Intelligent positioning method of blood pressure or hemodynamics detection sensor

Abstract

The invention provides an intelligent positioning method of a blood pressure or hemodynamics detection sensor. The intelligent positioning method comprises the following steps: wrapping the wrist of a person with a detector; starting a transverse driving device, driving the sensor to transversely move along the direction approximately perpendicular to the radial artery, and recording signal values sensed by the sensor at different positions in the process; according to the recorded signal values, the position with the strongest pulse pulsation is determined; the transverse driving device drives the sensor to move and stay above the position with the strongest pulse pulsation; starting a vertical driving device, driving the sensor to vertically move along the direction approximately vertical to the surface of the wrist skin, and recording signal values sensed by the sensor at different vertical positions in the process; according to the recorded signal value and the expected pressing state, the vertical position where the inductor should stay is determined; and the vertical driving device drives the sensor to move and stay at the vertical position where the sensor should stay. By means of the positioning method, the sensor can be accurately positioned, and blood pressure or hemodynamics detection is more accurate.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intelligent positioning method for a blood pressure or hemodynamic detection sensor. Background technique [0002] Common methods of blood pressure monitoring include auscultatory cuff blood pressure monitoring, electronic sphygmomanometer blood pressure monitoring and invasive arterial blood pressure monitoring. Auscultatory cuff blood pressure monitoring and electronic sphygmomanometer blood pressure monitoring cannot continuously monitor blood pressure changes and are accurate Although the invasive arterial blood pressure monitoring method can obtain continuous real-time monitoring of blood pressure and has high accuracy, it is to directly measure the arterial blood pressure by inserting the arterial catheter into the artery, and intervening in the human body may easily lead to subcutaneous hematoma and Infection, therefore, has obvious limitations in application. ...
