Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a waterproof electrode device for electrocardiogram recording 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 of the level of general medical care related to the heart, many mild heart diseases, as well as endocardial 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 the nationwide school heart checkups, may be prohibited from swimming lessons, which is an extreme form of exercise.

In pediatric cardiology, the basis for determining that it is safe for children with mild heart disease to swim is based on the results of electrocardiograms of patients on the ground, as well as the results of consideration from the perspective of energy consumption. It is. Up until now, there has been no electrode device for recording electrocardiograms while swimming, and the results have not been obtained from actual electrocardiogram testing while swimming.

``Problems to be solved by the invention'' However, unlike exercise on land, specific changes are observed in the hemodynamics during swimming, and the exact hemodynamics during swimming in school children are unknown. Today, the safety of children with mild heart disease while swimming 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 electrodes are attached to the skin surface of the body while swimming, and the weak voltage induced on the skin surface of the human body is output to an electrocardiogram installed on the ground. There is a need to measure the amount of voltage change occurring in the human body using an electrocardiograph.

The electrodes that are attached to the skin of the human body are
It easily peels off underwater, so it is sometimes pasted using adhesive, but it is troublesome to attach it to the skin and puts a strain on the subject, and even if it is attached with adhesive, it cannot withstand intense swimming exercise. There were other problems, such as the adhesive peeling off easily, insufficient waterproofness, and the inability to obtain good electrocardiogram records.

"Means for Solving the Problems" Therefore, the present invention has been made by focusing on such problems in the conventional art. A through hole 9 is drilled in the through hole 9, a lead wire 2 is passed through the through hole 9 from the convex side of the waterproof panel 8 to the concave side, and the lead wire 2 is closely attached to the waterproof panel on the concave side of the waterproof panel 8, and The bowl-shaped suction cups 5, 6, 7 have a magnetic electrode coupling part 10 attached to the leading end of the lead wire 2, and an opening 16 is formed by cutting out the center part, and the lower surface side is the skin surface. a hard electrode plate fitting plate 17 that is adhered to the upper surface of the adhesive piece 15 to close the opening, and a magnetic plate provided on the upper surface side of the electrode plate fitting plate 17. For living bodies, which includes a bowl-shaped suction cup coupling portion 18 and an electrode plate 19 for deriving a weak voltage from the skin surface of the living body located within the opening 16 on the lower surface side of the electrode plate fitting disc 17.
