(54) PULSE GENERATOR FOR LIGHTING

,, . one , . .;,:

The invention relates to medical technology.:.

A device is known, consisting of a power source and an irradiator, which makes it possible to treat with monochromatic incoherent red light in continuous mode 1e l) 2.

The main drawback of these devices is that monochromatic incoherent red light is emitted by a net stream at a constant power, which leads to low generator efficiency, and the light treatment dose is adjusted by means of a turnips time.

The aim of the invention is to increase the efficiency of the generator.

This goal is achieved by introducing a pulse counter, a capacitor unit, and a control unit connected between the power source to the pulse generator for light therapy, which contains a power source and an irradiator.

Both by the central unit and connected to a block of capacitors, which is connected to the blast directly, and to the source tshtank through the counter: pulses.

Fig. 1 shows a block diagram of a pulse generator for light therapy; in fig. 2 - its basic scheme.

The generator contains a power source 1, a pulse counter 2, a capacitor unit 3, a control unit 4, an irradiator 5.

The block 3 of capacitors consists of electrolytic capacitors 12-18 with a total altitude of 560 microfarads and switching toggle switches 19-24, with the help of which

A light impulse control unit 4, as shown in FIG. 2, consists of a generator readiness indicator for issuing a light pulse containing a series of resistor 26, a ion lamp 27 and a time circuit consisting of resistors 28-31 and a capacitor 32 / which control the ignition time of the thyratron 33, which are pulsed into the anode peep a transformer 34 that ignites the xenon lamp 25 of the illuminator 5. The mode of operation of the generator is determined by the position of the switch 35.

 The pulse generator for light blinding works as follows.

The mains plug is plugged in, then the capacitors 12-18 are turned on in the required combination. In position A, switch 35 turns on & supply voltage and starts charging capacitor 12 and switched on capacitors 13-18. The xenon lamp 25 is automatically ignited when the respective capacitors are charged to a certain value. For this purpose, a primary-free thyratron 33 is connected to the primary winding circuit of the pulse transformer 34, which transmits the charge current to the capacitor 32. The voltage on this capacitor is part of the common voltage, and its charging time depends on the position of the potentiometer slider 29, i.e. it determines the time of ignition of the thyratron 33 and, therefore, of the xenon lamp 25. If the condensers 13–18 are not turned on, the capacitor 12 remains on and the flash frequency of the xenon lamp 25 reaches 20–25 Hz at low power.

In some cases of patient therapy, it is necessary to charge storage capacitors until the voltage of the power source and at the right time give a light pulse. For this purpose, the position P (manual) of the switch 35 is used. A light pulse arises at the moment the knob 35 returns to the middle neutral position. The number of pulses is ret-isted by counter 2. Upon completion of the operation, switch 35 is placed in the middle position. The total weight of the pulse generator for light treatment is 2 kg.

The pulse generator for light therapy increases the efficiency and therapeutic effect, allows for individual treatment of patients in a pulsed regulated mode, reduces the treatment time, improves working conditions, eliminates the need for a time relay, is portable and its cost is low:
