The lower cover 24 has a loading platform 242 which is composed of at least one frame unit 244 and at least one first supporting rib 246. As shown in the third embodiment of the embodiment, the frame can be formed by five frame units 244. And the six first support ribs 246 are vertically staggered to form a bottom portion, and constitute a long rectangular area protruding from the bottom surface of the lower cover 24. The bonding means 26 includes a plurality of protrusions 222 disposed around the edge of the upper cover 22, and a plurality of insertion holes 248 corresponding to the protrusions 222 and disposed on the lower cover 24, thereby combining the upper cover 22 and the Lower cover 24. The upper cover 22 is further provided with at least one pressing unit 224 extending toward the first supporting ribs 246 to protrude from the bottom surface of the upper cover 22, as shown in the third embodiment of the embodiment, three The unit 224 is pressed.

As shown in the third and fourth figures, the test strip 30 is a test strip using a lateral flow analysis technique or an immunochromatography, which is disposed in the first chamber 208 and placed on the carrier 242. on. When the upper cover 22 is combined with the lower cover 24, the test strip 30 can be stably positioned on the support base 242 by the pressing of the pressing unit 224. Furthermore, the test strip 30 has a result display area 32 and an absorption area 34, and the result display area 32 is correspondingly disposed at the opening of the window 206, thereby being visible through the window 206 as shown in the first figure. The result display area 32 is directly seen from outside the body 20.

As shown in the second and fourth figures, the fixing base 40 is detachably disposed on the body 20, and has a second chamber 402 and a third chamber 404. The connecting portion 202 is detachably disposed on the second portion. The second chamber 402 has a partition 42 between the second chamber 402 and the third chamber 404. The partition 42 defines a through hole 422. The absorbing area 34 extends through the through hole 422. The third chamber 404. The connecting portion 202 has two opposite ribs 28, and the wall surface of the second chamber 402 is oppositely disposed with two long slots 44, and the ribs 28 and the long slots 44 correspond to each other, thereby The equal ribs 28 and the equal length grooves 44 are fitted to each other, so that the connecting portion 202 is more stably disposed in the second chamber 402 without being easily separated. Furthermore, the fixing base 40 further has at least one second supporting rib 46 extending from the wall of the partitioning member 42 and the third chamber 404 toward the third chamber 404 for receiving Set this Absorption zone 34.

Wherein, the wiping member 50 is made of a material that is porous and has a relatively high hardness, such as foam, felt fiber, etc., so that the sample solution can be inhaled by the wiping member 50 through capillary action, and can be like dust, skin. Dust, dirt, and the like, or other forms of micro-samples, are adsorbed on the wiper 50 by wiping, and are not easily deformed by extrusion during wiping. Further, the joint portion 52 has a contact surface 522, and the contact surface 522 and the absorption region 34 are adhered to each other to increase the contact area between the wiper 50 and the test strip 30 to enhance the sample solution. The efficiency of flow between the wiper 50 and the test strip 30.

The cover member 60 has a fourth chamber 62, and the cover member 60 is detachably attached to the mount 40. When the cover member 60 is closed to the fixing base 40 , the third chamber 404 and the fourth chamber 62 are sealed, and the adsorption portion 54 is disposed in the fourth chamber 62 .

When the lateral flow type detecting device 10 according to the present invention is used, the suction portion 54 of the wiper 50 can be wiped back and forth at a place to be detected to adhere the sample to the adsorption portion 54. Next, as shown in the fourth figure, after the reaction buffer is dropped into the fourth chamber 62 of the cover member 60, the cover member 60 is combined with the fixing base 40, and the adsorption portion 54 is immersed in the reaction buffer. Among them, the sample is mixed with the reaction buffer to form a sample solution S. Sample solution S Through capillary action, the joint portion 52, the absorption region 34, and the result display region 42 are sequentially flowed for subsequent analysis reactions. Therefore, the process and steps of the entire inspection can be simplified in the process of use, and it is not necessary to cooperate with other inspection and mixing tools, such as cotton swabs, droppers, test tubes, etc., to achieve better usability.
