Abstract
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.
