Infusion Pump Flow Rate Tester

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.

Technical Parameters

Parameter	Specification
Testing Range	Wide flow rate testing range (e.g., 1 - 2000ml for some testers), adapting to different types/specifications of infusion sets (varies by catheter specifications)
Testing Accuracy	High accuracy for flow rate measurement (e.g., ±5ml/h or ±0.1gtt/min, etc.) to ensure test result accuracy
Static Water Level Height	Adjustable range: usually 0 - 1000mm, meeting requirements under different testing conditions
Temperature Control Range	Usually 5 - 90℃, simulating infusion situations under different temperature conditions
Fixtures	Adapt to various catheters; customized according to catheter specifications to firmly hold infusion sets of different specifications during testing
Flow Calculation	Adopts methods like the weighing method for flow calculation, ensuring accurate flow measurement
Alarm Threshold	Allows users to set the alarm threshold; triggers an alarm when the flow rate exceeds the set range

Accessoriess

Standard accessories include: specialized fixing clamps for different types of infusion sets (for securely holding various infusion sets), connecting tubing (for setting up the flow path to complete flow rate testing), equipment calibration auxiliary parts (to ensure testing accuracy), operating manual, and calibration certificate.

Test Procedures

Infusion Flow Rate

For infusion sets with a drip rate of 20 drops/mL, the infusion set should deliver at least 1000 mL of sodium chloride solution [mass concentration p(NaCl) = 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, the infusion set should deliver at least 1000 mL of sodium chloride solution [mass concentration p(NaCl) = 9 g/L] within 40 minutes under a static pressure head of 1 meter.
