SIGNALING DEVICE FOR DIAGNOSING HYPOGLYCEMIA STATE IN EARLY PERIOD Russian patent published in 2005 - IPC

FIELD: medical engineering.

SUBSTANCE: device has divider, comparison unit, oscillator, acoustic radiator, controllable current source, stable constant voltage source, perspiration equivalent unit, key member, illumination source, conductivity transducer having two electrodes, the first commutator, delay unit, trigger, inverter, discharge unit, the second commutator and feeding voltage availability indicator unit. The first delay unit inputs and the first commutator inputs are connected to comparison unit output. The first commutator input is connected to the first oscillator input which delay unit, trigger and inverter are connected in series. Inverter output is connected to the second input of the first and the second commutator. The first input of the second commutator is connected to the other conductivity transducer electrode and its output is connected to device body via resistor.

EFFECT: reduced current intensity passing through patient skin; excluded negative influence upon skin during prolonged operation time on patient arm during hypoglycemia attack; low power consumption.
