In some embodiments, the insulated purse will have at least two pockets; one for containing a frozen gel pack, and the other for containing a soft cover for the gel pack. The purse can be held in a closed configuration by integrated fastening hooks or other closures. The insulated purse may be constructed of a variety of materials, such as leather, vinyl, or plastic; the gel pack cover may be constructed of a variety of materials, such as fleece, wool, cotton, silk, terry cloth, or chenille, among others.
Abstract:
A microclimate management sheet, for placing against a person's body, includes a flexible generally fluid impermeable first layer, a flexible generally fluid impermeable second layer with a gas permeable region for facing a patient's body. The first layer is joined with the second layer in a manner to form a chamber between the first layer and the second layer. An inlet operative to be in fluid communication with a supply of gas and in fluid communication with the chamber is provided for delivering a gas to the chamber, with the gas permeable region for directing the gas the patient's body.
Abstract:
A watertight container has a container body, and first and second elongate locking elements. The container body includes a side wall that defines an interior and extends to a perimeter that defines an opening to the interior of the watertight container. The perimeter of the container body has a first portion and a second portion, the first portion has a first plurality of apertures, and the second portion has a second plurality of apertures. The first and second elongate locking element are rigid and adapted to abut the first and second portions, respectively, of the perimeter of the container body. A plurality of fasteners removably fasten the first and second elongate locking elements together, such that the first and second elongate locking elements together seal closed the opening of the container body.
Abstract:
The present invention relates to a flexible plated cooling pack for headwear and a method for making the same that is capable of providing a sufficient cooling effect with a small amount of coolant, not causing worry about leakage of the coolant, and providing a cushion effect without a volume variance regardless of many uses, as well as the cooling effect.The flexible plated cooling pack has an inner and outer synthetic resin film sheet bonded each other and a coolant filled therein, wherein the outer synthetic resin film sheet has a shape respectively corresponding to a piece of the crown portion and a sweatband and the coolant is always maintained in at least a gel state. The flexible plated cooling pack may be disposed in an inner portion of the crown portion and the sweatband of the headwear or may be inserted in a pocket formed at an inner portion of the crown portion and the sweatband of the headwear.
Abstract:
A microenvironment system for use with a heat transfer fluid includes a microenvironment structure and a fluid handling apparatus. The microenvironment structure defines a flow passage to receive a flow of the heat transfer fluid therethrough. The fluid handling apparatus is adapted to provide a flow of the heat transfer fluid through the flow passage. The fluid handling apparatus includes a gas driven pump and a supply of a phase change material (PCM). The gas driven pump is operable to force the flow of the heat transfer fluid through the flow passage. The supply of the PCM is convertible from a solid and/or liquid phase to a gas phase to provide a pressurized drive gas. The fluid handling apparatus is configured to drive the gas driven pump using the pressurized drive gas from the supply of the PCM.
Abstract:
A system for cooling fluid to cool and condition a race cart driver's suit, helmet or seat. The system includes Peltier effect thermoelectric coolers sandwiched to form water and air passages to cool liquid in use in a suit, helmet or seat and to expel waste heat. A thermoelectric cooler for cooling a driver worn device including a thermoelectric cooler having a first heat exchanger, an inlet for supplying one side of the first heat exchanger, and an inlet for air supplying an opposing side of the first heat exchanger. A pump for moving liquid from a reservoir on the TE cooler with a first heat exchanger to a second heat exchanger worn by a driver. A quick release device to detach the TE cooler from the second heat exchanger with a single motion depressing a single bar releases two quick connects.
Abstract:
A heat transfer fluid pathway is provided driven by a pump which feeds the heat transfer fluid through a vest and cap or other heat transfer garment, where the heat transfer fluid draws heat away from the body of the wearer. A drinkable heat sink material is located within a removable cartridge located within a heat exchange pouch. The heat transfer fluid passes from the heat transfer garment to the heat exchange pouch where heat drawn from the wearer is transferred to the heat sink material within the cartridge. A temperature control valve is provided along with a bypass line so that an adjustable amount of the heat transfer fluid is routed to the heat exchange pouch for temperature control. A supply of elevated pressure air is optionally provided to maintain optimal contact for efficient heat transfer within the heat exchange garment and the heat exchange pouch.
Abstract:
A system for cooling an auxiliary device having a main housing with at least one canister port, at least one fluid manifold mounted within the housing and in communication with the port, and a removable dry ice canister inserted in to the fluid manifold. Connected to the fluid manifold is a fluid line and connected to the canister is an air pressure line. Both the air pressure and fluid lines are connected to the pump. As the dry ice melts, it cools the fluid and creates pressure that activates the pump to pump fluid to the auxiliary device and back to the manifold for subsequent cooling.
Abstract:
A vest including inflatable tubes or chambers which receive cool air from a blower box. The vest includes an outer surface and inner surface, the two surfaces joined to define a multiplicity of tubes. The tubes carry jets which may vent cool air, received from a remote cool air blower box. The jets will ventilate the skin of the wearer both where it is exposed and where the skin is covered by the garment itself.
