DEVICE FOR CORRECTION OF SLEEP CHARACTERISTICS Russian patent published in 2015 - IPC A61B5/53 A61N1/365 A61M21/00 

FIELD: medicine.

SUBSTANCE: device for correction of sleep characteristics contains sensor for registration of electrodermal activity EDA, connected with unit of analysis and extraction of signals of skin-galvanic responses SGR, generator of stimulating electric pulses, on-skin electrodes and control unit. Device is made in form of monoblock with possibility of fastening on user's palm. Monoblocks case has front and back side, and fastening elements. Three electrodes, placed with possibility of galvanic connection with skin of user's hand palm, are located on back part. Measuring electrode is connected to input of sensor for EDA registration, with stimulating electrode being connected to output of generator of electric pulses, with the third one being common neutral electrode of galvanic circuits of said sensor and generator. Units of analysis and extraction of SGR signals and control unit are made on base of microprocessor with possibility of periodical control of current condition of galvanic contact of electrodes with skin, cyclic measuring of SGR intensity and supply of stimulating electric pulses in pauses between SGR measuring, and provide three modes of functionality: sleeping mode - in absence of galvanic contact of electrodes with skin; mode of EDA registration - in presence of galvanic contact of electrodes with skin, including extraction of SGR pulses and counting their quantity N for given time interval and comparison with threshold value; mode of stimulation - if quantity N of SGR pulses exceeds threshold value, including periodical supply of electric pulses to stimulating electrodes during specified time interval.

EFFECT: invention application makes it possible to extend arsenal of technical means for correction of patient's physical condition during sleep and further wakefulness, increase index of slow-wave sleep stage, power of delta-waves and therefore deepen sleep sensation, phases of fast eye motions, and increase sleep quality in general.
