incubator

The invention relates to an incubator, the'inspecially for transporting small children, e.g. premature births or children born unexpectedly ^ in a hospital

is. ν.

The object of the invention is a portable incubator in which the toddler is protected against the many harmful influences that arise when the incubator is transported by means of an automobile or ambulance. The incubator should, for example, be designed in such a way that the toddler lies securely and quietly in the cot located inside the incubator when inertial forces inevitably act on the incubator when the ambulance accelerates rapidly or when cornering. Furthermore, devices are to be provided on the incubator with which the atmosphere inside the incubator can be kept at a preselected temperature, even if the outside temperature fluctuates within wide limits, as occurs when the incubator is transported, especially in winter or in regions with cold temperatures Climate where outside temperatures are -18 ⁰ C (O ⁰ I ' ¹ ) or less is unavoidable.

The incubator according to the invention should also be one in itself have a closed fresh air system, so that the toddler sufficient quantities of fresh air and / or oxygen can be supplied during transport. Furthermore, an air humidification system should be installed be provided, which also by
