UNITED STATES PATENT OFFICE 2,288,745 HEAT EXCHANGE DEVICE Theodore Reginald Sammis, Stewart Manor, Long Island, N. Y. Application March 3, 1941, Serial No. 381,450 1 Claim. (Cl. 128——403) This invention relates generally to a device and method for assisting a person to keep comfortable in warm or hot weather. The main object of my invention is to pro vide a device and method for assisting the body to dissipate excess heat in a simple and effec tive manner. This object involves furnishing Mounted removably in the bag is a sponge rubber container or sack M. This sack is slitted along a portion of its periphery which opens into a chamber or compartment I5 inside of the sack. In the chamber or compartment 15 is placed a cake or cube l6 of a suitable refrig erant, such as dry ice. My improved method contemplates that the improved device be worn in pairs on opposing device. Another object is to provide a device of this 10 members of the body; that is, one is placed on each arm, or on each wrist, or on each thigh, kind that is sanitary. or on each ankle, etc., as desired, but may be Another object is to provide such a device a cool environmental factor in the form of my used singly on any of various body surfaces. and method that is safe for general use, incor porating proper insulation of the dry ice or other However, I prefer to place my improved device refrigerant. on the arm I‘! as illustrated in Fig. 1. A further object is to provide such a device that may be used without harm to the body or clothing. In such case, the device is placed on the upper arm im mediately above the eminence caused by the bi ceps brachii. The bag In is placed on the inside of the arm approximately over the area under Another object is to provide such a device and method that adjusts itself to the temperature 20 which courses the brachial artery. I have found from experiment that my device of the body in nowise disturbing the balance be does not lower the body temperature even a tween thermogenetic and thermolytic functions. fraction of a degree; that the use of the device Other objects and advantages will appear from causes no imbalance between the thermogenetic the description to follow taken in connection with centres and the thermolytic centres of the body, the accompanying drawing in which-— and that my improved device merely assists in Fig. l is a proximal view of a right arm of a the work of the thermolytic function, literally person on which is mounted a device embodying absorbing some of the excess heat from the blood my invention. stream through the super?cial tissues of the body Fig. 2 is a front view of the improved device, at the point or points where the device is worn. parts being broken away for the sake of clear I claim: A device for dispersing excess heat of the Fig. 3 is a sectional view on the line 3--3 of human body including a fabric envelope having Fig. 2. an opening at one end thereof, an integral fold- ' Fig. 4 is a perspective view of the sponge rub able flap for closing said opening, a sponge rub ber sack. ber member having flat sides and a circular pe Fig. 5 is a sectional view of the sack shown riphery and. having an interior compartment be in Fig. 4 on the line 5--5 of Fig. 4. tween said sides With an entrance on the circular In carrying out my invention I provide a fab periphery, said compartment being adapted to ric bag or envelope II] to which is suitably fas tened an elastic arm band II.
