Syringe needle flow tester

The Syringe Needle Flow Tester is designed to evaluate the flow characteristics of syringes by measuring the volume of liquid discharged over a specified time. It provides accurate and reproducible results for quality control, research, and development of syringes, anesthetic puncture kits, and pre-filled injection systems. The device integrates a test body, syringe fixture, flow meter, and control system for precise testing.

Application

This tester is suitable for a wide range of medical devices, including:

(1) Disposable anesthetic syringes – testing flow rate consistency for anesthesia delivery.

(2) Pre-filled syringes – ensuring accurate dosing and uniform liquid discharge.

(3) Standard hypodermic syringes – assessing flow characteristics for various liquid viscosities.

(4) Infusion needles – evaluating needle performance under different pressures.

(5) Catheter-mounted syringes – verifying flow rate for precise medical application.

(6) R&D and production line quality control – confirming syringe compliance with standards.
