Wearable device is disclosed to quickly deliver thermal treatment. port. A separate material or component is later added through a port at point of injury or a medical event. Wearable thermal device comprises: at least one containment pack of selected shape; containment pack(s) contains a selected amount of first material (preloaded component); at least one port is attached to containment pack(s) configured to accept a second material (second component); and said second material is added through said at least one port to create a chemical reaction when combined with said first material. In one embodiment, first material needed to create an endothermic reaction is a selected amount of ammonium nitrate contained within wearable hypothermic treating device. A port or valve is configured to accept water. When a selected amount ammonium nitrate is combined with water a selected amount of thermal mass is created.

The invention provides a cooling pad 110 for alleviation of pain or discomfort, especially in the perineum as a result of childbirth. The pad 110 has at least one chamber 116 containing a fluid (such as saline) for cooling. There is at least one aperture 126 for allowing passage of body fluid. The aperture 126 is located inboard of the chamber 116.

Aperture 126 is formed in a web 124.

Cooling pad 110 may be used alone or as part of an assembly, sandwiched between cover layer 130 and peel-off backing 132, and is intended to be placed in a freezer prior to use.

An economical dual modality system is useful in a system for independent delivery of two distinct energy modalities to a mammalian body and includes a thermal subsystem. The thermal subsystem includes a thermal source affixed to flexible web having an adhesive surface and at least one structure arranged and configured to couple the thermal subsystem to a chassis comprising a durable energy subsystem.

There is described an apparatus for heating or cooling a material to be heated or to be cooled. The apparatus includes: a first compartment for containing the material to be heated or to be cooled; and a second compartment containing a phase change material, wherein the phase change material is either for generating heat to heat the first compartment or absorbing heat to cool the first compartment when undergoing a phase change. There are further described various different activating arrangements for activating a change of phase of the phase change material.

Cryosplint. In some embodiments, a cryosplint may include a vacuum splint and a cold pack. The vacuum splint may be configured to be wrapped around a body part of a patient and then have air evacuated therefrom in order to stabilize the body part. The cold pack may be configured to be attached to the vacuum splint in order to provide application of cold to the body part simultaneous to the vacuum splint stabilizing the body part.

Methods and devices are provided for activating brown adipose tissue (BAT) with cooling. Generally, the methods and devices can activate BAT to increase thermogenesis, e.g., increase heat production in the patient, which over time can lead to weight loss and/or improved metabolic function. In one embodiment, a medical device is provided that activates BAT by cooling tissue having a high density of cold sensitive thermoreceptors and/or by cooling BAT depots directly, thereby increasing thermogenesis in the BAT and inducing weight loss and/or improved metabolic function through energy expenditure.

A series of side-by-side inter-contacting cooling gel channels acting together form a body cool-down device which cools the body for at least three days or up to several weeks without needing re-soaking. Two semipermeable membrane sheets of fabric are attached together with a series of side-by-side channels sewn into the fabric. Granular super absorbent polymer or super absorbent polymer gel capsules are loaded into the channels. Soaking the device in water for five to fifteen minutes transforms the super absorbent polymer into a greatly expanded volume of cooling gel causing the channels to expand in contact with each other acting together as a single passive open system thermodynamic device for cooling a body.

A cervical collar that facilitates therapeutic hypothermia is provided and includes an outer shell having a front portion and a back portion fixedly coupled to the front portion on one side and removably coupled to the front portion on an opposite side. A fastening device removably couples the back portion to the front portion on the opposite side. At least one cooling device is provided on an interior of the outer shell to induce hypothermia in a patient. A sensor is provided that measures a physical characteristic of the patient.

Disclosed is a local cooling anesthesia device for spraying a coolant on a treatment site. The local cooling anesthesia device includes a housing which forms an outward form and from which the coolant is sprayed and a spraying unit installed in the housing to spray the coolant. The device also includes a cooling temperature regulator connected to the spraying unit to apply thermal energy to the sprayed coolant for temperature regulation and a control unit connected to the cooling temperature regulator to control the cooling temperature regulator. The cooling anesthesia device has functions of measuring and regulating the temperature of the coolant, and thus can apply the coolant to the treatment site within a safe temperature range according to the purpose of treatment, thereby enabling a desired treatment purpose such as local anesthesia to be safely and rapidly accomplished without side effects such as cytoclasis.
