Problems solved by technology
For sample ports with quantitative requirements and sealing requirements, sample ports with this type of structure cannot meet the requirements
And there is a risk of liquid sample leakage in the open sample injection port structure during operation, so the operator must be careful before
In addition, special tools must be used when adding samples. If the operator does not pay attention to adding a little more liquid, it will cause liquid overflow and pollution.
In addition, some diagnostic test cards on the market have sealing caps on the sampling port, but no quantitative function.

Embodiment Construction
[0038] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.
[0039] figure 1 It is a structural schematic diagram of an in vitro diagnostic test card. Such as figure 1 As shown, the test card includes a top cover 1 , a fluid channel unit formed by a sealing cover 2 , a main body 3 and an elastic sealing gasket 4 , a printed circuit board 5 , and a bottom cover 6 in sequence.
[0040] The sample injection port structure includes an upwardly protruding cylinder whose inner wall forms a sample pool, an annular overflow tank located on the periphery of the cylinder, and a through hole...

The invention relates to an in vitro diagnosis test card sample feeding port structure and an in vitro diagnosis test card. The test card sequentially comprises an elastic sealing cover and a main body, wherein the main body comprises a reagent pool, a sample pool and a waste liquid pool as well as microfluidic channels, the reagent pool, the sample pool and the waste liquid pool are formed on one side of the elastic sealing cover, the microfluidic channels are arranged on opposite sides, an inlet of each microfluidic channel is communicated with each reagent pool and sample pool through an unsealing port, and an outlet of each microfluidic channel is communicated with the waste liquid pool; a sample pool sample feeding port structure comprises an upward raised barrel of which the inner wall forms the sample pool, an annular overflow groove is formed on the periphery of the barrel, and a through hole which is communicated with the waste liquid pool is formed on the bottom of the overflow groove; the elastic sealing cover is provided with an annular bulge the other side of which is matched with the outer wall of the overflow groove of the 5sample pool in a sealing manner. By adopting the structure, liquid can be quantitatively loaded whether by a special tool such as a pipette or by a general tool such as an injector; the overflow of surplus liquid can be prevented to a certain extent, so that the pollution is avoided; liquid inside the sample pool can be sealed.
Description
technical field [0001] The invention relates to an in vitro diagnostic test card sample inlet structure and an in vitro diagnostic test card, in particular to an in vitro diagnostic test card with a liquid sample inlet structure with quantification, sealing and overflow prevention functions. Background technique [0002] Most of the liquid sample loading ports (abbreviated as sample loading ports) of diagnostic test cards currently on the market are open, so they do not have quantitative and sealing functions. For sample ports with quantitative requirements and sealing requirements, sample ports with this type of structure cannot meet the requirements. And there is a risk of liquid sample leakage in the open sample injection port structure during operation, so the operator must be careful. In addition, special tools must be used when adding samples. If the operator does not pay attention to adding a little more liquid, it will cause liquid overflow and pollution. In additi...
