Hydrostatic bed
As a hydrostatic bed, Nayade or Arnott's bed, a nursing bed designed by Scottish physician Neil Arnott, circa 1830, for the prevention of the wounding of bedridden patients. The bed was used in various English hospitals in the middle of the 19th century.
The bed was described in 1833 in the general repertory of the entire German medical-surgical journalism as a water-filled, tub-like box or saddle covered with a wide rubber blanket. A multi-layered ceiling was then placed as a mattress and a head pillow. It is similar to the later developed waterbed. On this patient bed, which is also referred to as a floating mattress, the local pressure load is reduced to the patient's skin, thereby avoiding decubitus ulcers and curing other skin injuries, for example by wound firing. In addition, Arnott recommended to use the bed without bedding for other patient groups. He thought, among other things, about the possibility of cooling febrile patients in the tropics.
