ELECTRONICALLY-CONTROLLED INHALER Russian patent published in 2010 - IPC A61M15/00 

FIELD: medicine.

SUBSTANCE: inhaler comprises a power supply, a generator with controlled output level, a control and display device, piezoelectric element connected to an output of the generator. In addition, it accommodates: an adapter with an AC supply decoupling, a start-stop device, an electronic switch, a thermal protection with response indication comprising a measuring bridge with a thermal resistor being in thermal contact with the piezoelectric element, a comparator and the circuit breaker. Thus feed circuits of the start-stop device are connected directly to the first and second outputs of the adapter, and all other devices are connected and disconnected from the second output of the adapter through the electronic switch with its input connected to an output of the start-stop device controlled with a clock button of the control and display device. An output of the variable direct voltage from the control and display device is connected to a frequency control input of the output voltage of the generator. Outputs of the reference and thermal-dependent voltages of the measuring bridge are connected to inputs of the comparator with its output connected to an inhibit input of the generator and to an enable input of the circuit breaker with its output connected to an output of the current source of the generator and to an input of the feed circuit of the indicator of the control and display device. The generator is designed to operate in the key mode and supplied with an output voltage frequency temperature compensator with its output connected to an input of a frequency regulator of the control and display device.

EFFECT: device provides higher operational safety.
