A LIGHT SUPPLY DEVICE FOR AN ENDOSCOPE

摘要

An endoscope is connected to a light supply device through a universal cord. The light supply device includes an illumination lamp for emitting a diagnostic light and a stroboscopic tube for emitting a photographic light. The diagnostic light and photographic light are selectively conducted to the endoscope. A control section for controlling the operation of the flash tube includes a patient circuit, an intermediate circuit and a primary circuit. Optoisolators are provided to connect the intermediate circuit to the patient circuit as well as to the primary circuit while electrically isolating the intermediate circuit from the patient circuit and from the primary circuit.
