As shown in fig. 2, the gold colloidal detection plate 3 of this embodiment includes a housing 31, at least two (five in this embodiment) gold colloidal test strips 32 arranged in parallel are integrated in the housing 31, each gold colloidal test strip 32 includes a sample pad, a marker pad, a nitrocellulose membrane and a sample sucking pad, the marker pad is coated with a gold colloidal label or an enzyme-labeled anti-lemon yellow antibody, a detection line of the nitrocellulose membrane is coated with a lemon yellow serum albumin conjugate, a quality control line of the nitrocellulose membrane is coated with a secondary antibody specifically bound to the anti-lemon yellow antibody, the structure of the gold colloidal test strip 32 is well known in the art, and is not described in detail in this embodiment.
In order to facilitate sample adding and detection result observation, a sample adding port 31a corresponding to each sample pad and an observation window 31b corresponding to each nitrocellulose membrane are formed on the top surface of the housing 31, and a detection line mark 31c and a quality control line mark 31d located at the outer edge of the opening of each observation window 31b are also provided, and the detection line mark 31c and the quality control line mark 31d respectively correspond to the positions of a detection line and a quality control line on the nitrocellulose membrane.
As shown in fig. 4, in the present embodiment, the sample addition port 31a is funnel-shaped, and the opening size of the funnel-shaped sample addition port 31a gradually decreases from the outer side of the housing 31 to the sample pad; so both can obtain the sample loading port 31a that the volume is bigger, can guarantee again that the urine sample is more concentrated on the sample pad, make the testing result more accurate. In an unused state (as shown in fig. 2), the moisture-proof film 33 is adhered to the outer edge of the opening of each sample addition port 31a of the colloidal gold detection plate 3, and the moisture-proof film 33 and the sealing bag 4 play a double-layer moisture-proof and soil-proof role in the colloidal gold test strip 32; meanwhile, the observation window 31b is not a hollow window, but is hermetically provided with a perspective piece which can be made of glass, transparent plastic and other materials, so that the detection result of the colloidal gold test strip 32 can be conveniently observed, and the moisture-proof and soil-proof effects can be achieved; unlike the moisture barrier film 33 and the sealed pouch 4, the see-through is generally configured to be non-removable.
When the colloidal gold detection plate 3 is not used, as shown in fig. 1, the colloidal gold detection plate 3 is packaged in a sealing bag 4, and when the colloidal gold detection plate is used, the colloidal gold detection plate 3 is taken out and fixedly mounted on the inner supporting seat 2 for reuse.

Because the colloidal gold detection plate 3 is relatively thin, when the clamping groove position 22 is deep, the colloidal gold detection plate 3 cannot be pushed in place, and the taking-out is inconvenient. Therefore, as shown in fig. 3 and 4, in the present embodiment, a sub push-pull opening 21a communicating with the detection plate inlet/outlet 22a is provided in the side surface of the casing 31, and the sub push-pull opening 21a has a semicircular shape and is located at the middle end of the detection plate inlet/outlet 22 a. The auxiliary push-pull opening 21a can facilitate pushing and pulling the colloidal gold detection plate 3 without affecting the limiting effect of the detection plate outlet/inlet 22a on the colloidal gold detection plate 3.
In addition, as shown in fig. 1, 3, 4 and 5, at least two reagent tube slots 21b are formed on the top surface of the holder body 21. When in use, the reagent tube containing the urine sample to be detected is placed in the reagent tube groove 21b, and then a dropper is adopted to sample from the reagent tube and add the sample to the corresponding sample adding port 31 a; the inner support holder 2 is used as a reagent tube holder at the same time.
The working principle of the kit for detecting the colloidal gold in the urine sample is as follows:
opening the outer box 1, taking out the sealed bag 4 packaged with the colloidal gold detection plate 3, taking out the inner supporting seat 2, and sequentially placing the reagent tubes containing the urine sample to be detected into the reagent tube grooves 21b for later use; the sealing bag 4 is disassembled, the colloidal gold detection plate 3 is taken out, the moisture-proof films 33 adhered to the sample addition ports 31a are torn off, and the colloidal gold detection plate 3 is placed into the clamping groove 22 from the detection plate inlet and outlet 22a on the side surface; the inner supporting seat 2 can be directly placed on a working table for use, or can be placed into the outer box 1 for use; a user adopts a dropper to sequentially take urine samples from the reagent tubes, adds the urine samples into the sample adding ports 31a from the operation ports 22b in a one-to-one correspondence manner, and then observes the detection results of the colloidal gold test strips 32 at the observation windows 31 b; after the detection is finished, the colloidal gold detection plate 3 is taken out and discarded, and the inner supporting seat 2 can be left for reuse.
