Physiological signal measurement module and method

Abstract

The invention relates to a physiological signal measurement module which comprises a physiological signal sensing unit, a posture sensing unit and a processing unit, wherein the physiological signal sensing unit is used for measuring electrocardio signals and pulse signals of a measured person; the posture sensing unit is used for sensing the position of the physiological signal measurement module and outputting a plurality of position signals; the processing unit receives electrocardio signals, pulse signals and position signals, and is used for generating altitude change parameters representing the altitude difference between the physiological signal measurement module and the reference position according to the position signals; and the processing unit can be also used for calculating the current pulse wave delay time according to the electrocardio signals and the pulse signals, compensating the current pulse wave delay time according to the altitude change parameters to obtain a compensated pulse wave delay time, and obtaining a blood pressure signal according to the compensated pulse wave delay time.

Description

technical field The invention relates to a physiological signal measurement module, in particular to a mobile blood pressure signal measurement module. Background technique With the aging of the society, the elderly population is gradually increasing, and the demand for medical equipment has also increased significantly, making the supply of medical resources in short supply and large hospitals are often overcrowded. Furthermore, the increase in life pressure has increased the risk of cardiovascular diseases in modern people, among which high blood pressure is the main factor causing stroke. Therefore, physiological signal self-measurement equipment has gradually become an important goal of the development of the medical industry. Through self-measurement of physiological signals, individuals can monitor their own physiological conditions at any time and reduce the waste of medical resources. Known blood pressure measuring devices utilize wristband airbag sensing technolo...

Problems solved by technology

However, this sensing technology cannot measure blood pressure continuously, and it takes a long time to inflate and deflate the airbag

In addition, wrist-worn blood pressure measurement equipment will cause measurement errors due to the height difference between the wrist and the heart
