POWER SUPPLY AND CONTROL OF RADIATION SEMICONDUCTOR ELEMENTS OF MEDICAL MASK WITH BACTERICIDAL AIR TREATMENT Russian patent published in 2017 - IPC A41D13/11 H02M3/02 

FIELD: medicine.

SUBSTANCE: device for power supply and control of light-emitting diodes of a medical mask with bactericidal treatment of air is proposed. The device contains an inductive power storage device, a key, a key control unit, a diode, a capacitor and a resistor. One of the resistor and key outputs is connected to the terminal for connection of the common output of the power supply. The other key output is connected to the common point of connection of the inductive power storage and the diode anode, the cathode of which is connected to one of the capacitor outputs. The other output of the capacitor is connected to the common output of the power supply, the free output of the inductive power storage unit being connected to the terminal for connection the positive output of the power supply. The first input of the key control unit is connected to the terminal for the common output of the power supply, and its second input is connected to the free terminal of the resistor. The key control unit output is connected to the control input of the key. The connection points of the diode and capacitor, as well as the resistor with the second input of the key control unit are connected to the output terminals of the device.

EFFECT: increased reliability of disinfection regime provision, reduced current consumed by the battery and increased duration of continuous mask operation.
