Key Features of the DBI-DC12 Reusable SpO2 Sensor

Soft Tip Finger Sensor for Adults

The flexible soft tip wraps the finger without a rigid clip, reducing pressure points and helping to lower motion artefact in awake or restless adult patients.

Long Cable for Flexible Positioning

A 3.6 m lead lets clinicians position the monitor away from the bed, reducing cable strain and making patient repositioning easier.

Masimo Rainbow Connector

The red DCI-style 20-pin plug matches the Masimo Rainbow interface used on Radical-7, Rad-97 and Rad-57 devices.
