Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrocardiograph (called a bathtub electrocardiograph) capable of detecting and monitoring an electrocardiographic waveform in a bathtub.

[0002]

2. Description of the Related Art Conventionally, most electrocardiographs have electrodes attached to the chest, extremities, etc. to induce an electrocardiographic potential and derive an electrocardiogram.

[0003]

In the above-mentioned conventional electrocardiograph, the electrode mounting position is determined, and the electrode must be mounted on the body, and it is extremely difficult for the user to mount it on the chest or limbs. There was a problem of being bothersome and difficult. In addition, the load electrocardiogram that monitors the electrocardiogram during exercise load is one in which the subject wears a portable electrocardiograph and is monitored during exercise, but the wearing state of the electrodes changes due to body movement during exercise. However, there is a problem that it is difficult to monitor accurately.

The present invention has been made in view of the above-mentioned problems, and it is possible to monitor an electrocardiogram in a bathtub so that the user does not have to worry about wearing the electrocardiogram and the electrocardiogram is accurately monitored during exercise load. The purpose is to provide a bathtub electrocardiograph to obtain.

[0005]

A bathtub electrocardiograph according to the present invention is provided with an electrocardiogram electrode installed in a bathtub and an electrocardiogram electrode connected to the electrocardiogram waveform from the electrocardiogram electrode for display on a display unit. It is composed of a main body for displaying. In this bathtub electrocardiograph, the electrocardiogram electrode is installed in the bathtub, and the subject only has to enter the bathtub, so that the annoyance of the electrode device is released. Further, since it can be said that an exercise load is being applied while taking a bath, it is possible to accurately monitor an electrocardiogram, such as a heartbeat or an electrocardiographic waveform, when the exercise load is applied, without attaching electrodes to the body.

The present invention will be described in more detail with reference to the following examples. FIG. 1 is a diagram showing a schematic configuration of a bathtub electrocardiograph according to an embodiment of the present invention. The bathtub electrocardiograph of this embodiment includes an electrode section 1 and a main body section (operation display section) 2 connected to the electrode section 1 by a connection cord 3. The electrode unit 1 is composed of a pair of related electrodes 1 a and 1 b and an indifferent electrode 1 c, both of which are installed on the inner wall surface of the bath 4. The main body 2 is installed on, for example, a bathroom wall, and on the surface thereof, a power switch 5, a transmission switch 6, an electrocardiogram monitor 7 and a heart rate display unit 8 are provided, and a circuit unit for waveform processing and signal processing is provided inside. Is built in. An enlarged view of the main body 2 is shown in FIG. 2, but the heart mark 9 is a display mark that blinks in synchronization with the heartbeat.

FIG. 3 is a circuit block diagram of the bathtub electrocardiograph according to the above embodiment. Inside the main body 2, an isolation amplifier 11 connected to the external electrodes 1a, 1b, 1c by a connection cord 3, a high-pass filter 12, a main amplifier 13, a low-pass filter 14, and A / D conversion. Circuit comprising a device 15, a CPU 16 for data processing the electrocardiographic waveform converted into a digital signal by the A / D converter 15, and a communication controller 18 for transmitting the obtained result data to an external storage output device 19. It has

When performing measurement using this bathtub electrocardiograph, the bathtub 4 is filled with hot water in the state shown in FIG. 1, the subject enters the bathtub 4, and the power switch 5 is turned on. .. As a result, the electrodes 1a, 1b, 1c pass through the body of the subject, a current according to the electrocardiographic waveform flows, the electrocardiographic waveform is captured by the CPU 16, and the electrocardiographic waveform is displayed on the display 17. The heart rate is displayed on the monitor 7 and the heart rate is calculated by the CPU 16 and displayed on the heart rate display 8 of the display 19. During the measurement, the heart mark 9 blinks in synchronization with the heart rate.
If the transmission switch 6 is turned on during the measurement or after the measurement, the measurement result is transmitted from the communication control unit 18 to the external storage output device 19 outside the bathroom.

In the above embodiment, the electrodes 1a, 1b,
Although the case where 1c is fixedly installed in the bathtub 4 is shown, if it is fixedly installed and the distance between the electrode and the body increases due to the posture during bathing, the amplitude of the electrocardiogram becomes small and the electrocardiogram cannot be detected. There is also a risk of becoming. Even if the electrocardiogram can be detected, the electrode position at that time is not always optimal. In order to avoid such an inconvenience, the main body 2 is provided with means for outputting the amplitude value of the electrocardiographic waveform, for example, a buzzer (the circuit portion is connected to operate by the output of the CPU 16 in FIG. 3), While performing the measurement, the electrode position is moved, and the electrode is installed at the position where the buzzer sound is maximized.

In order to make the electrodes movable, it is sufficient to use detachable electrodes in the bath 4. 4 and 5 show the detachable electrode. 4 and 5 (a) are front views,
(B) is a side view. The electrode 1 of FIG. 4 is used when the bath 4 is a magnetic body, and the electrode 1 connected to the connection cord 3 is attached to the magnet 20. By adsorbing the magnet 20 on the wall surface of the bathtub 4, the electrode 1 can be freely installed. Of course, it can be easily removed by hand.

In the electrode 1 of FIG. 5, a handle 22 having a hook portion 21a is attached to the electrode base 21 and the electrode 1 is fixed to the electrode base 21. This electrode has a hook 2
The electrode 1 is positioned by hooking 2a on the upper end of the bath 4, but the electrode 1 can be freely moved by laterally shifting the hook portion 22a.

[0012]

According to the present invention, an electrocardiogram electrode installed in a bath and an electrocardiogram electrode are connected to the electrocardiogram electrode to process the electrocardiographic waveform from the electrocardiogram electrode and display it on the display unit. Therefore, the subject can perform the measurement as long as he / she enters the bathtub, and the annoyance of mounting the electrode on the body is released, and the subject can easily monitor daily. In addition, entering the bathtub and soaking in hot water is equivalent to exercising, and there is no risk of the electrodes coming off due to exercise.
It is possible to measure electrocardiogram during exercise load. It is also possible to detect an abnormal change in heart rate during bathing and notify the user or a person other than the user by an alarm.
