Problems solved by technology

[0004] However, in practice, it is found that conventional electronic pregnancy test pens often have the problem that the chromatography cannot be carried out smoothly and cannot be detected correctly due to poor contact between the suction stick and the test strip.

Embodiment 1

[0039] A suction rod fixing mechanism for a detection device, such as figure 1 As shown, it includes: a fixing seat 100 and a shrapnel 200 .

[0040] The fixing seat 100 includes a bottom plate 110 and two side plates 120, the two side plates 120 are respectively arranged on two opposite edges of the bottom plate 110, together with the bottom plate 110, they enclose and form a receiving portion with an open top, and one end of the receiving portion It is used to connect and fix with the detection device, and the other end is an open end, such as figure 2 shown.

[0041]The tops of the two side plates 120 are respectively provided with blocking parts 121 extending relatively. In this embodiment, the blocking member forms a gap at the place where the accommodating portion is connected and fixed with the detection device.

[0042] The shrapnel 200 is made of metal and is integrally formed, such as image 3 As shown, the elastic piece 200 includes a locking part 210 , an exte...

Embodiment 2

[0053] This embodiment is basically the same as that of Embodiment 1, except that no undercut is provided on the shrapnel of this embodiment.

experiment example

[0061] The detection device (electronic pregnancy test pen) of the above-mentioned embodiment and comparative example was used for early pregnancy detection, and the effect of sample loading chromatography was investigated, and the results are shown in the following table.

Abstract

The invention relates to a detection device and a sample suction rod fixing mechanism and assembly method thereof. The fixing mechanism comprises a fixing base and an elastic sheet. The fixing base comprises a bottom plate and at least two side plates arranged on the two opposite edges of the bottom plate respectively, and the bottom plate and the side plates together define a containing part with the top open; one end of the containing part is used for being fixedly connected with the detection device, and the other end of the containing part is an open tail end; stopping components extending oppositely are arranged at the tops of the side plates respectively. The elastic sheet comprises a clamping part, pressing parts and guiding parts in a sequential connection mode, the clamping part is used for being fixedly connected with the detection device, the pressing parts are located in the containing part, an installation space for containing a sample suction rod is formed between the pressing parts and the stopping components, and the guiding parts extend to the bottom plate and the tail end of the containing part from the pressing parts. By adopting the fixing mechanism, the contact tightness between the sample suction rod and a test strip is greatly improved, smooth chromatography can be well promoted, and product reliability is improved.

Description

technical field [0001] The invention relates to the technical field of biological sample detection, in particular to a detection device for biological sample detection, a suction rod fixing mechanism and an assembly method thereof. Background technique [0002] At present, the detection products used for early pregnancy detection mainly include two types, one is test strips, test paper cards or pregnancy test pens that need to be interpreted by human eyes; the other type can be automatically interpreted by machines Electronic pregnancy test pen, etc. [0003] Generally speaking, the electronic pregnancy test pen includes test strips for detection, detection devices for interpreting results (including photoelectric sensors and single-chip microcomputers, etc.), suction sticks for loading samples on test strips, and The case where the components are mounted. In these electronic pregnancy test pens, the suction stick part is installed in the electronic pregnancy test pen thro...
