Wearable heat transfer devices and associated systems and methods are disclosed herein. In some embodiments, a representative heat transfer device can comprise (i) thermoelectric components each having a first side and a second side, (ii) a heat transfer system having a heat exchanger and an array of fluid distribution networks, in which individual fluid distribution networks are thermally coupled to the second side of a corresponding one of the thermoelectric components and fluidically coupled to the heat exchanger, and (iii) a flexible support unit coupled to the first sides of the thermoelectric components and extending at least between individual thermoelectric components, wherein the flexible support unit is a heat spreader configured to enhance heat transfer from a target area.

A non-invasive, non-surgical, medication free therapy system for application to a targeted body location is provided. The therapy system includes a pouch having a first side and a second side. The first side is configured for contact with the targeted body location. Each of the first and second sides has an inner surface. The inner surfaces of the first and second sides define an internal cavity. A cold temperature source is contained within the internal cavity and is in direct contact with the inner surfaces of the first and second sides. One or more attachment straps are configured for attachment to the second side of the pouch and further configured to position the therapy system adjacent to the targeted body location. The one or more attachment straps still further configured for repeatable and removable attachment to the pouch.

The system includes a pump, a heat exchanger, a bladder, a thermometer, and a controller. The heat exchanger is in fluid communication with the pump. The bladder is configured to be placed over a carotid artery, and is in fluid communication with the heat exchanger. The thermometer is located with respect to the heat exchanger and configured to measure a temperature of fluid downstream from the heat exchanger. The controller is in electrical communication 28 with the thermometer and the heat exchanger. The controller is configured to 20 control power delivered to or flow through the heat exchanger such that the temperature of the fluid downstream from the heat exchanger measured by the thermometer is between 2 degrees C. and 10 degrees C. for between 10 minutes and 50 minutes.

Provided is an endothermic towel which can react with moisture of a human body to cause an endothermic reaction, thereby removing thermal sensation and at the same time, rapidly drying moisture to give cool sensation to a user. The endothermic towel includes a towel body having an endothermic function; and a plurality of through-holes provided to the towel body in order to accelerate the endothermic function, so that the endothermic function may be optimized.

A therapeutic collar comprising an elongate body made from a flexible material for extending around at least a portion of the neck of a patient. The body has a length approximating the circumference of the neck, two thermoelectric devices for overlying two carotid arteries in the neck and two thermoelectric devices for overlying of two vertebral arteries in the neck when the elongate body is secured around the neck of the patient. At least one cooling tube is carried by the elongate body and extends in the vicinity of each of the thermoelectric devices for removing heat from the thermoelectric devices.

Methods and devices are disclosed for infrared phototherapy. The device can include a flexible substrate, a plurality of infrared light sources associated with the substrate and a drive circuitry configured to couple to a power supply and connected to the light sources to activate the light sources to emit infrared radiation. The device can be positioned on a subject's body to transmit infrared radiation to a target region of skin or muscle tissue of a subject to raise the temperature of the target region above normal body temperature. The plurality of light sources can be disposed in a spaced-apart relationship on the substrate such that collectively they emit infrared radiation in an overlapping pattern that provides for substantially uniform exposure of a target region. The substrate can be actively cooled to control the surface temperature of the target region. The device can further include a light-transmissive sealing element to isolate the LEDs from contact with the subject's body.

The system includes a pump, a heat exchanger, a bladder, a thermometer, and a controller. The heat exchanger is in fluid communication with the pump. The bladder is configured to be placed over a carotid artery, and is in fluid communication with the heat exchanger. The thermometer is located with respect to the heat exchanger and configured to measure a temperature of fluid downstream from the heat exchanger. The controller is in electrical communication 28 with the thermometer and the heat exchanger. The controller is configured to 20 control power delivered to or flow through the heat exchanger such that the temperature of the fluid downstream from the heat exchanger measured by the thermometer is between 2 degrees C. and 10 degrees C. for between 10 minutes and 50 minutes.

A thermal therapy garment system includes a garment assembly having a compression garment including an outer surface, an inner surface having a pocket, and a thermal pack. The pocket is located on the inner surface of the compression garment and is strategically placed on the compression garment such that thermal therapy is enabled on a target area of a body of a user-wearer. The target area of the body of the user-wearer is a muscle, a joint, or both. A compression garment may be worn underneath everyday clothing and may be concealed under everyday clothing.

Methods of operating a haptic actuator to apply physical and/or thermal sensations to a user to provide subjective symptom relief to a user are described. In some embodiments, a haptic actuator may be automatically activated when one or more detected user states are compared to one or more predetermined activation parameters to determine the user is experiencing an episode related to a condition of the user. In another embodiment, one or more operating parameters of a haptic actuator may be updated if the haptic actuator did not provided a desired amount of subjective symptom relief to a user during use. In yet another embodiment, a haptic actuator may create an event log based on activation events when the haptic actuator is used to provide symptom relief for a condition of the user.
