Abstract: A rotary damper includes a dish-shaped housing having a depression surrounded by a cylindrical wall, a viscous fluid contained in the depression, a damping rotor accommodated in the viscous fluid, and a cap covering the dish-shaped housing with a shaft of the damping rotor projecting through a central hole thereof. The cylindrical wall is provided at the base of its external periphery with a sloped annular portion of downward increasing diameter. A lower edge portion of a circular wall of the cap is contacted with the slope of the sloped annular portion during welding of the cap to the dish-shaped housing.

Abstract: An apparatus for achieving a long-term organism signal measurement, for example, an ECG waveform measurement includes measuring means (1) and input means (2) for setting and inputting organism signal analysis data in the measuring means (1). By supplying via the input means (2) organism signal analysis data unique to an organism to be measured into the measuring means (1), there is conducted a learning operation of the characteristics of the organism signals of the subject. Thereafter, the measurement and analysis of the organism signals are achieved for a long period of time by use of the measuring means (1). The measurement is accomplished after the characteristics of the organism signals of the subject are learned, and hence the reliability is increased. In addition, the realtime measurement and analysis are conducted by the measuring means (1) so as to store only abnormal waveforms, which facilitates the judgement thereof to be conducted by a doctor.

Abstract: A method and apparatus for measuring the temperature of a living body, providing a predetermined predictive functional formula in which the value of a shape parameter for reflecting the shape of a sensed temperature curve and the value of coefficient parameters for superimposing said prediction function on said sensed temperature curve are unknown. The temperature of a living body is sensed to obtain temperature data for subsequent processing, and elapsed time from start of temperature measurement is measured to obtain elapsed time data. The value of shape parameter is set on the basis of prescribed temperature data, and the value of coefficient parameters are set by solving simultaneous equations composed of a plurality of said predictive functional formula which includes said set value of shape parameter, and in which temperature data at a plurality of different points in time serve as purposive variables and functions of time data at the plurality of points in time serve as explicative variables.

Abstract: An electronic clinical thermometer for predicting a sensed temperature that will prevail at a future time is equipped with a predetermined predictive functional formula in which values of predetermined coefficient parameters for superimposing the prediction function on a sensed temperature curve are undetermined. Temperature data indicative of sensed body temperature are stored in correlation with elapsed time from the start of measurement, and plural items of the temperature data are read out by a predetermined method as measurement proceeds. By performing regression analysis based on a plurality of the predictive functional formulae, or by solving simultaneous equations constituted by the plurality of predicitve functional formulae, in which the sensed temperature data that have been read serve as purposive variables and functions of time data related to the temperature data serve as explicative variables, the values of the coefficient parameters are set.

Abstract: Disclosed is a blood pressure measurement apparatus in which a waveform discrimination method is used in the recognition of Korotkoff sounds in the measurement of blood pressure by auscultation. In processing executed by the apparatus, the minimum point or maximum point (C3) of a signal waveform indicative of the sound or vibration produced by a blood vessel is detected, and a maximum value or minimum value point (C2) is detected within a predetermined time region (t.sub.1) the final instant of which is the point (C3). If a level difference between the point (C2) and the point (C3) is within a predetermined range, there is detected a minimum value or maximum value point (C1) within a predetermined time region (t.sub.2) the final instant of which is (C2). If a level difference between the point (C1) and the point (C2) is within a predetermined range, there is detected a maximum value or minimum value point (C4) within a predetermined time region (t.sub.3) the starting instant of which is the point (C3).

Abstract: A sphygmomanometer includes a pump for applying variable pressure to a blood vessel, a microphone for sensing oscillation which is produced from the blood vessel being pressurized by the pump, a pressure detecting section for sensing the pressure being applied to the blood vessel, and a Korotkoff sound recognizing section for recognizing Korotkoff sounds out of the oscillation detected by the microphone. When the recognizing section has recognized a Korotkoff sound, the instantaneous pressure on the blood vessel is detected by the pressure detecting section to measure blood pressure. Recognition of Korotkoff sounds by the recognizing section is inhibited until a predetermined period of time expires since the recognition of a Korotkoff sound, to prevent the tailing of a Korotkoff sound from being recognized erroneously.

Abstract: A sphygmomanometer measures blood pressure inclusive of systolic and diastolic blood pressure values, pulse rate and atmospheric temperature prevailing at the time of measurement. The sphygmomanometer includes a memory for storing plural sets of information relating to measured blood pressure together with time information relating to the times at which the measurements were taken, and a printer for generating a graph having a time axis and an axis for information relating to blood pressure. In a first output mode, the printer graphically records systolic and diastolic blood pressure values that prevailed at the time of measurement, connects these two values with a line segment and graphically records pulse rate and atmospheric temperature that prevailed at the time of measurement on the time axis together with the corresponding systolic and diastolic blood pressure values.

Abstract: A blood pressure measuring apparatus displays that pressurization of a pressure cuff affixed to a patient is inadquate when elapsed time from the start of cuff depressurization to the detection of an initial sound of blood flow through the patient's blood vessel is shorter than a time interval between adjacent blood flow sounds, which interval approximately coincides with the patient's pulse interval.

Abstract: A method and apparatus for measuring the circulatory function of a living body in which a systolic blood pressure value is measured based on recognition of an initial Korotkoff sound made at the start of a reduction in pressure of a pressurized cuff affixed to a patient's arm. After the recognition of the initial Korotkoff sound, conditions are relaxed to enable measurement of pulse rate, judgment of the correctness of the systolic blood pressure value and a dicision as to whether applied pressure is adequate, all on the basis of sounds from the patient's blood vessel. Finally, diastolic blood pressure is measured based again on recognition of the Korotkoff sound.
