Description

Hand-held type electrocardio data acquisition card

Technical Field

The utility model relates to a hand-held type electrocardio detection device especially relates to a light and handy, use convenient hand-held type electrocardio data acquisition card of volume.

Background

Electrocardiosignals of a human body are vital sign signals which can be used for representing the heart health degree, and the monitoring electrocardiosignals can be used for judging various abnormal symptoms related to cardiovascular diseases, including bradycardia, tachycardia, arrhythmia, atrial premature beat, ventricular premature beat, atrial fibrillation and other abnormalities, so that early screening or disease monitoring is carried out on symptoms such as cardiac hypertrophy, myocardial infarction, coronary insufficiency or stenocardia and the like caused by hypertension or heart valve diseases.

The most common electrocardiosignal monitoring device at present is standard 12-lead electrocardiogram monitor equipment which can quickly acquire accurate electrocardiosignal waveforms and automatically analyze and diagnose various symptoms of electrocardiosignal abnormality; however, such devices are generally bulky, fixed in place, and expensive, and are therefore used primarily in hospitals or other centralized medical services. Another type of electrocardiographic signal monitoring device is a dynamic electrocardiographic monitor, which is a smaller electrocardiographic detection device compared with a standard 12-lead electrocardiographic monitor, and can be distributed to related disease patients and taken home for use; the dynamic electrocardiogram monitor is mainly suitable for the requirement of 24-hour continuous electrocardiosignal monitoring of a patient, so the dynamic electrocardiogram monitor has smaller size in volume and is convenient for the patient to carry, but the wearing time is too long, the daily life of the patient is influenced, and the obvious discomfort is brought, so the device still has a space for optimizing and improving the portability.

Taking a standard 12-lead electrocardiographic monitor device as an example, the device collects 12 paths of electrocardiographic signals through 10 lead wires, so the device is named as a 12-lead electrocardiographic monitor. The 10 lead wires are labeled as "RA, LA, RL, LL, V1-V6", wherein 6 lead wires of V1-V6 are attached to the chest of the human body through electrode pads (or electrode suction balls), and 4 lead wires of RA, LA, RL, LL are respectively connected to four parts of the right hand, left hand, right leg, and left leg of the human body through electrode pads (or electrode clips), wherein the potential difference between the lead wires RA and LA is called as I lead. At present, in some occasions needing to acquire the electrocardiogram rapidly, all 12-lead electrocardiogram signals are not needed, and only one lead signal is needed to carry out monitoring and analysis on the electrocardiogram. The measurement parts of the I-lead electrocardiosignals are from the right hand and the left hand of a human body, so that equipment for separately collecting the I-lead electrocardiosignal data can be designed, and the electrocardiogram can be quickly collected and analyzed and diagnosed while the reliability and the effectiveness of the electrocardiogram waveform are ensured.
