A Simple 3-Point Checklist for Maintaining Liquid Handling Syringe Pumps

Precision and consistency are at the heart of healthcare delivery, and few devices embody that more than the syringe infusion pump. From intensive care units to research labs, these compact machines play a quiet yet vital role in administering critical medications and fluids with utmost accuracy.

But even the best-performing syringe pumps are only as reliable as the care they receive. Regular maintenance isn’t just about keeping the device clean, it’s about safeguarding patient safety, ensuring precision, and extending the machine’s working life. Fortunately, maintaining your syringe pumps doesn’t have to be complicated. All it takes is a structured, practical approach.

This blog will walk you through a simple, 3-point maintenance checklist to help your team stay proactive and confident when caring for your syringe infusion systems.

Why Syringe Pump Maintenance Is Non-Negotiable

Unlike larger infusion systems, syringe infusion pumps are designed for small-volume, high-precision delivery, making them especially crucial in paediatrics, neonatal ICUs, anaesthesia, and oncology. These pumps deliver medication in minute doses, where even a slight deviation in flow rate can have significant consequences.

Malfunctioning syringe pumps can result in:

That’s why building a strong routine around syringe pump care is key. The following 3-point checklist gives you a structured and actionable way to stay ahead of problems.

1. Inspect and Clean the Pump Thoroughly and Regularly

This may sound basic, but many technical issues with syringe pumps originate from neglecting routine cleaning and surface inspections. This should be the first step in your maintenance protocol.

a) Daily Surface Cleaning

Use a non-abrasive cloth with 70% isopropyl alcohol or a hospital-grade disinfectant to gently wipe the outer casing, control panel, and syringe mounting area. This helps prevent the buildup of contaminants, especially in high-touch areas.

Avoid: Spraying liquids directly onto the machine or using bleach-based cleaners that can degrade surfaces.

b) Syringe Holder & Tubing Check

Look for remnants of dried medication or bodily fluids around:

Residue here can affect syringe alignment and result in flow errors. To remove buildup gently, use a soft brush or a sterile cotton swab.

c) Casing and Cable Integrity

Ensure there are no cracks, loose joints, or exposed wires, especially around the power port and display panel. Inspect power cables and charging adaptors for fraying or weak connections.

Tip: Make this inspection part of your end-of-shift checklist in high-use environments like ICUs or labs.

2. Verify Functionality and Recalibrate Periodically

Syringe pumps rely on precise internal mechanisms such as stepper motors and software-driven delivery algorithms. Without regular functional checks and calibration, these components can become inconsistent, leading to subtle but dangerous inaccuracies.

a) Plunger Movement Test

Start the pump with an empty test syringe and monitor the plunger motion:

Abnormal behaviour could indicate issues with the motor drive or internal gears.

b) Alarm and Sensor Test

Simulate error conditions, like occlusion, syringe dislodgement, or air-in-line, to confirm whether the pump’s alarm system responds appropriately.

Some key indicators to test:

c) Flow Rate Accuracy

Run a controlled infusion with a known liquid (such as saline or distilled water) at standard rates (e.g., 1 mL/hr, 5 mL/hr). Measure the volume delivered over time and compare it with the expected output.

Calibration Frequency Tip: Perform this test every 30 days for standard hospital usage. In high-throughput environments, weekly checks are ideal.

3. Replace Consumables and Maintain a Clear Log

All syringe pumps have wear-and-tear parts. While many internal components are built for years of use, external or semi-mechanical components degrade faster, especially with frequent use.

a) Replace Syringe Mount and Grips

These components often endure mechanical stress during every use. Look for:

Over time, replacing worn mounts can drastically improve performance consistency.

b) Update Power Sources and Batteries

If your syringe pump is battery-powered or has a rechargeable unit, monitor its charge cycles. Replace the battery pack when:

c) Keep a Maintenance Log

This is essential for regulatory compliance (especially under ISO and NABH) and useful for internal tracking. The log should include:

Digital logs are easier to search and integrate into hospital asset management software.

Additional Best Practices

In addition to the above, here are a few bonus practices to elevate your syringe pump care protocol:

Train staff regularly: Even experienced staff benefit from refreshers on safe handling, loading syringes correctly, and recognising error signs.
Follow OEM guidelines: Refer to the manufacturer’s manual for specifications on syringe compatibility and part replacements.
Label your pumps: Label each unit, especially in larger setups, with a unique ID and maintenance schedule for quick reference.
Schedule preventive maintenance: Coordinate with biomedical engineers for quarterly or biannual in-depth checks beyond your routine inspections.
