A blood sensor including a base (12), a detection part (16) disposed on the base (12), a blood collection needle (13) disposed at a front end (12a) of the base (12), a negative pressure generation part (17) for applying negative pressure to a portion of the blood collection needle (13), and a supply path (15) for supplying blood collected by the blood collection needle (13) to a detection part (16).

A blood test apparatus having a simple constitution whereby stable measurement can be conducted by surely sampling the blood in an amount being small but sufficient for the test without placing too much burden on a patient. When a first skin contact sensor of this apparatus detects the skin, driving of a negative pressure unit is initiated (time point 166a). Thus, the skin rises and comes into contact with a second skin contact sensor (time point 166b). After piercing into the skin at time point 166c, the negative pressure supply is once ceased. Next, the negative pressure is applied again at time point 166d for a definite period of time. Thus, the opening in the skin is broadened, which facilitates the flow out of the blood (16).

The present invention relates to a test socket with a high density conduction section, and more particularly the test socket arranged between a blood test device and a test apparatus for electrically connecting the terminal of the blood test device and the pad of the test apparatus includes: a first electrical conduction part arranged at the position corresponding to the terminal of the blood test device consisting of a plurality of first electrical conduction particles arranged in the direction of the thickness in a resilient material; a resilient electrical conduction sheet including an insulation support part for supporting the first electrical conduction part by insulating an adjacent first electrical conduction part; a support sheet attached to the upper side of the resilient electrical conduction sheet having a through-hole formed at every position corresponding to the terminal of the blood test device; and a second electrical conduction part filling the through hole of the support sheet consisting of a plurality of second electrical conduction particles arranged in the direction of the thickness in a resilient material, characterized in that the second electrical conduction particles are arranged in the resilient material with a higher density than the first electrical conduction particles, and the though holes have the upper end with a larger diameter than that of the lower end.

A blood inspection device using laser as puncture means. The blood inspection device has an electric power source control circuit for controlling electric power supply of an electric power source section including an electric power source for driving an electric circuit for measurement and also including an electric power source for driving a laser emission device. When a battery is used as the electric power source, the circuit measures the remaining level and voltage of the battery to control the power source so that electric power shortage does not disenable measurement.

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.

The present invention relates to a test socket that is disposed between a blood test device and a test apparatus to electrically connect a terminal of the blood test device and a pad of the test apparatus with each other. Conduction units that are arranged at positions corresponding to the terminal of the blood test device and show conductivity in a thickness direction have: conduction units that are arranged in such a manner that multiple conductive particles are arranged in the thickness direction in an elastic insulating material; and an insulating support unit that supports and insulates each of the conduction units. The conductive particles are provided with through-holes bored through one surface and another surface other than the one surface, and the through-holes are filled with the elastic insulating material.

A blood sensor (20a) comprises a substrate (21); a spacer (22) attached to the top of the substrate (21); a cover (23) attached to the top of the spacer (22); a blood reservoir portion (24) defined by a substrate hole (21a) formed in the substrate (21), a part of a spacer hole (22a) formed in the spacer (22) and connected to the substrate hole (21a), and a cover hole (23a) formed in the cover (23) and connected to the spacer hole (22a); a supply passage (25) defined by another part of the spacer hole (22a) and communicating with the blood reservoir portion (24); and detection electrodes formed in the supply passage (25). The cover (23) projects from the supply passage (25) toward the inside of the blood reservoir portion (24) farther than the substrate (21) and the spacer (22).
