Description

The wireless ECG device with attachable and wireless eletronic stethoscope for 24-hour monitoring in real time

The present invention arranges electrodes for measuring biopotential signals generated in the heart to be detachably attached to an attachment sheet or a band with elasticity, and a cable electrically connected to the electrode is attached to one side of an electrode strip for a wireless electrocardiogram (ECG) , Electrocardiogram), a wireless ECG device connected to a moderator is attached to the chest and then connected to an ECG analyzer and smart device (phone, wearable device) through wireless communication to monitor the measured records. In the course of the examination, it does not interfere with the cable as in the prior art, so it is easy to move, providing convenience to patients in daily life. A wireless ECG device equipped with an attachable wireless stethoscope that monitors breathing sounds, arterial sounds, intestinal noises, blood vessel sounds (hereinafter referred to as 'body sounds'), and body temperature in real time along with heart information for 24 hours. will be.

The electrocardiogram is recorded by measuring and recording the action current according to the contraction and expansion of the heart muscle by attaching an external electrode.

The action potential generated when the heart muscle contracts and relaxes causes an electric current that spreads from the heart to the whole body. This electric current generates a potential difference depending on the position of the body. can be detected and recorded.

Such an electrocardiogram is used to check the presence of abnormalities in the heart, and is used as a basic method for measuring diseases of the heart disease system such as angina pectoris, myocardial infarction, and arrhythmia, and is one of the medical devices occupying a very important position.

On the other hand, electrocardiogram measurement includes a vertical mode in which electrodes are connected to the left and right wrists and ankles of a patient to measure the electrocardiogram, and a horizontal mode in which electrodes are attached around the ribs to measure the electrocardiogram.

In the case of vertical mode measurement, electrodes are usually mounted on both wrists and left ankle, and in this case, 3 types of standard guidance and 3 types of unipolar guidance can be obtained.

The fourth electrode is placed on the right ankle and grounded to stabilize the ECG recording.

However, the electrode can be placed on any limb, and the electrode can be placed near the body of the extremity rather than the ankle or wrist. can

When measuring an electrocardiogram, that is, after the patient moves to the measuring room and lies on the bed, the examiner installs electrodes on both wrists, ankles, and chest, and the electrodes are connected to the electrocardiogram analyzer through a cable.

In order to measure the electrocardiogram using the wired method, electrodes are attached to the wrist and ankle, respectively, and 6 electrodes are attached to the chest. can

Also, when the electrodes are attached and the cable connected to the electrodes is connected to the electrocardiogram analyzer to analyze the electrocardiogram, the arm and leg get caught in the cable while the patient moves or toss and turns on the bed, and the electrode falls off the skin. In the process of measuring the ECG, a lot of time is required and the measurement process is cumbersome because there are many restrictions on movement.

In addition, during 24-hour Holter monitoring, the cable attached to the chest makes the patient's daily life inconvenient. If there is a cable for continuous monitoring, it may become difficult to continuously monitor the heart due to detachment during patient management or treatment.

On the other hand, the stethoscope generally listens to the heart sounds or breathing sounds, arterial sounds, intestinal noises, and blood vessel sounds (hereinafter referred to as 'body sounds'), which are generated in the patient's body, to determine whether the condition is normal. Electronic stethoscopes are widely used due to the recent development of electronic technology as an instrument used to confirm , the speaker converts the electroacoustic signal into sound and outputs it so that the doctor, etc. can hear the internal sound.

Therefore, in the process of measuring an electrocardiogram with an electrocardiogram device, a method that can measure body temperature and body sounds, including sounds of the heart, respiration, pleura, arteries, and veins generated in the body, and body temperature in real time 24 hours should be devised.
