Abstract: The present invention provides an enclosed humidified environment for an infant positioned on the mattress of an infant warmer open care bed. It includes an “A” frame structure which supports a flexible and transparent cover similar to a tent, which may be folded substantially flat when not in use or prior to use. The tent is designed to be compatible with an infra-red radiant heater, such as might be used in a infant warmer open care bed to heat the infant. The tent includes provisions for inflow of humidified gases and accessibility to the infant by health care workers. In addition, the present invention may be provided as a disposable item thereby reducing the possibility of transferring medical problems between infants.
