Introduction
Dayspring is a programmable, calibrated,
wearable active compression system designed to
stimulate the body’s lymphatic system and provide
you with mobility and portability while helping you
manage your chronic condition.
The system is comprised of a Controller and a
segmented Garment with multiple, programmable
compression segments. When properly used, the
Dayspring system creates a calibrated pressure
gradient and compresses sequentially in a wrist to
shoulder (distal to proximal) direction to help you
move and drain excess lymph uid.
Your Dayspring system comes with the following:
