BiWaze Cough Assist System — Certified Pre‑Owned (CPO)

Dual‑blower MI‑E therapy with oscillation, lung expansion, and portable battery power.

The BiWaze Cough Assist System is a modern mechanical insufflation–exsufflation (MI‑E) system that simulates a natural cough to clear bronchopulmonary secretions. Each therapy cycle delivers a positive‑pressure inhale, a rapid switch to negative‑pressure exhale, and a pause (with optional positive pause pressure) to keep airways open between cycles.

Unlike single‑blower systems, BiWaze uses two separate blowers (one for inhale, one for exhale) to keep flows distinct — a hygienic approach that helps maintain consistent therapy delivery. You can add oscillations (HFO) to loosen mucus, combine lung‑expansion with cough therapy, and tailor cycles using Auto or Manual control.

For mobility, the system offers an internal lithium‑ion battery: up to ~2 hours of active therapy per full charge; ~4 h 15 m to recharge; and pass‑through charging while on AC power.

Is a refurbished unit safe and reliable?

Yes. Each CPO unit is inspected, tested and certified to deliver therapy within spec; wear items are replaced as needed. (Prescription use.)

It combines MI‑E + lung expansion + oscillation and uses dual blowers to separate inhale/exhale paths for hygiene and consistency.

What’s the battery runtime?

Up to ~2 hours of active therapy; about 4 h 15 m to recharge; it charges while on AC.

Which patient circuits can I use?

Standard 22 mm kit or the BiWaze coaxial dual‑channel set. Your clinician will specify the interface (mask, mouthpiece, or trach).
