摘要： The sensor mounting time period informing apparatus is provided with the detecting part, the timer part, the discriminating part, and the informing part. The detecting part detects whether or not the sensor is mounted on the living body for measuring biological information. The timer part counts the elapsed time period during which the sensor is continuously mounted on the living body based on the detection results of the detecting part. The discriminating part discriminates whether or not the elapsed time has reached the specified standard time. The informing part issues a notification when the elapsed time has reached the standard time based on the discrimination result of the discriminating part.

摘要： An apparatus for measuring a concentration of a light-absorbing substance in blood is disclosed. A light emitter emits light beams to irradiate a living tissue, each of the light beams being associated with one wavelength which is absorbed by the blood. A first instrument measures first intensities of the light beams, which are to be incident on the living tissue. A second instrument measures second intensities of the light beams, which are transmitted through the living tissue. A first calculator calculates an attenuation variation ratio, which is a ratio of attenuation variations of the respective light beams due to variation of a volume of the blood caused by pulsation, based on the second intensities of the light beams. A second calculator calculates the concentration based on the first intensities, the second intensities, and the attenuation variation ratio.

摘要： A blood pressure measuring apparatus, which measures a blood pressure of a living body, includes: a cuff-pressure control unit which controls a cuff pressure of a cuff that presses a part of the living body; an oscillation signal detection unit which detects an oscillation signal from the cuff pressure; a blood pressure specification unit which specifies systolic and diastolic blood pressures as the blood pressure of the living body from the oscillation signal; and a blood pressure determination unit which determines whether systolic and diastolic blood pressures are appropriate or not. The cuff-pressure control unit controls the cuff pressure to be inflated to a first set value, the blood pressure specification unit specifies the systolic and diastolic blood pressures based on a change of an oscillation signal that is detected by the oscillation signal detection unit when the cuff pressure is inflated to the first set value, and when the blood pressure determination unit determines that both the systolic and diastolic blood pressures are appropriate, the cuff-pressure control unit ends the inflating of the cuff pressure to release the cuff pressure.

摘要： An apparatus for determining concentrations of hemoglobins additionally uses a light source 3 which emits light of a third wavelength in an orangy red wavelength region of 590 to 660 nm. The apparatus includes light receiving means 6 for receiving lights that are emitted by the light sources and transmitted through or reflected by a living tissue, attenuation ratio processing means 15 for processing attenuation ratios &PHgr; on the wavelengths based on variations of signals associated with the wavelengths output from the light receiving means, which variations are caused by a pulsation of blood, and concentration ratio processing means 16 for processing concentration ratios of at least oxyhemoglobin, deoxyhemoglobin and carboxyhemoglobin based on the output signals from the attenuation ratio processing means. The apparatus thus constructed can properly measure carboxyhemoglobin COHb, and present its concentration display and an alarm display in a simple manner, which is clinically effective.

摘要： In an apparatus for measuring an oxygen saturation in blood, a plurality of light emitters are adapted to irradiate a living tissue with a plurality of light beams having different wavelengths. A light receiver is adapted to receive the light beams reflected from or transmitted through the living tissue to generate pulse wave signals in accordance with pulsations of the blood in the living tissue. A separator is operable to separate each of the pulse wave signals into a plurality of amplitude signals each of which is associated with one frequency, thereby generating pairs of amplitude signals each of which is associated with one of a plurality of frequencies. A first processor is operable to calculate a ratio between the amplitude signals in each of the pairs of the amplitude signals. A selector is operable to select one of the pairs of the amplitude signals. A second processor is operable to calculate the oxygen saturation based on the ratio of the selected one of the pairs of the amplitude signals.
