Description

Technical Field

[0001] The utility model relates to the technical field of wearable devices, in particular to a wearable detection device for non-invasive continuous detection of human blood pressure under high pressure. Background Art

[0002] The existing common blood pressure measurement method is the cuff-type electronic blood pressure measurement method. However, the cuff-type electronic blood pressure measurement can only work under small-depth / shallow-depth conditions, and the measured value of the cuff-type electronic blood pressure is inaccurate under large-depth conditions. Based on this, in order to accurately and non-invasively obtain the true blood pressure value of the human body under large-depth conditions, it is necessary to first collect multiple physiological signals of the human body under high pressure, and then analyze the true blood pressure value of the human body under large-depth conditions based on the collected multiple physiological signals of the human body. In order to collect multiple physiological signals of the human body under high pressure, the present application designs a device for detecting multiple physiological signals of the human body for non-invasive continuous detection of human blood pressure under high pressure.

[0003] Moreover, at present, in a high-pressure environment, the components for detecting human electrocardiogram signals, the components for detecting human pulse wave signals, and the components for detecting blood pressure signals are mostly separately arranged. There is currently no integrated wearable structure that integrates the components for detecting human electrocardiogram signals, the components for detecting human pulse wave signals, and the components for detecting blood pressure signals. This integrated wearable structure can simultaneously detect the electrocardiogram signal, pulse wave signal, and blood pressure signal of the human body under high pressure.
