Abstract:
1. A convective warmer for outputting heated air at different flow rates to different patient warming blankets each adapted to be optimally inflated by the heated air at one of the flow rates, comprising: a blower for directing the heated air to an outlet of said warmer, said outlet adapted to connect to an inlet of each of the blankets to establish a fluid path to the blanket connected to said outlet; a controller for controlling the flow rate of the heated air to be provided by said blower to the blanket connected to said outlet; a valve within said warmer having a variable opening operable to control the flow rate of the heated air fed to said outlet; at least one switch actuatable by a user to effect said controller to control the amount of restriction said valve places on the flow of the heated air to said outlet so that the optimal flow rate of the heated air for the blanket connected to said outlet is output from said warmer to the blanket so that the heated air output from said warmer fills the blanket connected to the outlet at an optimal rate and at a sufficient pressure to ensure that the heated air continues to be output from the blanket to warm the patient covered by the blanket.
