S E C T I O N 2 • D e s c r i p t i o n SECTION 2 Description The EQUATOR ® Convective Warming system consists of a high-flow convective warmer with hose-end temperature control, a convective warming blanket, and accessories. The convective warmer draws ambient-temperature air through a particulate air filter. The filtered air is warmed to a selected temperature. The warmed air enters the convective warming blanket through the hose and is distributed through delivery channels. Perforations on the patient side of the air delivery channels in the blanket gently disperse warm air over the patient. The convective warmer has three outlet temperature settings, which provide flexibility in patient treatment: 36°C, 40°C, and 44°C. These three temperature settings are servo-controlled by thermistors placed at the end of the hose where the hose connects to the convective warming blanket. A fourth temperature setting delivers ambient-temperature air. The temperature indicated on the control panel is the temperature of the air being delivered to the blanket at the end of the hose. A control thermistor adjusts the power applied to the heater to maintain the selected temperature. This enables the system to maintain the selected temperature under variations in ambient temperature. A safety thermistor provides a signal to a separate high-temperature comparison circuit. The safety thermistor activates and causes an alarm if the temperature exceeds the set point. The safety circuit provides an independent means of shutoff, which discontinues power to the heater and motor. This prevents patient exposure to excessive temperatures.

The layers are bonded together to form a distribution network of air delivery channels. The warm air is distributed around the blanket through the delivery channels and exits the blanket through a specially designed series of perforations in the patient side of the blanket. The distribution of air is designed to minimize temperature differences throughout the blanket. Refer to Appendix A, Convective Warming Blanket Identification Chart, for the list of blankets available. EQUATOR ® Convective Warmer | Operator’s <strong>Manual</strong> 3 1 2 3 4 5 6 7 8 9
