Abstract:
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.
