Abstract
A probe connected to a pulse photometer include: a first light-emitting portion having a first light-emitting surface from which first light having a first wavelength used for calculating a concentration of a first light-absorbing substance in blood of a patient is emitted; a second light-emitting portion having a second light-emitting surface from which second light having a second wavelength that is used for calculating the concentration of the first light-absorbing substance is emitted; and a third light-emitting portion having a third light-emitting surface from which third light having a third wavelength that is not used for calculating the concentration of the first light-absorbing substance is emitted. A distance between a first reference point of the first light-emitting portion and a second reference point of the second light-emitting portion is shorter than a distance between a third reference point of the third light-emitting portion and the first reference point.
