Pulse wave conduction parameter measurement system and method

A system, comprising:

• a first fiber-optic sensor, being configured to be placed in an area corresponding to the fourth thoracic vertebra of a supine subject to acquire first vibration information of the supine subject;
• a second fiber-optic sensor, being configured to be placed in an area corresponding to the fourth lumbar vertebra of the supine subject to acquire second vibration information of the supine subject;
• one or more processors;
• and
• one or more computer-readable storage medium having instructions stored thereon, which when being executed by the one or more processor, cause the one or more processors to perform steps of:
• acquiring the first vibration information of the supine subject from the first fiber-optic sensor;
• acquiring the second vibration information of the supine subject from the second fiber-optic sensor;
• generating first hemodynamic related information on the basis of the first vibration information, and generating second hemodynamic related information on the basis of the second vibration information;
• determining an aortic valve opening time of the supine subject on the basis of the first hemodynamic related information, and determining a pulse wave arrival time of the supine subject on the basis of the second hemodynamic related information;
• and
• determining an aortic Pulse Wave Transit Time of the supine subject on basis of the aortic valve opening time and the pulse wave arrival time.

A device, comprising:

• a main body, used for a subject to lie down, comprising an upper cover and a lower cover, and having a back area and a waist area;
• a first fiber-optic sensor, being placed in the back area of the main body and used for acquiring first vibration information of the supine subject;
• and
• a second fiber-optic sensor group, comprising two or more fiber-optic sensors, being placed in the waist area of main body and used for acquiring second vibration information of the supine subject;
• wherein the upper cover and lower cover together enclose the first fiber-optic sensor and the second fiber-optic sensor group therein.
