A hot air producing system produces and stores hot air, and applies the stored hot air to a human body. The system includes a heating apparatus to heat the air, a temperature setting gauge to allow a user to set a desired temperature, a pressure gauge to measure a pressure of the air in the container, a pump to pump the hot air, a fill connection, an expandable container for receiving and storing the hot air, with a valve to connect to the fill connection such that the expandable container can receive the hot air, an adjustable flow release mechanism to allow a user to adjust an amount of flow of hot air out of the expandable container, and a flexible hose connected to the adjustable flow release mechanism, with a nozzle to direct the hot air to a portion of the human body.

A wearable cooling apparatus (2) comprising a pad (4), an inlet valve (6), a channel (8), and a thermally conductive membrane (10). The channel (8) is an open-sided recess formed in the surface of the pad (4) and the pad (4) is secured to the membrane (10) such that the open side of the channel (8) is covered by the membrane (10). The covered channel (8) forms a conduit (11) arranged between the pad (4) and the membrane (10), wherein the walls of the conduit (11) comprise the surface of the pad (4) and the surface of the membrane (10) and the inlet valve (6) is arranged in fluid communication with the conduit (11).

The present invention provides methods and devices for controlling a cold slurry that is delivered to a target tissue and for limiting heat transferring from surrounding tissue to the target tissue. In particular, a balloon structure is deployed at or near a point of delivery to act as a physical and/or thermal barrier. In some instances, the balloon structure can act as a pressure device obstructing the flow of warm blood into a treatment area, which can melt the cold slurry.

Disclosed is a system and method for producing and storing hot air, and for applying the stored hot air to a human body. The hot air producing system may include a heating apparatus configured to heat air to a temperature, a temperature setting gauge, a pressure gauge, a pump to pump the hot air, a fill connection, a container for receiving hot air from the heating apparatus and storing the hot air therein, the container including at least one valve to connect to the fill connection of the heating apparatus such that the container can receive the hot air from the heating apparatus, an adjustable flow release mechanism connected to an outlet of the container for receiving the hot air, and a flexible hose connected to the adjustable flow release mechanism. Embodiments of the invention can include a computer system capable of governing all the components.
