BLOOD TESTING DEVICE
First Claim
1. A blood test apparatus comprising:
- a housing;
a laser emitting device that is provided in the housing and that punctures skin with laser light in a noncontact state;
a blood sensor that analyzes blood exuding by puncturing;
a holding section that holds the blood sensor;
a negative pressure chamber that is provided in the holding section and through which the laser light from the laser emitting device penetrates;
a negative pressure means that creates a negative pressure in a negative pressure space hermetically sealed between the skin and the negative pressure chamber; and
a cover unit that is removably mounted to the negative pressure chamber,wherein the cover unit includes;
a cylindrical member that encloses an optical axis of laser light from the laser emitting device and has a predetermined length in a direction of the optical axis;
a cover member that is disposed at the end of the cylindrical member in the laser emitting device side, on the optical axis of laser light from the laser emitting device; and
a communication path that communicates an inside of the cylindrical member with the negative pressure chamber.

Abstract
A blood testing device that can perform blood testing having lighting intensity independent of the number of times of piercing. The blood testing device (21) has a cover unit (20) removably installed on negative pressure chambers (25a, 25b). The cover unit (20) has a circular tube section (20b) surrounding the optical axis of a laser unit (26) and having a predetermined length in the direction of the optical axis, a cover glass (20d) placed on the optical axis of the laser unit (26) so as to be located at that end of the circular tube section (20b) which is on the laser unit (26) side, and a slit (20e) for interconnecting the inside of the circular tube section (20b) and the negative pressure chamber (25a) outside the circular tube section (20b).
