Abstract:
A device for providing an acoustic signal to a patient when a predetermined load is placed on the patient's foot comprising:a resilient foot pad filled with a fluid and serving as a pressure sensor for the patient's weight for sensing the load exerted via the patient's foot to the foot pad; anda fluid line connecting the resilient foot pad to a pressure responsive means communicating with the liquid and adapted to actuate a signaling means at a predetermined pressure of the liquid corresponding to a predetermined load when placed on the patient's foot;wherein said signaling means comprises a click spring having a deformable bulge and being resiliently supported such as to supply an audible click noise when actuated by said pressure responsive means whereby the click noise is obtained by a transient deformation of the bulge whenever the click spring is leaving its rest position and is again returning to the same.
