Abstract:
1. A blood test apparatus configured for puncturing skin measuring blood, the apparatus comprising: a laser puncturing section that emits a laser light to puncture the skin; a blood sensor that collects and analyzes the blood flowing out from the punctured skin, the blood sensor being configured for detecting collection of the blood; a holder that holds the blood sensor; a negative pressure section that creates a first negative pressure in a space near the blood sensor; and a negative pressure controlling section that controls an operation of the negative pressure section, wherein the negative pressure controlling section repeatedly increases the first negative pressure in the space near the blood sensor up to a predetermined maximum negative pressure and reduces the first negative pressure in the space near the blood sensor to a second negative pressure lower than the predetermined maximum negative pressure, in at least a part of a period that extends from when the skin abuts on the holder until when the blood sensor detects the collection of blood.
