Infusion Pump Flow Rate Tester
The Infusion Pump Flow Rate Tester is specifically designed for testing the flow rate of sodium chloride solution in infusion sets. It is suitable for use by medical device manufacturers, third-party testing institutions, medical device inspection and research institutes, and research and educational institutions.
Applications
The infusion set flow rate tester is an instrument specifically designed for measuring and monitoring the flow rate of infusion sets. Its main uses include: - Flow Rate Measurement: Precisely measure the flow rate of the infusion set, usually displayed in milliliters per hour (ml/h) or drops per minute (gtt/min). - Flow Monitoring: Monitor the changes in flow rate in real - time during the infusion process, and promptly detect abnormal flow rate situations, such as the flow rate being too fast, too slow, or blocked, to ensure the safety and effectiveness of the infusion process. - Alarm Function: When the infusion flow rate exceeds the set normal range, the tester can emit audible and visual alarm signals to remind medical staff to take timely action and avoid potential medical risks. - Data Recording and Storage: Record and store information such as flow rate data and time during the infusion process, which is convenient for medical staff to view and analyze, and helps track and evaluate the patient's infusion treatment.

FAQ
1. What is the Infusion Pump Flow Rate Tester designed to measure?
The Infusion Pump Flow Rate Tester is specifically designed to test and verify the flow rate of sodium chloride solution delivered by infusion sets. It measures infusion flow accurately, typically in milliliters per hour (ml/h) or drops per minute (gtt/min), ensuring that the infusion set delivers fluid within the required range. The tester is widely used by medical device manufacturers, third-party testing institutions, inspection laboratories, and research or educational organizations to confirm that infusion sets meet flow performance requirements defined for disposable infusion devices.
2. What functions does the Infusion Pump Flow Rate Tester provide during testing?
The tester integrates multiple functions related to infusion flow performance. It can precisely measure and continuously monitor the flow rate in real time, helping users identify abnormal conditions such as excessive flow, insufficient flow, or blockage. When the measured flow rate exceeds a preset normal range, the tester can trigger audible and visual alarms to alert operators. In addition, the instrument records and stores flow rate and time data throughout the test, enabling subsequent review, analysis, and traceability of infusion performance.
3. Which standards are applicable to the Infusion Pump Flow Rate Tester?
The Infusion Pump Flow Rate Tester is designed with reference to GB 8368-2018. which specifies requirements for disposable infusion sets. This standard provides guidance for evaluating infusion performance, including flow characteristics under defined conditions.
4. What testing conditions are specified for infusion flow rate verification?
According to the test procedures, infusion sets with a drip rate of 20 drops/mL must deliver at least 1000 mL of sodium chloride solution with a concentration of 9 g/L within 10 minutes under a static pressure head of 1 meter. For infusion sets with a drip rate of 60 drops/mL, at least 1000 mL of the same sodium chloride solution must be delivered within 40 minutes under the same static pressure head. These conditions ensure consistency and comparability of flow rate test results.
