SENSOR AND BIOLOGICAL SIGNAL MEASURING SYSTEM

摘要

A biological signal measuring system includes a sensor and a biological signal measuring apparatus configured to calculate a blood refill time of a living tissue of a subject. The sensor includes a pressure applying portion configured to apply pressure on the living tissue, a light emitter configured to emit light toward the living tissue, a light receiver configured to receive reflected light or transmitted light from the living tissue, a first light transmitting member made of a light transmitting material and having one side contacting the light emitter and the other side arranged to contact the subject, a second light transmitting member made of a light transmitting material and having one side contacting the light receiver and the other side arranged to contact the subject, and a light blocking member configured to block light between the light emitter and the light receiver.

1. A sensor configured to measure a blood refill time of a living tissue of a subject, the sensor comprising:
a pressure applying portion configured to apply pressure on the living tissue of the subject; a light emitter configured to emit light toward the living tissue of the subject; a light receiver configured to receive reflected light or transmitted light from the living tissue of the subject; a first light transmitting member made of a light transmitting material, the first light transmitting member having one end configured as a contact surface contacting the light emitter and another end forming a contact surface to contact the subject; a second light transmitting member made of a light transmitting material, the second light transmitting member having one end configured as a contact surface contacting the light receiver and another end forming the contact surface to contact the subject; and a light blocking member configured to block light between the light emitter and the light receiver.
