration is verified against manufacturer specifications. The latest compatible software version is then installed to improve functionality.
6. Testing, Reassembly & Final Check
The pump goes through functional testing, including alarms, flow rate accuracy, occlusion detection, and bolus delivery. It is then reassembled, connections are checked, and a final visual and functional inspection is completed to confirm it meets safety standards and customer requirements.
"We needed our syringe pumps serviced for scheduled maintenance to continue to provide safe care. In the past, we had to send them off with a 6 weeks turn around time. Then we found United Infusion. 30 min down the road, 24 hr turn around and 30 minutes down the road. We are extremely grateful!!!"
