The electrodes of a mercury switch, which is included in an alarm module that is attached to the patient's thigh, close to produce an electric signal whenever such inclination exceeds a preselected threshold angle. Such signal activates an alarm-generating electrical circuit to produce an alarm with a distinctive sound to provide notice to attending personnel of the possibility of impending injury to the patient.Field of SearchTilt | |
