Description

Signal acquisition device, supporting structure and electrocardiosignal detection, diagnosis and application system

Technical Field

The utility model relates to the technical field of medical equipment, in particular to signal acquisition device, bearing structure and electrocardiosignal detect diagnosis, application system.

Background

Electrocardiography (ECG) is a graph that records from the surface of the body, using an electrocardiograph, the changes in electrical activity that occur during each cardiac cycle of the heart, and is used to characterize the electrical activity of the heart. Electrocardiograms formally used as basis for disease diagnosis generally require multi-lead synchronous electrocardiograms such as twelve-lead electrocardiograms. Electrodes may be placed at specific locations of the body to capture traces of the electrical activity of the heart. The electrocardiogram has high sensitivity to a plurality of diseases, particularly cardiovascular diseases, and generally changes of the electrocardiogram can be captured only by the onset of the diseases, so that the diagnosis of the diseases, particularly the cardiovascular diseases, can be assisted by the electrocardiogram. However, the diagnosis of the electrocardiogram depends on whether the related diseases occur or not, the electrocardiogram changes when the diseases occur, and symptoms of some diseases are passed when the patients go to hospital for examination, so that the abnormality of the electrocardiogram cannot be detected, which results in that the diagnosis of some important diseases is easily ignored or the early diagnosis opportunity is missed. Therefore, it is important to develop a twelve-lead electrocardiographic examination apparatus which can be easily operated and used by a general user for early detection and early treatment of cardiovascular diseases.

With the rise of smart medical treatment, some users capture their own electrocardiograms through wearable electrocardiogram capturing devices such as a belt type, a vest type and the like which can be worn at any time or for a long time. However, the existing internet-based electrocardiographic capturing devices are far from the point that all people are configured, or even though the existing internet-based electrocardiographic capturing devices are configured, the existing internet-based electrocardiographic capturing devices are not always carried around, and when a user suddenly feels untimely, the user often has difficulty in finding a professional electrocardiographic capturing device nearby and cannot timely acquire a twelve-lead or more-lead synchronous electrocardiographic which can be used as a basis for disease diagnosis.

Many times, users still need to go to a comprehensive or professional hospital for electrocardiographic examination, and due to the shortage of professional technicians, hospitals with large treatment volumes still have quite serious waiting in line at the peak treatment time. For electrocardiographic examination, the examination mode of the hospital at present is that generally, a doctor in a consulting room makes an electrocardiographic examination request for a user, then a patient goes to the electrocardiographic examination room of the hospital to acquire electrocardiographic signals, the electrocardiographic room issues an electrocardiographic examination report after the electrocardiographic signals are acquired, and then the patient returns to the consulting room to receive further treatment of the doctor, wherein the queuing for acquiring the electrocardiographic signals in the electrocardiographic room is unnecessary time consumption. The time consuming process sometimes even results in missing symptomatic periods of the heart disease.

In addition, some wearable electrocardiogram capture devices may not be suitable for repeated use by a large number of ambulatory users. For example, wearable electrocardiographic capture devices of the vest type are not only slightly cumbersome to wear, but it is difficult to provide the same device for different patients or users to use the device to ensure sufficient hygienic safety. Such devices are only suitable for use by private individuals on their own.

In addition, when the electrocardiogram detection device is used, whether the electrodes can be closely attached to the human body easily and whether the signals are obtained accurately also has great influence on the electrocardiogram diagnosis.

Therefore, it is necessary to provide a related device for electrocardiographic detection, which is convenient, simple to operate, accurate in positioning and wide in application range.
