A convective warmer to which blankets of different dimensions may be connected is capable of providing air to the various blankets at flow rates that optimally inflate those blankets to achieve the optimal clinical result for the patients covered by those blankets. The blanket connected to the warmer may range from a full size adult warming blanket to a pediatric or neonate warming blanket. There is provided on each blanket a code, marking or marker, to be read by a sensor(s) provided at the outlet of the warmer, that identifies the type of blanket when the blanket is coupled to the warmer. Consequently, heated air may be automatically output by the warmer to the blanket at the appropriate flow rate of that blanket to optimally inflate the blanket without any need for intervention by a user. In addition to being used to control the flow rate of the heated air, the code from the blanket may also be used to control the temperature of the heated air to be input to the blanket.

The warm air blower system can include a compression unit and a plenum chamber having a plenum member with a curvilinear interior surface, the plenum member interior surface has a plurality of surface indentations to enable the formation of controlled local turbulence adjacent the interior surface to reduce friction and noise as the compressed air moves across the interior surface. The warm air blower system can be appropriately mounted on a vertical pole, bed, stand or floor mounted. Air filters can be used to filter the air before and after induction to the compression unit. The safe operation of the warm air blower system is appropriately controlled and monitored by a control unit that includes a thermostat.

A convective warming blanket is configured to have an upper body portion and two leg portions that extend from a distal end of the upper body portion. The leg portions are separated by a space sufficient to expose a lateral side of a patient covered by the blanket. A flap separable from the leg portion that extends from the mid-section of the upper body portion may be used to securely wrap around the extended arms of the patient, who is lying on his side. Adhesive tapes are provided on the outside edges of the leg portions to secure the blanket to the surface onto which the patient lies. Apertures are appropriately formed at the sheet that comes into contact with the patient at the upper body portion and along the respective inner side edges of the leg portions so that both the upper body and the exposed lower body of the patient are warmed by heated air. The blanket is designed to have mirror image versions usable for exposing the lateral left side or the lateral right side of the patient.

A convective warmer to which blankets of different dimensions may be connected is capable of providing air to the various blankets at flow rates that optimally inflate those blankets to achieve the optimal clinical result for the patients covered by those blankets. The blanket connected to the warmer may range from a full size adult warming blanket to a pediatric warming blanket. The convection warmer may have multiple fixed air flow rates each selectable by a user, via switch(es) either electronically or mechanically. For the electronic selection of a given flow rate, a motor adaptable to rotate a different speeds is used. To vary the flow rate mechanically, a valve is controlled to vary the amount of air that may pass to the blanket. Instead of different fixed flow rates, variable air flow rates, selectable by the user, may be used. Also, a feedback circuit that maintains the pressure sensed at the outlet of the warmer to a preset pressure may be used to eliminate the need for user intervention.
