A precision medical device component that holds and dispenses contrast media during medical imaging procedures.

Product Specifications

Technical details and manufacturing context for Syringe Assembly

Definition
The syringe assembly is a critical component of contrast media injectors used in medical imaging (CT, MRI, angiography). It consists of a syringe barrel, plunger, and associated seals that work together to accurately measure, contain, and deliver contrast agents under controlled pressure. This assembly ensures sterile, precise, and reliable injection of contrast media into patients' bloodstreams for enhanced diagnostic imaging.
Working Principle
The syringe assembly operates by creating a sealed chamber (syringe barrel) where contrast media is loaded. A motor-driven plunger moves within the barrel, creating positive pressure to dispense the media through connected tubing to the patient. Precision sensors monitor volume and pressure, while seals prevent leakage and maintain sterility throughout the injection cycle.
Common Materials
Medical-grade polycarbonate, Stainless steel, Silicone rubber

Specialized Tooling

Application Fit & Sizing Matrix

Operational Limits
pressure: Up to 150 psi (10.3 bar) maximum working pressure
flow rate: 0.1 to 10 mL/sec typical, depending on syringe size and application
temperature: 15°C to 40°C (operating), -20°C to 50°C (storage)
slurry concentration: Not applicable - designed for homogeneous contrast media solutions only
Media Compatibility
✓ Iodinated contrast media (e.g., Iohexol, Iopamidol) ✓ Gadolinium-based contrast agents ✓ Sterile saline solutions for flushing
Unsuitable: Highly viscous suspensions or particulate-laden fluids exceeding 5 microns in particle size
Sizing Data Required
  • Required injection volume per procedure (mL)
  • Maximum injection flow rate requirement (mL/sec)
  • Compatibility with existing injection system connection interface (e.g., Luer lock type, diameter)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Plunger seal leakage
Cause: Material degradation from chemical incompatibility with medication, or wear from repeated friction against barrel wall
Barrel cracking or fracture
Cause: Stress concentration from improper handling or assembly, or material fatigue from repeated autoclaving cycles
Maintenance Indicators
  • Visible fluid leakage past plunger seal during operation
  • Audible clicking or grinding noise when depressing plunger, indicating seal friction or barrel obstruction
Engineering Tips
  • Implement strict material compatibility verification for seals with all intended medications and sterilization methods
  • Establish controlled assembly procedures with torque-limited plunger insertion to prevent barrel stress and seal damage

Compliance & Manufacturing Standards

Reference Standards
ISO 7886-1: Sterile hypodermic syringes for single use ANSI/AAMI/ISO 80369-7: Small-bore connectors for liquids and gases in healthcare applications ASTM D999-08: Standard Test Methods for Vibration Testing of Shipping Containers
Manufacturing Precision
  • Plunger fit: +/-0.05mm clearance for smooth operation
  • Needle hub taper: +/-0.02mm for secure Luer lock connection
Quality Inspection
  • Dimensional verification with coordinate measuring machine (CMM)
  • Leak test under pressure (e.g., 300 kPa for 30 seconds)
