  • Publication number: 20230381388
    Abstract: An extremely lightweight and compact heating system greatly increasing patient mobility is provided. The use of a flat plate can be used to greatly decrease package size and weight while providing comparable heat transfer by exploiting the ability of the dialysis bags to conform to this surface and through the greater heating area possible with the flat plate design. A short rim around the plate provides centering and protecting against minor leakage without substantially increasing package height. Protection against leakage is buttressed by sealing the rim to the plate and the use of 12 V only within the heating unit. The result is a lightweight warming device with a short that can be easily transported by the patient greatly improving patient lifestyle and freedom.

  • Patent number: 10864333
    Abstract: An auxiliary sensor can be used to measure the temperature of individual products in a heating cabinet. By arranging the temperature sensor with respect to the low mass thermal conductors and insulators, the sensor can be focused on the product to obtain the proper temperature irrespective of the immediate environment whether it is at room temperature or even within the heating cabinet.

  • Publication number: 20140199057
    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.

  • Patent number: 8775201
    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.

  • Patent number: 8581152
    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.

  • Publication number: 20130091782
    Abstract: A system and a method for insulating a building having a flexible fabric roof and for preventing displacement of an insulating blanket of battings inside the building that displacement would otherwise occur in response to wind creating a billowing action of the flexible fabric roof. Anti-billowing anti-displacement means prevent movement and displacement of an insulating blanket of battings inside the building that would otherwise occur in response to wind and other external forces moving the outer flexible fabric roof.

  • Patent number: 8362402
    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.

  • Patent number: 8217316
    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.

  • Patent number: 8158910
    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.

  • Patent number: 8076618
    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.
