Claims

[Scope of claim for utility model registration] Irradiation control circuit that controls laser beam irradiation;
A constant current circuit that stabilizes the signal from the irradiation control circuit, a semiconductor laser that causes a plurality of semiconductor chips to emit laser beams based on the signal from the constant current circuit, an addition circuit that adds up the irradiation states of the semiconductor laser, and a circuit that prevents contact with the human body. A probe circuit formed by a touch switch circuit that is sensed and turned on, and a manual switch that starts outputting the laser beam via the irradiation control circuit.
A first memory circuit that stores the state, and a second memory circuit that stores the ON/OFF state of the stop switch to be stopped.
a first AND circuit comprising a memory circuit and connected to both the first and second memory circuits for calculating the AND of both the manual and stop switches;
a second AND circuit that takes a logical product of both second memory circuits and the touch switch circuit;
and a second AND circuit;
A time display circuit equipped with an irradiation time indicator lamp that cumulatively displays the irradiation time of the laser beam in an additive manner depending on the N state or ON state signal of the touch switch circuit; an irradiation time setting circuit that stores a preset setting time; A time calculation circuit that includes a preset counter that adds up the irradiation time to a set time and stops the laser beam irradiation when the irradiation time of the laser beam matches the addition time of the preset counter; A photo sensor that converts the amount of laser beam into an electrical signal, a comparator that uses the amount of light converted into the electrical signal as a received light value and compares it with a preset standard value of the laser beam, and depending on the comparison result whether it can be used or not. a power check circuit that includes a display unit that displays whether or not the irradiation laser beam output has been decreased; A laser medical device capable of checking the output of a laser beam emitted from a probe circuit using a control circuit.
