    摘要： A physiological information monitoring system for monitoring physiological information on a patient is provided. A first monitor has a first display and a first connector. A second portable monitor has a second display, a second connector, and a signal input unit. A measurement signal of physiological information is input to the signal input unit. The second display unit displays information corresponding to the measurement signal. When the first connector and the second connector are connected, the second display is brought into a non-display status, whereupon the first display displays information corresponding to the measurement signal.

    摘要： A medical photometer includes a processor and a memory that stores an instruction readable by a computer. When the instruction is executed by the processor, the medical photometer acquires a first light attenuation of a first light beam that is transmitted through or reflected from a tissue of a living body, and that has a first wavelength, based on a first intensity signal corresponding to an intensity of the first light beam, acquires a second light attenuation of a second light beam that is transmitted through or reflected from the tissue, and that has a second wavelength, based on a second intensity signal corresponding to an intensity of the second light beam, and calculates a light absorber amount that is an amount of a first light absorber in the tissue, based on a ratio of the first light attenuation and the second light attenuation.
