Appl. No.:

09/534235

Inventors:

Joseph J. Lessard - Horsham PA
Robert M. McDonough - Hatfield PA
Jan F. Wenstrup - Doylestown PA
Peter Schumann - Richboro PA

Assignee:

Hill-Rom Services, Inc. - Batesville IN

International Classification:

A01K 3120

US Classification:

237 3, 237 14, 454195

Abstract:

An infant incubator in which the heater for heating the air circulated through the incubator and the speed of the fan which forces air across the heater to circulate through the incubator are controlled to increase the temperature of the heated air and delivery of the heated air to the space in which an infant has been placed for treatment when an access door of the incubator has been opened. The increase in temperature and delivery of the heated air is caused by a sensor which senses when the access door is opened.
