Abstract: A lancet is pressed against a puncture needle cartridge while fitting a puncture needle loading inlet of the lancet to the axis of a puncture needle on the puncture needle cartridge. In order to facilitate the operation, one of plural puncture needles, arranged in parallel, is tilted up from its initial position at a predetermined angle, and the puncture needle is guided into a puncture needle holding rod of the lancet. Simultaneously, the puncture needle is pressed up to a position where the rear end part of the needle pushes the bottom surface of a puncture needle loading chamber of the puncture needle holding rod, whereby the puncture needle is loaded. When discarding a used puncture needle, the puncture needle is inserted into a lancet guide member of the puncture needle cartridge, whereby the puncture needle is reliably captured to be discarded.

Abstract: A lancet having a slider with a puncture needle holding mechanism at one end thereof, and having a cam ring with a continuous cam groove, rotatable about a support shaft, and with a cam ring claw and an anti-return claw restricting the rotation. The lancet also having a ring spring applying a force to rotate the cam ring, having a rotatable stopper arm holding and releasing the rotation of the cam ring, and having a rotatable ratchet restricting the direction of rotation of the cam ring. A puncture needle unit including a puncture needle body integrally molded with a protrusion fitted to the lancet, a rotation stop rib, a puncture needle, and a puncture needle cap lightly pressed into the puncture needle body.

Abstract: It is intended to make it easy to recognize the attachment site of a blood sensor in a blood test device to which the blood sensor is attached by insertion. Especially, it is attempted to make the recognition of the attachment site easy and facilitate the insertion of a blood sensor which is to be attached to a blood test device by a person with visual impairment (in particular, a patient suffering from diabetic retinopathy) for the daily measurement of blood glucose level. More specifically speaking, it is intended to provide a blood test device comprising a housing; an electrical circuit unit contained in the housing; and an attachment site for inserting a blood sensor thereinto that is exposed on the surface of the housing; wherein the surface of the attachment site has a color which is lighter than the surface color of the housing and distinguishable by a patient having impairment in the blue cone.
