The modern medical environment relies heavily on advanced medical devices to deliver the appropriate diagnosis and the appropriate intervention. In this case, all components must work together to ensure patient safety. The medical cable is one of the most important elements of such a complicated assembly that is often concealed behind the sophisticated software and equipment. As it connects sensors, displays, and processing units, the medical cable must operate reliably without failure. Hotten specializes in fine wire technology with a strong commitment to quality, and also provides medical cable products that provide safe and dependable life-critical devices.
Unlike a typical commercial cable, a medical cable ought to meet high standards of regulatory requirements, withstand repeated sterilization, be resistant to chemicals and still maintain electrical performance under continuous flexing. The medical cable solutions being provided by Hotten such as ultrasound probe, endoscope, ICE, IVUS, dental sensing, RF ablation, EEG lead wires and surgical scalpel cable is meant to align with the fastidious requirements needed to ensure consistent operation of the very vital medical devices.
Patient protection requires electrical safety The conditions under which medical devices are operated usually expose patients to potential leakage currents, especially when devices are in direct contact with the body. This is the reason why the medical cables should ensure satisfactory electrical isolation, ground support and international safety standards (IEC 60601).
The medical cables are designed to be made at Hotten with high dielectric materials and specially designed shielding to minimize leakage currents to the lowest possible level and eliminate undesirable electrical paths. Through inspection of homogeneity of the insulation thickness and correct positioning of the conductors of our production, we will be able to minimize the risks of a short circuit and extend the working life of our medical cables. Hotten ensures electrical safety throughout design and production.
Medical devices require the ability to be used diagnostically, which can only be made possible through the clarity of the signal. The cables of ultrasound probes, such as ultrasound transducer cables, must be able to pass the high-frequency echo signal of the transducer to the processing unit without excessive attenuation or signal interference. EEG lead wires should have the capability of detecting microvolt-sized neurological signals. Signal degradation may lead to false readings or missed diagnoses
The LVDS wire harnesses, RF cables and custom coaxial assemblies designed by Hotten are designed to preserve the signal integrity over the required cable length. A combination of impedance selection and a cable design in the form of a two-wire cable, with multi-layered shielding, reduces potential interference by nearby equipment (i.e. MRI machines, power supplies and wireless equipment), and guarantee a clean and proper signal to the display or processor. Such an assurance is what a clinician requires in order to make real time decisions about important health issues.
Medical cables should have the capacity to withstand a significant amount of physical stress. The bending, coiling and extensive manipulation which ultrasound probes go through on a daily basis would destroy most normal cables, and the endoscope cables would be damaged by being passed through twisting routes. Surgical cables and probes are also supposed to withstand the sterilization processes that can be in form of autoclaving, hydrogen peroxide plasma or chemical disinfection depending on the necessity.
Hotten engineering can address these challenges through choice of strong materials and application of cautious construction methodologies. The medical cables of Hotten provide both powerful strain relief of their connector interface and an elastic but tough jacketing material that is capable of resisting the usual medical detergents. The conductor design is optimized for high flex life to assure the continuity of signals and signal integrity through many operating cycles. Our engineers also come up with over 300 different cable designs each year, and this also adds to the fact that our medical cables can withstand thousands of applications with the best mechanical integrity.
The sterile conditions of the area occupied by the medical devices, and any other section of the device that directly touches the patient, require the use of cables that are resistant to sterilization procedures. Depending on the purpose of use, devices can be put through steam autoclave, ethylene oxide (EtO), gamma sterilization or chemical disinfection. All these processes create various types of stress on the physical structure of a cable and may lead to embrittlement or shape deformation.
The engineering department at Hotten picks up materials, which have a good compatibility with most of the sterilization equipment. Moreover, in the cases when the interaction with the patient is inevitable, Hotten applies the biocompatible materials, in accordance with the ISO 10993 requirements to guarantee the safety of patients and the quality of the device and electronics.
The high number of medical uses implies that there must be as many medical cable solutions as there are medical uses. Exceptional flexibility needs to be made in an ultrasound probe cable in order to allow movement, without interruption of electrical connections; RF ablation cables need to conduct energy efficiently and without distortion; EEG lead wires should have the lowest signal-to-noise ratios.
Medical cables are much more than an interconnection; they are an essential part which is required to ensure the safe and reliable functioning of medical devices. Through the stringent quality assurance and design of our medical cables, Hotten enables the services of health care providers to be performed with appropriate assurance that their equipment performs properly, provides adequate electrical safety and signal integrity, is mechanically sound, and can be able to be used in sterile environments.
With the ever-growing technological development and the evolution of the medical sphere, the need in the strong interconnection solutions is going to only grow. Hotten still concentrates on the skills required to supply the medical cables required at the forefront of innovation whilst upholding the highest possible rates of performance and safety since in healthcare, performance is never optional
