BLOOD TEST METHOD AND BLOOD TEST APPARATUS
First Claim
1. A blood test apparatus comprising:
- a housing with an opening part;
a puncturing section that is arranged inside the opening part;
a first sensing section that detects a contact between a part to be punctured and a front surface of the opening part;
a negative pressure section that creates a negative pressure inside the opening part;
a blood sensor that samples blood flowing out from the part punctured with the puncturing section after the negative pressure is created inside the opening part by the negative pressure section; and
a measuring circuit that measures a signal obtained from the blood sensor to analyze components in the blood, wherein;
the blood sensor is arranged projecting from the front surface of the opening part and held so as to be able to move in and out of the housing through the opening part; and
the negative pressure section starts when the first sensing section detects a contact between the part to be punctured and the front surface of the opening part.

Abstract
It is intended to provide a blood test apparatus whereby the vicinity of a site to be punctured for collecting the blood can be negatively pressurized and the negative pressurization can be conducted at an appropriate time without resorting to a special operation, thereby facilitating a blood test. More specifically speaking, a blood test apparatus which comprises: a housing having an opening: a puncture means located in the opening; a first sensing means whereby the contact of the front face of the opening with a site to be punctured is detected; a negative pressurization means whereby the inside of the opening is negatively pressurized; a blood sensor whereby the blood, that flows out from the punctured site having been punctured by the puncture means after negatively pressurizing the inside of the opening by the negative pressurization means, is collected; and a measurement circuit whereby a signal obtained from the blood sensor analyzing components in the blood is measured, wherein the negative pressurization means starts up when the first sensing means detects the contact of the front face of the opening with the site to be punctured.
