Medical cable also named medical grade cable, mainly refers to a custom medical cable used for medical equipment for patient operation, treatment, ambulance and monitoring. It can be divided into: blood transfusion grade, invasive surgery, non-invasive monitoring, internal use of medical equipment, etc, according to the medical grade used. Different use grades requires different materials.
Custom medical cable assemblies used in medical equipment should comply with ROHS requirements, Pb<10ppm, Cd<5ppm, do not contain phthalates and with good reliability. Except the above requirements, medical wires which used for medical non-invasive monitoring should also consider the product's abrasion resistance, pull resistance and other external effects, resistance to corrosion by commonly used medical disinfection solvents, and pass certain biological toxicity tests and skin allergy tests. There are also certain requirements for bending, voltage resistance and anti-interference.
UL CABLE Technology Co., Ltd is a medical cable manufacturer located in Dongguan city of China. We specialized in developing and manufacturing medical cable and other cables, such as automotive primary cable, UL cable , Towline cable, etc.
Composition of The Medical Wire
Medical wire and cable are composed of four parts: conductor, insulation layer, shielding layer and protective layer. Medical wire conductor is the conductive part of the wire and cable, used to transmit electric energy, and is the main part of the wire and cable. Medical wire insulating layer is to electrically isolate the conductor from the ground and the conductors of different phases from each other to ensure the transmission of electric energy. It is an indispensable part of the wire and cable structure. Medical Wires and cables with a shielding layer of 15KV and above generally have a conductor shielding layer and an insulating shielding layer. The role of the protective layer is to protect the wires and cables from the intrusion of external impurities and moisture, and to prevent external forces from directly damaging the power cables.
Characteristics of Medical Cables
As it’s special useage, medical wires and cables needs to have these characteristics, such as halogen-free, non-toxic, good bendability, resistance to torsion and pull, good airtightness, long service life, anti-aging, and strong anti-interference ability.
Types of Medical Cable
According to different medical equipment, medical cable can be divided into : ECG cable, blood transmission cable, scalpel cable ultrasonographic cable egastroscope cable, SPO2 cable, temperature measurement cable, monitor cable and so on. According to the frequency of use. The overall requirements of medical cables are summarized as follows:
Requirements on Medical Grade Cable
Make patient comfort: soft and flexible, low friction resistance, smooth and round appearance.
Ergonomics: Small size, light weight, high flexibility, intuitive and safe.
Sterilization requirements: suitable for EtO (ethylene oxide), high-pressure sterilization, low temperature treatment, CIDEX (glutaraldehyde) soak, IPA (isopropyl alcohol) wipe, etc.
Durability: Elasticity and reliability, wear resistance, resistance to sharp stretching, scratch resistance, torsion resistance, etc.
Electrical performance requirements: resistance, capacitance requirements, electromagnetic compatibility (RFI/EMI), voltage resistance, noise test, etc.
Economic benefit: The cost requirements of the product are different , according to the different times of use.
Advantage of Medical Cable and Wire
Medical wire and cable use green insulation, sheath and special oxygen barrier materials, which not only have good electrical and physical and mechanical properties, but also ensure that the product does not contain halogen and solves the problem of burning the formed "secondary pollution". It also avoids carcinogenic "dioxin" substances produced when traditional PVC wires are burned.
The environmental cable fully guarantees its building for fire prevention, medical cable is not easy to burn during a fire, and can prevent the spread of flame and the expansion of disasters after burning.
Medical wire insulation and sheath do not contain lead, cadmium and other heavy metals which harmful to the human body, and will not pollute the soil and water when medical wire and cable is used and discarded.
Medical wire use new special coating materials that are non-polluting to the environment , and no toxic gas such as HCL is generated during production, use and combustion. Medical wire emission of acid gas is very small, which causes little damage to personnel, equipment, and instruments. More environmentally friendly features.
Green materials with special molecular structure are used to ensure ultra-low water absorption. The special ultraviolet makes the product have good anti-ultraviolet function. Ensure the safety.
Application of Medical Wire
Medical wire is widely used in SPO2 sensor, EEG ECG monitoring, blood pressure testing, electrosurgical pen(disposable, repetitive) resistant to R radiation, steam sterilization,body temperature ,high-pressure health physiotherapy, nerve treatment, fetal supervision and contraction equipment.
