摘要:
A blood test apparatus having a simple constitution whereby stable measurement can be conducted by surely sampling the blood in an amount being small but sufficient for the test without placing too much burden on a patient. When a first skin contact sensor of this apparatus detects the skin, driving of a negative pressure unit is initiated. Thus, the skin rises and comes into contact with a second skin contact sensor. After piercing into the skin, the negative pressure supply is once ceased. Next, the negative pressure is applied again for a definite period of time. Thus, the opening in the skin is broadened, which facilitates the flow out of the blood.

A blood test apparatus having a simple constitution whereby stable measurement can be conducted by surely sampling the blood in an amount being small but sufficient for the test without placing too much burden on a patient. When a first skin contact sensor of this apparatus detects the skin, driving of a negative pressure unit is initiated (time point 166a). Thus, the skin rises and comes into contact with a second skin contact sensor (time point 166b). After piercing into the skin at time point 166c, the negative pressure supply is once ceased. Next, the negative pressure is applied again at time point 166d for a definite period of time. Thus, the opening in the skin is broadened, which facilitates the flow out of the blood (16).

It is intended to provide a means of easily removing a portion of blood bleeding from pierced skin, which has not been taken into a blood sensor but remained on the skin, in a blood test with the use of a blood test apparatus. By using this means, it becomes unnecessary in the blood test to separately prepare a paper sheet, etc. for wiping off. More specifically speaking, a blood test apparatus wherein a blood sensor is provided within a blood sensor unit detachable to the blood test apparatus body and the blood sensor unit has a part to be in contact with the skin in the test and an absorption means. It is favorable that the part to be in contact with the skin in the test serves as the absorption means.

摘要:
A biosensor system can comprise a sensor chip and a measurement device. The sensor chip comprises a capillary and electrodes disposed within the capillary. The height of the capillary is set to be less than the maximum value of the sum of the diffusion distance of an electron-transfer mediator and the diffusion distance of an analyte at the upper limit of the measurement guaranteed temperature of the biosensor system. The measurement device applies an open circuit voltage, a voltage that is lower than during concentration measurement, or the like to the electrodes of the sensor chip.

The present invention provides: a reagent composition having higher storage stability; a sensor involving the reagent composition; and others. According to the present invention, a specific heterocyclic compound is added to a reagent composition to improve the storage stability of the reagent composition and reduce the degree of fluctuation in current values in a sensor that utilizes reagent composition.
摘要:
According to the standard solution and the determination method of the present invention, in a case where a voltage is applied by a drive voltage of a measurement apparatus to an electrode portion of a biosensor comprising an electrode portion including a counter electrode and a measuring electrode formed on an insulating substrate, and a reagent layer which reacts with a sample solution supplied to the electrode portion, and a current value which flows at the application is measured, thereby determining a substrate contained in the sample solution, a reducing substance is contained in the standard solution used for controlling a precision of measurement of the measurement apparatus. Therefore, when the standard solution is measured, a large change occurs in a current waveform between time t0 and t1 shown in FIG. 6 due to the reducing substance, thereby discriminating whether the analyte liquid being measured is the standard solution or the sample solution and easily identifying the kind of analyte liquid.
摘要:
A sensor chip includes two measuring units. The first measuring unit includes an electrode system having a portion of an electrode and a portion of an electrode, and a portion of a capillary containing the portion and the portion. The second measuring unit includes an electrode system having a portion of a sensor electrode and a portion of an electrode, and a portion of a capillary containing the portion and the portion in addition to a reaction reagent layer. Data related to the temperature of the blood sample is acquired based on the dimension of a current flowing through the temperature electrodes, and data related to a concentration of an analyte in the blood sample is acquired based on the dimension of a current flowing through the analysis electrodes.
