A blood test device using a laser as a puncture means. More specifically, it is intended to provide a blood test device using a laser as a puncture means by which the skin can be fixed at a definite position by raising up the punctured skin under negative pressure and thus bringing it into close contact with a blood sensor and in which the laser is focused into the vicinity of the blood sensor face. Thus, it is possible to provide a blood test device of the laser puncture type whereby the skin can be surely punctured while giving little pain to a patient.

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.

The particle counter (20) and the ESR measuring section (30) being arranged in parallel.

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 usable both for a blood inspection device that performs puncture with a puncturing needle and for a blood inspection device that performs puncture with laser. In concrete, this invention comprises a sensor unit having a holder and a blood sensor mounted to the holder and a needle unit having a slidable puncturing needle. The needle unit provides a blood sensor block detachably fitted to the inside of the holder of the sensor unit. The blood sensor block is applied to a needle-puncturing type blood inspection device. The sensor unit from which the needle unit is removed is applied to a laser-puncturing type blood inspection device.

A sensor holder comprises a sensor mounting part having a first face on which a blood sensor is placed, a second face provided on the opposite side from the first face, and a through-hole that goes from the first face to the second face and is large enough to allow a laser beam to pass through; a finger holding part that is provided on the second face and surrounds the through-hole, and a grip that sticks out from the blood testing device when the sensor holder is mounted to the blood testing device.

A blood sensor to be used in a blood test apparatus, more specifically speaking, a blood sensor which can be easily attached to a blood test apparatus and detached therefrom. Namely, a blood sensor to be detachably attached to a blood test apparatus having a plural number of connectors, which comprises: a supply channel to which blood is supplied; a detection section provided in the supply channel; a plural number of detection electrodes formed in an area including the detection section; a plural number of connection electrodes electrically connected to the detection electrodes respectively; and a standard electrode serving as a standard for differentiating these connection electrodes. The connectors are connected respectively to the connection electrodes and the standard electrode of the blood sensor having been attached to a definite position of the blood test apparatus.

A blood test device whereby a used sensor can be discarded without staining the holding part after the completion of blood measurement. In this device, a blood sensor (23), which collects blood oozing out from the punctured skin and analyzes the blood components, is held between a first holder (25a) and a second holder (25b). The second holder (25b) is provided in a movable manner along the direction of closing to and separating from the first holder (25a). By a pressing projection (20b), the second holder (25b) is moved so that the second holder (25b) is separated from the first holder (25a). At the same time, the blood sensor (23) is separated from both of the first holder (25a) and the second holder (25b) and supported by supporting claws (20c). Thus, a gap is formed between the first holder (25a) and the second holder (25b) as described above.

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).

This blood examination apparatus examines cancer cells mixed in an examination object which is flowing blood, and includes: a flow cell through which the examination object is made to flow; an imaging optical system which light output from the examination object in an examination region in the flow cell enters, the imaging optical system forming an image of the light on a first image plane; a first Fourier transformation optical system which optically two-dimensionally Fourier-transforms the image formed on the first image plane by the imaging optical system to form the Fourier-transformed image on a second image plane; a spatial light filter which selectively allows a portion in a certain range around an optical axis of the first Fourier transformation optical system of the image formed on the second image plane by the first Fourier transformation optical system to pass through; and a second Fourier transformation optical system which optically two-dimensionally Fourier-transforms the portion which has passed through the spatial light filter of the image formed on the second image plane by the first Fourier transformation optical system to form the Fourier-transformed image on a third image plane.
