る。 Electrocardiogram measurement methods include the standard limb lead method, in which the ends of the limbs are selected as two points that are almost equidistant from the heart, and the potential difference is measured, and one electrode (indifferent electrode) is placed at a point that is less affected by the electromotive force of the heart. On the other hand, there is a unipolar induction method that measures the potential difference between the other electrode (an electrode) placed on the chest wall near the heart.The latter method measures potential fluctuations in the myocardium relatively pure and selectively. It is advantageous in that it can be known in detail.

C 1 , the left sternal edge of the fourth intercostal space C 2 , the midpoint C 3 between the above C 2 and the next C 4 , the 5th intercostal space C 4 on the left midclavicular line, the same height as C 4 on the left anterior axillary line C 5 , and They are placed at six points on the left middle axillary line, C4 and C6 at the same height, and between these and the indifferent electrode T, lead V1 T- C1 , lead V2 T- C2 ...
...V 6 lead T-C 6 must be measured.
Because of the arrangement of the related electrodes at these 6 points, C 1 , C 2 ......C,
Conventionally, suction cups were attached to each of these locations to connect conductive wires, and these six conductive wires were connected to an electrocardiograph along with four conductive wires from both wrists and both ankles (indifferent electrodes). In this case, in order to connect the ends of the conductor wires (clips) attached to the suction cup and the part to be examined on the examinee, it is necessary to apply energizing jelly to each one, and be careful not to mix up the 10 conductors in total. Connecting it to an electric meter was also a troublesome operation.

れる。 The electrode body 7a is shaped like a closed cup and has a flat back surface and a hemispherical tip. The hollow part is a jelly storage chamber 7b, which is located at the tip opening 1.
5 and the jelly inlet 16 on the side.
The piston portion 6a of the pusher 6 described above is inserted into the jelly storage chamber 7b. This pusher 6 has a rod portion 17 inserted through a through hole in the electrode neck portion.
The upper end of the rod portion 17 protruding from the electrode neck portion 12 supports a push head 6b, and the lower end is connected to the piston portion. The main body of the piston part 6a is a jelly storage chamber 7
It consists of a disc (piston plate) that fits the inner diameter of the piston plate, and has a tip rod 18 protruding from the front surface thereof, which extends in the direction of the tip of the electrode, contrary to the rod part 17. The tip rod 18 has an outer diameter that fits into the tip opening 15 of the electrode body 7a, and has at least one (in this case two) jelly rods that are drilled from the tip surface and reach the circumferential surface at an appropriately retracted position. It has a seepage port 18a. A coil spring 19 surrounding the rod 17 is press-fitted between the push head 6b and the flange of the electrode neck 12, and the jelly injection port 16 of the electrode body 7a is closed with a suitable lid 20 after the energized jelly is injected into the jelly storage chamber 7b. It is sealed by.

However, when the pusher head 6b is pressed from this state, the piston plate 6a descends as the pusher 6 descends, so that the jelly in the storage chamber 7b is pressurized. The pressurized jelly passes through the jelly exuding port 18a in the tip rod 18 and oozes out from its tip opening, adheres to the body surface of the subject, and ensures electrical connection between this and the electrode element 7. This potential on the body surface is further increased by the electrode neck part 1.
The electrical power is transmitted from the conductive support plate 10 pressed against the electrically conductive support plate 2 to the outlet 22 (FIGS. 1 to 3) through the buried conductive wire 21 (FIG. 4) connected to the end thereof. In addition,
Jelly exudation port 18 in tip rod 18
When the circumferential opening of a is hidden within the tip opening 15 of the electrode, oozing of the jelly is blocked.
