Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a waterproof suction cup for a biological induction electrode used in electrocardiogram testing to determine the state of the heart during underwater exercise such as swimming rehabilitation.

``Prior Art'' Today, as a result of the development of medical technology and the improvement in the level of general heart examinations, not only serious heart diseases but also many mild heart diseases have been discovered and are contributing to the treatment of heart disease. However, children with mild heart disease, especially those with heart disease discovered through school heart examinations conducted nationwide, may be prohibited from swimming lessons, which is an extreme form of exercise.

Pediatric cardiology has so far determined that swimming is safe for children with mild heart disease.
This is because, in addition to the measurement results of the patient's electrocardiogram on the ground, the results were also considered from the aspect of energy consumption. Until now, there were no electrodes available for recording electrocardiograms while swimming, so the results of actual electrocardiogram testing while swimming were not available.

However, hemodynamics during swimming differs from exercise on land, and specific changes are observed during swimming, and the exact hemodynamics during swimming in school children are unknown. Gender cannot be confirmed. Using conventional tests, it has been difficult to permit swimming in children with mild heart disease, who are naturally considered to be able to swim.

Therefore, it has become necessary and urgent to actually record electrocardiograms while swimming to prove that swimming is safe for these school children.

In order to record electrocardiograms while swimming, biological induction electrodes are attached to the skin of the body while swimming, and the weak voltage induced on the skin of the human body is guided to an electrocardiogram installed on the ground. Therefore, there is a need to measure the amount of potential change occurring in the human body using an electrocardiograph.

The conventional method of recording an electrocardiogram by attaching this biological induction electrode to the skin surface of the body is shown in Figures 7 and 8.
Referring to FIG. 9, FIG. 7 is a perspective view of the biological induction electrode 14, which has a substantially circular adhesive piece 15. This adhesive piece 1
5 is a donut-shaped woven fabric having an opening 16 cut out in the center, and the lower side is sticky in order to adhere closely to the skin surface M of the living body, as shown in FIG. ing.

An electrode plate fitting part 17 made of hard synthetic resin is adhered to the upper surface of this adhesive piece 15 to close the opening 16. This electrode plate fitting part 1
A magnetic lead wire coupling portion 18 is provided protruding from the surface side of the wire 7 . As shown in FIG. 9, an electrode plate 19 is fixed to the lower surface of the lead wire coupling portion 18, which directly contacts the skin surface M of the living body and derives a weak voltage from the heart.

What is shown in FIG. 8 is a back view of the lead wire connection body 20, in which the weak voltage from the heart derived from the electrode plate 19 is transmitted to an electrocardiograph installed on the ground via the lead wire. It is meant to guide you. This lead wire connection body 20 is made of hard resin and has approximately the same size as the biological induction electrode 14, and has a recess formed inside, and a magnetic electrode coupling part 22 is fixed in the recess 21. One end of a lead wire 23 is connected to the coupling portion 22, and the other end of the lead wire 23 is connected to an electrocardiograph (not shown).

To record an electrocardiogram using the biological induction electrode 14 configured as described above, first, as shown in FIG. 9, the adhesive piece 15 of the biological induction electrode 14 is attached to the skin surface M of the biological body. , then the lead wire connection body 20
The magnetic electrode coupling part 22 is connected to the biological induction electrode 1.
The lead wire connecting body 20 is bonded to the magnetic lead wire connecting portion 18 of No. 4 and connected to the biological induction electrode 14, and the weak voltage from the heart derived from the electrode plate 19 is transferred to the heart via the lead wire 23. Record on an electric meter (not shown).

``Problems to be Solved by the Invention'' By the way, when an electrocardiogram is recorded while swimming underwater using such a conventional method, the lead wire connector 20 immediately connects to the biological induction electrode 14 due to extreme exercise such as swimming. The electrocardiogram cannot be recorded because it is out of alignment. In addition, water may cause the electrode plate 19 of the induction electrode 14 to
There were problems such as infiltration of the electrocardiogram, making it impossible to record an accurate electrocardiogram, and the in-vivo inductive electrode 14 also being peeled off from the skin surface M, making it impossible to record an adequate electrocardiogram.

"Means for Solving the Problems" Therefore, the present invention was made by focusing on the problems of the conventional art.

The above problems can be solved by providing a waterproof suction cup for biological guidance that prevents the biological guidance electrode from peeling off from the body even under water and can prevent water from entering the biological guidance electrode. The purpose is to solve the problem.

``Example'' Hereinafter, how the configuration of the present invention is actually embodied will be explained with reference to the drawings, together with its operation.

The tip of the waterproof panel 8 is inserted and penetrated from the convex side to the concave side. A magnetic electrode coupling part 10 is attached to the leading end of the lead wire 2 inserted into the through hole 9 of the waterproof disc 8, and is tightly attached to the concave side of the waterproof disc 8 so as to close the through hole.

The gap formed between the peripheral surface of the lead wire 2 and the convex surface of the waterproof panel 8 is sealed with an elastic sealing material 11 such as silicone rubber to prevent water from penetrating from the outer surface of the waterproof panel 8. is being prevented. Furthermore, an annular body surface contact sheet 12 is adhered to the concave surface of the waterproof panel 8 along a concentric circle surrounding the electrode coupling portion 10 with an adhesive 13, and an adhesive is also applied to the surface of the body surface contact sheet 12. is coated.

Next, the operation of the bioelectrode waterproof panel 5 having the above structure will be explained. First, as shown in FIG. 4, the adhesive piece 15 of the conventional biological induction electrode 14 is attached to the skin surface M

Furthermore, since the biological induction electrode 14 is covered with the waterproof suction cup 5, water does not enter the biological induction electrode 14. If the outer surface of the waterproof disc 8 of the waterproof suction cup 5 is further pressed, the body surface adhesion sheet 12 stuck on the concave surface of the waterproof disc 8 will come into close contact with the skin surface of the body, and the waterproof disc 8 will return to its original state. The suction force to return to the shape works, and it is possible to properly adhere to the skin surface of the body.

"Effects of the present invention" As explained above, according to the present invention, a magnetic electrode coupling portion is provided in a waterproof suction cup for a biological induction electrode,
Since the waterproof suction cup is fixed to the biological induction electrode, the waterproof suction cup is firmly fixed to the electrode, and there is no risk of it peeling off during swimming.

Furthermore, since the electrode plate that is in direct contact with the skin surface is completely covered by the waterproof suction cup, there is no risk of water entering the electrode plate.

Furthermore, since the electrode coupling part of the waterproof suction cup is formed of a magnet, the waterproof suction cup can be easily fixed to the electrode when in use, and can be easily separated when not in use, which is convenient.

In addition, since a body surface adhesive sheet is pasted on the concave surface of the bowl-shaped waterproof disc, the adhesion of the body surface adhesive sheet and the suction force to return the waterproof disc to its original shape combine to make it waterproof. Suction cups have the advantage of being in close contact with the skin surface of a living body.
