Abstract: Inflatable positioning equipment in the shape of an elongate roll for positioning a patient during a renal surgical procedure is provided. The positioning equipment includes: an inflatable covering which defines the external dimensions of the positioning equipment; a first air chamber system on the inside of the covering, which can be filled with air for inflating the covering; and a second air chamber system on the inside of the covering, which can be filled with air to inflate the covering. The second air chamber system is fluidically separated from the first air chamber system such that a leak in one air chamber system does not result in air loss in the other air chamber system.

Abstract: Inflatable positioning equipment (10) in the shape of an elongate roll for positioning a patient during renal surgical procedure, the positioning equipment being provided to be placed at an appropriate location on a surgical table, to serve as a support for a body part of a patient such that the renal area of the patient, is brought into a stretched position necessary for the renal surgical operation, wherein the positioning equipment comprises the following: an inflatable covering (12) which defines the external dimensions of the positioning equipment; and a first air chamber system (22) on the inside of the covering, which can be filled with air for inflating the covering (12); characterized in a second air chamber system (24) on the inside of the covering (12) which can be filled with air to inflate the covering (12), and in that the second air chamber system (24) is fluidically separated from the first air chamber system (22) such that a leak in one air chamber system does not result in air loss in

Abstract: A headrest for a patient-bearing surface, having an approximately horseshoe-shaped form and comprising a central section (14) for supporting the back of the head or the forehead, the bearing surface thereof being at least approximately spherical shell-shaped, also comprising two side sections (16) which are arranged at a distance from each other and whose bearing surfaces conform at least approximately to a common cylindrical surface whose axis is parallel to a symmetrical line (20) of the headrest extending between the side surfaces (16). A cheekbone support (18), which protrudes in the direction of the other side section (16), is provided on each side section (16).
