Open care  Warmer is designed to provide quick and effective treatment for newborn infants suffering from extreme heat loss. Thus, this equipment is suitable for NICU, labor rooms, and nurseries.

The open care warmer consists of a cart and a bassinet assembly. Also a heater module within examination light and a pillar module which consists of a controller and SMPS. The basic unit is also equipped with one removable instrument tray mounted on the pillar module at the rear of the bassinet.



  1. Heater power – 650 Watt
  2. Examination light – 9 watt
  3. Power cable length – 3 meter
  4. Fuse used – 4 Amperes
  5. Lastly, power source – 220 volt Ac/50 Hz 


Paint & Coating – MS Fabrication with power coating.

Castor – Each unit has four castor, two lockable.


Skin:32 degrees to 38 degrees

Resolution:0.1 degree

Heater Module

The radiant energy directed by the parabolic reflectors on the infant. The radiant energy can also be controlled either manually or by mean of skin temp sensor which controls the radiant energy to maintain a selected skin temperature.


When operated in manual control mode, the controller permits the operator to adjust the heat output of the heater module from zero to maximum settings. Thus, during the manual mode a patient probe can be used to monitor the skin temperature. Moreover, when operated in skin temperature control mode, the controller utilizes a skin temperature probe connected in between the controller input and the infant to automatically adjust the heat output of the heater module to maintain a selected preset skin temperature. Up and down switches permit adjustment of skin temp set point and a digital display provides temperature read out.

Examination light

  • Dazzle-free observation light for examination of the infant.
  • Also, the dual side swivel heater provided access for x-ray and other procedure.

Apgar timer

  • This mode used to take the infant Apgar score within specified time.
  • Also, in this mode one can start and stop, just press Apgar switch.


Each time the unit is turned on, an automatic test sequence is initiated to verify that the visual display and the audible alarms are functional. Alarms are provided for high and low skin temperature. 

Set point (high)

If the temp sensed by the skin probe is 0.5 degree above the set temperature, a high set point alarm will occur after a delay of 10 second. In addition, the audible portion of the alarm can be silenced by depressing the alarm mute switch. However the visual indicator will continue. If the condition is not corrected within 20 sec the audible alarm will resume. When the alarm condition is corrected, the circuit will reset.

Set point (low)

If the set temperature sensed by the skin probe is 0.5 degree less than the set point, a low set point alarm will occur after a delay of 10 seconds.

Probe fail

During skin control mode, if the skin temp probe open short or un-plugged, the probe failure alarm will indicate the baby temperature display and the heater will be turned off.This alarm cannot be rest until the alarm condition is corrected.

Warmer-Modes of Operation:-

Servo mode

In this mode infant temperature sensed with the help of a skin temperature probe. Also, the heater power automatically controlled so that infant temperature lies in the desired range. This is set by the user.

Manual mode

For this mode, we can manually set the power of the heater  ranging from 10 percent to 100 percent

Air mode

Under this mode we used the special thermistor probe which has the ability to measure the air temperature near the infant. Thus, in mode control unit continuously measures the air temperature with the help of air probe and sets the heater power. This helps to achieve the set temperature as required by the user.
