The LymphoDrain CX-3 is a semi-rigid wearable sleeve — available in full-arm, full-leg, and torso-panel configurations — that uses a network of micro-pneumatic chambers and piezoelectric compression nodes to mechanically stimulate lymphatic drainage in patients with compromised lymphatic function. Originally designed for long-term augmentation patients whose lymphatic vessels were disrupted during implant installation, the CX-3 mimics the natural peristaltic rhythm of healthy lymphatic tissue at programmable intervals, preventing the edema and immune-suppression cascade that frequently follows major cybernetic integration surgery.

The sleeve's inner lining incorporates a bioelectric feedback layer sourced from Zheng-Dao Bioelectric's flexible conductor technology, allowing it to detect subcutaneous fluid accumulation in real time and adjust compression sequencing accordingly. A companion application running on any Saltmarsh-compatible personal device displays lymphatic flow metrics and flags early signs of infection or implant-site rejection. Higher-tier versions include a pharmaceutical delivery reservoir that can inject micro-doses of anti-inflammatory compounds directly into lymphatic vessels during compression cycles, eliminating the need for systemic medication.

In clinical settings, the CX-3 is prescribed as a mandatory recovery device following any Tier 1 or Tier 2 augmentation procedure involving thoracic or limb implants. In the streets, it has found a second life as a performance device — long-haul courier workers and manual laborers in Palladian construction sites use unauthorized units to manage chronic limb swelling from repetitive strain, and combat-augmented mercenaries wear them during downtime to accelerate recovery from trauma edema. The street nickname 'Milker' is considered derogatory by long-term medical users but has been enthusiastically adopted by the merc community.
