tubular sleeve apparatus primarily designed to surround a part of the body, and applying pressure to it, in order to establish and maintain, in a peripheral region of the body part with a field of fluid and gas depletion and / or to include a ban on all of the support and / or pressure and / or to mechanically join the part of the body.the sleeve has substantially annular chambers (4) arranged one after the other in the axial direction of the sleeve and close to one another, of which the walls (41) are formed of flexible material and primarily elastic.the chambers are enclosed by a common outer peripheral pressure cell (3) extending in the axial direction of the sleeve and provided with coupling devices (12, 13) to pressurize the cell (3) with a pressure medium from a pressure source extern (14).the pressure cell has a wall (5) turned towards chambers (4) and connected to the valve device (6) for the operation of these devices, part of the valve, the latter being arranged to open and close communication devices. rmettant passing a medium pressure between adjoining rooms.during the use of the sleeve, the pressure cell (3) receives an internal pressure increase valve opening force of the device (6) in the feed chamber (4) in the middle of the pressure. pressure on the part of the body, the sleeve is expanded mainly continues in the area.
