As shown in the figure, the circuit diagram of the bone hyperplasia treatment instrument. Close the power switch S1, the mains is added to the primary of the power transformer T through the switch S1, the fuse FU, and the T secondary output 40V, 7V two sets of voltage. The 40V AC voltage is rectified by a rectifier bridge UR2 composed of 4 diodes, and the output is pulsed to the input terminal of the timer PT. When preparing for treatment, turn the timer PT, set the treatment time, the timer PT normally open contact is turned on, the UR2 output DC ripple voltage is filtered by the capacitor C4, and after the IC2 voltage regulation, the output is stable +24V DC, the relay K2 is subjected to Electric suction, its normally open contact K2-1 is connected, and +24V DC is limited by the current limiting resistor R3 and then output to the lesion by the electrode piece for treatment. Adjusting RP1 adjusts the therapeutic output intensity. Another set of 7V AC power supply, rectified by UR1, filtered by capacitor C1, output DC power supply, power indicator LED1 is on, and the normally open contact IC2-1 is connected to supply power to relay K1. K1 receives power, often The open contact K1-1 is connected to the self-protection. At this time, since the K2-2 has been disconnected, the music alarm circuit temporarily does not work. After the treatment time is reached, the timed PT normally open contact is disconnected, and the treatment electrode piece stops working due to power loss. At the same time, K2 loses power, K2-1 is disconnected, K2-2 is turned on, and UR output DC power is supplied to the alarm circuit via K1-1 and K2-2. The alarm circuit is powered, and a music alarm sounds to remind the patient that the treatment is over. This is how it works.
