(54) Therapeutic water bed


(57) A therapeutic water bed with a top surface adjustable between a completely soft condition for relief from pressure for patients who lie in the same position for a considerable time to a firm condition for nursing care and other treatments of the patient. The therapeutic water bed comprises a water container (1) open on top, with a cover (4) of a flexible,, elastic material and an additional detachable cover (4a) of the same material, which can be exchanged with other covers of a different thickness for a possible adjustment of the double cover (4, 4a) to a patient's physical condition and/or weight. An inflatable air mattress (4) with a flexible, elastic top and a flexible, inelastic bottom is devised under the top cover (4). The bottom is attached by means of inelastic tape loops (8a) and stretching tapes (8) to a stretching device (7, 8) for stretching the bottom (5a) and thereby regulating the softness/firmness of the top surface (the double covers (4, 4a)). Said attachment and stretching of the bottom (5a) of the air mattress (5) prevent the occurrence of waves and undesirable movements in the top surface of the water bed.
