Tubing Connector Component – Machinery and Equipment Manufacturing

Component Specifications

Definition

A specialized medical-grade connector designed to securely join tubing segments in contrast media injection systems, maintaining sterile fluid pathways while withstanding high-pressure injection cycles during CT, MRI, and angiography procedures. It features luer-lock or proprietary coupling mechanisms to prevent accidental disconnection.

Working Principle

Operates by creating a secure, pressure-resistant seal between tubing ends through mechanical locking (e.g., luer-lock threads) or compression fittings. The connector maintains fluid integrity by preventing leaks, backflow, or contamination during high-pressure contrast media delivery, typically at 300-1200 psi.

Materials

Medical-grade materials: Polycarbonate (body), Silicone or Polyurethane (seals), Stainless Steel 316L (locking components), BPA-free plastics. Biocompatible, sterilizable via autoclave (up to 134°C) or gamma irradiation.

Technical Parameters

Flow Rate 1-10 mL/s
Connection Type Luer-Lock (ISO 80369-7), Push-to-Connect
Leak Resistance Zero leakage at max rated pressure
Pressure Rating Up to 1200 psi (82.7 bar)
Temperature Range -20°C to 100°C
Tubing Compatibility 1/8" to 1/4" ID, various wall thicknesses

Standards

ISO 80369-7, ISO 594-1, ISO 594-2, DIN 13969, FDA 21 CFR Part 820

Incompatibility causing fluid leakage
Material degradation from contrast media chemicals

FMEA Triads

Trigger: Seal material degradation from repeated sterilization
Failure: Fluid leakage during high-pressure injection
Mitigation: Use chemically resistant seals (e.g., FKM fluorocarbon) and implement replacement schedules based on cycle counts

Trigger: Improper connection torque
Failure: Thread stripping or incomplete seal
Mitigation: Train staff on proper hand-tightening techniques and use torque-limiting devices where specified

Trigger: Material incompatibility with contrast agents
Failure: Cracking or swelling of connector components
Mitigation: Verify chemical compatibility charts for specific contrast media (ionic/non-ionic) and connector materials

Frequently Asked Questions

What sterilization methods are compatible with contrast injector tubing connectors?

Most connectors are compatible with autoclave sterilization (134°C, 2 bar), gamma irradiation (25-40 kGy), and ethylene oxide (EtO) sterilization. Always verify manufacturer specifications.

Are these connectors interchangeable between different contrast injector brands?

Not universally. While luer-lock connectors follow ISO standards, proprietary locking mechanisms (e.g., Bayer Medrad, Bracco Empower) require brand-specific connectors. Always check compatibility charts.

What causes connector failures in high-pressure applications?

Common failures include thread wear from repeated use, seal degradation from chemical exposure, and cracking from over-torquing. Regular inspection and replacement per manufacturer guidelines prevent failures.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
