Cooling bed system
A cooling bed system is configured to provide a cooling airflow around a patient suffering from heat exhaustion, heat stroke and or burns. A cooling bed system produces an airflow over a patient and preferably an airflow from both above and below the patient to more effectively and quickly cool the patient. A cooling bed system may also include a liquid dispenser that creates mist that is carried by the airflow to further cool the patient. A patient may be supported by a platform having a plurality of openings to allow airflow and mist to pass therethrough. A controller controls the airflow rate and/or temperature of the air, and may also control the liquid dispensing rate and/or temperature of the liquid as a function of an input from a temperature sensor to effectively and safely cool the patient.
