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.

The invention can selectively heat a diseased area in the lung while minimizing heating to the healthy area and surrounding tissue. This is done by exposing the lung to an electromagnetic field causing dielectric or eddy current heating. The invention is particularly useful for treating emphysema as the diseased areas have reduced blood flow. The diseased area will heat up rapidly while the healthy tissue will be cooled by the blood flow. This is particularly effective for treating emphysema because of the low mass of the lungs and the high blood flow. To avoid heating of surrounding organs the direction of the electromagnetic energy is switched in a way it always passes through lungs but only intermittently passes through adjacent organs. If heat activated drugs are present in the lungs, they are selectively released in the heated tissue.

A gel-pack has a plurality of self-contained components organized as layers in an interior chamber of the gel-pack. Each layer may be inserted into, and removed from, the interior chamber individually. The components include a solid-state gel layer that stores thermal energy, a first radiant energy barrier that prevents the transfer of thermal energy radiating from an exterior of the gel-pack into the solid-state gel layer, and a second radiant energy barrier that reflects the thermal energy radiating from the user's body into the solid-state gel layer.

The present disclosure relates to a mask, a device and a method for whitening skin. In an embodiment, the mask includes a contact layer having a lower portion configured to contact a face surface of a user, and at least one thermoelectric module including a first major surface disposed in contact with an upper portion of the contact layer and a second major surface positioned opposite to the first major surface. The mask also includes a heat dissipation layer being disposed in contact with the second major surface of the thermoelectric module. The mask further includes a controller configured to control the thermoelectric module to: cool the first major surface at a cooling temperature such that the skin of the user reaches a target temperature at which a pigmentation by melanocytes on the user's skin is suppressed, and maintain the cooling of the first major surface for a cooling interval.

At least some aspects of the present disclosure direct to a device including a conductive heater and a convective device. The conductive heater includes a first conductive bus and a second conductive bus, a first set of electrodes electrically connected to the first conductive bus, a second set of electrodes electrically connected to the second conductive bus, wherein the first and the second set of electrodes are interdigitated, and a plurality of heater stripes comprising printed ink and electrically connected to the first and the second sets of electrodes. The convective device includes a pneumatic structure and an opening into the pneumatic structure connected to an inflation medium source, wherein at least part of the convective device is air permeable. The application is further directed to a warming device comprising a gown and said device, wherein the conductive heater and convective device are disposed on or integrated with the gown.

A programmable cold therapy system is employed for pain relief and healing following injury or surgery. The system has a tank that maintains a reservoir of ice water. A pump is received within the tank and draws cold water from the reservoir to a cooling pad positioned over a region of the patient's or user's body requiring cold therapy. A control panel selectively interconnects a power source with the pump to control a period of time that the pump may be operative, and further controls periods of time during which the pump is actually operative. Within a first period of time, the pump is enabled, while it is actually actuated during repetitive second periods of time to operate at a selected duty cycle.

One variation of a method for fabricating a dermal heatsink includes: fabricating a substrate defining an interior surface, an exterior surface opposite the interior surface, and an open network of pores extending between the interior surface and the exterior surface; activating surfaces of the substrate and walls of the open network of pores; applying a coating over the substrate to form a heatsink, the coating comprising a porous, hydrophilic material and defining a void network; removing an excess of the coating from the substrate to clear blockages within the open network of pores by the coating; hydrating the heatsink during a curing period; heating the heatsink during the curing period to increase porosity of the coating applied over surfaces of the substrate; and rinsing the heatsink with an acid to decarbonate the coating along walls of the open network of pores in the substrate.

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.

A therapeutic device such as an eye mask or compress for delivery of moist heat therapy to a body part such as an eye of a human or animal subject. Example devices are configured to be worn with one or more eye coverage portions positioned over the subject's eye(s). The eye coverage portions have a front side configured for placement against the treated body part, and a back side opposite the front side. The eye coverage portions include recesses or retracted sections configured to be positioned over the wearer's cornea area. The shell of the eye coverage portions may further incorporate antimicrobial properties. Heat transfer mediums or fill materials can include hydrophilic zeolite, silica gel, and/or one or more phase change materials so as to provide controlled performance characteristics.
