نحوه انتخاب کابل تجهیزات پزشکی مناسب?

It is necessary to combine these points and give a structured answer. به عنوان مثال, there are several major points: equipment compatibility, materials and structure, application scenarios, safety certification and maintenance, OTC.
How to choose the right medical equipment cable requires comprehensive equipment characteristics, usage scenarios and industry standards, and decisions can be made from the following dimensions:

1. Equipment compatibility requirements
‌Model matching‌
It is necessary to confirm that the harness interface is fully compatible with the physical specifications of the medical device, for example, the blood oxygen probe of the monitor needs to match standard connectors such as GH1.5 or M12;
Monitors of different brands (such as Mindray, GE) may have different harness protocols, and the compatibility list provided by the manufacturer needs to be checked1.
‌Signal transmission requirements‌
High-frequency equipment (such as laser surgical instruments) needs to use wires with excellent shielding performance (such as tinned copper wire + لایه محافظ فلزی) to reduce electromagnetic interference;
Precision instruments (such as ECG) need to control the stability of harness impedance to avoid signal attenuation.
Safety Standards:
Ensure the cable complies with relevant standards like IEC 60601-1, which covers safety requirements for medical electrical equipment. Look for certifications like UL, CSA, and IEC.
Cable Type:
Determine if you need a power cord, a signal cable, or a data cable.
نوع رابط:
Choose connectors that are compatible with the equipment and meet the required durability and safety standards, such as those with high mating cycle ratings.
Jacket Material:
Select a jacket material that provides adequate protection, انعطاف پذیری, and resistance to sterilization processes.
محافظ:
Consider the need for shielding to prevent electromagnetic interference (EMI) that could disrupt the performance of sensitive medical equipment.
دوام:
Evaluate the cable’s ability to withstand repeated flexing, sterilization cycles, and exposure to chemicals and moisture.
Ergonomics:
Consider the tactile feel and flexibility of the cable for ease of use.
Flexibility:
For applications where the cable will be flexed frequently, choose a cable with a flexible jacket and appropriately stranded conductors.
Current and Voltage:
Ensure the cable can handle the current and voltage requirements of the device.
طول:
Choose the appropriate cable length to minimize voltage drop and ensure sufficient reach.
Future Expansion:
Consider the potential for future upgrades and select a cable with sufficient capacity to accommodate them.

سوم. Application scenario adaptation
‌Diagnostic/therapeutic equipment‌
The endoscope harness needs to have a diameter of ≤3mm and be resistant to bending, and is suitable for miniaturized instrument channels;
The hemodialysis machine harness needs to withstand repeated disinfection (ethylene oxide/high-temperature steam), and it is recommended to choose a TPE outer layer material.
‌Monitoring and portable equipment‌
The wearable device harness needs to weigh ≤20g/m, and use an ultra-soft silicone outer layer to improve wearing comfort;
The neonatal monitoring harness must comply with the ISO 10993 biocompatibility standard to avoid skin allergies.

من. Safety certification and maintenance
‌Mandatory certification‌
Must pass ISO 13485 quality management system certification, and the wiring harness that contacts the human body must comply with the YY/T 0466 استاندارد;
Export products must meet the RoHS/REACH environmental directive, and some countries require UL certification.
‌Maintenance strategy‌
It is recommended to test the insulation resistance of high-frequency wiring harnesses (such as operating room equipment) every 3 months (standard ≥100MΩ);
The connector contact points need to be cleaned regularly with anhydrous ethanol to prevent oxidation from causing signal distortion.

حرفهای. Supplier screening suggestions
‌Customization capability‌: Prioritize companies that support reverse development of drawings, such as Yongrui Electronics, which can provide precision welding services for endoscope wiring harnesses;
‌Testing system‌: Check whether the supplier has full-process testing equipment (such as withstand voltage testers, bending testers);
‌Delivery cycle‌: Emergency equipment wiring harnesses need to select manufacturers with 48-hour expedited production capabilities, and the regular order cycle is ≤15 days.

یادداشت: Before purchasing, you should request samples for compatibility testing, focusing on verifying signal transmission stability and mechanical durability indicators.
