[0028] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0029] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0030] Reference Figure 1 and Figure 2 as well as Figure 3 As shown, colloidal gold detection is a commonly used labeling technology, which is a new type of immune labeling technology that uses colloidal gold as a tracer marker and is applied to antigens and antibodies. It has its unique advantages. Most of the existing colloidal gold detection cards 1 are set in a five-card manner. During the detection process of the existing detection card 1, once the detection sample is dripped into the detection card 1, the detection process cannot be stopped, thereby failing to achieve the problem of limiting the time and quantity of the detection process. In order to solve this type of problem, a colloidal gold five-card is proposed, including a detection card 1, the detection card 1 includes a detection shell 11 and a protective shell 12 detachably connected to the top of the detection shell 11, a detection cavity 121 is opened in the detection shell 11, and a detection member 3 is arranged in the detection cavity 121, and the detection member 3 includes a PVC bottom plate 34 arranged at the bottom of the detection cavity 121, and a sample pad 31 for transmitting a sample solution, a transfer pad 32, a detection pad 22, and an anti-overflow pad 33 are sequentially laid on the PVC bottom plate 34;

[0031] The sample pad 31 has a side protruding upwards near the transfer pad 32, and the protrusion is located between the PVC bottom plate 34 to form a slot 311 for the transfer pad 32 to slide horizontally into;

[0032] The transfer pad 32 is disposed on the PVC bottom plate 34 and slides horizontally along the PVC bottom plate 34, and one end of the transfer pad 32 away from the sample pad 31 bulges upward to abut against the top of the detection pad 22, and a driving member for driving the transfer pad 32 to slide horizontally to connect or disconnect the detection pad 22 is disposed on the upper side of the transfer pad 32;

[0033] The detection pad 22 is laid flat on the PVC bottom plate 34, and the detection pad 22 contains a reagent for performing a detection reaction on the sample solution;

[0034] The anti-overflow pad 33 is laid on the top of the PVC bottom plate 34, and one end close to the detection pad 22 extends upward to the top of the detection pad 22 for absorbing the overflowed excess sample solution; a relatively stable detection environment is formed by the combination of the detection shell 11 and the protective shell 12, and the setting of the sample pad 31, the transfer pad 32, and the detection pad 22 in the detection member 3 can achieve the purpose of orderly transmission of the detection sample, and the operation of the driving member can achieve the connection between the transfer pad 32 and the detection pad 22, thereby cutting off the transmission path of the detection sample, achieving the purpose of time-limited and quantity-limited control of the detection process, and the setting of the anti-overflow pad 33 can achieve the purpose of absorbing and protecting the detection sample overflowing the detection pad 22.

[0035] It should be noted that the sample pad 31, transfer pad 32, detection pad 22, and anti-overflow pad 33 are all capable of transmitting the detection sample solution, and the PVC base plate 34 arranged at the bottom will not absorb the sample solution, thereby ensuring the purpose of the entire detection process being carried out in an orderly manner.

[0036] Further, see Figure 4 As shown, the specific structure of the above-mentioned driving member is as follows: the driving member includes a guide groove 112 opened in the protective shell 12, and a push block 13 is provided in the guide groove 112 for horizontal sliding, and the push block 13 is arranged on the top of the transfer pad 32; the push block 13 can drive the transfer pad 32 to slide horizontally by the horizontal sliding of the push block 13 in the guide groove 112, so that the transfer pad 32 is separated from the detection pad 22, and after the transfer pad 32 and the detection pad 22 are separated, the transmission path of the detection sample solution is cut off, which can ensure the purpose of ensuring the time limit and quantity limit mentioned in the detection process.

[0037] In addition, the pushing of the push block 13 is actively performed by the inspector, and in the present embodiment, the structural characteristics of the transfer pad 32 itself will not change with the horizontal sliding, that is, after the transfer pad 32 is inserted into the card slot 311, its shape will not change.

[0038] It should also be noted that in order to ensure that the testing personnel can inject the test sample solution into the test card 1 in an orderly manner, in this embodiment, an injection hole 111 is provided on the top of the protective shell 12 and gradually converges inward from top to bottom, and the bottom of the injection hole 111 is located at the top of the sample pad 31; through the setting of the injection hole 111, the test sample solution can enter the sample pad 31 in an orderly manner, thereby being transmitted through the detection element 3.

[0039] In addition, a plurality of display slots 21 for observing the detection results in the detection pad 22 are provided on the top of the protective shell 12, and the display slots 21 gradually gather inward from top to bottom and press against the top of the detection pad 22; the detection pad 22 is provided with detection areas 222 and control areas 221 for displaying the detection results at intervals; the setting of the detection area 222 and the control area 221 can facilitate observation by the detection personnel, and the specific detection reaction of colloidal gold in the detection pad 22 is relatively mature in the prior art, so it will not be repeated in this embodiment.

[0040] It is worth mentioning that the protective shell 12 and the detection shell 11 are detachably connected. In order to ensure a certain connection strength between the two, in this embodiment, a plurality of connecting pillars 4 for fixing the protective shell 12 are provided in the detection cavity 121; the setting of the connecting pillars 4 can ensure that the strength of the connection between the two brackets is sufficient.

[0041] In addition, a limiting plate 5 for limiting the transmission of the solution to the detection element 3 is also provided in the detection housing 11 . The setting of the limiting plate 5 can ensure a certain transmission direction of the detection sample solution.

[0042] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
