Description

[Detailed description of the invention] Industrial field of application This invention relates to a chest lead electrocardiogram electrode device for electrocardiogram recording.

2. Description of the Related Art In this type of conventional electrode device, for example, six electrodes are used at different positions on the chest. It is well known that these electrodes are vacuum-fixed to the chest by means of an inverted bowl-shaped suction electrode at the tip of each specified cord.

Problems that the invention aims to solve However, because this vacuum fixation has a strong suction force, people with sensitive skin, especially women, often leave suction marks not only temporarily but for a long time. Furthermore, if the electrocardiogram recording technician is inexperienced, the cords for each electrode tend to become tangled, and it often takes time to separate and set them. In order to improve these problems, an electrode device for chest lead electrocardiograms has been proposed in which the electrodes are arranged in a frame and placed on the chest, but it is heavy and has a complicated structure, so it has not been widely used. I haven't reached it yet.

Therefore, this invention solves the problems of the conventional device as described above, makes the whole device compact and lightweight, allows the distance between each electrode to be freely adjusted, and eliminates the need for entangled electrode cords. It is an object of the present invention to provide an electrode device that is easy to set up without any problems.

Means for Solving the Problems In order to achieve the above object, the electrode device 1 according to the present invention has a flexible rod-like body 2 with a movable rectangular or L-shaped plate body 3, as shown in FIG. A plurality of electrode mounting plates 10, 11, 12, 14, 1 are attached to the edge of the plate body 3 and the rod-shaped body 2, respectively.
5, 16 are mounted at predetermined intervals so that their positions can be adjusted, and these mounting plates 10, 11, 12, 14,
A thick sponge body 20 is fixed to the lower surfaces of the sponge bodies 15 and 16, and electrodes 22 are fixed to the lower surfaces of the sponge bodies. Line 25 is connected.

Function When using the device, place the plate 3 so that it is located approximately in the center of the chest of the subject who is lying on his/her back as shown in FIG. Since the plate 3 has a certain amount of weight, the attachment bodies 14, 15, 16 attached to the rod-shaped body 2 other than the plate 3 are positioned on the flank surface by the bending of the rod-shaped body 2. Now that the setup is complete, all you have to do is turn it on.

According to the above, it becomes possible to record an electrocardiogram using a plurality of electrodes 22 arranged at a predetermined inter-electrode distance around the chest of the subject.

Moreover, at this time, even if the bending of the rod-shaped body 2 does not match the body shape of the subject, the sponge body 2
Since all the electrodes 22 come into contact with the skin due to the cushioning action, there is no need to worry about missing an electrocardiogram.

Embodiment FIG. 1 is a plan view of one embodiment, FIG. 2 is a side sectional view taken along line A-A in FIG. 1, and FIG. 3 is a B--
It is a side sectional view taken along line B, and FIG. 4 is an explanatory view of the operation showing an example of its use.

In these drawings, reference numeral 1 denotes an electrode device for chest lead electrocardiogram, and this electrode device 1 includes a hollow flexible tube 2 as a flexible rod-shaped body and an L-shaped tube movably attached to the flexible tube 2. A plate body 3 is provided. The plate body 3 consists of an upper plate 5 and a lower plate 6, and the flexible tube 2 is sandwiched between the ends of the plate body 3. For example, a screw 7 or a screw 8
It is designed so that it can be tightened and loosened, and can be rotated and moved relative to the flexible tube 2 depending on the degree of tightening.

A plurality of electrode mounting plates 10, 1 are provided on the edge parallel to the flexible tube 2 and the edge perpendicular to the flexible tube 2 of the plate body 3.
1 and 12 are, for example, U-shaped pieces 1 provided on the top thereof.
3 are fitted into the edges, and are arranged at predetermined intervals so that their positions can be adjusted.

On the other hand, on the flexible tube 2 adjacent to the plate body 3, a plurality of electrode mounting plates 14, 15, 16 are arranged at predetermined intervals so that their positions can be adjusted. Mounting plate 14,1
5 and 16 are the upper plate 17 and the lower plate 1 as shown in FIG.
8, with the flexible tube 2 sandwiched between the two plates,
For example, both ends are tightened with screws 19.
A thick cubic sponge body 20 is fixed to the lower plate 18 of the mounting plates 14, 15, 16 and the U-shaped piece 13 of the mounting plates 10, 11, 12. Electrode 22 is fixed. The sponge body 20 is made of a soft, cushiony, and highly porous material such as urethane foam or poval foam.

The electrode 22 is made of a metal mesh, such as a copper wire mesh or a thin plate, and a hydrophilic porous silicone gel layer 23 as a hygroscopic soft film is fixed to the lower surface of the electrode, which makes it easy to get stuffy. It's becoming like that. This lower layer does not necessarily have to be silicone gel, but from a hygienic standpoint silicone gel is most desirable.

Lead wires 25 are branched from the electrode cord bundle 26 disposed inside the flexible tube 2, extend through the flexible tube 2 or along the surface of the plate 3, and are connected to each mounting plate 10 to 12. and 14 to 16, which penetrate through the sponge body 20 and are connected to the electrode 22. In this embodiment, the lead wire 25 is provided inside the sponge body 20, but it may also be provided along the side surface of the sponge body 20. The electrode cord bundle 26 is taken out of the flexible tube 2 and connected to a required device.

With the above configuration, the plurality of electrodes 22 are attached to the mounting plate 1.
By adjusting the positions of the mounting plates 0 to 12 along the edge of the plate 3 and the mounting plates 14 to 16 along the flexible tube 2, the distance between the poles can be changed. .

Incidentally, the above-mentioned embodiment merely shows a preferable example, and the detailed design can be arbitrarily changed without changing the gist.

Effects of the device Since this device has the above-mentioned configuration, it can be set up simply by placing the plate on the chest of the subject who is lying on his/her back, and all the multiple electrodes can be connected by bending the flexible tube and using the cushion of the sponge body. Due to its action, it can be brought into contact with the skin of the examinee's chest. Therefore, no fixing means such as double-sided adhesive tape is required when setting. In addition, there is no need to suction the skin as in the past, and since it is lightweight, there is no pressure on the skin. Moreover, if the surface that comes into contact with the skin is made of silicone gel or the like, there is no need to worry about it affecting the skin even when used for a long time. Furthermore, when using chest leads in daily clinical practice, in addition to being able to record chest leads extremely easily, the overall structure is lightweight, the structure is simple, there is no tangle of electrode cords, and the cost is low. effective.
