Medical cables are high-performance cables specifically designed for medical equipment, used to connect devices and sensors for transmitting power, signals, and data. Due to the stringent requirements for safety, reliability, and hygiene in medical applications, these cables must exhibit properties such as high insulation, sterilization resistance, flexibility, and biocompatibility. Below is a detailed overview:
Purpose: Designed for electrical connections in medical devices to ensure safe, reliable, and hygienic operation.
Applications:
Connects medical equipment (e.g., monitors, surgical devices, imaging systems) and sensors.
Key Fields:
Patient monitoring (e.g., ECG machines, blood pressure monitors).
Surgical equipment (e.g., electrosurgical units, laser devices).
Imaging systems (e.g., ultrasound, X-ray machines).
Medical robotics.
In-vitro diagnostic devices.
Medical cables feature specialized construction to meet high standards:
Conductor:
