Compression System Coretech (8-Chamber)

The Vive Health Coretech RHB3003 8-Chamber Compression System is a prescription-only pneumatic compression therapy device that uses sequential compression technology to support lymphatic drainage and circulation for people with lymphedema and related vascular conditions. It pairs a pump with 8-chamber leg sleeves that create graduated pressure patterns to help move excess lymphatic fluid from affected areas toward healthy regions where the body can process it naturally.

An included air adapter supports treating one leg, both legs at once, or a leg and an arm in a single session. Peristaltic Mode A and Sequential Gradient Mode B each produce a distinct compression pattern, with treatment times of 30, 45, or 60 minutes and pressure adjustable in 5 mmHg steps from 20 to 80 mmHg, while the patient safety lock prevents accidental changes during therapy.
