Apparatus and method for measuring blood component using light trans-reflectance
First Claim
1. An apparatus for measuring a blood component using light trans-reflectance, the apparatus comprising:
- an optical source unit to irradiate light to a test site of a test subject;
a transflective unit to transflect light transmitted through the test site among the light irradiated from the optical source unit;
a detection unit to detect the transflected light; and
an analysis unit to analyze the transflected light detected in the detection unit,wherein the test subject is a human body and the test site is an eyelid, andwherein the transflective unit is a contact lens configured to transflect light transmitted through the eyelid.

Abstract
An apparatus for measuring a blood component using the trans-reflectance of light irradiated to a transflective member disposed behind a test site. The apparatus includes an optical source unit irradiating light to the test site of a test subject; a transflective unit transflecting light transmitted through the test site; a detection unit detecting the transflected light; and an analysis unit analyzing the transflected light detected in the detection unit. A related method includes irradiating the light to the test site; transflecting light through the test site, detecting the transflected light, and analyzing the detected light. Blood component measurement can be easily performed without collecting blood by analyzing the transflected light with a high optical power containing much information about a blood component.

12. A method of measuring a blood component using light trans-reflectance, the method comprising:
-
irradiating light to a test site; transflecting light transmitted through the test site among the light irradiated to the test site; detecting the transflecting light; and analyzing the detected light by calculating a blood component level based on the transflected light, wherein the operation of irradiating the light to the test site includes irradiating light reacting with the blood component to an eyelid, and wherein the operation of transflecting the light transmitted through the test site includes transflecting light transmitted through the eyelid. - View Dependent Claims (13)
