Background

The existing vaginal secretion analyzer can realize the dry-type chemical index and morphological index integrated detection of the vaginal secretion and automatically interpret the detection result, thereby comprehensively evaluating the vaginal microecology and assisting the diagnosis and treatment of vaginal diseases. However, most of the current vaginal secretion analyzers lack a detection pretreatment module and are not fully automatic in the true sense. The pretreatment of detection is that after a vaginal secretion sample is collected by using a cotton swab, the cotton swab is transferred into a treatment tube, and a diluent is dripped to uniformly mix the vaginal secretion sample on the cotton swab to prepare vaginal secretion sample liquid for detection of an analyzer. The process is mainly operated manually. It has been shown in the study that in the manual execution of a complete sample testing process, the pre-processing time before testing the test sample can account for 57.3% of the total sample analysis process, while the error occurring in the pre-processing operation accounts for 70% of the total error, thus requiring high subjectivity and experience for the operator. In addition, the manual pre-detection process for a complete vaginal secretion sample generally requires 1-2 minutes, and for a large-scale hospital, the number of routine examination of the vaginal secretion can be as high as thousands of cases per day, and the pre-detection process of the vaginal secretion by light can overload the operator.
