Disclosed herein is a medical pad for exchanging thermal energy between a targeted temperature management (TTM) fluid and a patient. The pad can include a central pad and a plurality of extension pads coupled with the central pad, where the extension pads extend away from right and left lateral sides of the central pad and where each of the central pad and the plurality of extension pads includes a fluid containing layer configured for circulation of a TTM fluid therein. A method can include removing a portion of the hydrogel liner and placing a remaining portion of the hydrogel liner between the hydrogel layer and the patient. The method can also include rotating and folding one or more of the extension pads to defeat the thermal energy exchange of the rotated and folded extension pads.

A thermal pad is adapted to be placed in physical contact with a patient and to receive temperature controlled fluid from a thermal control unit. The temperature controlled fluid circulates through the thermal pad and controls the patient's temperature. The thermal pad includes first and second sheets that are sealed together about their periphery to define a fluid chamber there between. A fluid inlet and fluid outlet are fluidly coupled to the fluid chamber. In some embodiments, a filter sheet is sandwiched between the first and second sheets and arranged such that fluid entering the fluid inlet must pass through the filter sheet before exiting out of the fluid outlet. A plurality of bonds may be included that seal the first and second sheets together at a plurality of locations. In some embodiments, a non-sheet filter is positioned within the fluid chamber and filters the circulating fluid.

Disclosed is a medical pad for exchanging thermal energy between a targeted temperature management (TTM) fluid and a patient. The pad includes a fluid channel extending between a fluid inlet and a fluid outlet, and a bottom channel wall that is disposed between the fluid and the patient during use of the pad. The wall is formed of a material having a thermal conductivity, and the wall includes elements embedded within the wall. The elements are formed of a material having a greater thermal conductivity than the wall material so that a composite thermal conductivity of the wall that is greater than the thermal conductivity of the wall material alone. The thermal energy exchange between the fluid and the patient is defined in accordance with the composite thermal conductivity. The pad can include channel shapes and features that enhance the heat transfer convection coefficient of the fluid within the channel.

This cooling apparatus includes a tube (10) having an opening portion (10a) in one end portion in a longitudinal direction thereof, a cap (30) capable of opening/closing the opening portion (10a), a non-freezing drinkable coolant (20) that fills the tube (10), and a container (50) that contains the tube (10) filled with the coolant (20). The tube has a constricted portion (10d) having a reduced inner diameter.

The invention presents methods and devices for controlling and modifying the core body temperature of a human or other mammal. The apparatus contains an element to be placed in contact with an individual's skin, such as the palm of a hand or sole of a foot; the element emits radiation, preferably within the red to infrared range of 550 nm to 950 nm, inducing vasodilation and increased blood flow in the region beneath the contacting area. A heat exchange element is concurrently in contact with the skin, capable of transferring heat into or removing heat from the circulatory vasculature, through the skin surface. The circulatory system carries the increase or decrease in thermal energy to the body's core organs. As such the method and devices are capable of increasing or decreasing the core body temperature, or maintaining current core body temperature in the presence of external thermal elements.

A cooling system having a multitude of fluidly coupled cells for receiving a coolant is disclosed. The cooling system is characterized in that the cooling system has a flexible cover that covers the multitude of cells, an air gap between the flexible cover and the cells and an air pump for modifying the air gap.

At least some aspects of the present disclosure feature a configurable convective device, including two layers forming a pneumatic structure and an air-guide device. The pneumatic structure includes two portions and an inflatable channel connecting the two portions. In some cases, the air-guide device is disposed within or proximate to the inflatable channel and configured to direct flow of inflation medium when at least one of the two portions are bent.

A device and method for a wearable heat pack is presented. The heat pack provides a therapeutic application of heat or cold to a user using phase-change material to provide a desired temperature and is made of a soft and flexible material that is comfortable and pleasant to use, but is strong enough to be reused multiple times. The heat pack device includes a sealed silicone envelope. An infill is contained in the envelope and includes a phase-change material for providing a temperature range over a period of time. The method includes heating the heat pack device, placing the heat pack device in a pocket of a garment, and placing the garment on a user to position the heat pack device in contact with the user, wherein the heat pack device includes a phase change material and further wherein the heating creates a phase-change of the phase-change material.

Disclosed is a system which employs a cooling or heating pad which is preferably rechargeable with hot or cold temperatures at an intended area of the body. The pad includes a highly temperature-conductive or temperature-retentive material which can be cooled or heated using a portable source of heat or cold material delivered to the pad by a removable delivery conduit. Valves can be included to regulate flow of the cooling or heating material from the source to the pad. The system can also include a dual-chambered canister for containing two different media for heating, cooling or for alternating heating and cooling the pad.

A therapeutic sleeve and techniques for using it are provided. A therapeutic sleeve may house a conduit carrying a constant stream of a chilled or heated working fluid throughout the sleeve. A heating element may evenly distribute heat throughout the sleeve. The sleeve may provide a precise temperature-controlled pocket that significantly improves treatment of pain or discomfort in the user's feet, head, or other body parts. A software application may enable a user to set or adjust a temperature, set timers, record sleep patterns, and view analytics or other data.
