Neonatal Cooler – MiraCradle®

MiraCradle® - Neonate Cooler is an affordable whole body cooling device for neonates or newborns suffering from Hypoxic Ischemic Encephalopathy due to birth asphyxia. MiraCradle can be used as a standalone solution or in combination with radiant warmer.  It uses the advanced savE® phase change material (PCM) technology to rapidly induce therapeutic hypothermia.


Did you know the characteristics of an ideal cooling device?

  • It should induce cooling rapidly to the desired core temperature.
  • It should maintain the core temperature tightly within the target range.
  • It should allow re-warming in a slow and controlled manner.
  • It should be easy to use.
  • It should require minimal nursing input.
  • It should not interfere with access to the baby.
  • Environmental temperature should not affect cooling efficacy.
  • Safety systems in case of accidental probe displacement.

Five benefits that MiraCradle offers:



Passive cooling system; does not have any electrical supply near the baby.


Easy to use

Minimal manual supervision required. PCMs can be charged in a normal refrigerator.


Long lasting

The PCMs are designed for repetitive use.



Gives precise temperature control.



Less than 1/5th of the cost of the available electronic devices.


MiraCradle® - Neonate Cooler

A cooling device to induce therapeutic hypothermia among newborns suffering from birth Hypoxic-Ischemic Encephalopathy (HIE).

MiraCradle consists of four main components:


It is a rotomolded plastic structure which serves as a framework for placing all the other components of MiraCradle®- Neonate Cooler and also provides insulation to the PCM helping it last for longer hours


This forms the bottom layer of the MiraCradle®-Neonate cooler. Three units of savE®FS-29 PCM are placed at the bottom of Cradle. savE®FS-29 in solid state passively extracts heat from the neonate’s body which is at 37°C thereby inducing and sustaining hypothermia.


This is the middle layer of the device.savE®FS-21 is used in conjunction with savE®FS - 29 to quickly bring the temperature of the neonate down to 33°C. It is subsequently removed and savE®FS – 29 takes over to sustain the temperature for longer hours.


The conduction mattress is a gel bed which provides a smooth surface for the baby to lie on and improves heat transfer between the baby and the PCM.

Phase Changing Material for Therapeutic Hypothermia in Neonates with Hypoxic Ischemic Encephalopathy – A Multi-centric Study Thomas at al,

Using phase changing material based cooling device and a standard protocol, it was feasible and safe to provide therapeutic hypothermia to asphyxiated neonates across different neonatal units in India. Maintenance of target temperature was comparable to standard servo-controlled equipment.

Phase Changing Material: An Alternative Method for Cooling Babies with Hypoxic Ischaemic Encephalopathy Thomas at al.

PCM provides a low cost and effective method to maintain therapeutic hypothermia. However, careful monitoring is required during induction and the rewarming phase to avoid hypothermia outside the therapeutic range.
