The application solution for medical instrument cables focuses on meeting the stringent requirements of medical equipment for safety, reliability and adaptability to specific environments. The key points are as follows:
1. Safety Design
Electrical Safety: Use high-voltage-resistant insulating materials (such as with a voltage resistance of ≥ 4000VAC) to prevent the risk of electric leakage; the cross-sectional area of the conductors is matched with the power of the equipment to avoid overheating due to overload.
Mechanical protection: The outer sheath is made of wear-resistant and tear-resistant medical-grade materials (such as TPE, silicone rubber), and its durability is ensured through bending tests (such as ≥ 5000 times).
Biocompatibility: The parts in contact with patients must undergo tests for cytotoxicity and skin irritation. The material is non-toxic and harmless (such as free of phthalates).
2. Anti-interference Optimization
Shielding Structure: Utilize a "twisted pair + aluminum foil + woven mesh" composite shielding method to suppress electromagnetic interference (such as the attenuation of electrocardiogram monitoring cable ≥ 60dB).
Grounding design: Follow the single-point grounding principle to avoid ground loop interference and ensure the stability of signal transmission.
Low-magnetic material: The cables of MRI equipment use low-magnetic-conductivity materials such as silver-coated copper wires to prevent eddy current heating.
