The heater assembly consists of a radiant heater, parabolic reflector, observation light,
and a visual alarm light. The parabolic reflector focuses radiant energy on the bed
surface, minimizing energy loss due to scattering and providing an even field of radiant
heat over the bed surface. The observation light provides intense light for procedures.
The alarm light is located on the end of the heater assembly for ease of viewing. The
entire heater assembly rotates to the side for X-ray procedures and for observation
lamp replacement.
1.4 Control Unit
The control unit contains the electronic circuits and controls used to operate the radiant
heater and the observation light. The control unit performs regular self checks during
its operation including failure diagnostics.
Either manual or servo mode of operation may be selected. In the manual mode of
operation, select the level of radiant heat output as indicated by the % power display
on the control panel. The control circuit then maintains the selected level of radiant
heat. The manual mode has a preheat setting which allows the Warmer to be pre-
heated. In the servo mode of operation, select the patient’s control temperature. A skin
temperature probe is used to monitor the patient skin temperature. The control system
modulates the radiant heat to maintain the patient at the selected control temperature.
The patient’s skin temperature is continuously displayed.
Alarms activate to alert the operator of a low or high patient temperature, a skin tem-
perature probe failure, a power failure, equipment failure or a check patient prompt.
1.5 Bed Platform
Warmers with beds include a mattress and transparent side panels. The side panels
fold down for easy access to the patient and can be removed for cleaning. The X-ray
cassette tray (located in an opening beneath the bed when installed) pulls out for
insertion of X-ray cassettes and allows X-rays to be taken without moving the patient.*
Markings located along the side panels allow easy location of the cassette in the X-ray
tray relative to the position of the patient on the warmer bed.* The tiltable bed platform
allows Trendelenburg and reverse Trendelenburg positioning. The hydraulic system for
the tiltable bed provides a smooth, dampened motion to avoid disturbing the patient.*
A chest drainage hanger attached to the bed and rear cross bar extrusion provides a
convenient location to hang chest drainage devices.*
1.6 Bassinet (3500 Series)
The bassinet unit can be detached and rolled away from the model 3500 warmer unit
by pulling up on the locking lever knob located at the top rear of the bassinet (see
Figure 1-1). The bassinet includes:
1. Transparent locking side panels which fold down for easy patient access and are
removable for cleaning.
* Not available on the model 3500 warmer.
