Whether installing the medical cable personally or by a professional power cable company, follow the installation precautions during the installation of the medical cable to ensure personal safety. Numerous medical devices rely on interconnecting devices such as cables, but unlike cables used in communication networks, medical cables have unique technical requirements. Medical cables must be extremely flexible, withstand repeated flexing, and must meet strict regulatory safety guidelines.
Ⅰ. Precautions for the installation of medical cables
1. The distance of 0.5m should be maintained when the medical cable is installed in parallel or crosswise with other pipes. When the medical equipment cable is directly buried, the direct buried depth of the 1-35kV cable should not be less than 0.7m. When the medical cables of 10kV and below are installed in parallel, the clear distance from each other is not less than 0.1m, and the distance between 10-35kV is not less than 0.25m, and the distance when they cross is not less than 0.5m.
2. The minimum bending radius of the medical cable, the multi-core cable shall not be less than 15D, the single-core cable shall not be less than 20D (D is the outer diameter of the cable), and the cable joint of 6kv and above.
3. The end of the medical cable must be waterproof and eroded by other corrosive materials to prevent breakdown due to the aging of the insulation layer caused by water trees.
4. Cranes or forklifts must be used for loading and unloading medical cables. Horizontal transportation and laying are prohibited. When installing large cables, a cable car must be used to prevent the cables from being damaged by external forces or scratching the insulation layer due to manual dragging. If it cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight exposure and water entering the cable end.
The above are the precautions for the installation of medical cables. When laying medical cables, a safety officer should be appointed to be responsible for the safety of the whole process of cable laying. For the cable laying project, a special on-site commander shall be assigned to conduct unified command and dispatch of cable laying.
Ⅱ. Requirements for the use of medical cables
1. Ergonomics: Small size, light weight, high flexibility, intuitive and safe.
2. Strive for patient comfort: soft and flexible, low friction resistance, smooth and round appearance.
3. Durable: elasticity and reliability, wear resistance, sharp stretching resistance, scratch resistance, torsion resistance, etc.
4. Sterilization requirements; suitable for EtO (ethylene oxide), high pressure disinfection, low temperature treatment, CIDEX (glutaraldehyde) soaking, IPA (isopropyl alcohol) wiping, etc.
5. Electrical performance requirements: resistance, capacitance requirements, electromagnetic compatibility, withstand voltage, noise testing, etc.
The medical industry is a harsh application environment for cables, and there are many factors to consider. In addition, due to the continuous innovation of technology in this field, it is also required that the development of medical equipment cables can keep up with the corresponding technical requirements at the same time.
