Problems solved by technology

[0003] At present, the existing BV detection tools on the market are mainly BV rapid detection kits, three main detection methods: polyamine method, enzyme chemical reaction, and sialidase method. The main functions of this type of product are incubation and colorimetry , it is necessary to manually control the time and judge the negative and positive, the manual operation is cumbersome, and the subjective error of visual inspection and inaccurate manual timing of incubation time will have a certain impact on the test results
[0004] Now, BV detectors are beginning to develop towards fully automated detectors integrating sample addition, temperature control, detection, and report output. However, the existing BV rapid detection kits and BV detectors have a low degree of automation, and the detection process is cumbersome. Judgment is greatly influenced by people's subjective

[0034] See Figure 1-Figure 7 , figure 1 It is the structural diagram when the automatic bacterial vaginosis detector in Example 1 of the present invention is opened; figure 2 It is a top view structure diagram of the automated bacterial vaginosis detector in Example 1 of the present invention; image 3It is a top view structural diagram of the main devices in the automated bacterial vaginosis detector in Example 1 of the present invention; Figure 4 It is a schematic structural diagram of the sample adding device in the automated bacterial vaginosis detector in Example 1 of the present invention; Figure 5 It is a schematic diagram of the front structure of the heating plate in the automatic bacterial vaginosis detector in Example 1 of the present invention; Figure 6 It is a schematic diagram of the back structure of the heating plate in the automated bacterial vaginosis detector in Example 1 of the present invention; Figure 7 It is a structural block diagram of the de...

Embodiment 2

[0052] See Figure 8 , Figure 8 It is a structural block diagram of the detection device in the automatic bacterial vaginosis detection instrument of Example 2 of the present invention.

[0053] The basic structure of the automatic bacterial vaginosis detector of this embodiment is the same as that of Embodiment 1, the only difference is that the detection device is different.

[0054] In the automatic bacterial vaginosis detector of this embodiment, the detection device 8 is also fixed on the heating plate corresponding to the detection position, and the detection device 8 directly detects the color and color depth of the tested solution. The detection device 8 includes a light source, a color sensor and a main control circuit. After the white light of the light source 87 passes through the sample cup, the color sensor 88 detects the light reflected by the cuvette and then decomposes the reflected light into red, green and blue. , and respectively represent the light inten...

Abstract

The invention discloses an automatic bacterial vaginosis detector, comprising a loading device, an incubation device, a sampling needle device and a detection device, wherein the loading device is used for placing a sample cup; the incubation device is used for incubating a sample; the sampling needle device is used for adding a color developing agent to the sample; the detection device is used for carrying out color developing detection on the sample. Compared with the prior art, by adopting the automatic bacterial vaginosis detector provided by the invention, the automatic degree and the detection efficiency of the bacterial vaginosis (BV) detector can be improved, the stability of enzymatic activity is ensured, cross infection is eliminated, and the failure rate and energy consumption of the detector in operation are reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an automatic bacterial vaginosis detector. Background technique [0002] Bacterial vaginosis (BV) is a common vaginal infectious disease among women of childbearing age. The mixed flora of mycoplasma type is replaced, causing the disease caused by flora imbalance. The main pathogenic bacteria of BV will produce sialidase when they erode vaginal cells, and there is a quantitative relationship between the content of sialidase and BV pathogenic bacteria, and sialidase is an effective marker for detecting BV. BV is diagnosed by detecting sialidase in vaginal secretions using a sialidase substrate. In the presence of sialidase, the hydrolyzed product of the sialidase substrate will undergo a color reaction under alkaline conditions, and the color change can be used to determine whether you have BV. [0003] At present, the existing BV detection tools on the market are mainly BV r...
