Publication number: 20150073516Abstract: The present invention provides a low-cost, low-power therapeutic hypothermia device for use in developing nations. The device includes a first and second receptacle separated by a space filled with a porous material such as sand. A cooling chemical can also be added to the porous material in order to speed cooling. Water is added to the porous material and a neonate is placed into the device for therapeutic hypothermia treatment. The neonate is monitored carefully using temperature sensors and a feedback system integrated into the device. Cooling can be modulated and/or warming commenced by adding Styrofoam blocks to raise the neonate off the surface of the device.Type: ApplicationFiled: April 9, 2013Publication date: March 12, 2015Applicant: THE JOHNS HOPKINS UNIVERSITYInventors: Soumyadipta Acharya, Robert Allen, Winston J.
