Disclosed are thermoregulatory systems. In particular, thermoregulatory devices are incorporated into garments for warming and cooling a user's body. Thermoregulatory devices are waterproof and breathable, which allow thermogenerators such as hot packs and cold packs, to remain dry while still allowing air flow such that thermogenerators using air-activated chemical reactants remain active. Thermoregulatory devices are particularly useful with garments maintaining the thermogenerators close to the body's core where they will be most effective. The thermoregulation systems advantageously allow a user to selectively position thermoregulatory devices in different regions of the user's body to self-regulate core body temperature.

This invention provides a thin and discreet coolant device, and single and multiple unit dispenser containers containing the same. The coolant device comprises a first packet being comprised of a waterproof or water-resistant material containing water therewithin and further comprising a fold and further adapted to have a selectively permanent connection between external and internal layers of said fold, such that upon applying a force to laterally extend the ends of said packet, a rupture of said first packet occurs allowing for the leakage of the water contained therewithin. The coolant device further comprises a second packet which encases said first packet, comprising an exterior and interior layer, wherein said interior layer is comprised of an absorbant material and said exterior layer is comprised of a waterproof or water-resistant material and wherein an amount of powdered urea is located within an interior of said second packet. Upon lateral extension of the sides of the second packet, a rupture of said first packet occurs allowing for the leakage of the water contained therewithin and its exposure to said urea located within said second packet, which exposure results in an endothermic reaction resulting in an outer surface of said second packet becoming cooler to the touch than an outer surface temperature prior to said rupture. Use of the coolant devices to provide cooling to a skin surface on demand is described, as well.

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.

An instant cold therapeutic apparatus, comprising: at least one squeezable packet (1) associated with the apparatus, wherein the packet is gently squeezed by a user, a first burstable pouch (2) present inside the packet filled with first non-toxic reactant and a second burstable pouch (3) available inside the packet having a second non-toxic reactant, wherein the pouches present inside the packet include two non-toxic reactants, which react to produce cooling sensation at the infected portion of the user body.

A cerebral protection system generally includes an array of cold packs, an insulating cover, and optionally a set of trays. The cold pack contains two reactive materials separated by a rupturable membrane. When the first reactive material and the second reactive material are mixed, an endothermic reaction occurs. The system can be used to induce hypothermia in selected regions of the brain when used. The system can be used to treat conditions including concussion, traumatic brain injury (TBI), heatstroke, cardiac arrest, respiratory arrest, anoxic brain injury, ischemic stroke, transient ischemic attack (TIA), or hypoxic ischemic encephalopathy.

The invention disclosed herein generally relates to a methods and devices for personal care. The invention includes methods and devices for ameliorating microbial infections and for capture and disposal of menstrual fluid.

The Self-Adhesive Cold Pack has a sealed impervious pocket also known as the reaction chamber that contains a cooling agent or material, that when mixed cause an endothermic reaction to occur. Affixing tabs are attached lengthwise to the top and bottom edges of the pocket. The affixing tabs are designed to adhere the cold pack to the skin of the patient or person during treatment.

Systems and methods are disclosed that relate to a stabilization and cooling apparatus having a stabilizing structure with at least one inflatable chamber, the stabilizing structure configured to become semi-rigid upon inflation of the at least one inflatable chamber. A cooling structure is integrated with the stabilizing structure and includes a single-use cooling element and a thermally conductive material in thermal communication with the single-use cooling element. The apparatus also has an actuator configured to cause inflation of at least one inflatable chamber.

A heat pack using supercooled aqueous salt solution that resists premature activation at low temperatures is disclosed. The heat pack comprises two sheets that are bonded together to form a laminated sheet. The heat pack has a first and second compartment. A frangible seal separates the two compartments. One of the compartments contains a supercooled aqueous salt solution. The salt solution contains 15 to 25 percent glycerin by mass.

A modular kinesiology or physio tape adapted to produce heating or cooling. The tape includes a layer of material having a chamber for retention and release of a removable packet of cooling or heating material and a mechanism for securing the layer directly onto skin of a user. The removable packet of cooling or heating material has dimensions optimized for manual insertion into and removal from the chamber. Preferably, the material is flexible and includes an adhesive for securing the layer to the skin. The material has a first surface for contacting skin, a second surface parallel to the first surface for receiving and retaining the removable packet and an edge between the first and second surfaces. In one embodiment, multiple slits are provided in the second surface having dimensions adapted to receive and retain said packet. In yet another embodiment, a heating packet is implemented with a button/coin type battery circuit with an optional mechanism for controlling the generation of heat thereby.
