Abstract
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.
