What is a Medical Wire Harness

　　A medical wire harness is a specialized cable assembly used in medical devices and healthcare equipment. It is typically composed of multiple fine conductors, insulation layers, and shielding structures, arranged and secured to ensure reliable power delivery and stable signal transmission. Its design focus goes beyond electrical performance, also addressing the strict safety, biocompatibility, and durability requirements of the medical industry.

Common Materials for Medical Wire Harnesses

　　1. Conductor: Highpurity oxygenfree copper or tinned copper, providing low resistance and excellent conductivity.

　　2. Insulation Layer: Medicalgrade PVC, PE, FEP, or silicone, offering nontoxicity, corrosion resistance, and hightemperature tolerance.

　　3. Shielding Layer: Aluminum foil or tinned copper braid, reducing electromagnetic interference and maintaining signal integrity.

　　4. Outer Jacket: Flexible medicalgrade silicone or TPU, resistant to disinfectants, bending fatigue, and aging.

Key Features of Medical Wire Harnesses

　　• High Reliability: Ensures lossless signal transmission in critical applications such as ECG monitors and ventilators.

　　• Sterilization Resistance: Withstands repeated steam autoclaving and chemical disinfection.

　　• Biocompatibility: Manufactured with medicalcompliant materials that do not release harmful substances.

　　• Flexibility and Durability: Designed for longterm bending and movement without conductor breakage.

　　• EMI Shielding: Multilayer shielding construction effectively suppresses external electromagnetic interference.

Applications of Medical Wire Harnesses

　　• Patient Monitoring: Used in ECG machines, monitoring systems, and ventilators for signal and power transfer.

　　• Imaging Systems: Connecting ultrasound probes, endoscopes, and other highprecision imaging devices.

　　• Surgical Instruments: Supplying stable energy to electrosurgical units, laser therapy equipment, and similar tools.

　　• Rehabilitation Devices: Applied in wearable rehabilitation systems for signal acquisition and data transmission.

Recommended Equipment: WG-9550 Wire Stripping Machine

　　In medical wire harness processing, insulation layers are usually thin and made of soft materials, requiring extremely high stripping precision.

　　The WG9550 Wire Stripping Machine provides the following advantages:

　　• HighPrecision Blades: Ideal for stripping finegauge and multicore medical wires without damaging conductors.

　　• Material Adaptability: Supports a wide range of insulation materials, including medical silicone and FEP.

　　• Automation Efficiency: Increases processing speed, ensures consistency, and reduces manual errors.

　　• Intelligent Adjustment: Automatically adapts stripping force according to wire diameter and sheath properties.

　　This makes it highly suitable for largescale production and processing of medical wire harnesses.
