A body cooling system including a housing having a top portion, side portions, and a bottom portion. The top portion and the bottom portion include at least one opening. Additionally, the body cooling system includes at least one mesh layer and an absorbent layer at least partially surrounded by the mesh layer.

The present invention provides improved devices for removing energy and fluid from body fluid containing spaces and surfaces of a mammal, and new uses for such devices, including fluid removal, energy removal, increasing metabolic rate; promoting weight loss; preventing esophageal burn-through, reducing beta-amylase accumulation in the brain, delaying or inhibiting the onset of Alzheimer's and other senile dementia.

A treatment system delivers a breathing gas and frozen ice or other particles (FSP) to a bronchus of a lung of a patient in order to induce hypothermia. The breathing gas and the FSP are usually delivered through separate lumens. Clogging of an FSP lumen can be inhibited by heating and/or cooling of the lumen. The temperature of exhaled gases or a body temperature may be measured, and a controller can adjust the duration or rate at which the ice particles are delivered in order to control the patient's core temperature based on the measured temperature.

This application relates to a hand-held cooling device for supplying a cryogen to a target region for cryotherapy. The device can include a cryogen container configured to contain a first cryogen having a first temperature and a nozzle configured to spray a first modified cryogen to the target region, the first modified cryogen having a second temperature higher than the first temperature. The device can also include a cryogen temperature regulator configured to receive the first cryogen and output the first modified cryogen to the nozzle, the cryogen temperature regulator disposed closer to the nozzle than the cryogen container. The cryogen temperature regulator can include a holder tube, a porous structure disposed inside a holder tube and a heater disposed around the holder tube and heating the holder tube so as to increase the first temperature to the second temperature while the first cryogen passes through the porous structure.

This application relates to a hand-held cooling device for supplying a cryogen to a target region for cryotherapy. The device can include a cryogen transfer unit configured to receive a first cryogen from an external cryogen reservoir, the first cryogen including i) a first amount of a liquid phase cryogen and ii) at least one of a first solid phase cryogen and a first gas phase cryogen. The device can also include a nozzle configured to spray a first modified cryogen to the target region. The device can further include a cryogen liquefier disposed between the cryogen container and the nozzle and configured to cool the first cryogen received from the cryogen transfer unit and output the first modified cryogen to the nozzle, the first modified cryogen including at least a second amount of the liquid phase cryogen more than the first amount of the liquid phase cryogen.

A self-contained portable air distribution system for cooling an individual by the movement of intake and exhaust air flow streams over an individual. The system includes a portable rechargeable battery operated fan that produces both an inlet intake and outlet exhaust air flow streams that provides a cooling effect by evaporating body moisture as it passes over the body.

Apparatus for cooling an object, space, or tissues of a patient. A vacuum chamber is designed to be placed in thermal contact with the object or space to be cooled, or against a patient to be treated. A water sprayer is configured to spray water into the vacuum chamber or against a cooling wall of the chamber. A vacuum pump and control are designed to maintain vacuum below ambient pressure in the vacuum chamber sufficient to cause accelerated evaporation of the water and cooling to a temperature desired for cooling of the object, space, or patient.
