Biological information measurement cartridge and measurement device using same
First Claim
1. A biological information measurement cartridge comprising:
- a cartridge main body including a first end side, a second end side, and a surface;
a sensor unit provided on the first end side of the cartridge main body; and
a protective cap removably provided on the first end side of the cartridge main body;
the cartridge main body including;
a puncture opening including a back, and being disposed on the first end side of the cartridge main body;
a puncture needle provided at the back of the puncture opening; and
a puncture needle retainer configured to retain the puncture needle such that the puncture needle is slidable toward the puncture opening;
the sensor unit including;
a depositing opening disposed on the first end side of the cartridge main body;
an introduction channel configured to communicate with the depositing opening; and
an introduction promoting hole configured to communicate with the introduction channel and open at a part of a surface of the sensor unit; and
the protective cap including;
a puncture needle protector in which the puncture needle of the cartridge main body is to be inserted; and
a sensor protector configured to close the depositing opening and the introduction promoting hole in a sealed state by contacting the sensor unit;
wherein;
a recessed portion is defined between the puncture needle and the sensor unit on the first end side of the cartridge main body;
the puncture needle and the sensor unit are spaced apart at a predetermined distance by the recessed portion in a direction that is orthogonal to a longitudinal direction of the cartridge main body;
the sensor protector includes a first bottom portion, an outer peripheral wall, an annular insertion receiving portion, and a protruding portion configured to be inserted into the recessed portion;
the outer peripheral wall includes a first bottom portion side and protrudes toward the second end side of the cartridge main body;
the annular insertion receiving portion is defined by connecting two side surfaces of the protruding portion to the first bottom portion side of the outer peripheral wall; and

Abstract
A rectangular parallelepiped-shaped cartridge main body having a protective cap removably attached to a first end side thereof has a puncture needle retainer that retains a puncture needle provided at the back of a puncture opening provided on the first end side of the cartridge main body such that the puncture needle is slidable toward the puncture opening. Furthermore, a sensor unit having a depositing opening is provided on the first end side of the cartridge main body. The sensor unit has an introduction promoting hole that communicates with an introduction channel communicating with the depositing opening and that opens to the surface of the cartridge main body. The protective cap is provided with a puncture needle protector that covers the puncture needle, a sensor protector that covers the depositing opening of the sensor unit, and a sensor protector that covers the introduction promoting hole.
