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.
Standards
The instrument is designed to meet the following standards:
(1) YY 0321.1: Disposable anesthetic puncture kit (China)
(2) YYB: Stainless steel injection needle for pre-filled and sealed syringes (China)
Optional compliance with international standards:
(3) ISO 7886-1: Sterile hypodermic syringes – Part 1
(4) ISO 8537: Single-use sterile needles and syringes
Features
(1) Measures syringe flow rate accurately over a fixed time interval.
(2) Integrated control system for precise pressure and flow management.
(3) Supports different syringe sizes with customizable fixing fixtures.
(4) Real-time monitoring of test parameters, ensuring reliable results.
(5) Easy-to-use interface for rapid setup and operation.
(6) Compact design suitable for laboratory or production environments.
