Abstract

A method and system for thermal control of micro-environment of an infant support in the interior of an incubator is disclosed. The system senses difference conditions of micro-environment in the interior of the incubator and ambient conditions and activates air curtain by controlling fan speed accordingly. The system uses a temperature sensor or a velocity sensor or a combination thereof to sense the difference.

METHOD AND SYSTEM FOR THERMAL CONTROL OF AN INFANT SUPPORT

BACKGROUND

 

The present disclosure relates generally to infant incubators and more particularly to a method and system for thermal control of an infant support.

Generally, incubators are used to maintain appropriate body temperature of small or premature infants. An incubator provides a controlled and protective environment, within which heated air is circulated to minimize heat loss of the infant. Optimal temperature, humidity and other ambient conditions such as carbon dioxide and oxygen content are maintained inside the incubator. Heat is transferred to the infant via convective heat transfer. Various ports and doors are provided in the incubators to access the infant. However, when opened these ports and doors cause rapid cooling of the interior of the incubator. For maintaining consistent temperature in the interior of the incubator, conventional techniques employ an air circulation system with a heater and a motor driven blower is employed that provides an air curtain.

One conventional technique controls the circulation system based on temperature of the infant in the incubator. Another conventional control system facilitates thermal management by increasing air flow and infusing heat from a heat reservoir into the enclosure, when the incubator is in closed configuration. Yet another conventional technique involves increased heating and faster circulation of air in the incubator when the access door is opened. Opening of the access door is detected by a sensing means responsive to movement of the access door. However, these conventional techniques do not provide efficient thermal management of interior of the incubator and also have delayed response time to change in ambient conditions.

It would be desirable to have an improved and faster method and system for thermal control of an infant support.

DETAILED DESCRIPTION

A method and system for thermal control of micro-environment of an infant support in the interior of an incubator is disclosed. The system senses difference conditions of micro-environment in the interior of the incubator and ambient conditions and activates air curtain by controlling fan speed accordingly. The system uses a temperature sensor or a velocity sensor or a combination thereof to sense the difference.

According to one embodiment the system employs a temperature sensor. The temperature sensor may be a thermocouple or a thermistor. The temperature sensor is mounted on a hinge of at least one access door towards the interior or micro-environment of the incubator. The system senses and uses difference in t...
