ELECTRIC STIMULATION DEVICE FOR TREATING GASTROINTESTINAL TRACT (VERSIONS) Russian patent published in 2007 - IPC A61N1/36 

FIELD: medical engineering.

SUBSTANCE: device has sealed capsule having two cup-shaped electrodes electrically insulated from each other. Hybrid integrated chip having pulse-stimulating oscillator is available in the capsule. The oscillator is connected to output device via frequency divider. The output device is connected to the cup-shaped electrodes and to electronic key. The chip is provided with power supply source, unit for measuring impedance having output connected to synchronization unit input via amplifier and restrictive resistor. Synchronization unit output is connected to pulse-stimulating oscillator input. The cup-shaped electrodes are identical to each other and connected with dielectric bushing bearing two identical additional electrodes connected in parallel and placed between the cup-shaped electrodes and electrically insulated from them and from each other. The additional electrodes are connected to the unit for measuring impedance and to unclosed input and output of the electronic key having input for permitting signal passage connected to the second frequency divider output. The second pulse-stimulating oscillator output is connected to the first cup-shaped electrode via the restrictive resistor. The power supply source is connected through its leads to the second electronic key, output device, synchronization unit, amplifier, unit for measuring impedance, frequency divider, the first electronic key. It is also connected to stimulating pulse oscillator via the second electronic key and to the second cup-shaped electrode. One of the cup-shaped electrodes has aspiration openings and nipple for making connection to catheter tube enclosing integrated hybrid chip according to another embodiment of the invention.

EFFECT: enhanced effectiveness of stimulation; high accuracy in measuring biological object impedance.
