Abstract:
1. A liquid warming device for maintaining fluids used in the provision of medical treatment at a temperature above ambient air temperature, the liquid warming device comprising: a first heating element adapted to directly apply heat to a volume of liquid to maintain the volume of liquid at approximately a target temperature, the liquid warming device adapted to be used with a volume of liquid that is not fully enclosed so that the volume of liquid can be readily accessed by someone providing medical treatment; at least one access sleeve located within the liquid warming device, the at least one access sleeve open to ambient air at an open end and closed at an opposite end, the opposite end connected to the open end by a set of one or more walls running from the open end to the opposite end; a second heating element in thermal contact with at least a portion of the set of one or more walls of the at least one access sleeve, the second heating element responsive to a control system; and a first temperature sensing device in data communication with the control system used to regulate the operation of the second heating element in order to selectively apply heat to a closed container of sterile fluid placed in the at least one access sleeve.
