Abstract: A heating cabinet for IV bags provides a uniform thermal field promoted by circulated heated air passing through air permeable shelves. Temperatures of the IV bags are modeled through a knowledge of a temperature of the uniform thermal field and arrival time of the IV bags eliminating a need for separate temperature sensors and control loops. Bag status may be signaled through modulated light distinguishable by individuals with limited color sensitivity. Signals are associated with particular IV bags by projecting the light of the signals into the IV bags themselves.

Abstract: A warming system for large volume dialysis bags provides a basin configured to position the bags in a low thickness, wrinkle free configuration for maximum heat transfer. A centrally positioned thermal sensing element may provide accurate temperature measurement of interior bag temperature by a correction process and a weight sensor may automatically control the heater when the bag is in place.

Abstract: A data logging module and a method of monitoring a medical warming cabinet is disclosed. A temperature of the heating chamber and a state of a door of the heating chamber are sampled at predetermined intervals and recorded as data packets on a memory device. A display may provide a message when the memory device is reaching capacity. Moreover, a selected of the data packets may be analyzed (such as the data packets excluding the data packets when the door is open) for the generation of a report. The data packets from the memory device may be transferred from the memory device to an external memory device as necessary.

Abstract: A heating system is disclosed including a cabinet, at least one heating pad subassembly, and a plurality of couplings. The cabinet has walls defining an interior heating chamber. The heating pad subassembly is disposed on an exterior surface of the walls of the cabinet and includes a heating element and a plurality of openings formed there through. The plurality of couplings includes a plurality of coupling first portions disposed on the exterior surface of the walls and a plurality of coupling second portions coupled to the plurality of coupling first portions. At least a portion of the plurality of couplings extend through the plurality of openings in the heating pad subassembly, thereby coupling the heating pad subassembly to the cabinet.

Abstract: A fluid warmer is disclosed. The fluid warmer includes a support surface, a heating element configured to selectively heat the support surface, and a switch assembly extending through the support surface. The switch assembly includes a switch, a movable switch plate, and a thermocouple. The switch has at least two states, one of which indicates the presence of an item on the support surface. The movable switch plate operably links to the switch to move the switch between the states and further includes a contact surface that contacts an item placed on the support surface. One or more thermocouples are embedded in the movable switch plate below the contact surface. The movable switch plate comprises a material having a thermal conductivity that permits the thermocouple(s) embedded in the switch plate to measure a temperature of an item placed on the support surface within a predetermined period of time.

Abstract: A heating system is disclosed including a cabinet having walls defining an interior heating chamber. Sensors are attached to an exterior surface of the walls. Heating pad subassemblies are attached to the exterior surface of the walls with each heating pad subassemblies located adjacent a corresponding sensor. The heating pad subassemblies include a pad having an attachment face coupled to the exterior surface of the walls and a heating element coupled to the pad. A controller is in electrical communication with the heating elements and the sensors. This controller is configured to independently monitor temperate measurements from each of the sensors and to independently control each of the heating elements. The heating pad subassemblies are positionable on the exterior side of the plurality of walls and the heating system compensates for load variations across the interior heating chamber.

Abstract: A medical warming cabinet and a method of installing a controller into a medical warming cabinet is disclosed that allows for easy transfer of operation parameters between controllers. Should a controller fail, the removable memory device can be removed from the failed controller and inserted into the replacement controller. This provides the benefits of a generic controller (e.g., low cost and good availability), but eliminates the tedious and costly necessity of having to reprogram the controller during maintenance.

Abstract: The present invention provides a modular fluid warmer and a method of stacking a plurality of modular fluid warmers. As each of the modular fluid warmers is independently operated, the modular fluid warmers are energy efficient. Further, each modular fluid warmer may be equipped with sensors and a controller that reduces the required amount of user interaction with the modular fluid warmer.
