HAEMONETICS HARMONY Smart Suction Suction pump Good working condition With the user manual FEATURES: Core Functional Features Auto-regulating suction force: The device automatically adjusts suction pressure when air is detected in the aspiration line, helping to reduce damage to delicate tissue and blood cells during suction. Gentle on red blood cells (RBCs): Suction is capped at around 150 mmHg maximum to help protect RBC integrity and reduce hemolysis compared with higher, non-regulated suction sources. Consistent and reliable suction: Designed to provide more stable performance than typical wall suction, which can vary due to kinks, shared vacuum sources, or calibration issues. Fast visualization clearance: Evacuates fluid and debris efficiently to quickly clear the surgical field. SmartSuction technology: Detects air in the line and automatically modulates vacuum force, so suction becomes gentler when skimming shallow pools of blood and air. This helps preserve RBCs for autotransfusion. Typical Operational Specs While features and exact numbers vary by region and model, in practice the system typically delivers: Maximum vacuum force: ~-150 mmHg (varies with air-to-fluid ratio) Free air flow rate: up to ~40 L/min Fluid flow rate: up to ~4 L/min Portable design: Intended as a dedicated, standalone unit used with Haemonetics autotransfusion systems (e.g., Cell Saver®5/5 and OrthoPAT® systems) without relying on hospital wall suction. Typical Clinical Benefits Helps preserve red blood cells for reinfusion during autotransfusion procedures by minimizing hemolysis. Improves suction stability and visualization in surgical environments. More controlled and predictable suction compared with standard wall vacuum sources.
