Description

[Detailed description of the invention] [Field of industrial application] The present invention is an electrocardiograph transmitter used to record electrocardiograms to determine cardiac symptoms of living organisms engaged in underwater exercise such as swimming and rehabilitation. This relates to waterproof gear.

[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 cases of not only serious heart disease but also mild heart disease have been discovered and are contributing to the treatment of heart disease.

However, these mild cases of heart disease, especially children with heart disease found in school heart examinations conducted nationwide, are prohibited from swimming lessons, which is an extreme form of exercise.

Until now, pediatric cardiology has determined that it is safe for children with mild heart disease to swim, in addition to the results of the patient's electrocardiogram on the ground.
This is because the results were considered from the perspective of energy consumption.

[Problem that the invention attempts to solve]

However, the hemodynamics during swimming differs from the amount of 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. According to conventional tests, it has been difficult to allow children with mild heart disease to swim, although they are considered to be able to do so as a matter of course.

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

In order to record the electrocardiogram of a living body while swimming, electrodes are attached to the skin surface of the school child's body, and these electrodes are connected to an electrocardiograph installed on the ground with a cable. By swimming, the minute current from the heart induced on the skin surface during swimming is transmitted to an electrocardiograph installed on the ground via the cable, and the amount of potential change occurring in the living body is measured by the electrocardiograph. need to be measured.

By the way, when recording the electrocardiogram of a living body while swimming using an electrocardiograph installed on the ground, the cable must be lengthened accordingly when the living body swims a long distance, and making the cable that long will save money. In addition, making the cable long has the disadvantage that current leakage occurs before the minute current extracted from the heart reaches the electrocardiograph via the cable, making it impossible to obtain an accurate electrocardiogram.
In addition, when swimming vigorously underwater, the cables may become wrapped around the limbs, making it difficult to swim adequately.

Therefore, a method was devised to remotely record electrocardiographic signals of a living body moving underwater using perpendicular lines.

This method will be explained with reference to Figs. 3 and 4. In Fig. 3, 1, 2, and 3 are waterproof electrodes, and these waterproof electrodes 1, 2, and 3 are adhered to the skin surface of the living body.
One end of lead wires 4, 5, 6 is connected to the waterproof electrodes 1, 2, 3, respectively, and the other end is connected to a transmitter 7 that emits a wireless signal.

These waterproof electrodes 1, 2, 3 and lead wires 4, 5, 6
When a swimmer wears the transmitter 7 connected to the body via the transmitter strap 8 on the body surface of the swimmer and swims underwater, the electrocardiographic signals of the swimming body are transmitted to the waterproof electrode 1. , 2, 3, and the waterproof electrode 1,
The electrocardiogram signals detected in 2 and 3 are sent to lead wires 4, 5,
6 to a transmitter 7.

The electrocardiogram signal guided to the transmitter 7 is sent to the antenna 9
The transmitted electrocardiogram signal is transmitted to the transmitter 1 installed on the ground, as shown in Figure 4.
0 remotely by antenna 11. The received electrocardiogram signal is visualized on a cathode ray tube as shown in 12 or recorded on recording paper as shown in 13, and the electrocardiogram is analyzed.

If this method is adopted, no cables are used, which prevents current leakage and does not interfere with underwater exercise, but there is a problem in that water enters the transmitter 7 and an accurate electrocardiogram cannot be obtained. did.

Therefore, this invention was devised by focusing on the above-mentioned problems, and it consists of a plurality of waterproof electrodes that are attached to the surface of a living body to derive a weak current from within the living body, and a plurality of waterproof electrodes that are attached to the surface of a living body to derive a weak current from inside the living body. A plurality of lead wires each extending from the waterproof plug, a waterproof plug through which the plural lead wires pass through and a fitting groove is formed on the outer periphery of the waterproof plug, and a plurality of lead wires that pass through the waterproof plug. a transmitter connected to the connector, and a waterproof bag-like object, the transmitter connected to the connector is housed in the waterproof bag-like object, and the transmitter connected to the connector is housed in the waterproof bag-like object. The above problems are solved by providing a means for waterproofing a transmitter, which is characterized by fixing and sealing a bag-like object to a waterproof plug by fitting an elastic band into a fitting groove of the plug. The purpose is to

〔Example〕

Hereinafter, how the configuration of the present invention is actually implemented will be explained with reference to the drawings, along with its operation.

FIG. 1 is an exploded perspective view of the waterproof device of the transmitter of the present invention, in which numerals 14, 15, and 16 have waterproof properties for adhering to the skin surface of a living body and inducing a weak current in the living body. It is a waterproof electrode.

The waterproof electrodes 14, 15, 16 have lead wires 1
7, 18, and 19 are connected at one end, and the other end is connected by a connector 21 passing through an oval waterproof plug 20.

This elliptical waterproof plug 20 is made of synthetic rubber, and two fitting grooves 20a, 20a are cut in the outer periphery of the plug 20 in parallel vertically. This fitting groove 20

23 is a transmitter to which the other end of the connector 21 to which the lead wires 17, 18, and 19 are connected is connected.

The electrocardiographic signals induced from inside the living body by the waterproof electrodes 14, 15, 16 are transmitted to the lead wires 17, 1.
8 and 19 to a transmitter 23, and is transmitted from this transmitter 23.

Reference numeral 24 denotes a waterproof bag-like material made of rubber, and this bag-like material 24 has a size that allows the transmitter 23 to be accommodated therein with plenty of room.

A transmitter 23 connected to a connector 21 is housed in this bag-like object 24 as shown in FIG.
The inner peripheral wall 24a of the waterproof bag-like object 24 is brought into contact with the outer peripheral wall of the waterproof plug 20, and the waterproof bag-like object 24 is attached to the waterproof plug 2.
The ring-shaped rubber elastic band 2 is pushed into a fitting groove 20a carved in the outer circumferential wall of 0, and the ring-shaped rubber elastic band 2 is inserted from above the waterproof bag-like object 24 pushed into the fitting groove 20a.
