[0044] See figure 1 , a kind of dry chemical detection test paper 100 provided in this embodiment, it comprises and stacks up together longitudinally: upper substrate 110, middle layer and lower substrate 140, and upper substrate 110 is provided with a plurality of sampling holes 111 that are arranged at intervals . Usually, the middle layer includes one functional layer or more than two functional layers stacked together longitudinally. In this embodiment, the middle layer includes a blood filter layer 120 stacked longitudinally together for filtering blood cells. In some other embodiments, the intermediate layer is only the reactive layer 130, or according to actual needs, the intermediate layer may also include other functional layers. Each functional layer of the intermediate layer is a porous material film, and the pores in the barrier area are irreversibly closed. Each functional layer of the intermediate layer includes multiple detection areas and corresponding barrier...

Abstract

The embodiment of the invention provides dry chemical detection test paper and a preparation process, and relates to the field of dry chemical detection. The dry chemical detection test paper comprises an upper layer substrate, a middle layer and a lower layer substrate which are sequentially stacked in the longitudinal direction, and a plurality of sample adding holes formed at intervals are formed in the upper layer substrate; the middle layer comprises a plurality of detection areas and blocking areas, the middle layer is a porous material film and is formed by irreversible hole closing treatment on pores of the blocking areas, the pores of the detection areas can allow liquid to permeate from the sample adding holes and diffuse in the longitudinal direction and the transverse direction, and each blocking area correspondingly surrounds the periphery of the corresponding detection area and limits the transverse diffusion boundary of the liquid; the lower substrate is provided with aplurality of detection holes. The preparation process of the dry chemical detection test paper mainly comprises the following steps: sequentially stacking the layers together, and carrying out hole closing treatment on pores of the barrier region of the middle layer, or carrying out hole closing treatment and then stacking. The structure and the process are simple, and independent detection of each detection area can be realized without mutual interference.

Description

technical field [0001] The application relates to the field of dry chemical detection, in particular to a dry chemical detection test paper and a preparation process. Background technique [0002] Dry chemical detection test paper is widely used in the detection of biochemical projects because of its convenient use, simple operation and rapid detection. According to the flow path of the liquid sample on the dry chemical detection test paper, the dry chemical detection test paper can be divided into various types, and the vertical vertical detection test paper is one of them. The vertical vertical detection test paper is to stack the carriers with detection reagents on top of each other, and the liquid sample flows through each detection reagent layer from top to bottom, and finally displays the detection results. According to the number of samples that can be measured at one time and the types of measurement indicators, dry chemical test paper can be divided into single tes...
