Abstract
An interactive enthalpy exchange system for infant care includes a pouch for receiving an infant, and a heat source arranged in the pouch. The heat source includes a first heat source and a second heat source different from the first heat source. Control circuitry is operatively coupled to the heat source, the control circuitry configured to control interactive enthalpy between the first heat source and the second heat source to maintain a temperature within the pouch at a prescribed temperature.
Claims22
An interactive enthalpy exchange system for infant care comprising:
- a pouch configured as a wrap, wherein the pouch is wrappable around an infant;
- a temperature sensor for measuring a skin temperature of the infant;
- a heat source arranged in the pouch, the heat source including a first heat source and a second heat source different from the first heat source;
- and
- control circuitry operatively coupled to the heat source, the control circuitry configured to control interactive enthalpy between the first heat source and the second heat source to maintain a temperature within the pouch at a prescribed temperature, the control circuitry further configured to control an amount of power provided to the heat source based on the skin temperature measured by the temperature sensor, wherein the control circuitry is configured to provide uniform heat transfer by conduction to the infant placed in the pouch by exchanging enthalpy among the heat sources based on a temperature outside the pouch.
A method for providing uniform thermal energy to an infant using an interactive enthalpy exchange system having a pouch configured as a wrap, wherein the pouch is wrappable around the infant, a heating device having a first heat source and a second heat source different from the first heat source, and control circuitry operatively coupled to the heating device, the method comprising:
- measuring a skin temperature of the infant;
- monitoring at least one of i) the measured skin temperature of the infant within the pouch, ii) a temperature external to the pouch, iii) a temperature of the first heat source, and iv) a temperature of the second heat source;
- and
- controlling enthalpy exchange between the first and second heat sources based on at least one of the measured skin temperature of the infant, the temperature of the first heat source, the temperature of the second heat source and the temperature external to the pouch to provide heat to the infant, said controlling including controlling an amount of power provided to the heating device based on the measured skin temperature;
- wherein controlling enthalpy exchange includes providing non-uniform thermal energy to the infant via enthalpy exchange between the first and second heat sources based on at least one of the skin temperature of the infant, the temperature of the first heat source, the temperature of the second heat source and the temperature external to the pouch, and wherein non-uniform thermal energy is provided selectively, depending on proximity of the pouch to an area of the infant;
- measuring an ambient temperature outside the pouch;
- and
- adjusting a duty cycle of power provided to the heating device based on the measured ambient temperature.
