The invention relates to a device reversibly connectable to the human body for refrigerating a part thereof. The device of the present invention comprises a casing including a plurality of cavities which are mutually separated and each accommodating a given amount of thermal gel. The casing is connected to a first band by means of a plurality of press studs. The band can be wound about a part of the human body so that the casing containing the thermal gel is in contact with said part of a human body. The band comprises a buckle at a first end. By inserting the band into the buckle from a second end opposite to the first end, the band can be closed as a ring and fastened on said part of a human body. The band is kept wound on said part of a human body by means of Velcro. In a first alternative embodiment, the device of the invention comprises a second band connected, at the ends thereof, to the first band so as to form a ring in which a foot can be inserted. In such a variant, the device of the invention can be specifically used to cool the back of a foot. In a second alternative embodiment, the device of the invention comprises a shell which is substantially shaped as a shin-pad and to which the casing containing thermal gel is reversibly connected at the concavity thereof. In such a variant, the device of the invention can be specifically used to cool the front part of a leg. In a third alternative embodiment, the device of the invention comprises a helmet to which a plurality of said casings containing thermal gel are reversibly connected at the concavity. In such a case, the device of the invention can be specifically used to cool the head.La présente invention concerne un dispositif pouvant être relié de façon réversible au corps humain pour réfrigérer une partie de celui-ci. Le dispositif de la présente invention comprend un boîtier comprenant une pluralité de cavités qui sont mutuellement séparées et qui reçoivent chacune une quantité donnée de gel thermique.
