| 1 | Definition | A medical syringe pump is an electrically driven infusion device that delivers medication or fluid from a syringe at a controlled rate. | It enables precise, continuous administration when gravity infusion is not sufficiently accurate. | Confirm that the device is intended for clinical infusion and supports the required syringe type and size. |
| 2 | Supported Syringe Sizes | Common configurations support syringes from approximately 5 mL to 50 or 60 mL; the exact range varies by model. | Syringe capacity affects maximum volume, operating time, and the achievable flow range. | Check compatibility with the hospital’s approved syringe sizes and local disposable-supply requirements. |
| 3 | Flow-Rate Range | Typical programmable rates range from about 0.1 mL/h to 1,000 mL/h, depending on syringe size and device design. | A wide range supports both low-dose neonatal therapy and higher-volume adult applications. | Compare the minimum and maximum rates using the specific syringe size required for treatment. |
| 4 | Flow Accuracy | Many clinical syringe pumps specify nominal flow accuracy of approximately ±2% to ±5% under defined test conditions. | Accurate delivery is important for potent drugs, small volumes, and long-duration infusions. | Review the complete accuracy specification, including start-up, compliance, syringe type, and test conditions. |
| 5 | Infusion Modes | Common modes include mL/h, dose rate, time-volume mode, bolus, loading dose, and intermittent or programmable sequences. | Multiple modes reduce calculation errors and support different clinical workflows. | Verify whether dose-rate programming requires patient-weight, concentration, and drug-library inputs. |
| 6 | Occlusion Monitoring | Pressure sensors detect downstream resistance; configurable occlusion thresholds are commonly provided in mmHg or kPa. | Early detection can help reduce interruption time and limit pressure-related bolus delivery after an occlusion clears. | Check threshold settings, alarm delay, pressure display, and automatic pressure-release behavior. |
| 7 | Bolus and Anti-Bolus Functions | Many pumps provide controlled manual or automatic bolus delivery and an anti-bolus mechanism after occlusion release. | These functions help manage line filling, start-up delay, and unintended post-occlusion fluid movement. | Review bolus limits, bolus speed, lockout options, and the manufacturer’s anti-bolus test data. |
| 8 | Alarms and Safety Controls | Typical alarms include occlusion, syringe empty or nearly empty, syringe displacement, low battery, air-in-line where applicable, and system fault. | Clear alarms support rapid intervention and reduce the risk of unnoticed infusion interruption. | Assess alarm volume, visual indicators, alarm history, mute duration, and human-factors usability. |
| 9 | Power and Battery | Most portable clinical units use mains power with a rechargeable battery; battery operating time depends on load, screen use, and battery condition. | Battery backup maintains infusion during transport, transfer, or temporary power interruption. | Confirm battery runtime, charging time, replacement method, battery-status display, and power-failure behavior. |
| 10 | Compliance and Procurement Review | Internationally marketed infusion pumps are commonly evaluated against IEC 60601-1, IEC 60601-2-24, and applicable electromagnetic-compatibility requirements. | Standards-based testing supports electrical safety, essential performance, and reliable operation in clinical environments. | Request current regulatory documentation, performance-test reports, quality-system evidence, calibration procedures, and after-sales service details. |
