Introduction to Medical Wiring Harness
Medical wiring harnesses are connection components designed specifically for medical equipment and need to meet high safety and stability requirements.
Definition and core functions
Functional positioning: used in medical scenarios such as monitors, surgical instruments, and imaging equipment to ensure the accuracy and continuity of device signal transmission.
Safety requirements: must pass rigorous tests such as high voltage, heat resistance, and corrosion resistance to ensure zero-error operation and avoid medical accidents
Material characteristics
Conductor and insulation layer: Made of medical grade silicone, fluororubber or TPE materials, it has flexibility, high temperature resistance (can withstand ≥ 85 ℃) and biocompatibility.
Connector: Metal contacts are gold-plated to reduce signal loss and enhance oxidation resistance.
Process standards
Sealing: The key interface adopts injection molding or epoxy resin sealing process to prevent liquid penetration and cross contamination.
Sterilization compatibility: Must withstand repeated treatment with high temperature steam, ultraviolet radiation, or chemical disinfectants.
The difference between medical wiring harness and ordinary wiring harness
| Dimension | Medical wiring harness | Ordinary wiring harness |
| Material safety | Compliant with ISO 10993 biocompatibility standard, non-toxic and harmless | Emphasis on universality, no mandatory biosafety requirements |
| Environmental tolerance | Resistant to high temperature disinfection and chemical corrosion (such as alcohol and glutaraldehyde) | Only suitable for regular temperature and humidity environments |
| Certification standards | Require FDA, CE medical certification, and industry standards such as YY/T 0691 | Compliant with general electrical safety standards (such as IEC) |
The wires used in medical wire harnesses are all high-quality wires that have met certification standards such as UL, VDE, CCC, and JIS. Commonly used medical connectors include wire-to-board connectors, D-SUB connectors, pin headers and socket headers, and aviation plugs. The connector brands typically used are international ones like TE, Molex, and Amphenol. System certification generally follows the 13485 medical standard, and most materials also need to meet sterilization requirements. Thus, new entrepreneurs planning to enter this industry must be aware of the thresholds and requirements for medical wire harnesses.
Given the high-risk and high-precision nature of the medical industry, the standards for medical devices differ from those of general devices. Just in terms of standard strictness, the inspection standards for medical devices are the most rigorous. Common wire harnesses, power cords, FPC, FFC, and drive-screen wire harnesses (LVDS) are extensively used in the connection of medical equipment.
