Blood component analyzing method and blood component analyzing apparatus

摘要

A blood component is accurately analyzed by appropriately extracting a blood-vessel transmitted light component. In a blood component analyzing apparatus, a sensor section has a light-emitting section that irradiates light from a predetermined irradiation position situated over a blood vessel and a light-receiving section including a first photodetector that receives light at a first light-receiving position that is different from the irradiation position and is situated over the blood vessel and a second photodetector that receives light at a second light-receiving position that is not situated over the blood vessel. A spectrum synthesizing section synthesizes a first light-reception result at the first light-receiving position and a second light-reception result at the second light-receiving position by performing a predetermined synthesis process based on a positional relationship among the irradiation position, first light-receiving position, and second light-receiving position. A blood component analyzing section analyzes a blood component using the synthesis result.
