All models of the Ohmeda Medical Infant Warmer System provide a controlled
source of radiant heat for infants and pediatric patients. The control system uses
a microprocessor and provides both manual and servo modes of operation
(except for the 2001 International, which is manual mode only).
The model 2001 International has an integral infant bed and is a manual mode
only warmer designed for short term attended care in the OR and L&D.
The wall mounted 3050, 3100 and 3150 models are available to accommodate
specific architectural requirements in the NICU, L&D, LDR and LDRP room .
The 3050 is a heater head only, the 3100 is a heater and dove tail rails, and the
3150 includes a heater, rails and integral bed.
The model 3300 has an integral bed for infants and is intended for procedures
and long term care in the Nursery and L&D The model 3400 is the same as the
3300, except it has an elevating pedestal to raise and lower the bed .
The model 3000, 3500 and 4000 are free standing Warmers which can be used
over a variety of infant bassinets in the general nursery, over post-operative
patients, during patient feeding, and in any other application where controlled
radiant heat is required.
The 3500 System also has a detachable Bassinet for infants, and is intended for
procedures and long term care in the Nursery, L&D, LDR and LDRP Rooms.
