First Claim
Patent Images
1. A blood test apparatus, comprising:
- a housing with an opening part;
a puncturer that is provided inside the opening part;
a first sensor that detects contact between a part to be punctured and a front surface of the opening part;
a negative pressure generator that creates a negative pressure inside the opening part;
a blood sensor that samples blood flowing out from the part punctured with the puncturer after the negative pressure is created inside the opening part by the negative pressure generator; and
a measuring circuit that measures a signal obtained from the blood sensor to analyze components in the blood, wherein;
the blood sensor is positioned to project from the front surface of the opening part and is mounted for movement in and out of the housing through the opening part;
the first sensor is configured to detect that the blood sensor is forced into the opening part by the part to be punctured; and
the negative pressure generator starts when the first sensor detects that the blood sensor is forced into the opening part.

Abstract
A blood test apparatus negatively pressurizes a vicinity of a site to be punctured for collecting blood at an appropriate time without resorting to a special operation. More specifically, a blood test apparatus includes a housing having an opening; a puncturer; a first sensor that detects contact of a front face of the opening with a site to be punctured; a negative pressure generator that negatively pressurizes an inside of the opening; and a blood sensor that collects blood. The negative pressure generator starts when the first sensor detects the contact of the front face of the opening with the site to be punctured.
