1.1 General The Ohmeda Medical PandaTM Baby Warmer provides 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. The patient temperature, control temperature, and elapsed time displays are digital for ease of viewing. The control panel includes a one hour elapsed timer with time displayed in minutes and seconds. The timer features optional audible tones for use during Apgar scoring. A complete audio and visual alarm system is included on the control panel.

1.2 Support Structure The support structure provides excellent stability for the radiant heater and optional accessories. On the free standing unit, the support structure consists of the base assembly and the uprights with an integral rail system. The rails provide a means for mounting accessories and ancillary equipment to the unit. Refer to Section 1.7 for a description of the accessory items.

1.3 Heater Assembly The warmer is designed to warm infants on a bed surface located beneath the heater assembly.

WARNING:

w Bed-to-heater spacing less than the recommended 64 cm will result in incorrect operation and may adversly affect the patient’s condition.

For your convenience, on the free standing unit the proper bed-to-heater spacing is indicated by a label located on the right aluminum upright (as viewed from the front). 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.

1/Description When the unit is first turned on, it automatically operates in the preheat mode, and will continue to do so until the mode, increase/decrease or Apgar buttons are pressed. Then a tone will prompt the operator to select a heater power percentage in the manual mode. 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. 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 temperature probe failure, a power failure, equipment failure or a check patient prompt.

1.5 Bed Platform The warmer with a bed includes a mattress and transparent side panels. The side panels fold down for easy access to the patient and can be removed for cleaning. 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.

1.6 Bassinet Two bassinets models are available for use with the free standing warmers. One with removabe drop side panels and mattress, and one with a removable tub. Transparent locking side panels fold down for easy patient access and are removable for cleaning. A tiltable lock block allows Trendelenburg and reverse Trendelenburg positioning at the 8° tilt position. Three drawers open from the side for storing equipment or supplies. The top drawer is provided with a key lock. Front casters lock to hold the bassinet in place.

1.7 Accessories The rail mounting system is the basis for most of the accessories for the Warmer. This patented design consists of a dovetail shaped aluminum extrusion and a positive locking mounting block. Mounting blocks are attached to various accessories for mounting to the rail system. The mounting blocks are produced in two standard lengths and are machined to accommodate each specific accessory. Accessories which mount on a single upright are interchangeable between all model Warmers. Accessories can only be mounted to the inside dovetail rail on each upright of the free standing warmer.

WARNING:

w Check for proper clearance above the Warmer and below the bed surface before raising or lowering the bed.

w Inspect all patient connected tubes or wires before and after moving or tilting the bed. Tilting or moving the warmer bed up or down can pull on tubing or leads connected to the patient. This may disconnect tubes or leads, restrict gas or liquid flow, or move sensors out of position. CAUTION:

w Do not continue to run the motor at the upper and lower limit positions; equipment damage may result.

3/Operation On/Off Power Switch and Circuit Breaker: (See Figure 3-1.) The On/Off power switch is located on the left side of the controller assembly (as viewed from the front) near the power cord socket. It is used for switching the power to the warmer(On and Off). The switch is also a circuit breaker and limits the maximum current drawn by the unit. If this circuit breaker trips when the warmer is operating, the power switch is deactivated to the Off position. To reset the circuit breaker, return the power switch to the On position. If the circuit breaker trips again, service is required. On/Off Switch

D. Alarms All alarms except system failure and power failure are preceded by a 30 second intermittent operator prompt tone. • • • • •

Probe Failure Alarm Patient Temperature Alarm System Failure Alarm Heat Off Alarm Check Patient Alarm

• Power Failure Alarm Probe Failure Alarm: The probe failure alarm is only active in the servo mode of operation. The alarm activates when the skin temperature probe fails electrically due to an open or short circuit, or is disconnected from the Warmer. The heater deactivates and the patient temperature display flashes “HH.H” or “LL.L” when this alarm condition exists. Patient Temperature Alarm: The patient temperature alarm is only active in the servo mode of operation. The alarm activates when the difference between the patient temperature and the control temperature is greater than 1°C. When the patient temperature returns to within 0.8°C of the control temperature, this alarm is automatically reset. Note: If the patient temperature probe reads below 30°C or above 42°C in servo mode, the heater is deactivated and “LL.L” or “HH.H” respectively, appears in the patient temperature display. Note: Qualified service personnel can adjust the alarm to trigger at a difference of 0.5°C and reset at a difference of 0.3°C. 3-4 6600−0371−000−DWG
