ABSTRACT:
A nurse's call system is constructed for use in hospitals, nursing homes and the like wherein classified groups of services are provided including (a) services lowest in importance rendered by a nurse's aide; (b) services of greater importance rendered by a nurse or a doctor; and (c) services of greatest importance rendered by an emergency unit or team including units to deal with cardiac arrest, hemorrhage, shock, suffocation, oxygen requirements, and the like. The call system comprises a luminaire apparatus including a call lamp located at the nurse's call station, electrical circuitry connecting the call lamp with a remotely located patient's room, and a portable call box located at the patient's room at a patient's bedside. The call box is provided with a plurality of switches for energizing the call lamp and producing light signals of differing light characteristics which are arranged or coded in an ascending order of importance and which are correlated with the classified groups of hospital services noted. As each light signal is received at the nurse's call station, the characteristics of the coded light emission indicates the order of magnitude of urgency desired in obtaining a signal response, as well as the specific assistance a patient may require.
