Wearable device for collecting surface electric potential based on distance segment weighting algorithm and method

Abstract

The invention discloses a wearable device for collecting surface electromotive force based on a distance segment weighting algorithm and a method. When a user wears the device, dry electrodes distributed on a vest collect the electric potential of the body surface of the user, which is connected to an analog front end and sent to a data collection system. The data acquisition system is connected with a PC terminal. Some of the signals received by dry electrodes are used as electrocardiogram signals to synthesize an electrocardiogram. If the corresponding leading signal is good, the leading signal is adopted directly. If the corresponding leading signal is not good, four different multi-lead algorithms are used to obtain the corresponding electrocardiogram. Based on the similarity, a distance segment weighting algorithm is used to select the one most capable of representing the electrocardiogram of the user from the four algorithms. Based on the resulting electrocardiogram, a patient'shealth can be analyzed and the location of the lesion can be determined according to the body surface potential mapping (BSPM) to guide the follow-up treatment.

Description

technical field [0001] The invention relates to a body surface potential acquisition technology, in particular to a wearable body surface potential acquisition device and method based on a distance segmentation weighting algorithm. Background technique [0002] With the improvement of people's living standards and changes in lifestyle, the incidence of cardiovascular disease is also increasing year by year, and its high disability rate, high rehospitalization rate and high mortality rate have caused a huge burden on the quality of life of patients and social development. At present, there are estimated to be 290 million patients with cardiovascular diseases in the country, and their case fatality rate is 2.5% to 3.0%, accounting for more than 40% of the death of Chinese residents. The high mortality rate, high disability rate, high medical risk and high medical burden of cardiovascular and cerebrovascular diseases make it a major social problem. The monitoring of various si...

Problems solved by technology

[0003] Although the invention with the application number CN201710262618.9 can monitor the patient's ECG in real time, the monitoring of the ECG is still not accurate enough and is greatly affected by the user's movement

It is impossible to perform further analysis and diagnosis on the patient, nor can it analyze the location of the user's heart disease

[0004] The invention with the application number CN201711309089.X monitors the health of the human body through the body's bowel sounds, heartbeat, breathing, body temperature, blood oxygen, etc., only the most basic monitoring is carried out, which is too general

For the increasingly common cardiovascular and cerebrovascular diseases, the effect of early detection and prevention cannot be achieved.
