Abstract
Provided is a blood analysis device including a capillary tube, a photo sensor disposed on a sidewall of the capillary tube to detect blood flowing in the capillary tube, and an absorption sensor coupled to one end of the capillary tube to absorb the blood in the capillary tube.
Claims15
A blood analysis device comprising:
- a capillary tube;
- photo sensors disposed on a sidewall of the capillary tube to detect blood flowing in the capillary tube;
- and
- an absorption sensor coupled to one end of the capillary tube to absorb the blood in the capillary tube,
- wherein the absorption sensor contains a sensing material,
- the photo sensors include a first photo sensor and a second photo sensor, and
- each of the first photo sensor and the second photo sensor comprises a light emitting part emitting light having wavelengths different from each other.
