Abstract

The present invention generally relates to infant warmer or incubator and more particularly to a technique to provide warm environment to infants and air conditioning to staff and mothers at the same time. The technique transfers latent heat and sensible heat from the atmospheric air into an infant compartment. The technique is for infant warmer or incubator that includes a heat pump to transfer latent and sensible heat from the atmospheric air into an infant compartment to maintain a desired air temperature inside. The technique uses a vapor compression heat pump to extract freely and abundantly available sensible and latent heat in atmospheric air throughout the day. The pump extracts heat even during night hours. The pump then directs the extracted heat into an infant compartment to keep infants warm.

INFANT CARE APPARATUS

FIELD OF INVENTION

The present invention generally relates to infant warmer or incubator and more particularly to a technique to provide warm environment to infants and air conditioning to staff and mothers.

BACKGROUND OF THE INVENTION

In general, a large percentage of population lives in tropical regions in the world where most part of the climate is warm and humid. Excessive heat discomforts people living in that environment, which are dealt with the use of air-cooling or air conditioning systems. Infant care facilities located in these regions encounter-contradicting requirements of keeping infants warm with the help of infant warmers or incubators. Whereas, recuperating mothers and other hospital staff requires air cooling or conditioning to be comfortable. Many facilities have air conditioners fitted to improve the comfort for the mothers and nursing staff where infant warmers are operated in the same environment. A typical infant warmer draws significant electric power to operate resistive heating element that adds proportional amount of cooling load to the air conditioning system besides consuming a huge power by itself making the whole solution very energy intensive. In infant care facilities which lacks in any suitable air cooling or conditioning facilities, a large amount of heat released from the infant warmer heats up the room air making the room uncomfortable for the recuperating mothers and the nursing staff. The availability of continuous power is not assured because of frequent and long duration of power outages. Therefore, these devices operate on battery back-up or on portable generators. Further, high surface temperatures of resistive heating elements pose fire hazards. Dust and debris settled on the surface of heating elements are prone to getting ignited and fall on the mattress leading to fire particularly in radiant warmer which are poorly designed and built. Also the overhead radiant warmers are also prone to accident which results in burn injuries to caregivers. FIG. 1 depicts hospital environment at two different locations.

Therefore there is a need in the art for a technique to provide warm environment to infants and air conditioning to staff and mothers.
