Problems solved by technology

However, the technologies disclosed in each of these documents use filters to remove myoelectric components generated by muscles other than the myocardium mixed in the measurement data. Unless noise can be completely removed, high-precision electrocardiographic data cannot be obtained.
Furthermore, it is virtually impossible to completely remove noise, and it is extremely difficult to accurately measure each characteristic wave (P wave, QRS wave, ST wave, etc.)

Embodiment 1

[0072] First, the overall configuration of the portable electrocomputer 100a of the present embodiment will be described.

[0073] Such as Figure 1 to Figure 6 As shown, the portable electrocomputer 100A of the present embodiment is slightly slightly reduced to the size and weight of the single-handed manner, so that the operability is excellent. The portable electrocomputer 100a includes a device body 110 and an external electrode unit 160a.

[0074] Next, the structure of the apparatus main body 110 will be described. The device main body 110 has a flat and elongated substantially rectangular shape shape, the outer surface (front surface 111, the back surface 112, the upper surface 113, the lower surface 114, the right side 115, and the left side 116) are disposed on the display unit, the operation unit, Electrode, etc.

[0075] Such as figure 1 with figure 2 As shown, the measurement button 142 as an operation button for the assay start is provided in the longitudinal direct...

Embodiment 2

[0101] First, the overall structure of the portable electrocardiograph 100B of this embodiment will be described.

[0102] Such as Figure 12 to Figure 17 As shown, the portable electrocardiograph 100B of this embodiment is the same as the portable electrocardiograph of the above-mentioned first embodiment. It needs to be small and light-weight up to the size and weight that can be held with one hand, and thus has excellent operability. The portable electrocardiograph 100B includes a device main body 110 and an external electrode unit 160D.

[0103] Next, the structure of the device main body 110 will be described. The device main body 110 has a flat and slender roughly rectangular parallelepiped shape, and its outer surface (front surface 111, back surface 112, top surface 113, bottom surface 114, right side surface 115, and left side surface 116) are provided with a display unit, an operation unit, Electrodes etc.

[0104] Such as Picture 12 with Figure 13 As shown, a display u...

Embodiment 3

[0132] The portable electrocardiograph 100C of this embodiment is the same as the portable electrocardiograph 100A of the above-mentioned embodiment 1. Figure 7 with Figure 8 The ECG waveform is measured in the measurement posture shown in. Therefore, for the same parts as the above-mentioned embodiment 1, the same reference numerals are attached in the figure, and the description thereof will not be repeated here.

[0133] Such as Figure 24 As shown, the portable electrocardiograph 100C of this embodiment includes a cord reel 158 as a winding device for winding the connection cable 181 of the external electrode unit 160A inside the device main body 110. The connecting cable 181 wound in the cord reel 158 is led out from the opening 116b provided on the left side 116 of the device body 110 to the outside of the device body 110, and its tip is electrically connected to the second electrode 122 provided on the external electrode unit 160A stand up. The cord reel 158 rotates in th...

Abstract

A portable electrocardiograph (100A), which has a first electrode (121) on the outer surface of a device body (110), and has an electrode leading out from the device body (110) to the outside of the device body (110) through a connecting cable (181). The second electrode (122). The first electrode (121) and the second electrode (122) are brought into contact with the surface of the body, and by measuring the potential difference generated between these electrodes, an electrocardiographic waveform is measured. As a result, myoelectric potentials generated by muscles other than the myocardium are not superimposed on the electrocardiographic waveform as noise, and the electrocardiographic waveform can be measured stably with high precision.

Description

Technical field [0001] The present invention relates to a portable electrocardrometer that can be carried and easily measuring and stores an electrocardiogram. Background technique [0002] In general, in order to diagnose angina or myocardial infarction, an electrocardiogram of patients is used. As an electrocardrometer for measuring the cardiometric waveform, a fixed electrocardiometer and a portable electrocardrometer are known. [0003] The fixed electrocardiometer is an electrocomputer provided in a hospital and other medical institutions, which is to load the electrodes to the body in a state where the patient is lying on the bed, and the instrument is measured. With such a fixed electrocardiometer, it is advantageous to measure the various cardiometric waveforms (eg, P-wave, QRS wave, ST wave, etc.) in precision measuring, but not necessarily The abnormality waveform is reproduced, sometimes it is sometimes necessary to accurately master the patient symptoms sometimes in t...
