Problems solved by technology
[0003] However, there are many technical defects in the multi-index detection of vaginal secretions on the market: the detection sensitivity and specificity of some indicators including mold and Trichomonas vaginalis are low, and the highest is only 60% to 70%.
The operation is relatively cumbersome, and it is necessary to add specimen solution and chromogenic solution or stop solution many times, which is easy to cause pollution, is difficult to meet the needs of clinical testing, and limits its application in home self-testing; in order to make up for the shortcomings of existing technologies, it is necessary Looking for a vaginitis self-detection device

Embodiment 1
[0022] Embodiment 1 The present invention discloses a vaginitis self-detection device, which includes a base plate and a cover plate adapted thereto. The base plate is provided with a sample loading area 2, a dry chemical reaction area 4 and an immunochromatographic area 3, and a dry chemical reaction area. Area 4 is located at one end of sample loading area 2, and contains 3 reaction wells, each reaction well is 3mm deep, with a partition, not connected to each other. column to prevent the reagent block from falling off. The reaction hole is connected with the sample loading area 2 through a small groove.
[0023] The immunochromatography area 3 is located on the other side of the sample loading area 2 and includes a sample pad 31 , a conjugate release pad 32 , a chromatographic membrane 33 and an absorbent paper 34 . The sample pad and conjugate release pad are made of glass fiber membrane, and the chromatographic membrane is preferably nitrocellulose membrane. Three horiz...

Abstract
The invention belongs to the technical field of in-vitro diagnosis, and particularly relates to a self-testing device for colpitis. The device comprises a base plate and a cover plate matched with the base plate. The base plate comprises a sample adding area, a dry chemical reaction area and an immunochromatography area. The immunochromatography area is located on one side of the sample adding area, and the dry chemical reaction area is located on the other side of the sample adding area; the dry chemical reaction area comprises three side-by-side reaction holes, the reaction holes are not communicated with one another, and each reaction hole is communicated with the sample adding area through a connecting groove. The sampling area is communicated with a sample pad and the reaction holes, multi-index detection can be completed through one-time sample adding, the sample adding area is higher than the reaction holes, and the different reaction holes are not contaminated. The dry chemical enzyme method and the immunochromatography method are combined, the immunochromatography method is used for detecting molds and trichomonad, the detection sensitivity and specificity of molds and trichomonad in the dry chemical enzyme method are improved from 60-70% to 85% or above, and the great market prospect and economic value are achieved.
Description
technical field [0001] The invention belongs to the technical field of in vitro diagnosis, and in particular relates to a vaginitis self-detection device. Background technique [0002] At present, the detection of vaginitis mostly adopts the dry chemical enzyme method, and various biochemical indicators are used to detect various pathogenic microorganisms in vaginal secretions. Common ones include the detection of probiotic Lactobacillus in the vagina with hydrogen peroxide, the detection of leukocytes with esterase, the detection of bacterial vaginosis (BV) with sialidase and proline aminopeptidase, and the detection of bacterial vaginosis (BV) with pH indicators and acetamido Glucosidase for mold and trichomonas and β-glucuronidase for aerobic vaginitis. The detection card adopts four to eight multi-indicator detection devices, which are composed of a bottom plate and an upper cover adapted to it, or an integrally formed device, and various reagents and reagents required ...
