    This invention relates to medicine, namely cardiac pacemakers. Pacemakers are known that contain a sealed metal housing, a chemical power source, and an electrode L. The disadvantage of these devices is their large size and weight. Pacemakers are known that contain a sealed metal housing and a chemical power source, an electronic circuit and a 2J electrode connected in series. A disadvantage of the known devices is the large size due to the presence of a gap between the power source and the electronic circuit. The purpose of the invention is to reduce the size of the cardiac pacemaker. To achieve this goal, a cardiac pacemaker containing a sealed metal housing and subsequently connected chemical power source, an electronic circuit and an electrode is provided with a seal installed in the housing to form an electrolyte container, and the electronic circuit is placed into a sealed chamber above the seal. Figures 1 and 2 show the structure of the cardiac pacemaker} in FIG. 3 — the structure of the sealed chamber in FIG. 4 is the connection of the sealed camera and the housing. Cardiac stimulator 1 includes a body 2 in the form of a flattened parallel pypid. It is made of a conductive material, namely, a metal that is compatible with body fluids, such as titanium, in the housing 2 is a power source consisting of the anode 3, cathode 4, solid electrolyte 5 and separator 6. To the anode 3 and cathode 4, output terminals 7 and 8 are connected, a seal 9, there is a gap 10 between the wall of the housing 2 and the seal 9. The seal 9 is made of plastic or silicon. The anode 3 is made of lithium, and the cathode 4 is made of manganese oxide, the electrolyte is solid. The stimulus is transported in a DRY atmosphere, i.e. at extremely low relative humidity, or in vacuum, in order to avoid water vapor destroying the surfaces of the anode 3 and cathode 4, and especially lithium, when it forms the anode 3. You are anode terminal 7 or cathode 8 connected to conductor 11, while the terminal is connected to the housing 2 which is intended to form a mass. A housing 12 is inserted into the housing 2 above the seal 9, containing an electronic circuit 13, which is intended to generate stimulating pulses. Sealed chamber 12 is made of Mej tally connected to the electrode 14 and, in addition to the power supply, terminal 15 for electrical connection with the conductor 11, i.e. with anode or cathode. The electrode 14 is connected to one side of the sealed chamber 12, terminal 15 is located on the opposite side. On the side to which the electrode 14 goes, there is an opening 16. In addition, the hermetic chamber 12 is mechanically connected to the housing body 17 (figure 1). Terminal 15 is then connected to conductor 11. Terminal 15 is electrically connected to the output (not shown) of the electronic circuit 13, the other output of which is connected to the housing 2, which forms a mass. Then, the sealed chamber 12 is inserted into the interior of the housing 2. The opening 16 is located opposite the gap 10. The rear of the housing 17 solders the edge to the edge of the housing. Thus, the other pole of the power supply is connected to the electronic circuit 13 by this soldering. The hole 16 is then plugged. If the electrolyte is solid, the gap 10 and the hole 16 can be eliminated and thus soldering to seal the hole 16 is avoided. If the electrolyte 5 is not inserted into the housing 2 before inserting the sealed chamber 12, the assembly is as follows in a way. The anode 3 and the cathode 4, as well as the separator 6 are inserted into the bottom of the housing. Place the output terminals 7 and 8 and the seal 9, a gap 10 is fixed for this embodiment. Then, a connection is made between the wire 11, terminal 15, one of the terminals 7 or 8, connecting body 2 to ground. The sealed chamber 12 is inserted into the housing 2 and soldered to the cap 17, rigidly connected with the sealed chamber 12, to the housing 2, Krishka 3 17 in this case has an opening 16 which is located opposite the gap 10. This opening is located in the side of the cover 17, mainly from the side, the opposite electrode 14. A further step is to fill the free volume remaining between the body 2 and the sealed chamber 12 with a liquid electrolyte 18 using a pipette 19 (Fig. 2). Then the hole 16 is sealed. In this embodiment, the electrolyte 18 fills the entire free space, which is not the case in the known stimuli. To facilitate filling, a tube 20 is passed through the lid 17 through the opening 16. This tube is sealed at the end of the manufacture of the stimulator. The lid 17 of the stimulator and the hermetic chamber 12 are connected as follows (Fig. 3 and 4). Place the key 17 on one of the. the sides of the box 21. Its side 22 of the largest surface contains an opening 23 located in one of the extreme side portions. The jar of the stimulator has a hole 24, coaxial with the hole 23. In the counter part of the false part, 17 contains a hole 16 through which a liquid electrolyte can be further introduced. The collet is placed on the side 22 of the box 21. Then a cylindrical part 25, drilled along the axis of rotation XX., Is inserted inside the holes 23 and 24, inside of which a circular plate 26 is drilled in the center through which the conductor 27 passes, connected to the electrode 14. Plate 26 is made of an insulating material, such as a ceramic, such as sintered alumina. Then, the cylindrical part 25 is soldered to the side 22 of the box 21 and the lid 17. Thereafter, the electronic circuit 13 is inserted into the open box 21 and connected. with an electrode 14 and a terminal 15 located in the opening 28 29 of the hermetic chamber 12. Close the cap 29, which forms the bottom of the sealed chamber 12. Terminal 15 is connected to one of the poles of the power supply. Since the power source occupies the entire volume of the cardiac stimulator without gaps, the dimensions of the proposed cardiac stimulator are less known.
