A body fluid sampling apparatus (A), comprising a piston ( ) provided in a tubular main case ( ), a first plunger rod ( ) extending into the piston ( ) integrally with each other; a first spring ( ) elastically energzing the piston ( ) toward the upper end side, a second plunger rod ( ) installed in the first plunger rod ( ) through a second spring ( ), a lancet mounted body ( ) provided on the second plunger rod ( ) and having a lancet (B) mounted therein, a third spring ( ) elastically energizing the lancet mounted body ( ) toward the upper end side, latch mechanisms ( ) suppressing the second plunger rod ( ) and first plunger rod ( ) when the first plunger rod ( ) is moved to the lower end side by he push-down of the piston ( ), and a release mechanism ( ) for releasing the locked state of the first plunger rod ( ) and the second plunger rod ( ).

Body fluid sampling apparatus

An article of manufacture includes a computer usable medium, including computer-readable program code instructions embodied therein, for causing a computer to manage data in a measuring apparatus. The instructions include a detecting portion utilized for causing the computer to detect whether an electrode has been mounted on the measuring apparatus. A characteristic measuring portion is utilized for causing the computer to measure a characteristic of the electrode to determine what type of electrode has been mounted on the measuring apparatus. A clocking portion is utilized for causing the computer to clock a first period of time after the computer has measured the characteristic of the electrode. A determining portion is utilized for causing the computer to determine whether to measure density of an element included in a biological body fluid or whether to read out measured density data. A density measuring portion is utilized for causing the computer to measure density of the element included in the biological body fluid which has been placed on the electrode. A density storing portion is utilized for causing the computer to store a measured density of the element included in the biological body fluid in a storing device. A read out portion is utilized for causing the computer to read out measured density data stored in the storing device.

A sensor 13 is inserted into a connector 14. A constant voltage required to obtain a response current is applied across the connector 14 by a voltage applying source 15 at timings required. A response current of the sensor 13 inserted into the connector 14 is converted into a voltage by a current-to-voltage converter 16, and the amount thereof is determined by a microcomputer, the analysis results being displayed onto a display unit.

Quantitative analysis method and its system using a disposable sensor

An autonomous continuous analysis method and apparatus using Dip and Read type analytical implements. A series of operations of taking out analytical implements, dipping them in the sample solution, optical measurement, calculation, and disposal of the used sample solution are performed automatically. The dip stage, in particular, is automated by use of an analytical-implement automatic supply device and an analytical implement automatic handling device which, holding an analytical implement, dips it in the sample solution, and sets it ona reaction turntable. A number of analytical implements are put in a storage section comprising a bottom section provided with an analytical implement groove and at least one inside surface which is parallel with the groove, are taken out one by one by the relative movement of the groove and in normal and reverse direction and by stopping in a specified position after confirming by a detector that an implement has been caught in the groove.

The test solution in the measuring cell is regarded to be divided into a plurality of sections, and the quantity of scattered light from each section is continuously measured to give a plurality of independent series of signal. This measurement is carried out by scanning the measuring cell with a minute light flux periodically to obtain a plurality of measurements in a period. Out of the series of signals obtained, those containing abnormal scattered light signal are eliminated to determine accurate concentration and reaction process.

Method of measurement using scattered light

A method for accurately performing concentration measurements while compensating the dilution ratio as needed during continuous measurement of specified ingredient in the liquid to be tested. The liquid to be tested is diluted by a diluent, wherein the liquid to be tested and the diluent or the mixture of the two and the diluent is transferred by means of the respective tube pumps to a measuring section. Either or both of the quantities of liquid-feeding of those two liquids are changed at the beginning of measuring or in an optional stage during the time of the measurement, diluted and mixed at two or more dilution ratios. Then the real dilution ratio at the time of changing the quantities of the said liquids is found on the basis of the measured value of the substance to be measured at the respective dilution ratios, and the concentration of the substance contained in the liquid to be tested is determined by using the real dilution ratio.
