Abstract: The invention relates to an applicator for use with a device for treating subcutaneous lipid-rich cells by cold treatment, wherein the applicator (1) comprises a contact surface (2) that is formed as a surface (3) of a solid treatment plate (4) made of aluminum or another material having good heat conductivity. The invention further relates to a device for treating subcutaneous, lipid-rich cells by cold treatment comprising a heat transfer circuit and an applicator (1) through which a heat transfer medium (6) flows for treating a live body. The device consists of a refrigeration device (30) for providing the heat transfer medium (6) having a specific temperature and connecting supply lines (29) to the applicator as well as a compensator (31) that compensates the weight of the applicator.

Abstract: An adapter for a contact rail having electrical conductors and grooves provided on opposite surfaces thereof including a housing including, two lateral legs forming a recess therebetween and moveable away from each other between an open and a closed position. Electrical contacts are provided in the housing at the opposite sides of the recess and positioned for engaging with electrical conductors of the contact rail with the contact rail placed between the legs in the closed positon. At least one of the lateral legs can be moved along a straight line into a closed position such that holding elements provided on the legs engage grooves on the contact rail and the electrical contacts engage the electrical conductors of the contact rail.
