Embodiment 1
[0034] This embodiment is an electrochemical biosensor, specifically a whole blood lactate / glucose multifunctional test strip.
[0035] figure 1 It is a schematic diagram of the structural decomposition of the test strip. Such as figure 1 , figure 2 and image 3 , the whole blood lactate / glucose multifunctional test strip of the present invention includes test electrode sheets, cover sheets 7a, 7b and reaction reagent layers 8a, 8b.
[0036]The test electrode sheet includes an insulating substrate 4, on which a pair of thin film conductive strips 5a, 5b and 5c, 5d are respectively formed on the front and back sides of the insulating substrate 4 along the length direction by a method of shielding and a metal thin film deposition process; The conductive strips are parallel to each other. One end of the conductive strip is the input end. (Conductive strips can also use screen printing method to print electrodes with silver paste or stone black carbon paste.) There is an in...
Embodiment 2
[0041] This embodiment provides a mass-produced whole blood lactate / glucose multifunctional test strip.
[0042] The multifunctional test strip of the present embodiment has the same structure as that of embodiment 1, including insulating substrate 4, film conductive strips 5a, 5b, 5c and 5d, insulating gaskets 6a, 6b, 6c and 6d and cover sheets 7a, 7b, They respectively form capillary cavities 9 a and 9 b with both ends opened on both sides of the insulating substrate 4 . One end of the film conductive strip is the input end.
[0043] In mass production, use three equal-length and equal-width sheets of insulating organic material, or three rolls of equal-width organic insulating sheets (films). The size of each sheet (roll) is convenient for processing and as much as possible. A single test strip unit is suitable. Among them, at least two pieces (rolls) are transparent materials, which are used as the production material of the cover sheet. Among them, it is necessary to m...
Embodiment 3
[0047] This example is an integrated blood collection needle packaged with a whole blood lactate / glucose test strip.
[0048] Integrated blood collection needles, such as Figure 4 , Figure 5 As shown, it includes a whole blood lactate / glucose test strip 1 , a needle stick 2 and a blood collection needle tip 3 .
[0049] Such as Figure 6 , Figure 7 As shown, the needle bar 2 is formed by injection molding or compression molding of organic materials, and its diameter is equal to the width of the whole blood lactate / glucose test strip 1. One end of the needle bar 2 has a mounting hole 11, and the blood collection needle point 3 is installed in the hole. 3 is an ordinary spear-shaped blood collection needle point, and the spear-shaped blood collection needle point 3 is inserted into the installation hole 11 and then fixed. The other end of the needle bar 2 is a U-shaped slot 10 open on three sides, the depth of the U-shaped slot 10 is the same as the length of the whole bl...
