Description<br />
The EQUATOR ® <strong>Convective</strong> Warming system consists of a high-flow convective warmer with hose-end<br />
temperature control, a convective warming blanket, and accessories.<br />
The convective warmer draws ambient-temperature air through a particulate air filter. The filtered air is<br />
warmed to a selected temperature. The warmed air enters the convective warming blanket through the hose<br />
and is distributed through delivery channels. Perforations on the patient side of the air delivery channels in<br />
the blanket gently disperse warm air over the patient.<br />
The convective warmer has three outlet temperature settings, which provide flexibility in patient treatment:<br />
36°C, 40°C, and 44°C. These three temperature settings are servo-controlled by thermistors placed at the end<br />
of the hose where the hose connects to the convective warming blanket. A fourth temperature setting delivers<br />
ambient-temperature air. The temperature indicated on the control panel is the temperature of the air being<br />
delivered to the blanket at the end of the hose. A control thermistor adjusts the power applied to the heater to<br />
maintain the selected temperature. This enables the system to maintain the selected temperature under<br />
variations in ambient temperature.<br />
A safety thermistor provides a signal to a separate high-temperature comparison circuit. The safety thermistor<br />
activates and causes an alarm if the temperature exceeds the set point. The safety circuit provides an<br />
independent means of shutoff, which discontinues power to the heater and motor. This prevents patient<br />
exposure to excessive temperatures.<br />
