An apparatus (10) for supporting a patient during a medical procedure includes a bead bag (18) that is filled with compressible beads (20) and that forms a lower layer of the apparatus (10). The apparatus (10) also includes a layer of foam material (30) that is located above the bead bag and an air cell grid (36) that has a plurality of inflatable air cells (38). The air cell grid (36) forms an upper layer of the apparatus (10) and provides a soft surface upon which the patient lies. The bead bag (18), when subjected to a vacuum, becomes rigid for supporting the air cell grid (36) against the patient for helping to maximize a surface area of contact between the patient and the apparatus (10).

L'invention concerne un dispositif (10) destiné à porter le patient au cours d'une intervention chirurgicale. Ce dispositif (10) comprend un sac de billes (18) rempli de billes compressibles (20) qui forme la couche inférieure du dispositif (10). Ce dispositif (10) comprend également une couche de matériau alvéolaire (30) placée au-dessus du sac de billes ainsi qu'un réseau de poches d'air (36) constitué d'une série de poches d'air gonflables (38). Le réseau de poches d'air (36) forme la couche supérieure du dispositif (10) et offre une surface souple de couchage sur laquelle s'étend le patient. Sous l'effet d'un vide d'air, le sac de billes (18) se rigidifie et sert de support au réseau des poches d'air (36) qui s'appliquent alors contre le patient. Ceci permet d'augmenter au maximum la surface de contact entre le patient et le dispositif (10).
