medical valve —— Three-Way Check Valve
Three-Way Check Valve FAQ (Simplified)
- What is a Three-Way Check Valve?
A: A medical valve with three ports (two inlets, one outlet) for fluid control in liquid transfer and medication mixing. It enables unidirectional flow switching (prevents backflow) and integrates pressure sensing.
- Key functions?
A:
✅ Fluid switching: Routes two inputs to one outlet (e.g., mixing drugs).
✅ Pressure monitoring: Real-time detection of line pressure.
✅ Backflow prevention: Unidirectional flow design.
✅ Medical-grade materials: Biocompatible (ISO 10993).
- How does pressure sensing work?
A: Embedded sensors measure inlet pressures, alerting systems to over/under-pressure risks. Data output via electrical signals (e.g., 4–20 mA) for automation.
- Typical medical uses?
A:
• IV systems: Mixing meds/fluids while preventing contamination.
• Dialysis: Switching blood/anticoagulant lines.
• Laboratory automation: Precision liquid handling.
- Why “two in, one out” configuration?
Optimizes mixture control (e.g., blending chemotherapy drugs) or input selection (e.g., choosing solvent A or B for a reaction).
- Safety features?
A:
• Fail-safe design: Auto-closure if power fails.
(When inlet flow stops, backflow reverses the internal mechanism to prevent reverse flow)
• Low pressure drop (<5 kPa) to minimize flow disruption.
• Sterilizable (steam/ETO) for reusable devices.
- Risks without it?
Cross-contamination, incorrect mixing ratios, and pressure-related equipment damage.
