Detailed Description

The technical solution of the present invention will be described in detail by the following embodiments.

As shown in fig. 1-2, fig. 1 is an exploded view of a sample liquid collecting device according to the present invention; fig. 2 is the utility model provides a sample liquid collection system's inner structure schematic diagram.

Referring to fig. 1-2, the utility model provides a sample liquid collection system, include: the method comprises the following steps: reagent bottle 1, end cap 2 and sampling stick 3, wherein:

the reagent bottle 1 is filled with reagent, and a sealing film 4 for sealing the opening of the reagent bottle 1 is arranged at the bottle mouth. The plug 2 is adapted to the mouth of the reagent bottle 1 so that the plug can be screwed into the mouth of the reagent bottle and seal the mouth of the reagent bottle, the dropping liquid pipeline 22 penetrating through two ends of the plug 2 is arranged inside the plug 2, the cap 5 is sleeved at one end of the plug 2, and the puncture needle 51 is arranged on the cap 5. Sampling stick 3 is located end cap 2 and keeps away from the one end of cap 5, and sampling stick 3's one end is connected with end cap 2, and its other end is equipped with sampling head 31.

When the sampling device is used, a collecting head on the sampling rod 3 is used for collecting a sample, a puncturing needle 51 on the cap 5 is used for puncturing a sealing film 4 on the reagent bottle 1, and the plug 2 is screwed into the reagent bottle 1, so that the sampling rod 3 can be inserted into the reagent bottle 1, and the sample is contacted with a reagent in the reagent bottle 1 to obtain a sample liquid which can be tested; when the sample liquid needs to be obtained, the cap is only required to be detached, so that the sample liquid can flow out of the dropping liquid pipeline 22, and the dropping amount of the sample liquid can be controlled well.

By the above, the utility model provides a sample liquid collection system uses and convenient to carry, and can effectively avoid sample liquid to spill the phenomenon in acquireing and the censorship stage.

In addition, in this embodiment, one end of the cap 5 has a first assembling groove for the plug 2 to screw in, one end of the cap 5 away from the first assembling groove has a second assembling groove for the reagent bottle 1 to screw in, and the bottom of the second assembling groove is provided with a conical protrusion towards the direction away from the first assembling groove to form the puncture needle 51. After the sample is diluted with the reagent, the cap 5 may be removed from the stopper 2, and the cap 5 may be directly mounted on the reagent bottle 1 using the second mounting groove of the cap 5.
