This is especially true in the case that used the underspring invention for pain therapy becomes. From the control and the stroke and / or the lifting or lowering speed of the lifting members can be controlled individually. It is also conceivable to arrange the lifting organs or equivalent air springs as support or stimulation elements on the bed surface or even to assign the blanket. It is also possible to design the freely programmable control of the lifting members so that they allow feedback.
- physiological data of the person lying on the mattress are measured and the measured values are used by the control in order to control the movements of the lifting organs in a targeted manner.
- the measurement of, for example, the movement of a person lying on the mattress can be done by determining the internal pressure in the bellows or the air supply to the bellows.
- the control makes it possible to move the mattress by the lifting members both periodically and irregularly, in particular quasi-periodically, by a corresponding program selection.
- other signals can be included in the control, for example acoustic signals, in particular music signals.
- Visual signals for example color signals, can also be processed by the controller if required.
- the spring support according to the invention serve for stimulation, in particular basal stimulating care of unconscious, ventilated, disoriented, somnolent, traumatic brain traumatized, patients with hypoxic brain damage, Alzheimer's, in the mobility restricted patients, disabled and / or premature babies.
- the stimulation may be somatic stimulation, visibular stimulation, vibratory stimulation, oral stimulation, auditory stimulation, tactile-haptic stimulation, visual stimulation, and combinations of the aforementioned types of stimulation.
- the consequence of the stimulation is above all the elimination of an irritant poverty.
- the stimulation by targeted movement, especially the mattress is used in particular for decubitus prophylaxis and / or decubitus therapy.
- the stimulation also serves to assist in pain therapy and / or to promote perceptions.
