At the same time, the signal of logical 1 from the output of the first circuit 8 And is fed to the input of the zero-setting of the ring counter 16, the signal of logical O is set on the first, second and third outputs. At the output of the pulse width generator 17, there is a logical O signal (high-frequency generator 3 is turned on) the logical O from the first and second outputs of the ring counter 16, respectively, arrive at the first and second control inputs of the amplifier 20, thereby prohibiting the formation of a stimulating signal at its output. The transmitting antenna 4 does not transmit a stimulating signal to the implantable device, i.e., the receiving antenna 5 and the input of the detector 6, the output 21 of which is connected to the diaphragm or phrenic nerves by means of electrodes. In the absence of a signal, the diaphragm or phrenic nerves are not stimulated (respiratory stimulation missing

The logical signal O from the third output of the ring counter 16 is supplied to the informational P input of the second D trigger 14, as a result of which the signaling means does not work. .

At respiratory frequencies f fnop.H or f f then. 6 (respiratory activity of the patient is impaired) at the output of the first circuit 8 And a logical O signal appears, which through the first input of the 10 OR circuit (at the same time, at the second input of the 10th pin is the logical O signal) is fed to the second input of the second circuit 9 And, thereby prohibiting the passage of a pulse to the clock inputs of the counters 11, 12. The logical O signal at the output of the first circuit 9 I is memorized, since each breath pulse confirms the logical O signal at the direct output of the first P, trigger 13 signal. output of the first circuit 8 and comes on in od zero setting ring counter 16 and

permits his work. At the outputs of the ring counter 16, alternately, starting with the first output, a logical 1 signal appears (only

one output, on the other two outputs, the signal of the logical O), and the time the output is in the state of logical 1 is determined by the frequency of the generator 1 and the division factor of the frequency divider 15. As soon as the signal of logical 1 appears at the first output of the ring counter 16, it arrives at the first control input of the amplifier

20 generates stimulating signals of the first energy mode at its output. The stimulating signals at the output of the amplifier 20 are radio pulses coming from

output high frequency generator.

Powerful with a gain Kp, Duration, frequency, and the law of variation of the low-frequency component of radio pulses (frequency modulation of video pulses) are formed in modulator 2, and radio frequency (which fills the video pulse) in high-frequency generator 3 ,. The radio pulses from the output of the modulator 2 are transmitted to the transmitting antenna 4 and transmitted by radio to the receiving antenna 5 in the patient’s body (receiving antenna 5

and detector 6 is transplanted into organ. nam patient). From the receiving antenna 5, the radio pulses arrive at the input of the detector 6, are converted into video pulses, which from the detector output b

through the electrodes enter the diaphragm of the 1-shea phrenic nerves, stimulate breathing with an initial stimulation mode corresponding to the first energy mode of the radio pulses

When a signal appears logical G (differential) at the second output of the ring counter 16 and the output of the imaging device 17 duration

the clock inputs of counters II, 12 (the signal of logical 1 through the circuit OR OR is fed to the second input of the second circuit 19 And,). Since the high-frequency generator 3 is turned off, there are no radio pulses at the input of the amplifier 20 and the patient’s stimulation with the electro-stimulator is not observed, i.e. the patient breathes on his own.

The passage of pulses from the output of master oscillator 1 through the second circuit 8 and to the clock inputs of counters 1.2 ensured; -t a measurement of the patient's own respiratory rate. The time duration of the logical 1 signal generated at the output of the pulse width former 7 is chosen such that it fits patiently’s breathing. If the frequency of breathing points (f) is within fnoc.H f- fnop.fe.s i.e. the patient's respiratory activity does not deviate from the norm, then at the output of the first circuit 8 a signal is generated. logical 1 and there is no stimulation, and the circuit goes to the initial state

When a logical 1 signal appears at the third output of the ring counter 16, a pulse 1 signal is generated at the output of the pulse width generator I 7, which switches on the high-frequency generator 3 and begins to control the patient's own breathing.
