Infant incubator with air curtain

Abstract

An infant incubator is disclosed having a hood that encloses the infant compartment. In the base of the incubator is the heating air and ducting means and which provides heated through an ever open outlet in the base and which heated air passes from the base through a flow path formed by the hood that circulates around the infant and re-enters the base through an inlet. That heated air is thus introduced into or along the access door in the front of the hood from the outlet and travels through or along the access door and through or along the hood around the infant and is returned to the base for recirculation. The hood itself is pivotally attached to the base at the rear of the incubator so that it can be opened from the front for complete access to the infant. The access door in the front of the hood is pivotally attached to the incubator base and can also be opened for access to the infant. When the access door is in its closed position, it forms part of the air path for the heated air. The heated air from the access door continues to pass along the flow path formed by the hood. When the access door is opened, it pivots out of the way of the air flow from the ever open outlet in the base and the flow of heated air continues over the area normally occupied by the access door when in its closed position forming an air curtain to protect the environment of the infant compartment. The flow of air thereafter enters the flow path formed by the hood in the same manner as the path of the air flow when the access door is closed and eventually re-enters the base through the inlet.
