  • the weight of the person acts to straighten the person's spine from its more natural curvature under the influence of gravity.
  • the curvature of the lower back tends to be increased from the natural curvature if the person slumps .
  • the back muscles and tendons perform work to counteract gravity and to maintain a natural curvature.
  • the musculature is insufficient to maintain the natural curvature of the back, especially the lower back.

  • a person when a person is required to remain on their back on a table for a substantial period of time, it is important that the person remain stationary and that they are not able to roll from side to side. It is also important that if the person's back is provided with a support to maintain a natural curvature, that the support not interfere with the hospital procedure.
  • the invention is directed to a support for maintaining the natural spinal curvature of a person that satisfies the above mentioned objects.
  • the back support comprises an inflatable chamber, a means for stabilizing the person against movement when the inflatable chamber is pressurized and positioned between the person and a flat surface, and a means for adjusting the amount of gas, and thus the pressure of the gas, within the inflatable chamber.

  • Chamber 120 may be partially or completely separated from chamber 130 by a means for restricting gas flow between chambers.

  • chamber 130 is partially restricted by a crease from chamber 120 and receives substantially less air than chamber 120.

Inflation ceases when the back support is judged to be comfortable by the supine individual. Or, the back support is inflated until it substantially fills the space between the curve in the back of the individual and the table.
  • chamber 130 is substantially flattened and frictionally engages the surface of the table 300. The amount of air in chamber 120 depends upon the weight of the individual lying on the chamber 120.

Abstract

L'invention concerne un support destiné à maintenir la courbure vertébrale naturelle d'une personne, en particulier lorsque la personne est allongée sur une surface sensiblement plane, telle que par exemple, une table d'opération, et son mode d'utilisation. Le support dorsal (10) comprend une chambre gonflable (3), un moyen destiné à stabiliser la personne afin qu'elle soit immobile lorsque la chambre gonflable (3) est sous pression et positionné entre la personne et la surface plane, ainsi qu'un moyen destiné à régler la quantité de gaz, et ainsi la pression du gaz régnant à l'intérieur de la chambre gonflable. Le moyen destiné à régler la pression comprend un système de gonflage (38), un système de dégonflage (36) et un système d'alimentation en gaz (34) sous pression de la chambre gonflable (3). Dans un mode de réalisation, une seule chambre gonflable est rattachée à une couche (5) stabilisant le support dorsal (10) et la personne.
