The fast paced environment demands mobility, portability to meet the challenges of the rising world. With the evolution of smart phones, an increase in smart gadgets have been observed. The medical industry has steadily trended toward improved portability of monitoring devices used in ambulatory patient care. In addition to boasting smaller footprints, many newer medical devices incorporate capacitive and mechanical touch pads, vibrant LED displays, and other technological advances first pioneered in consumer electronics. Worn continuously during normal activities, ambulatory monitoring devices make it possible for many patients requiring continuous monitoring of vital signs to leave the confines of a hospital or other clinical setting.
Monitoring cable design and performance reflect on the quality and performance of the monitoring device. Tremendous design and manufacturing resources are directed toward developing new monitoring technologies that will help people stay healthy and active. Those sophisticated devices can be rendered useless by a poorly designed or low quality cable assembly that results in intermittent operation or equipment failure. When engineering monitoring cables for medical monitoring devices, a number of factors must be considered to protect the patient and equipment.
Miniaturization Using Monitoring Cables
Due to the miniaturization of electronics, portable devices can now perform both patient monitoring and diagnostic ECGs while the patient is fully mobile. Devices the size of a mobile phone can now do the type of monitoring that was once carried out by large stationery monitors commonly found in a hospital setting.
Monitoring Cable Design
All of this could not be made possible if there the design of monitoring cables could not be evolved. As the size and bulk of cables used for medical devices decrease, the design must be carefully considered to prevent any loss of mechanical or electrical performance. The cable assembly must still be durable and deliver a service life consistent with the medical device to which it will be attached, while still meeting all safety and regulatory requirements. The right technologies make it possible to design a thin, flexible, lightweight medical device cable assembly with optimal mechanical performance and rugged construction.
A customized hybrid assembly for an ambulatory patient monitoring device features a strain relief bend to provide secure mating and a durable transition from the flexible cable to the over-molded connector. Portable consumer devices typically come equipped with thin, flexible cable assemblies for power and signal connectivity.
