Products Description
The Disposable Medical Three-way Stopcock is a sterile, single-use valve device designed for precise fluid or gas control in clinical settings. Manufactured from medical-grade polycarbonate or polypropylene, it features three ports (A/B/C) and allows flexible redirection of flow by simply rotating the valve handle. Widely used in infusion, drainage, anesthesia, and emergency care.
Working Principle
1Flow Switching: Rotate the handle (typically 90° or 180°) to open or close different flow paths: A→B, B→C, A→C, or fully off.
2Flow Regulation: Adjust rotation angle to control flow rate; some models include graduated indicators.
Key Advantages
✅ Infection Prevention:
Single-use design eliminates cross-contamination risk from repeated disinfection.
✅ Ease of Use:
Simple structure enables quick flow switching and rate adjustment by healthcare personnel.
✅ Precise Control:
Supports accurate fluid/gas delivery for treatments such as contrast agent injection, minimizing medication waste.
✅ Multi-Scenario Application:
Ideal for blood transfusion, chemotherapy, central venous catheterization, and anesthesia infusion.
Typical Clinical Applications
Emergency Medicine: Rapid drug channel switching (e.g., alternating vasopressors and saline).
Interventional Procedures: Multi-lumen delivery of contrast media, flushing fluids, and medications.
Long-Term Infusion: Minimizes repeat puncture, protecting vascular access (e.g., parenteral nutrition).
Usage Guidelines
Sterility Check: Ensure package integrity and valve cleanliness before use.
Clear Port Labeling: Indicate each port's function (e.g., "drug," "flush," "patient").
Air Elimination: Expel air before flow switching to avoid air embolism.
Proper Disposal: Discard after use in accordance with medical waste protocols-do not reuse
FAQs
🔹 Why single-use only?
To prevent residual drug interactions and contamination, ensuring patient safety.
🔹 Is it compatible with all medications?
Verify chemical compatibility-use coated versions for lipid-soluble drugs.
🔹 How to reduce operation errors?
Choose models with locking mechanisms and clear directional indicators; staff training is essential.
