ABSTRACT:
An improved call system has a signal sending apparatus, a message receiving station located at a distance from the sending apparatus, and signal generating means located at the receiving station. The signal sending apparatus includes a call box for selectively energizing the generating means and producing a set of coded signals, each of which, when in communication with the receiving station, calling for a response which is determined by the specific message characteristics of the communicating signal. The signals may be generated in the form of light, sound or both, controlled in duration and intensity, and communication may be through electrical conductors, by radio, by telephone and other means.
In one specific aspect the message receiving station may be a nurses call station in a hospital and the call box may be operated by a person in need of assistance in a hospital room or other area. The call box includes switch means for energizing the signal generating means and producing a set of coded signals which are prioritized in terms of urgency of need and the needee may select a specific signal calling for (A) a hospital aide, (B) a nurse, or (C) emergency treatment, thus substantially increasing efficiency of use of hospital personnel as well as enhancing patient's security.
