Abstract:
1. A collector and sensor for blood component analysis comprising: a substrate having a through hole; a spacer having a through hole; a cover; and a reagent layer, the cover being disposed on the substrate with the spacer intervening between the cover and the substrate, whereby a space between the substrate and the cover that communicates with the through hole of the spacer forms an analysis portion and a channel for leading a blood sample to the analysis portion inside the collector and sensor, with the reagent layer being disposed in the analysis portion, and the cover being breakable by a needle or a lancet, whereby a downwardly protruding burr of the broken cover forms a path for the blood sample from a blood collection part to the channel to the analysis portion, the through holes in the substrate and the spacer forming a common through hole through which the needle or an edge of the lancet and the burr of the broken cover can pass to the blood collection part when the spacer is disposed on the substrate that is placed over the blood collection part, the through hole of the spacer communicating with the channel and a top of the through hole of the spacer being covered with the cover, whereby a lancing portion is formed by the common through hole and a portion of the cover covering the top of the through hole of the spacer, wherein the portion of the cover forming a part of the lancing portion is hydrophilic, and wherein in use, the collector and sensor is placed at a position where blood collection is to be performed, the portion of the cover covering the lancing portion is broken through with the needle or the edge of the lancet so that the needle or the edge is allowed to pass through the common through hole to puncture the position, and the blood sample that has come out is guided by the burr formed when the cover is broken through so that the blood sample is led to the channel and flows through the channel to be led to the analysis portion.
