Overview

The Medfusion 2001 is a compact, microprocessor-controlled syringe infusion pump designed for meticulous low-volume drug and fluid delivery in the hospital. It accepts a broad range of syringe brands and sizes from 1 to 60 ml and automatically senses the loaded syringe size, reducing setup steps and the chance of size-entry error. Delivery accuracy is rated at ±3%, excluding syringe-to-syringe variation, which makes the pump well suited to pediatric, neonatal, and critical-care applications where small, precise volumes matter. The pump runs on AC power or internal rechargeable batteries, so it transitions cleanly between bedside use and intra-hospital transport. A custom-program mode lets biomedical staff preselect which infusion modes, maximum rates, alarm settings, volume limits, and KVO rates are available to clinicians, and a lockout feature limits access to those parameters once configured. Originally built by Medex, Inc. under the Medfusion brand, the 2001 established the platform conventions that later Medfusion syringe pumps carried forward.

Display and User Interface

The Medfusion 2001 presents programming and delivery information on a multi-line LCD supported by dedicated status LEDs and an audible alarm. The display shows the active syringe size and manufacturer, programmed rate, volume limit, KVO rate, total volume delivered, and a battery-voltage indicator, so the clinician can confirm the full delivery context at a glance. Programming follows a guided, step-based sequence: the operator confirms or selects the syringe manufacturer and size, sets the infusion mode, and enters rate and limit values using the rate-selection and enter keys. Status indicators communicate operating states such as priming, delivery, standby, battery-in-use, and battery-charging, while alert LEDs flag conditions including occlusion, near-empty, empty, low battery, and depleted battery. The custom-program lockout, configured by biomedical staff, restricts which parameters a bedside user can change. This combination of explicit on-screen confirmation and configurable access supports consistent, repeatable programming across users and shifts.

Infusion Modes and Delivery Control

The Medfusion 2001 supports four infusion modes: Continuous, Volume Over Time, Intermittent Auto, and Intermittent Manual. It does not include a bolus function. Flow rates range from 0.01 to 378.0 ml/hr, with the available maximum determined by the selected syringe size. A programmable Volume Limit can be set from 00.00 up to the maximum capacity of the loaded syringe, with a minimum programmable volume of 0.05 ml in 0.01 ml increments; once the limit is reached, the pump can transition to a Keep Vein Open rate. The KVO rate is programmable from 0.1 to 9.9 ml/hr in 0.1 ml increments and cannot exceed the primary delivery rate. The cumulative total volume delivered is tracked from 000.00 to 999.99 ml in 0.01 ml steps. Occlusion sensing is selectable across four force settings to match the clinical application. Using a Monoject 35 ml syringe as the OEM reference example, the Low setting corresponds to roughly 4.0 lbf (about 5.96 psi maximum theoretical), Normal to 11.0 lbf (about 16.4 psi), Mid to 13.8 lbf (about 20.5 psi), and High to 15.0 lbf (about 22.3 psi). These are theoretical maxima; actual output pressure is typically lower and varies with syringe size, tubing, catheter gauge, and in-line devices.

Software Versions and Platform Evolution

The Medfusion 2001 covered by the OEM Operations Manual (P/N 9-61-20000-0-6, Revision 6) runs software versions 1.4 and 1.4A. Software version 1.4 supports five syringe options across four manufacturers: Becton-Dickinson (1, 3, 5, 10, 20, 30, 60 ml), Monoject (1, 3, 6, 12, 20, 35, 60 ml), Terumo (1, 3, 5, 10, 20, 30, 60 ml), Becton-Dickinson Glass (1, 3, 5, 10 ml), and Abboject (50 ml). Software version 1.4A retains those options and adds three additional manufacturers: B. Braun (2, 5, 10, 20, 30, 60 ml), Fresenius (10, 50 ml), and Perfusor (50 ml). A pump may display a third software digit reflecting an update that does not affect operation and is not visible to the user; if the first or second digit does not match the manual, the manufacturer should be consulted to confirm the correct configuration. Occlusion-force labeling also evolved with software: on version 1.4 the selected force appears as an L, M, or H suffix after the syringe size, and on later software the Mid setting is relabeled as INT (I). When sourcing or servicing a 2001, confirming the installed software version is the first step in matching syringe libraries, occlusion-force tables, and documentation.

Battery Operation, Mounting, and Syringe Loading

The Medfusion 2001 operates on AC power (95–135V, 60 Hz) or on internal rechargeable batteries, with international voltage configurations available. At 77°F, a full 16-hour charge with the pump off supports at least 10 hours of operation at 5.0 ml/hr using a 60 ml syringe; runtime varies with rate and syringe size. The batteries recharge while the pump is connected to AC, including during operation, and a low-battery alert provides approximately 30 minutes of warning before depletion at rates of 5 ml/hr or less. The pump weighs 2.5 lbs and measures 4.5 in wide by 3.0 in high by 7.5 in long, and it can be mounted to a pole or rail using the appropriate attachment or laid on a benchtop. The syringe loads into a side-mounted saddle; the clear syringe clamp must capture the syringe finger tabs in the clamp groove, and the plunger must be seated in the plunger holder so the pump can sense size and detect a dislodged syringe. Confirming correct loading before delivery is essential to accurate measurement and proper alarm behavior.

Connectivity and Standalone Operation

The Medfusion 2001 is a standalone syringe pump. As a device introduced in the mid-1990s, it does not provide network connectivity, wireless drug-library updates, or electronic medical record integration, and it does not host a dose-error-reduction drug library of the type found on later smart pumps. Delivery parameters are entered directly at the device for each infusion, and programming control is governed by the custom-program mode and lockout rather than by a networked formulary. For facilities standardizing on the 2001, this means medication safety practices rely on local protocols, independent double-checks, and the pump’s built-in alarms and volume/KVO limits rather than on server-pushed libraries. Documentation of delivered volume is read from the pump’s total-volume display and recorded per facility procedure. Where centralized infusion data capture or wireless library management is a requirement, facilities typically pair legacy 2001 fleets with manual charting workflows or evaluate later Medfusion platforms that add those capabilities. IPR Medical can advise on where the 2001 fits within a mixed fleet and what its operational limits are relative to newer syringe pumps.

Service and Maintenance Considerations

Several Medfusion 2001 characteristics are service-relevant when acquiring or maintaining units. Occlusion-force settings are not changed by the bedside user; adjusting the force table requires the service manual, the manufacturer, or qualified biomedical personnel, and the selected force is reflected by the L/M/H (or INT) indicator on the display. The internal rechargeable battery is a wear item, and a pump that no longer holds its rated runtime is a candidate for battery service before deployment. The 2001 also has a documented hardware change tied to serial number: pumps subsequent to serial number 33601, and earlier pumps retrofitted with the updated plunger holder/track subassembly, use a revised plunger sensor arrangement, so confirming the serial number and any retrofit history helps match service parts and expected behavior. Because the platform is legacy, exact OEM accessory and assembly SKUs are not always cataloged publicly; IPR Medical confirms the correct part for a given revision rather than substituting an unverified number. Routine functional checks, occlusion-alarm verification, and delivery-accuracy confirmation should follow the OEM service manual before a unit returns to clinical use.

FDA Device Corrections and Safety Bulletins

The FDA recall database records one device correction associated with the Medfusion 2000 series, which includes the Model 2001. Under Recall Z-1060-03, recalling firm Medex, Inc. initiated a correction on June 9, 2003 to address an inadequate warning label concerning use of the pump in conjunction with Extracorporeal Membrane Oxygenation (ECMO) procedures. Rather than a removal from service, the correction was a labeling action: the firm notified consignees by letter and supplied a warning label to be affixed to each pump and to the front cover of the instruction manual. The action covered the 2000-series general-use and regional variants (including 2001, 2001E, 2001G, 2001H, 2001T, and related configurations, along with the companion 2010 family) and reflected a documented distribution of roughly 59,938 units worldwide. The FDA record shows the action was posted on July 29, 2003 and terminated on March 13, 2006. The specific recall classification level is not stated in the openFDA record. Facilities that acquire a 2001 should verify that the ECMO-related warning label is present on the pump and in the manual, and should confirm current labeling and any later safety communications directly with the FDA.

Because FDA device corrections and safety communications may be updated or expanded after the date of this listing, IPR Medical recommends that facilities also check the FDA’s official resources directly to ensure they have the most current information.
