2. Description of the Related Art An electrocardiograph is a device for measuring the action potential of the heart in a hospital or the like. In order to accurately measure an electrocardiogram using this electrocardiograph and make a highly accurate diagnosis, it is necessary to accurately attach a plurality of electrodes to a predetermined part of the body. Usually 4 on limbs and 6 on chest, total 1
It is necessary to attach zero electrodes, and considerable experience is required to quickly attach these electrodes. By the way, in recent years, unlike such an electrocardiograph, a simple electrocardiograph for measuring as a simple guide has been known. For example, in the simple electrocardiograph described in Japanese Patent Laid-Open No. 61-41438, when an abnormality is felt in the heart, an electrode is pressed against the chest for measurement. In order to perform measurements using such a simple electrocardiograph, it is necessary to remove the buttons on the clothes or tuck up the clothes to directly contact the electrodes with the skin of the chest, making it difficult to use in public. There is. Always carry such a simple electrocardiograph with the person who recognizes that there is an abnormality in the electrocardiogram from time to time, and if you do not know that there is an abnormality in the heart, carry such a device with you. I don't have it, and I don't keep it at home. The initial symptoms of heart disease often include stomach discomfort and chest pain. For example, even if you feel sick while eating, if you stay still for a while, these symptoms may disappear and you may forget about it. Also, if you are going to see a doctor, you can't move when your symptoms are strong, and you'll be able to go after your symptoms have eased.
Doctors often cannot make a clear diagnosis. Other simple electrocardiographs include those described in Japanese Utility Model Publication No. 2-130608.

[0003]

As described above, the conventional simple electrocardiograph has a problem that electrodes cannot be easily attached in front of a person. In addition, a simple electrocardiograph will not be kept at home if no abnormalities in the heart are usually recognized. Therefore, when some kind of heart disease suddenly occurs, the electrocardiogram cannot be measured, making it difficult for the doctor to make a diagnosis.

The present invention has been proposed in order to solve such a conventional problem, and provides a telephone with an electrocardiogram measuring and transmitting function which can easily measure an electrocardiogram and can transmit the measured electrocardiogram to a telephone line. The purpose is to do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A specific embodiment of a telephone with an electrocardiogram measurement transmission function according to the present invention will be described in detail below with reference to the drawings. An embodiment of this telephone is shown in the perspective view of FIG. In this figure, a first electrode R is exposed and mounted on the right front part of the telephone body 4, and the right hand of the subject can come into contact with this electrode R. A second electrode L for guiding an electrocardiogram is exposed and attached to the lower part of the handgrip 2 in the handset 1 of the telephone, and when the handgrip 2 is held by the left hand, the subject L touches the electrode L. Left hand touches. Also, the ear electrode 3 which is the speaker portion of the handset 1 is provided with the third electrode N exposed and mounted on the convex portion on the outer peripheral side that can be easily contacted when the ear is pressed against the handset 1. As shown in FIG. 2, when talking with the receiver 1, the electrode N contacts the ear of the subject.

These electrodes R, L and N are connected to the input terminals of the electrocardiogram amplifier 5 as shown in FIG. 3, and the electrocardiogram of the subject is derived by this amplifier 5. The measured electrocardiogram signal is digitally converted and then taken into a CPU (Central Processing Unit) 6. CP
The electrocardiogram data taken in U6 is sent to the modem 7 built in the telephone body 4. The output terminal of the modem 7 is a bipolar switch 8 which is switched by the CPU 6.
Connected to the switched terminals 9a and 9b. On the other hand, the handset circuit 11 to which the handset 1 is connected is connected to the switched terminals 10a and 10b of the bipolar switch 8, and the movable terminal side of the bipolar switch 8 is connected to the public telephone line 12. Normally, this bipolar switch 8 has terminals 10a, 10 to be switched.
It is switched to the b side. In addition, a bipolar switch switching control signal is input to the CPU 6 from the transmission destination via the telephone line 12. In the power supply circuit 13 connected to the AC power supply, a stabilized DC power supply for supplying power to each circuit unit is created.

Next, the operation of the telephone having the electrocardiogram measurement / transmission function configured as described above will be described with reference to the flowchart of FIG. First, when a symptom associated with some kind of heart disease occurs, the subject himself / herself picks up the handset 1 and calls the doctor (steps S1 and S2). After the call with the doctor is secured, inform the doctor of the symptoms. At this time, the doctor determines whether or not it is necessary to examine the electrocardiogram of the subject, and if there is no need to examine it, gives an appropriate instruction and puts the receiver (steps S3 to S7).

When the doctor determines that it is necessary to examine the electrocardiogram, each electrode R,
In order to bring L and N into contact with each other, the receiver 1 is held by the left hand, the ear is firmly applied, and the electrode portion of the telephone body 4 is instructed to attach the right hand (steps S5 and S8).
