ABSTRACT:
Readiness for operation of laser medical instruments or of flash generators for ophthalmological instruments is indicated in such a way that the readiness signal is perceptible only to the physician and not to the patient being operated upon. There is a mini-earphone to be worn in an ear of the physician. The conventional readiness signal, if of the optical kind, is converted to an audible signal delivered to the earphone of the physician. A photodiode responsive to the optical signal is part of the conversion system, which also includes an audiogenerator and an amplifier. If the conventional readiness signal is of the audible kind, the loudspeaker is rendered inoperative and a sound signal is produced in the earphone. In addition to the advantage that the readiness signal is perceptible only to the physician and not to the patient, a further advantage is that the physician does not have to turn his head or shift his gaze from the desired concentration on viewing the operating area, in order to see a signal light, as is necessary in prior art signals of the optical variety.
