Title:
NON-CONTACT VITAL SIGN MONITORING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/206902
Kind Code:
A1
Abstract:
A non-contact vital sign monitoring system, mounted on a mattress, and comprising a non-contact vital sign signal acquisition and processing system. The non-contact vital sign signal acquisition and processing system comprises a BCG signal acquisition module, a human body pressure acquisition module and a control module. A piezoelectric ceramic chip array is arranged on the mattress as the BCG signal acquisition module, and an impedance pressure belt is arranged as the human body pressure acquisition module, such that in cooperation with an intelligent dynamic wave peak tracing algorithm, heart rate data, breathing data, body movement data, in/out of bed conditions and abnormal sound data of a user in the sleep process can be extracted, so that the sleep condition of a user can be comprehensively analyzed. The system runs in an intelligent ultra-micro power working control mode, and when the pressure data measured by the human body pressure acquisition module indicates that the user is not on the bed, the non-contact vital sign monitoring system turns off most power utilization elements, so that the energy consumption is greatly reduced.
