Description

This invention relates to medicine, namely to implantable pacemakers.

The purpose of the presentation is to determine the energy supply of the power source.

The drawing is a diagram of a pacemaker.

The device contains a power source, a control unit 2, a generator of 3 C pvly-lyping pulses, a reed switch 4, a counter 5 to a controlled stabilizer 6, voltage p1; .

The device operates as follows.

Impulses from general-ora 3 stimulating impulses; Ive the patient's heart and cause electrical irritation. The control unit 2, through the controlled voltage stabilizer 6, measures the energy of the power supply source 1, the control signals from which are fed to the first input of the generator 3 stimulating pulses. Under these control signals in the generator 3 of the stimulating pulses, the frequency is reduced and an increase in the duration of the stimulation pulses, the change of which serves to continuously control the state of the power source. In addition, an increase in the pulse duration by the end of the cpiSrta service of the power source 1 is also used to maintain the energies of each stimulating pulse at approximately a constant, given level 5, regardless of the change in the power source.

When the magnet is brought up to the place of implantation of the pacemaker, the reed switch 4 is activated, the input of the counter 5 is connected to the output of the stimulating generator 3, which starts counting 2-32 pulses of the stimulating generator 3. According to the signals from the output account- | Chip 5, the controlled voltage stabilizer 6, increases its internal resistance by 1–5 kΩ (depending on the type of power source used, corresponding to a depletion of the power source 1 by 0.2–1.0 g. Thus, after each stimulation pulse The simulated power supply source 1 is simulated. The control unit 2 analyzes the remaining energy and changes the characteristics of the stimulating pulses generator 3. With the help of external electrocardiographic devices, the pulse parameters are monitored in stimulation by the nature and their variations determined remaining capacity of the power source and I during normal operation prior to the pacing of the torus Unimplantation operation.

When the magnet is removed from the implantation site, the electrocardiostimulus of the torus 4 switches off. After some time, the counter 5 and the controlled voltage stabilizer 6 are set to the initial (the initial state, which was before the operation of checking the energy of the power source I of the power supply, and the whole apparatus works as described.
