Description

Technical Field

[0001] The present invention relates to the technical field of electrocardiogram acquisition, and more specifically, to an intelligent electrocardiogram acquisition bracket system and an application method thereof. Background Art

[0002] The positions of electrocardiogram leads are crucial for accurately evaluating cardiac electrical activity and usually include limb leads and chest leads; the limb leads include the right hand, left hand, right foot, and left foot. These electrodes are used to collect electrical activities at different positions on the upper and lower parts of the body, forming different lead combinations. The positions of the limb leads are the most basic electrode settings in the electrocardiogram, which can display the overall electrical activity of the heart; the chest leads include six electrodes, which are respectively placed at specific parts of the chest, and the positions are as follows: V1: the 4th intercostal space at the right sternal border, V2: the 4th intercostal space at the left sternal border, V3: the midpoint between V2 and V4, V4: the 5th intercostal space on the left midclavicular line, V5: the 5th intercostal space on the left anterior axillary line, and V6: the 5th intercostal space on the left midaxillary line; Currently, the conventional practice for electrocardiogram acquisition is to configure a large number of electrode patches. During acquisition, the electrode patches are attached to the corresponding positions on the human body one by one through a film. The accuracy of the attachment position of the electrode patches depends on the experience of the doctor. Moreover, if the electrode patches fall off during use, it will directly lead to acquisition errors; while some devices adopt an intelligent electrocardiogram acquisition system that completely relies on visual positioning. In the actual application process, it still requires too much manual intervention because when the fat at the skin surface of the rib reaches a certain thickness, it is very difficult to distinguish through vision, and thus recognition cannot be achieved; while some electrocardiogram acquisition devices that adopt the dot matrix pressing head method can finally achieve position calibration, but the number of positions of the points to be collected during the calibration process is relatively large, and the efficiency is very low. Therefore, an intelligent electrocardiogram acquisition bracket system and an application method that can better solve the above problems and enable self-service and efficient electrocardiogram acquisition are needed.
