Component measuring instrument and chip
First Claim
1. A component measuring instrument used by mounting therein a chip comprising a puncture needle and a contact portion for making contact with a specimen sampling portion, comprising:
- a specimen sampling portion application portion which is capable of having a specimen sampling portion to be punctured applied thereon;
puncturing means for moving said puncture needle to puncture the specimen sampling portion applied onto said specimen sampling portion application portion;
pressure reducing means for putting the punctured portion of the specimen sampling portion punctured by said puncture needle, together with a containing space for said puncture needle, into a reduced-pressure condition;
measuring means for measuring the amount of a predetermined component in a blood sample from the punctured portion; and
a chip retracting mechanism for moving said chip, including said puncture needle and said contact portion, in a direction away from the specimen sampling portion, said contact portion being kept in contact with a surface of the specimen sampling portion as said chip moves in said direction so as to maintain said reduced-pressure condition generated by said pressure reducing means.

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.
