Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
In embodiment, as it is shown in figure 1, a kind of paper substrate micro fluidic device, including reagent paper, described reagent paper is provided with hydrophilic area 1,
The edge of described hydrophilic area 1 is provided with the center of hydrophilic area 1 described in a hydrophobic border 2 and is provided with sample-adding circular hole 11, described sample-adding circle
The outer rim in hole 11 is communicated with the capillary channel 12 of some circumference array, and the outer end of some described capillary channels 12 is all communicated with detection
Hole 13.Each capillary channel 12 of the present embodiment has a length and width communicated, and the size also phase in each detection hole 13
With, time therefore by reagent paper horizontal positioned, the sample liquid hold-up theory in each detection hole 13 is identical, adds in difference detection hole 13
Different fluorescent probes, just can reach to detect Multiple components or the purpose of ion, it is achieved variation detection.
In embodiment, as it is shown in figure 1, a diameter of 6mm of described sample-adding circular hole, some described capillary channels are wide isometric,
The width of shown capillary channel is 2mm.In the present embodiment, all of capillary channel 12 is wide isometric, it is ensured that in detection hole 13
Sample liquid hold-up is identical.
In embodiment, as shown in Figure 1 and Figure 2, a described hydrophobic border 2 is wax floor, the width on a described hydrophobic border 2
Degree is 3mm.The present embodiment selects wax layer as hydrophobic layer, has easy to process, the convenient passage of Waste Paper Handling.
In embodiment, as in figure 2 it is shown, the lower section of described reagent paper is provided with hydrophobic layer 3, described hydrophobic layer 3 is adhesive tape.This enforcement
The hydrophobic layer 3 of example prevents the paper of the saturating reagent paper of sample immersion from carrying on the back.
In embodiment, as it is shown in figure 1, described reagent paper is provided with some hydrophilic contrast districts 4, described contrast district 4 outer rim sets
There are No. two hydrophobic borders 5.The contrast district 4 of the present embodiment is used for accommodating sample liquid, whether can send fluorescence by direct visual comparison fluorescent probe.
Obviously, above-described embodiment of the present utility model is merely to illustrate that this utility model example, and not
Restriction to embodiment of the present utility model.For those of ordinary skill in the field, on the basis of described above
On can also make change or the variation of other multi-forms.Here without also all of embodiment being given poor example.
And these belong to obvious change that connotation of the present utility model amplified out or variation still falls within this utility model
Protection domain.
