A thermal device includes an inflatable non-perforated blanket, a conduit structure, and a recirculating assembly. The inflatable non-perforated blanket is configured to transport warm air internally. The conduit structure is configured to provide conduit to transport the warm air externally to the inflatable non-perforated blanket. The recirculating assembly is configured to inflate the inflatable non-perforated blanket with the warm air and: (1) to cause the warm air to flow from the first port to the second port in a first direction, and (2) to recirculate the warm air through the conduit structure to flow from the second port to the first port in the first direction. The inflatable non-perforated blanket includes first and second sheets. The first sheet faces ambient air and has a first thermal conductivity. The second sheet faces the subject body and has a second thermal conductivity higher than the first thermal conductivity.

A thermal control unit controls the temperature of a fluid delivered to one or more thermal transfer devices (e.g. thermal pads) in contact with a patient. The thermal control unit generates thermal data while being used to treat the patient and is adapted to receive thermal history data previously generated by a different thermal control unit in the treatment of that patient. Both the current and previous thermal data are displayable on the thermal control unit currently being used, thereby giving the caregiver a complete picture of the thermal history of the patient. The thermal control unit may also be adapted to transmit its thermal data, as well as the thermal history data previously received from the other thermal control unit, to still another thermal control unit. The thermal history data transfer may take place via a cable, wirelessly, by a portable flash drive, or by other means.

Disclosed herein is a system, apparatus and method directed to patient temperature control. The system can include a control module configured to provide fluid that is heated or cooled, a heating and cooling system configured to couple with the control module and receive the fluid, and a temperature sensor coupled to the control module, the temperature sensor configured to measure a body temperature of a patient and provide signals to the control module that indicate the body temperature. The system can include a neurostimulation device coupled to the control module to provide neurostimulation to the patient. The control module can include logic, stored on non-transitory, computer-readable medium that, when executed by one or more processors, causes performance of operations including generation and transmission of first instructions to the neurostimulation device causing initiation of a first neurostimulation procedure.

A thermal pad for controlling a patient's temperature includes first and second chambers defined between interior and exterior layers. The first chamber circulates a temperature controlled fluid from a first inlet to a first outlet. The second chamber is in fluid communication with a port and a plurality of holes defined in the interior layer. Pressurized gas supplied to the second chamber is vented onto the patient to control the microclimate between the patient's skin and the thermal pad. An additional third chamber is provided in some embodiments that urges the thermal pad into contact with the patient when subjected to negative gauge pressure. In other embodiments, a negative gauge pressure chamber is allowed to partially inflate in order to urge the thermal pad into contact with the patient.

An article configured to warm and monitor a patient during a dialysis treatment, the article includes one or more heating elements. The article also includes one or more sensors configured to monitor a condition of the patient during the dialysis treatment. The article also includes a fabric portion configured to receive the one or more heating elements and the one or more sensors and position the one or more heating elements and the one or more sensors on the patient during treatment. The article also includes a transmitter configured to transmit information from the one or more sensors to a dialysis machine and an electrical connector configured to provide power to at least one of the one or more heating elements and the one or more sensors.

A bed sheet heating pad comprises a plurality of control area, each control area comprising a thermal controlling unit, a heating unit, a pressure/temperature sensing unit, a communication unit and a power source, the thermal controlling unit is for receiving control signals from the communication unit to control the heating unit to generate heat, the pressure/temperature sensing unit is for sensing the pressure/temperature of the heating unit and transmitting the sensing signal to the thermal controlling unit to control the temperature of the heating unit, the communication unit is connected to a central control unit and receiving control signal from the central control unit to control the temperature of the control area, and the power source is for supplying the power used in each unit.

An air blower has an inlet muffler and an outlet muffler to reduce the noise of the air blower during operation. Each of the mufflers may have two sections. One section is configured to attenuate high frequency noise and the other section is configured to attenuate lower frequency noise. A tubular internal wall in each of the mufflers defines the through passage for each of the mufflers. A noise absorbent material may be fitted about the tubular wall within each muffler. A plurality of holes are formed along the tubular wall of each through passage to expose the through passage to the noise absorbent material. A heater plenum may be interposed between the blower plenum and the outlet muffler to heat the air from the blower plenum. A filter at the input muffler filters the air sucked into the air blower.

A baby space warmer system includes a baby space warmer having a heating element and/or a power source disposed in a housing and a controller that is operable to control the heating element and/or power source. The controller may control the heating element to warm to a warming temperature, switch to maintaining a maintenance temperature, and then cease heating. The controller may control the heating element in this way using regulation of voltage and/or one or more components, such as one or more timers, thermostats, thermometers, and so on. In some implementations, a baby space warmer system may include a warming container configured to contain the baby space warmer, concentrate heat generated by the baby space warmer to speed heating of the baby space warmer to the warming temperature, retain heat generated by the baby space warmer to maintain the heating temperature and/or the maintenance temperature, and so on.
