During drug delivery, ensuring precise dosing is critical—particularly for medications administered in small volumes and high concentrations. Any deviation in flow rate can compromise patient outcomes and pose serious health risks. These pumps must therefore meet rigorous dosing accuracy standards, including IEC 60601-2-24, across a range of flow rates.
The precision of the balance used directly impacts the reliability of flow rate measurements, particularly at low flow rates. Selecting the right balance is crucial for verifying pump performance and requires careful consideration of key parameters, including readability, capacity, and linear deviation. However, achieving reliable measurements goes beyond the equipment itself.
Environmental factors—like temperature and humidity fluctuations—balance drift, and electrostatic interference, can distort dosing accuracy verification. Identifying and mitigating these sources of error is essential for maintaining accuracy.
To overcome these challenges, robust testing protocols that account for environmental variables and dynamic testing conditions must be implemented. By addressing these sources of error and utilizing advanced weighing solutions, labs can uphold compliance with regulatory standards and protect patients.
