Patient monitors, ventilators, ultrasound, CT — medical harnesses carry patient safety. The barrier is not making them, but making every step compliant.
1. The IEC 60601 framework
IEC 60601-1 and its collateral standards govern leakage, insulation and creepage; select wire (UL94 V-0) and routing from the machine's certification target backward.
2. Patient-contact parts: biocompatible, disinfectable
Patient-contact leadwires need biocompatible, hypoallergenic jackets that survive alcohol wipes; smooth jacket surfaces resist pathogens.
3. Signal quality: guarding weak physiological signals
ECG signals are millivolt-level; shielding and twist pitch decide waveform purity, and low-noise designs need system-level verification.
4. Reliability and traceability
Devices live 10+ years; verify flex life for cart and boom movement, and keep full lot traceability and inspection records for audits.
