Blood test apparatus
First Claim
1. A blood test apparatus comprising:
- a housing;
a measuring circuit accommodated in the housing;
two or more connectors electrically connected to the measuring circuit;
an attaching part formed in one side of the housing;
a plunger that moves back and forth in the housing;
a lancet, one end of the lancet is held by the plunger so as to allow the one end to be inserted into and removed from the plunger;
a blood collection needle attached to the other end of the lancet;
a holder that is held by the attaching part so as to allow the holder to be inserted into and removed from the attaching part and that allows the lancet to move inside the holder; and
a blood sensor that is attached to one end of the holder and that has two or more connection electrodes, wherein;
the lancet, the blood collection needle and the blood sensor are integrated with the holder to constitute a blood sampling cartridge that can be detachably inserted into and removed from the attaching part;
two or more connectors are arranged so as to be in contact with the connection electrodes of the blood sensor,contact parts of the two or more connectors that contact with the connection electrodes of the blood sensor are arranged around a specific point and arranged at equiangular intervals centered on the specific point;
the specific point is a center of rotation with respect to an axis of an insertion direction for attaching the blood sampling cartridge to the attaching part;
one of the two or more connection electrodes includes a reference electrode; and
wherein the measuring circuit determines the positions of the two or more connectors relative to the two or more connection electrodes by determining which of the two or more connection electrodes includes the reference electrode and identifying which of the two or more connection electrodes contacts which of the two or more connectors.

Abstract
A blood test apparatus wherein a blood collection needle and a blood sensor can be easily attached and detached so that a burden or pain of a patient can be relieved. More specifically speaking, a blood test apparatus wherein a holder, a lancet, a blood collection needle and a blood sensor are united together as a blood sampling cartridge that is detachably mounted to the apparatus body. When this blood sampling cartridge is attached, a plunger involved in the apparatus body holds the lancet and connectors involved in the apparatus body come into contact with the blood sensor. It is preferable that the contact points with the blood sensor of the individual connectors are located at intervals at the same angle centering on a definite point.
