An electronic clinical thermometer comprises a circuit for measuring and displaying the temperature of a portion being measured, a secondary battery for supplying electric power to the circuit, rectifier means connected to the secondary battery, a power receiving coil connected to the rectifier means for inducing a voltage in response to a change in an external magnetic field applied to the power receiving coil, and a hollow bar-shaped casing housing the circuit, the secondary battery, the rectifier means, and the power receiving coil. The secondary battery can be charged efficiently through the power receiving coil in response to the change in the external magnetic field. An apparatus for charging the electronic clinical thermometer comprises container means having a cylindrical cavity for accommodating a plurality of electronic clinical thermometers, a power transmitting coil disposed around the cylindrical cavity, and a.c. supply means for supplying an alternating current to the power transmitting coil, whereby the secondary battery can be charged by exciting the power receiving coil through inductive coupling between the power transmitting and receiving coils with the power transmitting coil positioned closely to the power receiving coil in the electronic clinical thermometer that is accommodated in the cylindrical cavity.

Electronic clinical thermometer

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.

Method and apparatus for measuring circulatory function

An electronic clinical thermometer successively stores the temperature detected at a portion of a body, and measures the time which has elapsed since start of measurement. The thermometer repeats, periodically, a process of obtaining and displaying a predicted value of a stable temperature from the detected temperature and elapsed measurement time on the basis of a stable temperature prediction function in which measurement time is a variable, the temperature prediction function defining a temperature change up to a final, stable temperature. The prediction computation is halted when, after the elapsed measurement time has exceeded a prescribed magnitude and a difference exhibited by the detected temperature corresponding to two successive points in time no longer shows an increase outside a prescribed range, the detected temperature corresponding to a present point in time exhibits a decrease outside a prescribed range when compared with the detected temperature at the preceding point in time.

Electronic clinical thermometer, and method of measuring body temperature

An electronic clinical thermometer capable of executing plural temperature prediction functions in which elapsed measurement time is a variable, each function prescribing a temperature change up to a final, stable temperature. One of the temperature prediction functions is set, and actual body temperature is sensed at a specific point in time. Then, based on the sensed temperature and selected function, a final temperature is obtained at least twice in accordance with a time series and the temperatures are compared to obtain a difference between them. When the difference falls outside prescribed limits, a new temperature prediction function is selected, a final temperature is obtained based thereon, and the foregoing process is repeated until a difference is found which lies within the prescribed limits. The final temperature obtained at such time is delivered as an output indicative of measured temperature.

An electronic clinical thermometer having a store of plural temperature prediction functions in which elapsed measurement time is a variable, each function prescribing a temperature change up to a final, stable temperature. Temperature at a specific point in time is predicted in accordance with a selected temperature prediction function based on a temperature at a specific sampling instant and elapsed measurement time up to the past sampling instant. The predicted value and a value actually measured at the specific point in time are compared to obtain a difference between them. When the difference falls outside prescribed limits, another temperature prediction function is selected, a subsequent predicted value is obtained based thereon, and the foregoing process is repeated until a difference is found which lies within the prescribed limits. When this occurs, a predicted value of the final, stable temperature corresponding to the prediction function is obtained and delivered as an output.

An electronic clinical thermometer successively stores the temperature detected at a portion of a body, measures the time which has elapsed since start of measurement, and reads the detected temperature, corresponding to a prescribed length of past time, out of a storage to obtain a mean value during the length of past time. The thermometer repeats, at a predetermined period, a process of obtaining and displaying a predicted value of a stable temperature from the mean detected temperature and elapsed measurement time on the basis of a stable temperature prediction function in which measurement time is a variable, the temperature prediction function defining a temperature change up to a final, stable temperature. The prediction computation is halted when, after the elapsed measurement time has exceeded a prescribed magnitude and a difference exhibited by the mean detected temperature corresponding to two points in time no longer shows an increase outside a prescribed range, the detected mean temperature corresponding to a present point in time exhibits a decrease outside a prescribed range in being compared with the mean detected temperature at the preceding point in time.

A measuring apparatus is equipped with an input/output unit for delivering data to externally located equipment and for receiving data from the externally located equipment, or with an input unit for receiving data from the externally located unit, and is adapted to generate correlation data between data delivered by a sensing system provided within the measuring apparatus proper, and data delivered by a standard measurement system which can be disconnected from the measuring apparatus. The correlation data is generated by a data processing device located outside or located within the measuring apparatus, through the intermediary of the input/output unit or the input unit. The generated correlation data is stored, in non-volatile fashion, in a storage section located in the measuring apparatus, in such a manner that the data can be read out of the storage section in response to the data from the sensing system contained within the measuring apparatus.

Ultrasonic waves are applied to a test liquid of an unknown density, and the acoustic parameters of the liquid are measured. The difference is then detected between the acoustic parameters of the test liquid and those of a standard liquid of the same temperature. The difference thus detected is added to the known density of the standard liquid, thereby obtaining the density of the test liquid.
