In a chromatography quantitative measuring apparatus according to the present invention, a beam applied from a light source to a chromatography test strip is formed into an elliptical shape by an optical means such as a cylindrical lens, a variation in absorbance that accompanies elution of a marker regent is detected while the elliptical beam is applied between a marker reagent hold part and a detection part, and a measurement is automatically started in a prescribed period of time since the detection of variation. According to the chromatography quantitative measuring apparatus so configured, non-uniform coloration is reduced by shaping the beam elliptically with the optical means, whereby the accuracy of quantitative analysis is enhanced, and the apparatus can be operated easily.

Chromatography quantitative measuring apparatus

A puncturing apparatus includes a housing having a first case and a second case, the housing configured to move at least one of the first case and the second case so that the cases are in an overlapping state in which the first case and the second case overlap one another or a non-overlapping state. A puncturer is housed in the housing and a puncture starting mechanism, having a puncturing button, is configured to activate the puncturer. A first safety section is configured to prevent at least one of the puncturing opening and the puncturing button from being exposed, by placing the first case and the second case in the overlapping state, and a second safety section is configured to disable operation of the puncture starting mechanism in the non-overlapping state of the first case and the second case.

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.

By measuring a luminance difference between predetermined two points or a luminance variation in a predetermined region in a state in which a liquid sample is developed in a chromatography specimen, and comparing the luminance difference or the luminance variation with a preset reference value, it is possible to automatically detect degradation such as a decrease in hydrophilicity in the lower portion of a liquid-impermeable sheet materialduring a chromatography inspection, thereby enabling an accurate inspection.

A blood test device using a laser as a puncture member. More specifically, in a blood test device using a laser as a puncture member, the skin can be fixed at a definite position by raising the punctured skin under negative pressure, and thus the skin is brought into close contact with a blood sensor and the laser is focused on the vicinity of the blood sensor face. Thus, it is possible to provide a blood test device of the laser puncture type in which the skin can be surely punctured while giving little pain to a patient.

Blood test device

A laser perforation device that has a simple structure and with which pain to a person in skin perforation is reduced. In the device, a laser beam emitted from a laser emitting device is branched into laser beam paths by splitters and mirrors and pierces skin by applying the split beams to the same position on the skin. Since the skin is pierced by a laser beam with a low output, pain to the person can be reduced.

Laser perforation device and laser perforation method

Provided is a liquid sample analyzing method for analyzing an analyte in a liquid sample by using a test piece () on which overflow blocking lines () are formed to prevent the liquid sample from flowing to the outside from a passage region () of an extended layer (). In a state in which the liquid sample is not extended in the passage region () of the extended region (), the test piece () is measured so as to cross the passage region () of the extended layer () and the overflow blocking lines (). Thus in a state in which a difference in brightness is large between the passage region () of the extended region () and the overflow blocking lines (), it is possible to properly recognize the boundary portions between the passage region () of the extended region () and the overflow blocking lines ().

Liquid sample analyzing method

Provided is a device in which light from a samplefixed in a test pieceis captured by an image sensorthrough an optical system made up of a lens, a diaphragm, and so on and concentration information is obtained, wherein a wide-band light sourcefor illuminating the test pieceis combined with an optical filterfor optionally selecting a wavelength of the light captured by the image sensor. Thus it is possible to reduce a measurement error caused by a change of the light quantity distribution of the light source

Analyzing device and analyzing method

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). Thus, the skin rises and comes into contact with a second skin contact sensor (time point). After piercing into the skin at time point, the negative pressure supply is once ceased. Next, the negative pressure is applied again at time pointfor a definite period of time. Thus, the opening in the skin is broadened, which facilitates the flow out of the blood ().
