DETAILED DESCRIPTION OF THE INVENTION [I] Field of Industrial Application The present invention relates to a living body induction electrode, and more particularly to a living body induction electrode used when an electrocardiogram is derived in close contact with a living skin surface of a patient.

[II] Conventional Technology A conventional living body induction electrode is, for example, a clip type.

As shown in FIG. 5 (A), this clip type is designed to open the connection between the electrode element 3 of the base material 2 adhered to the skin surface 1 of the living body and the lead wire 10 connected to the electrocardiograph (not shown). Part 9, 6
It is performed by the clamping action of.

That is, a plastic container 4 is attached to the tip of the lead wire 200, and an opening 9 is formed in a fixed plate 8 on the back surface of the container 4.

Inside the container 4, a movable plate 7 is attached so as to face the fixed plate 8 so as to be movable in the direction of arrow a, and an opening 6 is formed in the movable plate 7.

When the knob 5 of the container 4 is pushed, the movable plate 7 moves against the force of the built-in spring, and the opening 6 thereof overlaps the opening 9 of the fixed plate 8.

In this state, the container 4 is inserted so that the spherical electrode element 3 protruding upward from the base material 2 is inserted into the overlapping openings 9 and 6.
Cover and release knob 5.

When the knob 5 is released, the movable plate 7 tries to return to the original position by the restoring force of the spring, so that the electrode element 3 is sandwiched between the openings 9 and 6.

Since the movable plate 7 is electrically connected to the lead wire 10, the electrocardiogram induced from the electrode element 3 is
It is input to an electrocardiograph (not shown) via the and is measured.

Push the knob 5 again and overlap the openings 9 and 6,
Since the electrode element 3 is not clamped and is free, the container 4 can be removed from the base material 2.

In addition, the conventional living body induction electrode is of a magnet type.

In this magnet type, as shown in FIG. 5 (B), the electrode element 12 of the base material 13 adhered to the skin surface 11 of the living body and the lead wire 17 are coupled by a magnetic action.

That is, the case 16 having the electrode element 15 is attached to the tip of the lead wire 17, and the height of the electrode element 15 is smaller than the height of the recess 17.

On the other hand, a cylindrical portion 12 projects upward from the base material 13 that is in close contact with the living skin surface 11, and inside the cylindrical portion 12,
The electrode element 14 is exposed.

The two electrode elements 14 and 15 form a pair of magnetic pole pieces.

By inserting the electrode element 15 of the case 16 into the recess 18 of the cylindrical portion 12 of the base material 13, the case 16 is attached to the base material 1.
When the electrode element 15 is covered from above, the electrode element 15 is firmly bonded to the other electrode element 14 by the magnetic action.

Since the cylindrical portion 12 is completely hidden in the recess 17 of the case 16 and the electrode element 15 is electrically connected to the lead wire 17, like the clip type (FIG. 5 (A)), Electrocardiogram can be measured.

If the case 16 is lifted upward by manually pressing the part of the base material 13, it can be removed against the magnetic action.

[III] Problems to be Solved by the Invention Firstly, in the conventional living body induction electrode, there is a problem that it takes a lot of time to attach and detach the lead wire.

That is, in the clip type (FIG. 5 (A)), the lead wire 10
The container 4 must be held and the knob 5 must be operated to connect and disconnect the container 9
Must be stacked so that the electrode element 3 penetrates them.

In addition, the magnet type (FIG. 5 (B)) also uses the lead wire 17
When connecting the electrodes, the case 16 must be held by hand, and the electrode element 15 must be inserted after being aligned with the recess 18 of the cylindrical portion 12. Conversely, when the lead wire 17 is removed, the base material 13 After pressing with a hand, the case 16 must be pulled with a strong force against the magnetic action.

Usually, when an electrocardiogram is taken, not only one living body induction electrode but also several living body induction electrodes are brought into close contact with the patient's chest.

However, it is apparent that performing the above-mentioned work for each living body induction electrode generally requires a lot of time for the lead wire attaching / detaching work.

Secondly, when the patient's back is fitted with a living body induction electrode for lying on a bed in order to obtain a so-called map electrocardiogram, the conventional technique has a problem that the patient feels pain.

That is, in the clip type (FIG. 5 (A)), the spherical electrode element 3 projects from the base material 2, and the volume of the container 4 is large and hard. In the magnet type (FIG. 5 (B)), Substrate 1
The cylindrical portion 14 accommodating the electrode element 14 protrudes from 3, and the case 16 connected to this also has a bulky and hard material.

If a large number of such living body induction electrodes are attached to the back of a patient and laid on the bed, the pressure from the bed causes a great pain in the back.

Next, thirdly, the conventional technique has a large weight,
There is a problem that it is inconvenient to carry.

That is, in the prior art (FIG. 5), the electrode elements 3 and 14 are
Both account for a large proportion of the whole, and are all made of metal.

Further, both the container 4 and the case 16 are bulky, and the corresponding metal electrode elements 7 and 15 are respectively incorporated therein.

Therefore, both of them are heavy as a whole, and when carrying a large number, it is inconvenient to carry them.

Further, fourthly, there has been a problem in the related art that in the case of pretreatment of the skin surface of a living body, a skin treatment cream or a paper file must be prepared in advance.

That is, before the biomedical induction electrode is brought into close contact with the skin surface, the conductivity of the skin surface portion must be improved.

Conventionally, therefore, a skin treatment cream or a paper file has been prepared separately for pretreatment.

The object of the present invention is to reduce the work time of attaching and detaching the lead wire, to feel pain even when wearing it on the back, to be lightweight, convenient for transportation, and to be able to pretreat the skin surface. To provide an induction electrode for use.

[IV] Means for Solving the Problem In the above problem, the opening 101 is formed in the insulating base material 100, and the first conductive magic tape 102 is attached so as to cover the opening 101. A second conductive magic tape 202, to which the electrolytic substance 103 is bonded and the lead wire 200 is connected, to the living body skin surface 300 side of the first conductive magic tape 102, is attached to the first conductive magic tape 102. This is solved by the biomedical inductive electrode, which is characterized in that it is detachable.

[V] Action As described above, according to the present invention, the opening 101 is formed in the insulating base material 100, and the first conductive magic tape 102 is attached so as to cover the opening 101, The second conductive magic tape 20 in which the electrolytic substance 103 is bonded to the living skin surface 300 side of the first conductive magic tape 102 and the lead wire 200 is connected
There is provided a biomedical induction electrode, wherein the second electrode is removable from the first conductive magic tape 102.

The first conductive velcro tape 102 and the second conductive velcro tape 202 are conductive velcro tapes used in daily life, and it is often easy to attach and detach them. Are known.

Therefore, the time required for the attachment / detachment work of the lead wire 200 is drastically shortened.

Further, since the first conductive magic tape 102 and the second conductive magic tape 202 are used as electrode elements, they are extremely thin and soft as a whole as compared with the conventional technique (FIG. 5).

Therefore, even if the patient's back was fitted with the biomedical induction electrode to lie on the bed in order to take a map electrocardiogram, the patient hardly felt any pain.

Next, both conductive magic tapes 102 and 202 are very light in weight as compared with the conventional electrode element, and occupy most of the entire structure.

Therefore, it is extremely convenient to carry a large number of living body induction electrodes.

Furthermore, pretreatment can be performed by sliding the first conductive magic tape 102 or the second conductive magic tape 202 on the skin surface 300 of the living body.

Therefore, it is no longer necessary to separately prepare a skin treatment cream or a paper file and pretreat the corresponding skin surface as in the conventional case.
