Otter Newborn Warmer

In Progress



Each year over 4M infants in developing countries die within a month of birth due to complications of prematurity, low birth weight and infection. We could prevent more than 1.3M of these deaths by providing at-risk newborns with a warm and clean environment in which to grow stronger. Conventional newborn incubators are complex, expensive to own and operate and difficult to keep clean.


Otter is a durable, washable warming bassinet for premature and low birthweight (LBW) newborns. A single-newborn warming mattress that supplies steady warming at body temperature, Otter will eliminate the risk of hypothermia and reduce the incidence of hospital-acquired infection. Otter is also small and portable. It can accompany newborns on the trip from the delivery room to the neonatal ICU. Otter will work as a stand-alone device and as a complement to both DtM’s Firefly and to conventional overhead phototherapy devices. To facilitate adoption, the device will comply with existing international standards for conductive newborn warming devices.


We have completed market analysis, including surveys of existing warming devices for newborns. We will pursue manufacture through technology licensing agreements with multinational medical device companies targeting LMIC markets who have already expressed interest in this project. 

Otter is designed to be:

  • Hard to use wrong - simple “plug and play” user interface automatically sets a safe and effective surface temperature, with simple indicators for “ready” vs “not ready” and “functioning” vs “not working”.  Bassinet only fits a single term newborn, in order to reduce the incidence of cross-infection from newborns sharing beds.
  • Simple to clean - a modern incubator can take up to 45 minutes to clean properly given all of the internal seams and crevices; Otter has a smooth, seamless interior that can be wiped clean with alcohol in just minutes.
  • Complementary with Kangaroo Mother Care (KMC) - Otter maintains the temperature of newborns who cannot be thermoregulated using kangaroo mother care (KMC) because they are in the neonatal intensive care unit (NICU) for observation or treatment, for example receiving phototherapy from Firefly
  • Compatible with Firefly and Overhead Phototherapy - All newborns receiving phototherapy are vulnerable to hypothermia, so Otter is designed to work with both the Firefly Phototherapy device and with conventional overhead phototherapy devices like the GE Lullaby and D-Rev’s Brilliance.
