Title: Light source device for pharynx stroboscope
Inventor: OGOSHI ISAO
IPC: A61B5/11
Filed: 1989-08-08
Abstract: PURPOSE:To obtain the light source device of a phargnx stroboscope which is safe and effective by forming the light supplied from a light source to the intermittent light by applying a trigger voltage synchronized with the vibration of the vocal chords into a liquid crystal shutter. CONSTITUTION:A patient is allowed to make voice, allowing a contact microphone 1 to contact the skin at a part close to the vocal chords of the patient, and only the fundamental waves are taken out by a wave form shaping circuit 2 by picking up the vibration of the vocal chords by the contact microphone 1, and the pulses synchronized with the fundamental waves are obtained. After the phase of the pulse is shifted by a phase shifting circuit 3, a trigger voltage is generated by a trigger circuit 4, and applied onto a liquid crystal shutter 5. Since the continuous light transmitted from a light source 6 passes through the liquid crystal shutter 5 only the time when the trigger voltage is applied, the light after the passing through the liquid crystal shutter 5 forms the intermittent light. Since the intermittent light is synchronized with the vibration of the vocal chords of the patient, the vibration of the vocal chords seems to stop, when the intermittent light is irradiated onto the vocal chords.
