Device intended to act on a surface area of a person's skin in order to produce a subcutaneous effect as well in the near part of the person's body, where the device contains at least the following elements: - stimulation means with a stimulation surface on one side whose dimensions correspond to the dimensions of the relevant surface area of the skin of the person on whom the device must act; - one or several stimulation elements (19,20) distributed over the stimulation surface and each formed of a hollow compartment that can be pumped full with a medium to bring it into an expanded state and that can be pumped out or sucked out again so as to bring it into a constricted or folded state; - pumping means for supplying and discharging medium to or from the relevant compartments; - tightening means for tightening the stimulation means against a person's body, whereby the device is designed as a carrying strap that is intended to be placed around a person's abdominal region, where the stimulation means are located in a central section of the carrying strap, where a surface section of the stimulation surface is formed of a section of at least one of the stimulation elements (19,20) and one or more intermediate surface sections of the stimulation surface extending between the contours of this stimulation element (19,20), where this stimulation element (19,20) and the intermediate surface sections are shaped in such a way that, when the stimulation means are applied to a person's skin with the tightening means, and one or several of the aforementioned stimulation elements (19,20) is brought in the expanded state, the person's skin will be subjected to a positive pressure at the expanded stimulation element (19,20), and to an underpressure or negative pressure in one or more intermediate zones, wherein the aforementioned at least one stimulation element (19,20) is formed of a hollow compartment with a closed contour that entirely encloses the one or more intermediate surface sections of the stimulation surface, characterised in that when the above-mentioned stimulation element (19,20) has been expanded by filling it with medium, sections of the stimulation element (19,20) adjacent to the skin will exert a pressure on the skin, and other opposing sections of the stimulation element (19,20) will undergo a movement away from these adjacent sections, wherein edges of at least one zone of one or more of the intermediate surface sections which connect to contours of the stimulation element (19,20) are also subjected to a movement in this movement away, and wherein this zone of the intermediate surface section concerned forms an airtightly sealed zone since an airtightly sealed, circular strip or edge remains around the zone between the stimulation surface and the skin that is composed of sections of the stimulation element (19,20) in such a way that, during the aforementioned movement away an underpressure is created between the aforementioned sealed zone and the skin that has a sucking effect on the corresponding part of the skin. - stimulation means with a stimulation surface on one side whose dimensions correspond to the dimensions of the relevant surface area of the skin of the person on whom the device must act; - one or several stimulation elements (19,20) distributed over the stimulation surface and each formed of a hollow compartment that can be pumped full with a medium to bring it into an expanded state and that can be pumped out or sucked out again so as to bring it into a constricted or folded state; - pumping means for supplying and discharging medium to or from the relevant compartments; - tightening means for tightening the stimulation means against a person's body,
