Abstract: A blood testing meter with a fool-proofing function has a measuring display unit, a connector and a blocking structure. The connector is mounted in the measuring display unit and has at least one guiding groove, and the at least one guiding groove is formed through an outer side of the measuring display unit. The blocking structure is mounted on the outer side of the measuring display unit and is adjacent to an opening of the connecting groove. When the blood test strip is inserted from a wrong direction into the connector, the slot would be engaged with the blocking structure to prevent the blood test strip from being inserted into the connector.

Abstract: The invention is related to an examining test paper which comprises an upper substrate, a lower substrate, an upper insulation sheet, a lower insulation sheet and a separator. Each of the upper and lower substrates comprises surface, a notch, a connection area, a reaction area, and an electrode layer. The notch is recessed on a proximal end. The connection area is adjacent to the notch. The reaction area and the electrode layer are defined on the surface. The upper and lower insulation sheets are respectively connected to the upper and lower substrates, and each comprises an upper surface, a lower surface, and a permeation portion. The separator is connected to the upper and lower insulation sheets and comprises two permeation portions corresponding to the permeation portions of the upper and lower insulation sheets, respectively.
