The Edan SH5.DB9 (02.01.210121) is a medical-grade reusable pulse oximetry sensor engineered for optimal pediatric patient comfort during prolonged monitoring periods. Featuring a flexible, hypoallergenic silicone soft-tip boot, this specialized finger sensor contours gently around smaller patient digits to prevent friction sores while maintaining strict optical alignment for photometric tracking. Designed with a short 1-meter cable ending in a standard DB9 sub-D connection, this sensor is engineered to interface directly with vital signs configurations via an intermediate SpO2 extension or adapter cable to ensure steady oxygen saturation data stream transmission.
