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 improvements in general medical care regarding the heart, many cases of mild heart disease, as well as serious heart disease, have been discovered and are contributing to the treatment of heart disease. However, these mild cases of heart disease, especially heart disease discovered through school heart examinations conducted nationwide, may result in children being prohibited from swimming lessons, which are extreme exercises.

Until now, 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 aspect of energy consumption. That's why. Until now, there was no electrode device for recording electrocardiograms while swimming, and electrocardiograms had not actually been performed while swimming.

``Problem to be solved by the invention'' However, the circulatory dynamics during swimming differs from exercise on land, and specific changes are observed during swimming. Today, the safety of mild heart disease while swimming cannot be confirmed. Depending on the conventional examination, it has been difficult to accept swimming in patients with mild heart disease, who are considered to be eligible for swimming as a matter of course.

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 electrocardiograph installed on the ground. There is a need to measure the amount of voltage change occurring in the human body using an electrocardiograph.

Electrodes that are attached to the skin surface of the human body tend to peel off in water, so they are sometimes attached using adhesive, but it is troublesome to attach them to the skin surface, putting a burden on the subject, and it is difficult to attach them to the skin surface. Even when attached with adhesive, there are problems such as peeling off during strenuous swimming exercises, insufficient waterproofness, and failure to obtain good electrocardiogram records.

"Means for Solving the Problems" Therefore, the present invention was 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 A magnetic electrode coupling part 10 attached to the leading end of the lead wire 2
a bowl-shaped suction cup 5.6.7, an adhesive piece 15 having an opening 16 cut out in the center and capable of adhering to the skin on the lower side, and the upper surface of this adhesive piece 15 being adhered to and a hard electrode plate fitting disc 17 that closes the opening.
, a magnetic bowl-shaped suction cup coupling portion 18 provided on the upper surface side of the electrode plate fitting disc 17, and the skin of the living body located within the opening 16 on the lower surface side of the electrode plate fitting disc 17. The living body induction electrode 14 is equipped with an electrode plate 19 for deriving a weak voltage from the surface, and the adhesive piece 15 of the living body induction electrode 14 is pressed onto the skin surface of the living body to connect the bowl-shaped suction cup. Means called a waterproof electrode device for electrocardiogram recording, in which the electrode coupling part 10 of the bowl-shaped suction cup 5.6.7 is fixed to the part 18, and the weak voltage induced from the heart during underwater exercise is measured. It is an object of the present invention to solve the above-mentioned problems by providing a waterproof electrode device for electrocardiogram recording that is difficult to peel off from the body even in water and is easy to attach.

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

FIG. 1 is a perspective view showing an example of a combination of a bowl-shaped suction cup and a lead wire according to an embodiment of the present invention. In the figure, 1 is a connector, and one end of the connector has three lead wires 2, 3. 4
is connected to the other end, and a transmitter 20 with an antenna 21 attached thereto is connected to the other end, as shown in FIG.

One end of these three lead wires 2.3.4 has a bowl-shaped suction cup 5.
6.7 is connected.

The structure of this bowl-shaped suction cup 5.6.7 will be explained according to FIG. is sufficiently waterproof.

A through hole 9 is bored in the center of the waterproof panel 8, and the tip of the lead wire 2 of the IJhe wire 2, 3, 4 is connected to the convex side of the waterproof panel 8. It is inserted and penetrated towards the side. A magnetic electrode coupling part 10 is inserted into the through hole 9 of this waterproof panel 8, and the tip of the wire 2 has a magnetic electrode coupling part 10.
is attached to the concave side of the waterproof panel 8 so as to close the through hole 9.

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 comb, to prevent water from entering from the outer surface of the waterproof panel 8. is being prevented.

Further, on the concave surface of the waterproof panel 8, the electrode coupling portion 10 is provided.
An annular body surface adhesion sheet 12 is adhered with an adhesive 13 along a concentric circle surrounding the body surface adhesion sheet 12, and the surface of the body surface adhesion sheet 12 is also coated with adhesive.

FIGS. 3, 4, and 5 are a perspective view, a top view, and a back view of a living body induction electrode that is in close contact with the skin of a living body and derives the weak voltage of the heart from the skin. To explain the structure of the living body induction electrode, this living body induction electrode 14 has a substantially circular adhesive piece 15. As shown in FIG. 5, this adhesive piece 15 is a tortoise-shaped woven fabric with an opening 16 cut out in the center, and the lower side is in close contact with the skin surface of the living body. Because of this, it is sticky.

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. 3 from the surface of this electrode plate fitting part 17,
As shown in FIG. 4, a circular protruding piece 17a is provided, and a magnetic bowl-shaped suction cup coupling part 18 is fixed to the upper surface of the electrode plate fitting part 17 inside this protruding piece 17a. The magnetic electrode coupling portion 10 of the bowl-shaped suction cup 5 is detachably fixed to the bowl-shaped suction cup coupling portion 18 as shown in FIG.

Further, an electrode plate 19 is fixed to the lower surface side of the electrode plate fitting part 17, as shown in FIG. 5, which directly contacts the skin surface and derives a weak voltage from the heart.

Next, as shown in FIG. 7, the electrode plate coupling portion 10 of the bowl-shaped suction cup 5 is
When adhered to the bowl-shaped suction cup coupling portion 18 of the biological induction electrode 14, the bowl-shaped suction cup 5 is reliably fixed to the biological induction electrode 14,
Even during extreme exercise such as swimming underwater, it will not separate from the body. Further, since the biological induction electrode 14 is covered with the waterproof bowl-shaped suction cup 5, water does not enter into the biological induction electrode 14.

In this way, the weak voltage derived from the heart by the biological induction electrode 14 in close contact with the skin surface of the living body is transmitted to the antenna 21 of the transmitter 20 via the lead wire 2.3.4, as shown in FIG. The signal is transmitted from the ground, is received by a receiver installed on the ground, and recorded by an electrocardiograph.
