PURPOSE:To select necessary laser according to a medical caring purpose and to improve safety and facility by controlling a plurality of laser medical caring devices by means of a control circuit to detect the ON and OFF states of a touch switch and a control circuit to stop irradiation with laser from the laser medical caring device when the touch switch is brought into an ON-state two or more times. CONSTITUTION:Laser elements 11a, 11b, and 11c are connected to drive circuits 13a, 13b, and 13c. By sensing contact of a finger by means of touch switches 12a, 12b, and 12c mounted on a hand piece, the drive circuits 13a, 13b, and 13c are turned ON. Touch switches 14a, 14b, and 14c are connected to the drive circuits 13a, 13b, and 13c, respectively, and the touch switches 14a, 14b, and 14c are connected to a control circuit 16. The control circuit 16 turns OFF a relay switch 15 when two or more of the touch switches 14a, 14b, and 14c are brought into an ON state. The relay switch 15 is connected to a power source part 18 in a state to be in series to a foot switch 17. This constitution simply and safely uses a plurality of laser medical caring devices. |
