This new patient cable answers a need for a robust, yet very Small profile cable for compact “Holter” type event recorders. Because the cable leads are attached to the patient and worn over a period of hours and days, this cable’s design must satisfy user’s comfort issues while insuring performance and reliable connectivity. This new five-lead cable features gold plated “no-touch” pins terminating color coded, shielded snap leads that are molded into a single, unitized Santoprene® plug. This polarized, 6-pin plug is designed with a unique passive locking mechanism for positive retention. This allows easy, error-proof insertion and extraction while retaining signal connectivity. The ANSI/AAMI EC-53 1995 Standard for ECG Cables and Leadwires and IEC60601-1 requirements are met by this new design.
