It is an object of the present invention to provide a component measuring instrument with which a predetermined component in blood can be measured securely and in a short time. The component measuring instrument, which is used by mounting therein a chip having a puncture needle, includes: a specimen sampling portion application portion to which a specimen sampling portion to be punctured is applied; a puncturer for moving the puncture needle; pressure reducer for putting the punctured portion of the specimen sampling portion punctured by the puncture needle, together with a containing space for the puncture needle, into a reduced-pressure condition; measurer for measuring the amount of a predetermined component in the blood sampled from the punctured portion; and a chip retracting mechanism for moving the chip in a direction away from the specimen sampling portion while maintaining the reduced-pressure condition generated by the pressure reducer.

Component measuring instrument and chip

A body fluid component measuring apparatus capable of accurately measuring a specific component in a body fluid for a short time includes, in a main body, a measuring device for detecting the sampling of a body fluid and measuring a component of the sampled body fluid, and a pump and an electromagnetic valve which constitute an evacuating mechanism. When the sampling of blood is detected, the pump is stopped to release the evacuation state. Another apparatus according to a second aspect includes a pressure detecting means and a notifying device. A puncturing device is operated only when it is decided on the basis of a result of detection by a sensor, that the housing is in an evacuation state, and after the sampling is detected, the evacuation is released and information is notified. A further apparatus according to a third aspect includes a pressure adjusting means for fluctuating the pressure.

Body fluid composition measuring apparatus

An assembly to be detachably mounted on a body fluid monitoring system is provided. The assembly has a lancet and a device for collecting and detecting a body fluid. The lancet has a puncture needle. In this assembly, the puncture needle is maintained in sterilized conditions until its use, and the sterilization can be conducted with no adverse effects on the detection device. A readily sterilizable lancet unit and a body fluid-collecting and detecting unit adapted for use in such an assembly as well as a body fluid-monitoring system including such an assembly are also provided. The assembly comprises a first housing having a sleeve which movably accommodates the lancet in its interior, and a second housing having the body fluid detection device. The first housing and the second housing share an opening. The lancet is sterilized before the assembly. The body fluid-collecting and detecting section has a body fluid guide on the periphery of the inlet.

Assembly having lancet and means for collecting and detecting body fluid

A body-fluid inspection device, which sticks a skin so as to obtain a fine amount of body fluids and measures ingredients of the body fluids, includes a casing having an opening, a sticking device having a sticking needle that is allowed to protrude from the opening of the casing, and a suction device which places at least portion of a space inside the casing in a reduced-pressure state. Also included are a reduced-pressure releasing device for releasing the space inside the casing from the reduced-pressure state, a chip which is detachably attached to the opening of the casing and is provided with test paper for absorbing the body fluids that have been sucked by the body-fluid suction device, a measuring device for measuring ingredients of the body fluids that have been absorbed by the test paper, and a display device for displaying results of measurements made by the measuring device. The display device is placed on one portion of a surface of the casing. The sticking, the suction and the measuring devices are installed inside the casing.
