[0025] With reference to Figs. 1-4 , a test card paper includes a base plate 1, a silica gel piece 2, a plurality of color blocks 3, a desiccant 4, and a sealing film 5, wherein an injection groove 11, a detection groove 12, a drying groove 13, and a flow channel 14 are formed on the surface of the base plate 1, and the injection groove 11, the detection groove 12, and the drying groove 13 are connected in communication through the flow channel 14. The flow channel 14 is arranged in a "N" shape and can be divided into a first flow channel section 141, a second flow channel section 142, and a third flow channel section 143, wherein the second flow channel section 142 is located between the first flow channel section 141 and the third flow channel section 143. The end of the first flow channel section 141 is connected in communication with the injection groove 11, the end of the third flow channel section 143 is connected in communication with the drying groove 13, and the detection groove 12 is arranged on both sides of the first flow channel section 141 and connected in communication with the first flow channel section 141. The silica gel piece 2 is arranged at the top end opening of the injection groove 11, the plurality of color blocks 3 are arranged in the detection groove 12, the desiccant 4 is arranged in the drying groove 13, and the sealing film 5 is arranged on the surface of the base plate 1.
[0026] In order to enable the silica gel piece 2 to have a good sealing effect on the top end opening of the injection groove 11, a mounting groove 15 is formed on the surface of the base plate 1, the mounting groove 15 is arranged around the periphery of the injection groove 11, the communication position of the first flow channel section 141 and the injection groove 11 is located at the bottom end of the mounting groove 15, and the silica gel piece 2 is clamped and mounted in the mounting groove 15 to seal the top end opening of the injection groove 11.
[0027] When the test liquid needs to be detected by the test card, the needle enters the injection groove 11 through the sealing film 5 and the silica gel piece 2, the test liquid is injected into the injection groove 11 through the needle, and then the needle is pulled out. The silica gel piece 2 is arranged to prevent the test liquid from flowing back and overflowing. The test liquid in the injection groove 11 flows into the detection groove 12 along the first flow channel section 141 of the flow channel 14, thereby wetting the color blocks 3, so as to complete the detection of the test liquid. After the test liquid is detected by the color blocks 3, the excess test liquid flows into the drying groove 13 along the flow channel 14, and the excess test liquid is dried by the drying agent 4 in the drying groove 13.
[0028] The drying agent 4 in the drying groove 13 is selected as activated carbon. Compared with general drying agents 4, the activated carbon drying agent 4 has high adsorption performance. The activated carbon has a very high specific surface area and a rich pore structure, and can quickly adsorb moisture in the material during the drying process, thereby reducing the humidity of the material. The activated carbon drying agent 4 can complete the drying process in a shorter time and has a fast drying speed. In addition, the activated carbon drying agent 4 also has a deodorizing function.
[0029] In order to make the test liquid in the flow channel 14 flow smoothly, the exhaust groove 16 is formed on the surface of the base plate 1, and the exhaust passage 17 is arranged in communication between the exhaust groove 16 and the drying groove 13, so that the exhaust groove 16 and the drying groove 13 are in communication. The exhaust passage 17 is parallel to the third flow channel section 143 of the flow channel 14, and a plurality of abutting blocks 131 are fixedly arranged on one of the inner side walls of the drying groove 13. The plurality of abutting blocks 131 are located between the exhaust passage 17 and the third flow channel section 143 of the flow channel 14, and the height dimension of each abutting block 131 is lower than the depth dimension of the drying groove 13. After the drying agent 4 is installed into the drying groove 13, one side of the drying agent 4 abuts against the abutting blocks 131. When the test liquid needs to be detected by the test card, the exhaust groove 16 is pierced, so that the gas in the flow channel 14 is discharged from the gap between the abutting blocks 131 and the sealing film 5 into the exhaust passage 17, and finally discharged from the exhaust groove 16, so as to make the test liquid in the flow channel 14 flow smoothly. At the same time, the abutting blocks 131 block the test liquid flowing out of the flow channel 14, so as to prevent the test liquid from flowing directly into the exhaust passage 17 and flowing out of the exhaust groove 16.
[0030] Reference Fig. 5, in order to prevent the amount of excess to be measured liquid too large, so that the drying agent 4 in the drying tank 13 can not be completely absorbed. In the second flow channel section 142 of the flow channel 14 is provided with a liquid storage tank 18, the excess to be measured liquid directly from the first flow channel section 141 flow into the liquid storage tank 18, so that the excess to be measured liquid in the liquid storage tank 18 storage. And between the detection tank 12 and the liquid storage tank 18 through the opening is provided with a drain 19, so that the excess to be measured liquid into the detection tank 12 can be discharged from the drain 19 to the liquid storage tank 18, to avoid the excess to be measured liquid in the detection tank 12 accumulation.
[0031] Referring to Fig. 6 The sealing cover is provided on the surface of the substrate 1 sealing film 5 is selected as the PET film, PET film has excellent transparency and gloss, can provide good visual effect, when the detection of the to be measured liquid can observe the internal to be measured liquid detection. PET film has good moisture resistance and air tightness, thus can play a good sealing effect of the detection tank 12 and the drying tank 13. PET film also has good chemical properties, good resistance to chemicals and oil, so that the sealing film 5 will not be corroded by the to be measured liquid. In order to make the test card paper has good structural strength, the bottom surface of the substrate 1 is provided with a plurality of reinforcing ribs 7, so that the test card paper is not prone to deformation phenomenon.
[0032] The specific implementation principle of the embodiment of the application is: when the test card paper is needed to detect the to be measured liquid, the needle containing the to be measured liquid is inserted through the sealing film 5 and the silica gel piece 2, so as to inject the to be measured liquid into the injection tank 11, and the silica gel piece 2 is good airtightness to prevent the to be measured liquid backflow. At the same time, the exhaust groove 16 is pierced, so that the air in the flow channel 14 can be discharged from the gap between the abutting block 131 and the sealing film 5 to the exhaust passage 17, and then discharged from the exhaust groove 16 along the exhaust passage 17, so that the to be measured liquid in the flow channel 14 flows smoothly. The to be measured liquid entering the injection tank flows along the flow channel 14, flows into the detection tank 12 at the first flow channel section 141 to wet the color blocks 3, and is detected by the color blocks 3. The detection of the to be measured liquid inside the test card paper can be observed through the sealing film 5.
[0033] The excess to-be-tested liquid flows into the liquid storage groove 18 along the first flow channel section 141 to be stored, at the same time, the excess to-be-tested liquid in the detection groove 12 also flows into the liquid storage groove 18 from the liquid outlet 19 to prevent the to-be-tested liquid from accumulating in the detection groove 12. When the to-be-tested liquid in the liquid storage groove 18 is stored to a certain height, the excess to-be-tested liquid flows into the drying groove 13 along the third flow channel section 143, and the abutting block 131 in the drying groove 13 blocks the excess to-be-tested liquid to prevent the excess to-be-tested liquid from flowing into the exhaust passage 17 and overflowing from the exhaust groove 16. The excess to-be-tested liquid flowing into the drying groove 13 is absorbed by the drying agent 4 to prevent the excess to-be-tested liquid from overflowing. The drying agent 4 in the drying groove 13 is selected as activated carbon to have a faster adsorption speed on the to-be-tested liquid.
