Problems solved by technology

The dropper is made of soft and elastic PE material, with one end sealed and the other open. Although some open ends have scale marks, it is difficult for non-professionals to operate when collecting a small amount of blood samples (for example, 5 microliters). Air bubbles are likely to be generated or the sample is squeezed out by misoperation during transfer; and the repeated use of the diluent bottle is also likely to cause contamination, so sample collection transfer and possible diluent contamination are problems faced by every operator, especially non-professionals. Therefore, how to provide a matching detection device that can accurately and quantitatively collect samples and ensure no pollution is an urgent problem to be solved at present.

Embodiment 1

[0031] like Figures 1 to 4 , Image 6 As shown, the detection device for quantitatively collecting samples is prepared, and the device includes: a disposable storage container 2, the storage container 2 has a sealed end 3 and an open end 4, and a fluid is arranged between the open end 4 and the sealed end 3, A sealing liquid is provided adjacent to the opening end 4, and the sealing liquid is a viscous liquid. The storage container 2 is formed into a sealed long tube structure, and the sample is directly attached to the opening end 4 to complete sampling or the side wall of the opening end 4 is provided with a ventilation structure. To assist sampling, the ventilation structure is a notch 10 provided on the side wall of the opening end 4, and the sample flows into the opening end 4 through the notch 10, or the ventilation structure is provided on the pipe wall between the opening end 4 and the sealing liquid. There is a ventilation hole 11, the diameter of the ventilation ho...

Embodiment 2

[0042] like figure 2 and Figure 7 As shown, the casing 6 wraps the test paper and exposes the sample gasket 7 and the test result display area 8 in the sample loading area. The casing 6 is provided with two sample loading holes 9-1 and 9-2. The pipe diameter of the opening end 4 is compatible with the sample injection hole 9-1 and the sample injection hole 9-2 in the sample injection area.

[0043] The detection steps when the housing 6 is provided with two sample injection holes 9-1 and 9-2: when the required sample volume is 5 microliters, the open end 4 is directly attached to the sample to complete the sample collection, and then Insert the storage container 2 downward into the sampling hole 9-1, the sample on the opening end 4 is fully in contact with the sample pad 7, after the sample is sucked, insert the storage container 2 into the sampling hole 9-2 again, the sampling hole 9 -2 Fix the open end 4, break off a closed end 3 along a knife mark on the tube wall of th...

Abstract

The present invention discloses a detection apparatus for quantitatively sampling samples, and a detection method thereof. The apparatus comprises: a disposable storage container, wherein the storage container is provided with a sealed end and an opening end, a fluid is arranged between the opening end and the sealed end, the position adjacent to the opening end is tightly combined with the fluid through a sealing liquid, the storage container forms a sealed long pipe structure, the sample is directly attached to the opening end or the side wall of the opening end is provided with a gas ventilation structure, and the periphery of the sealed end is provided with an opening structure; and a detection body, wherein the detection body comprises a housing, the housing wraps test paper strip, and a sample pad and a detection result display area are exposed. The detection apparatus has advantages of convenience, rapidness, simple operation, accurate result and the like, and is suitable for detecting substances requiring detection in blood, wherein the substances requiring detection comprise HIV antibodies, hepatitis B surface antigen, dengue fever antibodies, tuberculosis antibodies and the like.

Description

technical field [0001] The invention belongs to the field of disease detection, and in particular relates to a detection device for quantitatively collecting samples and a detection method thereof. Background technique [0002] Using blood as a sample to detect diseases and applying immunochromatography technology, a variety of different diagnostic reagents have been developed and applied in different disease detection fields, such as: detection of tumor markers, early prediction of cardiovascular diseases, infection Screening tests for similar diseases, etc. As a more commonly used sample source, blood, especially fingertip blood, has been widely adopted by various platforms because of its minimally invasive and rapid blood collection. [0003] In order to collect fingertip blood conveniently, the application number in the prior art is: CN200910201449.3, which includes a blood collection dropper and a diluent bottle for repeated use. The dropper is made of soft and elasti...
