OPTICAL FIBER CONTINUOUS DETECTING BLOOD SENSOR AND WEARING APPARATUS THEREOF

摘要

The application relates to the field of blood pressure detecting, provides an optical fiber continuous detecting blood sensor which includes sensing band. The sensing band includes an inner layer and an outer layer, and an accommodation space is formed between the inner layer and the outer layer. An optical fiber is provided in the accommodation space. One end of the sensing band is provided with a signal processor communicates with the optical fiber. The outer surface of the sensing band is covered by an elastic layer. The sensing band is flexible and can be curled into a ring. The optical fiber is arranged to extend along the sensing band so as to form a ring-shape sensing area. The outer surface of the sensing band is covered by an elastic layer, thereby the banding can be worn on the human wrist radial artery area securely. When detecting the blood pressure, even the sensing band rotates or dislocates because of the free movement of the people, the sensing area still can sense the pulse wave. There will not be any special positioning to wear the sensing band, and the 24 hours non-invasive continuous detection which is stable and precise for human blood detecting can be realized. The wearing apparatus is provided by the application includes an optical fiber continuous detecting blood sensor.
