Load signaling device for a patient's foot

摘要

A device for providing an acoustic signal to a patient when a predetermined load is placed on the patient's foot comprises a fluid filled control means with a first bladder underlying the patient's foot and a second bladder as interconnected via a flexible tube. The second bladder is adapted to actuate a signaling means comprising a resiliently supported and biased click spring that provides an audible click noise when actuated by the second bladder of the control means at a predetermined pressure of the liquid corresponding to a predetermined load as placed on the patient's foot.
