bili-hut™at the bedside
In the hospital
High-intensity phototherapy at the bedside, in postpartum and outpatient units — without separating babies from their parents.
At home
Portable and family-centered, bili-hut™ supports home phototherapy programs with home-care and DME partners.
And beyond
If it works in the jungle, it works anywhere.
bili-hut™ runs on very little power — including solar panels and battery packs — so effective phototherapy reaches places where conventional equipment can’t go, from remote clinics in Papua New Guinea to Peru and Africa.
